PROBLEM TO BE SOLVED: To surely recover grain (free grain over rack) misplaced in massive discharged culms and to control a threshing loss in a threshing apparatus for removing grains attached to the ear tip part of reaped grain straw. SOLUTION: Stationary plates 40c and 40b for coupling a revolving shaft, which are attached to the inside of a body 40, are equipped with a blowing blade piece 48 as a blowing means. An air flow F is formed in the body 40 by integrally rotating the blowing blade piece 48 and the revolving shaft 41. A plurality of release holes 49 for blowing out the air flow F are formed between adjacent screw blades 22 on the outer peripheral surface of the body 40. COPYRIGHT: (C)2009,JPO&INPIT
