The rolling sieve 213 will also rotate with the rotating shaft one 219. At this time, the convex strip 218 will rotate with the rolling sieve 213 and contact with the rotating rod 214. The rotating rod 214 will rotate and drive the supporting rod 216 to move under the action of force. The supporting rod 216 will be limited to upward flipping movement by the limiting support 217.

The wind generated by the rotation of the fan blade 316 will blow the defective grains and impurities screened, so that the impurities remaining in the grains are classified. When the grains fall on the filter screen 314, a certain force will be generated. The filter screen 314 will compress the spring two 318 under the action of force. At the same time, the spring two 318 will generate a certain rebound force to drive the filter screen 314 to reset and achieve the effect of vibration under the limiting action of the supporting plate 317. This avoids the blockage of impurities or grains to the filter screen 314, which affects the discharge of grains. The classified impurities are discharged from the right side of the discharge port two 313 through the blowing of the fan blade 316. The classification through the blowing of the fan blade 316 greatly improves the cleanliness of the defective grains and greatly improves the reutilization effect of the defective grains, avoiding the reclassification of the defective grains by the staff, and greatly reducing the labor of the staff.
