Claims

[Scope of Claim for Utility Model Registration] (1) An inverted conical hopper with a perforated discharge plate at the bottom discharge port, and a rotatable scraper provided at the bottom of the hopper near the top surface of the perforated discharge plate. and a driving arm coupled to the scraper and rotating the scraper along the upper surface of the perforated discharge plate;
A powder supply device comprising a drive means for driving the drive arm. (2) The scraper includes a first scraper that rotates in a central region of the upper surface of the perforated discharge plate, and a peripheral region that surrounds the rotation region of the first scraper that is on the upper surface of the perforated discharge plate. The powder supply device according to claim 1, further comprising a second scraper. (3) a screw feeder installed in the center of the hopper outlet to discharge the powder and granules in the hopper;
A perforated discharge plate provided at the outer annular discharge port of the screw feeder, a scraper provided near the upper surface of the perforated discharge plate, and a rotation drive for rotating the scraper along the upper surface of the perforated discharge plate. A powder supply device comprising means. (4) Claim (3) characterized in that the screw feeder and the swing drive means are driven by the same rotational drive source that can rotate in opposite directions.
The powder supply device described above.
