Dustproof and noise-reducing handheld air pick for buildings

Abstract

The invention belongs to the field of building tools, and particularly relates to a dustproof and noise-reducing handheld air pick for buildings. The handheld air pick comprises a plunger valve, an air control mechanism is arranged on one side of the plunger valve, a hammering mechanism is arranged on one side, away from the plunger valve, of the air control mechanism, and a dust removal mechanism is arranged on one side, away from the air control mechanism, of the hammering mechanism. In the working process of the air pick, the dust removal mechanism collects dust through compressed air in the hammering mechanism, the air in the process blows a windmill to rotate, the air pressure in the windmill is reduced, dust in the working process is sucked into a dust accumulation cavity through a dust collection channel, and the dust is prevented from flying all around in the working process; and through compression of a noise reduction spring and noise reduction of a noise reduction block, noise generated when the noise reduction block knocks the wall of an air cylinder is reduced, noise generated when the wall of the air cylinder and a pickaxe drill rod are directly knocked is reduced, a compressed air bag is inflated through air needing to be discharged in the return stroke process of an impact hammer, lack of the air in the compressed air bag is avoided, and then the dust adsorption effect of a pressure change cavity is guaranteed.

Description

technical field [0001] The invention belongs to the field of construction tools, in particular to a dust-proof and noise-reducing hand-held jackhammer for construction. Background technique [0002] The hand-held air pick is a pneumatic tool that makes the piston hammer reciprocate by compressing the gas, and continuously strikes the pick. It is commonly used in mining and road construction. The pickaxe continuously hits the working surface to destroy it, so there will always be a tractor-like noise during the process of the hammer hitting the pickaxe, which will cause great noise damage to the workers' ears. When the pickaxe impacts the working surface, it will A large amount of dust is produced, which not only pollutes the air, but also causes breathing hazards to people. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and propose a dust-proof and noise-reducing hand-held jackhammer for co...
