秸秆粉碎机的设计
摘 要 保护性耕作是国际农业技术发展的重要趋势,秸秆还田技术是机械化保护性耕作中关键的一项技术。使用机械化秸秆还田技术可以有效地解决农忙期间争农时、争劳力的矛盾,有力推动秸秆还田的农业全程机械化进程,避免由于焚烧秸秆产生的环境污染。本着一机多用、降低生产成本的原则,研制了既能满足玉米秸秆、又能单独实现旋耕作业的新型玉米秸秆还田机。
(1)在对秸秆粉碎及灭茬基本理论分析的基础上,提出多功能玉米秸秆还田机总体结构设计方案。采用卧式结构,主要由悬挂装置、变速箱、秸秆粉碎机构、等组成。拖拉机输出动力经万向节传递给变速箱,变速箱一轴经齿轮、链轮两级增速后,带动粉碎刀辊工作。
(2)设计了新型变速箱,实现了秸秆粉碎的作业,结构简单,一机多用。主要由锥齿轮传动等组成。利用从动齿轮的离合来实现粉碎、旋耕动力的分离与结合,从而分别完成秸秆粉碎与旋耕单项作业,实现一机多用之功能。

Abstract
The protection cultivation is the most important international agriculturaltechnology development smashed straw technology is one essential technology of the mechanized protection smashed straw machines call effectively solve the problems that striving for time and labour during the busying farming time,and Can make the agricultural entire also call avoid envkonment pollution caused by straw setting on to multi-function and reducing production COst,multi—function smashed straw machine WaS not only Can smash st“1w together with the stubble and put it back to the farmland to increase the nutrient once time but also Can according to Our practical necessityto choose rotary tilling single function.
(1)On the basic of studying the elementary theory of smaShing straw,the integral structure design plan ofmulti-functionmachine WaS introduced. The machine is posed of hanng system,gearbox,belttransmission system,stalk-soil returning roller,rotary tiller roller,and depth limit is transmitted from the tractor shaft to the power output shaft ofthe gearbox is acceleratedby both bevel gears and strap then it drives the stalk
—smashing knives revolving quickly. Another is moved by the bevel gears and strap wheel to drive the rotary tiller working.
(2)The innovativepoint is the design of new gearbox,which has realized
