The invention discloses an electromagnetic control hydraulic steering switching device for plant protection machinery. The electromagnetic control hydraulic steering switching device comprises a hydraulic device and an electrical device. The hydraulic device is controlled by the electrical device to realize three steering modes of two-wheel steering, four-wheel steering and oblique movement, so that the trafficability of the machine is greatly improved, and the machine can adapt to more and more complex terrains. A purely-sealed meso-position sensor system is used, left deviation, right deviation and meso-position can be detected, and simplicity and reliability are achieved. The hydraulic lock is additionally arranged on the rear wheel steering oil cylinder, so that the stability of the rear wheel steering oil cylinder is guaranteed, pressure relief of the rear wheel steering oil cylinder is prevented, and deviation of rear wheels is avoided. The rear wheel steering oil cylinder is additionally provided with the middle position sensor, and when the rear wheel and the front wheel are not on the same rail, the middle position can return automatically. The electric solenoid valve combination is used for achieving three steering modes, and is simple, convenient, durable, reliable, convenient to maintain and low in price.

    本发明公开了一种植保机械用电磁控制液压转向切换装置,包括液压装置和电气装置。通过电气装置控制液压装置实现二轮、四轮、斜行三种转向方式,大大的提高了机器的通过性,可以适应更多更复杂的地形。使用纯密封中位传感器系统,可以检测左偏、右偏以及中位,简单可靠。后轮转向油缸增加液压锁,从而保证了后轮转向油缸的稳定性,防止后轮转向油缸泄压,避免了后轮的偏移。后轮转向油缸增加有中位传感器,当后轮与前轮不同轨时,可以自动回归中位。采用电气电磁阀组合用于实现三种转向方式,简单方便,耐用可靠,方便维修,价格便宜。
