Noise reduction device for crusher

Abstract

The invention discloses a breaker noise reduction device. The breaker noise reduction device can reduce noise and reduce environmental noise pollution. The breaker noise reduction device comprises a breaker machine body, the breaker machine body is provided with an inner cavity, and a protective layer, a sound insulation layer and inner wall wear-resisting layers are arranged on the inner wall ofthe inner cavity from outside to inside in sequence. The sound insulation layer is filled with sound absorption materials. A sound insulation cover is arranged above the inner cavity of the breaker machine body, a feeding door is arranged on the sound insulation cover, a sound insulation damping base is arranged below the breaker machine body, and a spring and sound insulation damping devices arearranged between the sound insulation damping base and the breaker machine body. The breaker noise reduction device can effectively reduce the noise generated by a breaker, avoids rearranging noise reduction equipment after the breaker is transferred to a field, and reduces the noise reduction cost; and the noise pollution to the environment can be reduced.

Description

technical field

[0001] The invention relates to the field of crusher noise reduction, in particular to a crusher noise reduction device. Background technique

[0002] As we all know: during the crushing process, the crusher will generate a lot of noise; it will cause great noise pollution to the surrounding environment.

[0003] In the construction site, noise pollution is one of the main environmental pollution. According to the "Environmental Noise Emission Standards for Construction Site Boundary", during the construction period, the noise at the construction site boundary should not exceed 70 decibels during the day and 55 decibels at night. However, the noise of the crusher far exceeds the noise emission standard, and the noise caused by it must go through noise reduction measures to meet the standard.

[0004] Generally, in actual work, the methods to control noise pollution mainly include reducing the sound level of equipment, reducing nighttime construction, monito...
