Abstract

PROBLEM TO BE SOLVED: To improve work efficiency by rotating a screw conveyor for feeding wastes under a state of being drawn to the discharge port side and thereby satisfactorily feeding the wastes from the discharge port into the compression chamber. SOLUTION: Wasts are stored from the feeding port 11 to the hopper 9 and fed from the discharge port 13 to the compression chamber 17 in the compression box 19 by driving a feeding motor 39. Then, with the compression cylinder 29 actuated, a compressing member 25 is moved to the left. As a result, the wastes are pushed to the left; the compressing member 25 passes near the left end part of the feeding opening 21, cutting a part of the wastes and finally the wastes inside the compression chamber 17 are compressed and solidified into a cylindrical shape under a hermetically sealed state. After the waste are compressed and solidified, the cover member 23 is moved upward by the operation of an opening/closing cylinder, so that the left end of the compression chamber 17 is opened and that the compressed and solidified wastes are discharged from the compression chamber 17.
