[0021] Preferably, an end ear 401 is provided at the top of the rotating drum 4, and the end ear 401 is rotatably connected to the top of the container 1. The top of the end ear 401 is slidably connected to multiple corner pressure blocks 5, and the bottom end of the corner pressure block 5 is fixedly connected to the top surface of the container 1. The end ear 401 and the corner pressure block 5 can limit the rotating drum 4 to prevent it from falling off.

[0022] Preferably, a ring gear 6 is fixedly sleeved on the upper part of the rotating drum 4, and a gear 7 is connected to one side of the ring gear 6. The gear 7 is fixedly connected to the output end of the motor 8. The upper part of the motor 8 passes through and is fixedly connected to the top of the container 1. The rotating drum 4 can be driven to rotate by controlling the rotation of the motor 8.

[0023] Preferably, a limiting block 1001 is fixedly connected to the inner side of the rear end of the support rod 10 to limit the horizontal position of the bulk plate 11.

[0024] Preferably, the front end of the bulk plate 11 is in the shape of a right-angled triangle, and a side baffle 12 is fixedly connected to the side of the bulk plate 11. The side baffle 12 is evenly provided with a plurality of through holes 1201. In a rotating state, the front ends of the four bulk plates 11 can be spliced ​​to prevent alumina powder from being discharged from the center. The alumina powder can be dispersed through the bulk plates 11 and the through holes 1201 to ensure the uniformity of the discharge.

[0025] Preferably, the vertical length of the second fixed block 16 is greater than the vertical length of the first fixed block 14 to ensure that in a non-rotating state, the counterweight block 17 can slide to the end of the second fixed block 16, thereby causing the front end of the bulk plate 11 to fall and complete the unloading process from the center position.

[0026] Working principle: First, the alumina material is passed into the container 1 through the discharge port 2, and the alumina material passes through the rotating drum 4 in turn and falls into the triangular front end of the bulk plate 11. Under the action of gravity, the bulk plate 11 rotates inwardly and downwardly with the rotating rod 13, so that a discharge channel appears in the center, and then the alumina material falls directly into the center position of the container 1. Then the motor 8 is controlled to rotate, thereby driving the gear 7 and the ring gear 6 to rotate, and then driving the rotating drum 4 and the bulk plate 11 to rotate. Under the action of centrifugal force, the counterweight block 17 slides outward along the sliding rod 15 to the end near the first fixed block 14, and the centrifugal force at the outer edge of the bulk plate 11 is increased. The bulk plate 11 rotates with the rotating rod 13 toward a horizontal position. At this time, the alumina material slides along the outer edge of the bulk plate 11 in the horizontal direction under the action of the rotating centrifugal force. At the same time, some alumina powder will be scattered from the through hole 1201 to improve the uniformity of the bulk material. Then the motor 8 is turned off and the bulk plate 11 stops rotating. In the absence of centrifugal force, the counterweight block 17 moves along the slide rod 15 toward the end of the second fixed block 16 under the action of gravity, causing the weight of the front and rear ends of the bulk plate 11 to be unbalanced. Then the bulk plate 11 rotates toward the inner and lower part again with the rotating rod 13. Finally, the above process is repeated to complete the intermittent uniform unloading process of alumina.
