Mounting structure of muffler outer hood of snow remover

Abstract

The invention relates to a mounting structure of a muffler outer hood of a snow remover, which comprises an inner hood, an outer hood, an air filter, a cylinder end and a muffler. The mounting structure is characterized in that the inner hood and a bracket at the top part of the muffler are connected by a bolt; the outer hood is arranged at the outside of the inner hood; one end of the outer hood is welded with one end of the outer hood of the muffler; the other end of the outer hood is connected with the shell of the air filter by a bolt; the cylinder end is fixed in the shell of the air filter, a protective hood and the inner hood by bolts. The adopted technical proposal leads the outer hood and the inner hood not to be contacted, avoids the heat of an engine from being directly transferred to the outer hood of the muffler and has the advantage of safe use.

Description

technical field [0001] The invention relates to a muffler device, in particular to an installation structure of a muffler outer cover of a snowplow. Background technique [0002] Snowplows are widely used in cold areas where it often snows because they can quickly clear the snow on the road surface. And it is the engine that drives the snowplow to plow snow. The muffler is a device that allows airflow to pass through and attenuates noise, and is one of the important parts of the snowplow. The performance of the muffler not only affects the noise of the snowplow, but also has a great influence on the performance of the engine, such as power, fuel consumption, and torque. [0003] The traditional muffler outer cover, the inner cover and the muffler are fixed together by bolts. Due to the heat generated when the engine is working, the inner cover of the muffler becomes a high-temperature component. The inner cover of the muffler transmits high temperature to the outer cover t...

AI Technical Summary

Problems solved by technology

[0003] The traditional muffler outer cover, the inner cover and the muffler are fixed together by bolts. Due to the heat generated when the engine is working, the inner cover of the muffler becomes a high-temperature component. The inner cover of the muffler transmits the high temperature to the outer cover through four studs. The temperature of the muffler cover is high, which is easy to cause safety accidents

In addition, the muffler outer cover and the inner cover and the muffler pass through the bolts, and the studs need to be welded on the muffler. Since the contact area between the muffler and the studs is small, the welding of the muffler and the studs will cause stress concentration and material changes due to welding, which will also affect other parts. The connection strength of the two; in addition, because the contact area between the inner cover and the stud of the muffler is too small, the welding stress area is also small, coupled with the vibration of the engine, the muffler is easily broken at the welding stud, which is likely to cause a safety accident
