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
The present invention relates to a kind of hydraulic operating system, particularly relate to one and be applicable to hillside fields hand tractor monolever tandem hydraulic operation system.
Background technique
Hydraulic operating system is the important component part that hillside fields lifting hand tractor completes lifting action.At present, generally use dual-handle hydraulic system, dual-handle hydraulic system be two oil cylinders independently, left handle get to rise position, left side oil cylinder piston connecting rod extend, tractor tire decline; Get to the position fallen, left side oil cylinder piston connecting rod shortens tractor tire and rises; Release handle, left side oil cylinder is in the lock state; Right handles gets to the position risen, and right side oil cylinder piston connecting rod extends, and tractor tire declines; Get to the position fallen, right side oil cylinder piston connecting rod shortens tractor tire and rises; Release handle, right side oil cylinder is in the lock state.Compare with monolever hydraulic system: complex operation, left and right oil cylinder lifting time is long, and execution is slow, and waste time and energy, efficiency is low.
Summary of the invention
The object of the invention is to provide a kind of structure simple, easy to operate to prior art Problems existing, execution is fast, the hydraulic operating system that working efficiency is high.
The object of the invention is to be achieved through the following technical solutions, this hydraulic operating system comprises fuel tank, oil pump, multi-way valve, the first oil cylinder, the second oil cylinder, the first switch, second switch, described fuel tank is connected with oil pump, oil pump is connected with multi-way valve, described multi-way valve is connected with the first oil cylinder by the first switch, described multi-way valve is connected with the second oil cylinder, and described second oil cylinder is connected with the first oil cylinder by second switch, and described multi-way valve is also directly connected with fuel tank.
Working principle: the hydraulic oil of hydraulic oil container, exports high pressure oil by oil pump, is transported to multi-way valve.Initial fuel feeding: the first switch and second switch are opened, the trend of hydraulic oil is: fuel tank-oil pump--(manual unlocking) multi-way valve-the first oil cylinder lower end-the first switch-the first cylinder upper end-second switch-the second cylinder upper end, at this moment the second oil cylinder piston connecting rod extends under the promotion of high pressure oil, when the second oil cylinder piston connecting rod stretches out completely, hydraulic fluid pressure continues to keep, the first oil cylinder piston connecting rod is forced to extend, when the first oil cylinder piston has just started to extend, close the first switch, at this moment initialization completes, enter normal working, 1, when multi-way valve gets to the position of B, first oil cylinder piston connecting rod extends, second oil cylinder piston connecting rod shrinks, complete the left right side that rises of tractor and fall action, multi-way valve gets to the position of A, and the second oil cylinder piston connecting rod extends, and the first oil cylinder piston connecting rod shrinks, and completes the right left side that rises of tractor and falls action.Unclamp multi-way valve handle, multi-way valve is in closed position, and the first oil cylinder, the second oil cylinder all keep the state of release handle.
Beneficial effect of the present invention:
Structure is simple, easy to operate: handle is beaten left, and the first oil cylinder piston connecting rod extends, and the second oil cylinder piston connecting rod shortens, and completes tractor and is tilted to the right; Right side got to by handle, and the right oil cylinder piston connecting rod extends, and left side oil cylinder piston connecting rod shortens, and completes tractor and is tilted to the left; Handle unclamps (neutral position), and two oil cylinders are in the lock state.Compare with dual-handle hydraulic system: simple to operate, left and right oil cylinder lifting time is short, and execution is fast, alleviates labor intensity, improves operating efficiency.
Accompanying drawing explanation
Embodiments of the invention are described in detail below in conjunction with accompanying drawing
Fig. 1 is schematic diagram of the present invention
In figure: 1, fuel tank 2, oil pump 3, multi-way valve 4, first oil cylinder 5, second oil cylinder 6, first switch 7, second switch 8, second oil cylinder piston connecting rod 9, first oil cylinder piston connecting rod.
Embodiment
As shown in Figure 1, this hydraulic operating system comprises fuel tank 1, oil pump 2, multi-way valve 3, first oil cylinder 4, second oil cylinder 5, first switch 6, second switch 7, fuel tank 1 is connected with oil pump 2, oil pump 2 is connected with multi-way valve 3, multi-way valve 3 is connected with the first oil cylinder 4 by the first switch 6, multi-way valve 3 is connected with the second oil cylinder 5, and the second oil cylinder 5 is connected with the first oil cylinder 4 by second switch 7, and multi-way valve 3 is also directly connected with fuel tank 1.
The hydraulic oil of hydraulic oil container 1, exports high pressure oil by oil pump 2, is transported to multi-way valve 3.Initial fuel feeding: the first switch 6 and second switch 7 are opened, the trend of hydraulic oil is: fuel tank 1-oil pump 2--(manual unlocking) multi-way valve 3-the first oil cylinder 4 lower end-the first switch 6-the first oil cylinder 4 upper ends-second switch 7-the second oil cylinder 5 upper end, at this moment the second oil cylinder piston connecting rod 8 extends under the promotion of high pressure oil, when the second oil cylinder piston connecting rod 8 stretches out completely, hydraulic fluid pressure continues to keep, the first oil cylinder piston connecting rod 9 is forced to extend, when the first oil cylinder piston connecting rod 9 has just started to extend, close the first switch 6, at this moment initialization completes, enter normal working, 1, when multi-way valve gets to the position of B, first oil cylinder piston connecting rod 9 extends, second oil cylinder piston connecting rod 8 shrinks, complete the left right side that rises of tractor and fall action, multi-way valve gets to the position of A, and the second oil cylinder piston connecting rod 8 extends, and the first oil cylinder piston connecting rod 9 shrinks, and completes the right left side that rises of tractor and falls action.Unclamp multi-way valve handle, multi-way valve 3 is in closed position, and the first oil cylinder 4, second oil cylinder 5 all keeps the state of release handle.
