[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6The utility model provides a technical solution: a lifting seedling cultivation rack, comprising a plurality of support frames 1 arranged up and down, the support frame 1 located at the top is slidably connected to the support frame 1 located at the bottom, a placing table 2 is slidably arranged in each support frame 1, and a height adjustment device 3 is arranged at both ends between two adjacent support frames 1, the height adjustment device 3 comprises four support rods 32, the four support rods 32 cooperate with each other and are respectively rotatably connected to the upper and lower support frames 1, a connecting block 33 is rotatably connected between the two supporting rods 32 that cooperate with each other, a transmission device that drives the connecting blocks 33 to approach each other is arranged between the two connecting blocks 33, and two guide rods 31 for guiding the sliding direction of the support frame 1 are also arranged at both ends between the two adjacent support frames 1, and the guide rods 31 are specifically a telescopic structure.

[0024] Specifically, the support frame 1 supports the placement platform 2, and the seedling culture dish is placed on the placement platform 2. The height adjustment device 3 is used to adjust the distance between adjacent support frames 1, so that during the growth of the seedlings, the distance between adjacent placement platforms 2 is adjusted to provide sufficient space for the growth of the seedlings. After the distance between the placement platforms 2 is adjusted, the distance between the upper and lower layers of seedlings can be adjusted to prevent the seedlings in the lower layer from blocking the light of the upper layer when the growth rate of the seedlings in the lower layer is too fast and greater than the growth rate of the seedlings in the upper layer. To adjust the distance of the support frame 1, the two connecting blocks 33 approach each other, driving the support rod 32 to rotate, and the support rod 32 supports the support frame 1 when rotating, thereby realizing the adjustment of the distance between adjacent support frames 1. When the distance between adjacent support frames 1 is adjusted, the guide rod 31 guides the sliding direction of the support frame 1 located above in the adjacent support frames 1, to prevent the support frame 1 from tilting when the distance is adjusted, thereby causing an unstable center of gravity.

[0025] The support frame 1 includes four support rods 11 distributed in a rectangular shape, a cross-shaped reinforcement rod 12 is fixedly connected between the two support rods 11 at the ends, the support rod 32 is rotatably connected to the cross-shaped reinforcement rod 12, the end of the guide rod 31 is fixedly connected to the cross-shaped reinforcement rod 12, and the placement table 2 is located between the four support rods 11.

[0026] Specifically, the support rod 11 matches the shape of the placement table 2 and is respectively located at the four corners of the placement table 2. The cross-shaped reinforcement rod 12 fixes the only two support rods 11 at the two ends of the four rectangularly distributed support rods 11 together. The support rod 32 rotates under the action of the connecting block 33 to support the cross-shaped reinforcement rod 12. By supporting the cross-shaped reinforcement rod 12, the height of the support rod 11 is driven to be adjusted, wherein the upper support rod 11 is inserted into the lower support rod 11 and is slidably connected thereto.

[0027] The transmission device includes a screw rod 34, and the circumferential sides of both ends of the screw rod 34 are respectively provided with positive threads and negative threads. The screw rod 34 passes through two guide rods 31 and two connecting blocks 33 at one time, and the screw rod 34 is threadedly connected to the two connecting blocks 33 through the positive threads and negative threads.

[0028] Specifically, the screw rod 34 is manually rotated, and under the action of the positive thread and the negative thread, the two connecting blocks 33 are driven to move closer to or farther from each other, and the guide rod 31 limits the position of the screw rod 34, so that the two connecting blocks 33 can be driven to move.

[0029] The guide rod 31 includes a first connecting rod 311 and a second connecting rod 312. A receiving groove 314 is provided at the end of the first connecting rod 311. The end of the second connecting rod 312 extends into the first connecting rod 311 through the receiving groove 314 and is slidably connected thereto. A ring block 341 is fixedly connected to the circumferential side of the end of the screw rod 34. A ring groove 315 matching the ring block 341 is provided in the first connecting rod 311. A strip groove 313 matching the screw rod 34 is provided in the second connecting rod 312.

[0030] Specifically, the first connecting rod 311 and the second connecting rod 312 can cooperate with the height adjustment of the support frame 1 to make corresponding length changes. The ring block 341 cooperates with the ring groove 315 to limit the position of the screw rod 34. The setting of the strip groove 313 will not interfere with the length change of the guide rod 31.

[0031] A first lifting rod 13 is fixedly connected between the two support rods 11 located on the side, a second lifting rod 14 is fixedly connected between the two first lifting rods 13, the placement table 2 is arranged above the first lifting rod 13 and the second lifting rod 14, a T-shaped block 24 is fixedly connected to the lower surface of the placement table 2, and a T-shaped groove 141 matching the T-shaped block 24 is opened on the upper surface of the second lifting rod 14.

[0032] Specifically, the first lifting rod 13 cooperates with the second lifting rod 14, and under the action of the cross-shaped reinforcement rod 12, the four support rods 11 are fixed together. The placement table 2 achieves stable sliding through the cooperation of the T-block 24 and the T-slot 141, so that the placement table 2 can slide out of the support frame 1, so that the seedlings can be fully exposed to light. Among them, the lower surface of the second lifting rod 14 is provided with a slide groove connected to the T-slot 141, and the lower surface of the second lifting rod 14 is provided with a knob 25. The end of the knob 25 extends into the T-slot 141 through the slide groove and is threadedly connected to the T-block 24 to fix the position of the placement table 2.

A limiting plate 22 is fixedly connected between the inner walls at the top of the slide plate 21 . A limiting cavity 23 is provided on the upper surface of the limiting plate 22 .

[0034] Specifically, the culture dish is placed in the limiting cavity 23 to limit the position of the culture dish.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] During operation, it is only necessary to slide the position of the placement table 2 so that the placement table 2 moves out of the support frame 1 so that the seedlings are fully exposed to light, and then manually rotate the screw rod 34, which drives the connecting blocks 33 to move closer to or away from each other, thereby achieving the height adjustment of the support frame 1.
