附录motor vehicles and the use of additional devicesSelf-loading vehicle arm (also known as hydraulic multi-energy vehicles and fighting for self-loading and unloading trucks) is characterized by separate cargo body fight with the implementation of a goods vehicle and a number of joint fighting operations, the cycle of transport, which can Self-loading dump containers, precast, machine equipment, bulk materials. The use of the car changed a number of operating the previous system under which the motor transport vehicle must be equipped with cranes or loaders, forklifts, loading and unloading as well as the need for workers in many ways, and saved the car and truck loading of the waiting time, increased turnover of motor vehicles and utilization, thus saving a great deal of manpower, material and financial resources to enhance economic efficiency.At present, the arm-type self-loading vehicle mainly used for mining of mineral aggregate loading, transport and dump, factory parts and rough handling and waste dumping, and construction waste from the handling, more clearance for the urban sanitation sector transportation of refuse. Arm as a result of self-loading cargo vehicles and body is separate from the fighting, using fixed-point garbage collection from time to time. Thus, in particular focal point for residents, as well as the market changes with the seasons the amount of waste sites. Dump it and refuse collection vehicles and forklift formula and flip-shaped seal trash dump trash garbage truck with a circular intake compared Yun, can effectively overcome the operation of the secondary dust and noise pollution.Arm-type truck with a low investment and low operating costs, maintenance and convenient, less noise, no secondary dust pollution, etc. Yang. The drawback is the size of the litter bucket, and can not be placed in the narrow streets, while in transit light foam filled refuse to take full advantage of easy self-loading vehicle arm, some cities have begun to establish a centralized garbage removal station, the use of small land transport equipment (such as human dump 3) refuse to focus on narrow streets inthe refuse collection points (floor), and then installed in self-loading arm dedicated junk car in the bucket, and then outward through the self-loading dump truck. It solved the problem of narrow streets could not place the issue of special garbage bucket. To address self-loading arm in the process of motor transport issues dusty materials, Special Purpose VehicleNanning has been designed and built two more effective anti-dust materials, additional devices and drivers can be manipulated to drive the entire operating room Process control device shaft. Are presented below.1, the activities of the vehicle hydraulic cargo canopyThis is to prevent the arm of a self-contained hopper car loading and unloading of materials from blowing out of the vehicle cargo canopy.The structure of the device as shown in Figure 1.Its working principle is: to promote the distribution of hydraulic valve joystick , hydraulic oil into the fuel tank on the cavity, the extended piston rod back, while driving the main arm to the car in front of swing in the tarp , under the canopy of the self and the main arm driven by its front-end articulated main arm , so that folding the sheeting under the lotus back then, under the support of opening up, in the cargo box form a closed top of the Ji Flip cover So that is not contained in the transportation field were filled. When the joystick struck the opposite side, the oil into the fuel tank of the cavity, the protruding rod back, while driving the main arm to the car in front of swing, in the sheeting , Peng-rod self-respect and the main arm Under the impetus of sheeting , Peng-rod and the main arm sequence neatly folded in boxes weeks before the edge, the canopy opened, is expected to facilitate loading and unloading cargo. The device structure is simple and easy to use, especially suitable for the shape of the size of cargo bucket inconsistent. Stacker hopper occasions too, such as good use of cover, fighting to prevent the material goods in the transportation out of dust.2, swing-wing self-loading automatic car coverThe new device structure as shown in Figure 2. When the arm-type self-loading vehicle operations, to manipulate the distribution of multi-way valve stem so that the car swings arms back, when Hopper was slowly lifting, at the same time, as the arm and fixed in the frame side on the small pulley gradually widened the distance that the rope the role of the length of stretch, this time through the wire rope to pull pulley and shaft , with the shaft link a fixed rear cover.Then gradually open up. When the pendulum swing back to the largest angle(that is unloaded or loaded Doo Doo), the rear cover has also opened up to the maximum point of view, are not to affect the loading or unloading hopper. Action in the above-mentioned