The height-adjustable hydraulic agricultural chassis comprises a chassis body, an engine is fixedly connected to the front side of the upper end of the chassis body, a hydraulic pump is fixedly connected to the rear side of the upper end of the chassis body, fixing frames are fixedly connected to the four corners of the chassis body correspondingly, and driving assemblies are arranged at the bottom ends of the fixing frames correspondingly. The height of the chassis body is adjusted through the four hydraulic cylinders, each hydraulic cylinder adjusts one walking wheel, the telescopic amount of the hydraulic cylinder is adjusted, the levelness of the chassis body can be adjusted, each hydraulic cylinder is controlled through one reversing valve, and the four hydraulic motors provide advancing power and are connected with the speed reducer to reduce the speed. The flow pressure of each hydraulic motor is controlled by one reversing valve, the arranged hydraulic shock absorber can play a role in buffering and shock absorption, the steering angle of the driving assembly can be adjusted through the arranged steering assembly, and steering, turning around and transverse movement in a narrow space can be achieved conveniently.
本发明公开了可调节高度的液压农用底盘,包括底盘主体,所述底盘主体上端前侧固定连接有发动机,所述底盘主体上端后侧固定连接有液压泵,所述底盘主体四角处均固定连接有固定架,所述固定架底端均设置有驱动组件。本发明中,通过四个液压缸来调节底盘主体的高度,每个液压缸调节一个行走轮,调节液压缸的伸缩量,可以调节底盘主体的水平度,且每个液压缸用一个换向阀控制,通过四个液压马达提供前进动力,连接减速器降低速度,每个液压马达流量压力各用一个换向阀控制,设置的液压减震器可以起到缓冲减震的作用,通过设置的转向组件可以对驱动组件的转向角度调节,便于实现狭小空间的转向、掉头和横向移动。
