PURPOSE:To take out and discharge easily dusts such as cutting wastage and the like sucked into a dust collector by compressively depositing dust, refuse and the like in a pressing space with an extrusion screw and providing a discharging section to discharge said dusts out. CONSTITUTION:A screw case 13 is laid and fixed in a dust collecting case 1, and a pressing space 25 is provided at the end of an extrusion screw 3. An opening 25a of the pressing space 25 is closed by a dust cover 27. Dusts are compressed in the pressing space 25 by the extrusion screw 3 and pushed out into a dust guide 26 by said compressing pressure. A bag 28 or the like is attached to the dust guide 26 beforehand to receive dusts discharged and dropped in. At that time, air is discharged out of the opening 25a, and only compressed dusts are received into the bag 28.
