农用履带车喷洒系统的设计 摘要 我国是一个农业大国，农业是主要的生产生活方式之一，农民种植农作物，喷洒农药是一项必不可少的工作。农作物病虫害扩散迅速，病虫种类多，并且会有过度繁殖，爆发成灾害的风险。病虫害会严重影响农作物生产，给农民造成巨大损失，严重影响我国的国民经济发展。因此，为有效抗击病虫害，提高农作物生产质量和生产效率和农药喷洒效率，必须喷洒农药抵制害虫，减少农作物的减产。 本课题研究一种农用履带车的喷洒系统，采用无线遥控控制农用履带车的行走、喷洒。喷药箱容量大，喷药范围广。采用高压柱塞泵连接高压管连接接头以及不锈钢万向喷头，设置万向节可以调节喷头角度，选取不同型号的喷头使喷洒范围更广更全面。在此基础上，考虑到果树之间距离不一，另配置电动推杆可以调整喷头距离，大范围喷洒农药，提高喷洒效率。 关键词：柱塞泵；不锈钢万向喷头；电动推杆 英文摘要 Desig
