ABSTRACT:
In a dry cutting and grooving apparatus for pavement in which blades for cutting or grooving the pavement are covered by a housing which leaves the lower ends of the blades exposed, and in which chips and cutting powder generated at the time of cutting and grooving operation by the blades are collected by a suction means connected to the housing, air is forcibly supplied to the housing and the dust stored within the housing is quickly scavenged by the air flow toward the suction end. Further, by providing an air supply passage within the main shaft of the blades and discharging the air from the surface and the outer periphery of the blades, the dust within the housing is scavenged in the same manner while the tips of the blades can be cooled by the discharged air.
