The invention provides a logic controller, a hydraulic steering system and a movable platform, the logic controller comprises a first shuttle valve, a second shuttle valve and a third shuttle valve, one end of the first shuttle valve is used for connecting a working device control signal port of the movable platform, and the other end of the first shuttle valve is used for connecting an agricultural implement control signal port; one end of the second shuttle valve is used for being connected with a signal port of a manual steering gear, the other end of the second shuttle valve is used for being connected with a signal port of an automatic steering gear, a signal port of the first shuttle valve and a signal port of the second shuttle valve are connected to the two ends of the third shuttle valve respectively, and a signal port of the third shuttle valve is used for being connected with a signal port of the load-sensitive variable pump. The load-sensitive variable pump can adjust oil output in real time according to changes of hydraulic feedback signals, oil can be supplied according to needs, and the purpose of saving energy is achieved. The steering response speed of the tractor can be increased by adjusting the flow of the output oil, the operation experience of a user is guaranteed, and therefore the production efficiency is improved.
本申请提出一种逻辑控制器、液压转向系统及可移动平台,包括第一梭阀、第二梭阀以及第三梭阀,第一梭阀的一端用于连接可移动平台的工作装置控制信号口,第一梭阀的另一端用于连接农机具控制信号口,第二梭阀的一端用于连接手动转向器的信号口,第二梭阀的另一端用于连接自动转向器的信号口,第一梭阀的信号口和第二梭阀的信号口分别连接于第三梭阀的两端,第三梭阀的信号口用于连接负载敏感变量泵的信号口。载敏感变量泵可根据液压反馈信号变化实时调整油液输出,可做到按需供给油液,达到节能目的。通过调整油液输出的流量大小,可以提升拖拉机的转向响应速度,保障用户操作体验,从而提升生产效率。