process, as a result of the front cover through the connecting arm empty set of fixed beams in the arm , so the former self-covered under the arm placed in the vertical with the ground manipulation of self-handling car so that after the swing arm for operating the dumping of operations in the interior height of the front cover lifted.Automatically cover the wing structure is simple and no special operation when used with other types of enclosures covered compared to savings of time and energy, elegant shape, covered with a good hopper to prevent the material from blowing out during transport . Arm of the two self-loading and unloading of motor vehicles Therefore, the role of the former self-cover, the arm placed in the vertical with the ground before the front cover is always tight cover of the hopper. When the arm continues to swing back, the front cover self-lap, the left (on the icon in terms of) when shaft can not continue to lap, when the front cover with the arm before and after lifted up, placed in the largest arm angle, the front and back covers are lifted up, the shape of the wings to take off. At this point, you can do for fighting and has no effect on operations. When the manipulation of self-handling car so that after the swing arm for operating the dumping of materials, dumping hopper to achieve perspective, the rear cover open up to the point of view of a considerable discharge does not affect operation. The front cover as a result of self-hood has always been tight right hopper Department, the work does not affect the discharge. The front cover is designed to sway with the weight and to reduce operations in the interior height of the front cover lifted. Automatically cover the wing structure is simple and no special operation when used with other types of enclosures covered compared to savings of time and energy, elegant shape, covered with a good hopper to prevent the material from blowing out during transport . Arm of the two self-loading and unloading of vehicles attached devices, can effectively prevent materials from blowing out during transport, but their advantages and disadvantages. General self-loading arm in loading and unloading motor vehicles, the workers can only stand on the side of the body, handling agencies to manipulate the distribution of multi-way valve, so that the arm raise hopper or hopper dumping of materials. This appeared in a lot of inconvenience.浅谈自装卸汽车及附加装置的运用摆臂式自装卸汽车(也叫液压多能车和可换斗式自装卸车)的特点是货斗与车体分开，实行一辆车和数个货斗联合作业，循环运输，即能自装自卸集装箱、预制构件、整机设备、散装物料等。

附录附录A（英文文献原文）Unloading of bulk cement tank cargas tank designAbstract:This article discusses the gas tank car unloading of bulk cement to determine the shape of the tank structure, fluidized bed design, introduced the tank volume and load calculation.I. IntroductionGas tank car unloading of bulk cement transport and unloading of bulk cement to air a special car. It is the vehicle chassis in the shape of a cement plant in closed containers and accessories, and an air compressor, air compressor to power car engines. Cement compressed air to fluidized bed fluidized, under some pressure, cement transportation by pipeline to a certain height and horizontal distance of the concrete tower.Unloading of bulk cement trucks to gas can not only enhance the level of mechanization of loading and unloading of cement, save labor, reduce labor intensity and improve working conditions, and can reduce cement consumption, lower construction cost, to ensure the quality of cement. Practice shows that, compared with bagged cement handling, use of gas unloading of bulk cement truck, cargo handling efficiency can be increased by15 times, and cement to reduce the losses of about 4%, with significant social and economic benefits in the current timber resource poor country, the energy shortage Next, with great practical significance.Unloading of bulk cement tank gas tank is an important part of the car, which fluidized bed, tank shape, the effective volume and the direct impact on the total volume of gas unloading of bulk cement truck, two important indicators of professional performance - unloading time and the residual rate, and the vast majority of parts for the processing tank parts, therefore, the tank design is a very important task.