Illumination device for preventing floating dust and blocking light for greenhouse vegetable planting

Abstract

The invention discloses an illumination device for preventing floating dust and blocking light for greenhouse vegetable planting, wherein the illumination device structurally comprises a net eave, a blocking net, a light-supplementing illuminating lamp and floating dust absorption control feet, wherein the net eave is arranged at the periphery of the blocking net; the floating dust absorption control feet comprise soil stabilizing feet, an oil cavity net pulling groove, a top fixing end and an illumination expanding cover; the bottom end of the oil cavity net pulling groove penetrates throughthe top end of the soil stabilizing feet; when the outside floating dust day is serious, the floating dust is floated into the shed, so that the effect of light supplementing illumination is influenced; the device can be arranged on the periphery of the Chinese cabbage, and the Chinese cabbage can be covered; when the device is placed, embedded teeth and baffle body are subjected to the resistanceof the soil to drive the screw threads to drive the sleeve to rotate, so that an insertion rod can be rotated and screwed out along a limiting outlet; initially, a reverse pull buckle is clamped inside a forward rod to hook the soil, so that the reverse pull buckle can be separated from the forward rod with a little more power, and the main buckle head can be deployed along a force axis, so thatthe blocking net can surround the Chinese cabbage, and the Chinese cabbage can be smoothly cultivated.

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 ...

AI Technical Summary

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
