[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0013] 1. By setting a discharge mechanism, a collection mechanism, and a proportioning mechanism on one side of the screening box, the discharge mechanism is equipped with a rotatable gear plate. When the fourth bevel gear rotates, it drives the fifth bevel gear on the rotating shaft inside the proportioning mechanism to rotate simultaneously. The rotation of the rotating shaft drives the rotating disk and the limiting disk to rotate simultaneously. The rotation of the rotating disk drives the limiting post to rotate. The limiting post rotates and engages with the limiting slot on the rotating plate. The movement of the limiting post drives the rotating plate to rotate. When the rotating plate rotates to a certain angle, the limiting post disengages from the limiting slot, and the rotating plate stops rotating. At the same time, the rotation of the rotating plate drives the connecting shaft and the collection mechanism to rotate simultaneously. The transmission gears on the connecting shaft mesh with each other. The rotation of the transmission gears drives the transmission gear to rotate. When the rotating plate stops rotating, the collection box is located below the conveying pipe. At the same time, the connecting hole on the gear plate is connected to the connecting hole on the fixed plate, so that the material is discharged from the inside of the screening box. When the rotating plate rotates again, the connecting hole on the gear plate and the connecting hole on the fixed plate are misaligned, so that the material will not be discharged and there will be no waste of material. At the same time, the collection box with the material rotates out, making it convenient for the user to replace the collection box.
[0014] 2. By installing a first screening screen, a second screening screen, and a conveyor plate inside the screening box, the first screening screen separates larger materials, and the second screening screen separates smaller materials. Since the first screening screen, the second screening screen, and the conveyor plate are all installed at an angle, it is convenient to transport materials to the discharge port for easy material discharge. The rotation of the stirring shaft will drive the fixed block, and the rotation of the fixed block will drive the brush strip to rotate. The rotation of the brush strip will continuously move the material, speed up the material screening, and improve the working efficiency of the device. Attached Figure Description

[0028] By adopting the above technical solution, the rotation of the rotating shaft 1205 drives the rotating disk 1201 and the limiting disk 1202 to rotate simultaneously. The rotation of the rotating disk 1201 drives the limiting post 1204 to rotate. The limiting post 1204 rotates and engages with the limiting slot 1208 on the rotating plate 1207. The movement of the limiting post 1204 drives the rotating plate 1207 to rotate. When the rotating plate 1207 rotates to a certain angle, the limiting post 1204 disengages from the limiting slot 1208, and the rotating plate 1207 stops rotating. At the same time, the rotation of the rotating plate 1207 drives the connecting shaft 1209 and the collecting mechanism 10 to rotate simultaneously. The transmission gear 1211 on the connecting shaft 1209 and the transmission... The drive gears 1211 mesh with each other, and the rotation of the transmission gear 1211 drives the transmission gear 1211 to rotate. When the rotating plate 1207 stops rotating, the storage box 1003 is located below the conveying pipe 803. At the same time, the connecting hole 807 on the gear plate 802 is connected to the connecting hole 807 on the fixed plate 806, so that the material is discharged from the inside of the screening box 1. When the rotating plate 1207 rotates again, the connecting hole 807 on the gear plate 802 and the connecting hole 807 on the fixed plate 806 are misaligned, so the material will not be discharged and there will be no waste of material. At the same time, the storage box 1003 with the material rotates out, making it convenient for the user to replace the storage box 1003.
[0029] The screening mechanism 14 includes a first screening screen 1401 located above the inside of the screening box 1. A second screening screen 1402 is located below the first screening screen 1401.

A stirring shaft 1405 is located inside the first screening screen 1401 and the second screening screen 1402. The upper end face of the stirring shaft 1405 passes through the screening box 1 and the support block 2 and is fixedly connected to a third bevel gear 304. A pair of fixing blocks 1406 are fixedly connected to the outer wall of the stirring shaft 1405. The upper end face of the fixing ring 1404 is provided with a first fixing groove 1407. The first screening screen 1401 and the second screening screen 1402 are both provided with brush strips 1408. The side wall of the brush strip 1408 is provided with an insertion hole 1409.