Ⅱ.Determine the shape of the tank structureTanks are mainly vertical, horizontal, tilt, lifting style and type of trailer and semitrailer, etc.1. All hanging and trailer type, suitable for large tonnage, does not apply to low tonnage terms from the transport efficiency, semi-trailer better than cycling, such as automobile remodeling of XX9160GSN Xinxiang City carrying gas from the discharge of bulk cement trailer , selected EQ140K type tractor, load capacity 10 tons and more, for large-tonnage trucks, cement semi-trailer is a direction.2. Under the same discharge conditions, the vertical tank less than the expected horizontal tank left. Can not required because the vertical guide plate, chamber area of suitable transport is conducive to gas fluidization, the remaining rate is very low. Guide plate with horizontal tank, the tank cornersand more material on the more left. However, the overall layout of vertical tank, the vehicle center of gravity high technical performance of the vehicle impact, it is difficult to overcome the shortcomings of vertical tank.3. Fixed tilt. Discharge speed, remaining low, the higher center of gravity as to solve the problem, could offer a better type. Such as Inner Mongolia First Machinery Factory of ND2629-type bulk cement tanker is inclined horizontal tank, the discharge rate of up to 1.5 tons / min, the remaining rate of 0.2%, compared with JB3971, 1 "gas unloading bulk cement tank car technology ", on required much higher. But very few use this type.4. Lift with pump. Moving tank in a horizontal position, lifting a certain point of time after discharge gas discharge, discharge faster, less material left. Such as special car factory in Kunshan Lifting KS5301GSN type bulk cement tanker with a pump, lifting angle of 20o. However, the addition of a hydraulic lifting mechanism, not only increasing the cost and also increased operating and maintenance costs. With very little.5. Horizontal tank. Array layout in the vehicle's total, do not affect the chassis of the main performance, which is its outstanding advantages, it is the domestic and international air unloading of bulk cement of a type commonly used vehicles.Horizontal tank including the cylinder and head. There are oval-shaped head head, dished the first two, an overall cylindrical tube, with the cylinder body and perfect circle platform portfolio, but also oblique circular cylindricaland rectangular platform portfolio. Kaolv to the tank arrangement of the internal needs of fluidized bed, the total volume in the same circumstances, the third form of Bi Xing Shi effective Rongji before the two big, fluidized bed and Bu Zhi Fang Bian, while easing the tank weight. We therefore propose, horizontal cylinder and the tank should be straight oblique type combination of round table body. The composition of the tank structure shown in Figure 1.Figure l Tank structureⅢ.The design of fluidized bedDetermine the gas fluidized bed is designed for unloading of bulk cement truck key technology. Design goal is to improve the discharge efficiency, reduce tank dead zone, lower residual rate. Fluidized bed gasification bed by the inclined baffle components, end of support board assembly, composed of compression bars and screws.1. Oblique baffle2. Legislative panel3. Bracket4. Gasification board5. Lateral6. Countersunk head screwsFigure 2 Oblique baffle component architecture1. The choice of gasification boardGasification fluidized board is to ensure delivery of cement to meet the important parts, arrangement should be adopted when the block layout. At present, gasification panel are used in our soft, and commonly used are cotton canvas and polyester canvas. Breathable cotton canvas which is good, but easy to damp, sewage plug, so that permeability variation. As the cotton canvas and then rough surface, the remaining material will rise after discharge. Polyester, polyvinyl alcohol and other chemical fiber fabric is not easily wet, smooth etc, but the residual rate of electrostatic effects.2. Oblique baffle component design and calculationOblique baffle design, pay attention to consider reducing the dead zone of cement delivery process, consider the oblique baffle and tank wall welded airtight. To this end, we have designed to improve the structure of helicalbaffle component shown in Figure 2.Inside the tank, not only vertical oblique angled baffle. Horizontal plane is also tilted, so it and the tank complex internal cross-island line. Accurately calculate the oblique baffle size. Material can be cut off to facilitate the success of workers, making welding firm, to ensure airtight performance.First set up the design space equation and the oblique baffle tank space equation, application of computer calculated the intersection, which was inclined baffle size. Figure 3 shows the internal structure of the tankFigure 3 The internal structure of the tankⅣ.Tank volume and load calculationAfter investigation we found that most of the unloading of bulk cement truck gas tank is too large effective volume, that is, the quality of the tank to carry more than the rated load weight. This may be because the designer take into account the angle of repose as cement loading of cement in the jar can not be filled, it may meet the user's desire to want to be able to multi-loading, but there are two important reasons:1. Cement density greater than lt / m.JB3971 • 1 "gas unloading of bulk cement tank car technology" specified; "tank's effective volume, in order to cement density lt / m. Calculated:V = G／rAfter our testing, cement density of 1.28t / m, so by lt / m. To calculate the effective volume of exposure on the big difference, it easy to overload. For example, the design of a car containing quality 10t, most manufacturers will be effective volume of the tank is designed to l1.5m, Akira car drivers before and after using the method will be filled with cement, thus installed 14.72t, overload too much.2. The lack of precise calculation of the effective volumeAs the complexity of the internal structure of the tank, in fact, estimate the volume of calculation is often simplified, the results of large deviations.粉粒物料运输车罐体设计附录B（中文翻译）摘要：本文讨论了粉粒物料运输车罐体结构形状的确定，流态化床的设计，介绍了罐体容积与载重量的计算方法。

