Description

Technical Field

[0001] This utility model relates to the field of biotechnology, and in particular to a circulating hydroponic planting box. Background Technology

[0002] With the development of modern agricultural technology, soilless cultivation has become an important development direction in the planting industry due to its high resource utilization rate and strong environmental adaptability. Among them, hydroponics, as one of the core technologies of soilless cultivation, has attracted much attention due to its unique advantages. Specifically, hydroponics provides crops with the nutrients they need for growth directly through nutrient solution, without relying on soil. This not only achieves faster crop growth and shorter crop rotation cycles, but also avoids the tedious processes of land preparation and loosening in traditional soil cultivation, significantly reducing labor input. At the same time, the hydroponic environment is easy to control, which can effectively reduce the incidence of crop diseases, ensure the green and ecological attributes of products, and the yield per unit area is significantly higher than that of traditional soil cultivation. These outstanding features have led to the widespread application of hydroponics in various scenarios such as facility agriculture and home gardening, and it has always maintained its status as a popular technology in the planting industry. To meet the application needs of hydroponics, hydroponic planting boxes have emerged as integrated planting equipment. These boxes enable nutrient solution circulation, stable control of nutrient solution parameters, and purification, providing convenient core equipment for hydroponics. However, in actual use, existing hydroponic planting boxes still have unresolved technical shortcomings: during the crop growth cycle, residual seedling substrate, dead seedlings, and shed old roots and leaves accumulate in the planting box. If these wastes are not treated promptly, they can contaminate the nutrient solution, breed harmful microorganisms, and consequently affect normal crop growth, even causing secondary diseases and undermining the green ecological advantages of hydroponics. Therefore, regular cleaning of these wastes is essential.

[0003] Currently, waste disposal in existing hydroponic planting boxes mainly relies on manual operation. This involves growers periodically opening the boxes and manually sorting and removing residual seedling substrate, dead seedlings, and old roots and leaves. This manual cleaning method has significant drawbacks: firstly, the cleaning process requires interrupting planting operations and is cumbersome, resulting in low efficiency and making it unsuitable for the high-efficiency production demands of large-scale hydroponic cultivation; secondly, manual cleaning requires continuous physical labor from growers, leading to high labor intensity and increased planting costs over long periods; furthermore, the thoroughness of manual cleaning depends on the operator's experience and attention to detail, which can result in incomplete cleaning and the potential risk of nutrient solution contamination. In summary, the existing method of manually cleaning up waste in hydroponic planting boxes suffers from problems such as low efficiency, high labor intensity, and unstable cleaning results, which restricts the full realization of the advantages of hydroponic planting technology and has become a key bottleneck affecting the large-scale promotion of hydroponic planting and the improvement of application experience. Therefore, there is an urgent need for a hydroponic planting box related technical solution that can replace manual cleaning, improve waste treatment efficiency, and reduce labor intensity.

[0004] The purpose of this invention is to provide a circulating hydroponic planting box to address the defects and shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses a circulating hydroponic planting box, comprising a box body and a partition fixed inside the box body; the partition is used to divide the box body into a sedimentation zone and a liquid storage zone; the partition is provided with multiple grid holes; a filter bag is provided in the sedimentation zone; the inlet of the filter bag is connected to a return water pipe; and a pumping device is provided inside the liquid storage zone.

[0006] Furthermore, the pumping device includes a liquid supply pipe, a check valve, and a water pump; the water pump is located in the liquid storage area; the outlet of the water pump is connected to the liquid supply pipe; and the check valve is connected to the liquid supply pipe.

[0007] Furthermore, the number of the pumping devices is two.

[0009] Furthermore, a filter plate is fixed inside the liquid storage area; the filter plate and the side wall of the liquid storage area form a filter cavity; the water pump is located inside the filter cavity.

[0010] Furthermore, a sensor bracket is installed inside the liquid storage area; a liquid level sensor and an EC sensor are fixed inside the sensor bracket; and a water inlet and a fertilizer inlet are connected to the tank.

[0011] Furthermore, a heating rod is fixed inside the liquid storage area; two cold water pipe interfaces are connected inside the liquid storage area.

[0012] With the above structure, the beneficial effects of this utility model are as follows: the pumping device pumps the nutrient solution from the storage area into the hydroponic planting area; the liquid in the hydroponic planting area is pumped from the return pipe into the filter bag for filtration by the pump body built into the hydroponic planting area; the filter bag intercepts and accumulates larger pollutants such as impurities and rotten roots in the planting area, which are then decomposed inside the filter bag.

This filtration structure ensures that the nutrient solution entering the hydroponic planting area from the pumping device is cleaner, with high filtration efficiency and good filtration effect, reducing labor intensity; moreover, the circulating nutrient solution allows the nutrient solution in the hydroponic planting area to come into contact with oxygen in the air, increasing dissolved oxygen levels and allowing the plant roots to breathe fully.

The filter bag 10 is a PP polypropylene filter bag, and the bottom of the PP polypropylene filter bag is sealed with rattan cotton to relieve pressure. The pumping device pumps the nutrient solution from the storage area 8010 into the hydroponic planting area. The liquid in the hydroponic planting area is pumped through the return pipe 11 into the filter bag 10 for filtration. The filter bag 10 intercepts and accumulates larger contaminants such as impurities and rotten roots, which are then decomposed within the bag.
