基于插秧机的悬挂式喷杆喷雾机的设计 摘要 20世纪以来，针对农作物田间喷药工作的需求，设计了一种基于插秧机的喷杆喷雾设计，对喷杆的升降机构，喷杆，喷雾水路系统等关键的零部件和系统等进行了研究和设计，水稻作为中国主要的粮食作物之一，在食作物中占有极其重要的地位。在种植水稻过程时，传统插秧机只能完成插秧工作，而不能完成喷洒农药的喷雾工作。 喷杆喷雾机是应用最广的植物保护机具。其向大功率高地隙喷宽幅的方向发展，和有效提高机器的作用效率，降低作业时对作物的损害，传统喷杆喷雾机采用机械式喷杆结构。在田间喷雾及道路转移时，外部刺激会使喷杆产生剧烈振动，尤其是在相同的喷杆固定固有频率的条件下，风干与外部振动频率相吻和严重影响喷雾质量，并且传统喷杆喷雾机使用，不能完成多项工作。针对上述问题，结合农作物种植模式和植保名义要求，综合考虑工作效率，吃药均匀度以及普遍适用性等关键要素，本文通过查阅国内外参考资料将理论分析计算机虚拟优化设计，开展基于插秧机的喷杆喷雾设计优化设计及实验，以提高喷杆喷雾机和插秧机有效结合提高利用率的研究。 关键词：插秧机喷杆喷雾设计喷杆折叠装置喷杆系统 Abstract Si
