Abstract

The utility model discloses a corn sheller. In order to resolve the problem that a separating grid and a sheller cylinder can be easily damaged due to high impact force, the front of the separating grid is hinged with a chassis of the corn sheller; vertically downward screws are respectively welded on both ends of the tail of the separating grid; the lower ends of the screws pass through side lugs fixed on the chassis and are locked by nuts; and springs are assembled on the screws between the side lugs and the separating grid. The utility model utilizes the spring damper mechanism to reduce the impact force generated by the separating grid in order to prevent the separating grid and the sheller cylinder from being damaged, so that the service life of the product can be prolonged. The axial lines of shelling rib teeth make a certain included angle with the axial line of the sheller cylinder, so that shelling can become more effective.

The utility model is hinged on the front portion of bolter on the frame, the rear end of bolter can be rotated around front end, and at the rear portion of bolter mounting spring damping, reduce the impulsive force that produces on the bolter by this spring shock absorption mechanism, to avoid damaging bolter and threshing cylinder, to prolong the service life of product.

As preferred embodiment of the present utility model, above-mentioned granule-stripping reinforcement tooth extends axially along described threshing cylinder, and the angle of the axial line of this granule-stripping reinforcement tooth and threshing cylinder axle center line is α, and the size of α is 0～15 degree.Become cone-shaped because corn ear is whole, therefore, with the granule-stripping reinforcement tooth axial line and the threshing cylinder axle center is linear forms an angle better threshing.

As improvement of the present utility model, threshing bin is stretched out at the central shaft two ends of above-mentioned threshing cylinder, and by the bearing supporting that is contained in the bearing block, described bearing block is installed on the frame, and this bearing block is an integral casting forming.By with the bearing block integral casting forming, increase its intensity, increase the service life.

With respect to prior art, the beneficial effects of the utility model are:

(1) the utility model reduces the impulsive force that produces on the bolter by this spring shock absorption mechanism, to avoid damaging bolter and threshing cylinder, to prolong the service life of product;

(2) the utility model helps better threshing with the granule-stripping reinforcement tooth axial line and the threshing cylinder axle center is linear forms an angle;

(3) with the bearing block integral casting forming, increase its intensity, increase the service life.
