Description

Technical Field

[0001] The utility model belongs to the technical field of seedling cultivation, and specifically refers to a multi-layer seedling cultivation device. Background Art

[0002] Traditional multi-layer seedling cultivation racks can, within a limited space, increase the number of seedlings cultivated per unit area by vertically placing multiple seedling trays, effectively improving the seedling cultivation efficiency. Generally, in order to accurately control the seedling cultivation situation, the water supply, oxygen supply, temperature, humidity, and light in the seedling cultivation rack are uniformly managed to improve the success rate of seedling cultivation. Currently, there are the following several ways to supply water for seedling cultivation:

[0003] Tidal hydroponic water supply method: Simulating the tidal phenomenon, allowing the plant roots to soak in water for a period of time and then be exposed to the air, thereby promoting plant growth;

[0004] Drip irrigation water supply method: Directly delivering water and fertilizer to the plant roots through drip heads, reducing the waste of water and fertilizer;

[0005] Spray water supply method: The spray water supply method evenly sprays water and fertilizer on the seedling cultivation substrate through a spray head, ensuring that each plant can receive water and fertilizer evenly.

[0006] However, the above water supply methods all rely on a mature and stable water supply system and water supply pipelines, and during the hydroponic process, it is necessary to ensure that multi-layer seedling cultivation racks in the same environment are suitable for seedling-growing vegetation with the same type of requirements, which will result in the following negative situations:

[0007] When the number of seedlings is small, it will inevitably cause waste in the maintenance cost of the overall system;

[0008] In order to reduce the losses caused by the operation and maintenance costs of the seedling cultivation rack, multiple hydroponic plants are arranged on the same seedling cultivation rack. However, due to the differences in hydroponic species, the water requirements of different species are not the same. Too little water supply is likely to lead to poor growth of the seedlings, while too much water supply will cause rot in the branches above the plant roots. Summary of the Utility Model

A support spring is fixedly arranged between the end plate and the pushing circular plate. In the present utility model, the pushing circular plate slides in the connecting cavity pipe. Supported by the support spring, the pushing circular plate fits against the top of the transition cavity pipe. When the end of the inserting end head presses against the pushing circular plate and slides it in the connecting cavity pipe until the pushing circular plate slides into the funnel-shaped cavity pipe, the liquid supply in the retaining water tank enters the end pipe fitting through the end head holes and flows into the placement and culture plate member through the inserting horizontal pipe, realizing the connection between the liquid supply connection member and the placement and culture plate member and ensuring the smoothness of the liquid supply path.

[0017] Furthermore, the liquid supply connection member includes a retaining water tank, a connecting hose, an upper connecting pipe, a bottom cover, and a wrapping box body.

[0018] Preferably, the interpenetrating culture plate member includes a push-pull support pipe member and a placement culture plate member. The push-pull support pipe member includes an interpenetrating horizontal pipe and an interpenetrating end head. The interpenetrating end head is fixedly connected to one end of the interpenetrating horizontal pipe. The interpenetrating horizontal pipe is a hollow structure. The interpenetrating end head includes an end head pipe member and a rhombic ring. The interpenetrating end head is a hollow structure. The rhombic ring is fixedly connected to the outside of the end head pipe member. The end of the end head pipe member is provided with end openings in an array.

The liquid supply enters the placement plate from the self-fixing water tank through the interpenetrating horizontal pipe. As the liquid supply flows in, the floating plate rises with the liquid level of the liquid supply. When the floating plate rises to block the liquid supply inflow path of the placement plate, the further inflow of the liquid supply stops. When the cultivated plants require a large amount of water, as the liquid supply decreases, the floating plate drops with the liquid level, and the liquid supply inflow path of the placement plate is opened again, ensuring the autonomous adjustment of the liquid supply inflow amount according to the actual needs of the plants.

[0019] As a further preference of the present utility model, the plate member placement cavity is fixedly connected to the side surface of the wrapping box body. The plate member placement cavity includes a placement cavity wrapping shell and an opposing card slot. The opposing card slot is fixedly connected to the inner wall of the placement cavity wrapping shell. The interpenetrating horizontal pipe is inserted into the opposing card slot.

The interpenetrating end head can be pushed horizontally into the interpenetrating locking member, which is also convenient for controlling the environment inside the placement cavity wrapping shell later. Since the temperature control, humidity control, and light control devices are all existing mature devices, they will not be elaborated here.

[0020] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0021] (1) In the present utility model, the inclined surface of the upper sliding block is at the same inclination angle as the downward inclined surface of the rhombic ring. The inclined surface at the bottom of the guiding piece is at the same inclination angle as the upper inclined surface of the rhombic ring. The inclined surface of the lower sliding block is at the same inclination angle as the upper inclined surface of the rhombic ring. Through the mutual cooperation of each inclined surface, the insertion movement of the rhombic ring is assisted, which is convenient for the upper clamping member and the lower clamping member to position and lock the rhombic ring, and is also convenient for the removal of the rhombic ring, facilitating the operation of the operator.

[0022] (2) In the present utility model, the pushing circular plate is made to slide within the connecting cavity tube. Supported by the supporting spring, the pushing circular plate fits against the top of the transition cavity tube. When the end of the inserting end presses against the pushing circular plate and makes it slide within the connecting cavity tube until the pushing circular plate slides into the funnel-shaped cavity tube, the liquid supply in the liquid retaining water tank enters the end pipe fitting through the openings of the end holes, and flows into the placement culture plate through the inserting horizontal pipe, realizing the connection between the liquid supply connecting component and the placement culture plate, and ensuring the smoothness of the liquid supply path.

