Embodiment Construction

[0011] Such as figure 1 As shown, the hydraulic operating system includes an oil tank 1, an oil pump 2, a multi-way valve 3, a first oil cylinder 4, a second oil cylinder 5, a first switch 6, and a second switch 7. The oil tank 1 is connected to the oil pump 2, and the oil pump 2 is connected to the multi-way valve The multi-way valve 3 is connected to the first oil cylinder 4 through the first switch 6, the multi-way valve 3 is connected to the second oil cylinder 5, the second oil cylinder 5 is connected to the first oil cylinder 4 through the second switch 7, and the multi-way Valve 3 is also directly connected to tank 1 .

[0012] The hydraulic oil in the hydraulic oil tank 1 outputs high-pressure oil through the oil pump 2 and is delivered to the multi-way valve 3 . Initial oil supply: the first switch 6 and the second switch 7 are turned on, and the direction of the hydraulic oil is: oil tank 1—oil pump 2—(manually open) multi-way valve 3—the lower end of the first oil ...

Abstract

The invention discloses a single handle tandem type hydraulic operation system of a sloping field hand tractor. The hydraulic operation system comprises an oil tank, an oil pump, a multiway valve, a first oil cylinder, a second oil cylinder, a first switch and a second switch, wherein the oil tank is connected with the oil pump; the oil pump is connected with the multiway valve; the multiway valve is connected with the first oil cylinder through the first switch, and is also connected with the second oil cylinder; the second oil cylinder is connected with the first oil cylinder through the second switch; and the multiway valve is directly connected with the oil tank. By using the structure, the lifting of the left and right wheels of the tractor can be finished through a single handle, the structure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to a hydraulic operating system, in particular to a single-handle series hydraulic operating system suitable for slope-field walking tractors. Background technique [0002] The hydraulic operating system is an important part of the slope lifting walking tractor to complete the lifting action. At present, the double-handle hydraulic system is widely used. The double-handle hydraulic system is independent of the two oil cylinders. The piston connecting rod of the side cylinder shortens and the tractor tire goes up; loosen the handle, and the left cylinder is in a locked state; when the right handle is pushed to the rising position, the piston rod of the right cylinder is extended, and the tractor tire goes down; when it is hit to the falling position, the right side The piston connecting rod of the oil cylinder shortens the tractor tire and rises; release the handle, and the right oil cylinder is in a locked state. Compared with ...
