The invention discloses an unmanned agricultural machine steering system. The system comprises a steering oil cylinder, a reversing solenoid valve, a solenoid valve control module and a processor, andfurther comprises a motor control module, a servo motor, an oil filter, a hydraulic oil tank and a gear pump, wherein an input end of the motor control module is electrically connected with an outputend of the processor, an output end of the motor control module is electrically connected with an input end of the servo motor, an output end of the servo motor is electrically connected with an input end of the gear pump, an output end of the hydraulic oil tank is connected with an input end of the gear pump; specific operation steps of the steering system are as follows, S1) receiving a steering command, and then entering a S2); and S2) judging whether an instruction angle value is received or not, if so, entering a S3), if not, returning to the S1) to wait for a steering command. The unmanned agricultural machine steering system achieves the effect of a proportional valve through cooperation of a servo motor and a gear pump, so steering control is more accurate, cost is low, the systemstructure is simplified, and maintenance is convenient.

    本发明公开了一种无人农机转向系统,包括转向油缸,换向电磁阀、电磁阀控制模块和处理器,还包括电机控制模块、伺服电机、滤油器、液压油箱和齿轮泵,所述电机控制模块的输入端与处理器的输出端电连接,电机控制模块的输出端与伺服电机的输入端电连接,伺服电机的输出端与齿轮泵的输入端电连接,液压油箱的输出端与齿轮泵的输入端连接,所述转向系统的具体操作步骤如下:S1):接收转向命令,然后进入到步骤2;S2):判断是否接收到指令角度值,如果是则进入步骤3,如果否则返回步骤1等待转向命令;本无人农机转向系统通过伺服电机和齿轮泵的配合达到比例阀的效果,使得转向控制更为精确,且成本低,简化了系统结构,便于维护。
