Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The technical scheme adopted in the present invention is a chimney denoising device for agricultural tractors, such as figure 1 As shown, it includes a noise removal pipe 1, one end of the noise removal pipe 1 is threadedly connected to the inlet pipe 2, the other end of the noise removal pipe 1 is connected to the outlet pipe 3, and the inner wall of the noise removal pipe 1 is fixed with a layer of sound-absorbing wall 4, and the surface of the sound-absorbing wall 4 is uneven Uneven, the noise-removing pipe 1 is installed with a sound-absorbing perforated plate 5 perpendicular to the direction of the pipe axis, and a plurality of tapered through-holes are opened on the sound-absorbing perforated plate 5, and the large opening end of the tapered through-hole is close to the inlet pipe 2, so that the noise When passing through, the di...

Abstract

The invention discloses an agricultural tractor chimney denoising device. The device comprises a denoising pipe, wherein one end of the denoising pipe is in threaded connection with an inlet pipe, theother end of the denoising pipe is connected with an outlet pipe, the inner wall of the denoising pipe is fixedly connected with a layer of silencing wall, the surface of the silencing wall is uneven, and a silencing porous plate perpendicular to the pipe axis direction is mounted in the denoising pipe. The device is provided with the silencing porous plate, and the purpose of silencing is achieved by utilizing conical through holes on the silencing plate, wherein the conical through holes are similar to a honeycomb structure, and the different distances of the noise in contact with the conical through holes, the reflection distance and the reflection path achieve the purpose of silencing; and meanwhile, the silencing wall is adopted, so that the noise is isolated through the thickness ofthe silencing wall, the noise is reflected through the uneven surface on the silencing wall, and the purpose of noise cancellation is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a chimney denoising device for an agricultural tractor. Background technique [0002] China has a vast land and abundant resources, and it is also a large agricultural country. There are about 1.5 billion mu of agricultural land, but the utilization rate of agricultural machinery is still very low compared to developed countries. Because our country has a vast territory, the level of purchasing agricultural machinery in rural areas is different, and the demand for agricultural machinery products in different terrains of rural plains, hills, grasslands, and mountains is also different. However, tractors have great advantages in terms of transportation and lowering. They have a large starting force and can easily tow more items, reducing time-consuming and labor-intensive physical labor, and can meet the needs of agricultural use in many areas of China.
