PURPOSE: To smoothly tear refuse bags by the transporting force of a conveyor during transporting with this conveyor. CONSTITUTION: Blades 13 are mounted at lifter pieces 12 of the conveyor 10 from a pit P to a classifying stage. The conveyor is provided with vertically movable rollers 20, 30 in its sloped part beginning to ascend. The refuse bags (a) from the pit P come into contact with the roller 20 at an ascending port and are ruptured by the blades 13 under the resistance force thereof. At this time, downward force is acted on the refuse bags (a) due to the ascending port and there are substantially no bags which advance beyond the roller 20. The refuse layers are leveled off by the ruptured bags. Namely, the refuse bags are supplied at a fixed rate to the classifying stage. The front side roller 20 is provided with disks at required intervals and the rear side roller 30 is formed to a cylindrical shape. Shock absorbers are mounted at the rollers 20, 30. |
