All-weather insect prevention protection device for greenhouse planting

Abstract

The invention relates to the technical field of insect prevention devices, and discloses an all-weather insect prevention protection device for greenhouse planting, which comprises a top plate and a trap lamp fixedly arranged at the center of the bottom of the top plate, the edge of the bottom of the top plate is fixedly connected with a connecting ring through a support frame, and the bottom of the connecting ring is fixedly provided with an air duct. A roller fan is fixedly arranged in the air duct through a fixing frame; the insect trapping lamp emits light, insects are attracted to approach by utilizing the phototaxis characteristic of the insects, the roller fan runs around the connecting ring to generate negative pressure, under the action of the negative pressure, the approaching insects can be sucked into the air cylinder and then fall into the bottom cylinder through the top cylinder and the exhaust cylinder, air is exhausted from the exhaust cylinder, and the insects are left in the bottom cylinder, so that the insect trapping effect is achieved. Pests in the greenhouse can be effectively trapped and killed, and the pests are prevented from gnawing crops. The device is novel in design and simple in structure, and has the advantage of all-weather deinsectization.

Description

technical field [0001] The invention relates to the technical field of anti-insect devices, in particular to an all-weather anti-insect protection device for greenhouse planting. Background technique [0002] In the planting of crops or vegetables in greenhouses, the more important point of attention is to prevent insects. Pests will seriously affect the growth and development of crops or vegetables. In traditional pest control methods, pesticides are generally sprayed to eliminate pests, but pesticides will remain on crops, posing a certain threat to human health. One way, gradually began to use physical insect traps, such as light trapping, to eliminate pests; [0003] For example, the Chinese patent publication number is: CN109349253B, which provides an intelligent light wave insecticidal lamp. The intelligent light wave insecticidal lamp includes: a drum fan; a driving part, which is connected to the drum fan; a lamp body shell, which is covered around the drum fan; th...

Problems solved by technology

[0005] Although the light trapping of the above-mentioned insecticidal device can effectively trap pests at night, its trapping effect is greatly weakened during the day, and it cannot achieve all-weather desinsection Effect;
