[0025] Example 3: Figure 3 , including a lower warehouse body 100, the lower warehouse body 100 is set to be conical, the upper warehouse body 200 is fixedly installed on the top of the lower warehouse body 100, the top plate 220 is fixedly installed on the top of the upper warehouse body 200, the inner wall of the top plate 220 is rotatably connected to the driving shaft 300 through a bearing, the first grading wheel 310 is fixedly installed on the outer wall of the bottom of the driving shaft 300, the servo motor 320 is fixedly installed on the outer wall of the top of the top plate 220, the signal of the servo motor 320 is connected to the frequency converter 330, and the output shaft of the servo motor 320 and the driving shaft 300 are connected by a belt 321 and a pulley 322.

[0026] The specific usage scenario of this embodiment is: by setting the air inlet pipe 120 to allow high-pressure airflow into the lower bin body 100, by setting the support legs 110 to support the bottom of the lower bin body 100, by setting the discharge roller 141 to control the on and off of the discharge pipe 130, by setting the motor 150 to control the rotation of the discharge roller 141, thereby controlling the discharge roller 141 to release large particles.

[0027] The working principle of the utility model is as follows: when in use, a person skilled in the art turns on the frequency converter 330 to control the servo motor 320 to adjust the speed, then connects the air inlet pipe 120 to an air pump (not marked in the figure), and uses the air pump to deliver high-pressure airflow to the inside of the air inlet pipe 120, then introduces the particles to be classified into the upper bin 200 through the lower bin 221, and drives the first classifying wheel 310 to rotate through the servo motor 320. As the particle material falls into the first classifying wheel 310, under the action of centrifugal force, the particles on the top of the first classifying wheel 310 are thrown to the second classifying wheel 340. Under the action of the high-pressure airflow at the air inlet pipe 120, the small particle material generates an upward lift under the combined action of the centrifugal force of the rotation of the first classifying wheel 310 and the airflow, and then the small particle material is passed through the air outlet pipe 210. After being transported to the outside of the upper silo 200, the larger particles of material fall into the vertebral body inside the lower silo 100 under the action of gravity, and are then discharged into the baffle at the top of the discharge roller 141 through the discharge pipe 130 at the bottom of the lower silo 100. By turning on the motor 150, the motor 150 drives the discharge roller 141 to rotate. Under the rotation of the discharge roller 141, the large particles on the top of the discharge roller 141 fall into the storage bin (not marked in the figure) at the bottom of the discharge pipe 130. After the storage bin is full of granular material, the storage bin needs to be replaced. By interrupting the operation of the motor 150, the storage bin at the bottom of the discharge pipe 130 is removed and replaced. The particle shaping and grading device can continue to work. After replacing the storage bin, the discharge pipe 130 is continued to be discharged by turning on the motor 150.
