CONSTRUCTION MACHINE INCLUDING ENGINE

摘要

Provided is a construction machine capable of smooth exhaust and suppression of a leak of noise from an engine room, including an engine guard defining an engine room, a cooling fan disposed in the engine room, a projection element projecting upward beyond the engine guard, and an exhaust duct. The exhaust duct has a bent shape including a first duct section extending along an axial flow direction of the cooling fan from an upstream end portion surrounding a duct inlet to a connection portion and a second duct section extending upward from the connection portion and surrounding a duct outlet opened upward, also including an engine concealment section obstructing a direct view to an engine through the duct outlet from outside the engine room.

主权项

1. A construction machine comprising:
an engine; an engine guard defining an engine room which is a space where the engine is housed; a heat exchanger disposed in the engine room; a cooling fan disposed in the engine room so as to suck air for cooling from outside of the engine room and to make the air pass through the heat exchanger; a projection element that projects upward beyond the engine guard; and an exhaust duct forming a passage for leading the air, which has passed through the heat exchanger, to outside of the engine room, the exhaust duct having a bent shape including a first duct section that includes an upstream end portion surrounding a duct inlet opened in the engine room and a connection portion closer to the projection element than the upstream end portion, the first duct section extending along an axial flow direction of the cooling fan from the upstream end portion to the connection portion, and a second duct section extending upward from the connection portion of the first duct section and surrounding a duct outlet opened upward outside the engine room, the exhaust duct thereby including an engine concealment section that obstructs a direct view to the engine through the duct outlet from outside the engine room.
