Embodiment 1

[0040] Such as Figure 1 ~ Figure 3 As shown, the radiator windshield structure for engineering machinery provided by the embodiment of the present invention includes an outer shell 1 and an inner sound-absorbing structure 2, wherein:

[0041] The inlet of the outer shell 1 communicates with the outlet of the inner sound-absorbing structure 2 .

[0042] The inner sound-absorbing structure 2 is provided with a sound-absorbing area (area with the function of absorbing noise) or a sound-absorbing member (a component with the function of absorbing noise), and the inner sound-absorbing structure 2 is also provided with a Venturi diversion wall 24, and the Venturi diversion The wall 24 is arranged on a side of the inner sound-absorbing structure 2 away from the outlet on the outer casing 1 .

[0043] Because in the radiator wind guide cover structure for construction machinery provided by the present invention, the inner sound-absorbing structure 2 is provided with a sound-absorbin...

Embodiment 2

[0058] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the inner layer sound-absorbing structure 2 in this embodiment includes a sound-absorbing block 21, wherein: the sound-absorbing block 21 is provided with an airflow channel, and the inlet of the airflow channel forms an inner layer The inlet of the sound-absorbing structure 2 and the outlet of the airflow channel form the outlet of the inner sound-absorbing structure 2 . The sound-absorbing block 21 is made of sound-absorbing material, and its part close to the outlet on the outer shell 1 is embedded in the outer shell 1, and the Venturi guide wall 24 is arranged on the sound-absorbing block 21 away from the outer shell side of the outlet on body 1.

[0059] The Venturi deflector wall 24 in the above structure is arranged on the side of the sound-absorbing block 21 away from the outlet on the outer shell 1, so the sound-absorbing block 21 omits the Venturi shell 22, which furth...

Abstract

The invention discloses a radiator wind scooper structure for an engineering machine and relates to the technical field of engineering machines. By the adoption of the radiator wind scooper structure for the engineering machine, the technical problem that in the prior art, the noise is high is solved. The radiator wind scooper structure for the engineering machine comprises an outer shell and an inner sound absorption structure. A flow inlet in the outer shell communicates with a flow outlet of the inner sound absorption structure. A Venturi flow guiding wall is arranged on the inner sound absorption structure. The radiator wind scooper structure is further provided with a sound absorption area or a sound absorption component. The Venturi flow guiding wall is arranged on the side, backing onto the flow outlet in the outer shell, of the inner sound absorption structure. The noise elimination effect and the noise reduction effect of the radiator wind scooper structure are improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a radiator wind guide cover structure for construction machinery. Background technique [0002] In order to meet the increasingly stringent national environmental protection regulations, protect the health and safety of the people, and improve the comfort and quality of products, manufacturers pay more and more attention to the noise of construction machinery. As the main noise source of construction machinery, even the largest noise source, the cooling fan is one of the main problems in the noise control of construction machinery. Technical researchers have taken many measures and methods to improve and optimize the fan, and the noise of the whole vehicle has also been significantly reduced. , but often the cooling fan is still the main noise source of the whole machine after improvement. Due to cost, technical and other reasons, the optimal matching of the fan it...
