Noise elimination and reduction device of diesel engine

Abstract

The invention discloses a noise elimination and reduction device of a diesel engine. The noise elimination and reduction device comprises a lower base, an upper base, fixed holes, fixed rods, an extrusion assembly, a cooling assembly, a lifting assembly and a fixed plate, wherein the fixed rods are fixedly welded to the periphery of the top of the lower base; the fixed holes are formed in the periphery of the top of the upper base, and the fixed holes penetrate to the bottom of the upper base; the upper base sleeves the fixed rods through the fixed holes; the upper base is provided with the extrusion assembly; and one side of the lower base is provided with the fixed plate. According to the noise elimination and reduction device, the diesel engine can be convenient to extrude and fix, andthe distance between an extrusion plate a and an extrusion plate b is adjusted conveniently, so that the extrusion tightness is adjusted, the vibration amplitude of the diesel engine is reduced, the stability is improved, and the noise reduction and elimination are achieved conveniently; the temperature of an exhaust pipe can be reduced, and the impact force between molecules is reduced, so that the noise reduction and elimination are achieved conveniently; and the height of a semicircular storage plate can be adjusted conveniently, and the exhaust pipe can be placed conveniently.

Description

technical field [0001] The invention relates to the field of diesel engine noise reduction equipment, in particular to a diesel engine noise reduction device. Background technique [0002] A diesel engine is an engine that burns diesel for energy release. It was invented by German inventor Rudolf Diesel (Rudolf Diesel) in 1892. To commemorate the inventor, diesel is represented by his surname Diesel, and the diesel engine is also called Diesel engine ( Diesel engine). Diesel engines are widely used and are at the core of the industrial chain. In the past ten years of development, the diesel engine production industry has formed a series of supporting enterprises, and many diesel engine enterprises have played the role of general contractor and assembler. Some key parts of diesel engines: crank connecting rod , Pistons, cylinder liners, and cams have been handed over to professional companies for production. Specialized division of labor enables diesel engine manufacturer...

Problems solved by technology

[0003] For the use of agricultural machinery, diesel engines are often used as power. When the diesel engine is working, it will produce a lot of noise. Generally, the noise reduction device is used to reduce the noise of the diesel engine. However, there is an existing noise reduction device for diesel engines. The following defects: It is not conducive to squeezing and fixing the diesel engine, the tightness of the clamping is not easy to adjust, and it is not conducive to reducin
