[0002] When harvesting wheat, in order to improve its quality, breeding and seed selection are required, which helps to ensure the quality and purity of wheat seeds, thereby increasing the yield and quality of wheat. For this purpose, a vibrating screening machine can be used. The vibrating screening machine makes the wheat seeds move on the sieve through vibration, and screens according to the differences in the size, shape and weight of the seeds. Larger seeds, impurities and pest-infected seeds will be screened out, while smaller high-quality seeds will pass through the sieve;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0020] An embodiment of the present application discloses a wheat breeding and seed selection device. Refer to Figure 1, including a screening box 1. The inner wall of the screening box 1 is provided with two screens with different mesh sizes. At the same time, a vibration motor is fixed at the lower end to facilitate the screening of wheat. A box cover 2 is arranged at the upper end of the screening box 1. The box cover 2 is snap-fitted and fixed at the upper end of the screening box 1. A feeding hopper 3 is fixedly connected to the upper end of the box cover 2, which can facilitate the pouring of wheat. An inclined plate 4 is fixedly connected to the inner wall of the feeding hopper 3. A baffle 5 is arranged on the inner wall of the feeding hopper 3. The feeding speed of wheat can be adjusted through the inclined plate 4 and the baffle 5. A plurality of tooth-bar rods 8 are fixedly connected to the body of the baffle 5. A rotating rod 9 is rotatably connected to the inner wall of the feeding hopper 3. A plurality of first gears 10 are fixedly connected to the rod body of the rotating rod 9. The rotation of the first gear 10 can drive the tooth-bar rod 8 to move. Two fixing plates 12 are fixedly connected to the outer wall of one side of the feeding hopper 3. A worm 13 is rotatably connected to the body of the fixing plate 12. A servo motor 14 is fixedly connected to one side of the fixing plate 12. The output end of the servo motor 14 is fixedly connected to the worm 13. A second gear 11 is fixedly connected to one side of the rotating rod 9. The worm 13 can drive the second gear 11 to rotate.

[0021] Refer to Figure 3 , a rotating shaft 16 is rotatably connected to the inner wall of the feeding hopper 3. A plurality of distributing rods 17 are fixedly connected to the rod body of the rotating shaft 16. A rotating motor 18 is fixedly connected to one side of the feeding hopper 3. The output end of the rotating motor 18 is fixedly connected to the distributing rod 17. The rotating motor 18 can drive the rotating shaft 16 to rotate, so that the distributing rod 17 can roll the wheat inside the feeding hopper 3 to avoid blockage of the wheat.

[0022] Refer to Figure 4 , a plurality of sliding rods 6 are fixedly connected to the lower ends of the inclined plate 4. A slider 7 is slidably connected to the rod body of the sliding rod 6. The upper surface of the baffle 5 is slidably connected to a plurality of sliders 7. The baffle 5 can slide at the lower end of the inclined plate 4 through the sliding rod 6 and the slider 7.

[0023] Refer to Figure 4 , limiting grooves are provided on both inner walls of the feeding hopper 3. Limiting wheels 15 are rotatably connected to both outer walls of the baffle 5.

[0025] The implementation principle of a wheat breeding and seed selection device in an embodiment of this application is as follows: When in use, wheat is poured into the interior of the screening box 1 through the feed hopper 3. The worm 13 is driven to rotate by the servo motor 14, so that the worm 13 can drive the second gear 11 to rotate. When the second gear 11 rotates, it can drive a plurality of first gears 10 to rotate through the rotating rod 9. The first gear 10 and the toothed rod 8 are engaged with each other, so that the first gear 10 drives the toothed rod 8 to move, adjusting the degree between the baffle 5 and the inclined plate 4, adjusting the area of the discharge port inside the feed hopper 3, thereby controlling the feeding speed of the wheat entering the interior of the screening box 1. At the same time, the rotating motor 18 can be started. The rotating motor 18 can drive the rotating shaft 16 to rotate, so that the material distributing rod 17 can roll the wheat inside the feed hopper 3 to avoid wheat blockage. The screening box 1 is driven to vibrate by the vibration motor at the lower end of the screening box 1, thereby screening and separating the wheat.
