Description

Technical Field

[0001] The utility model relates to the technical field of storage, in particular to a storage insect-killing device. Background Art

[0002] During the storage process, wheat is easily harmed by a variety of storage pests, among which the most serious storage pests are wheat moth, corn weevil and grain borer. Wheat moth mainly feeds on wheat grains with larvae. The adult wheat moth lays eggs in the ventral groove of the wheat grains. The larvae drill into the seeds from the ventral groove and feed on the substances in the grains, making the wheat lose its edible value and causing economic losses.

[0003] At present, the common way to eliminate pests in wheat storage is to place the wrapped wheat fumigant into different locations in the granary. The ingredients of wheat fumigant are aluminum powder and red phosphorus, and it is often used as a drug for fumigating granaries. The efficacy of wheat fumigant is generally about 10 days. It is often used in open granaries or granaries with poor sealing performance. However, this pest control method cannot ensure that the volatile smell of the fumigant evenly covers the entire barn, resulting in dead corners for pest control deep in the granary, resulting in incomplete pest control, difficulty in finding, and inconvenience in replacing new wheat fumigant. Utility Model Content

[0004] In order to solve the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a storage insecticide device, which can cover the surroundings of the barn with insecticidal gas, and the insecticidal gas can flow and gather toward the middle from all directions, thereby realizing comprehensive insecticide operation on the internal environment of the barn, greatly improving the insecticide effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Provided is a storage pest control device, comprising a flow distribution bottom plate, an air inlet pipe and a plurality of jet pipes, wherein a plurality of vertical plates are fixed to the peripheral side of the flow distribution bottom plate, the peripheral side of the jet pipe is fixedly connected to the vertical plates, a plurality of air outlet holes are opened on the upper surface of the flow distribution bottom plate, and a return pipe is fixed at the middle position of the upper surface of the flow distribution bottom plate, and a plurality of groups of return holes are opened on the peripheral side of the return pipe;
