Description
Technical field
The utility model relates to a kind of hydraulic control device, is a kind of double-action hydraulic distributor specifically.
Background technique
According to tractor engine hydraulic operation mode, current domestic 25-50 horsepower range tractor hydraulic handles point single-acting and two large classes fall by force in strong liter, wherein single-acting distributor is board-like connection with lifter, space is little, reliable in structure, but along with the double-action distributor that generally requires in the current agricultural machinery and implement of user's requirement to use strong liter to fall by force, double-action distributor can replace single-acting gradually and become the main flow in market, at present in 25-50 horsepower range, double-action distributor is all that tubular type connects, take up room large, hydraulic system does not have board-like reliable from structure.
Summary of the invention
The purpose of this utility model is to provide a kind of compact structure, rationally distributed double-action hydraulic distributor, realizes and being connected with the board-like of hydraulic jack, take up room little, reliability is strong.
The utility model for the technological scheme that technical solution problem adopts is:
Double-action hydraulic distributor described in the utility model comprises valve body, is arranged on the guiding valve in valve body, valve body is provided with high-pressure oil pipe interface, the first oil circuit interface, the second oil circuit interface, described the first oil circuit interface, the second oil circuit interface are communicated with high-pressure oil pipe interface by guiding valve respectively, the outer surface of described guiding valve is provided with the first annular groove, the second annular groove, described high-pressure oil pipe interface is arranged on the lower end of valve body, the first oil circuit interface and the second oil circuit interface are arranged on the side of valve body, and the end face of the first oil circuit interface and the second oil circuit interface is in the same plane.
One end of described valve body is fixedly connected with box body, in described box body, is fitted with control lever shaft, and described control lever shaft is vertical with guiding valve to be arranged, and is installed with connecting rod on control lever shaft, and the end of described connecting rod and guiding valve is hinged, and the end of control lever shaft connects operating handle.
Owing to having adopted said structure, this double-action hydraulic dispensing arrangement compactness, rationally distributed, can realize and direct board-like connection of hydraulic jack, take up room little, reliability is strong.

Embodiment
As shown in Figure 1, double-action hydraulic distributor described in the utility model comprises valve body 2, is arranged on the guiding valve 3 in valve body 2, valve body 2 is provided with high-pressure oil pipe interface 1, the first oil circuit interface A, the second oil circuit interface B, described the first oil circuit interface A, the second oil circuit interface B are communicated with high-pressure oil pipe interface 1 by guiding valve 3 respectively, the outer surface of described guiding valve 3 is provided with the first annular groove 32, the second annular groove 31, in the time that guiding valve 3 slides to the right, on guiding valve 3, first annular groove 32 on the right is connected the first oil circuit interface A and high-pressure oil pipe interface 1; In the time that guiding valve 3 slides to the left, on guiding valve 3, second annular groove 31 on the left side is connected the second oil circuit interface B and high-pressure oil pipe interface 1, and in the time that guiding valve 3 is positioned at neutral position, high-pressure oil pipe interface 1 is communicated with the drainback passage T on guiding valve 3.Described high-pressure oil pipe interface 1 is arranged on the lower end of valve body 2, and the first oil circuit interface A and the second oil circuit interface B are arranged on the side of valve body 2, and the end face of the first oil circuit interface A and the second oil circuit interface B is in the same plane.
As shown in Figure 2, one end of described valve body 2 is fixedly connected with box body 4, in described box body 4, is fitted with control lever shaft 41, the setting vertical with guiding valve 3 of described control lever shaft 41, on control lever shaft 41, be installed with connecting rod 42, described connecting rod 42 is hinged with the end of guiding valve 3, and the end of control lever shaft 41 connects operating handle 43.
As shown in Figure 3, Figure 4, what the first oil circuit interface A in valve body 2 and the second oil circuit interface B, drainback passage T adopted with lifter housing 6 is board-like connection, realizing valve body by bolt 5 is connected with lifter housing, being different from present tubular type connects, not only saved oil pipe, reliability is greatly improved.
When use, operating principle is as follows:
Action one, the high pressure oil that gear pump produces enters valve body 2 by high-pressure oil pipe 1, when operating handle 43 is got to raised position to the right, control lever shaft 41 rotates, be with movable pulley 3 to move right by connecting rod 42, hydraulic oil enters operating cylinder by the first annular groove 32, the first oil circuit interface A, thereby makes oil cylinder carry out the action promoting; Action two, get to lowering position left when operating handle 43, control lever shaft 41 rotates, and is with movable pulley 3 to be moved to the left by connecting rod 42, hydraulic oil enters operating cylinder by the second annular groove 31, the second oil circuit interface B, thereby make oil cylinder carry out decline action; Action three, in the time that operating handle 43 is in neutral position, system mesohigh oil returns to fuel tank by the drainback passage T in guiding valve 3.
