Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a multi-layer support for seedling propagation experiments. Background Technology

[0002] In the field of agricultural planting, it is necessary to conduct propagation experiments on planted seedlings. Therefore, multi-layered supports are needed to hold the planted seedlings.

[0003] A search revealed a Chinese patent publication number CN220693882U, which discloses a multi-layer support for seedling propagation experiments. The support includes a base plate with connecting columns. Multiple sets of mounting rails are mounted on the connecting columns, and multiple seedling trays are installed inside the mounting rails. The connecting columns also have positioning components for fixing the seedling trays. This patent allows the positioning components to fix the seedling trays at different heights within the mounting rails according to actual planting needs, and allows for staggered installation, ensuring that the seedlings in each tray receive sunlight evenly, thus improving the seedling propagation effect.

[0004] However, the positioning component requires pressing two pressing blocks simultaneously during operation. Since the pressing blocks are located at the center of one end of the seedling tray and the overall area of ​​the seedling tray is relatively large, the user will be disturbed by the seedling tray when pressing the pressing blocks with one hand, making the operation inconvenient. If both hands are used to press the blocks, the operation will also be inconvenient when moving the seedling tray. Utility Model Content

[0027] Example 1

[0028] A multi-layer scaffold for seedling propagation experiments, such as Figures 1 to 3As shown, the device includes a base plate 1. A support rod 2 is fixedly connected to the top outer wall of the base plate 1. Multiple parallel annular slide rails 3 are provided on the side wall of the support rod 2, and insertion slots communicating with the multiple annular slide rails 3 are provided on the side wall of the support rod 2. A connecting rod 5 is slidably fitted onto the inner wall of the annular slide rail 3. A seedling tray 4 is fixedly connected to one end of the connecting rod 5. Two opposing limiting blocks 6 are slidably fitted onto the inner wall of the connecting rod 5. The same limiting spring 7 is connected to the inner wall of the two limiting blocks 6. The annular slide rail 3 has... Multiple slots that cooperate with the limiting block 6 are arranged circumferentially around the axis of the support rod 2. A pressure plate 8 is fixedly connected to the side wall of the limiting block 6. A pressing block 9 is slidably fitted to the inner wall of the connecting rod 5. A V-groove is opened at one end of the pressing block 9. An inclined surface that slidably fits the inner wall of the V-groove is provided near the end of the two pressure plates 8 near the pressing block 9. A tension spring 10 is connected to one end of the pressing block 9. The other end of the tension spring 10 is connected to the inner wall of the connecting rod 5. A push block 11 is fixedly connected to the side wall of the pressing block 9.

[0029] The top outer wall of the support rod 2 is rotatably fitted with a rotating platform. A water storage tank 15 is fixedly connected to the top of the rotating platform. A motor that drives the rotating platform is installed inside the support rod 2. A sprinkler pipe 14 located below the water storage tank 15 is fixed to the inner wall of the rotating platform. The sprinkler pipe 14 is connected to the water storage tank 15, and a water leakage hole is opened on the bottom side wall of the sprinkler pipe 14. A support ring 16 is fixed to the inner wall of the water storage tank 15. A fixing ring 17 is supported on the top outer wall of the support ring 16. A filter plate 18 is fixed to the inner wall of the fixing ring 17. A lifting rod is fixed to the top outer wall of the filter plate 18. A collection box 19 is fixed to the top outer wall of the base plate 1. The top outer wall of the collection box 19 is set as an inclined surface that is inclined towards the axis of the support rod 2. A water inlet slit is opened on the top of the collection box 19. A drain outlet is provided on the side wall of the collection box 19.

[0030] The seedling tray 4 is moved, and the push block 11 is pushed towards the support rod 2, which drives the connecting rod 5 to move. The tension spring 10 is stretched and deformed. The V-shaped groove squeezes the inclined surface of one end of the pressure plate 8, causing the two pressure plates 8 to move relative to each other. This causes the limiting block 6 to move relative to each other. The limiting spring 7 is compressed and deformed, causing the limiting block 6 to disengage from the slot. The connecting rod 5 can move along the annular slide rail 3 to change the position of the seedling tray 4. When watering, water is injected into the water storage cylinder 15. After being filtered by the filter plate 18, the water flows into the sprinkler pipe 14 and leaks out from the drain hole, falling onto the seedling tray 4. At the same time, the motor drives the rotating table to rotate, so that multiple seedling trays 4 can be watered. The water falling from the gap between multiple seedling trays 4 falls onto the top of the collection box 19 and flows to the water inlet after being guided by the inclined surface. Then it enters the collection box 19 and collects. When cleaning the filter plate 18, it can be removed from the water storage cylinder 15 by lifting the rod.

[0031] With the pressure plate 8, the squeezing block 9, the tension spring 10 and the push block 11 provided, when the user moves the seedling tray 4, the two limit blocks 6 can be moved synchronously by pushing the push block 11 with one hand, thus releasing the seedling tray 4 from the fixation, making the operation convenient.

[0032] By setting up a collection box 19, water spilled during watering can be collected and utilized, saving water resources and improving the utilization rate of water resources.

[0033] Example 2

[0034] A multi-layer support for seedling propagation experiments. This embodiment is based on Embodiment 1 and makes the following improvements, such as... Figures 3 to 4 As shown, the outer wall of the seedling tray 4 has multiple planting cavities, and the inner wall of the planting cavity is slidably fitted with a push plate 12. The bottom ends of the multiple push plates 12 located on the same seedling tray 4 are connected to the same linkage rod 13, and the linkage rod 13 is vertically slidably fitted with the seedling tray 4.

[0035] When removing the seedlings from the planting cavity, push the linkage rod 13 upward to move the push plate 12 upward along the planting cavity, pushing the seedlings and soil out of the planting cavity together.

[0036] With the push plate 12 and linkage rod 13, the seedlings and soil in the planting cavity can be pushed out of the planting cavity together when the seedlings are taken out, thus avoiding damage to the root system of the seedlings when they are taken out.

[0037] Working principle: Moving the seedling tray 4 pushes the push block 11 towards the support rod 2, causing the connecting rod 5 to move. The tension spring 10 stretches and deforms, and the V-groove squeezes the inclined surface of one end of the pressure plate 8, causing the two pressure plates 8 to move relative to each other. This causes the limiting block 6 to move relative to each other, and the limiting spring 7 compresses and deforms, causing the limiting block 6 to disengage from the slot. The connecting rod 5 can then move along the annular slide rail 3, changing the position of the seedling tray 4. During irrigation, water is injected into the water storage cylinder 15. After being filtered by the filter plate 18, the water flows into the sprinkler pipe 14 and leaks out through the drain hole. Water falls onto the seedling tray 4, and at the same time, the motor drives the rotating table to rotate, so that multiple seedling trays 4 can be watered. Water falling from the gaps between multiple seedling trays 4 falls onto the top of the collection box 19, and flows to the water inlet after being guided by the inclined surface, and then enters the collection box 19 to collect. When cleaning the filter plate 18, it can be taken out of the water storage cylinder 15 by lifting the rod. When taking out the seedlings in the planting cavity, push the linkage rod 13 upward to make the push plate 12 move upward along the planting cavity, and push the seedlings and soil in the planting cavity out of the planting cavity together.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
