Abstract
The invention provides a powder-spreading bomb, and relates to a pest-killing device used in a forest. The bomb comprises a housing filled with pesticide powder. The housing has a shape of a round tube. The outer diameter of the housing forms sliding fit with the inner diameter of a launch tube on a pneumatic throwing device. A round-disc-shaped cover is arranged on the front port of the housing. The periphery of the cover fit with the front end of the inner hole of the housing with a slight interference way. The back port of the housing is sealed by a film. With the pneumatic throwing device used in fire-fighting and lifesaving industries, high-pressure gas makes the film recesses forward until broken, and the pesticide powder is pushed forward, such that the cover is also pushed forward when the powder moves forward with the housing. The cover is finally separated from the housing, and the housing tumbles forward in the air. Pesticide powder in the housing is spread out of the housing from the front and back ends of the housing. Drug throwing height and distance are increased, drug spreading is uniform, and drug delivery effectiveness is greatly improved. With the powder-spreading bomb, the danger of using fire in the forest is eliminated fundamentally.
