12马力手扶拖拉机配套旋耕机改进设计

Improvement Design of 12-horsepower Walking Tractor Supporting Rotary Tiller

我国手扶拖拉机面广量大,与其配套的旋耕机大多是老式产品,耕幅窄,功耗高,性能较差。近些年来,随着科技的进步,出现了一系列宽幅旋耕机、破垡盖籽机和旋耕播种机等,改善了旋耕机的性能和增加了旋耕机的用途,但这些旋耕机参数各异,功能单一,仍存在一定缺陷。本文设计一种多功能宽幅旋耕机,是在老式旋耕机的基础上改进设计而成,结构优化。通过不同形式的拆装,能够实现旋耕、破垡、埋青灭茬和播种施肥等多项作业。

Walking tractor, covering a wide range and large demand in china, has affiliated traditional rotary tiller which shows its disadvantages as narrow-width, high-power and poor performance, As technology progresses, recent years there have appeared a series of wide-width rotary tiller, clod-crushing and seed-coveting machine , and cultivator-seeder etc. which improve the performance and increase usefulness of the rotary tiller. But these rotary tillers still ba~,e disadvantages such as different parameters and simple-funtion.A multifunctional wide-width rotary tiller designed by the author optimizes the struetufe of the traditional rotary tiller in order to do the work as rotary tillage,clods-crushing and seed-covering,stubble- ploughing various processes.
