Claims (1)

[Scope of utility model registration request] A bottomless annular cavity is formed by installing a rotary disk forming the bottom surface of the storage chamber in the lower part of the storage chamber for accommodating the powder and granular material, and connecting an inner ring and an outer ring with a plurality of lower connecting members around the outer periphery of the rotary disk. A fixed bottom surface is provided below the annular cavity, first and second hollow sub-chambers are arranged in an annular manner on the outer periphery of the storage wall above the annular cavity, and the first hollow The subchamber and the lower part of the storage chamber communicate with each other through a slit-shaped communication opening in the storage chamber wall that opens along the circumference, and an annular cavity is provided at the boundary between the second hollow subchamber and the first hollow subchamber. A bulkhead board is installed that goes down to the top level,
One of the lower ends of the partition plate is a scraped end, and a scraper is provided at the lower middle of the second hollow auxiliary chamber to deflect the inclined powder downward so as to be inserted into the annular cavity. A continuous powder supply device with a discharge port opening at the bottom.
