Description

Technical Field

[0001] The utility model relates to the technical field of soilless cultivation greenhouses, and specifically to a multi-layered three-dimensional soilless cultivation greenhouse. Background Technique

[0002] Blueberries and blackberries have increasingly become popular fruits in the market due to their rich nutritional value and antioxidant properties. They not only contain a large amount of vitamins and minerals but also have the effect of promoting cardiovascular health. However, traditional soil cultivation methods have relatively high requirements for the natural environment, including suitable climate, high-quality soil, and sufficient land resources. The uncertainty of these conditions leads to problems such as yield fluctuations and uneven quality during the planting process, and also increases the risk of pests and diseases.

[0003] To overcome these limitations, soilless cultivation techniques have gradually been introduced into the planting of blueberries and blackberries. Soilless cultivation provides a stable and controllable growth environment for plants by using inert substrates and formulated nutrient solutions. Compared with traditional soil cultivation, soilless cultivation can effectively improve the utilization efficiency of water and fertilizers, reduce the occurrence of pests and diseases, and achieve continuous production throughout the year, greatly enhancing the stability of yield and product quality.

[0004] With the development of soilless cultivation techniques, planting greenhouses have been widely used. These greenhouses provide an ideal growth environment for crops by adjusting the internal temperature, humidity, and light conditions. However, there are some technical defects in the current greenhouse designs: the soilless planting racks are usually fixed to the ground, resulting in the following problems:

[0005] 1. Large space occupation: The planting racks are fixed to the ground, occupying a large amount of ground space and restricting the efficient use of space.

[0006] 2. Inconvenient cleaning: The planting racks are in more contact with the ground. Especially the soilless cultivation containers at the bottom are close to the ground, increasing the difficulty of cleaning the ground hygiene.

[0007] Therefore, there is an urgent need for an innovative cultivation device that can solve the limitations of the existing technology, improve space utilization rate and facilitate cleaning, and achieve more efficient production of blueberries and blackberries. In view of this, we propose a multi-layered three-dimensional soilless cultivation greenhouse. Content of the Utility Model

[0008] The purpose of the utility model is to provide a multi-layered three-dimensional soilless cultivation greenhouse to solve the problems raised in the above background technique.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] A multi-layer three-dimensional soilless cultivation greenhouse, including a plurality of brackets arranged at equal intervals left and right, as the main support structure of the greenhouse, providing overall stability and support force. A tarpaulin is covered on the outside of the plurality of brackets, covering the outside of the brackets, providing windproof, rainproof and heat insulation protection for the greenhouse. The inside of the soilless cultivation greenhouse includes a temperature and humidity control system, which is prior art and will not be elaborated here. The bracket includes two support columns arranged symmetrically front and back, vertically supporting the greenhouse structure, connecting the ground and the top, providing firm vertical support for the greenhouse. The tops of the two support columns arranged opposite to each other front and back are jointly connected with an arc-shaped top plate, forming an arched structure, supporting the tarpaulin, which helps rainwater flow and snow slide. A fixed longitudinal plate is provided between the two support columns arranged opposite to each other front and back and near the top;

[0011] A plurality of fixed cross beams arranged at equal intervals front and back are provided between two adjacent fixed longitudinal plates on the left and right, providing structural support for hanging a multi-layer three-dimensional soilless cultivation rack. A detachable multi-layer three-dimensional soilless cultivation rack is provided on each fixed cross beam, providing a multi-level planting space. The multi-layer three-dimensional soilless cultivation rack is in a suspended state, effectively avoiding occupying the ground space, improving the space utilization efficiency, and at the same time facilitating the staff to clean the ground. The multi-layer three-dimensional soilless cultivation rack includes two rectangular vertical rods arranged symmetrically left and right. A U-shaped hanging plate is provided at the top of the rectangular vertical rod. The U-shaped hanging plate is suspended outside the fixed cross beam, hanging on the fixed cross beam, used to fix and stabilize the cultivation rack, facilitating installation and disassembly. A plurality of fixed cross plates arranged at equal intervals up and down are provided between the two rectangular vertical rods, horizontally connecting the rectangular vertical rods, providing lateral support, and supporting the strip-shaped longitudinal rods. A plurality of strip-shaped longitudinal rods arranged at equal intervals left and right are provided on the front and back sides of the fixed cross plate, arranged on the fixed cross plate, supporting the circular cross tube, forming the framework of the planting pipeline. A plurality of strip-shaped longitudinal rods on the same side jointly support a circular cross tube. An inlet pipe is provided at the left end of the circular cross tube, and an outlet pipe is provided at the right end of the circular cross tube. A plurality of planting ports arranged at equal intervals left and right are opened at the top of the circular cross tube. The circular cross tube serves as a planting pipeline, with planting ports provided for planting blueberries and blackberries. The inlet pipe conveys nutrient solution to the circular cross tube to support plant growth. The outlet pipe discharges the excess nutrient solution from the circular cross tube to prevent waterlogging and excessive nutrient solution.

[0012] Preferably, two connecting side plates arranged symmetrically up and down are provided between two adjacent support columns on the left and right. The end of the connecting side plate is detachably connected to the side of the support column by bolts, connecting the support columns and increasing the lateral stability of the overall structure.

The top end of the reinforcing vertical rod is fixedly connected to the middle of the concave surface of the arc-shaped top plate, connecting the fixed vertical plate and the arc-shaped top plate, providing additional support and reinforcement, and increasing the strength of the top structure.

[0015] Preferably, rectangular positioning blocks are provided at the top of the fixed cross beam and near the left and right ends. Rectangular positioning holes are opened at the top of the inner wall of the U-shaped hanging plate. The rectangular positioning blocks are located in the rectangular positioning holes. The rectangular positioning holes cooperate with the rectangular positioning blocks to ensure the stable positioning of the U-shaped hanging plate. The distance a between the upper and lower sides of the inner wall of the U-shaped hanging plate and the total thickness b of the rectangular positioning block and the fixed cross beam have a relationship that a is greater than b, ensuring that the U-shaped hanging plate can move upward and then move forward to remove the positioning of the U-shaped hanging plate, facilitating the installation and disassembly of the multi-layer three-dimensional soilless cultivation rack by the staff.

[0016] Preferably, the opening of the U-shaped hanging plate faces backward. A rectangular anti-slip block is provided at the top of the rear side of the U-shaped hanging plate. The front side of the rectangular anti-slip block is attached to the rear side of the fixed cross beam, further preventing the U-shaped hanging plate from accidentally slipping off the fixed cross beam during use.
