[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties in various regions. The state stipulates that primary agricultural products refer to plants, animals, and their products obtained in agricultural activities, excluding various processed products. The grades of agricultural products are generally determined according to the appearance and size of agricultural products. Since agricultural products vary in size, their prices are also different when sold. Therefore, after harvesting, workers need to screen agricultural products of different sizes. The existing screening methods are divided into manual screening and mechanical screening. Manual screening is time-consuming and laborious, while mechanical screening usually affects the screening efficiency due to the accumulation of agricultural products at the sieve holes. Therefore, there are problems such as low screening efficiency, low accuracy, and high labor intensity. At the same time, the existing screening device for agricultural product quality inspection usually does not have the function of cleaning the equipment after screening the quality of agricultural products, which easily causes certain impacts on the service life of the equipment due to residual soil impurities, etc. For this reason, a new screening device for agricultural product quality inspection is proposed.

Specific implementation manners
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0027] Referring to Figures 1-5 , an embodiment provided by the present utility model: A new type of screening device for agricultural product quality inspection includes a base 1. One side of the top of the base 1 is fixedly provided with a first support column 2 and a dust collection chamber 3. The top of the first support column 2 is provided with a groove 4. A first motor 10 is fixedly arranged in the groove 4. The output end of the first motor 10 is fixedly connected to a first connecting rod 11. The first connecting rod 11 is hinged to a second connecting rod 12. The lower part of the second connecting rod 12 is fixedly connected to a fixed column 13. One side of the fixed column 13 away from the second connecting rod 12 is fixedly connected to a protective cover 14. The protective cover 14 is fixedly connected to a screening box 7. Four groups of holes 8 are provided at the bottom of the screening box 7. Thus, the screening box 7 drives the agricultural products to shake, thereby screening out the sizes of the agricultural products. For example, the top screening plate 21 collects the agricultural products with the largest volume, the middle screening plate 21 collects the agricultural products with a medium volume, and the bottom screening plate 21 collects the agricultural products with a small volume. Therefore, the screening efficiency of the agricultural products can be accelerated, which is convenient for hierarchical screening and improves the screening efficiency.
[0028] A spherical ball 6 is fixedly installed on one side of the screening box 7 away from the protective cover 14. The spherical ball 6 is placed in the first circular groove 5. A second support column 26 is fixedly connected to the side of the first circular groove 5 away from the spherical ball 6. The second support column 26 is installed on the base 1. The first circular groove 5 and the second support column 26 are located in the dust collection chamber 3. A second motor 23 is arranged in the protective cover 14. The output end of the second motor 23 is fixedly connected to a rotating shaft 16. A sliding groove 17, a limiting groove 24 and a second circular groove 25 are arranged in the rotating shaft 16. A cylinder 18 is arranged in the second circular groove 25. The output end of the cylinder 18 is fixedly connected to a slider 19. Brushes 20 are fixedly installed on both sides of the slider 19. The brushes 20 slide in the limiting groove 24. The slider 19 slides in the sliding groove 17. The rotating shaft 16 penetrates through and is rotatably connected to the inside of the screening box 7. An annular groove 9 is arranged on the inner wall of the screening box 7. A screening plate 21 is installed on the annular groove 9. Sieve holes 22 are arranged on the screening plate 21. There are three groups of screening plates 21. An inlet 15 is arranged on one side of the top of the screening box 7. A fixed groove 29 is arranged on one side of the screening box 7. A door panel 28 is slidably connected in the fixed groove 29. A bolt 27 is arranged on the fixed groove 29. The sliding groove 17 is communicated with the limiting groove 24. The sliding groove 17 is communicated with the second circular groove 25. There are six groups of brushes 20 and limiting grooves 24. There are three groups of bolts 27 and door panels 28. By arranging the brushes 20, the soil and impurities on the screening plate 21 of the device are cleaned, which solves the problem of damage caused by the adhesion of soil and impurities in the existing screening device for agricultural product quality detection and prolongs the service life of the equipment.
[0029] Working principle: During operation, first start cylinder 18. Cylinder 18 drives slider 19 to move within chute 17, and then drives brush 20 on slider 19 to move upward within limit slot 24, causing brush 20 to move away from screening plate 21. Then, the agricultural products to be screened are fed into screening box 7 through feed inlet 15. Start motor 10 in groove 4. The output end of motor 10 drives connecting rod 11 to rotate, and then drives connecting rod 12 on connecting rod 11 to move around motor 10, thereby driving the movement of protective cover 14 on fixed column 13. Protective cover 14 drives sphere 6 to move around circular groove 1 through screening box 7, and then screening box 7 drives the agricultural products to shake, so as to screen out the sizes of the agricultural products. For example, the top screening plate 21 collects the agricultural products with the largest volume, the middle screening plate 21 collects the agricultural products with moderate volume, and the bottom screening plate 21 collects the agricultural products with small volume, which can improve the screening efficiency of agricultural products, facilitate classification screening and improve the screening efficiency. At the same time, the soil on the surface of the agricultural products is removed during the screening process. The soil impurities are gradually transmitted to dust collection chamber 3 through sieve holes 22. After the screening is completed, by unscrewing bolt 27, sliding door panel 28 moves away from fixed slot 29 to expose the discharge port, and the agricultural products are discharged for the next process. Then, it is necessary to clean the soil impurities attached to screening plate 21. Start cylinder 18. Cylinder 18 drives slider 19 to move within chute 17, and then drives brush 20 on slider 19 to move downward within limit slot 24, causing brush 20 to move closer to screening plate 21. Then start motor 23. Motor 23 drives rotating shaft 16 to rotate, and then drives brush 20 to rotate, so as to clean the soil impurities attached to screening plate 21. The attached soil impurities fall into dust collection chamber 3 along hole 8 through sieve holes 22. By setting brush 20, the soil impurities on screening plate 21 of the device are cleaned, solving the problem of damage caused by the attachment of soil impurities in the existing screening device for agricultural product quality detection and extending the service life of the equipment.
[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
