切断カツターにおける集塵装置。 A motor case with a built-in drive motor,
a cutter cover that covers a rotary blade driven by the motor via a gear transmission mechanism; a gear case interposed between the motor case and the cutter cover; and a gear case such that the lower part of the rotary blade protrudes downward from the lower surface. In the electric cutting cutter, the cooling air flow generated by the rotation of the motor cooling fan attached to the shaft of the motor is passed through the intake duct through the air hole of the gear case to cutter. On the other hand, the front part of the cutter cover is designed to prevent dust generated during cutting by the rotary blade and airflow caused by the rotation of the rotary blade from being dispersed. The dust introduced into the upper chamber and allowed to merge with the cooling air flow is separated from the inside of the cutter cover by a partition wall, and the front part of the cutter cover is provided with a lower A dust collection device for an electric cutting cutter, characterized in that a dust collection box is formed with a discharge port that can be freely opened and closed, and is removably attached in communication with the upper chamber and symmetrically to the motor case.
