Hydraulic control system of tractor suspension mechanism

Abstract

The invention relates to the technical field of tractor suspension, in particular to a hydraulic control system of a tractor suspension mechanism. The system comprises limiting rods, limiting sliding grooves are formed in the centers of the surfaces of the side walls of the two ends of the limiting rods, one end of the limiting rods is fixedly connected with a first limiting rod connecting lug, a limiting rod hinge hole is formed in the first limiting rod connecting lug, the other end of the limiting rods is fixedly connected with a second limiting rod connecting lug, and the top end of a buffer rod is fixedly connected with a second hinge seat. By arranging a screw rod, the limiting rods and a hydraulic lifting rod are arranged on the screw rod, and the positions of the limiting rods and the hydraulic lifting rod are adjusted through locking nuts, so that the distance between suspension mechanisms is adjusted, and the connection requirement for connection of agricultural tools such as ploughs of different sizes can be met. A stretching rod is arranged, the limiting rods are stabilized and damped through a third spring, and the two limiting rods draw close to each other, so that the plough is clamped and fixed, and the stability of fixing the plough is improved.

Description

technical field [0001] The invention relates to the technical field of tractor suspension, in particular to a hydraulic control system of a tractor suspension mechanism. Background technique [0002] The tractor suspension mechanism is the main device for the tractor to pull farm tools for agricultural operations. The suspension mechanism is the connecting rod between the farm tool and the tractor. Through the hydraulic connection rod, the lifting, lowering and working position adjustment of the farm tool can be realized. It is an essential part of the tractor. important components. [0003] However, due to the non-uniform size of the connecting parts of farm tools such as plow tools, the existing hydraulically controlled suspension mechanism cannot be reasonably adjusted according to the size of the farm tool to meet the connection requirements of different farm tools, and the traditional suspension mechanism has poor connection stability for farm tools. This further affec...

Problems solved by technology

[0003] However, due to the non-uniform size of the connecting parts of farm tools such as plow tools, the existing hydraulically controlled suspension mechanism cannot be reasonably adjusted according to the size of the farm tool to meet the connection requirements of different farm tools, and the traditional suspension mechanism has poor connection stability for farm tools. This further affects the working efficiency of farm tools such as plows on cultivated land. Therefore, the purpose of the present invention is a hydraulic control system for a tractor suspension mechanism to solve the problem that the existing suspension mechanism cannot be reasonably adjusted according to the size of the farm tool to meet the connection requirements of different farm tools. Moreover, the connection stability of traditional suspension mechanisms to farm tools is poor, which in turn affects the work efficiency of farm tools such as plows on cultivated land.
