At the top of one end of the screening mesh 13, a first discharge pipe 5 is inclined and fixedly arranged. A blocking mechanism 4 is movably arranged inside the screening cylinder 1 corresponding to one side of the first discharge pipe 5. Through the inclined screening mesh 13, larger granular raw materials can be concentrated towards the position of the first discharge pipe 5, which is convenient for discharging the larger granular raw materials through the first discharge pipe 5, thereby improving the practicability of the device.
[0021] In this embodiment, the stirring paddle 11 is rotatably installed inside the top end of the screening cylinder 1, the servo motor 10 is fixedly installed at the center position of the top end of the screening cylinder 1, and the stirring paddle 11 is fixedly installed at the bottom end of the output shaft of the servo motor 10.

[0022] In this embodiment, the blocking mechanism 4 includes a baffle plate 12, the baffle plate 12 is movably arranged at one end of the first discharge pipe 5 and is in close contact. The shape of the baffle plate 12 is arc-shaped. A chute is opened on the outer wall of the screening cylinder 1 corresponding to the position of the baffle plate 12. A shifting rod 16 is fixedly arranged on the outer wall of the baffle plate 12, and the shifting rod 16 is limited and slidably installed inside the chute. A magnet is fixedly arranged at the top end of the chute, the shifting rod 16 is an iron rod, and the baffle plate 12 blocks inside the chute. The baffle plate 12 can block at one end of the first discharge pipe 5, which can prevent smaller granular raw materials from entering the inside of the first discharge pipe 5, facilitating the full screening of the granular raw materials. Through the magnetic attraction between the magnet and the shifting rod 16, it is convenient to fix the baffle plate 12 above the first discharge pipe 5, facilitating the discharge of larger granular raw materials into the inside of the first discharge pipe 5.
[0023] In this embodiment, a sloping plate is fixedly arranged inside a screening cylinder 1 in an inclined manner at the bottom of the screening mesh 13. One end of the sloping plate is fixedly provided with a second discharge pipe 6. The second discharge pipe 6 is arranged below the first discharge pipe 5. A blower 9 is fixedly installed inside the bottom end of the screening cylinder 1. An air inlet 8 is opened on one side of the bottom end of the screening cylinder 1.

Granular raw materials are added into the interior of the screening cylinder 1 through the feed inlet 2. The servo motor 10 is started. The servo motor 10 drives the stirring paddle 11 to stir the granular raw materials inside the screening cylinder 1. The smaller granular raw materials are discharged downward through the screening mesh 13, and the larger granular raw materials remain on the top of the screening mesh 13. At the same time, the stirring paddle 11 drives the movable rod 14 and the brush to rotate on the top of the screening mesh 13 through the torsion spring rotating shaft, and the brush is always in contact with the top of the screening mesh 13 to facilitate the cleaning of the granular raw materials on the top of the screening mesh 13 and prevent the screening mesh 13 from being blocked by the granular raw materials. The larger granular raw materials are concentrated towards the position of the baffle 12 and the first discharge pipe 5. The smaller granular raw materials fall on the sloping plate and roll along the sloping plate into the interior of the second discharge pipe 6. The electromagnetic valve on the air outlet pipe 15 is opened, and the electromagnetic valve on the bent pipe 7 is closed. The blower 9 is started. The blower 9 draws air through the air inlet 8 and enters the interior of the second discharge pipe 6 through the air outlet pipe 15 to facilitate the transportation of the smaller granular raw materials. After screening is completed, the electromagnetic valve on the air outlet pipe 15 is closed, and the electromagnetic valve on the bent pipe 7 is opened. The lever 16 is toggled upward. The lever 16 drives the baffle 12 to move upward. The larger granular raw materials enter the interior of the first discharge pipe 5.