拉臂是垃圾车收集垃圾的关键部件，它的质量和性能直接影响到垃圾的收集效率和质量。
因此，在改装设计中，可以考虑使用高强度、耐磨损的材料制作拉臂，提高其抗拉、抗弯和抗磨性能，从而延长使用寿命。
此外，可以考虑在拉臂上增加自动翻转功能，使其能够自动将垃圾箱倒卸到车厢中，提高收集效率和人员安全性。
其次，需要改进垃圾车的卸载系统。
传统的垃圾车卸载系统通常是依靠倾斜式车厢，将垃圾箱倾斜倒卸。
这种方式存在噪音大、卸载不彻底和卸载效率低的问题。
因此，改装设计中可以考虑采用液压卸载系统，通过液压缸实现垃圾箱的水平卸载，减少噪音，提高卸载效率和质量。
另外，需要增加垃圾车的智能化和环保性能。
智能化可以通过在垃圾车上安装传感器和控制系统来实现。
传感器可以用于监测垃圾箱的填充情况和垃圾车的工作状态，控制系统可以实现自动化的垃圾收集和运输，提高工作效率和操作的准确性。
同时，可以考虑在垃圾车上安装尾气处理和噪音降低设备，减少排放和噪音对环境的影响，提高城市环保水平。
最后，需要加强垃圾车的安全性和舒适性。
安全性可以通过在垃圾车上安装安全防护装置来实现，如加装侧撞护栏、倒车雷达等设备，提高操作员和行人的安全性。
舒适性可以通过改善垃圾车的驾驶室环境来实现，如加装空调、音响和舒适座椅等设备，提高操作员的工作舒适度。
综上所述，对拉臂式垃圾车进行改装设计是很有必要的。
通过优化拉臂的结构和功能、改进卸载系统、增加智能化和环保性能以及加强安全性和舒适性，可以提高垃圾车的收集效率和质量，减少对环境的影响，提高城市环保水平。

When the pull device for boom box action, the first cylinder insurance hook action open the trunk insurance hook, trunk lift insurance. Pull lift arm cylinder piston rod elongation from the pull arm, pull arm to pivot around the hinge C clockwise rotation, the hook arm to pull back move. If the frame is equipped with a trunk, the trunk was pushed home ground. When put on the frame, so that the first hook retractor trunk rings, and contraction of the piston rod, pull arm to hinge pivot counter-clockwise rotation axis C, will put on the flat trunk, the insurance cylinder hook action, pull carriagesinsurance hook fixed to the frame to the trunk.When the pull-arm device dumping action, and action for different box, trunk insurance hook dump in the whole process to ensure that tension in the arm and trunk are not isolated, that is pull arm、the linkage through the trunk rack and trunk link between the insurance as one of the hook, by the deputy rear frame hinge pivot clockwise rotation axis D, lifting carriages lifted until the refuse rubbish. Trunk reset, as long as the retraction of cylinder piston rod pull arm, the pulling arm body still hinge pivot point D is the shaft counterclockwise rotation, until the trunk reset.3 La Boom Selection and design of device structure parameters3.1 Device to pull the boom pivot hinge arrangement and geometry of the main structureDetermined by the following three areas:a. Arm by pulling a dump truck performance, it is 5 t pull the best selection of cars from the arm unloading chassis, the chassis can be selected according to the length of pull arm device to determine frame the total length. To ensure the car to pull arm for changing trunk and dumping action by the force of the chassis reasonable and complete the dumping arm pull action pivot hinge rotation axis D of the location should be arranged in behind the rear spring plate from the chassis rear bearing axis, the spacing is about 0 ~ 100 mm.b. According to the first hinge pivot D arm pull for me the beginning of the selected pivot hinge rotation axis C. In the design and production of the actual process of pulling the car arm in arm had appeared during the pull action although the initial state, pull arm lift carriages, failed to pull arm pivot around the hinge C rotation, but with the linkage frame with the rotation around the hinge pivot point D, which can not get trunk open the beginning of fall; when lifting a certain height, the action of gravity in the trunk, the hinge will pivot C a sudden fall, so pull arm, the linkage frame and carriages suddenly drop, resulting in relatively large; in hit, resulting in extremely unsafe for me a smooth action. To resolve this problem, determine the hinge point C of the axis position is especially important. First the one hand, the horizontal axis of pivot C can not above the level layout of pivot D. In addition, by the hinge can pivot C stress analysis know, the hinge pivot axis of C must be below the level of tension hinge pivot arm cylinder head horizontal axis, while the hook arm pull-start action must be arranged in the vertical axis of the hinge pivot between C and the hinge pivot left foot.c. Important geometrical parameters arm pull a pull arm foot radius of gyration for pull the oil boom turning radius of the cylinder piston rod end of radius of gyration of the angle between the two radius. From the above points analysis we know that, The smaller of radius. The greater the force needed to pull the smaller cylinder arm. Meet the requirements underthe premise of arms-for-me pull-foot turning radius, the smaller the better, La