Cyclone negative pressure airflow insect catching machine

Abstract

The invention relates to an insect catching machine, in particular to a cyclone negative pressure airflow insect catching machine. The cyclone negative pressure airflow insect catching machine is formed by a rack, a motor, an exhaust fan, a wind forming box, a negative pressure fan housing, an air draft barrel and an air return pipe; the negative pressure fan housing is arranged on the rack; the motor and the exhaust fan are arranged at the top of the negative pressure fan housing; the exhaust fan is communicated with the negative pressure fan housing by the air draft barrel; the air draft barrel is sleeved with the wind forming box; the wind forming box is communicated with the negative pressure fan housing by the air return pipe; the wind forming box is communicated with an air outlet of the exhaust fan by a communication pipe. The insect catching machine has a simple structure and a good killing effect, cannot cause damage to the environment and human body health and solves the problems that an existing physical method cannot achieve an effect of totally killing insects, and an existing chemical method easily causes damage to the environment and easily enables chemical substances to be left on vegetables to damage human body health of people; guarantee is provided for people to eat relieved vegetables; the cyclone negative pressure airflow insect catching machine is particularly suitable for killing injurious insects in vegetable farmland.

Description

technical field [0001] The invention relates to an insect catcher, in particular to a cyclone-type negative pressure airflow insect catcher. Background technique [0002] At present, the control of vegetable pests is mainly based on physical and chemical methods. The most common physical method is to place a luminous source in a transparent container with holes around it, and use the principle of light-loving pests to lure them into the holes and fall into the container to achieve the purpose of hunting. This method is harmful to the environment and vegetables. It does not cause harm, but it can only act on winged pests, and cannot achieve the purpose of killing all of them. The chemical method is mainly spraying pesticides. The chemical method has a better killing effect, but long-term use will cause the pests to develop resistance to pesticides. To achieve the purpose of killing, the amount of pesticide and the frequency of spraying must be increased. Lead to pesticide r...

The chemical method is mainly spraying pesticides. The chemical method has a better killing effect, but long-term use will cause the pests to develop resistance to pesticides. To achieve the purpose of killing, the amount of pesticide and the frequency of spraying must be increased. Lead to pesticide residues on vegetables, endangering people's health
