PULVERULENT BODY TRANSFERRING DEVICE

摘要

PURPOSE:To form a scraper conveyer and a screw conveyer integrally with each other to reduce cost by providing projectingly a pair of screw blades on a shaft body of the screw conveyer and forming a notch for preventing the conveyer from interference with flights on a portion of said blade. CONSTITUTION:A drive shaft 2 of a screw conveyer 1 is provided with a pair of screw blades 21 having the spiral directions different from each other and projecting from the left and right portions except for the central portion of the shaft. In this case, the screw blade 21 is formed axially with a notch 22 for preventing the screw conveyer 1 from interference with a flight 6. When a sprocket 4 is rotated by the drive of the drive shaft 2, the flight 6 sends dust accumulated on the bottom 8 of a hopper chamber to the lower portion of the drive shaft 2 through a chain 7. And the screw blade 21 collects the dust in the lower central portion of the drive shaft 2 and discharges the dust from a rotary valve 15 to the outside of this device.
