[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a rice production screening device, including a workbench 1. A motor 2 is fixedly connected to the lower surface of the workbench 1. A first roller 3 is fixedly installed at the output end of the motor 2. The outer wall of the first roller 3 is rotatably connected to the inside of the workbench 1. A conveyor belt 4 is installed on the outer wall of the first roller 3. A second roller 5 is installed on the inner wall of the conveyor belt 4. The outer wall of the second roller 5 is rotatably connected to the inside of the workbench 1. A rotating shaft 6 is fixedly connected to the inside of the rotating shaft 6. A rotating rod 7 is rotatably connected to the outer wall of the rotating rod 7. A connecting rod 8 is fixedly connected to the inside of the rotating rod 7. A fixing block 9 is rotatably connected to the outer wall of the connecting rod 8. A screen frame 10 is fixedly connected to the inside of the fixing block 9. A roller 11 is fixedly connected to the outer wall of the fixing block 9. The outer wall of the roller 11 is slidably connected to the inner wall of the workbench 1. A support assembly is provided on the lower surface of the workbench 1 for auxiliary fixation.

[0024] Specifically, the workbench 1 fixes the motor 2, which in turn causes the conveyor belt 4 to rotate via the rotation of the first roller 3, which in turn drives the second roller 5 to rotate. The second roller 5 fixes the rotating shaft 6, which in turn causes the connecting rod 8 to slide via the rotation of the rotating rod 7, which in turn causes the fixed block 9 to slide. The fixed block 9 fixes both the screen frame 10 and the roller 11, allowing the roller 11 to slide on the inner wall of the workbench 1 through the sliding of the fixed block 9. The continuous reciprocating motion of the screen frame 10 allows for the reciprocating sliding screening of the rice, ensuring that the rice is evenly distributed and fully screened inside the screen frame 10, reducing the accumulation between grains, and making it easier for the rice to pass through the screen frame 10, thereby improving screening efficiency.

[0025] Reference Figure 1The support assembly includes a base 12, the upper surface of which is fixedly connected to the lower surface of the workbench 1, and a connecting plate 13 is fixedly connected to the outer wall of the base 12.

[0026] Specifically, the base 12 provides stable support for the workbench 1 and supports the connecting plate 13, ensuring the stability of the screening operation.

[0027] Reference Figure 3 and Figure 4 A screen 14 is fixedly connected to the outer wall of the connecting plate 13. A feeding hopper 15 is fixedly connected to the lower surface of the screen 14. A fixing ring 16 is fixedly connected to the outer wall of the feeding hopper 15. The outer wall of the fixing ring 16 is fixedly connected to the outer wall of the connecting plate 13. A support plate 17 is fixedly connected to the outer wall of the connecting plate 13. A support block 18 is fixedly connected to the upper surface of the support plate 17. A cylinder 19 is fixedly connected to the upper surface of the support block 18. A discharge hopper 20 is fixedly connected to the output end of the cylinder 19. A sealing cover 21 is rotatably connected to the lower surface of the discharge hopper 20. The lower surface of the sealing cover 21 is slidably connected to the upper surface of the support plate 17. A sliding plate 22 is fixedly connected to the upper surface of the discharge hopper 20. A limiting plate 23 is slidably connected to the outer wall of the sliding plate 22. A connecting block 24 is fixedly connected to the outer wall of the limiting plate 23. The outer wall of the connecting block 24 is fixedly connected to the outer wall of the connecting plate 13. A connecting hopper 25 is slidably connected to the upper surface of the sliding plate 22. The upper surface of the connecting hopper 25 is fixedly connected to the lower surface of the discharge hopper 15.

[0028] Specifically, the connecting plate 13 fixes the screen 14, which is finer than the screen frame 10 for secondary screening. The fixing ring 16, fixed to the outer wall of the connecting plate 13, fixes the feeding hopper 15. The screened rice enters the connecting hopper 25. The support plate 17, fixed to the outer wall of the connecting plate 13, fixes the support block 18. The support block 18 fixes the cylinder 19, which allows the sealing cover 21 to slide via the sliding of the discharge hopper 20. The support plate 17 also supports the sealing cover 21. The sealing cover 21 acts as a limit, blocking the rice inside the discharge bucket 20 when it is on the upper surface of the support plate 17. The discharge bucket 20 fixes the slide plate 22, and the connecting block 24 is fixed to the outer wall of the connecting plate 13, which in turn fixes the limiting plate 23, allowing the slide plate 22 to slide through the limiting plate 23. When the slide plate 22 slides, it also blocks the lower surface of the connecting bucket 25. When the sealing cover 21 slides out of the support plate 17, the rice will flow out from the inside of the discharge bucket 20, ensuring that the weight of the rice is consistent each time it is discharged.

[0029] Working Principle: When this equipment is needed, the fragrant rice to be screened is placed inside the sieve frame 10. The motor 2 on the lower surface of the workbench 1 is started. The motor 2 drives the first roller 3 to rotate. The rotation of the first roller 3 drives the second roller 5 on the inner wall to rotate via the conveyor belt 4. When the second roller 5 rotates, it drives the rotating rod 7 to rotate via the rotating shaft 6. During the rotation of the rotating rod 7, it drives the fixed block 9 to slide via the internal connecting rod 8. The fixed block 9 drives the inner sieve frame 10 to slide, thereby causing the outer roller 11 to slide on the inner wall of the workbench 1. Thus, the rice inside is screened by the sliding of the sieve frame 10, achieving the effect of even distribution and thorough screening of the rice inside the sieve frame 10. The screened rice falls into the finer sieve 14 for secondary screening and enters the connecting bucket 2 through the feeding bucket 15. The rice is stored inside the 5-connecting bucket. When it is necessary to repackage the rice, the rice inside the connecting bucket 25 will enter the discharge bucket 20. The cylinder 19 on the upper surface of the support block 18 will be activated, and the cylinder 19 will push the discharge bucket 20 to slide. When the discharge bucket 20 slides, it will drive the sliding plate 22 on the upper surface to slide on the inner wall of the limiting plate 23. At the same time, the sliding of the discharge bucket 20 will drive the sealing cover 21 on the lower surface to slide on the upper surface of the support plate 17. After the sealing cover 21 slides out of the upper surface of the support plate 17, the rice can be poured out for repackaging, so as to ensure that the amount of rice repackaged each time is consistent, making the repackaging process more standardized. This equipment can not only achieve the effect of evenly distributing the rice and fully screening it, improving the screening efficiency, but also achieve quantitative repackaging of the screened rice, making the packaging more standardized and improving product quality.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
