Abstract

The invention discloses a diesel engine silencer used for high-power agricultural machinery, aiming at overcoming the problems of the prior art that the working efficiency of workers and the body health of people are affected. The silencer comprises a silencer air inlet pipe, a silencer shell, a No.1 micro-perforated panel, a micro-perforated pipe, an expansion chamber clapboard, a No.2 micro-perforated panel and a silencer exhaust pipe. The No.1 micro-perforated panel is arranged on the left side in the silencer shell and is welded with the inner wall of the silencer shell, the expansion chamber clapboard is arranged on the right side of the No.1 micro-perforated panel and is welded with the inner wall of the silencer shell, the No.2 micro-perforated panel is arranged on the right side of the expansion chamber clapboard and is welded with the inner wall of the silencer shell, the silencer air inlet pipe is arranged in a front center through hole of the silencer front end cover in the silencer shell, the right end of the silencer air inlet pipe is welded with the center part of the No.1 micro-perforated panel, two ends of the micro-perforated pipe and the No.1 micro-perforated panel are welded width the expansion chamber clapboard, and the silencer exhaust pipe is arranged and welded in a rear center through hole of the silencer rear end cover.

Description

technical field [0001] The invention relates to a muffler in the field of agricultural machinery, more precisely, the invention relates to a muffler for a diesel engine of a high-power agricultural machinery. Background technique [0002] The muffler is a noise reduction device widely used in the exhaust system of internal combustion engines of construction machinery. It is widely used in construction machinery and other fields. In particular, most of the power used in agricultural machinery uses diesel engines, and due to the particularity of agricultural machinery processing objects, and The harshness of the working environment, the noise generated by the diesel engine used in agricultural machinery is very harmful to the driver and the surrounding people. The main performance is as follows: [0003] First, it affects the work efficiency of staff. Noise is easy to cause fatigue, irritability, depression, inattention, etc., which reduces work efficiency and even leads to ...
