Description

Technical Field

[0001] This utility model relates to the field of seed sorting equipment technology, and in particular to a seed sorting machine conveying structure. Background Technology

[0002] Seed sorting machines are common equipment in modern agricultural production, widely used for sorting, screening, and packaging seeds of different types and sizes. With the development of agricultural mechanization, traditional seed sorting machines mainly rely on vibrating screens, air-blowing, and manual sorting to classify seeds. However, these traditional methods often suffer from low efficiency, high labor costs, and complex operation, and cannot flexibly adapt to the sorting needs of different seed sizes. Currently, most seed sorting machines use a single conveyor belt or roller structure, failing to fully utilize seed characteristics for precise classification.

[0003] For example, Chinese utility model patent application number 202322378568.4 discloses a seed sorting and conveying structure that can reduce usage costs and better match the seed discharge speed with the conveyor belt speed. It includes a seed sorter and a main frame of a conveying device. The seed sorter has a feed hopper at its top and several support legs at its bottom. A discharge pipe is located at the bottom of the seed sorter, and a discharge shaft is located inside the discharge pipe. Connecting shafts are located at both ends of the discharge shaft, and a roller is located at the end of each connecting shaft. Several recessed holes are located on the discharge shaft. Several support columns are located at the bottom of the main frame of the conveying device. A conveyor belt is located inside the main frame of the conveying device. The connecting shafts and the discharge pipe are rotatably connected. The bottom end of the roller is attached to the top end of the conveyor belt, and an anti-slip pad is provided on the outer wall of the roller. There is a gap between the discharge shaft and the discharge pipe, and the gap between the discharge shaft and the discharge pipe is smaller than the diameter of the seed.

[0004] While the above solution can achieve power saving by eliminating the need for motor drive, the device is prone to slippage in actual use. Although anti-slip mats are installed to alleviate this problem, wear and tear on the seeds or anti-slip mats during the conveying process can affect the transmission process and normal use. Furthermore, in the screening of different seed sizes, it is often necessary to frequently replace the screen or adjust the screening device, which not only wastes time but also affects the working efficiency of the equipment. Therefore, a seed sorting machine conveying structure is proposed to solve the above problems. Utility Model Content

[0039] 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.

[0040] Reference Figure 1-6 This utility model provides a seed sorting machine conveying structure, including a sorting machine body 1 and a conveying frame 2. Two fixed rings 3 are fixedly connected to both sides of the conveying frame 2. Sleeve 1 4 and Sleeve 2 5 are rotatably connected to the inner walls of the two fixed rings 3, respectively. Gears 6 are fixedly connected to opposite sides of sleeve 1 4 and sleeve 2 5. A chuck 1 7 is fixedly connected to the inner wall of sleeve 2 5. A discharge cylinder 8 is connected to the opposite side of the two gears 6. A blocking cylinder 9 is slidably connected to the inner wall of the discharge cylinder 8. A rebound component is installed on one side of the blocking cylinder 9, inside sleeve 1 4, and a fixing component is installed on the other side of the blocking cylinder 9, inside sleeve 2 5. A conveying component is installed on the conveying frame 2. A feeding pipe 10 is fixedly connected to the side of the sorting machine body 1 closest to the conveying frame 2. A connecting pipe 11 is fixedly connected to one end of the feeding pipe 10. An auxiliary component is installed inside the sorting machine body 1 to assist in feeding the seeds in the connecting pipe 11. The sorting machine body 1, as the core of the entire sorting machine, contains all the key mechanical components. The conveyor frame 2, gear 6, fixed ring 3, and other components are responsible for the seed sorting operation. Through cooperation with other components, they perform the specific task of seed sorting. The fixing ring 3 ensures that the sleeve 1 4 and sleeve 2 5 can be firmly installed on the frame and rotate properly, providing axial stability and ensuring that the relevant components can rotate or move normally. The gear 6 meshes with the toothed belt 21 of the conveyor belt 19, converting the power of the conveyor belt 19 into the rotational driving force of the barrier cylinder 9. The toothed belt 21 has a dual power transmission path, which drives the conveyor belt 19 to transport seeds and simultaneously drives the barrier cylinder 9 to rotate and disperse materials. Through the coordinated use of the conveyor frame 2, gear 6, fixed ring 3, and other structures, the toothed belt 21 can be driven by the conveyor belt 19 to mesh with the gear 6, ensuring that the seeds can be stably transported through the conveyor belt 19. At the same time, it drives the seeds in the barrier cylinder 9 to rotate, ensuring the stability of the seeds during the transport process. It also makes the seeds evenly distributed on the conveyor belt 19, avoiding seed accumulation or blockage, and improving the transport efficiency.