[0023] (3) In the present utility model, the floating plate is placed within the placement plate. The liquid supply enters the placement plate from the liquid retaining water tank through the inserting horizontal pipe. As the liquid supply flows in, the floating plate rises with the liquid level of the liquid supply. When the floating plate rises to block the liquid supply inflow path of the placement plate, the further inflow of the liquid supply stops. When the plants being cultivated require a large amount of water, as the liquid supply decreases, the floating plate drops with the liquid level, and the liquid supply inflow path of the placement plate is opened again, ensuring the autonomous adjustment of the liquid supply inflow volume according to the actual needs of the plants.

[0024] (4) In the present utility model, the placement cavity wrapping shell provides support for the opposing card slots, thus fixing the inserted culture plate while ensuring that the inserted culture plate is arranged in a horizontal state as a whole. The inserting end can be pushed horizontally into the inserting locking part, and it is also convenient for controlling the environment within the placement cavity wrapping shell in the later stage. Since the temperature control, humidity control, and light control devices are all existing mature devices, they will not be elaborated here. Brief Description of the Drawings

When the inserting end 58 is not inserted into the inserting locking member 4, the pushing circular plate 44 in the connecting pipe fitting 42 is supported by the support spring 50. The pushing circular plate 44 blocks the port of the transition cavity pipe 45 to prevent the liquid supply in the retention water tank 52 from flowing out. The vertical spring 14 supports the upper clamping member 12 and the lower clamping member 13 to be normally separated, and the top block 17 is located at the top of the vertical limiting groove 19 of the vertical block 16.

[0057] The operator pushes the inserted cultivation plate member 2, and the push-pull support pipe fitting 7 moves along the opposing clamping groove 10 towards the inserting locking member 4 until the inserting end 58 is inserted into the inserting locking member 4. The end pipe fitting 59 contacts the pushing circular plate 44 through the connecting pipe orifice 41. As the operator pushes, the end pipe fitting 59 pushes the pushing circular plate 44. The pushing circular plate 44 slides along the sliding support column 48, compressing the support spring 50. The rhombic ring 60 fixedly connected to the outside of the end pipe fitting 59 contacts the lower clamping member 13 of the inserting locking member 4. As shown in Figure 11 As shown, the two inclined surfaces of the rhombic ring 60 are the A surface and the B surface respectively. The A surface of the rhombic ring 60 contacts the bottom inclined surface of the lower sliding block 34. During the pushing process of the A surface of the rhombic ring 60, under the mutual restraint of the bottom clamping convex block 36 and the lower limiting groove 21 of the bottom block 18, the two side lower sliding blocks 34 squeeze the sliding insert 35 and move towards the vertical block 16 until the maximum diameter of the rhombic ring 60 slides over the top surface of the lower sliding block 34. Under the reset property of the sliding insert 35, the lower sliding block 34 resets and clamps the bottom of the rhombic ring 60 to fix the inserting end 58. At this time, the contact state between the rhombic ring 60 and the inserting locking member 4 is as shown inFigure 6 As shown, the liquid supply in the retention water tank 52 enters the inserted horizontal pipe 57 through the end opening 61 of the end pipe fitting 59. The liquid supply then enters the mounting plate 62 through the connection between the inserted horizontal pipe 57 and the mounting plate 62. The floating plate 63 rises as the liquid level of the inflowing liquid supply rises. When the floating plate 63 floats up to block the liquid inlet path of the mounting plate 62, no more liquid supply enters the mounting plate 62. When the hydroponic plants absorb water and the liquid level drops, the floating plate 63 drops with the drop of the liquid level. When the floating plate 63 stops blocking the liquid inlet path of the mounting plate 62, the liquid supply enters the mounting plate 62 again, and the floating plate 63 rises again as the liquid level of the liquid supply rises, realizing the dynamic balance of the liquid supply.

[0058] When it is necessary to remove the inserted culture plate member 2, the operator pushes the inserted culture plate member 2, and the push-pull support pipe fitting 7 further pushes the upper engagement member 12 forward. Under the push of the A surface of the rhombic ring 60, the inclined surface at the bottom of the guide piece 24 fits the A surface of the rhombic ring 60, and the guide piece 24 drives the two upper sliding blocks 23 to slide to both sides. The engaging convex block 27 at the top of the transverse plate 22 slides in the upper limiting groove 20 of the top block 17. The preliminary insertion member 25 and the backup insertion member 26 are squeezed until the B surface of the rhombic ring 60 contacts and fits the inclined surface of the upper sliding block 23. The top of the end pipe fitting 59 further pushes the push plate 44. Under the reset action of the preliminary insertion member 25, after the two upper sliding blocks 23 squeeze and fix the rhombic ring 60 on both sides, the operator pulls the inserted culture plate member 2 backward. During the backward movement of the rhombic ring 60, the upper engagement member 12 moves synchronously with the B surface of the rhombic ring 60 towards the lower engagement member 13. During this process, the vertical spring 14 is squeezed, and the guide piece 24 moves to the inner wall of the lower sliding block 34. During this process, the top block 17 slides in the vertical limiting groove 19 of the vertical block 16 along the sliding support groove 32 of the backup insertion member 26. As the rhombic ring 60 is pulled out, under the push of the B surface of the rhombic ring 60 on the inclined surface of the upper sliding block 23, while the two upper sliding blocks 23 move to both sides, the guide piece 24 synchronously pushes the lower sliding block 34, and the preliminary insertion member 25 and the sliding insertion member 35 are squeezed simultaneously. The end pipe fitting 59 no longer squeezes the push plate 44, and the support spring 50 resets, and the push plate 44 blocks the transition cavity pipe 45 to prevent the liquid supply in the retention water tank 52 from flowing out. Under the reset conditions of the vertical spring 14, the preliminary insertion member 25, the backup insertion member 26, and the sliding insertion member 35, both the upper engagement member 12 and the lower engagement member 13 are reset.
