因为果树的枝、花、果密度不同、作业人员的熟练程度不同，所以果园作业人员的作业速度不是恒定值，那么配套的自走式作业机械就需要能在一个比较慢的行走速度上根据实际需要进行无极调速。当一个农场作业完毕到另一个农场转场时，作业机械又需要比较快的速度，以节省中转时间。而目前果园的自走式机械还没有这样的调速系统。
实用新型内容
本实用新型针对不足，提供一种让果园机械能在田间作业慢速行走时，可以进行无极调速以适应作业人员的生产速度，在转场时又可以使用快速档无级可调的较高速度行走转场的综合调速系统。
本实用新型解决上述技术问题的技术方案如下：一种植保机械的综合调速行走系统，包括发动机、V带轮、换向箱、联轴器、前驱动桥、传动轴、前桥传动轴、机械变速箱、后桥传动轴、后驱动桥、HST，所述发动机的输出端与所述V带轮的输入端连接，所述V带轮的输出端与所述换向箱的输入端连接，所述换向箱的输出端与所述HST的输入端连接，所述HST可以无极变速，所述HST的输出端与所述机械变速箱的输入端连接,可以对各个档位有级变速，再进行无级变速,最终实现综合调速，所述机械变速箱设有前后两个输出端，所述前输出端与所述驱动前桥连接，所述后输出端与后驱动桥连接。
在上述技术方案的基础上，本实用新型还可以做如下改进。
进一步，所述HST包括变量柱塞泵和液压马达，所述变量柱塞泵的轴为所述机械变速箱的输入端，所述液压马达的轴为机械变速箱的输出端。
进一步，所述换向箱的输出端通过联轴器+传动轴+联轴器的连接方式传递到HST的输入端。
进一步，所述后驱动桥的两端分别设有并行的两个车轮，所述的前驱动桥的两端分别设有一个车轮。
进一步，所述的车轮呈人字形花纹。
本实用新型的有益效果是：HST可以无极变速，HST与机械变速箱连接，对各个档位有级变速，再进行无级变速,最终实现综合调速，能满足果园作业时的慢速可调和较高速度转场的要求，提高果园作业人员的工作效率，且节约转场时间。
