1、毕业设计说明书中文摘要全套设计,QQ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
2、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。关键词变速箱;秸秆粉碎机;甩刀;结构及工作原理-37-毕业设计说明书外文摘要ThehydrauliccylinderheaddrillingfixturedesignAbstractTheprotectioncultivationisthemostimportantintern
