Abstract
Achieved are reduction of noise which is caused by air intake sound of a pre-cleaner, improvement of rear viewability and rear visibility of an operator, and extension of a maintenance interval of the pre-cleaner. A wheel loader (1) includes: an engine (18); a hood (23) that covers, in an openable and closable manner, a space in which the engine (18) is contained and that has an air intake opening (23a) through which air is taken into the space; an air cleaner (33) that is contained in the space and that is connected to the engine (18) via a first air intake pipe (34); and a pre-cleaner (31) that is contained in the space and that is connected to the air cleaner (33) via a second air intake pipe (32).
Claims6
A work machine comprising:
- an engine;
- a hood that covers, in an openable and closable manner, a space in which the engine is contained and that has an air intake opening through which air is taken into the space;
- an air cleaner that is contained in the space and that is connected to the engine via a first air intake pipe;
- and
- a pre-cleaner that is contained in the space and that is connected to the air cleaner via a second air intake pipe,
- wherein the pre-cleaner is installed such that a suction port of the pre-cleaner faces away from a side of the hood in which the air intake opening is located.
A work machine comprising:
- an engine;
- a hood that covers, in an openable and closable manner, a space in which the engine is contained and that has an air intake opening through which air is taken into the space;
- an air cleaner that is contained in the space and that is connected to the engine via a first air intake pipe;
- a partition part that partitions the space covered by the hood, into a first space in which the engine is provided and a second space which communicates with outside via the air intake opening;
- a pre-cleaner that is contained in the second space and that is connected to the air cleaner via a second air intake pipe;
- a cooling device provided in the second space;
- and
- a shroud between the cooling device and the engine,
- the partition part including, above the shroud, a partition structure which partitions the first space and the second space from each other, and
- the pre-cleaner being fixed to the partition structure.
