Description
Technical field
This utility model belongs to the hydraulic control device of a cropper, is specifically related to the hydraulic control dress of blue or green feed harvester
Put.
Background technology
The kind of blue or green feed harvester tool is the most, towed, self-propelled, suspension type etc. can be divided into several 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, turns in field heavier during operation；
Self-propelled green grass or young crops raises machine work efficiency height, but expensive, and most of self-propelled green grass or young crops raises machine all from external import, and fittings supply is not
In time, after-sale service is not in place；It is little that suspension type green grass or young crops raises machine unit, moderate.
Due to, the grassland area of China is relatively big, and blue or green feed harvester in use there is also some problems.
Summary of the invention
This utility model is that the problem solving prior art existence proposes, and its objective is to provide the hydraulic pressure of blue or green feed harvester
Control device.
The technical solution of the utility model is: the hydraulic control device of blue or green feed harvester, including hydraulic package, and by liquid
Multiple stroke assemblies of pressure Component driver, described hydraulic package and No. I three-way electromagnetic valve, No. II three-way electromagnetic valve pipeline are even
Logical, described No. I three-way electromagnetic valve, No. II three-way electromagnetic valve are connected with corresponding stroke assembly, described hydraulic package bag
Oil scraper case, gear pump, be provided with filter at the inlet port of described gear pump, described Filter Precision is less than 32 μm.
Described filter is well strainer.
No. I described three-way electromagnetic valve, No. II three-way electromagnetic valve installation site are near hydraulic package.
Described No. I three-way electromagnetic valve, No. II be provided with return line between three-way electromagnetic valve and fuel tank.
Described return line is provided with return filter.
The filtering accuracy of described return filter is less than 18 μm.
This utility model machine system dependable performance and not consumption of engine power, and No. I three-way electromagnetic valve, No. II three
High-low pressure is distinguished by way solenoid valve, improves the service life of Hydraulic Elements.Reduce the loss of engine output, improve
Gear pump, three-way electromagnetic valve road valve, the service life of oil cylinder.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Wherein:
1 hydraulic package 2 I three-way electromagnetic valve
3 No. II three-way electromagnetic valves.
Detailed description of the invention
Hereinafter, with embodiment, this utility model is described in detail referring to the drawings:
As it is shown in figure 1, the hydraulic control device of blue or green feed harvester, it is characterised in that: include hydraulic package 1, and by liquid
Multiple stroke assemblies (not shown) that pressure assembly 1 drives, described hydraulic package 1 and 2, No. II three road electricity of No. I three-way electromagnetic valve
Magnet valve 3 pipeline connection, 2, No. II three-way electromagnetic valve 3 of No. I described three-way electromagnetic valve is connected with corresponding stroke assembly, described
Hydraulic package 1 include fuel tank, gear pump, be provided with filter at the inlet port of described gear pump, described filter essence
Degree is less than 32 μm.
Described filter is well strainer.
2, No. II three-way electromagnetic valve 3 installation site of No. I described three-way electromagnetic valve is near hydraulic package 1.It is thus possible to subtract
Few oil inlet and oil return back pressure, reduces impact and the air pocket of complete machine.
No. I described three-way electromagnetic valve 2, II is provided with return line between three-way electromagnetic valve 3 and fuel tank.
Described return line is provided with return filter.
The filtering accuracy of described return filter is less than 18 μm.
Described return filter is also well strainer.
2, No. II three-way electromagnetic valve 3 of No. I three-way electromagnetic valve in this utility model is fixed with seat board by bolt.
This utility model machine system dependable performance and not consumption of engine power, and No. I three-way electromagnetic valve, No. II three
High-low pressure is distinguished by way solenoid valve, improves the service life of Hydraulic Elements.Reduce the loss of engine output, improve
Gear pump, three-way electromagnetic valve road valve, the service life of oil cylinder.
