Abstract
An engine cutter which is simple in structure and low in manufacturing cost. This engine cutter comprises a disk cutter, an air-cooled internal combustion engine for rotating the disk cutter, a safety cover partially encasing the disk cutter, and a dust-trapping portion which is mounted on the safety cover for trapping and discharging dust to be generated from a cutting work by the disk cutter; and is characterized in that only single fan to be driven by the engine is provided not only for generating an air flow for sucking and discharging the dust that has been trapped in the dust-trapping portion but also for generating a cooling air flow for cooling the internal combustion engine.
Claims6
An engine cutter comprising;
- a disk cutter having a cutting portion at the lower end portion thereof;
- an air-cooled internal combustion engine having an output shaft for rotating the disk cutter;
- a safety cover partially encasing the disk cutter;
- a dust-trapping portion mounted on the safety cover adjacent to and rearwardly of the cutting portion of the disk cutter for trapping and discharging dust to be generated from a cutting work by the disk cutter;
- an airflow passageway;
- and
- a fan having a rotation axis driven by the internal combustion engine for generating an air flow in the air flow passageway for sucking and discharging the dust therethrough that has been trapped in the dust-trapping portion and for generating a cooling air flow for cooling the internal combustion engine.
