Description

Technical Field

[0001] This utility model relates to the field of tissue culture seedling technology of Chinese medicinal materials, and in particular to a device for grading and screening tissue culture seedlings of Chinese medicinal materials and protecting their root system. Background Technology

[0002] Grading and screening of Chinese medicinal tissue culture seedlings refers to the process of classifying and selecting Chinese medicinal seedlings propagated through plant tissue culture technology (seedlings cultivated using plant cells or tissues in a sterile environment) according to specific growth indicators and quality standards.

[0003] The reliance on manual transplanting in the grading and screening process of tissue culture seedlings for medicinal herbs has significant drawbacks. During manual operation, operators must first assess and grade the seedlings based on indicators such as seedling height, stem diameter, number of leaves, and root development using visual observation and simple measuring tools (such as rulers and calipers). Then, they carefully remove the seedlings of different grades from the culture container by hand and transplant them into corresponding seedling trays or planting substrates. This process not only consumes a significant amount of time and manpower, but also suffers from a high root damage rate due to the limited precision of manual operation, making it difficult to ensure consistency in grading standards and standardized transplanting techniques. Furthermore, prolonged repetitive labor easily leads to operator fatigue, further reducing work efficiency. In addition, manual transplanting is slow, failing to meet the demands of large-scale rapid production of tissue culture seedlings, severely hindering the industrialization of tissue culture seedlings for traditional Chinese medicine. Therefore, we propose a grading and screening device for tissue culture seedlings of traditional Chinese medicine and a root protection device to address the aforementioned problems.

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.

[0018] The following is in conjunction with the appendix Figures 1-4 This utility model will be described in further detail.

[0019] In this embodiment, to address the significant drawbacks of relying on manual transplanting during the grading and screening of tissue culture seedlings for medicinal herbs, this invention discloses a device for grading and screening tissue culture seedlings and protecting their roots. Manual operation requires operators to first assess and grade the seedlings using visual observation and simple measuring tools (such as rulers and calipers) to determine indicators such as seedling height, stem diameter, number of leaves, and root development. Then, seedlings of different grades are carefully removed from the culture container by hand and transplanted into corresponding seedling trays or planting substrates. This process is not only time-consuming and labor-intensive, but also suffers from high root damage due to the limited precision of manual operation, making it difficult to ensure consistency in grading standards and standardized transplanting actions. Furthermore, prolonged repetitive labor easily leads to operator fatigue, further reducing work efficiency. In addition, manual transplanting is slow, failing to meet the demands of large-scale rapid production of tissue culture seedlings, severely hindering the industrialization of tissue culture seedlings for traditional Chinese medicine. The device includes a seedling tray 1, a movable frame 2 above the seedling tray 1, a first movable groove 3 and a second movable groove 4 inside the movable frame 2, a connecting frame 5 slidably arranged inside the second movable groove 4, a cylinder 6 fixedly arranged inside the connecting frame 5, a first drive rod 7 fixedly connected to the bottom output end of the cylinder 6, a lifting plate 8 fixedly arranged at the bottom of the first drive rod 7, an installation plate 9 detachably connected to the bottom of the lifting plate 8 by bolts, a connecting rod 10 fixedly arranged at the bottom of the installation plate 9, a lifting block 11 slidably arranged outside the connecting rod 10, a seedling picker 12 fixedly arranged at the bottom of the connecting rod 10, and a compaction plate 13 fixedly arranged behind the lifting block 11, the compaction plate 13 slidably arranged inside the seedling picker 12; Specifically, the cylinder 6 fixedly installed inside the connecting frame 5 can precisely control the up-and-down movement of the lifting plate 8 via the first drive rod 7 at the output end, thereby driving the mounting plate 9, connecting rod 10, seedling picker 12, and other components below to rise and fall synchronously. When it is necessary to operate on the tissue culture seedlings, the cylinder 6 pushes the first drive rod 7 down, so that the seedling picker 12 can accurately reach the location of the tissue culture seedlings; after the operation is completed, the cylinder 6 pulls the first drive rod 7 up, raising the seedling picker 12 and the tissue culture seedlings to a suitable height for subsequent movement and transplanting.

[0020] An electric push rod 14 is fixedly installed at the bottom front end of the lifting plate 8. A second drive rod 15 is fixedly connected to the bottom output end of the electric push rod 14. The bottom end of the second drive rod 15 is fixedly connected to the top of the lifting block 11. Specifically, an electric push rod 14 is fixedly installed at the bottom front end of the lifting plate 8, which controls the lifting block 11 to rise and fall through the second drive rod 15. During the seedling retrieval process, the electric push rod 14 first pushes the second drive rod 15 to raise the lifting block 11, which in turn raises the compaction plate 13, so that the seedling retriever 12 is in an open state, making it convenient to grab the tissue culture seedling; after the seedling retriever 12 grabs the tissue culture seedling, the electric push rod 14 pulls the second drive rod 15 to lower the lifting block 11, which in turn lowers the compaction plate 13. The compaction plate 13 slides inside the seedling retriever 12 and compacts the substrate around the roots of the tissue culture seedling, ensuring that the roots of the tissue culture seedling are not damaged while ensuring that the tissue culture seedling is firmly grasped.

