Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model. Embodiment

[0026] The preferred embodiment of the industrial hemp classification and seed selection device provided by the present utility model is as Figures 1 to 5 shown: An industrial hemp classification and seed selection device includes a processing box 1. At the top end of the inner wall of the processing box 1, a mounting frame 16 is fixedly connected. The processing box 1 has a fixing effect on the mounting frame 16. On the outside of the mounting frame 16, evenly distributed first spring pieces 17 are fixedly connected. The mounting frame 16 has a fixing effect on the first spring pieces 17. Inside the multiple first spring pieces 17, a same first sieve plate 18 is fixedly connected. On the outside of the first sieve plate 18, evenly distributed second spring pieces 19 are fixedly connected. The first sieve plate 18 has a fixing effect on the second spring pieces 19. Inside the multiple second spring pieces 19, a second sieve plate 20 is fixedly connected. On the right side of the top end of the second sieve plate 20, a mounting plate 21 is fixedly connected. The second sieve plate 20 has a fixing and supporting effect on the mounting plate 21. At the top end of the mounting plate 21, a double-headed motor 22 is fixedly connected to further improve the stability of the double-headed motor 22. Both driving ends of the double-headed motor 22 are fixedly connected with cranks 23. The double-headed motor 22 can drive the cranks 23 to rotate. On the outside of the cranks 23, connecting rods 24 are fixedly connected, and further drive the connecting rods 24 to rotate by a certain amplitude. At the left end of the inner walls of the two connecting rods 24, a same rotating shaft 25 is fixedly connected. The rotating shaft 25 is rotatably connected to the upper left side of the first sieve plate 18. By the rotation of the connecting rods 24, the first sieve plate 18 is driven to vibrate. Since the first sieve plate 18 is connected to the second sieve plate 20 through the second spring pieces 19, the second sieve plate 20 is further driven to vibrate by the vibration of the first sieve plate 18, thereby achieving the layered screening effect of the crushed food. On the right side of the second sieve plate 20, a discharge plate 26 is fixedly connected. The second sieve plate 20 has a fixing effect on the discharge plate 26. At the bottom end of the inner wall of the processing box 1, a first collection box 27 is placed. In the middle of the bottom end of the processing box 1, a second collection box 28 is fixedly connected. The processing box 1 has a fixing effect on the second collection box 28.

[0027] In this embodiment, the first collection box 27 is located at the lower right side of the discharge plate 26, and the second collection box 28 is located at the bottom end of the first sieve plate 18. After the initial screening by the second sieve plate 20, the larger particles enter the first collection box 27 through the discharge plate 26 for collection, while the smaller particles enter the second collection box 28 after being screened again by the first sieve plate 18 for collection. Thus, the size and shape of the seeds can be classified more precisely, which helps to separate the seeds and impurities that do not meet the standards, thereby improving the accuracy of seed selection. The bottom end of the processing box 1 is fixedly connected with uniformly distributed support legs 29. Embodiment

[0028] On the basis of Embodiment 1, a preferred embodiment of the classification and seed selection device for industrial hemp provided by the present utility model is as Figures 1 to 5 shown: A storage box 2 is fixedly connected to the left side of the top end of the processing box 1. The processing box 1 provides a fixed support effect for the storage box 2. A mounting seat 3 is fixedly connected to the right side of the storage box 2. The storage box 2 provides a fixed support effect for the mounting seat 3. A limiting frame 13 is fixedly connected to the lower right side of the bottom end of the mounting seat 3. The mounting seat 3 provides a fixed effect for the limiting frame 13. A discharge pipe 15 is fixedly connected to the middle of the bottom end of the mounting seat 3. The mounting seat 3 provides a fixed effect for the discharge pipe 15. The output port of the discharge pipe 15 is located at the top end of the inner wall of the processing box 1. Thus, the seeds discharged from the discharge pipe 15 can fall into the processing box 1.

