Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0024] Please refer to Figures 1-3 , the present utility model provides a technical solution: a screening device with an anti-blocking function, including a screening housing 1, a vibration motor is installed at the lower end of the screening housing 1, and a screening mesh 13 is welded inside the screening housing 1;

[0025] The anti-blocking component is arranged on the screening housing 1 and the screening mesh 13. The anti-blocking component includes a connecting rod 2, a sliding rod 3, a container barrel 4 and an anti-blocking roller 12. The sliding rod 3 is welded on the screening housing 1, the container barrel 4 is welded on the connecting rod 2, the connecting rod 2 slides along the sliding rod 3, the anti-blocking roller 12 is rotatably connected to the connecting rod 2, the anti-blocking roller 12 has a plurality of cylinders, and the cylinders on the anti-blocking roller 12 are engaged with the holes on the screening mesh 13.

[0026] The surface of the connecting rod 2 is fixedly connected with a threaded sleeve 5, and the surface of the threaded sleeve 5 is threadedly connected with a threaded rod 6, and the threaded rod 6 rotates through the screening housing 1.

[0027] A motor 8 is installed on the surface of the screening housing 1 by screws, and a motor gear 9 is keyed to the output shaft of the motor 8.

[0028] The surface of the threaded rod 6 is fixedly sleeved with a gear 7, and the surface of the gear 7 meshes with the surface of the motor gear 9.

[0029] A drawer 10 slidably penetrates through the surface of the screening housing 1, and a drawer handle 11 is welded to the surface of the drawer 10.

[0030] A connecting plate 14 is fixedly connected to the surface of the container barrel 4, and a motor 15 is screw-mounted on the surface of the connecting plate 14.

[0031] The output shaft of the motor 15 rotatably penetrates through the connecting plate 14, and the output shaft of the motor 15 is fixedly sleeved with a sealing plate 16, and the sealing plate 16 can completely cover the discharge port of the container barrel 4.

[0032] When it is necessary to screen rapeseed particles of appropriate size;

[0033] First, place the rapeseed particles inside the container barrel 4. Subsequently, start the motor 15. The start of the motor 15 drives the sealing plate 16 to rotate. The rotation of the sealing plate 16 opens the container barrel 4, and the rapeseed particles inside the container barrel 4 fall onto the screening mesh 13. At the same time, start the vibration motor at the lower end of the screening housing 1 for screening.

[0034] Secondly, start the motor 8. The start of the motor 8 drives the motor gear 9 to rotate. The rotation of the motor gear 9 drives the gear 7 to rotate. The rotation of the gear 7 drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the threaded sleeve 5 to reciprocate. The reciprocating motion of the threaded sleeve 5 drives the connecting rod 2 to reciprocate. The reciprocating motion of the connecting rod 2 drives the container barrel 4 to reciprocate for feeding onto the screening mesh 13. At the same time, the reciprocating motion of the connecting rod 2 drives the anti-blocking roller 12 to move. The movement of the anti-blocking roller 12 can drive the cylinder on the anti-blocking roller 12 to push against the holes on the screening mesh 13, so that the unqualified materials stuck in the holes move to the upper end of the screening mesh 13.

[0035] By providing the anti-blocking roller 12 in the anti-blocking assembly, the anti-blocking roller 12 is in a form that can roll and mesh with the screening mesh 13, so that the anti-blocking roller 12 can move to prevent blockage along with the feeding movement of the container barrel 4. Thus, while reducing the space occupied by the anti-blocking assembly, the feeding movement of the container barrel 4 can avoid the problem of material accumulation in one place, resulting in low screening efficiency. In summary, the anti-blocking assembly can improve the screening efficiency of the screening device.

[0036] When the staff finds that the screening efficiency of the screening device is low, by starting the motor 15, the start of the motor 15 can control the opening degree of the sealing plate 16. By reducing the opening degree of the sealing plate 16, the feeding rate of the container barrel 4 is reduced, and the problem of blockage caused by the continuous high-speed feeding of the container barrel 4 resulting in rapeseed particles piling up together is avoided.

[0037] Working principle:

[0038] When it is necessary to screen rapeseed particles of appropriate size;

[0039] First, place the rapeseed particles inside the container barrel 4. Subsequently, start the motor 15. The start of the motor 15 drives the sealing plate 16 to rotate, and the sealing plate 16 opens the container barrel 4. The rapeseed particles inside the container barrel 4 fall onto the screening mesh 13. At the same time, start the vibration motor at the lower end of the screening housing 1 for screening.

[0040] Secondly, start the motor 8. The start of the motor 8 drives the motor gear 9 to rotate. The motor gear 9 drives the gear 7 to rotate. The gear 7 drives the threaded rod 6 to rotate. The threaded rod 6 drives the threaded sleeve 5 to reciprocate. The reciprocating motion of the threaded sleeve 5 drives the connecting rod 2 to reciprocate. The reciprocating motion of the connecting rod 2 drives the container barrel 4 to reciprocate for feeding onto the screening mesh 13. At the same time, the reciprocating motion of the connecting rod 2 drives the anti-blocking roller 12 to move. The anti-blocking roller 12 can drive the cylinder on the anti-blocking roller 12 to push against the holes on the screening mesh 13, causing the unqualified materials stuck in the holes to move to the upper end of the screening mesh 13.

[0041] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
