Description
Technical field
The present invention relates to a kind of straw baler, particularly relate to a kind of straw baler hydraulic system.
Background technology
Straw baler belongs to a kind of packing compression device, and by light weight, the straw compression stacking space big is readily transported together, and straw is remaining part after crops harvesting, and existing straw processing mode mainly has: 1, burn, and pollutes environment, wastes resource；2, harvester packing, by straw bundling during harvester harvesting, but this packing is loose, and volume is little, still needs to again process, is unfavorable for the recycling of resource；3, baling press packing, once packing can reach 1 ton, convenient transport, utilizes resource recycling.Existing straw baler uses hydraulic system to meet the once required energy provided of packing weight, but the hydraulic system of existing baling press exists work continuously and causes overheated and shut down, and list hydraulic stem is to problems such as the compression of straw are not in place.
Summary of the invention
It is an object of the invention to solve problem present in current techniques, it is provided that a kind of can the most normally work, support the straw baler hydraulic system of multiple spot compression.
For reaching above-mentioned purpose, the technology used in the present invention means are: a kind of straw baler hydraulic system, the main oil pump including hydraulic oil container and being arranged on hydraulic oil container and auxiliary oil pump, main oil pump passes through main oil pump unloading electromagnetic valve, electromagnetic relief valve, check valve, auxiliary oil pump is connected jointly by auxiliary oil pump unloading electromagnetic valve promotes mainly hydraulic stem electro-hydraulic reversing valve to promoting mainly hydraulic stem fuel feeding, after reaching to set pressure, main oil pump unloading electromagnetic valve off-load；Main oil pump connects enabling hydraulic stem electro-hydraulic reversing valve, is promoting mainly after hydraulic stem quits work, and main oil pump unloading electromagnetic valve is closed, main oil pump by enabling hydraulic stem electro-hydraulic reversing valve to enabling hydraulic stem fuel feeding, auxiliary oil pump unloading electromagnetic valve off-load；Auxiliary oil pump connects out-feed liquid depression bar electro-hydraulic reversing valve, and auxiliary oil pump unloading electromagnetic valve is closed, and auxiliary oil pump is out-feed liquid depression bar fuel feeding by out-feed liquid depression bar electro-hydraulic reversing valve.
Further, promote mainly described in and be provided with overflow valve at hydraulic stem electro-hydraulic reversing valve, enabling hydraulic stem electro-hydraulic reversing valve, out-feed liquid depression bar electro-hydraulic reversing valve oil-in.
The beneficial effects of the present invention is: by main oil pump and auxiliary oil pump hydraulic circuit so that master hydraulic bar energy Fast Compression, while improving work efficiency, prevent high oil temperature；The enabling hydraulic stem electro-hydraulic reversing valve increased and out-feed liquid depression bar electro-hydraulic reversing valve, provide a kind of new mode of operation for straw baler.
Accompanying drawing explanation
The present invention is further elaborated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure: 1, hydraulic oil container, 2, main oil pump, 3, auxiliary oil pump, 4, main oil pump unloading electromagnetic valve, 5, electromagnetic relief valve, 6, check valve, 7, auxiliary oil pump unloading electromagnetic valve, 8, promote mainly hydraulic stem electro-hydraulic reversing valve, 9, enabling hydraulic stem electro-hydraulic reversing valve, 10, out-feed liquid depression bar electro-hydraulic reversing valve, 11, overflow valve.
Detailed description of the invention
A kind of straw baler hydraulic system as shown in Figure 1, the main oil pump 2 including hydraulic oil container 1 and being arranged on hydraulic oil container and auxiliary oil pump 3, main oil pump 2 is by main oil pump unloading electromagnetic valve 4, electromagnetic relief valve 5, check valve 6, auxiliary oil pump 3 is connected jointly by auxiliary oil pump unloading electromagnetic valve 7 promotes mainly hydraulic stem electro-hydraulic reversing valve 8 to promoting mainly hydraulic stem fuel feeding, after reaching to set pressure, main oil pump unloading electromagnetic valve 4 off-load；Main oil pump 2 connects enabling hydraulic stem electro-hydraulic reversing valve 9, is promoting mainly after hydraulic stem quits work, and main oil pump unloading electromagnetic valve 4 is closed, and main oil pump 2 gives enabling hydraulic stem fuel feeding, auxiliary oil pump unloading electromagnetic valve 7 off-load by enabling hydraulic stem electro-hydraulic reversing valve 9；Auxiliary oil pump 3 connects out-feed liquid depression bar electro-hydraulic reversing valve 10, and auxiliary oil pump unloading electromagnetic valve 7 is closed, and auxiliary oil pump 3 is out-feed liquid depression bar fuel feeding by out-feed liquid depression bar electro-hydraulic reversing valve 10.
Described promoting mainly is provided with overflow valve 11 at hydraulic stem electro-hydraulic reversing valve 8, enabling hydraulic stem electro-hydraulic reversing valve 9, out-feed liquid depression bar electro-hydraulic reversing valve 10 oil-in.
This hydraulic system is for a kind of straw baler, this straw baler includes feeding mechanism, main compressor structure, discharging mechanism, hydraulic system, power set, main compressor structure includes compression bin, be arranged on one end in compression bin promotes mainly hydraulic stem, with promote mainly the compression plate that hydraulic stem is connected, compression bin correspondence compression plate the other end close；Discharging mechanism includes the enabling hydraulic stem that out-feed liquid depression bar that reclaiming plate is connected, discharge door are connected with discharge door with reclaiming plate, and reclaiming plate is separately mounted to the two sides of compression bin blind end vertical with promoting mainly hydraulic stem with discharge door；Hydraulic system connects promotes mainly hydraulic stem, out-feed liquid depression bar, enabling hydraulic stem；Power set connect feeding mechanism and hydraulic system.
Auxiliary oil pump is high-pressure pump, at main oil pump and auxiliary oil pump cooperation to when setting pressure, main oil pump unloading electromagnetic valve off-load, auxiliary oil pump continues to work independently for promoting mainly hydraulic stem fuel feeding, stopping until promoting mainly after hydraulic stem reaches to set pressure, the straw baler serviced due to this hydraulic system realizes repeatedly having extruded a bag, therefore, this kind of fuel system works quickly, will not produce high temperature, and squeezing effect is good；To be extruded complete a bag after, main oil pump unloading electromagnetic valve close, main oil pump by enabling hydraulic stem electro-hydraulic reversing valve to enabling hydraulic stem fuel feeding, now auxiliary oil pump by auxiliary oil pump unloading electromagnetic valve off-load oil return to fuel tank；After enabling completes, auxiliary oil pump unloading electromagnetic valve is closed, and out-feed liquid depression bar electro-hydraulic reversing valve is opened for out-feed liquid depression bar fuel feeding.
Application embodiment is only intended to technical characteristic disclosed in the present application is described, those skilled in the art, by simply replacing the change carried out, still fall within the scope that the application is protected.
