Muffler waterproof exhaust structure

Abstract

The invention discloses a muffler waterproof exhaust structure. The muffler waterproof exhaust structure comprises a muffler, a muffler exhaust inner tube, a reinforcing sleeve and an exhaust tail pipe; one end of the muffler exhaust inner tube is in communication with the muffler, the reinforcing sleeve sleeves one end of the muffler exhaust inner tube, the lower end of the reinforcing sleeve isfixedly connected with the muffler, the upper end of the reinforcing sleeve is lower than the other end of the muffler exhaust inner tube, the exhaust tail pipe sleeves the other end of the muffler exhaust inner tube, and is thus connected with the reinforcing sleeve in a sleeved mode, and a drainage gap is formed between the exhaust tail pipe and the muffler exhaust inner tube above the reinforcing sleeve; and the exhaust tail pipe is provided with a plurality of drainage holes in a drainage gap section. The muffler waterproof exhaust structure avoids the problems such as rainwater flows intothe inner part of a muffler along a muffler exhaust port, parts are eroded, engine oil is diluted, an engine is damaged, and solves the problem of tearing of the muffler caused by the exhaust tail pipe when a whole vehicle shakes.

Description

technical field [0001] The invention relates to the field of engines, in particular to a waterproof exhaust structure for a muffler. Background technique [0002] The engine exhaust gas outlet of construction machinery and agricultural machinery usually goes upwards, and the exhaust gas outlet section (that is, the exhaust tail pipe) is mostly made into a curved curved shape with chamfered edges. Rainwater poured into the exhaust tailpipes. The other is to add a rain cover to the exhaust tailpipe. [0003] The two kinds of rainproof structures commonly used above, among them, the arc-shaped structure is directly set on the exhaust outlet of the muffler, and the exhaust tailpipe is directly in close contact with the exhaust outlet of the muffler. When the wind blows and it rains, the rainwater will flow into the muffler body along the inner wall of the exhaust tailpipe, and in severe cases, it will cause accumulated water to flow from the muffler to the inside of the engine...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a muffler waterproof exhaust structure with a simple and reasonable structure, which avoids rainwater flowing into the muffler along the exhaust port of the muffler, eroding components, diluting engine oil, and damaging the engine. Solved the problem of tearing the muffler caused by the exhaust tailpipe when the vehicle shakes
