Problems solved by technology

[0002] When the traditional excavator breaker is used to chisel the concrete of old buildings, the breaker is generally exposed to the outside when it is working. When the excavator is working, the noise is directly transmitted in the air medium, and the noise reduction treatment is not performed at the sound source, which is likely to cause noise pollution. ; During the process of excavator chiseling dust, protective measures are taken, and dust spreads randomly in the air, which is easy to cause air pollution

Abstract

The invention relates to the field of demolition of buildings, in particular to a dust prevention and noise reduction device for concrete reconstruction chiseling and a using method thereof. The dustprevention and noise reduction device for concrete modification chiseling comprises a breaking hammer (1) and is characterized by further comprising a sleeve (2), a drill rod (3) and a rubber sleeve (4), wherein the top end of the sleeve (2) is embedded in the bottom end face of the breaking hammer (1), the top end of the drill rod (3) is movably arranged in the sleeve (2) and blocked by the bottom end of the sleeve (2), and the rubber sleeve (4) is hooped on the outer side surface of the drill rod (3). The using method of the dust prevention and noise reduction device for concrete reconstruction chiseling is characterized by being implemented according to the following steps in sequence of: 1, mounting the breaking hammer; 2, mounting the rubber sleeve; 3, crushing; and 4, dismantling. According to the device and the method, noise is reduced, and dust is reduced.

Description

technical field [0001] The invention relates to the field of demolition of buildings, in particular to a dust-proof and noise-reducing device for concrete reconstruction and chisel removal and a method for using the same. Background technique [0002] When the traditional excavator breaker is used to chisel the concrete of old buildings, the breaker is generally exposed to the outside when it is working. When the excavator is working, the noise is directly transmitted in the air medium, and the noise reduction treatment is not performed at the sound source, which is likely to cause noise pollution. ; In the process of excavator chiseling dust, protective measures are taken, and dust spreads randomly in the air, which is easy to cause air pollution. Contents of the invention [0003] In order to overcome the defects of the prior art and provide a demolition method for reducing noise and dust, the invention discloses a dust-proof and noise-reducing device for concrete recons...
