Abstract
The utility model discloses a hydraulic assembly of a wood grinder. The hydraulic assembly comprises a hydraulic oil chamber, a hydraulic motor, a hydraulic pump, a diverter valve and a hand-operated direction valve, wherein the hydraulic pump is communicated with the hydraulic oil chamber through a first oil way, the diverter valve is respectively communicated with the hydraulic oil chamber through a third oil way, the hand-operated direction valve through a fourth oil way, and the hydraulic pump through a fifth oil way, and the hand-operated direction valve is communicated with the hydraulic motor through a sixth oil way and a second oil way and communicated with the oil chamber through a seventh oil way. According to the hydraulic assembly of the wood grinder, operation stability of the hydraulic motor is improved, and functions of forward rotation and reverse rotation of the hydraulic motor are achieved.
Description
Technical field
The utility model relates to a kind of hydraulic pressure assembly of hog.
Background technique
At present, the hydraulic pressure assembly of traditional hog has hydraulic oil container, oil hydraulic motor and oil hydraulic pump conventionally, hydraulic oil container provides hydraulic oil, oil hydraulic pump drives oil hydraulic motor to rotate in hydraulic oil, this hydraulic pressure assembly shortcoming is: hydraulic oil can be excessive through oil hydraulic pump effect rear oil duct pressure, and the temperature of hydraulic oil also can increase, thereby make oil hydraulic motor fluctuation of service, and this hydraulic pressure assembly can only drive oil hydraulic motor to do forward and stop motion, cannot realize oil hydraulic motor reverse function.
Model utility content
The purpose of this utility model is to provide a kind of stability that improves oil hydraulic motor operation, realizes the hydraulic pressure assembly of the hog that rotates and reverse function of oil hydraulic motor.
The technological scheme that realizes above-mentioned purpose is: a kind of hydraulic pressure assembly of hog, comprise hydraulic oil container, oil hydraulic motor and oil hydraulic pump, oil hydraulic pump is communicated with by the first oil circuit with hydraulic oil container, also comprise diverter valve and hand-operated direction valve, diverter valve is communicated with hydraulic oil container by the 3rd oil circuit, and be communicated with hand-operated direction valve by the 4th oil circuit, also be communicated with oil hydraulic pump by the 5th oil circuit, hand-operated direction valve is communicated with oil hydraulic motor by the 6th oil circuit and the second oil circuit, and is communicated with hydraulic oil container by the 7th oil circuit.
Described diverter valve is fixedly connected with oil hydraulic pump by diverter valve fitting seat.
Described selector valve is fixedly connected with oil hydraulic pump by selector valve fitting seat.
In described hydraulic oil container, be also provided with oil filter.
Adopt after the structure of technique scheme, owing to also comprising diverter valve and hand-operated direction valve, diverter valve is communicated with hydraulic oil container by the 3rd oil circuit, and be communicated with hand-operated direction valve by the 4th oil circuit, also be communicated with oil hydraulic pump by the 5th oil circuit, hand-operated direction valve is communicated with oil hydraulic motor by the 6th oil circuit and the second oil circuit, and be communicated with hydraulic oil container by the 7th oil circuit, therefore hydraulic oil enters diverter valve from hydraulic oil container via the oil hydraulic pump running up, be divided into working oil and pressure release oil through diverter valve, pressure release oil is through the direct hydraulic return fuel tank of the 3rd oil circuit, can effectively reduce oil circuit pressure, reduce hydraulic oil temperature, working oil flows to oil hydraulic motor through hand-operated direction valve again, the running of promotion oil hydraulic motor, thereby improve the stability of oil hydraulic motor operation.And hand-operated direction valve can adjust by handle the flow direction of hydraulic oil, increase oil hydraulic motor and rotated and reverse function.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view in Fig. 1.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, 2, a kind of hydraulic pressure assembly of hog, comprise hydraulic oil container 1, oil hydraulic motor 2 and oil hydraulic pump 3, oil hydraulic pump 3 is communicated with by the first oil circuit 4 with hydraulic oil container 1, also comprise diverter valve 6 and hand-operated direction valve 7, diverter valve 6 is communicated with hydraulic oil container 1 by the 3rd oil circuit 8, and be communicated with hand-operated direction valve 7 by the 4th oil circuit 9, also be communicated with oil hydraulic pump 3 by the 5th oil circuit 10, hand-operated direction valve 7 is communicated with oil hydraulic motor 2 by the 6th oil circuit 11 and the second oil circuit 15, and is communicated with hydraulic oil container 1 by the 7th oil circuit 12.
Shown in Figure 1, in order to comprise diverter valve 6 and hand-operated direction valve 7 fixations, described diverter valve 6 is fixedly connected with oil hydraulic pump 3 by diverter valve fitting seat 13.Described selector valve 7 is fixedly connected with oil hydraulic pump 3 by selector valve fitting seat 14.
Shown in Figure 1, for filtered fluid force feed, in described hydraulic oil container 1, be also provided with oil filter 1-1.
Referring to Fig. 1, shown in 2, when the utility model uses, hydraulic oil passes through the first oil circuit 4 from hydraulic oil container 1, enter diverter valve 6 via the oil hydraulic pump 3 running up by the 5th oil circuit 10, due to the effect of oil hydraulic pump 3 and oil hydraulic motor 2, the temperature and pressure of hydraulic oil is improved in capital, therefore hydraulic oil can be divided into working oil and pressure release oil through diverter valve 6, if the pressure in hydraulic oil is excessive or oil temperature is too high, the valve open of diverter valve 6 by part hydraulic oil through the direct hydraulic return fuel tank 1 of the 3rd oil circuit 8, carry out pressure release and cooling, can effectively reduce oil circuit pressure, reduce hydraulic oil temperature, working oil enters hand-operated direction valve 7 by the 4th oil circuit 9 again, then flow to oil hydraulic motor 2 by the second oil circuit 15, promote oil hydraulic motor 2 runnings and drive hog work, thereby improve the stability that oil hydraulic motor 2 moves.And hand-operated direction valve 7 can adjust by reversing handle the flow direction of hydraulic oil, increase oil hydraulic motor 2 and rotated and reverse function.Working oil returns to hand-operated direction valve 7 from oil hydraulic motor by the 6th oil circuit 11, then by the 7th oil circuit 12 hydraulic return fuel tanks 1.