[0041] The rebound assembly includes a mounting groove 12 on one side of the blocking cylinder 9. A spring 13 is rotatably connected inside the mounting groove 12. One end of the spring 13 is fixedly connected to a fixing plate 14. The outer wall of the fixing plate 14 is fixedly connected to the sleeve 4. When the rebound assembly adjusts the blocking cylinder 9, it compresses the spring 13 to store energy. After release, it automatically returns to the initial position. The fixing assembly includes a chuck 15 fixedly installed on one side of the sleeve 5. A push-pull button 16 is fixedly connected to the center of one side of the chuck 15. Both the chuck 15 and the chuck 7 are provided with teeth, which can be adapted to each other. The opposite sides of the chuck 15 and the chuck 7 are adapted to each other through the teeth. Through the meshing of the teeth, the blocking cylinder 9 can be self-locked during rotation, ensuring that the blocking cylinder 9 will not move randomly and ensuring stable adjustment of the seed aperture.

[0042] The conveying assembly includes a drive motor 17 fixedly mounted on one side of the conveyor frame 2. The output end of the drive motor 17 rotates through the interior of the conveyor frame 2 and is fixedly connected to a drive roller 18. A conveyor belt 19 is drivenly connected to the outer wall of the drive roller 18, and a driven roller 20 is drivenly connected to the inner wall of the conveyor belt 19. Both ends of the drive roller 18 and the driven roller 20 are rotatably connected to the interior of the conveyor frame 2. The conveyor belt 19 is used to carry and transport seeds, ensuring their stable flow.

[0043] Two toothed belts 21 are fixedly connected to the outer wall of the conveyor belt 19. The outer wall of the toothed belt 21 meshes with the outer wall of the gear 6. The toothed structure of the toothed belt 21 ensures the accuracy of transmission, avoids slippage, and improves the stability and transmission efficiency of the system. The auxiliary components include an electric telescopic rod 22 fixedly installed on the body of the sorting machine 1. A pusher 23 is fixedly connected to the telescopic end of the electric telescopic rod 22. The outer wall of the pusher 23 slides with the inner wall of the connecting pipe 11. The pusher 23 helps to push the seeds in the connecting pipe 11, ensuring that they can smoothly pass through the connecting pipe 11 and enter the barrier cylinder 9. The outer wall of the connecting pipe 11 slides with the inside of the barrier cylinder 9.

[0044] Working principle: During use, seeds enter through the feed inlet of the sorting machine body 1. After sorting, the seeds are discharged from the feed pipe 10 and then enter the barrier cylinder 9 through the connecting pipe 11. At this time, the drive motor 17 is started, and the output end rotates to drive the transmission roller 18 to drive the conveyor belt 19 to rotate the driven roller 20. This makes the conveyor belt 19 stably transport the seeds. At this time, the conveyor belt 19 drives the toothed belt 21 to move, causing the gear 6 meshing with it to rotate. This makes the seeds in the barrier cylinder 9 rotate. At this time, the seeds are discharged through the holes in the discharge cylinder 8 and dispersed on the conveyor belt 19, ensuring the stability and uniformity of the feeding during the seed transportation process.

[0045] Then, when it is necessary to flexibly adapt to the sorting requirements of different seed sizes, the push button inside the sleeve 2 5 can be pushed to move the chuck 2 15, separating the chuck 2 15 from the chuck 1 7. At this time, the movement of the chuck 2 15 simultaneously pushes the blocking cylinder 9 to move, causing the blocking cylinder 9 to deform the spring 13. Then, the operator can forcefully rotate the push-pull button 16 with their palm to make the blocking cylinder 9 rotate, simultaneously causing one end of the spring 13 to rotate as well. This allows the groove on the blocking cylinder 9 to contact the holes of other diameters on the discharge cylinder 8. Except for the groove, which will block the holes of other seeds, it can adapt to different seed sizes, ensuring accurate screening and sorting of different seeds. At the same time, when the speed needs to be adjusted or blockage is encountered during the discharge conveying process, the electric telescopic rod 22 can be activated, causing its telescopic end to drive the push cylinder 23 to move, pushing the seeds into the blocking cylinder 9 to help with feeding.

[0046] 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.
