Patent ID: 8668754

Claim:
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 air cleaner 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, the merging chamber merging the air drawn out through the air outlets of the air cleaners to supply the merged air to the engine; and an air intake duct having a duct main body connected to the air inlets of the air cleaners, the air intake duct drawing in external air, wherein the air cleaners are disposed on a horizontal plane such 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 the air cleaners are further disposed such that axial directions of the air cleaners are aligned in parallel to each other and parallel to the horizontal plane, wherein the air intake duct is disposed above the air inlets of the air cleaners which are directed in the upward direction to overlap the air cleaners from above, or below the air inlets of the air cleaners which are directed in the downward direction to overlap the air cleaners from below, wherein the merging chamber is disposed to longitudinally extend along a direction orthogonal to the axial directions, and wherein the air intake duct is disposed with respect to the air cleaners in such a manner that a lengthwise direction of the duct main body is aligned in parallel to the axial directions of the air cleaners.
