Noise reduction chamber

Abstract

The invention discloses a noise reduction chamber used for reducing operating noise of a concrete pump. The noise reduction chamber comprises a hood body (3) for containing the main body of the concrete pump, a hopper hood (1) used for containing a hopper of the concrete pump and communicated with the hood body, and a ventilator. A lateral wall of the hood body (3) is provided with an inlet-outletgate (31) for facilitating the entering and exiting of the concrete pump into or out of the noise reduction chamber. The noise reduction chamber is specially designed for the concrete pump. The hopper hood (1) prevents the noise of the concrete pump from being transferred outside through a hopper part, effectively isolates the noise from the outside environment and reduces the noise pollution tothe environment when the concrete pump works, thereby effectively isolating and absorbing various noises generated during the operation of the concrete pump and reducing the noise pollution caused bythe concrete pump.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a noise reduction chamber for concrete pumps. Background technique [0002] With the rapid development of my country's economic construction, the use of concrete pumping equipment is becoming more and more extensive. [0003] Concrete pump is a modern construction equipment for concrete pumping construction. It is widely used in modern city construction, airport, road and bridge construction, water conservancy, electric power, energy construction and other concrete construction projects. [0004] However, during the construction process of the concrete pump, it will generate relatively severe vibration, and then generate relatively large vibration noise; Air noise and fan noise caused a lot of noise pollution to the environment, which could not meet the low-noise operation requirements in the bustling downtown area. [0005] Therefore, how to reduce the noise poll...
