PROBLEM TO BE SOLVED: To solve the problems of the grains from which the branches are separated, easily dropping and causing the deficiency in a lifting and conveying force of a group of threshing teeth in a conventional conveying means for secondary reduction by an auger, designed so that the grains with the branches mixed with the secondary product may be subjected to the threshing treatment by forming a part of a conveying passage of the auger into a threshing tooth group for providing the threshing action while conveying the secondary product in the conventional conveying means for the secondary reduction by the auger. SOLUTION: This secondarily reducing device for goodly lifting and conveying grains in the conveying device for secondary reduction by the auger has a threshing tooth group for providing the threshing action to the second product sprouted by a sprouting blade at the terminal end part of a secondary conveyor while conveying the secondary product, installed at a part of the conveying passage of the auger, and leads installed in the inner wall face of a cylindrical case, corresponding to the threshing tooth group to assist the lifting and conveying capacity, so that the reducing device can prevent the drop of the grains while carrying out the threshing treatment of the grains with the branch, and well lift and convey the grains.
