摘要：根據(jù)調(diào)查了解，現(xiàn)在農(nóng)村使用的小型青飼料切碎機大多都存在很多安全性隱患。據(jù)調(diào)查，在農(nóng)村因為操作青飼料切碎機不小心而導(dǎo)致手被切斷的悲劇一幕時有發(fā)生。為了避免這些安全事故的再次發(fā)生，本文設(shè)計了一種較安全的小型青飼料切碎機，該設(shè)計主要是在分析現(xiàn)有青飼料切碎機的結(jié)構(gòu)以及運動形式，找出其存在安全隱患的地方并對其進行改進設(shè)計，從而消除隱患，進而設(shè)計出一種新型的小型青飼料切碎機。

　　　本設(shè)計首先介紹了選題的目的及意義，闡述了青飼料切碎機的發(fā)展?fàn)顩r；然后對現(xiàn)有的青飼料切碎機進行分析，找到導(dǎo)致意外事故發(fā)生的原因，再針對這些隱患部位進行設(shè)計。

　　　論文的主題部分包括了送料裝置的方案設(shè)計、減速裝置的設(shè)計、偏置的曲柄滑塊結(jié)構(gòu)的設(shè)計、圓柱壓縮彈簧的設(shè)計以及整機的裝配；最后對本設(shè)計進行概括和總結(jié)，簡要說明本設(shè)計的優(yōu)點和不足。

Abstract：According to investigation know, now the small rural use email there are many green fodder most security hidden danger. According to the survey, in rural because operation green fodder to accidentally email hand cut off tragedy scene happen from time to tome. In order to avoid these safety accidents occur again, this paper designs a safer small green fodder in email, this design is mainly in the analysis of existing green fodder structure and email form of movement and find out the unsafe places and the improved design, so as to eliminate hidden dangers and then designs a new type of small email green fodder.

　　　This design first introduces the purpose and significance of the topic selection, this paper expounds the developing situation of the email green fodder; Then on to existing green fodder for division email.

　　　The topic of thesis part includes feed mechanism design, the design of the speed institutions, design of equipment, slider-crank structure design, cylindrical compression spring design and the assembly; Finally a this design, this paper Outlines the advantages and disadvantages of the design.

Keywords: email green fodder; Improved design; To remove the hidden danger.
