Technical Field
[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a novel organic corn seed size grading and screening device. Background Technology
[0002] Corn seeds are the propagation material for corn plants and are the foundation of corn cultivation. Corn seeds need to be screened to ensure that the selected seeds are of uniform size and shape. This helps to ensure the uniformity of corn plant growth, thereby improving the quality of corn.
[0003] Screeners are typically equipped with sieve holes of different sizes. When corn seeds pass through the sieve, seeds and impurities of different sizes are separated according to the size of the sieve holes. Larger seeds and impurities are left on the sieve surface, while smaller seeds pass through the sieve holes and fall into the collection area below. Screeners are usually equipped with a vibration device to make the sieve surface vibrate, which helps the seeds and impurities move and separate on the sieve surface.
[0004] However, the screens of some existing corn seed grading and screening devices are not easy to disassemble, and it is not convenient to replace screens with different mesh sizes to adjust the size of the corn seeds to be screened. In addition, the screen plates of some screening devices are exposed, which causes impurities and dust mixed in the seeds to be dispersed into the air during the screening process. This not only easily mixes into the collected seed box, but also affects the breathing of the staff and is inconvenient to clean. Therefore, a new type of organic corn seed size grading and screening device is proposed to solve the above problems. Utility Model Content

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] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6This utility model provides an embodiment of a novel organic corn seed size grading and screening device, comprising a support body 1, a sorting box 2 fixedly connected to the middle of the support body 1, a feeding assembly provided at the top left of the sorting box 2, the feeding assembly being used to prevent dust and impurities from drifting out from the feeding port during screening, three slide rails 14 fixedly connected at equal distances at both the front and rear ends of the sorting box 2, vibrating screen plates 15 slidably connected between the three sets of front and rear slide rails 14, connecting plates 16 fixedly connected to the left ends of the three vibrating screen plates 15, limiting plates 17 fixedly connected to the left ends of the connecting plates 16, limiting grooves 18 formed at the top of each limiting plate 17, and handles 19 fixedly connected to the left ends of each limiting plate 17, and fixing plates 20 fixedly connected to the upper ends of the limiting plates 17 on the left side of the sorting box 2. The top of the fixed plate 20 is rotatably connected to a knob 21, and the bottom of the knob 21 is fixedly connected to a threaded post 22. The outer side of the threaded post 22 is threadedly connected to a limit block 23, which engages with the adjacent limit groove 18. The front end of the support body 1 is provided with an air blowing assembly, which is used to blow dust to the rear of the sorting box 2. The rear end of the sorting box 2 is provided with a dust suction assembly, which is used to collect dust at the bottom of the sorting box 2. The right end of the sorting box 2 is fixedly connected to a sorting box 24 on the upper right side of the vibrating screen plate 15. The rear end of the upper sorting box 24 is fixedly connected to a discharge plate 1 25, the front end of the middle sorting box 24 is fixedly connected to a discharge plate 26, and the right end of the bottom sorting box 24 is fixedly connected to a discharge plate 3 27. The bottom end of the sorting box 2 is provided with an outlet 37.
[0027] The support body 1 supports the entire sorting box 2. Corn seeds can be fed into the sorting box 2 via the feeding assembly. The vibrating screen plate 15 is easily installed inside the sorting box 2 by sliding it onto the two front and rear slide rails 14 on the same side. Rotating the knob 21 on top causes the threaded column 22 to move the limiting block 23 downwards. The limiting block 23 engages with the corresponding limiting groove 18, preventing it from moving out when the vibrating screen plate 15 vibrates and sorts the corn seeds. The upper vibrating screen plate 15 intercepts larger corn seeds at the top. The size of the corn seeds decreases from top to bottom, and then flows out of the sorting box 2 through the discharge plate 1 25. The remaining corn seeds fall onto the middle vibrating screen plate 15, which intercepts medium-sized corn seeds and causes them to flow out through the discharge plate 2 26. The remaining corn seeds fall onto the bottom vibrating screen plate 15. Corn seeds larger than the screen holes of the bottom vibrating screen plate 15 flow out of the support body 1 through the discharge plate 3 27. The air blowing component and the dust suction component work together to suck impurities into the bottom of the sorting box 2. The smaller, unqualified corn seeds are mixed and flow out through the outlet 37.
[0028] Reference Figure 1 and Figure 2The feeding assembly includes a feeding hopper 3 and a motor 9. The bottoms of the feeding hopper 3 and the motor 9 are fixedly connected to the top of the sorting box 2. The top of the sorting box 2 is provided with cover plates 4 on both the front and rear sides. The left and right ends of the two cover plates 4 are fixedly connected to adjacent sides of each other. The middle of the two right connecting blocks 5 is threaded with a double-acting screw 13. The front end of the double-acting screw 13 is fixedly connected to a worm gear 12. The output end of the motor 9 is fixedly connected to a rotating shaft 10. The outer side of the rotating shaft 10 is fixedly connected to a worm gear 11. The worm gear 11 is meshed with the outer end of the worm gear 12. The top of the support body 1 is fixedly connected to the front and rear of the right end of the feeding hopper 3 with a support plate 6. The double-acting screw 13 and the two support plates 6 are rotatably connected. The worm gear 12 is located at the front end of the front support plate 6. The top of the left end of the sorting box 2 is fixedly connected to the front and rear sides with a support plate 7. The two support plates 7 are rotatably connected to each other. The slide rod 8 is slidably connected to the two left connecting blocks 5.
[0029] The motor 9 drives the rotating shaft 10 and worm gear 11 to rotate. Since the worm gear 11 and worm wheel 12 are meshed, the rotation of the worm gear 11 will drive the worm wheel 12 to rotate. The rotation of the worm wheel 12 will cause the bidirectional lead screw 13 to rotate synchronously, thereby driving the cover plate 4 to move in the opposite direction. When the adjacent sides of the cover plate 4 are in contact, it can prevent dust from floating out of the feed hopper 3. When the adjacent sides of the cover plate 4 are separated, corn seeds can be added into the feed hopper 3. The sliding rod 8 makes the movement of the cover plate 4 more stable.
[0030] Reference Figure 3 and Figure 4 The air blowing assembly includes an air pump 28, with a support base 29 fixedly connected to the bottom of the outer end of the air pump 28. The rear end of the support base 29 is fixedly connected to the front end of the sorting box 2. A main air pipe 30 is fixedly connected to the output end of the air pump 28. Three branch air pipes 31 are fixedly connected at equal intervals to the rear end of the outer end of the main air pipe 30. Air blowing plates 32 are fixedly connected to the rear ends of each of the three branch air pipes 31. The three air blowing plates 32 are all located inside the sorting box 2 and are all located on top of adjacent vibrating screen plates 15. The dust collection assembly includes a centrifugal pump 33. A support base 39 is fixedly connected to the bottom of the outer end. The front end of the support base 39 is fixedly connected to the rear end of the sorting box 2. A main suction pipe 34 is fixedly connected to the input end of the centrifugal pump 33. Three branch suction pipes 35 are fixedly connected at equal intervals to the front of the outer end of the main suction pipe 34. A feed plate 36 is fixedly connected to the front end of each of the three branch suction pipes 35. A discharge pipe 38 is fixedly connected to the output end of the centrifugal pump 33. The position of the feed plate 36 is located inside the sorting box 2 and corresponds to the air blowing plate 32 on the same side. The end of the discharge pipe 38 is located at the bottom end of the bottom vibrating screen plate 15.
[0031] By activating the air pump 28, external air is drawn into the main air pipe 30, and then flows through the main air pipe 30 into the three branch air pipes 31 and the corresponding air blowing plates 32, thereby allowing air to enter the interior of the sorting box 2 and blowing impurities toward the rear feed plate 36. The centrifugal pump 33 is activated, allowing impurities to enter the discharge pipe 38 through the feed plate 36, the branch suction pipe 35 and the main suction pipe 34, and then be transported by the discharge pipe 38 to the bottom of the interior of the sorting box 2, and then fall outside the sorting box 2 through the outlet 37. In addition, the air blowing plates 32 and the feed plate 36 are set above the vibrating screen plate 15, and their coordination with the vibration of the vibrating screen plate 15 helps to improve the efficiency of impurity screening and reduce the number of impurities and bad seeds contained in the seeds.
[0032] Working principle: First, corn seeds are poured into the feed hopper 3. Then, the motor 9 is started, driving the worm gear 11 to rotate, thereby moving the two cover plates 4 towards the center of the feed hopper 3, so that the opposite sides of the two cover plates 4 are in contact. Then, the three vibrating screen plates 15 screen the corn seeds. During screening, the vibrating screen plates 15 vibrate. At the same time, the air pump 28 and the centrifugal pump 33 are started, so that the air blowing plate 32 blows the lighter corn seeds and impurities toward the feed plate 36. The feed plate 36 sends them to the lower end of the bottom vibrating screen plate 15. Then, these waste seeds are removed. Dust and other particles flow out through outlet 37. Corn seeds of different sizes are sorted by the vibrating screen plate 15 with screen holes from large to small, and flow out from discharge plate 1 25, discharge plate 26 and discharge plate 3 27 respectively for collection. When it is necessary to replace the vibrating screen plate 15 with a different size of screen hole, the corresponding knob 21 can be rotated to make the threaded column 22 drive the limit block 23 to move upward, so that the limit block 23 is disengaged from the limit groove 18. Then, by holding the handle 19 and applying force to the left, the vibrating screen plate 15 can be pulled out of the sorting box 2 for replacement.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
