As is known from Japanese Utility Model Publication No. 53-49169, etc., there is a discharge vane for discharging powder and granules in the tank toward the outer periphery, and a discharge vane below the discharge vane for discharging the powder toward the outer circumference. It is equipped with a guide vane for raking the granular material to the center, and a discharge vane below the guide vane for discharging the granular material scraped up by the guide vane from the discharge port.

ラを生ずる欠点がある。 As mentioned above, conventional table feeders have a complex structure with multiple sets of rotating blades, and as the inner diameter of the tank increases, the diameter of the rotating blades also increases, and the resistance force due to the powder and granules acting on the rotating blades increases. ,
Requires large driving force. Further, it is not easy to adjust the amount of discharge, and since the rotary blade is not provided with an adjustment part, the only option is to change the rotation speed of the drive device that rotates the rotary blade. Moreover, it is difficult to accurately set the discharge amount due to the structure, and there is a drawback that the discharge amount becomes uneven.

The discharge chamber facing the discharge port is provided in the tank so as to be surrounded by a surrounding wall having an inlet on the front side in the rotational direction of the rotating disk, and the lower edge of the surrounding wall is connected to the upper surface of the rotating disk. An adjustment plate is provided close to the inlet and closes the inlet and is attached to the surrounding wall so as to be movable up and down. In the present invention, when the rotating disk rotates, the powder and granules placed on the rotating disk and transferred in the rotational direction flow into the discharge chamber from the inflow port, and the powder and granules collide with the surrounding wall on the rear side in the rotational direction. It is designed so that it is extruded from the outlet. The amount of powder and granular material to be discharged is determined by moving the adjustment plate up and down. When the adjustment plate is moved upward, the inlet is opened wide, and the discharge amount increases. When the adjustment plate is moved downward, the inflow port is closed, and the discharge amount is decreased.

The rotating disk 3 rotates in the direction of arrow Q (FIG. 2).
As the rotating disk 3 rotates, the powder and granules on the rotating disk 3 are rotated and transferred in the same direction while being placed on the rotating disk 3. Since the inlet 12 is opened in the direction of rotation, the powder and granules are transferred in the same direction. The body flows from the inlet 12 to the discharge chamber 9
flows into. The adjustment plate 13 is fixed at a predetermined height position corresponding to the powder and granular material discharged from the discharge port 8, and is fixed at a predetermined height position corresponding to the powder and granular material discharged from the discharge port 8. The particles flow into the discharge chamber 9 in a layered manner. The granular material that has flowed into the discharge chamber 9 hits the scraping wall 10, is pushed out to the discharge port 8, and is discharged from the discharge port 8.
