Description
Technical field
The utility model relates to grain header commonly used in the agricultural production, specifically is that a kind of stalk hinge of grain header is cut device.It is fit to the stalk hinge of wheat, paddy rice, corn, oil plant and other crops is cut.
Background technology
The ripe crops of tradition results rely on manually finishes, and has that labour intensity is big, efficient is low, delays deficiency such as farming season.Along with the development that science and technology is maked rapid progress, people have researched and developed grain header, and the farming that this has helped the peasant has to a great extent improved crop yield, has brought out and out economic benefit.
Existing grain header only has the function of results seed, and after their seed results with ripe crops, the harvesting equipment that the stalk of crops is for want of special-purpose can only be stayed on the field, treats that follow-up hand harvest removes.But in actual harvesting process, the stalk manual removal needs very big labour intensity, and efficient is extremely low, and is very consuming time, has a strong impact on follow-up farming, delays farming season.For this reason, most of peasant often takes the mode of " fire attack ", burning field stalk, with its removing, this effectively reduces labour intensity really, has also improved efficient, yet this has also brought new problem: stalk can not get reasonable utilization, serious waste of resources as broad-spectrum living resources; Discharge a large amount of dense smokes, contaminated environment behind the straw burning; Very easily breaking out of fire leads to major accident, the economic loss heaviness.
Along with the in succession appearance of local government to the burning straw ban, " fire attack " obtained effective containment.Simultaneously a lot of agricultural equipment manufacturing enterprises make great efforts the device that research and development are specially adapted for straw harvesting on the basis of grain header, also obtained comparatively desirable effect.At present, the straw harvesting device of commercially available grain header mainly is made of tool fixing frame and movable knife rack, movable knife rack is superimposed to be assemblied on the tool fixing frame, be fixed with blade in the same way on tool fixing frame and the movable knife rack respectively, on the chassis underbeam that the pole and the holder of tool fixing frame by both sides is fixed on the tracks of harvester place, movable knife rack is connected fork one end, the fork other end is connected with pendulum ring on the axostylus axostyle, pendulum ring and holder and the coaxial setting of driven sprocket, the driving mechanism of grain header drives and puts the gyration work when driving driven sprocket, and the pendulum ring moves before and after making fork, move on tool fixing frame thereby drive movable knife rack, realize harvesting stalk.The main deficiency of this device is: 1. pusher action industry before the fork, bump against barrier easily, and fork is hit bending deformation, cause the movable knife rack can't regular event, device is damaged; 2. the tool fixing frame fixed position is low excessively, and grain header is easy to generate card mud, twines careless phenomenon when farm work, and easy and ridge collision, makes whole reaping apparatus distortion, normal operation, the inconvenient maintenance of gathering in of influence.
Summary of the invention
The purpose of this utility model is: at above-mentioned the deficiencies in the prior art, provide a kind of stalk hinge of grain header to cut device, it has rational in infrastructure, easy to use and characteristics such as stubble-cleaning is effective.
The purpose of this utility model is achieved through the following technical solutions.
A kind of stalk hinge of grain header is cut device, comprise tool fixing frame and movable knife rack, be respectively equipped with blade on described tool fixing frame and the movable knife rack, movable knife rack is slidedly assemblied on the tool fixing frame, on putting the beams in place in the chassis that the pole and the holder of tool fixing frame by both sides is fixed on grain header, described movable knife rack is connected universal swing arm one end by connecting rod, universal swing arm is fixed on below tool fixing frame pole by bearing block and goes up on the support that is provided with, the other end of universal swing arm is connected universal arm shaft bearing with universal arm shaft bearing assembling, holder, the end and the driven sprocket of tool fixing frame one side pole are installed on the same axostylus axostyle.
Described universal swing arm is one, is located at a side of movable knife rack, and this side is corresponding consistent with grain header driving mechanism installed surface.
Depth of beam is higher than the height of crawler belt on the chassis of described grain header.
Described chassis upper beam installs and fixes the seat place and is made by steel plate.
Described connecting rod is falculate warp architecture.
Be respectively equipped with the lifting screw rod on the pole of described tool fixing frame both sides.
Described holder is installed on the axostylus axostyle by spherical bearing.
The blade of described tool fixing frame and movable knife rack is provided with in the same way.
The beneficial effects of the utility model are: the hinge of said structure is cut device and is removed operation at the stalk of leaving over behind the crops results seed specially, has stronger specific aim.The mode that it cooperates with universal swing arm and universal arm shaft bearing realizes that movable knife rack swings, and hinge is cut on chassis that device is installed in grain header puts the beams in place, and has effectively avoided collision obstacle, blocks mud, has twined phenomenon such as grass, guarantees to use normal, reliable.The utlity model has be skillfully constructed, reasonable in design, compact conformation, simple to operate, easy to maintenance, stubble-cleaning is effective, light labor intensity, environmental protection and economy, efficient quick and characteristics such as safe and reliable.
