[0002] High-power bulldozer is a kind of mechanical equipment commonly used in civil engineering. During the working process of the bulldozer, the engine needs to dissipate heat through the cooling fan. The overcooling fan will generate a lot of noise at high speed, resulting in serious noise pollution. Affect the working environment of the operator, for this reason, we propose a noise reduction device for cooling fans of high-power bulldozers

The invention discloses a noise reduction device for a high-power bulldozer cooling fan, and belongs to the technical field of bulldozer cooling fans. The device comprises a mounting base, a fan covercomprises an annular cover body, a sound insulation layer is arranged on the outer wall of the annular cover body, a sound absorption block layer is arranged on the inner wall of the annular cover body, a mounting disc is arranged in the middle of an inner cavity of the annular cover body, and a groove is formed in the front side of a mounting block on the rear side. According to the device, a light fabric layer, sound attenuation holes, the sound absorption block layer, a sound attenuation cavity and sound attenuation cotton strips are arranged; the mounting disc is driven by a driving device, and when blades rotate to blow air, generated noise is absorbed through the sound absorption block layer and the light fabric layer, sound waves enter the sound attenuation cavity through the soundattenuation holes, and the sound waves flow and differentiate in the sound attenuation cavity and are decomposed through the sound attenuation cotton strips; and meanwhile, the sound insulation layeris arranged so that the sound waves cannot be diffused outwards, the excellent sound insulation and noise reduction performance is achieved, and the working environment of operators is guaranteed.
Description
technical field [0001] The invention relates to the technical field of bulldozer cooling fans, in particular to a noise reduction device for a high-power bulldozer cooling fan. Background technique [0002] High-power bulldozer is a kind of mechanical equipment commonly used in civil engineering. During the working process of the bulldozer, the engine needs to dissipate heat through the cooling fan. The overcooling fan will generate a lot of noise at high speed, resulting in serious noise pollution. It affects the working environment of operators, so we propose a noise reduction device for cooling fans of high-power bulldozers. Contents of the invention [0003] The object of the present invention is to provide a noise reduction device for a cooling fan of a high-power bulldozer, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a...
