[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6 , the utility model provides a technical solution:

[0027] A seed screening device for garlic planting comprises a box body 1, a door panel 2 is hingedly connected to one side of the box body 1, a handle 3 is fixedly connected to the outer surface of the door panel 2, a feeding port 5 is provided on the top of the box body 1, a motor 4 is fixedly connected to the top of the box body 1, a rotating shaft 6 is fixedly connected to the output shaft of the motor 4, the rotating shaft 6 is rotatably connected to the inner cavity of the box body 1, a plurality of rotating blades 14 are fixedly connected to the outer surface of the rotating shaft 6 at equal intervals, two screening frames 7 are equidistantly installed in the inner cavity of the box body 1, the two screening frames 7 have the same structure, sieve holes 16 are equidistantly provided in the inner cavity of the screening frame 7, an elastic sheet 21 is fixedly connected to the bottom of the sieve hole 16, an adjusting device is provided in the inner cavity of the screening frame 7, the adjusting device comprises a moving plate 17, the moving plate 17 is slidably connected to the inner cavity of the screening frame 7, a fixing ring 22 is fixedly connected to the top of the moving plate 17, control plates 18 are slidably connected to the two sides of the inner cavity of the moving plate 17, springs 19 are fixedly connected to the opposite surfaces of the control plate 18, and an adjusting hole 20 is provided on the outer surface of the screening frame 7.

[0028] By adopting the above technical solution, when the operator wants to screen the garlic, he pulls the handle 3, so that the handle 3 drives the door panel 2 to rotate, so that the operator can adjust the diameter of the sieve holes 16 of the two screening frames 7. The operator pinches the control plate 18 on the outer surface of the screening frame 7 with his hand, so that the two control plates 18 are relatively close, and gradually compresses the spring 19, and then pushes the control plate 18 to slide on the outer surface of the central axis of the adjustment hole 20, and the control plate 18 drives the moving plate 17 to move upward synchronously. Since the adjustment hole 20 is in the shape of a "king", after the operator has finished adjusting, the control plate 18 is released, so that the compressed spring 19 clamps the control plate 18 at the two ends of the corresponding position of the adjustment hole 20, and the moving plate 17 drives the fixed plate 17 to move upward synchronously. The fixed ring 22 moves upward, so that the fixed ring 22 gradually squeezes the bottom of the elastic sheet 21, so that the bottom of the elastic sheet 21 shrinks toward the circumference center, thereby controlling the diameter of the bottom screening of the sieve hole 16. Then the operator pours the garlic into the inner cavity of the box body 1 through the feed port 5, and the garlic falls to the top of the screening frame 7. The operator turns on the motor 4, so that the motor 4 drives the rotating leaves 14 to rotate, and the rotating leaves 14 continuously push the garlic to move on the top of the screening frame 7. When passing through the sieve hole 16, the garlic smaller than the adjusted bottom diameter of the sieve hole 16 will fall to the bottom of the screening frame 7, and the garlic that meets the standard will be retained at the top of the screening frame 7, realizing the function of graded screening, and the operation is simple, which is convenient for the operator to screen the garlic and improves the production efficiency.

[0029] Specifically, Figure 2 , Figure 3 , Figure 6As shown, bristles 15 are fixedly connected to the bottom of the rotating blade 14, an inclined plate 9 is fixedly connected to the bottom of the inner cavity of the box body 1, and the inclined plate 9 is inclined with the horizontal plane. A collecting box 8 is provided at the bottom of the inclined plate 9, and the collecting box 8 is fixedly connected to the top of the protection box 10. A fan 25 is provided in the inner cavity of the protection box 10, and the fan 25 is fixedly connected to the bottom outer surface of the rotating shaft 6. Waste boxes 11 are fixedly connected to both sides of the protection box 10, and a filter screen 24 is fixedly connected to the side of the waste box 11 close to the protection box 10. The waste box 11 is connected to the inner cavity of the protection box 10, and the other side of the waste box 11 is fixedly connected to the air inlet pipe 12, and the other end of the air inlet pipe 12 is fixedly connected to the inner wall of the screening frame 7. The front side of the protection box 10 is fixedly connected to the air outlet pipe 13, and one end of the air outlet pipe 13 is fixedly connected to a one-way valve 23. The one-way valve 23 is used to control the one-way air outlet of the air outlet pipe 13, and the waste box 11 is connected to the inner cavities of the air inlet pipe 12 and the air outlet pipe 13 respectively.

