Claims

[Claims for Utility Model Registration] A circular rotating body is rotatably provided on the lower side of a powder raw material dropping device about a horizontal axis, and a plurality of fitting recesses are formed along the outer circumferential surface of the rotating body. Then, a measuring block having a storage recess for storing the powder raw material or a blind lid block having no storage recess is fitted, and the powder raw material falling onto the rotating body is placed in the storage part of the measuring block. At the same time as the rotating body rotates, the raw material is caused to fall onto a conveyor placed below, and the amount of raw material supplied to the conveyor is controlled by the ratio of the measuring block and the blind lid block. In the powder raw material metering and feeding device, the fitting recess is opened at a side end surface of the rotating body, and the measuring and blind lid block is inserted laterally through the opening and fitted. , and a fixed plate having an engaging portion that abuts and engages with the side end faces of the blocks is provided on the side end face of the rotating body so as to be rotatable at a predetermined angle, and the fixed plate prevents the blocks from coming off. A metering and feeding device for powder raw materials, which is characterized by:
