PROBLEM TO BE SOLVED: To provide an automatic dust collector which can be manufactured strongly at a low cost and can remove even smaller foreign matters compared to a conventional dust collector, in the automatic dust collector disposed in a drawing channel provided with a small hydraulic power generator using a small-sized turbine water wheel or a propeller water wheel or the like.SOLUTION: The automatic dust collector comprises a rotary drum part, a frame part and a drive part, a porous plate is provided circumferentially on a circumferential surface of the rotary drum part, and a raking-up screen is provided at a prescribed part of the porous plate. The frame part is formed into a structure of disposing the rotary drum part and the drive part, to be interposed inside a flow path of a drawing channel, and includes a bottom part fixing screen and a sliding-down rake. The drive part adopts means of separating dust raked up by the raking-up screen from the rotary drum by the sliding-down rake and discharging it by rotating a lower side of the rotary drum part at a low speed in a direction opposite to the flow of the drawing channel. |