[0030] By adopting the above technical solution, when the rotating shaft 6 drives the rotating blade 14 to rotate, the bristles 15 at the bottom of the rotating blade 14 continuously clean the bottom of the screening frame 7 to prevent the garlic skin and the soil and other impurities carried by the garlic from clogging the sieve hole 16 and affecting the screening efficiency. At the same time, the rotating shaft 6 drives the fan 25 at the bottom to rotate, and the fan 25 rotates in the protection box 10 to generate negative pressure. The protection box 10 draws external air through the air inlet pipe 12, so that the air inlet pipe 12 draws the garlic skin and impurities into the waste box 11, thereby preventing the garlic from mixing with the skin and impurities to affect the accuracy of subsequent screening, and reducing the operator's rear The difficulty of continuing to screen garlic is increased. The filter screen 24 on one side of the waste box 11 can prevent the skin and impurities from entering the inner cavity of the protection box 10. The air sucked into the protection box 10 is discharged from the air outlet pipe 13. After screening from the two screening frames 7, the garlic that does not meet the standards falls from the screening frame 7 to the top of the inclined plate 9, and slides along the inclined surface of the inclined plate 9 to the collection box 8, which is convenient for the operator to screen. At the same time, the air outlet pipe 13 blows air towards one side of the collection box 8, and blows the skin and impurities falling from the screening frame 7 to the other side of the collection box 8, preventing the skin and impurities from falling to the top of the collection box 8, thereby ensuring the cleanliness of the collection box 8.

[0031] Working principle: when the operator wants to screen the garlic, he pulls the handle 3 so that the handle 3 drives the door panel 2 to rotate, so that the operator can adjust the diameter of the bottom of the sieve holes 16 of the two screening frames 7. The operator pinches the control plate 18 on the outer surface of the screening frame 7 with his hand so that the two control plates 18 are relatively close to each other and gradually compresses the spring 19. Then, the control plate 18 is pushed to slide on the outer surface of the central axis of the adjustment hole 20. The control plate 18 drives the movable plate 17 to move upward synchronously. The control plate 18 is released so that the compressed spring 19 clamps the control plate 18 at the two ends of the corresponding position of the adjustment hole 20. The movable plate 17 drives the fixing ring 22 to move upward so that the fixing ring 22 gradually squeezes the bottom of the elastic sheet 21 so that the bottom of the elastic sheet 21 shrinks toward the center of the circumference, thereby controlling the screening diameter of the sieve holes 16. Then, the operator pours the garlic into the inner cavity of the box body 1 through the feed port 5. The garlic falls to the top of the screening frame 7. The operator turns on the motor 4 so that the motor 4 drives the rotating blade 14 to rotate, and the rotating blade 14 continuously pushes the garlic to move on the top of the screening frame 7. The bristles 15 at the bottom of the rotating blade 14 continuously clean the bottom of the screening frame 7. When passing through the sieve hole 16, the garlic smaller than the diameter of the top sieve hole 16 will fall to the bottom of the screening frame 7, and the garlic that meets the standard will be retained at the top of the screening frame 7. At the same time, the rotating shaft 6 drives the fan 25 at the bottom to rotate, and the fan 25 rotates in the protection box 10 to generate negative pressure. The protection box 10 draws external air through the air inlet pipe 12, so that the air inlet pipe 12 draws the garlic skin and impurities into the waste box 11, and the air sucked into the protection box 10 is discharged from the air outlet pipe 13. The garlic that does not meet the standard falls from the screening frame 7 to the top of the inclined plate 9, and slides along the inclined surface of the inclined plate 9 into the collection box 8. The air outlet pipe 13 blows air to one side of the collection box 8, and blows the skin and impurities falling from the screening frame 7 to the other side of the collection box 8, so as to prevent the skin and impurities from falling to the top of the collection box 8 and ensure the cleanliness of the collection box 8.
