摘　　要：针对目前丘陵坡地中缺少适用灌溉机械现状,结合茶园种植特点及丘陵坡地的地形特征,设计了一种适用于丘陵坡地的自走式喷洒装置.对喷洒装置直线行驶、纵向爬坡及横向坡行走等常见喷洒行驶工况进行力学理论分析.采用RecurDyn多体动力学软件对装置进行建模,对常见喷洒行驶工况的装置行驶状态进行仿真分析,仿真结果表明,装置具有良好的直线行驶及爬坡性能,能顺利通过最大15°横向斜坡、最大15°纵向斜坡.研制出样机并进行了真机试验,实测样机平均行驶速度1.94 km/h,具有良好的直线行驶性能,行驶偏移率2.88%;且平稳通过坡角为13°纵向坡,并在坡度范围为8°~13°的横向坡安全稳定行驶,与仿真结果相符,满足自行走喷洒装置的坡地作业要求,为后续丘陵灌溉装备的设计提供了参考.In response to the current lack of suitable irrigation machinery in hilly slopes,a self-propelled spraying device suitable for hilly slopes was designed based on the characteristics of tea plantation planting and the terrain features of hilly slopes.Mechanical theoretical analysis on common spraying driving conditions such as straight-line driving,longitudinal climbing,and lateral slope walking of the spraying device were performed.The RecurDyn multibody dynamics software was used to model the device and simulate the driving state of the device under common spraying driving conditions.The simulation results show that the device has good straight-line driving and climbing performance,and can smoothly pass through a maximum 15°transverse slope and a maximum 15°longitudinal slope.A prototype was developed and tested on a real machine.The average driving speed of the prototype was mea-sured to be 1.94 km/h,with good straight-line performance,and a driving deviation rate of 2.88%.It smoothly passes through a longitudinal slope with a slope angle of 13°,and safely and stably travels on a transverse slope with a slope range of 8°-13°,which is consistent with the simulation results and meets the requirements for slope operation of self-propelled spraying devices.This provides a reference for the design and research of subsequent hilly irrigation equipment.
