Abstract
The utility model discloses a four in one bucket wheel loader hydraulic system, a serial communication port, including the gear pump, the entrance point of gear pump and hydraulic tank intercommunication, the multiple unit valve is connected to the exit end of gear pump, and the multiple unit valve is looped in through balanced valve connection hydro -cylinder, and the multiple unit valve still communicates with hydraulic tank. The utility model discloses on having hydraulic system, increase the balanced valve of establishing ties, realize the effective control to the four in one bucket. This hydraulic control system uses in the loader design, can prevent the hydro -cylinder vacuum production through the effect of balanced valve to avoid the four in one bucket to open automatically, guarantee that the machine is effective, the safety work.
Description
Technical field
This utility model is related to a kind of four in one bucket hydraulic system for wheel loader, belongs to loader technical field.
Background technology
At present, configure the loader of four in one bucket, its hydraulic control system is generally from the 3rd realization control of banked direction control valves
System, in four in one bucket quick acting, easily vacuum to this control mode in oil cylinder, when scraper bowl is in discharge position, by
In scraper bowl deadweight, can automatically open, impact loader work, bring potential safety hazard simultaneously.
Utility model content
To be solved in the utility model is the problem that when existing hydraulic system uses, vacuum easily in oil cylinder.
In order to solve problem above, this utility model provides a kind of four in one bucket hydraulic system for wheel loader, and it is special
Levy and be, including gear pump, the entrance point of gear pump is connected with hydraulic oil container, the port of export of gear pump connects banked direction control valves, multichannel
Valve connects oil cylinder by balanced valve and forms loop, and banked direction control valves is also connected with hydraulic oil container；Suck through gear pump from hydraulic oil container
Fluid enters banked direction control valves, and fluid is eventually returned to hydraulic oil container.
Preferably, it is respectively provided with a cleaner between described gear pump, banked direction control valves and hydraulic oil container.
The utility model has the advantages that：In existing hydraulic system, increase by one balanced valve of series connection, realize four-in-one is shoveled
The effective control of bucket.This hydraulic control system is applied in loader design, can prevent oil cylinder shape by the effect of balanced valve
Become vacuum, thus avoid four in one bucket automatically to open it is ensured that machine effectively, trouble free service.
Brief description
The schematic diagram of the four in one bucket hydraulic system for wheel loader that Fig. 1 provides for this utility model.
Specific embodiment
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figure 1, for the schematic diagram of four in one bucket hydraulic system for wheel loader, the wheeled dress of described four in one bucket
Carrier aircraft hydraulic system includes gear pump 3, from the fluid that hydraulic oil container 1 sucks after cleaner 1 filtration, enters banked direction control valves 4,
Banked direction control valves 4 connecting balanced valve 5, balanced valve 5 connects oil cylinder 6, and the fluid of hydraulic circuit returns to hydraulic oil container 1 through cleaner 27,
Form hydraulic control system.
This hydraulic control system is applied on wheel loader, can pass through the effect of balanced valve 5, prevent oil cylinder 6 from being formed
Vacuum, thus avoid four in one bucket automatically to open it is ensured that machine effectively, trouble free service.
