Description

Technical Field

[0001] This utility model relates to the field of landscape greening engineering technology, and more specifically, to a column-type hydroponic device. Background Technology

[0002] A column-type hydroponics system is a soilless cultivation device that suspends plant roots vertically within a column, supplying nutrient solution through a circulation or spray system. Its structure typically consists of a column frame, planting troughs, a nutrient solution storage tank, and a circulation system. It utilizes three-dimensional space to increase yield per unit area and achieves precise nutrient supply through automated control. Existing devices mostly moisten the root system through timed spraying, atomization, or drip irrigation. Some systems incorporate light and temperature / humidity control modules to form an intensive production system, widely used in the commercial cultivation of leafy vegetables, strawberries, and other crops. It offers advantages such as saving land resources, reducing the spread of pests and diseases, and facilitating environmental control.

[0003] In practical applications, some plants require little water, and insufficient nutrient solution can lead to inadequate contact between the nutrient solution and the plant roots. Since nutrient solutions are often applied through open circulation or intermittent spraying, localized over-wetting or dryness of the roots is common, especially in the lower and middle planting troughs. In these areas, the nutrient solution is easily unevenly distributed due to gravity, resulting in some roots being soaked for extended periods without oxygen or unable to obtain sufficient nutrients.

[0004] Therefore, we have made improvements to this and proposed a column-type hydroponic device. Utility Model Content

[0005] The purpose of this invention is to address the problem of insufficient contact between plant roots and nutrient solution. Because nutrient solution is often applied through open circulation or intermittent spraying, localized over-wetting or dryness of the roots frequently occurs.

[0006] In order to achieve the above-mentioned objectives, this utility model provides a column-type hydroponic device to improve the above-mentioned problems.

[0007] The application is as follows:

[0008] It includes a cylindrical nutrient solution tank and an elastic ring fixedly fitted on the nutrient solution tank. A planting platform is movably connected to the elastic ring. Both the elastic ring and the nutrient solution tank have connecting holes for the flow of nutrient solution.

[0009] The nutrient solution tank is fixedly connected to a spring that tilts the planting platform to one side.

[0010] A circular groove is provided on the planting platform along the same axis as the spring, and the bottom of the planting platform gradually decreases towards the horizontal plane of the circular groove to form a guide groove.

[0011] When the planting platform is tilted, the nutrient solution flows into the planting platform through the connecting hole and gradually converges towards the circular groove, allowing the planting platform to return to a horizontal state.

[0012] Preferably, the planting platform is positioned horizontally and the connecting hole is closed.

[0013] Preferably, a waste liquid box is fixedly connected to the bottom of the nutrient solution tank, and the planting platform and the waste liquid box are fixedly connected by a connecting pipe, and the inlet of the connecting pipe is on the same horizontal plane as the circular groove.

[0014] Preferably, the elastic ring includes a rigid central tube and elastic rings on both sides, and the diameter of the elastic tube is smaller than the diameter of the circular cavity at the connection between the implantation platform and the elastic ring.

[0015] Preferably, a lamp post is fixedly connected to the nutrient solution tank, and a reflective ring is attached to the planting platform to reflect light to the plant.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] To address the problem in existing technologies where insufficient nutrient solution leads to inadequate contact with plant roots due to limited water requirements for some plants, this application utilizes an inclined planting platform that automatically opens and closes the connecting holes to achieve automatic supply even in the absence of nutrient solution. Simultaneously, during the supply process, the nutrient solution is agitated and evenly distributed on the planting platform as the planting platform returns to a horizontal position, thus covering the plant roots and achieving uniform nutrient supply to each plant.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background art, some plants do not require much water, and insufficient nutrient solution can lead to inadequate contact with the plant roots.

[0027] To solve this technical problem, this utility model provides a column-type hydroponic device that can evenly distribute nutrient solution around the roots.

[0028] For details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A column-type hydroponic device specifically includes:

[0029] A cylindrical nutrient solution tank 1 and an elastic ring 2 fixedly fitted on the nutrient solution tank 1 are provided. A planting platform 3 is movably connected to the elastic ring 2. Both the elastic ring 2 and the nutrient solution tank 1 are provided with a connecting hole 21 for the nutrient solution to flow through. When the connecting hole 21 is not blocked by the elastic ring 2 and the planting platform 3, the nutrient solution in the nutrient solution tank 1 will gradually flow to the upper surface of the planting platform 3. Specifically, under normal circumstances, the planting platform 3 is in a horizontal state because it contains nutrient solution. When the nutrient solution in the planting platform 3 is exhausted, the spring 12 will lift the planting platform 3 and cause the planting platform 3 to squeeze the elastic part of the elastic ring 2 and expose the connecting hole 21, so that the nutrient solution flows to the planting platform 3.

[0030] A spring 12 is fixedly connected to the nutrient solution tank 1 to tilt the planting platform 3 to one side;

[0031] A circular groove 4 is provided on the planting platform 3 along the same axis as the spring 12. The bottom of the planting platform 3 gradually lowers to form a guide groove 5, which allows the nutrient solution to move gradually towards the circular groove 4. Since the circular groove 4 coincides with the spring 12 in the vertical direction, the nutrient solution overcomes the elastic force of the spring 12 and allows the planting platform 3 to return to a horizontal state. During this process, the nutrient solution converts the gravitational potential energy into kinetic energy flowing to one side, causing the nutrient solution to sway on the planting platform 3 and flow evenly through most of the root system, resulting in a more uniform dispersion of the nutrient solution.

[0032] When the planting platform 3 is tilted, the nutrient solution flows into the planting platform 3 through the connecting hole 21 and gradually converges towards the circular groove 4, causing the planting platform 3 to return to a horizontal state.

[0033] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 A column-type hydroponic device, wherein the planting platform 3 is in a horizontal state and the connecting hole 21 is closed. When the horizontal planting platform 3 is in a horizontal state, it completes the horizontal state when the elastic force of the spring 12 is balanced with the weight of the water flow, and the elastic force of the spring 12 is adapted to the sum of the weight of the plant and the water flow.

[0034] The bottom of the nutrient solution tank 1 is fixedly connected to a waste liquid box 7. The planting platform 3 and the waste liquid box 7 are fixedly connected by a connecting pipe 8. The inlet of the connecting pipe 8 is on the same horizontal plane as the circular trough 4. When the planting platform 3 is tilted, the bottom is filled with new liquid, while the old liquid flows through the connecting pipe 8 into the waste liquid box 7 when the horizontal plane rises.

[0035] The elastic ring 2 includes a rigid central tube and elastic rings on both sides. The diameter of the tube of the elastic ring 2 is smaller than the diameter of the circular cavity at the connection between the implantation platform 3 and the elastic ring 2, so that the implantation platform 3 can be swayed under the action of the spring 12.

[0036] A lamp post 6 is fixedly connected to the nutrient solution tank 1, and a reflective ring 9 is attached to the planting platform 3 to reflect the light to the plant. In conjunction with the bowl-shaped structure of the planting platform 3, the reflective ring 9 reflects the light from the lamp post 6 to the bottom of the leaves, making the photosynthesis of the plant stronger.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