boom cylinder rod side radius of gyration R. The bigger the better as far as possible, so that can pull compact boom, operating small space]21[.3.2 The selection of pull arm cylinder and cylinder installation angle y. The range ofDetermined by the following two aspects:a. By mapping method or analytical method to determine the location of the above the hinge pivot and Pull arm geometry and other components, may initially determine the pull-stroke arm cylinder and installation distance.b. Pull arm cylinder mounting angle of La Boom is the important structural parameters of devices. By the former knowledge, pull the boom box or device for carrying out the process of dumping action, pull the oil boom cylinders have to be overcome trunk (full load) resistance torque generated by gravity, and the lifting crane action start unloading boxes when the moment of resistance is the greatest moment of resistance to overcome, and in Boom began pulling action of the hinge pivot device static friction and inertia moment of resistance Maximum torque. So pull arm cylinder mounting angle y. From the previous analysis we know, when angle larger, the pull arm cylinder smaller maximum thrust required, select the pull arm cylinder bore can be smaller.By pulling in the boom cylinder is installed between the frame and trunk floor, oil cylinder installation layout space is limited, so the pull arm cylinder mounting angle range is also very limited. Design principles to children as much as possible to install a large angle, choose the right drawing arm oil pulling arm cylinder bore to meet performance requirements for the use of vehicles, without increasing the cost and fuel tank weight, and easy layout. Analysis and comparison of some domestic manufacturers to produce 5 t pull arm ,the actual design and production of cars and trucks pulling arm experience, 5 t pull arm around the installation space vehicles between 250 ~ 300 mm, the general tension arm cylinder mounting angle should be Taken between 3°~5°.附录B拉臂式垃圾车设计1拉臂车概述拉臂式垃圾车是在二类汽车底盘上装有使车箱具有装载和卸载功能的拉臂架装置的专用汽车。

附录附录A （英文文献原文）Unloading of bulk cement tank car gas tank design Abstract:This This article article article discusses discusses discusses the the the gas gas gas tank tank tank car car car unloading unloading unloading of of of bulk bulk bulk cement cement cement to to to determine determine determine the the the shape shape shape of of of the the the tank tank structure, fluidized bed design, introduced the tank volume and load calculation.I. IntroductionGas tank car unloading of bulk cement transport and unloading of bulk cement to air a special car. It is the vehicle chassis in the shape shape of of of a a a cement cement cement plant plant plant in in in closed closed closed containers containers containers and and and accessories, accessories, accessories, and and and an an an air air air compressor, compressor, compressor, air air air compressor compressor compressor to to to power power power car car car engines. engines. engines. Cement Cement compressed compressed air air air to to to fluidized fluidized fluidized bed bed bed fluidized, fluidized, fluidized, under under under some some some pressure, pressure, pressure, cement cement cement transportation transportation transportation by by by pipeline pipeline pipeline to to to a a a certain certain certain height height height and and and horizontal horizontal distance of the concrete tower.Unloading of bulk cement trucks to gas can not only enhance the level of mechanization of loading and unloading of cement, save labor, reduce labor intensity and improve working conditions, and can reduce cement consumption, lower construction cost, to ensure the quality of cement. Practice shows that, compared with bagged cement handling, use of gas unloading of bulk cement truck, cargo handling efficiency can be increased by 15 times, and cement to reduce the losses of about 4%, with significant social and economic benefits in the current timber resource poor country, the energy shortage Next, with great practical significance.Unloading of bulk cement tank gas tank is an important part of the car, which fluidized bed, tank shape, the effective volume and the direct impact on the total volume of gas unloading of bulk cement truck, two important indicators of professional performance - unloading time and the residual rate, and the vast majority of parts for the processing tank parts, therefore, the tank design is a very important task.Ⅱ.Determine the shape of the tank structureTanks are mainly vertical, horizontal, tilt, lifting style and type of trailer and semitrailer, etc. 1. 