Description

Technical Field

[0001] The utility model relates to a hydroponic planting frame with ventilation and irrigation functions, belonging to the technical field of ventilation and irrigation of hydroponic planting frames. Background Art

[0002] Plant factories have been proposed since the 20th century and have been continuously developed and promoted. Planting methods and structures have gradually improved and diversified. The most common one is the shelf type. However, the shelf planting mode has the highest space utilization efficiency and high output per unit volume. This high-density planting mode has high requirements for air supply effects. For hydroponic plants, when the ventilation effect is not good, the transpiration of the plants is small, the water flow rate inside the plants is slow, and the root system of the plants cannot absorb well, resulting in calcium deficiency and core burn symptoms.

[0003] In the prior art, one or more fans are generally arranged on one side of the planting rack to ventilate the entire planting rack through the fans. This side ventilation method has the following defects: on the one hand, the side facing the wind receives a large amount of wind, while the side facing away from the wind receives a small amount of wind, so that the plants on the planting rack are not evenly exposed to the wind; on the other hand, when the wind is blown to the plants from the side, they are blocked by the layers and the plants themselves, and the wind receiving effect is not good.

[0004] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In view of the deficiencies in the background technology, the utility model provides a hydroponic planting rack with ventilation and irrigation functions, which can make the plants on the planting rack receive wind evenly and effectively, and can automatically fertilize and irrigate the plants on the planting rack.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A hydroponic planting rack with ventilation and irrigation functions, comprising a planting rack, wherein the planting rack is a multi-layer rack arranged up and down, a planting tray is placed on the layer rack, and plants are planted in the planting tray;

[0008] The planting rack is equipped with a ventilation system, which includes a blower and an air duct. The air duct includes a vertically arranged main air duct. A branch air duct is provided directly above each layer of the shelf. The branch air duct is connected to the main air duct. A plurality of air outlets are evenly arranged directly below the branch air duct.

[0009] Furthermore, there is only one blower, which is arranged at one end of the planting rack. The main air duct is also arranged at one end of the planting rack. The blower supplies air to the main air duct, and transports it to the branch air duct through the main air duct, and finally discharges it from the outlet of the branch air duct.

[0010] Furthermore, an air blower is respectively provided at both ends of the planting rack, and an air blower is also provided in the middle position of one side of the planting rack. Each air blower is equipped with a main air duct, and each main air duct is connected to the branch air ducts of each layer.

[0011] Furthermore, the planting rack is equipped with an irrigation system, which includes a main water pipe arranged on the top of the planting rack, and each planting plate on the top layer of the planting rack is connected to the main water pipe through a downpipe.

[0012] Furthermore, the planting trays on the upper and lower layers that are adjacent to each other on the planting rack are connected through a downpipe.

[0013] Furthermore, a water tank is provided at the bottom of the planting rack, and the planting tray at the bottom of the planting rack is connected to the water tank through a downpipe.

[0014] Furthermore, the irrigation system also includes a water-fertilizer mixer, which pumps water from the water tank into the interior of the mixer through a pumping pipe, adds fertilizer, and then sends it into the main water pipe through a water supply pipe.

[0015] Furthermore, the irrigation system also includes a water reservoir, in which a water pump is provided, and water is replenished into the water tank through the water pump.

[0016] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0017] 1. The air outlet of the branch air duct faces the plants in the planting tray, and the multiple air outlets at the lower end of the branch air duct can evenly supply air to the plants below it from the front; the exhausted air can blow directly to the plants from the front, which has a good air volume utilization effect and reduces the air volume loss caused by the obstruction of the planting rack and the plants themselves. In addition, the plants in various places receive uniform air volume.

[0018] 2. The water-fertilizer mixer adds fertilizer to the water flow while providing water flow power. The water flows from the main water pipe through the downpipe into the planting tray, and flows downward from top to bottom through the downpipe in sequence, and finally flows into the water tank, forming a water cycle. It can realize uninterrupted water circulation, continuously provide water and nutrients to plants, and promote plant growth.
