Description
Technical field
The invention belongs to a kind of hydraulic control device of cropper, and in particular to a kind of hydraulic control dress of blue or green feed harvester
Put.
Background technology
The species of blue or green feed harvester tool is relatively more, and it is several to be divided into towed, self-propelled, suspension type etc. by operating type.
Towed blue or green feed harvester is made up of main frame and ceding of Taiwan two parts, and unit is huge, is turned in field during operation heavier；
Self-propelled blue or green feeding machine operating efficiency is high but expensive, and most of self-propelled blue or green feeding machine, all from external import, fittings supply is not
In time, after-sale service is not in place；Suspension type green grass or young crops feeding machine unit is small, moderate.
Because the grassland area in China is larger, and blue or green feed harvester also be there are problems that in use.
The content of the invention
The present invention proposes that the purpose is to provide a kind of hydraulic pressure of blue or green feed harvester to solve the problems, such as that prior art is present
Control device.
The technical scheme is that：A kind of hydraulic control device of blue or green feed harvester, including hydraulic package, and by liquid
Multiple stroke components of Component driver are pressed, described hydraulic package connects with No. I three-way electromagnetic valve, No. II three-way electromagnetic valve pipeline
Lead to, No. I described three-way electromagnetic valve, No. II three-way electromagnetic valve are connected with corresponding stroke component, described hydraulic package bag
Fuel tank, gear pump are included, filter is provided with the inlet port of described gear pump, described Filter Precision is less than 32 μm.
Described filter is well strainer.
Described No. I three-way electromagnetic valve, No. II three-way electromagnetic valve installation site are close to hydraulic package.
Described No. I three-way electromagnetic valve, No. II return line is provided between three-way electromagnetic valve and fuel tank.
Return filter is provided with described return line.
The filtering accuracy of described return filter is less than 18 μm.
Machine system dependable performance of the present invention and not consumption of engine power, and No. I three-way electromagnetic valve, No. II three roads electricity
High-low pressure is given and distinguished by magnet valve, improves the service life of Hydraulic Elements.The loss of engine output is reduced, improves tooth
Wheel pump, three-way electromagnetic valve road valve, the service life of oil cylinder.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Wherein：
1 three-way electromagnetic valve of hydraulic package 2 I
3 No. II three-way electromagnetic valves.
Embodiment
Hereinafter, referring to the drawings and embodiment the present invention is described in detail：
A kind of as shown in figure 1, hydraulic control device of blue or green feed harvester, it is characterised in that：Including hydraulic package 1, and by liquid
