摘要 针对我国华北地区玉米种植整个生长周期玉米病虫害及不同区域玉米种植行距不同的植保问题,设计开发了一款自走式高地隙底盘可调节喷雾机。该喷雾机可通过调节底盘地隙高低与轮距,满足应玉米在不同生长阶段的药物喷洒及不同区域玉米行距的需求。通过SolidWorks进行整车关键部件三维建模,经喷雾机的稳定性理论计算分析后再对行驶工况进行Adams稳定性仿真分析,结果表明:横向行驶时侧倾角为29.40°,符合车辆设计横向侧翻稳定性要求。 Aiming at the plant protection problem of maize diseases and insect pests in different areas of North China before and during the middle and late period of small pieces of maize planting,and the problem that the growth height of maize is greatly different in different periods and the row spacing of maize planting in different plots is different,a selfpropelled highland gap chassis adjustable sprayer was designed and developed.The machine can realize the function of four-wheel drive and four-wheel steering,which can adjust the height and height of the chassis and the width and width of the wheel base during the plant protection operation.The SolidWorks is used to conduct three-dimensional modeling of the vehicle.Then,the stability of the sprayer is theoretically calculated and analyzed.Finally,through ADAMS stability simulation analysis,the stability of lateral running is obtained.
