PURPOSE:To prevent the generation of the bridge in a hopper when dust is taken out, by mounting a cylindrical chute made of a flexible material to the lower opening part of the hopper provided to the lower part of a dust collector and binding the chute to close said hopper. CONSTITUTION:A dust collection container 1 has pieces of filter cloth 3 taking dust from air and a back pressure shaking apparatus 5 falling off dust of the filter cloth 3. A cylindrical chute 7 made of a flexible material is mounted to the lower opening of the hopper 6 provided to the lower part of the dust collection container 1 and tied to close the hopper 6. Therefore, at the time of back pressure shaking, the chute 7 moves up and down, and the generation of a bridge and the solidification dust in the hopper 6 are prevented by the up-and-down movement of the chute 7 and dust can be smoothly taken out. When a definite amount of dust is accumulated in the hopper 6, a clamp part 12 is united and the dust in the hopper 6 can be taken out through the chute 7.
