The operation principle of the present invention：Start motor, motor driving live roller, live roller drives filter screen type sieve roller
Rotate, grain to be screened is poured into along feed hopper, grain rotates under the action of the centrifugal force, by filtering meshes, prevents because of rolling
Cylinder centrifugal force is excessive and reduces the orderly screening that the part of screening efficiency ensures grain, shrivelled kernel, wheat bran, the wheat head being mixed into grain
Small miscellaneous outlet must be entered with light impurities such as dust silts, grain fine work enters grain-export, and the impurity entrance of bulky grain is big miscellaneous
Export, the air exhauster at grain-export, the light impurities being mixed into grain can be removed.
The beneficial effects of the invention are as follows：1st, drum-type grain screening machine of the invention, in conventional motors, roller, casing, rolling
On the architecture basics of cylinder, the improvement of structure is carried out to roller, and roller is placed in parallel, while added in roller anti-
Only centrifugal force is excessive and reduce the part of screening efficiency so that the grain positioned at upper strata can be contacted fully with screen cloth, stable to have
The screening of sequence, improves screening efficiency.
2nd, prevent that centrifugal force is excessive and reduces the part of screening efficiency, have selected filtering meshes inner surface arc or open up
The design of the circular slab of through hole so that in the case of higher rotation speed, larger centrifugal force, grain unordered will not be thrown away roller, but
Under the barrier of arc and circular slab, thrown away outside arc and in the through hole of circular slab so that small miscellaneous, grain, big miscellaneous
Screening is more accurate.
3rd, the aspiration channel and air exhauster designed at grain-export, the grain for entering grain-export can further be cleaned,
The dust impurity on grain surface is absorbed, improves the quality of grain after screening.
