Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This invention provides a seed screening machine for improving wheat's resistance to diseases and pests, such as... Figure 1-5 As shown, the seed screening machine for improving wheat disease and pest resistance includes a screening machine body 1. A feeding hopper 3 is provided on the upper right side of the screening machine body 1, and a first discharge port 4 is provided on the lower side of the screening machine body 1. A secondary screening box 5 is fixedly installed on the left side of the screening machine body 1, and a second discharge port 6 is provided at the lower end of the secondary screening box 5. A fan box 7 is fixedly installed on the right side of the screening machine body 1. A fan blade 8 is rotatably installed inside the fan box 7. A motor 9 is fixedly installed on the right side of the fan box 7. The output shaft of the motor 9 is fixedly connected to the fan blade 8. A rotating shaft 10 is fixedly installed on the left side of the fan blade 8. A roller 11 is fixedly installed on the left end of the rotating shaft 10 above the first discharge port 4. A drive component for moving wheat seeds is provided on the rotating shaft 10.

[0027] During the screening process, wheat seeds first enter the screening machine body 1 through the feeding hopper 3, and the output shaft of the motor 9 drives the fan blade 8 to rotate, thereby performing air separation on the wheat seeds. At the same time, the rotation of the fan blade 8 drives the drive component to move the weight of the wheat entering the drum 11, which helps to distribute the seeds evenly during the screening process and improves the accuracy and efficiency of screening. During the screening process, unripe seeds, small seeds and impurities in the seeds are effectively removed, while plump large seeds are retained.

[0028] Support frames 2 are fixedly installed at both ends of the screening machine body 1, and the lower ends of the two sets of support frames 2 are in contact with the ground.

[0029] The design of the support frame 2 enhances the stability of the entire screening machine body 1, preventing it from shaking or tilting during the screening process, thus ensuring the accuracy and safety of the screening. At the same time, the close fit between the support frame 2 and the ground facilitates the fixing and movement of the screening machine, improving the practicality and flexibility of the equipment.

[0030] A second baffle plate 13 is fixedly installed on the left end of the rotating shaft 10. The second baffle plate 13 is located inside the secondary screening box 5. The diameter of the second baffle plate 13 is the same as the inner wall size of the secondary screening box 5. The second baffle plate 13 is attached to the mesh plate at the connection between the lower inner wall of the secondary screening box 5 and the second discharge port 6.

[0031] During the screening process, the rotation of the second baffle 13 not only helps to distribute wheat seeds evenly, but also prevents seeds from clogging the screen, ensuring smooth screening. At the same time, the fit design between the second baffle 13 and the screen effectively prevents wheat seeds from being missed during the screening process, further improving the accuracy of screening. Furthermore, the unripe seeds, small seeds, and impurities removed by the air separation are screened again in the secondary screening box 5, allowing the unripe seeds and small seeds to be recycled.

[0032] The drive assembly includes a first deflector plate 12 and a mounting bracket 14. The first deflector plate 12 is rotatably sleeved on the rotating shaft 10. The mounting bracket 14 is fixedly installed inside the left end of the screening machine body 1. An external gear ring 15 is fixedly installed on the left end of the rotating shaft 10. Multiple sets of gears 16 are rotatably installed on the right side of the mounting bracket 14. An internal gear ring 17 is sleeved on the multiple sets of gears 16. The multiple sets of gears 16 mesh with the teeth on the outer wall of the external gear ring 15 and the teeth on the inner wall of the internal gear ring 17, respectively. The internal gear ring 17 is fixedly connected to the first deflector plate 12.

[0033] The output shaft of motor 9 drives the rotating shaft 10 to rotate, and simultaneously drives the outer gear ring 15 to rotate. The multiple sets of gears 16 rotatably mounted on the mounting bracket 14 drive the inner gear ring 17 to rotate. The rotation of the inner gear ring 17 further drives the first deflector 12 to rotate on the rotating shaft 10, so that the first deflector 12 and the roller 11 rotate in opposite directions. This design not only realizes continuous deflection of wheat seeds, but also ensures the stability and uniformity of deflection, further improving the efficiency and accuracy of screening.

[0034] A cover plate 18 is rotatably installed on the left side of the secondary screening box 5. The lower end of the cover plate 18 is consistent with the arc shape of the mesh plate on the lower inner wall of the secondary screening box 5.

[0035] Rotate the cover plate 18 to open, and then perform secondary screening of the unripe seeds, small seeds and impurities in the seeds that have been removed by air separation through the rotation of the second deflector plate 13 in the secondary screening box 5. Then, take out the unripe seeds and small seeds.

[0036] A chute 19 is fixedly installed inside the screening machine body 1. The chute 19 is located at the lower end of the feeding hopper 3, and the left end of the chute 19 is connected to the roller 11.

[0037] Wheat seeds are accurately fed from the hopper 3 into the drum 11 via the chute 19, so that the drum 11 can screen the wheat seeds.

[0038] The outer wall of the first deflector plate 12 is in contact with the inner wall of the roller 11, and the first deflector plate 12 is located inside the roller 11.

[0039] Based on the size of the first agitator 12, it is ensured that the wheat seeds can be effectively agitated within the drum 11 when it rotates inside the drum 11.

[0040] Working principle: Wheat seeds are fed into the screening machine body 1 from the feeding hopper 3 and slide into the drum 11 from the chute 19. Then, the motor 9 is started, and the output shaft of the motor 9 drives the fan blade 8 to rotate in the fan box 7, thereby performing air separation on the wheat seeds in the drum 11. Unripe seeds, small seeds, and impurities in the seeds are effectively removed and blown into the secondary screening box 5, while plump large seeds are retained and discharged from the first discharge port 4. At the same time, the rotation of the fan blade 8 drives the rotating shaft 10 to rotate, which in turn drives the outer gear ring 15 to rotate. Through the multiple sets of gears 16 rotatably mounted on the mounting frame 14, the inner gear ring 17 is driven to rotate. The rotation of the inner gear ring 17 further drives the first deflector plate 12. The rotating shaft 10 rotates in opposite directions, causing the first agitator 12 and the drum 11 to rotate in opposite directions. This enables continuous agitation of wheat seeds within the drum 11, ensuring the stability and uniformity of the agitation. Simultaneously, the rotation of the shaft 10 drives the rotation of the second agitator 13. The rotation of the second agitator 13 agitates the unripe seeds, small seeds, and impurities in the seeds within the secondary screening box 5. The rotation of the second agitator 13 agitates the unripe seeds, small seeds, and impurities in the seeds for secondary screening within the secondary screening box 5, allowing the unripe seeds and small seeds to be recycled. When it is necessary to remove the unripe seeds and small seeds after screening in the secondary screening box 5, the cover plate 18 can be rotated to open.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
