Abstract: A construction machine is capable of reducing a decrease in work efficiency due to maintenance for capturing dust. The construction machine includes: an engine; a heat exchanger; a cooling fan that sucks air into an engine chamber to pass the air through the heat exchanger; an intake chamber independent of the engine chamber; an intake tube connected to the intake chamber; and a dust receiving part. The intake tube has a curved part, which has an outside inner wall surface allowing dust in the air to contact it. The dust receiving part is located downstream of the outside inner wall surface to be capable of receiving dust.

Abstract: Provided is a construction machine capable of collecting foreign matter into a dust collection pocket and preventing the foreign matter from being scattered. The construction machine includes a cooler, an air passage forming member including a curved section, a dust-proof filter, a cooling fan generating a normal wind for cooling and a reverse wind opposite thereto, a dust collection pocket, and a turning member. The dust collection pocket has an opening and collects foreign matter at a position downstream of the inner wall surface of the outer corner of the curved section. The turning member is turned about a turning axis by the normal wind and the reverse wind, thereby being moved between a close position to close the opening and an open position to open the opening.
