Description
Technical Field
The utility model relates to a rearmounted traction hydraulic pressure balancing unit of agricultural machine.
Background
At present, when a tractor is used for cultivating farmland, due to the fact that the rear-mounted traction lifting hydraulic system of the tractor is influenced by different regional soils, the left lifting cylinder and the right lifting cylinder are different in bearing force, the left lifting cylinder and the right lifting cylinder are easy to unbalance load, oil cylinder pressure relief and oil seepage are caused, the system is light in operation, the lifting can be carried out during empty load, heavy load is often jumped up and down, the clamping is not free, the lifting is not in place, and the spring cultivation seeding and soil preparation effects are seriously influenced.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned shortcoming, provide a hydraulic pressure balancing unit is pull to rearmounted, it has mainly been solved the tractor rearmounted and has been pull promotion hydraulic system when the farmland is tilled, owing to receive the different influence of region soil, it is different to control the promotion jar bearing capacity, promotes the jar unbalance loading about appearing easily, causes hydro-cylinder pressure release and oil impregnate, light when the system operation, can promote during the empty load, run-out about the heavy load often appears, promote the phenomenon scheduling problem that does not target in place. The utility model aims at realizing like this, a rearmounted traction hydraulic pressure balancing unit by: the oil pump is composed of an oil tank, a filter, an oil pump, a hydraulic one-way valve, a cone valve, an energy accumulator, an electromagnetic directional valve, a left lifting cylinder, a right lifting cylinder, an overflow valve, a pressure cylinder, a straight-through one-way valve and a position adjusting control valve. The oil tank is internally provided with a filter, one end of the filter is connected with the oil tank, the other end of the filter is connected with an oil pump, the oil pump is respectively connected with a positioning control valve and a hydraulic control one-way valve, the hydraulic control one-way valve is respectively connected with an energy accumulator and a cone valve, the cone valve is respectively connected with an electromagnetic directional valve and a pressure cylinder, the pressure cylinder is respectively connected with a straight-through one-way valve, an overflow valve and a left lifting cylinder and a right lifting cylinder, and the left lifting cylinder and the right lifting cylinder are connected with the electromagnetic directional valve. This product simple structure, reasonable in design has adopted the turbocharging system, application accumulator and pressurized cylinder have improved the lifting speed, do not block during the promotion, energy loss has been reduced, because when cultivating the soil influence, control and promote the unbalance loading, the energy is unbalanced, cause the unbalanced problem of unbalance loading, the stationarity of operation has been guaranteed, the cone valve and check valve combination use have been adopted, it is sealed effectual, the switching-over impact force is little, can realize that hydraulic pressure switches on and off, the gliding pressure release of lifter, the oil leak have been avoided, the working property is reliable, high operating efficiency.

Detailed Description
The best embodiment of the invention is described in detail below with reference to the drawings, and the rear traction hydraulic balancing device comprises: the device comprises an oil tank 1, a filter 2, a filter 3, an oil pump 4, a hydraulic one-way valve 5, a cone valve 6, an energy accumulator 7, an electromagnetic directional valve 8, a left lifting cylinder and a right lifting cylinder 9, an overflow valve 10, a pressure cylinder 11, a straight-through one-way valve 12 and a position adjusting control valve 13. The oil tank 1 is internally provided with a filter 2, one end of the filter 3 is connected with the oil tank 1, the other end of the filter is connected with an oil pump 4, the oil pump 4 is respectively connected with a positioning control valve 13 and a hydraulic control one-way valve 5, the hydraulic control one-way valve 5 is respectively connected with an energy accumulator 7 and a cone valve 6, the cone valve 6 is respectively connected with an electromagnetic directional valve 8 and a pressure cylinder 11, the pressure cylinder 11 is respectively connected with a straight-through one-way valve 12, an overflow valve 10 and left and right lifting cylinders 9, and the left and right lifting cylinders 9 are connected with the electromagnetic directional valve 8.
The working principle is as follows: the hydraulic system uses liquid as working medium, because the liquid has incompressible property, it can transmit the pressure intensity in one place to each point and each direction in the container, after the oil pump 4 operates, the oil pump 4 continuously sucks oil from the oil tank 1 through the filter 3, when the oil pump 4 and the left and right lifting cylinders 9 are in a closed state, the oil pump 4 changes the mechanical energy transmitted by the engine into the pressure energy of working pressure and uniformly transmits the pressure energy to the distributor in the oil path and the lower cavity in the oil cylinder, the pressure energy of the working oil pressure in the oil cylinder is converted into the mechanical energy for pushing the piston and driving the suspension structure to lift the farm implement, thereby ensuring that the farm implement is lifted in place and not blocked during lifting, the oil port is sealed by the cone core by the cone valve 6, the oil discharge pressure is brought by the long-term abrasion of the sealing ring, the lifting arm is ensured not to buffer and descend when heavy load is carried out, the pressure cylinder 11 relieves the resistance or pressure of high farmland, when the farmland meets the pressure, the gas compresses and stores energy, when the lifting arm meets the pressure, the liquid is discharged and the liquid is smoothly expanded, thereby ensuring that the liquid is lifted cylinder smoothly and the farmland returns.
