2. working principle

the corn is fed from the feed inlet, the corn is impacted in the rotor and drum rotating at high speed, the grains are separated by the screen hole, the corn cob is discharged from the tail of the machine, and the corn silk and the skin are discharged from the tuyere. the feed inlet is located at the upper part of the upper cover of the machine. the corn cob enters the threshing chamber through the feed inlet. in the threshing chamber, the corn kernels fall off due to the impact of the rotor rotating at high speed, and are separated through the screen holes.

3. matters needing attention

before working on the thresher, it is necessary to educate the participants on the safe operation, carefully check whether the rotating parts are flexible, and whether the adjustment mechanism is normal. the gearing ratio is required to avoid excessive thresher speed and severe vibration, which may cause personal injury.
