Technical Field

[0001] The utility model relates to the technical field of noise reduction devices for ready-mixed concrete mixers, in particular to a device for solving noise pollution of ready-mixed concrete mixers. Background Art

[0002] As we all know, ready-mixed concrete mixers generate significant noise pollution during operation. The noise mainly comes from the operation of the drive motor, the collision between the mixing blades and the material, and the sound generated by the movement of the material. Being in a high-noise environment for a long time not only affects the health of the operators, but also interferes with the lives of the surrounding residents. Although traditional noise reduction measures such as equipment packaging and the use of sound-absorbing materials have certain effects, in actual applications, there are often problems such as complex installation, inconvenient maintenance or limited noise reduction effects. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a device for solving the noise pollution of the ready-mixed concrete mixer, which has the following beneficial effects:

[0016] The device for solving noise pollution of ready-mixed concrete mixers can quickly fix the sound insulation cover and the motor sound insulation shell by simply rotating the threaded column, which simplifies the daily maintenance and inspection process and reduces maintenance costs. The motor sound insulation shell tightly wraps the drive motor, blocking the main way for the motor noise to be directly transmitted to the outside world. Since the motor is usually one of the largest noise sources in the mixing equipment, this direct sound insulation measure greatly reduces the overall noise level. The combined use of the sound insulation cover and the sound insulation board extends to the entire body of the mixing equipment and both ends of the mixing equipment to form an all-round sound insulation barrier, which helps to absorb and isolate the secondary noise generated by material collision, mixing arm rotation, etc. during the mixing process, achieve more comprehensive noise control, and greatly reduce noise pollution, providing operators with a quieter and healthier working environment, reducing the risk of occupational diseases caused by long-term exposure to high-noise environments, and improving job satisfaction and retention rates.
