ABSTRACT:
A sawdust-removing device for a band saw machine with a power outlet device is fitted around the shaft of a motor of a band saw machine. The motor can also supply the sawdust-removing device with power at the same time to carry out clearing off sawdust. The sawdust-removing device includes a housing, a rotor and a plurality of blades. The housing has an air chamber for the rotor with the blades to be eccentrically positioned therein. The rotor is rotated by the shaft of the motor to suck in and exhaust out air for blowing off sawdust on planks being sawed. The device is easy to be integrally assembled, takes little space inside the band saw machine and is able to reduce cost in equipment and maintenance.
