To uniformly distribute the grain, and to eliminate the noise by providing a plurality of grain feeding ports on a bottom part of an upper transfer gutter to feed the grain to a storage chamber, and successively opening/closing the grain feeding port other than those on the transfer end part side with an opening/closing plate.
Grain feeding ports 29, 30 to drop and feed the grain to be transferred by an upwardly transferring screw 6 into a storage chamber 9 are provided in the vicinity of a starting end part in the transfer direction and in the center of a bottom plate 28 to form a bottom part 27 of an upwardly transferring gutter 7. The bottom plate 28 is extended from an inner side surface of a rear machine wall 4 of the storage chamber 9 to an inner side of the prescribed distance therefrom, and a grain feeding port 31 is provided on a final end part side in the transferring direction of the upwardly transferring gutter 7. A longitudinally movable opening/closing plate 32 which is moved to individually open or jointly close the grain feeding ports 29, 30 is provided on the lower side of the bottom plate 28. The opening/closing plate 32 controls the movement in the longitudinal direction through the forward/rearward revolution of an opening/closing motor. The grain is dropped and fed successively with the prescribed temporal intervals from the grain feeding ports 29, 30, 31 into the storage chamber 9 while the position of the opening/closing plate 32 is detected by sensors 38, 39, 40. The grain can be uniformly distributed and the noise is prevented thereby.
