US 10,851,698 B2 · Exhaust gas guiding device for a construction machine

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 the exhaust 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 to the 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 central axis away from a central axis of the exhaust cover.

Dependent claims

An exhaust gas guiding device for a construction machine, the exhaust gas guiding device comprising:

an exhaust passageway formed at a bonnet of the construction machine to connect an interior and an exterior of an engine room in the construction machine with each other;
a straight exhaust pipe connected to the exhaust passageway to discharge an exhaust gas in the engine room to the exterior of the construction machine;
and
an exhaust cover arranged at the exhaust passageway and protruded from the bonnet to guide the exhaust gas in the straight exhaust pipe to the exterior of the construction machine,
wherein the exhaust cover comprises a straight cylindrical cover body connected with the exhaust passageway, and an exhaust portion slantly connected to an upper end of the straight cover body to guide the exhaust gas in an extending direction of the exhaust cover, and
wherein the straight exhaust pipe is arranged adjacent to an inner surface in the straight cover body to have a central axis offset from a central axis of the straight cover body.

An exhaust gas guiding device for a construction machine, the exhaust gas guiding device comprising:

an exhaust pipe connected to an exhaust passageway, which is formed at a bonnet of the construction machine, to discharge an exhaust gas of an engine to an exterior of the construction machine;
and
at least one counter flow-preventing member arranged on an inner surface of the exhaust pipe to interfere with the exhaust gas discharged from the exhaust pipe, thereby preventing a counter flow of the exhaust gas,
wherein
the at least one counter flow-preventing member has a plate shape horizontally protruded from the inner surface of the exhaust pipe,
the at least one plate-shaped counter flow-preventing member has a first length measured along an axial direction of the exhaust pipe, and a second length measured along a radius direction of the exhaust pipe,
the first length is shorter than the second length, and
the at least one counter flow-preventing member protrudes orthogonal to a central axis of the exhaust pipe.
