摘　　要：针对现有果园风送式喷雾机难以满足果树对不同喷雾高度的要求,设计了一种新型果园风送式喷雾机传动系统。该传动系统由拖拉机后置动力输出驱动,基于对象设计的理念,采用一体式后传动箱实现两个离心式风机反向旋转,通过旋转改变导流风箱的位置实现变高度喷雾。运用PRO/E软件建立三维模型,并运用ANSYS软件对传动系统中高速旋转轴进行了模态分析,结果显示结构设计合理,满足果树对不同喷雾高度的要求。According as the existing air-assisted sprayer does not meet the requirement of different orchard about the height of changeable aerosol, this paper designs a new orchard air-assisted sprayer transmission system. The transmission system is driven by the tractor rear PTO, based on the concept of object design, chooses integrated after gearbox to realize the two centrifugal fan reverse rotation , the height of the spray can be changed by adjusting the angle of guide shell. Af-ter the completion of the design calculations using PRO/E software to create three-dimensional model, and the high-speed rotating shaft modal analysis using the ANSYS software, the results show that structural is designed reasonable and meets the requirements.
