摘要
对高速插秧机全液压底盘驱动系统进行设计,在保证现有插秧机作业质量的前提下,采用全液压驱动方式实现无极变速,提高功率密度、平顺性和布置灵活性,为后期智能化和自动化提供平台。全液压底盘驱动系统采用单泵四马达的闭式液压系统,使用分流阀防止打滑,并进行了水田滑转率测量试验,根据相关参数计算液压系统压力、流量以及排量,并对液压泵和马达进行选型,结合其效率曲线保证液压泵工作在高效区间。该设计方法对其他行走机械液压底盘的设计具有一定的参考价值。
The driving system of hydraulic chassis of high-speed rice transplanter is designed. Under the premise of ensuring work quality, the designed chassis adopt whole hydraulic driving system in order to change speed continuously, enhance power density, and improve layout flexibility. This chassis also can provide a platform of intelligence and automation. The close cycle system of single pump and four motors is designed in the driving system. The flow divider valve is used to prevent slipping. The slip rate measurement in paddy field is conducted for the more precise calculation results. The kinds of hydraulic pumps and motors are se- lected according to the calculated pressure, flux and displacement for ensuring that the pump works in its efficient speed range. The project has some significance for designing hydraulic chassis of other machineries.
