摘要:
A wheel loader (1) comprises an engine (18), a selective catalyst reduction device (23), an injection device (24), an engine room (9), a vehicle body cover (40), a first partition plate (31), a urea aqueous solution tank (13), a urea aqueous solution pump (14), and urea aqueous solution pipe (25). The injection device (24) injects a urea aqueous solution into the exhaust gas fed from the engine (18) toward the selective catalyst reduction device (23). The engine room (9) accommodates the engine (18), the selective catalyst reduction device (23), and the injection device (24). The vehicle body cover (40) defines the engine room (9). The first partition plate (31) has a base plate (31 a) disposed between the selective catalyst reduction device (23) and the vehicle body cover (40). The urea aqueous solution tank (13) is disposed outside of the engine room (9). The urea aqueous solution pipe (25) connects the urea aqueous solution pump (14) and the injection device (24), and extends between the vehicle body cover (40) and the first partition plate (31) inside the engine room (9).

摘要:
An apparatus for opening and closing an engine hood for a construction machine is disclosed that can open an engine hood, which is mounted on an engine room of a small excavator or the like to be opened and closed by a gas spring so that an operator opens the engine hood during checking and repairing various kinds of components in the engine room, at an angle desired by an operator. The apparatus for opening and closing an engine hood includes a frame having one side fixed to an upper swing structure and the other side fixed to a cowl frame, a guide rail having a guide groove formed in a length direction and a plurality of seat portions formed to be cut so as to communicate in a downward direction with respect to the guide groove and maintaining an opening angle that is set to open the engine hood in multiple stages, and a stay rod having a free end slidably formed along the guide rail and a fixed end rotatably fixed to the engine hood.

The present invention provides a machine main body in which the work of moving a supporting member for supporting a lid member with respect to a machine housing section can be easily performed, and an operating machine provided with the machine main body. A first panel 23 includes an engaging section 45 configured to engage with an engaged section 42 so as to allow displacement of the engaged section 42 according to swinging of a hood 30 between a closed position and an open position and restrict the swinging of the hood 30 in a state where an opening section 21 is opened. The engaging section 45 engages with the engaged section 42 such that the engaged section 42 is detachable by being displaced in a predetermined first direction. The machine main body 2 further includes an auxiliary supporting section 50 provided in a machine room S1 and configured to restrict, by detachably supporting the engaged section 42 detached from the engaging section 45, the swinging of the hood 30 in a state where the opening section 21 is opened.

A construction machine includes: a lower propelling body; and an upper slewing body which is slewably mounted on the lower propelling body. The upper slewing body includes: an engine room provided with an intake opening for introducing cooling air from an outside and a discharge opening for discharging cooled air to the outside; a duct provided in the engine room so as to communicate with the discharge opening and adapted to discharge the cooled air to the outside of the engine room from the discharge opening; and an exhaust gas pipe which guides exhaust gas discharged from the engine into the duct. The discharge opening and an outlet of the duct are open downward from the engine room. A portion on a distal end side of the exhaust gas pipe is inserted into the duct. The duct and the exhaust gas pipe are configured to cause the exhaust gas to be mixed with the cooled air in the duct and cause the mixture of the exhaust gas and the cooled air to be discharged downward from the discharge opening.

An illumination device (50) is installed in a box body (31) of a toolbox (30) of a construction machine (10), and is protected by a protective cover (51). Water that flows into the box body (31) through a weep hole (49a) formed in a lid (40) is received by the protective cover (51) and is guided to a water drain hole (32c) formed in a bottom plate (32) of the box body (31). Then, the water is drained to the outside of the box body (31).
