摘　　要：根据农户当地农艺要求确定中耕轮距2280 mm,计算基本型拖拉机配中耕胎的前后轮8种轮距,分别选取其中一种轮距,确定过渡法兰的长度,设计前后轮过渡法兰。通过前移前托架与前桥摆销支座配合的安装支座,增加拖拉机轴距,方便进行整机布置。前托架设置限位凸台和限位块,基本型和中耕型分别限制前桥摆角11°和8°。另外,分别对后处理、前桥传动轴、车门开启铰链、挡泥板和车梯踏板等部件进行优化改进。改进设计后的拖拉机可同时实现标准作业和中耕作业,农艺适应性强。According to the local agricultural requirement of farmers,2280 mm is determined for the intertillage wheel track.Eight kinds of front and rear wheel tracks of the basic tractor matched with row-crop tire are calculated.One of them is selected respectively to determine the length of the spacer flange and design the spacer flange for front and rear wheels.By moving forward the mounting support of front carrier matched with the front axle swing pin support,the tractor wheelbase is increased and the whole tractor layout is convenient.The front carrier is provided with a limit boss and a limit stop.The front axle swing angle is respectively limited to 11°and 8°in the basic type and the row-crop type.In addition,the rear treatment,front axle drive shaft,door opening hinge,fender,ladder pedal and other components are optimized and improved.The improved tractor can realize the standard operation and row-crop operation at the same time,and has strong agronomic adaptability.
