[0028] In a preferred embodiment, when the swing plate 311 moves to the right, the second connecting rod 507 drives the second piston 506 to move synchronously, thereby injecting the air in the second cylinder 505 into the first cylinder 501, and driving the first piston 502 to drive the first connecting rod 503 to move left, thereby impacting the drive plate 304 through the impact ring 504, achieving vibration removal of the spiral leaf 305, and preventing the rare earth raw material from sticking to the surface of the spiral leaf 305. The torque sensor 508 can monitor the output torque of the motor 301 in real time and set a corresponding threshold. When the output torque is greater than the corresponding threshold, it indicates that a large amount of rare earth raw material is stuck to the surface of the spiral leaf 305. At this time, the electric telescopic rod 516 is controlled to move, driving the second clamping plate 515 to move, clamping the support arm 314 between the first clamping plate 514 and the second clamping plate 515. Then, the spiral leaf 305 can swing left and right while rotating, and cooperate with the impact ring 504 to improve the vibration removal effect of the spiral leaf 305 and ensure the feeding efficiency.

[0029] Specifically, the working principle of this rare earth raw material feeding device is as follows: when in use, the rare earth raw material is poured into the upper hopper 2 through the conveyor belt, and the spiral blade 305 is driven to rotate by the motor 301 to transport and feed the rare earth raw material, and when the motor 301 drives the sleeve shaft 302 to rotate, the driving wheel 316 and the second protrusion 317 are driven to rotate synchronously. When the second protrusion 317 contacts the surface of the first protrusion 315, the swing plate 311 is driven to move to the right, and the driving shaft 310 can be driven by the driving groove 313 to drive the knocking rod 307 to rotate, and the knocking block 308 is used to knock the reinforcing plate 309, and the rare earth raw material sticking to the inner wall of the feed box 1 is vibrated to avoid blockage. When the first spring 319 is compressed and the second protrusion 317 is separated from the first protrusion 315, under the action of the first spring 319, the swing plate 311 is driven to move left, realizing the reciprocating swing of the swing plate 311, continuously vibrating the feed box 1, and ensuring the normal feeding work.

[0030] When the swing plate 311 moves back and forth left and right, it drives the vertical plate 404 and the driving block 405 to move synchronously, and squeezes the wedge surface of the impact block 401, so that the impact blocks 401 on both sides move away from each other and impact the inner wall of the feed box 1, which can vibrate the rare earth raw materials sticking to the inside of the feed box 1, ensure the normal discharge of the raw materials, and improve the feeding efficiency.

[0031] When the swing plate 311 moves to the right, the second connecting rod 507 drives the second piston 506 to move synchronously, thereby injecting the air in the second cylinder 505 into the first cylinder 501, and driving the first piston 502 to drive the first connecting rod 503 to move left, thereby impacting the drive plate 304 through the impact ring 504, achieving vibration removal of the spiral blade 305 and preventing the rare earth raw material from adhering to the surface of the spiral blade 305. The torque sensor 508 can monitor the output torque of the motor 301 in real time and set a corresponding threshold. When the output torque exceeds the corresponding threshold, it indicates that a large amount of rare earth raw material is adhered to the surface of the spiral blade 305. At this time, the electric telescopic rod 516 is controlled to move, driving the second clamping plate 515 to move, clamping the support arm 314 between the first clamping plate 514 and the second clamping plate 515. Then, the spiral blade 305 can swing left and right while rotating, and cooperate with the impact ring 504 to improve the vibration removal effect of the spiral blade 305 and ensure material feeding efficiency.
