The screw conveyor device 1 includes a trough 2 attached to a lower portion of a hopper H that stores dust and the like, and a feed screw 3 that is stored in the trough. The trough 2 is connected to the hopper H by opening the entire upper surface thereof, the discharge port 4 is formed on one side thereof, and the feed screw blade 6 is provided on the shaft 5 of the screw 3. However, the screw blade 6 is formed only up to the discharge port 4, and the blade is omitted while passing through the discharge port 4. On the opposite side, a reverse feed blade 7 having a reverse feed angle is formed. To form. Reference numeral 8 indicates a drive sprocket wheel.

向の回転により強制的に排出される。In the above structure, when the dust in the hopper H is discharged, the feed screw 3 is driven. As a result, the dust in the hopper H is pushed toward the discharge port 4 side by the rotation of the screw 3, and the dust is also dropped and supplied to the discharge port 4 directly from above. In this case, since the discharge port 4 is provided with the scraping blade 10, the dust in the discharge port is agitated without being accumulated and is forcedly discharged by the downward rotation of the scraping blade.
