摘要

本研究以马铃薯等根茎物料为研究对象，通过对根茎物料特性的分析，确定切碎原理和方法，设计出动力消耗低、力度大小满足切碎成型要求的根茎切碎机。推动我国目前综合开发利用农作物根茎物料资源的技术创新和实际应用。

通过对原始数据的分析、方案的论证比较和有关数据的分析计算，主要完成了切碎机的总体设计，电动机的选择以及传动方案的分析、比较与选择等内容。在此基础上对切碎机机体的结构尺寸、驱动转轴的结构尺寸、V带传动等设计应用价值进行了详细的计算和说明。

该机主要是由切碎机和喂入机构、喂入槽、甩抛装置、带传动、电动机组成。其原理是根茎物料由喂入槽喂入，在喂入机构作用下将其压实并卷入机构。被动刀片组成的切碎器切碎，最后由抛送装置抛出机外。

Abstract

In this study, potato and other root material for the study, by the material properties of the roots of analysis to determine the principles and methods of shredding designed low power consumption, efforts to meet the size requirements for compression molding roots shredder. Promote the comprehensive development and utilization of China's current crop roots material resources of technological innovation and practical application.

Through the analysis of raw data, analysis and calculation demonstrate Comparison Programme and the relevant data, mainly to complete the overall design of the shredder, the analysis of the motor and drive program selection, comparison and selection and so on. On this basis, the structure of the shredder body size, the drive shaft structure size, V belt drive, such as design value calculation and detailed description.

This machine is mainly composed of a shredder and feeding mechanism, feeding trough, throwing throwing unit, belt drive, motor. The principle is that the material from the feeding trough feeding roots, in effect compacting the feed mechanism and the involvement of institutions. Passive fixed chopper blades consisting of chopped, and finally by throwing device thrown outside.

Keywords: disc cutter, shredder, roots materials, feed trough, throwing machine