[0021] A first screw 16 is rotatably disposed between the inner walls of the front and rear sides of the first movable groove 3. A first slider 17 is externally threaded to the first screw 16. A connecting frame 5 is fixedly disposed on the top of the first slider 17. Specifically, a first screw 16, rotatably mounted between the inner walls of the front and rear sides of the first movable groove 3, and a first slider 17 connected to the external thread constitute a screw drive mechanism. When the first screw 16 rotates, the first slider 17 slides within the first movable groove 3 along the axial direction of the first screw 16, thereby driving the connecting frame 5 fixed on the top of the first slider 17 to move horizontally, allowing the seedling taker 12 to be adjusted in position within the lateral range of the movable frame 2, thus enabling the operation of tissue culture seedlings in different positions.

[0022] A first motor 18 is fixedly installed on the front side of the movable frame 2, and the output end of the first motor 18 is fixedly connected to the front end of the first screw 16 through the movable frame 2. Specifically, a first motor 18 fixedly mounted on the front side of the movable frame 2 serves as a power source, driving the first screw 16 to rotate through its output end. The first motor 18 can precisely adjust its speed and direction according to control commands, thereby controlling the rotation speed and direction of the first screw 16, thus accurately controlling the moving speed and distance of the first slider 17 and the connecting frame 5, achieving precise positioning of the seedling picker 12 in the lateral direction.

[0023] A third movable groove 19 is provided on the front side of the seedling platform 1. A second screw 20 is rotatably arranged between the inner walls of the two sides of the third movable groove 19. A second slider 21 is externally threaded to the second screw 20. A movable frame 2 is fixedly arranged in front of the second slider 21. A second motor 22 is fixedly arranged on one side of the seedling platform 1. The output end of the second motor 22 is fixedly connected to one end of the second screw 20 through the seedling platform 1. Specifically, within the third movable groove 19 on the front side of the seedling tray 1, a screw drive mechanism consisting of a second screw 20 and a second slider 21 drives the movable frame 2, which is fixed to the front side of the second slider 21, to move back and forth. When the second screw 20 rotates, the second slider 21 slides along the second screw 20 within the third movable groove 19, allowing the entire movable frame 2 to move within the longitudinal range on the front side of the seedling tray 1, further expanding the operating range of the seedling taker 12.

[0024] The seedling tray 1 has a seedling trough 23 inside, and a high-definition camera 24 is fixedly installed on the rear side of the lifting plate 8. Specifically, the seedling tray 23 inside the seedling tray 1 is used to place tissue culture seedlings to be graded, screened, and transplanted. A high-definition camera 24 is fixedly installed on the rear side of the lifting plate 8, which can capture real-time image information of the tissue culture seedlings, including seedling height, stem diameter, number of leaves, and root development status. The captured image information can be transmitted to the control system, and the tissue culture seedlings can be automatically graded through image processing algorithms and preset grading standards, providing a basis for subsequent precise operations.

[0025] The specific working principle is as follows: First, the tissue culture seedlings to be graded and screened are placed in the seedling tray 23 of the seedling platform 1. The high-definition camera 24 captures images of the tissue culture seedlings, and the grading is completed after analysis by the control system. Then, the second motor 22 drives the second screw 20 to rotate, causing the moving frame 2 to move back and forth in front of the seedling platform 1, so that the seedling picker 12 reaches the longitudinal position of the target tissue culture seedling. At the same time, the first motor 18 drives the first screw 16 to rotate, causing the connecting frame 5 and the seedling picker 12 to move laterally within the moving frame 2, so as to achieve precise positioning of the seedling picker 12 on the plane. After positioning is completed, the cylinder 6 pushes the lifting plate 8 down through the first drive rod 7, so that the seedling picker 12 reaches the tissue culture seedling. Then, the electric push rod 14 raises the lifting block 11 through the second drive rod 15, opens the seedling picker 12 to grab the tissue culture seedling, and after grabbing, the electric push rod 14 pulls the second drive rod 15 to lower the lifting block 11, and the compaction plate 13 compacts the root substrate of the tissue culture seedling. Then, cylinder 6 pulls the first drive rod 7 upward, raising the tissue culture seedling to a certain height. The first motor 18 and the second motor 22 work together again to transfer the tissue culture seedling to the corresponding transplanting position. The electric push rod 14 causes the seedling taker 12 to open, completing the transplanting operation of the tissue culture seedling. This cycle is repeated to achieve automated grading and screening of Chinese medicinal herb tissue culture seedlings and root-protected transplanting, effectively solving the drawbacks of manual operation.
