Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional culture racks, in particular to a three-dimensional culture rack structure. Background Art

[0002] The stem of tomato is a kind of herbaceous semi-erect creeping stem, and cultivation measures such as trellis, vine hanging, and vine dropping are required during cultivation. In production, it is usually planted in a single layer in greenhouses and plastic greenhouses. When the ground layer of crops grows, the tall space on the upper part is idle and wasted. Domestic large-scale multi-span greenhouse tomatoes mostly adopt single-layer long-season cultivation. The vegetable growth period is long, the root system is aged, the resistance is reduced, and the disease is aggravated, which ultimately leads to reduced yield and efficiency. Long-season tomato cultivation also has the problem of time-consuming and labor-intensive vine dropping. In terms of cultivation methods, domestic greenhouses mostly use soil cultivation. Traditional soil cultivation has a large amount of irrigation and fertilizer application, and there are problems of large-scale use of nitrogen and nutritional imbalance, which leads to serious continuous cropping obstacles, low yields, and serious diseases. When using substrate soilless cultivation, there is a high one-time investment cost, and the substrate disinfection is labor-intensive and time-consuming when changing crops, and there is also the problem of substrate scrapping in the end. Effective solutions are urgently needed to address the problems of efficient use of space in greenhouses and plastic sheds, soil continuous cropping obstacles, nutritional imbalance and vine fall problems in traditional long-season tomato cultivation, and high input and low output in substrate soilless cultivation.

[0003] The utility model with authorization announcement number CN215935839U discloses a double-layer three-dimensional soilless cultivation equipment for tomatoes, including a bracket, a cultivation trough and a cultivation barrel. The bracket is a double-layer frame structure composed of a vertical support frame and a horizontal support beam, which is narrow at the bottom and narrow at the top. A plurality of cylindrical cultivation troughs are evenly arranged on the horizontal support beam, and a cultivation barrel is movably arranged in the cultivation trough. A liquid storage cavity is formed between the cultivation trough and the cultivation barrel. A traction fixing frame is movably installed at the opening of the cultivation barrel, a liquid inlet is opened on the upper part of the side wall of the cultivation barrel, and a plurality of flat liquid ports are evenly opened on the circumference of the side wall of the cultivation barrel, and a liquid outlet is opened at the bottom of the cultivation trough. The liquid outlet of the cultivation trough is connected to the liquid inlet on the adjacent cultivation trough through an infusion pipe, and a micro-boosting pump is arranged on the infusion pipe. A total liquid inlet pipe is fixed on the vertical support frame on one side, and a total liquid outlet pipe is fixed on the vertical support frame on the other side. The total liquid inlet pipe is connected to the two liquid inlets through the infusion pipes of the upper and lower layers at the same time, and the total liquid outlet pipe is connected to the two liquid outlets through the infusion pipes of the upper and lower layers at the same time. A total liquid inlet pipe is provided with a total infusion pump, and a total liquid outlet pipe is provided with a total liquid return pump. The total liquid outlet pipe and the total liquid inlet pipe are connected to the nutrient solution storage box at the same time, and the nutrient solution storage box, the total liquid inlet pipe, multiple infusion pipes and the total liquid outlet pipe form a circulation loop of the nutrient solution.

The distances between the nodes are equal, which is convenient for limiting the process of raising or lowering the culture rack 7 to prevent damage to the seedlings due to the close distance between two adjacent culture racks 7.

[0035] The projection of each culture rack 7 is wavy, and grooves for placing soil are provided on the culture rack 7. Arranging the culture rack 7 in a wavy shape facilitates placing more soil in a limited space.

[0036] The culture rack 7 is provided with a plurality of seedling clips for assisting plant growth. During the growth of the tomato seedlings, the seedling clips are used to restrain the young stems of the tomato, which is beneficial to the growth of the tomato seedlings.

[0037] Embodiment 2

[0038] like Figure 1-3 As shown, the three-dimensional culture rack structure proposed by the present invention further discloses the specific structure of the retractable mechanism compared to the first embodiment.

[0039] The retracting and releasing mechanism comprises a first wire wheel 5, a connecting wire and a multi-groove wire wheel 8;

[0040] Eight first wire wheels 5 are rotatably connected to the first mounting plate 3, and the eight first wire wheels 5 are arranged side by side;

[0042] Eight wire grooves are provided on the multi-groove wire wheel 8, and connecting wires a are arranged in each of the eight wire grooves. The other ends of the eight connecting wires a pass through the eight first wire wheels 5 respectively and pass through multiple culture racks 7 in sequence along the height direction of the supporting plate 1; by arranging eight wire grooves on the multi-groove wire wheel 8 and corresponding the connecting wires a on the eight first wire wheels to the eight wire grooves on the multi-groove wire wheel 8 one by one, the motor 6 will not interfere with each other when driving the multi-groove wire wheel 8 to reel in the wire.

[0043] In summary, in the utility model, tomato seeds are first sown in the grooves of the culture rack 7, and then the multi-groove wire wheel 8 is driven to rotate by the motor 6, and the multi-groove wire wheel 8 reels in the connecting wire a. The connecting wire a shortens the distance between each culture rack 7 to a minimum with the assistance of the first wire wheel 5 and the nodes on the connecting wire a. At this time, the motor 6 is turned off, and the counterweight 12 counterweights the culture rack through the connecting wire b. At the same time, the counterweight 12 slides to the specified position on the connecting wire c through the rotation of the third wire wheel 10 and the fourth wire wheel 11.

[0044] As the tomato seedlings grow gradually, the motor 6 drives the multi-groove wire wheel 8 to rotate in the opposite direction, the first wire wheel 5 is released, the culture rack 7 is lowered to a suitable position, and the young stems of the seedlings are restrained by the seedling clamps to assist their growth. The counterweight 12 slides on the connecting line c according to the connection line a to assist the counterweight in maintaining balance.

[0045] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
