根据水稻插秧及设计要求,设计了水稻插秧机液压控制系统,主要包括液压底盘驱动系统及液压转向系统。驱动系统采用单泵四马达,防滑阀组防止并联液压马达打滑;液压转向系统采用单向稳定转向阀,依据作业要求对液压系统的关键零部件进行参数计算。在AMESim中对所设计的液压驱动系统和转向系统进行了仿真,对水稻插秧机中的压力、流量及扭矩等参数进行仿真模拟,验证水稻插秧机液压系统的可行性与可靠性,通过田间试验测定水稻插秧机在田间工作时的驱动阻力和平均滑移率。研究结果表明:插秧机在水田中运行稳定、操作灵活,设计方案可推广到其他类型的农业机械,对液压系统在农业机械工程中的应用具有重要指导意义。

According to rice transplanting and design requirements,design the rice transplanter hydraulic control system,which mainly includes hydraulic chassis drive system and hydraulic steering system.The driving system adopts a single pump and four motors,the anti-skid valve group prevents the parallel hydraulic motors from slipping,and the hydraulic steering system adopts a one-way stable steering valve.The parameters of the key components of the hydraulic system are calculated according to the operating requirements.In AMESim,the designed hydraulic drive system and steering system were simulated,and the pressure,flow and torque parameters in the rice transplanter were simulated to verify the feasibility and reliability of the hydraulic system of the rice transplanter.Field experiments were carried out.Measure the driving resistance and average slip rate of rice transplanter when working in the field.The research results show that the machine runs stably and flexibly in paddy fields.The hydraulic chassis design proposed in this research can be extended to other types of agricultural machinery.The application of the system in agricultural machinery engineering has important guiding significance.
