The invention relates to a steering valve group for a tractor, which comprises an oil pumping structure, an electric control steering valve group, a steering gear and a steering cylinder, the oil pumping structure is communicated with the electric control steering valve group through a pipeline, the steering gear is connected with a steering column of a steering wheel, and the steering cylinder is connected with a steering shaft of a vehicle body wheel. And the electric control steering valve group is respectively communicated with the steering gear and the steering cylinder through pipelines. The electric control steering valve set and the steering gear are connected and matched with each other, pressure oil pumped out by the oil pumping structure is subjected to opening and closing selection according to different working condition requirements, and therefore the steering cylinder is controlled to move leftwards or rightwards in a manual mode or an unmanned mode, and the tractor is controlled to turn rightwards or leftwards.

    本发明涉及一种拖拉机用转向阀组,包括泵油结构、电控转向阀组、转向器和转向缸,所述泵油结构通过管路与所述电控转向阀组连通,所述转向器与方向盘的转向柱连接,所述转向缸与车体车轮的转向轴连接,所述电控转向阀组分别与所述转向器和转向缸通过管路连通。通过电控转向阀组与转向器相互连接并配合,将泵油结构泵出的压力油根据不同的工况需求,进行开闭选择,从而控制转向缸能够在人为模式或者无人模式下,进行左移或者右移,从而控制拖拉机进行右转或者左转。
