DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0024] Please refer to Figure 1 - Figure 2 , the present utility model provides the following technical solutions: A saffron seedling test cultivation device includes a frame 1. One end of the bottom of the frame 1 is fixedly installed with a motor 2. The output shaft of the motor 2 penetrates through the inside of one side support plate 6 and is fixedly sleeved with a ball screw 3. One end of the ball screw 3 extends into the inside of the other side support plate 6. A slider 4 is threadedly connected to the outer surface of the ball screw 3. The top of the slider 4 is fixedly connected with a connecting rod 5. The top of the connecting rod 5 penetrates through the middle partition of the frame 1 and is movably connected with a sliding rod 7. Both ends of the sliding rod 7 penetrate through the bottom end of the first linkage rod 8 and extend into the notch inside the linkage rod support 12. One side of the top of the first linkage rod 8 is movably connected with a shelf 9. Sliding grooves 10 are opened on both sides of the shelf 9. One side of the middle of the first linkage rod 8 is movably connected with a second linkage rod 11. The top of the second linkage rod 11 is slidably connected to the inner wall of the sliding groove 10. The bottom end of the second linkage rod 11 is movably connected to one end of the linkage rod support 12. A seedling cultivation plate 13 is snap-connected inside the shelf 9.

[0025] Specifically, when it is necessary to adjust the growth space of saffron seedlings, the staff starts the motor 2, and its output shaft drives the ball screw 3 to rotate. The ball screw 3 drives the slider 4 to perform a linear motion along the screw. During the movement of the slider 4, the sliding rod 7 is driven to perform a linear movement in the notch inside the linkage rod support 12 through the connecting rod 5. While the sliding rod 7 is moving, the first linkage rod 8 is driven to move, causing the first linkage rod 8 to change its angle. While the angle of the first linkage rod 8 is changing, the second linkage rod 11 on one side also moves accordingly. The top of the second linkage rod 11 slides in the sliding groove 10, and the bottom end moves at one end of the linkage rod support 12, thereby jointly driving the shelf 9 and the seedling cultivation plate 13 to move up and down, so as to realize the precise adjustment of the position of the shelf 9, which can provide the most suitable growth conditions for saffron seedlings, make full use of the space, can accommodate more seedling cultivation plates, and improve the scale and efficiency of test cultivation.

[0026] Please refer to Figure 3 - Figure 5 , a clamping block 19 is fixedly connected to one side of the seedling cultivation plate 13, and the seedling cultivation plate 13 is slidably connected to the inner wall of the shelf 9.

[0027] Specifically, in the initial state, the seedling-raising plate 13 is preliminarily fixed to the shelf 9 through the clamping block 19 on one side, ensuring that the seedling-raising plate 13 is stably located inside the shelf 9 and will not easily fall off or shift.

[0028] Please refer to Figure 3 - Figure 5 , a transmission groove 17 is provided on one side of the shelf 9, a gear 16 is positioned and installed on the inner wall of the transmission groove 17, and a rack 22 is meshed and installed on the outer surface of the gear 16.

[0029] Specifically, the gear 16 is positioned and installed on the inner wall of the transmission groove 17 so that it can rotate stably around the axis. When an external force acts on the gear 16, the gear 16 drives the rack 22 to move, thereby pushing other components to move.

[0030] Please refer to Figure 3 - Figure 5 , both ends of the rack 22 are movably connected with springs 21, and one end of the spring 21 is fixedly connected to the inner wall of the transmission groove 17.

[0031] Specifically, when the rack 22 is driven to move by an external force, the two springs 21 will be compressed and stretched respectively. When the external force disappears or decreases, the spring 21 will release the stored energy, pushing the rack 22 back to the initial position, helping the rack 22 to reset smoothly and contributing to the stability of the rack 22.

[0032] Please refer to Figure 3 - Figure 5 , a connecting block 20 is fixedly connected to one side of the rack 22, and a tongue 18 is fixedly connected to one end of the bottom of the connecting block 20. The tongue 18 is fitted into the notch at the top of the clamping block 19.

[0033] Specifically, when the tongue 18 is fitted into the notch at the top of the clamping block 19, it can restrict the movement of the clamping block 19 and the seedling-raising plate 13 connected thereto, achieving the functions of fixation and locking. When the rack 22 drives the connecting block 20 to move and the tongue 18 disengages from the notch at the top of the clamping block 19, the seedling-raising plate 13 can slide freely.

[0034] Please refer to Figure 3 - Figure 5 , a rotating shaft 15 is fixedly sleeved inside the gear 16, and one end of the rotating shaft 15 penetrates through the side wall of the shelf 9 and is fixedly connected to a cross handle 14.

[0035] Specifically, when the cross handle 14 is rotated, the rotating shaft 15 fixedly connected thereto will rotate accordingly. The rotation of the rotating shaft 15 will drive the gear 16 to rotate together, thereby triggering a series of subsequent actions to achieve the fixation or unlocking of the seedling-raising plate 13.

[0036] Please refer to Figure 1 - Figure 2 , the first linkage rod 8 and the second linkage rod 11 have the same size and are symmetrically arranged about the axis of the linkage rod support 12.

[0037] Specifically, the first linkage rod 8 and the second linkage rod 11, which are symmetrically arranged and have the same size, can make the force on the shelf 9 more uniform, improve the stability of the entire structure, reduce shaking and imbalance, and ensure compliance with the requirements of experimental cultivation.

[0038] The working principle and usage process of the present utility model: During the use of the present utility model, when it is necessary to adjust the growth space of saffron seedlings, the staff starts the motor 2, and its output shaft drives the ball screw 3 to rotate. The ball screw 3 drives the slider 4 to move linearly along the screw. During the movement of the slider 4, the connecting rod 5 drives the sliding rod 7 to move linearly in the inner slot of the linkage rod support 12. While the sliding rod 7 is moving, it drives the first linkage rod 8 to move, causing the first linkage rod 8 to change its angle. While the angle of the first linkage rod 8 is changing, the second linkage rod 11 on one side also moves accordingly. The top end of the second linkage rod 11 slides in the sliding groove 10, and the bottom end moves at one end of the linkage rod support 12, thereby jointly driving the shelf 9 and the seedling-growing plate 13 to move up and down, so as to achieve precise adjustment of the position of the shelf 9, provide the most suitable growth conditions for saffron seedlings, make full use of the space, be able to accommodate more seedling-growing plates, and improve the scale and efficiency of experimental cultivation. When it is necessary to replace the seedling-growing plate 13, rotate the cross handle 14, which drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the gear 16 to rotate. The rotation of the gear 16 drives the movement of the rack 22. When the rack 22 moves, it will compress or stretch the springs 21 movably connected to its two ends and drive the connecting block 20 to move, and further cause the tongue 18 at the bottom end of the connecting block 20 to move accordingly. When the tongue 18 disengages from the top slot of the block 19, the staff can pull out the seedling-growing plate 13 from the inner wall of the shelf 9 to achieve the purpose of replacing the seedling-growing plate 13. This design is convenient and fast to operate, can provide a stable fixing effect, and greatly improves the work efficiency when it is necessary to frequently replace or adjust the seedling-growing plate 13.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. 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.
