Description
Technical field
The present invention relates to rice wheat combine harvester tool manufacturing technology field, more particularly to a kind of rice-wheat threshing device notch board
Sieve.
Background technology
Sheller unit is one of thresing machine and the most important workpiece of grain harvesting machine, and concave grate be sheller unit most
One of important workpiece；The Main Function of concave grate is to allow the grain for taking off to separate with straw through sieve aperture,
Simultaneously the straw detention after threshing on compass screen surface, to evict from outside body；The quality of concave grate performance directly affects abjection seed
The percentage of impurity of grain.
The concave grate of generally rice-wheat threshing device is grid-type concave sieve, sieve aperture band steel and steel wire that grid-type concave is sieved
Composition, generally overall structure, when the turgor of the corn or seed that harvest different cultivars is different, cereal kernel it is big
Little difference is very big, needs the size that sieve aperture is adjusted according to actual results situation, traditional concave grate to be difficult to accomplish adjustable knotter screen
The size in hole.
Existing concave grate is easily blocked in threshing, and concave grate is more particularly when maslin moisture content is higher
Easily blocking, because the cleaning for being limited concave grate by space is extremely difficult, and needs sheller unit to take apart to be cleared up, increasing
Manual labor, efficiency has been added to reduce.
Now the more commonly used grid-type concave sieve is generally overall structure, is mostly welded, maintenance difficult and maintenance
It is relatively costly.
The content of the invention
The present invention is to overcome the deficiencies in the prior art, there is provided a kind of rice-wheat threshing device concave grate.This kind of sheller unit
Concave grate can adjust the size of sieve aperture according to actual results situation；When the higher corn of results moisture content, this kind of threshing
Device concave grate prevents the effect for blocking preferably, in time straw can be cleaned out into sheller unit；Meanwhile, this kind of sheller unit is recessed
Screen mostly is thread connection connection, key connecting and pin connection, is easy to keep in repair when damage of components and changes.
The technical solution used in the present invention is：A kind of rice-wheat threshing device concave grate, including it is horizontal band steel, side arc band steel, fixed
Axle, rotating shaft, grate size, coupling block, shaft gear, drive gear, drive shaft；Characterized in that, the horizontal band steel and the side arc
Band steel is connected by thread connection, constitutes the framework profile of concave grate；There is a screw thread shaft end of the dead axle, the dead axle with it is described
Side arc band steel is connected by thread connection；One end of the rotating shaft is connected by bearing connection with shelling storehouse, and the other end passes through pin
It is connected with the coupling block；Dead axle and the interlaced arrangement of rotating shaft；The grate size is connected by thread connection with dead axle and rotating shaft；
The coupling block is connected with the shaft gear by key connecting；The drive gear passes through key connecting phase with the drive shaft
Even；The drive shaft is connected by belt wheel with power set.
Further, the grate size is all uniform arrangement and at a distance of 100mm but adjacent fixed on the dead axle and the rotating shaft
Two nearest grate sizes of axle and rotating shaft axial distance are apart 50mm；Grate size on the dead axle is fixed, and described
Grate size in rotating shaft can be as rotating shaft rotates；When the place datum level of the rotating shaft grate size is vertical with compass screen surface, notch board
The sieve aperture of sieve is in maximum rating；When the place datum level of the rotating shaft grate size is tangent with compass screen surface, the sieve aperture of concave grate is in
Minimum state；When the place datum level of the rotating shaft grate size is angled with compass screen surface, the slot size of concave grate is in most
Greatly between state and minimum state, can be changed according to actual results situation.
Further, when the moisture content of maslin is higher, the rotating shaft can be made in the driving lower edge of power set
Turn to rotate in the opposite direction with threshing cylinder, depending on rotating speed is according to practical situation, the rotation of the grate size can make threshing roll
Grain straw between cylinder and concave grate is discharged in time, prevents the generation of stopping state.
Further, traditional concave grate is that band steel and steel wire are constituted, and the integrative-structure being mostly welded, the rice wheat takes off
Grain device concave grate mostly is thread connection connection, key connecting and pin connection, is easy to keep in repair when damage of components and changes.
The invention has the beneficial effects as follows：Simple structure, it is easy to manufacture, cost is relatively low；Can be according to actual results feelings
Condition adjusts the size of sieve aperture, so as to be suitable for the seed of the different corn of kind or different turgors；Adapt to moisture content
The results condition of higher corn, in time can discharge grain straw from sheller unit, effectively prevent the generation of stopping state, energy
Manual labor is effectively reduced, efficiency of crop is improved；The characteristics of being easily changed impaired parts and be easy to maintenance is to a certain extent
Improve the service life of concave grate.
