Whirlwind negative-pressure agricultural pest capturing device

Abstract

The invention discloses a whirlwind negative-pressure agricultural pest capturing device. The device comprises a housing, a capturing cavity, an attractant storage cavity and a whirlwind cavity, and the capturing cavity is formed in the housing; one-way through ports are formed in the middles of the two side walls of the housing, a pest collecting groove is formed in the lower portion of the capturing cavity, and light traps are fixedly installed at the parts, corresponding to the one-way through ports, of the two sides of the interior of the capturing cavity; first pest killing electric netsare fixedly installed on the parts, away from the sides of the one-way through ports, of the light traps; the attractant storage cavity is formed between the first pest killing cavities; the whirlwindcavity is formed in the top of the capturing cavity; the lower portion of the whirlwind cavity is an arc-shaped adhesive plate which is fixedly installed in the capturing cavity, and an air suction port is formed in the middle of the adhesive plate. Compared with the prior art, the device has the advantages of high capturing efficiency, time saving and labor saving, and multi-stage thorough capturing on insects can be achieved, and the healthy growing of crops can be fully ensured.

Problems solved by technology

[0003] At present, the main method of prevention and control of agricultural diseases and insect pests is mainly to use chemical pesticides, which has the advantage of quickly killing pests and controlling the outbreak of pests. There are a large amount of pesticide pollution residues on agricultural products, which has a negative impact on the ecological environment, and chemical pesticides pose a threat to human health. At present, there are many types of insect traps on the market, but the angle of the insecticidal grid in the existing insect traps cannot be adjusted. Catch the pests at a fixed angle, resulting in a reduction in the efficiency of the insects; if things go on like this, the purpose of protecting crops cannot be achieved
