Description

Technical Field

[0001] The utility model relates to the technical field of grain storage insect prevention, in particular to an insect prevention device for a grain storage ventilation opening. Background Art

[0002] For a large amount of grain stored in a warehouse, in order to adjust the temperature in the warehouse, ventilation openings are provided on the walls of the warehouse, and axial flow fans are arranged at the ventilation openings. Mechanical ventilation of the air flow in the warehouse is realized through the axial flow fans, so as to realize the adjustment of the temperature in the warehouse.

[0003] At present, in order to prevent insects from entering, an insect prevention net is arranged at the ventilation opening, which can prevent larger pests from entering the grain storage, but smaller pests may still enter the grain storage, so its insect prevention effect is general. Moreover, some pests will lay eggs on the insect prevention net, and it is easy to cause the blockage of the insect prevention net structure after long-term use. The existing grain storage ventilation structure is not convenient for directional ventilation of the humid places in the grain storage. Content of the Utility Model

[0004] In order to overcome the above technical problems, the purpose of the utility model is to provide an insect prevention device for a grain storage ventilation opening. Four insect prevention net plates are slidably connected at equal intervals in a chute frame to prevent most pests from entering the grain storage. Insect attracting lamps are arranged on both sides of the insect prevention net plates to induce the pests at the ventilation opening. Pouring holes and collecting boxes are arranged at the bottom of the insect prevention net plates. The broad-spectrum fumigant insecticide in the collecting boxes can be used to fumigate and kill the induced pests, and then fall into the collecting boxes through the pouring holes to complete the collection. After the collecting boxes are pulled out from the storage board, it is convenient to clean the pest corpses. The output end of the servo motor can drive the disc to rotate, so as to drive the driving column to slide back and forth in the chute rod. Therefore, the U-shaped plate can be driven to slide in the hollow shell, so as to drive the two moving plates to reciprocate, so that the cleaning brush hairs on the side walls of the moving plates can clean the mesh holes of the insect prevention net plates, so as to sweep away the blocked eggs, dust, etc., so as to facilitate the ventilation of the grain storage.

[0005] The purpose of the utility model can be realized by the following technical solutions:

The cleaning mechanism can drive two moving plates to reciprocate, so as to clean a plurality of insect-proof net plates regularly, thereby improving the smoothness at the ventilation opening.

[0009] Furthermore, a driving motor is fixedly connected to the inner wall of the connecting pipe. A plurality of ventilation fan blades are fixedly connected to the output end of the driving motor at equal intervals in a ring shape. By driving the ventilation fan blades to rotate by the driving motor, fresh air can be introduced at the air inlet pipe, and then the fresh air is introduced into various parts of the granary through a plurality of branch pipes.

[0010] Furthermore, two pouring holes are opened at the bottom of the hollow shell. A receiving plate fixedly connected to the hollow shell is arranged at the bottom of the pouring hole. A collecting box is slidably sleeved in the receiving plate. A broad-spectrum fumigant is placed inside the collecting box. Insects induced过来 can be fumigated and killed by the broad-spectrum fumigant such as aluminum phosphide, so the pest prevention effect can be improved.

[0011] Furthermore, insect attracting lamps are fixedly connected to the inner top of the hollow shell on both sides of the chute frame. The insect attracting lamps can induce pests at the ventilation opening to the insect-proof net plates.

[0012] Furthermore, two moving plates are symmetrically fixedly connected to the end of the L-shaped plate. Cleaning brushes are fixedly arranged on the opposite side walls of the two moving plates. The moving plates can drive the cleaning brushes to brush back and forth on the insect-proof net plates, so as to facilitate cleaning the eggs and dust in the mesh holes.
