Abstract
Provided is a construction machine including an air cleaner and allowing the air cleaner to be easily installed with no enlargement of an installed space while surely avoiding the interference with other structure. The construction machine includes: an air cleaner; a pipe connected to an exhaust port of the air cleaner; a seat plate on which the air cleaner and the pipe are mounted to form a subassembly; and a device including an upper surface on which the subassembly is mounted to form a device-assembly. The subassembly is allowed to be displaced between a first position apart from a first structure and a second position close to the first structure and apart from a second structure and to be fixed at each of the positions.
Claims7
A construction machine comprising:
- an engine;
- an air cleaner having an exhaust port and configured to filter air taken in by the engine;
- a pipe connected to the exhaust port of the air cleaner, the pipe including a fitting seat;
- a seat plate provided as a single plate member on which the air cleaner and the pipe are mounted to form a subassembly;
- a device including an upper surface on which the subassembly is mounted, the device being configured to form, in cooperation with the installed subassembly, a device-assembly to be installed in a predetermined installation space;
- a fixing member for fixing the subassembly to the device, wherein:
- the seat plate comprises a single upper surface, the single upper surface including an air cleaner mounting portion and a pipe mounting portion, the air cleaner being fastened to the air-cleaner mounting portion, the fitting seat of the air-cleaner-side pipe being fastened to the pipe mounting portion;
- one of the seat plate and the surface of the device is provided with an aperture extending in a specific length direction and the other of the seat plate and the surface of the device is provided with a fit-in portion to be fitted into the aperture so as to be capable of relative displacement to the aperture in the length direction;
- the length direction is such a direction that the relative displacement of the fit-in portion to the aperture in the length direction allows the subassembly to be displaced between a first position and a second position, the first position being farther from a first structure, which is an obstacle to the installation of the subassembly into the installation space, and being closer to a second structure other than the first structure, than the second position;
- and
- the fixing member has both of a first fixing mode of fixing the subassembly to the device at the first position and a second fixing mode of fixing the subassembly to the device at the second position.

- and
- the fixing member has both of a first fixing mode of fixing the subassembly to the device at the first position and a second fixing mode of fixing the subassembly to the device at the second position,
- the air cleaner has a cylindrical outer peripheral surface and is oriented so that the exhaust port of the air cleaner faces an opposite side to the engine;
- the pipe includes an end portion connected to the exhaust port, a return portion extending from the end portion toward an engine-side, and a downstream-side portion extending from a distal end of the returning portion to the engine side along the air cleaner;
- and
- the air cleaner is mounted on the seat plate so as to locate at least a part of the downstream-side portion in a space between the cylindrical outer peripheral surface of the air cleaner and the upper surface of the seat plate.