1. All All All hanging hanging hanging and and and trailer trailer trailer type, type, type, suitable suitable suitable for for for large large large tonnage, tonnage, tonnage, does does does not not not apply apply apply to to to low low low tonnage tonnage tonnage terms terms terms from from from the the the transport transport transport efficiency, efficiency, semi-trailer better than cycling, such as automobile remodeling of XX9160GSN Xinxiang City carrying gas from the discharge of bulk cement trailer , selected EQ140K type tractor, load capacity 10 tons and more, for large-tonnage trucks, cement semi-trailer is a direction.2. Under the same discharge conditions, the vertical tank less than the expected horizontal tank left. Can not required because the vertical guide plate, chamber area of suitable transport is conducive to gas fluidization, the remaining rate is very low. Guide plate with horizontal tank, the tank corners and more material on the more left. However, the overall layout of vertical tank, the vehicle center of gravity high technical performance of the vehicle impact, it is difficult to overcome the shortcomings of vertical tank.3. Fixed tilt. Discharge speed, remaining low, the higher center of gravity as to solve the problem, could offer a better type. Such as Inner Mongolia First Machinery Factory of ND2629-type bulk cement tanker is inclined horizontal tank, the discharge rate of up to 1.5 tons / min, the remaining rate of 0.2%, compared with JB3971, 1 "gas unloading bulk cement tank car technology ", on required much higher. But very few use this type.4. Lift with pump. Moving tank in a horizontal position, lifting a certain point of time after discharge gas discharge, discharge faster, less material left. Such as special car factory in Kunshan Lifting KS5301GSN type bulk cement tanker with a pump, lifting angle of 20o. However, the addition of a hydraulic lifting mechanism, not only increasing the cost and also increased operating and maintenance costs. With very little.5. 5. Horizontal tank. Horizontal tank. Array Array layout layout layout in in in the the the vehicle's total, vehicle's total, do do not affect the not affect the c hassis chassis chassis of of of the the the main performance, main performance, which which is its is its outstanding advantages, it is the domestic and international air unloading of bulk cement of a type commonly used vehicles.Horizontal tank including the cylinder and head. There are oval-shaped head head, dished the first two, an overall cylindrical tube, with the cylinder body and perfect circle platform portfolio, but also oblique circular cylindrical and rectangular platform portfolio. Kaolv to the tank arrangement of the internal needs of fluidized bed, the total volume in the same circumstances, the third form of Bi Xing Shi effective Rongji before the two big, fluidized bed and Bu Zhi Fang Bian, while easing the tank weight. We therefore propose, horizontal cylinder and the tank should be straight oblique type combination of round table body. The composition of the tank structure shown in Figure 1. Figure l Tank structure Ⅲ.The design of fluidized bedDetermine Determine the the the gas gas gas fluidized fluidized fluidized bed bed bed is is is designed designed designed for for for unloading unloading unloading of of of bulk bulk bulk cement cement cement truck truck truck key key key technology. technology. technology. Design Design Design goal goal goal is is is to to to improve improve improve the the discharge efficiency, reduce tank dead zone, lower residual rate. Fluidized bed gasification bed by the inclined baffle components, end of support board assembly, composed of compression bars and screws.1. Oblique baffle 2. Legislative panel 3. Bracket 4. Gasification board 5. Lateral 6. Countersunk head screws Figure 2 Oblique baffle component architecture 1. The choice of gasification board Gasification fluidized board is to ensure delivery of cement to meet the important parts, arrangement should be adopted when the block layout. At present, gasification panel are used in our soft, and commonly used are cotton canvas and polyester canvas. Breathable cotton canvas which is good, but easy to damp, sewage plug, so that permeability variation. As the cotton canvas and then rough surface, the remaining material will rise after discharge. Polyester, polyvinyl alcohol and other chemical fiber fabric is not easily wet, smooth etc, but the residual rate of electrostatic effects.2. Oblique baffle component design and calculation Oblique baffle design, pay attention to consider reducing the dead zone of cement delivery process, consider the oblique baffle and tank wall welded airtight. To this end, we have designed to improve the structure of helical baffle component shown in Figure 2. Inside the tank, not only vertical oblique angled baffle. Horizontal plane is also tilted, so it and the tank complex internal cross-island line. line. Accurately Accurately Accurately calculate calculate calculate the the the oblique oblique oblique baffle baffle baffle size. size. size. Material Material Material can can can be cut be cut off off to to to facilitate the facilitate the