Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Refer to Figures 1-4 , a screening device for quick-frozen fruit and vegetable products, including a bottom plate 1. Four chutes 2 are arranged on the upper part of the bottom plate 1. Sliders 3 are slidably arranged in the four chutes 2. The chutes 2 limit the movement of the sliders 3. The inner wall of the slider 3 is fixedly connected with a baffle 4. The lower part of the baffle 4 is fixedly connected with a screening plate 5. The screening plate 5 is arranged between the two baffles 4. Four partitions 6 are fixedly connected to the upper part of the screening plate 5. A collection box 7 is arranged below the screening holes in the screening plate 5. The collection box 7 is fixedly connected to the upper part of the bottom plate 1. Screening mechanisms are arranged on both sides of the collection box 7 relative to the upper part of the bottom plate 1;

[0022] The screening mechanism includes a fixing block 8. A first spring 18 is fixedly connected to the upper part of the fixing block 8. The upper part of the first spring 18 is fixedly connected with a connecting plate 19. The upper part of the connecting plate 19 is fixedly connected to the lower part of the screening plate 5. When the screening mechanism operates, through the compression and tension of the two first springs 18, the screening plate 5 moves up and down repeatedly to reduce vibration, and then the friction of the slider 3 in the chute 2 is used to offset the elastic amplitude of the first spring 18 to avoid shaking;

[0023] The screening mechanism further includes a fixing plate 9. The fixing plate 9 is used to fix the driving motor 10. The fixing plate 9 is fixedly connected to the upper part of the bottom plate 1. The fixing plate 9 is fixedly connected with a driving motor 10. The driving end of the driving motor 10 is fixedly connected with a driving gear 11;

[0024] The fixing block 8 is provided with a through hole. A rotating shaft 13 is rotatably connected in the through hole. A rotating gear 12 is fixedly connected to the end of the rotating shaft 13. The rotating gear 12 and the driving gear 11 are meshed and connected. When the driving gear 11 rotates, it will drive the rotating gear 12 to rotate, and then the rotating shaft 13 rotates with the rotation of the rotating gear 12;

[0025] The rotating shaft 13 is fixedly connected with a rotating blade 14. When the rotating shaft 13 rotates, the rotating blade 14 will rotate around the rotating shaft 13. The rotating blade 14 is rotatably connected with a rocker 15. When the rotating blade 14 rotates around the rotating shaft 13, it drives one end of the rocker 15 to perform a circular motion with the rotating shaft 13 as the center. The upper part of the rocker 15 is rotatably connected with a fixed column 16. When one end of the rocker 15 performs a circular motion with the rotating shaft 13 as the center, the fixed column 16 is restricted by the slider 3 arranged in the chute 2 and performs a linear up-and-down motion. The upper part of the fixed column 16 is fixedly connected with a fixed cylinder 21. Inside the fixed cylinder 21, a second spring 20 is fixedly connected. The upper part of the second spring 20 is fixedly connected with a push rod 17. When the fixed cylinder 21 moves upward, the second spring 20 will be compressed. When it is compressed to a certain extent, it will push the push rod 17 to move upward. The upper part of the push rod 17 is connected to the lower part of the screening plate 5;

[0026] The partition plate 6 is arranged between the screening holes in the screening plate 5 and can screen different kinds of quick-frozen fruit and vegetable products at the same time. Two first springs 18 are symmetrically distributed on the fixed block 8.

[0027] The functional principle of the present utility model can be described through the following operation method:

[0028] When quick-frozen fruit and vegetable products need to be screened, the quick-frozen fruit and vegetable products are placed in the space surrounded by the baffle 4, the screening plate 5 and the partition plate 6. Then the driving motor 10 is started, so that the driving motor 10 drives the driving gear 11 to rotate, and the rotating gear 12 meshed with the driving gear 11 rotates. Then the rotation of the rotating gear 12 drives the rotating shaft 13 to rotate in the fixed block 8. When the rotating gear 12 rotates, the rotating blade 14 rotates around the rotating shaft 13 as the center, and the other end of the rotating blade 14 drives the rocker 15 to perform repeated movements;

[0029] When the rocker 15 performs repeated movements, the fixed column 16 rotatably connected to the upper part will perform repeated up-and-down movements, so that the second spring 20 will move up and down, thereby driving the push rod 17 to perform repeated up-and-down movements. Through the compression and tension of the two first springs 18 and one second spring 20, the screening plate 5 performs repeated up-and-down movements to reduce vibration and avoid damage to the quick-frozen fruit and vegetable products caused by mechanical vibration screening.

[0030] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
