    • Engine noise of a construction machine is effectively reduced without reducing cooling performance and with an increase in the height of a body cover kept minimum. To achieve the above, an air-intake opening portion (10) and an air discharge opening portion (11) are arranged in a body cover (8) of an upper rotating body (1), and a cooling fan (5) in an engine room covered by the body cover (8) is driven, taking cooling air in from the air-intake opening portion (10) to cool a heat exchanger (7) in the body cover (8) and discharging the air from the air discharge opening portion (11). The air-intake opening portion (10) is laterally offset from a position facing to a ventilation surface of the heat exchanger (7). Alternatively, plural air-intake opening portions are located in a scattered manner such that the plural air-intake opening portions include the offset air-intake opening portion offset from the ventilation surface of the heat exchanger (7).
    • 在不降低冷却性能的同时,能够有效地减少施工机械的发动机噪音,并且使车身罩的高度保持最小。 为了实现上述目的,在上部旋转体(1)的主体罩(8)中设置有进气口部(10)和排气口部(11) 由主体罩(8)覆盖的发动机室被驱动,从进气口部分(10)吸入冷却空气以冷却车身盖(8)中的热交换器(7)并从空气排出口排出空气 开口部(11)。 进气口部分(10)从面向热交换器(7)的通风表面的位置横向偏移。 或者,多个进气口部分以分散的方式设置,使得多个进气口部分包括从热交换器(7)的通风表面偏移的偏移进气开口部分。

    • The present invention relates to a silencer easily cleanable inside. This silencer comprises a casing cylinder and a segment member housed in the casing cylinder to constitute a sound reducing means. The silencer further comprises a segment member fastening means for fastening the segment member to the casing cylinder, a gas inlet-side lid plate with a punched hole, which closes an opening at one end of the casing cylinder, and a gas outlet-side lid plate with a punched hole, which closes an opening at the other end of the casing cylinder. At least either one of the gas inlet-side lid plate or the gas outlet-side lid plate is adapted to be detachable from the casing cylinder.
    • 本发明涉及一种可在内部容易清洗的消音器。 该消声器包括套筒和容纳在套筒中的分段件,以构成减声装置。 消音器还包括用于将分段构件紧固到套筒的分段构件紧固装置,具有冲孔的气体入口侧盖板,其封闭在套筒的一端的开口,以及气体出口侧盖 具有冲孔的板,其封闭在套筒的另一端的开口。 气体入口侧盖板或气体出口侧盖板中的至少一个适于从套筒拆卸。

    • A construction machine includes an engine guard, an engine, a cooling fan, and a device for being cooled by the cooling fan, and an exhaust duct. The engine guard accommodates the engine and has intake and exhaust openings. The intake opening and the exhaust opening are disposed in different side covers. The side covers correspond to the left and right side walls of the engine guard. The engine, the cooling fan, and the device are accommodated in the engine guard. The exhaust duct is disposed above and behind the engine, parallel with the flow of a fan air which has been used for cooling the engine, and substantially horizontally. The exhaust duct has an exit connected to the exhaust opening. The fan air introduced from the intake opening flows substantially linearly along the cooling fan, the engine, and the exhaust duct and is discharged from the exhaust opening.
