[0024] During specific use, the conveying chain 2 transports the corn cobs harvested by the corn harvester and some debris (such as weeds and straw) that have not been removed in time. The corn cobs fall from the discharge port 3 onto the corn husking roller 24 due to their heavy weight. The impurities in the corn cobs are blown by the impurity blowing fan 4, and the impurities are separated from the corn and enter the micro-impurity cylinder 25 from the micro-impurity suction port 26, and then discharged from the micro-impurity discharge port 27 at one end of the micro-impurity cylinder 25.

The debris in the debris discharge drum 9 is crushed by the crushing teeth 12, and the negative pressure generated by the rotation of the suction fan 13 draws the crushed debris to the debris discharge port 20 for discharge. At the same time, the negative pressure generated by the rotation of the suction fan 13 draws the fine and light debris on the corn husk roller 24 to the debris discharge port 20 for discharge through the micro-impurity suction port 26.