success success of of of workers, workers, workers, making making making welding welding welding firm, to firm, to ensure airtight performance.First set up the design space equation and the oblique baffle tank space equation, application of computer calculated the intersection, which was inclined baffle size. Figure 3 shows the internal structure of the tank Figure 3 The internal structure of the tankⅣ.Tank volume and load calculationAfter After investigation investigation investigation we we we found found found that that that most most most of of of the the the unloading unloading unloading of of of bulk bulk bulk cement cement cement truck truck truck gas gas gas tank tank tank is is is too too too large large large effective effective effective volume, volume, volume, that that that is, is, is, the the quality of the tank to carry more than the rated load weight. This may be because the designer take into account the angle of repose as cement loading of cement in the jar can not be filled, it may meet the user's desire to want to be able to multi-loading, but there are two important reasons:1. Cement density greater than lt / m. JB3971 JB3971 • • 1 "g as as unloading unloading of bulk bulk cement cement cement tank tank car car technology" technology" technology" specified; specified; "tank's "tank's effective effective effective volume, volume, volume, in in order to cement density lt / m. Calculated:V = G／r After our testing, cement density of 1.28t / m, so by lt / m. To calculate the effective volume of exposure on the big difference, it easy to overload. For example, the design of a car containing quality 10t, most manufacturers will be effective volume of the tank is designed to l1.5m, Akira car drivers before and after using the method will be filled with cement, thus installed 14.72t, overload too much.2. The lack of precise calculation of the effective volume As the complexity of the internal structure of the tank, in fact, estimate the volume of calculation is often simplified, the results of large deviations.粉粒物料运输车罐体设计附录B（中文翻译）摘要：摘要：本文讨论了粉粒物料运输车罐体结构形状的确定，流态化床的设计，介绍了罐体容积与载重量的计算方法。

附录AThe Design of Pull Arm Garbage Truck1The introduction of Pull Arm Garbage TruckPull arm garbage truck is equipped with two types of chassis that has a trunk load and unloading functions to pull arm device-specific vehicles. It can be achieved with car trunk the combination and separation, while the bulk of the trunk to achieve self-unloading cargo operations. The model has been widely used in foreign countries, often in the domestic industry as a sanitation refuse collection vehicles. 5 t pull arm garbage truck is one of the commonly used models, compared to 8 t Arm pull over large tonnage trucks, the pull-arm device structure is relatively simple and easy to domestic Manufacturers; And large tonnage often imported pull arm device. Domestic Manufacturers producing 5 t pull the car pulling the boom arm structure of the device, although about the same, but the important structural parameters of the selection and design of different structural arrangement, it will directly affect the car performance]20[.2 Pull the boom structure and principle of the device2.1 The structural characteristics of pull-arm device5 t pull arm garbage truck pulling device consists of pulling the boom arm and pull arm cylinder, the United Moving frame, trunk insurance hook and cylinder, and the frame. La Boom device structural arrangement shown in figure 2, pull telescopic arm is not used right-angle bend structure. the end of the cylinder and pull the piston rod side arm hinged on the hinge pivot B; Another linkage frame front end and hinged at the hinge pivot C, the formation of a rotary arm pull heart. Cylinder head cylinder arm pull side hinged front frame on the hinge pivot A; linkage frame hinged rear axle frame rear hinge pivot D, the formation of linkage rotary frame heart. Insurance linkage trunk rack hook set the hook cylinder and insurance cylinder.2.2 The working principle of the device arm pullPulling garbage truck arm by pulling the device to complete the function of two different dynamic, for boxes and dumping. When the pull device for boom box action, the first cylinder insurance hook action open the trunk insurance hook, trunk lift insurance. Pull lift arm cylinder piston rod elongation from the pull arm, pull arm to pivot around the hinge C clockwise rotation, the hook arm to pull back move. If the frame is equipped with a trunk, the trunk was pushed home ground. When put on the frame, so that the first hook retractor trunk rings, and contraction of the piston rod, pull arm to hinge pivot counter-clockwise rotation axis C, will put on the flat trunk, the insurance cylinder hook action, pull carriagesinsurance hook fixed to the frame to the trunk.When the pull-arm device dumping action, and action for different box, trunk insurance hook dump in the whole