Smoke hole structure for the smoke exhaust pipe to pass through, construction machinery

Abstract

The invention discloses a smoke hole structure allowing a smoke exhaust pipe to penetrate and engineering machinery. The smoke hole structure comprises a housing (1) and an adjusting plate (2). An opening (3) is formed in the wall of the housing (1). The adjusting plate (2) is mounted on the housing (1) and covers one part of the opening (3) so as to allow the other part of the opening (3) to form a smoke hole (4) allowing the smoke exhaust pipe to penetrate. The mounting positions of the adjusting plate (2) can be adjusted, so that the positions of the other part, serving as the smoke hole (4), of the opening (3) can be changed, and the smoke hole structure is applicable to the mounting of the smoke exhaust pipes of different types of engines while the strength and rigidity of the housing are unaffected.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a smoke hole structure through which a smoke exhaust pipe of a construction machine passes, and a construction machine with the smoke hole structure. Background technique [0002] When construction machinery such as excavators are operating in the field, due to the construction work requirements and the relatively harsh construction environment, the engine of the construction machinery will often run under heavy load and be affected and eroded by wind, rain, high temperature, severe cold and dust, etc., and it is prone to failure. And when the engine breaks down, if the construction site cannot be ruled out and the same type of engine is not available, in order to ensure the construction progress, it is usually necessary to replace other types of engines. [0003] In the existing installation structure of the engine, a single hole is formed on the casing of the engi...

AI Technical Summary

Problems solved by technology

However, due to the differences in the positions of the exhaust holes of different types of engines, and their different installation structures, a single hole on the casing cannot be used universally for the installation of exhaust pipes of different types of engines.

In addition, if only the single hole is enlarged or other holes are opened on the casing, it will inevitably affect the weakening of the local strength and rigidity of the casing.
