PURPOSE:To save power consumption by providing a rotary disk for preventing pressure of a powder and grain body in a storage body from being applied to send-in and send- out vanes, in a device for discharging powder and grain body such as a mixed feed, etc., to make the rotation torque of vanes small. CONSTITUTION:When a rotary shaft 9 is rotated causing a send-in vane A and a send-out vane B to rotate, a powder and grain body in a storage body 1 flows into a discharging body 2 through a central flow-in port 12 and a peripheral flow-in port 13 in a condition that the pressure of the powder and grain body in the storage body 1 is prevented from being directly applied to the vanes A, B by means of a rotary disk 4 at a connecting part between the storage body 1 and the discharging body 2. The powder and grain body which flowed in through the flow-in port 13, falls on the outer peripheral part of a fixed disk 3, is sent into the centerl part of the discharging body 2 by the action of the vane A, falls on the top of a bottom plate 2b of the discharging body through a falling port 14, and is discharged through a discharge port 11. On the other hand, the powder and grain body which flowed in through the flow-in port 12 falls on the bottom plate 2b of the discharging body and is discharged through the discharge port 11. Since the pressure of the powder and grain body in the storage body 1 is intercepted by the disk 4, the torque of the vanes A, B can be reduced. |
