Description

Technical Field

[0001] The utility model relates to the technical field of soilless cultivation, in particular to a soilless cultivation planting frame with adjustable layer height. Background Art

[0002] Soilless cultivation planting racks are a type of planting equipment that does not use traditional soil but supports plant growth through nutrient solution, matrix or other media. It can be carried out in vertical spaces, roofs, balconies and other places without occupying a large amount of land resources. Soilless cultivation planting racks are an efficient, environmentally friendly and convenient planting method with broad application prospects and market potential.

[0003] The invention patent with the authorization announcement number CN111699869A discloses a planting rack for agricultural planting, which includes a cultivation trough, a support frame, and a crossbeam. The crossbeam is welded to the support frame, and the cultivation trough is embedded and connected to the support frame; the cultivation trough includes an upper connecting block, a fixed frame, a clamping frame, a connecting rod, a limiting rod, a lower connecting block, and an outer frame. The upper connecting block is clearance-matched with the fixed frame, the fixed frame is connected to the outer frame, the clamping frame is movably engaged with the connecting rod, the connecting rod is hinged to the fixed frame, the limiting rod is embedded and connected to the fixed frame, and the lower connecting block and the outer frame are an integrated structure. When the water spinach is pulled out, when the water spinach is pulled upward, the connecting rod can be swung upward along the fixed frame, so that the connecting rod can drive the clamping frame to loosen the soil inside the cultivation trough, so that the water spinach on the cultivation trough can be completely pulled out.

[0004] Although the planting rack for agricultural planting is convenient for pulling out vegetables, the device has the following problems in actual use: the multiple cultivation troughs provided by the device are fixedly installed on the support frame, and the cultivation troughs are fixedly connected to the support frame, so the heights of the multiple cultivation troughs are fixed. However, this fixed connection design also brings certain limitations: the height of the cultivation trough is fixed and cannot be flexibly adjusted according to the actual application scenario or changes in the natural environment, such as changes in light intensity and direction. When planting vegetables, flowers and other plants, light is one of the key factors affecting their growth. If the height of the planting rack cannot be adjusted in time according to the light conditions, some plants may grow slowly, have yellowing leaves, and have poor fruit quality due to being in an environment with insufficient light for a long time. This not only affects the ornamental value of the crop, but may also seriously affect the yield and quality of the crop. In view of this, we propose a soilless cultivation rack with adjustable layer height. Utility Model Content

[0033] In this embodiment, the cylinder 31 and the through hole 32 are located on the same vertical plane, and the cross-section of the cylinder 31 is annular. This design is conducive to cultivating crops in the opening of the through hole 32 and the cylinder 31.

[0034] In this embodiment, a fixing groove 211 is provided at the top of the bracket 21, and a fixing bolt 212 is threadedly connected to one side of the bracket 21; fixing plates 33 are fixed at both ends of the bottom of the culture tank 3, and the fixing plates 33 are plugged into the fixing groove 211. A connecting hole 331 is provided on the fixing plate 33, and the fixing bolt 212 passes through the connecting hole 331. Through plug-in fitting and bolt fixing, the stability of the culture tank 3 on the bracket 21 can be ensured, and it is easy to install and disassemble, which improves the maintainability and flexibility of the equipment.

[0035] In this embodiment, the cross-section of the bracket 21 is L-shaped, and the bracket 21 is fixedly connected to the sleeve 20 by bolts. The L-shaped cross-section provides good support strength and stability, and is suitable as a load-bearing structure. The bolt connection with the sleeve 20 makes the connection firm and stable.

[0036] In this embodiment, the cross-section of the connecting frame 22 is in the shape of a square, and the connecting frame 22 is tightly welded to the sliding sleeve 20. The square cross-section provides greater strength and rigidity, ensuring the structural strength of the connecting frame 22, and the tight welding ensures the firmness of the connection, reducing the potential safety hazards caused by looseness or vibration.

[0037] In this embodiment, a connecting plate 26 is fixed between the bottom ends of the two fixing rods 24, and a pull ring 27 is fixed to the bottom of the connecting plate 26. The pull ring 27 provides a convenient lifting point, making the operation more labor-saving.

The U-shaped cross-section provides a good sliding track, so that the diagonal brace 2 can move smoothly in the sliding sleeve 20, while ensuring the stability of the movement.

[0039] In this embodiment, the cross-section of the fixing frame 1 is in the shape of a square, and the fixing frame 1 is made of galvanized steel. The square cross-section provides a solid support structure that can withstand heavy weight and pressure. The galvanized steel material has good corrosion resistance and durability, can resist erosion from the external environment, and prolong the service life of the equipment.

[0040] It should be added that in this embodiment, a reinforcing block 28 is tightly welded at the connection between the connecting frame 22 and the sliding sleeve 20, and the overall shape of the reinforcing block is triangular. The setting of the reinforcing block increases the connection reliability between the connecting frame 22 and the sliding sleeve 20, and improves the connection stability between the connecting frame 22 and the sliding sleeve 20.

[0041] When adjusting the height of the culture tank 3, the user first pulls the pull ring 27 downwards, and the pull ring 27 drives the connecting plate 26 and the fixing rod 24 to move downwards, and the fixing rod 24 drives the slide plate 23 to move downwards, and the slide plate 23 compresses the spring 25. At this time, the top of the top of the fixing rod 24 disengages from the fixing hole 29, and the user pushes the sliding sleeve 20 to slide upward along the diagonal support 2. When the sliding sleeve 20 moves to a suitable height, the user releases the pull ring 27. Under the elastic action of the spring 25, the top of the fixing rod 24 is inserted into the fixing hole 29, and the sliding sleeve 20 is fixed to the diagonal support 2. Repeat the above steps and adjust the sliding sleeve 20 on the other diagonal support 2 to the same height. Next, the user aligns the fixing plate 33 at the bottom of the culture tank 3 with the fixing grooves 211 on both sides and inserts it, and tightens the fixing bolts 212. The fixing plate 33 is fixed to the fixing grooves 211, and the culture tank 3 completes the height adjustment and installation.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
