Background technique

Hydroponic technology is a kind of soilless cultivation technology. Its principle is to soak the root system of the plant directly in the nutrient solution. This nutrient solution can replace the soil and provide the plant with growth factors such as water, nutrition and oxygen, thereby helping the plant to grow normally. grow. When carrying out hydroponic cultivation, it is necessary to use a special hydroponic box or hydroponic rack, among which the hydroponic rack is the most widely used, and most of them are horizontal hydroponic racks at present.

At present, the technical problems existing in the hydroponics stand are as follows:

1. The existing conventional hydroponic racks are mostly single-layer or multi-layer horizontally arranged structures, and the materials are mainly PVC and other plastics. After long-term high-temperature sunlight and internal water pressure, aging and deformation will occur.

2. At the same time, the installation of fixed structures such as brackets requires a high level of technology and is difficult, and it will also age and deform, which will further cause the tank body of the hydroponic tank to tilt; and it needs to be assembled with different types of PVC pipes and adapter pipes, and there are many interface parts. , easily lead to water leakage and difficult maintenance.

Both of the above two conditions will lead to uneven liquid level in the hydroponic tank. When the tank body is long, it will cause no liquid (or part of the area) at one end and overflow of liquid at the other end, which will affect the growth of plants while wasting water and fertilizer. Water and fertilizer Sufficient areas grow normally, and where there is insufficient water and fertilizer, growth is stagnant or dead.

3. The structure of the traditional hydroponic rack device is complex, and it needs to be driven by a high-power water pump to realize the circulation of the nutrient solution in the hydroponic rack and increase the oxygen content of the nutrient solution. Otherwise, the plant root system will suffer from hypoxia and poison, which will affect the growth and eventually lead to production. The benefit is low and the input cost is high.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-5, an embodiment provided by the present invention is an inclined three-dimensional vegetable hydroponic stand, the main body of which consists of a hydroponic tank 1, a nutrient solution circulation structure 2 and a support structure 3; The cultivation tank 1 includes a hydroponic tank body 11 arranged in an inclined manner. There are cultivation holes 12 above the hydroponic tank body 11, and a liquid storage space 13 corresponding to the cultivation hole positions 12 is provided below the hydroponic tank body 11. A liquid surface partition 16 corresponding to the liquid storage space 13 is provided inside the hydroponic tank body 11 . The nutrient solution circulation structure 2 includes a water supply adapter 21, a water supply pipeline 22 connected to the water supply adapter 21, and a nutrient solution container 23. The nutrient solution container 23 is provided with a nutrient solution addition port 24, and a small water pump 25 is arranged inside. The upper water pipeline 22 is connected with a small water pump 25 for liquid supply. The support structure 3 is a general rigid support structure, which includes a support column 31 and a support base 32. The support column 31 can fix the hydroponic tank 1 with a fixed inclination angle by welding steel and other materials, and the lower end load-bearing support base 32 is fixed on the level ground, and The whole can bear the weight of a normal working hydroponics stand.

In this embodiment, the hydroponic tank 1 has at least two sections, and forms a downward-sloping ending connection structure from top to bottom as a whole. The inlet end of the first hydroponic tank 1 is connected to the outlet of the upper water pipeline 22 through the upper water adapter 21, and the outlet end of the last hydroponic tank 1 is connected to the liquid return of the nutrient solution container 23 through the liquid return adapter 26. The mouths are connected; the head and the tail of each hydroponic tank are connected through the hydroponic tank adapter 14 to realize the reversing transfer.

In this embodiment, the nutrient solution circulation process is completed by combining the hydroponic tank 1 and the nutrient solution circulation structure 2 into a connected whole. In order to realize the circulation of nutrient solution and ensure the normal growth of cultivated vegetables, the specific process is as follows:

Add the well-proportioned nutrient solution into the nutrient solution container 23 that is large enough, power the water pump 25, and the nutrient solution in the nutrient solution container 23 moves upward under the action of the water pump 25, flows through the upper water pipeline 22, and then passes through the upper water The adapter 21 enters into the first hydroponic tank 1 .

Further, when the nutrient solution enters the first hydroponic tank body 11, it flows through a certain distance and then enters the first liquid storage space 13. As the liquid continues to flow in, the nutrient solution level continues to rise until it reaches the liquid level The partitioned concave point overflows, and then flows to the second liquid storage space 13, and then the process is repeated until the nutrient solution overflows from the last liquid surface partition 16 of the hydroponic tank 1 in this section.

At this time, if only one section of the hydroponic rack is assembled, the nutrient solution will directly flow into the nutrient solution container 23 through the liquid return adapter 26, so as to realize the circulation of the nutrient solution. If the hydroponic stand is composed of more than two hydroponic tanks 1, the nutrient solution flows through the hydroponic tank adapter 14 and enters the hydroponic tank body 11 of the second section after overflowing from the last liquid surface partition 16 , at this time, the nutrient solution will repeat the above-mentioned flow path in the hydroponic tank in this section of the hydroponic tank until it flows to the last liquid level of the last section of the hydroponic tank, and finally enters the nutrient solution through the liquid return adapter 26 Among the liquid container 23, complete the circulation of this nutrient solution.

Further, after a cycle of nutrient solution is completed, there is sufficient nutrient solution in the liquid storage space 13 below each cultivation hole in this embodiment. At this time, the roots of the cultivated vegetables are washed and placed in the cultivation cage. 15, the root system of the plant can be contacted with the nutrient solution in the liquid storage space to complete the cultivation of vegetables.

Furthermore, after the nutrient solution flows through each liquid surface partition structure 16, it will continue to flow for a certain distance before entering the next liquid storage space. During this period, the contact area between the liquid and the air is relatively large, which can fully increase the oxygen content in the water. Make sure the plants grow healthy.

Furthermore, according to the daily climate conditions and the growth state of vegetables, the water pump is switched on and off at regular intervals, which can save water and fertilizer, save energy and protect the environment, and vegetables can grow normally in this environment.
