Description
Technical field
The present invention relates to a kind of united reaper, especially a kind of all-round installed threshing separator of united reaper belongs to agriculture
Industry harvest machinery technical field.
Background technology
For a long time, the threshing angle of united reaper is always between 200 ° to 270 ° because threshing cylinder upper end with
There was only cereal centrifugation between cover plate, in the absence of threshing operations, therefore the threshing detached job of traditional harvest machine is less efficient.
Develop with the maximization of united reaper, the feed quantity of harvester is increasing, be badly in need of improving harvester threshing point as far as possible
From operating efficiency.
The content of the invention
It is an object of the invention to：Propose it is a kind of can with the all-round installed threshing separator of the united reaper of 360 ° of threshings, from
And the threshing detached job efficiency of harvester is given full play to, the need for meeting united reaper maximization development.
In order to achieve the above object, the basic technical scheme of the all-round installed threshing separator of united reaper of the present invention is：Bag
Include the threshing cylinder in concave grate and recessed screen in the pairing, the upper concave grate by the circular arc sieve plate with latticed porosity rima with
And it is fixed on the spiral guide plate composition in sieve plate, arc plate that the recessed screen is distributed by axially spaced-apart, it is distributed in
Circular arc grating between adjacent circular arc plate and with arc plate and the axially extending horizontal stroke of the connected circumferentially-spaced distribution of circular arc grating
Plate is constituted, and the two ends of the recessed screen have inlet and outlet respectively；The threshing cylinder contains rotation driving axle, the drive
Moving axis is fixedly connected by disk with being distributed in one group of central siphon of disk excircle, and the central siphon is distributed by axially spaced-apart
Spike-tooth and the outside rasp bar with line muscle be connected, the line muscle is distributed in rasp bar outer surface with the hand of spiral.
During harvesting, grain inlet enters threshing in threshing cylinder, the cereal kernel taken off respectively by upper concave grate and
Concave plate screening is separated out, and stalk and is not purified seed under the guiding of guide plate, is moved to outlet, is handled into follow-up system.
Due to upper and lower concave grate of the present invention using butted structure, upper and lower concave grate constitutes all-round 360 ° with threshing cylinder to be taken off
The system of grain separation, therefore during threshing detached job, threshing cylinder is able to 360 ° of all-round threshings, effectively increases harvesting
De- point of ability of machine；And the guide plate in upper concave grate has threshing concurrently and cereal is oriented to the effect of separation, makes the smooth stream of cereal
Move to outlet, effectively reduce operation consumption, further increase the threshing detached job efficiency of harvester.
Further improve of the invention is that the rasp bar is made up of tangential face and Nei Yan faces, and the line muscle is located at tangential face
On.Line muscle, which is located on tangential face, can effectively improve threshing efficiency and threshing performance.
The present invention is further improved, and the tangential face of the rasp bar is with interior face of prolonging into 100 ° of -120 ° of angles.In threshing
During, when grain straw is by rasp bar surface, certain guide effect can be played, by rasp bar surface after threshing operations
Grain straw along threshing cylinder import to export direction export.
The present invention is further improved, and the line muscle with the spiral guide plate identical hand of spiral to be distributed in
Rasp bar outer surface.Stalk guide functions can be so further functioned as, the operating efficiency of whole sheller unit is improved, is effectively increased
The feed quantity of harvester.
The present invention also further improve is that the outlet is made up of the outlet side plate of grating floor He its both sides；It is described
Import is made up of the import side plate of hollow out bottom plate He its both sides.It is spacing to importing and exporting stalk by both sides import side plate, improve straw
Stalk passes in and out threshing efficiency；Hollow out bottom plate is conducive to take off and being mixed in the grain screening in stalk and go out.
The present invention further perfect be, the outside of the hollow out bottom plate is in sieve-mesh in grid-like, inner side.The structure
Design consider the cereal taken off often in the outer part in " volt of lying ", in the inner part in " erecting " shape, and grid is easy to " volt of lying "
Cereal leaks down to sift out, and the cereal that sieve aperture is then easy to " erecting " leaks down to sift out.
