A lighting device for preventing floating dust and blocking light for growing vegetables in greenhouses

Abstract

The invention discloses a lighting device for preventing floating dust and light shielding for planting vegetables in a greenhouse. The structure includes a net eaves, a screen, a supplementary light, and floating dust absorption control feet. Feet, oil chamber pulling mesh groove, top fixing end, lighting expansion cover, the top of the soil stabilizing foot runs through the bottom of the oil chamber pulling mesh groove, when the dust outside is very serious, and it has floated into the shed, affecting the fill light To improve the lighting effect, the device can be installed on the periphery of the Chinese cabbage to cover the Chinese cabbage. When it is placed, the embedded teeth and the stopper will be resisted by the soil, and the thread will drive the sleeve to rotate, so that the rotating insert rod will move along the limit. At the beginning, the reverse pull buckle is stuck inside the forward rod, making it hook the inside of the soil. Just use a little more force to separate the reverse pull buckle from the forward rod, and the main buckle head will Expand along the force axis, so that the net will surround the Chinese cabbage, so that the Chinese cabbage cultivation can be carried out smoothly.

Description

technical field [0001] The invention belongs to the field of agriculture, and more specifically relates to a lighting device for preventing floating dust and blocking light for growing vegetables in greenhouses. Background technique [0002] In relatively dry areas in the north, because the outside climate is not suitable for growing Chinese cabbage, generally when Chinese cabbage needs to be planted in the north, it is planted in greenhouses, which can simulate the weather and temperature for planting, but there will be differences with the outside world. Connect it so that it can be ventilated. Dust weather often occurs in the north. The visibility is low and the pollution is serious. The sunlight that could have irradiated the greenhouse is blocked, and the sunlight is weak. If there is no open opening, the floating dust will run into the greenhouse. [0003] Based on the discovery of the inventors above, the existing lighting devices for agricultural greenhouses mainly ...

Problems solved by technology

[0004] The floating dust in the shed also affected the illumination of the emergency lighting on the Chinese cabbage. The lack of sunlight and the lack of sunlight simulating lights in the shed. If the weather lasts longer, it will easily affect the cabbage. yield of cabbage