[0029] In this embodiment, a guiding groove 4 is formed in the right end of the inner wall of the mounting seat 3. A driving motor 5 is fixedly connected to the top right side of the mounting seat 3 to further improve the stability of the driving motor 5. A support block 7 is fixedly connected to the bottom right side of the mounting seat 3. The mounting seat 3 provides a fixed effect for the support block 7.

[0030] In this embodiment, a screw rod 6 is fixedly connected to the driving end of the driving motor 5. The driving motor 5 can drive the screw rod 6 to rotate. The bottom end of the screw rod 6 is rotatably connected to the top end of the support block 7 to further improve the stability of the screw rod 6 during rotation. A threaded block 8 is threadedly connected to the outside of the screw rod 6.

[0031] In this embodiment, the threaded block 8 is slidably connected to the inside of the guiding groove 4. By rotating the screw rod 6, the threaded block 8 slides inside the guiding groove 4, and the guiding groove 4 limits it to prevent it from shifting. A first hinge frame 9 is fixedly connected to the right side of the threaded block 8. By moving the threaded block 8, the first hinge frame 9 is driven to move. A transmission rod 10 is rotatably connected to the inside of the first hinge frame 9.

[0032] In this embodiment, the other end of the transmission rod 10 is rotatably connected to the second hinge frame 11. During the movement of the first hinge frame 9, the second hinge frame 11 is driven through the transmission rod 10 to drive the movable plate 12 to move. The bottom end of the second hinge frame 11 is fixedly connected to the movable plate 12. The movable plate 12 is slidably connected to the inner wall of the limiting frame 13. The limiting frame 13 can position the moving direction of the movable plate 12, thereby further improving the stability of the movable plate 12 during movement.

[0033] In this embodiment, a baffle 14 is fixedly connected to the left side of the movable plate 12. The movement of the movable plate 12 drives the baffle 14 to move synchronously. The baffle 14 is slidably connected to the inner wall of the discharge pipe 15, and the discharge pipe 15 is blocked to different degrees by the baffle 14, achieving the effect of controlling the discharge flow rate of hemp seeds and ensuring that the flow rate of seeds in different stages matches the processing speed.

[0034] The working principle and usage process of the present utility model are as follows: First, place hemp in the storage bin 2, start the drive motor 5, drive the screw rod 6 to rotate through the drive motor 5, and then drive the threaded block 8 to slide inside the guide groove 4. The movement of the threaded block 8 drives the first hinge frame 9 to move, and the second hinge frame 11 is driven through the transmission rod 10 to drive the movable plate 12 to move. During the movement of the movable plate 12, the limiting frame 13 positions its moving direction, thereby further improving its stability. The movement of the movable plate 12 drives the baffle 14 to move, and the discharge pipe 15 is blocked to different degrees by the baffle 14, achieving the effect of controlling the discharge flow rate of hemp seeds and ensuring that the flow rate of seeds in different stages matches the processing speed. The hemp falls into the processing box 1 through the discharge pipe 15 and lands on the second sieve plate 20. Start the double-headed motor 22, drive the crank 23 to rotate through the double-headed motor 22, and further drive the connecting rod 24 to rotate by a certain amplitude. The rotation of the connecting rod 24 drives the first sieve plate 18 to vibrate. Since the first sieve plate 18 is connected to the second sieve plate 20 through the spring piece two 19, the vibration of the first sieve plate 18 further drives the second sieve plate 20 to vibrate, thereby achieving the effect of layered screening of the crushed food. After the initial screening by the second sieve plate 20, the larger particles enter the collection box one 27 through the discharge plate 26 for collection, while the smaller particles enter the collection box two 28 through the re-screening by the first sieve plate 18 for collection. Thus, the size and shape of the seeds can be classified more precisely, which helps to separate out non-standard seeds and impurities, thereby improving the accuracy of seed selection, accelerating the processing process, and improving the efficiency of the entire seed selection process.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
