Problems solved by technology

However, since it is an oil cylinder that drives the lifting arm to rotate around the frame, the force of raising and lowering the implement is completely borne by the oil cylinder, so the size of the oil cylinder will be much larger than that of the balance cylinder (because the balance cylinder

Abstract

The invention discloses a double-balanced oil cylinder transverse horizontal control device which comprises a rack, a left lifting arm, a left lifting oil cylinder, a left lifting pull rod, a lower left pull rod, a lower right pull rod, a right lifting pull rod, a right lifting arm, a right lifting oil cylinder, an upper pull rod, a first magnetic exchange valve, a second magnetic exchange valve, an angle transducer and an automatic horizontal controller. According to the double-balanced oil cylinder transverse horizontal control device, the two lifting arms are driven by the two lifting oil cylinders to rotate, due to the fact that the two lifting oil cylinders are adopted, a tractor suspension device can adopt hydraulic lifting oil cylinders with smaller cylinder diameter, and the manufacturing cost is reduced; meanwhile, the two lifting oil cylinders simultaneously control the horizontal state of a suspended farm implement, and the horizontal adjustment speed of the farm implement is higher.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a lateral level control device for double-balanced oil cylinders. Background technique [0002] Agricultural tillage and land preparation machinery often keep the implements suspended by the tractor in a horizontal state to keep the surface of the plowed land flat, to ensure the same emergence rate during sowing, or to maintain the same depth of transplanted seedlings in the soil. The current tractor hitching farm tool system basically adopts a three-point suspension device, which uses a hydraulic cylinder to drive the left and right lifting arms to rotate around the frame at the same time, and the left and right pull rods are driven by the left and right lifting rods to rotate, so as to realize the purpose of lifting the farm tool. This mechanism consolidates the tractor and the suspended agricultural implements together, and the left and right swings of the tractor when walking drive t...
