Description

Technical Field

[0001] The utility model relates to the technical field of nutrient solution filling, and more specifically to a nutrient solution filling structure for a hydroponic planting box. Background Art

[0002] Hydroponics is an agricultural technology that cultivates plants using water solvents containing mineral nutrient solutions instead of soil. It has many advantages, including more precise nutrient and environmental control, higher plant growth rate and yield, and water and space saving, and has been widely used.

[0003] The core of hydroponic planting technology is nutrient solution. During the hydroponic planting process, nutrient solution needs to be added to the planting box regularly and quantitatively to ensure the normal growth of plants. Some nutrient solution supply systems currently used cannot quantitatively inject nutrient solution into multiple groups of planting boxes, so we proposed a hydroponic planting box nutrient solution filling structure to solve the above problems.

[0012] Furthermore, several groups of the planting boxes are distributed linearly.

[0013] Furthermore, the nutrient solution supply system also includes: a nutrient solution storage tank and a pump, wherein the liquid inlet end of the pump is inserted into the interior of the nutrient solution storage tank through a first pipe, and the liquid outlet end of the pump is connected to the main pipe through a second pipe.

[0014] Furthermore, it also includes:

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] (1) This solution, by designing a container, is provided with a slow-flow structure between the container and the planting box, a liquid inlet pipe is fixedly connected to the side of the container, a sliding plate and a floating ball are designed at the port of the liquid inlet pipe, and the main pipeline synchronously supplies nutrient solution to the containers corresponding to the multiple groups of hydroponic cover plates. The design of the slow-flow structure makes the nutrient solution entering the container flow out slowly (in a short period of time, the outflow of nutrient solution in the container can be ignored). When the nutrient solution accumulates in the container, the liquid makes the floating ball and the sliding plate slide upward to block the port of the liquid inlet pipe. After ensuring that the containers corresponding to the multiple groups of hydroponic cover plates are filled with nutrient solution, the nutrient solution supply system stops supplying liquid, and then the nutrient solution in the container slowly flows down, so as to realize quantitative injection of nutrient solution into the multiple groups of planting boxes;

[0024] (2) In this scheme, a drainage trough is designed, which extends along the distribution direction of several groups of hydroponic cover plates. An overflow port is opened on one side of the planting box facing the drainage trough, so that liquid overflowing from multiple groups of planting boxes can be collected to ensure that liquid will not accumulate in the site.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0033] Embodiment 1:

[0034] See also Figure 1-Figure 5 A nutrient solution filling structure for a hydroponic planting box includes: a plurality of planting boxes 6, a plurality of hydroponic cover plates 1 and a nutrient solution supply system. The hydroponic cover plates 1 are installed at the top ports of the planting boxes 6. The nutrient solution is stored inside the planting boxes 6. Crops are planted on the hydroponic cover plates 1. The roots of the crops are immersed in the nutrient solution inside the planting boxes 6. The nutrient solution supply system is used to add nutrient solution to the inside of the planting boxes 6.

[0035] In the present scheme, the nutrient solution supply system has a main pipeline 4 extending along the distribution direction of several groups of hydroponic cover plates 1, and a container 8 is fixedly installed on each group of hydroponic cover plates 1. A slow flow structure is arranged between the container 8 and the planting box 6, and the slow flow structure enables the liquid inside the container 8 to slowly flow into the planting box 6. A liquid inlet pipe 9 is fixedly connected to one side of the container 8, and a branch pipeline 4a corresponding to the liquid inlet pipe 9 is arranged on the side of the main pipeline 4. The branch pipeline 4a is fixedly connected to the liquid inlet pipe 9. The nutrient solution sent along the main pipeline 4 enters the liquid inlet pipe 9 through the branch pipeline 4a, and then enters the container 8 through the liquid inlet pipe 9. Due to the existence of the slow flow structure, the nutrient solution accumulates inside the container 8, and a sliding plate 14 is slidably installed on the inner side of the container 8. The sliding plate 14 corresponds to the port of the liquid inlet pipe 9, and a float 15 is fixedly connected to the side of the sliding plate 14. The liquid level of the nutrient solution accumulated inside the container 8 rises, causing the float 15 to float upward, thereby pushing the sliding plate 14 to slide upward to block the port of the liquid inlet pipe 9.

[0036] When in use, the nutrient solution supply system can fill the main pipeline 4 with nutrient solution in about 30 seconds, and pass through the branch pipelines 4a to enter the containers 8 corresponding to the hydroponic cover plates 1. The containers 8 corresponding to the hydroponic cover plates 1 near the liquid inlet end of the main pipeline 4 are filled first. After the containers 8 of the hydroponic cover plates 1 near the liquid inlet end of the main pipeline 4 are filled with nutrient solution, the liquid inlet pipe 9 of the container 8 of the hydroponic cover plates 1 near the liquid inlet end of the main pipeline 4 is blocked. After all the subsequent containers 8 are full, the nutrient solution supply system is stopped to fill with nutrient solution.

[0037] In one embodiment, in order to facilitate the arrangement of the main pipeline 4, several groups of planting boxes 6 are distributed linearly.

[0038] In one embodiment, the nutrient solution supply system also includes: a nutrient solution storage tank 2, a pump 3, the liquid inlet end of the pump 3 is inserted into the interior of the nutrient solution storage tank 2 through a first pipe, and the liquid outlet end of the pump 3 is connected to the main pipe 4 through a second pipe.

[0039] The pump 3 works to deliver the nutrient solution in the nutrient solution storage tank 2 to the main pipeline 4, and then the nutrient solution is diverted by the branch pipeline 4a on the main pipeline 4.

[0040] In one embodiment, it also includes: a drainage trough 5, which extends along the distribution direction of the plurality of hydroponic cover plates 1, and is fixedly connected to a planting box 6, and an overflow port 10 is provided on a side of the planting box 6 facing the drainage trough 5.

[0041] When the liquid level inside the planting box 6 is too high, the liquid flows into the drainage trough 5 through the overflow port 10, and then is guided out by the drainage trough 5 to avoid flowing to the ground on site.

[0042] In one embodiment, a plurality of pier grooves 7 are provided on the top of the hydroponic cover 1, each pier groove 7 corresponds to a plant planting position, and each pier groove 7 includes an annular net 7a and an annular plate 7b fixedly connected to the bottom end of the annular net 7a. The annular net 7a is water-permeable and the center of the annular plate 7b has a center hole, which is conducive to the roots of the plants extending downward into the planting box 6.

[0043] In one embodiment, the slow flow structure includes: a first opening 11 opened on the inner bottom surface of the container 8 and a pad 12 arranged on the inner bottom of the container 8, a second opening 13 is opened on the pad 12, and the first opening 11 and the second opening 13 are staggered.

[0044] The liquid inside the container 8 can flow into the planting box 6 only after passing through the second opening 13 , the gap between the pad 12 and the inner bottom surface of the container 8 , and the first opening 11 .

[0045] In one embodiment, a limiting block 16 is fixedly connected to the inner wall of the container 8 and located above the pad 12. The limiting block 16 is used to limit the upward movement of the pad 12 to ensure the stability of the slow-flow structure.

[0046] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
