Abstract
A hydraulic control system for a weed-cutting launch comprises a parallel gear oil pump, two groups of multiway reversing valves, a dividing valve, an adjustable throttle, a two-way hydraulic lock, and a execute component, wherein two oil discharge openings of the parallel gear oil pump are connected with an oil inlet P of each group of multiway reversing valve respectively; an oil inlet of the execute component is connected with a one-way throttle or a two-way hydraulic lock; an oil discharge opening A of one group of multiway reversing valve is connected with the dividing valve; the other group of multiway reversing valve is connected with the one-way throttle directly; the execute component is a hydraulic motor or a difunctional hydrocylinder. The hydraulic control system realizes complex mechanical transmission of the weed-cutting launch, so that the weed-cutting launch is simple and compact in overall structure and stable in transmission, can realize integrated operation of cutting, transporting, and recycling in water and achieve the purpose of eliminating excess float grass, and fully embodies simplicity of the overall machine.
Description
Affiliated technical field
The utility model relates to the hydraulic control system of weed-cutting launch in a kind of water
Background technique
At present, on market, in general water, the driving mechanism of weed-cutting launch is all that machinery is controlled the kind of drive, the source of power and the design of mechanism are very complicated, will make like this feature dimension and the weight of weed-cutting launch in water strengthen, cause the manufacture cost of equipment higher, simultaneously just higher to operator quality requirement, be difficult to realize the simple, intelligent of weed-cutting launch.
Summary of the invention
The utility model technical issues that need to address are the above-mentioned deficiencies that overcome prior art, a kind of hydraulic control system of weed-cutting launch is provided, replace mechanism driving mode complicated and changeable, make in water the mechanism of weed-cutting launch simple, compact, during work, stable action, speed is adjustable, performance is more safe and reliable.
The technological scheme that the utility model adopts is: a kind of hydraulic control system of weed-cutting launch, two oil drain outs of combination gear oil pump are connected with the oil inlet P of every group of multiple directional control valve respectively, filler opening at executive component has connected one-way throttle valve or bidirectional hydraulic lock, wherein one group of multiple directional control valve oil drain out A be connected with diverter valve, and another group multiple directional control valve be directly connected with one-way throttle valve.
Second major character of the present utility model is: executive component is oil hydraulic motor or double-act-ing hydraulic J-Horner.
The beneficial effects of the utility model are: in water, weed-cutting launch has been installed a set of hydraulic control system, solved the mechanical transmission of weed-cutting launch complexity, make that whole type is simple in structure, compact, stable drive, can in water, realize cutting, conveying, reclaim institutional operation mode simultaneously, can reach the object of removing unnecessary pasture and water, fully demonstrate easy.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Figure is hydraulic control system schematic diagram of the present utility model
In figure, 1, combination gear oil pump, 2, multiple directional control valve, 3, diverter valve, 4, delivery hydraulic pressure motor, 5, one-way throttle valve, 6, cutting liquid pressure motor, 7, two-way cylinder, 8, bidirectional hydraulic lock, 9, road wheel oil hydraulic motor.
Embodiment
In the drawings, two groups of multiple directional control valves (2), one group of multiple directional control valve (2) is controlled the walking of weed-cutting launch, and another group multiple directional control valve (2) is controlled the lifting of cutting, conveying and the ceding of Taiwan of weed-cutting launch.During work, under the effect of combination gear oil pump (1), hydraulic oil is supplied with respectively to two control unit multiple directional control valves (2), wherein each multiple directional control valve (2) is comprised of two-part oil circuit, part oil circuit passes through respectively one-way throttle valve (5) by diverter valve (3) and is diverted to cutting liquid pressure motor (6) and delivery hydraulic pressure motor (4), finally get back to fuel tank assembly, and another part oil circuit is controlled two two-way cylinders (7) through bidirectional hydraulic lock (8).Two oil circuits of another one multiple directional control valve pass through respectively one-way throttle valve (5) and control respectively two road wheel oil hydraulic motors (9).
Claims (2)
1. the hydraulic control system of a weed-cutting launch, comprise: combination gear oil pump, two groups of multiple directional control valves, diverter valve, adjustable restrictive valve, bidirectional hydraulic lock and executive components, it is characterized in that: two oil drain outs of combination gear oil pump are connected with the oil inlet P of every group of multiple directional control valve respectively, filler opening at executive component has connected one-way throttle valve or bidirectional hydraulic lock, wherein one group of multiple directional control valve oil drain out A be connected with diverter valve, and another group multiple directional control valve be directly connected with one-way throttle valve.
2. according to the hydraulic control system of a kind of weed-cutting launch claimed in claim 1, it is characterized in that: executive component is oil hydraulic motor or double-act-ing hydraulic J-Horner.
