[0026] The first auger 100 includes a first spiral blade shaft 130 , a first cylinder 160 , an inlet anti-leakage baffle 120 and a plurality of ear picking rakes 110 .
[0027] The first spiral blade shaft 130 is coaxially arranged in the first cylinder 160, and a long corn cob inlet hole is opened on the circumferential surface of the first cylinder 160.
