FEEDING AGITATOR

PROBLEM TO BE SOLVED: To reduce the foreign sound and vibration, which are developed by raw materials entangled by the clearance between an agitator and the inner wall of a feeding hopper and, at the same time, improve the agitating effect of the agitator by a method wherein a plurality of projecting parts extending near the inner wall of the hopper are provided in the blades of an agitator. SOLUTION: In the wall part of a feeding hopper 1, a rotary shaft 6, which is rotatingly driven with a motor, is horizontally protrusively provided. To the tip part of the rotary shaft 6, a forwardly directed channel-like agitator 7 is fixed. On both the blades 7a of the agitator 7, columnar projecting parts 8 extending near the inner wall of a feeding hopper 1 are provided alternately. Further, stock laminarly sticking to the clearance position 9 between the blades 7a of the agitator 7 and the inner wall of the feeding hopper 1 can be scrapped off with the projecting parts 8. Furthermore, by making the dimension (a) between the blades 7a of the agitator 7, the agitator 7 rotates smoothly even when granular matters are entangled by the clearance portion 9.
