盘刀式茎秆切碎机设计
DESIGN OF DISC CUTTER STALK SHAREDDER
摘要
本次设计主要是以国内的秸秆作为参考，通过分析秸秆构成成分，设计出适合国内使用的切碎机，能耗低、碎稳定为优点的茎秆切碎机。为我国农业科研技术贡献一份力量。
根据对以往的切碎机的研究和总结，分析出过去切碎机的优点与不足，对切碎机的整体进行设计，传送方案的选择，动力资源的合理配比，各大机构的尺寸参数等进行比较和计算，做出了详细的说明。
该机主要是由切碎器、变速箱和喂入机构、喂入槽、甩抛装置、带传动、电动机组成。其原理是秸秆由喂入槽喂入，在喂入机构作用下将其压实并卷入机构，被动定刀片组成的切碎器切碎，最后由抛送装置抛出机外。
关键词：秸秆，切碎机，喂入槽，动定刀片。
Abstract
This design is mainly based on the domestic straw as a reference, by analyzing the composition of straw, designed for domestic use chopper, low energy consumption, broken stability as the advantages of the stem shredder. For China's agricultural science and technology to contribute a force.
According to the research and summarization of the previous chopper, the advantages and disadvantages of the chopper are analyzed, the whole design of the chopper, the selection of the transmission scheme, the reasonable proportion of the dynamic resources, the size parameters of the major institutions Such as comparison and calculation, made a detailed description.
The machine is mainly composed of chopper, gearbox and feeding mechanism, feeding slot, throwing device, belt drive, motor composition. The principle is that the straw is fed by the feed tank, under the action of the feeding mechanism to be compacted and involved in the mechanism, the chopper composed of the passive blade chopped, and finally by the throwing device out of the machine.
Keywords: Straw, chopper, feed slot, move the blade.
