Engine air intake device and construction machine incorporated with the same

An engine air intake device for use in a construction machine for supplying air to an engine, the air intake device comprising:

• a plurality of air cleaners each including an air inlet for drawing in air, a cleaner main body for filtering the drawn-in air through the air inlet, and an air outlet for drawing out the air filtered through the cleaner main body;
• a merging chamber connected to the air outlets of the air cleaners, and for merging the airs drawn out through the air outlets of the air cleaners to supply the merged air to the engine;
• and
• an air intake duct connected to the air inlets of the air cleaners and for drawing in external air, wherein
• the air cleaners are disposed on a horizontal plane in a state that the air inlets of the air cleaners are directed in a same direction as each other out of an upward direction and a downward direction, and that axial directions of the air cleaners are aligned in parallel to each other,
• the air intake duct is disposed to overlap the air cleaners in the upward direction or the downward direction, in which the air inlets of the air cleaners are directed, and
• the merging chamber is disposed along a direction orthogonal to the axial directions.