The second fixing groove 1413 is provided with a second fixing head 1414, and the second fixing head 1414 is fixedly connected to the brush strip 1408.
[0030] By adopting the above technical solution, the first screening screen 1401 screens out larger materials, and the second screening screen 1402 screens out smaller materials. Since the first screening screen 1401, the second screening screen 1402 and the conveyor plate 1403 are all installed at an incline, it is convenient to transport materials to the discharge port for easy material discharge. The rotation of the stirring shaft 1405 will drive the fixed block 1406, and the rotation of the fixed block 1406 will drive the brush strip 1408 to rotate. The rotation of the brush strip 1408 will continuously move the material, speed up the material screening and improve the working efficiency of the device.
[0031] Working principle: The material for producing plastic buckets is poured into the screening box 1 through the inlet. Inside the screening box 1, from top to bottom, are installed a first screening screen 1401, a second screening screen 1402, and a conveyor plate 1403. The first screening screen 1401 filters out larger materials, and the second screening screen 1402 filters out smaller materials. Since the first screening screen 1401, the second screening screen 1402, and the conveyor plate 1403 are all installed at an angle, it facilitates the conveying of materials to the outlet. The servo motor 4 and the vibration motor 13 are started. The vibration motor 13 drives the screening box 1 to vibrate, preventing materials from getting stuck in the screening screens. The servo motor 4 drives the output end to rotate, which in turn drives the second bevel gear inside the transmission box 301. When wheel 303 rotates, the second bevel gear 303 rotates, driving the first bevel gear 302 to rotate. The first bevel gear 302 rotates, driving the third bevel gear 304 to rotate simultaneously. The third bevel gear 304 rotates, driving the stirring shaft 1405 to rotate. The rotation of the stirring shaft 1405 drives the fixed block 1406 to rotate. The rotation of the fixed block 1406 drives the brush strip 1408 to rotate. The first fixing head 1412 on the mounting block 1411 moves in the first fixing groove 1407. The rotation of the brush strip 1408 continuously moves the material, speeding up the material screening and improving the working efficiency of the device. Material of suitable particle size will gather on one side above the second screening screen 1402. The first discharge pipe 5 and the second discharge pipe 6 are opened respectively to collect the unwanted material.
[0032] Set the speed of the servo motor 4 output terminal, start the electric push-pull rod 305. The electric push-pull rod 305 drives the fourth bevel gear 306 to move until the fourth bevel gear 306 meshes with the fifth bevel gear 1206. The rotation of the fourth bevel gear 306 drives the fifth bevel gear 1206 on the rotating shaft 1205 inside the proportioning mechanism 12 to rotate simultaneously. The rotation of the rotating shaft 1205 drives the rotating disk 1201 and the limiting disk 1202 to rotate simultaneously. The rotation of the rotating disk 1201 drives the limiting post 1204 to rotate. The limiting post 1204 rotates and engages with the limiting slot 1208 on the rotating plate 1207. The movement of the limiting post 1204 drives the rotating plate 1207 to rotate. When the rotating plate 1207 rotates to a certain angle, the limiting post 1204 disengages from the limiting slot 1208, and the rotating plate 1207 stops rotating. At the same time as the rotating plate 1207 rotates, it drives the connecting shaft 1209 and the collecting mechanism 10 to rotate simultaneously. The transmission gear 1211 on the gear plate 802 meshes with the transmission gear 1211. The rotation of the transmission gear 1211 drives the transmission gear 1211 to rotate. When the rotating plate 1207 stops rotating, the storage box 1003 is located below the conveying pipe 803. At the same time, the connecting hole 807 on the gear plate 802 is connected to the connecting hole 807 on the fixed plate 806, so that the material is discharged from the inside of the screening box 1 and falls into the inside of the storage box 1003. The rotating plate 1201 and the limiting plate 1202 continue to rotate. When the material just meets the ratio, the limiting post 1204 rotates into the limiting slot 1208 again, and the rotating plate 1207 rotates again. When the rotating plate 1207 rotates again, the connecting hole 807 on the gear plate 802 is misaligned with the connecting hole 807 on the fixed plate 806, so the material will not be discharged and there will be no waste of material. At the same time, the storage box 1003 with the material rotates out, and the user can replace the storage box 1003.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
