続ける。Thus, when the cart (6) is reciprocated on the running rail (5) and the scraper (8) is rotated by the drive of the motor, the powder and granules in the hopper (1) are transferred to each inflow opening (10). ) flows down, is scraped out by each scraper (8) below, and is discharged from each discharge opening (2). Even if the powder or granular material tries to form a bridge at the inflow opening (10), the left and right inclined surfaces (10a) (1
Since the inclination angles α and β of 0b) are different, the friction angles of the powder and granule in contact with the left and right inclined surfaces (10a) and (10b) are different, and thus the stress acting on the powder and granule on the left and right is different. As a result, the stress distribution becomes unbalanced, and as a result, the powder flows downward toward the scraper (8) without forming a bridge, and the powder continues to smoothly flow down toward the scraper (8).

なホッパー（１）からの排出が可能となる。As shown in the third figure, the lower end of the inclined side wall (1a) is formed into a vertical surface (11), and the tip of the scraper (8) is extended to a position close to the vertical surface (11). The scraper (8) makes it possible to scrape out the powder and granules up to a position close to the vertical surface (11), so that no scraping remains;
Coupled with the smooth flow of the powder and granules into the scraper (8) through the inlet opening (10) described above, the powder and granules can be smoothly and efficiently discharged from the hopper (1).
