Problems solved by technology

The exhaust gas ejected through the exhaust pipe is bent by the exhaust hood, and therefore, a stagnation point (stagnation point) may be formed inside the exhaust hood where a part of the exhaust gas cannot flow back toward the outlet of the exhaust hood.
In this way, the exhaust gas flowing backward at the stagnation point may flow backward into the construction machinery, for example, to the engine compartment, causing various problems

Abstract

An exhaust gas guiding device includes an exhaust passageway, an exhaust pipe and an exhaust cover. The exhaust passageway is formed in a bonnet of the construction machine to connect an engine room with an exterior of the construction machine. The exhaust pipe is connected to the exhaust passageway. The exhaust cover is installed at the exhaust passageway to protrude from the bonnet to guide theexhaust gas to the exterior. The exhaust cover having a cylindrical shape connected to the exhaust passageway includes a cover body and an exhaust portion. The exhaust portion is slantly connected tothe cover body to guide the exhaust gas in an extending direction of the exhaust portion. The exhaust pipe is positioned adjacent to an inner surface of the cover body. The exhaust pipe has a centralaxis away from a central axis of the exhaust cover. Therefore, the exhaust can be concentrated to the oblique surface of the discharging part of the exhaust cover later than other positions for beingdischarged, thereby increasing a propelling force of the exhaust.

Description

technical field [0001] The present invention relates to an exhaust gas guide device of a construction machine, and more particularly, to an exhaust pipe for discharging exhaust gas generated in an engine and an exhaust gas guide device including the exhaust pipe. Background technique [0002] Generally, exhaust gas generated in an engine of a construction machine can be discharged through an exhaust pipe. The exhaust pipe may be connected to the engine, and may be connected to an exhaust passage formed in a bonnet connecting the inside and the outside of the construction machine. An exhaust hood can be connected to the exhaust pipe. [0003] According to the related art, the exhaust hood may include a discharge portion that bends a flow direction of exhaust gas discharged through the exhaust pipe toward a direction at an acute angle with respect to a vertical direction of the engine cover. The exhaust gas ejected through the exhaust pipe is deflected by the exhaust hood, a...