process to ensure that tension in the arm and trunk are not isolated, that is pull arm、the linkage through the trunk rack and trunk link between the insurance as one of the hook, by the deputy rear frame hinge pivot clockwise rotation axis D, lifting carriages lifted until the refuse rubbish. Trunk reset, as long as the retraction of cylinder piston rod pull arm, the pulling arm body still hinge pivot point D is the shaft counterclockwise rotation, until the trunk reset.3 La Boom Selection and design of device structure parameters3.1 Device to pull the boom pivot hinge arrangement and geometry of the main structureDetermined by the following three areas:a. Arm by pulling a dump truck performance, it is 5 t pull the best selection of cars from the arm unloading chassis, the chassis can be selected according to the length of pull arm device to determine frame the total length. To ensure the car to pull arm for changing trunk and dumping action by the force of the chassis reasonable and complete the dumping arm pull action pivot hinge rotation axis D of the location should be arranged in behind the rear spring plate from the chassis rear bearing axis, the spacing is about 0 ~ 100 mm.b. According to the first hinge pivot D arm pull for me the beginning of the selected pivot hinge rotation axis C. In the design and production of the actual process of pulling the car arm in arm had appeared during the pull action although the initial state, pull arm lift carriages, failed to pull arm pivot around the hinge C rotation, but with the linkage frame with the rotation around the hinge pivot point D, which can not get trunk open the beginning of fall; when lifting a certain height, the action of gravity in the trunk, the hinge will pivot C a sudden fall, so pull arm, the linkage frame and carriages suddenly drop, resulting in relatively large; in hit, resulting in extremely unsafe for me a smooth action. To resolve this problem, determine the hinge point C of the axis position is especially important. First the one hand, the horizontal axis of pivot C can not above the level layout of pivot D. In addition, by the hinge can pivot C stress analysis know, the hinge pivot axis of C must be below the level of tension hinge pivot arm cylinder head horizontal axis, while the hook arm pull-start action must be arranged in the vertical axis of the hinge pivot between C and the hinge pivot left foot.c. Important geometrical parameters arm pull a pull arm foot radius of gyration for pull the oil boom turning radius of the cylinder piston rod end of radius of gyration of the angle between the two radius. From the above points analysis we know that, The smaller of radius. The greater the force needed to pull the smaller cylinder arm. Meet the requirements underthe premise of arms-for-me pull-foot turning radius, the smaller the better, La boom cylinder rod side radius of gyration R. The bigger the better as far as possible, so that can pull compact boom, operating small space]21[.3.2 The selection of pull arm cylinder and cylinder installation angle y. The range ofDetermined by the following two aspects:a. By mapping method or analytical method to determine the location of the above the hinge pivot and Pull arm geometry and other components, may initially determine the pull-stroke arm cylinder and installation distance.b. Pull arm cylinder mounting angle of La Boom is the important structural parameters of devices. By the former knowledge, pull the boom box or device for carrying out the process of dumping action, pull the oil boom cylinders have to be overcome trunk (full load) resistance torque generated by gravity, and the lifting crane action start unloading boxes when the moment of resistance is the greatest moment of resistance to overcome, and in Boom began pulling action of the hinge pivot device static friction and inertia moment of resistance Maximum torque. So pull arm cylinder mounting angle y. From the previous analysis we know, when angle larger, the pull arm cylinder smaller maximum thrust required, select the pull arm cylinder bore can be smaller.By pulling in the boom cylinder is installed between the frame and trunk floor, oil cylinder installation layout space is limited, so the pull arm cylinder mounting angle range is also very limited. Design principles to children as much as possible to install a large angle, choose the right drawing arm oil pulling arm cylinder bore to meet performance requirements for the use of vehicles, without increasing the cost and fuel tank weight, and easy layout. Analysis and comparison of some domestic manufacturers to produce 5 t pull arm ,the actual design and production of cars and trucks pulling arm experience, 5 t pull arm around the installation space vehicles between 250 ~ 300 mm, the general tension arm cylinder mounting angle should be Taken between 3°~5°.附录B拉臂式垃圾车设计1拉臂车概述拉臂式垃圾车是在二类汽车底盘上装有使车箱具有装载和卸载功能的拉臂架装置的专用汽车。
