Abstract:
PROBLEM TO BE SOLVED: To provide a dust collection cover to be attached to a cutter used for cutting processing of a concrete block and grooving processing of an asphalt road surface, relating to a dust collection cover comprising a double structure of a fixing cover and a main body cover which are connected so as to mutually open and close and energized to an opening direction by a spring, which is capable of solving conventional problems that the fixing cover and the main body cover cannot be fixed mutually at a certain angle so that working ability is not preferable when a rotary cutter tool is made cut in from an end part of a cut surface to move along the cut surface for performing cutting processing, so that the invention allows cut-in depth of the rotary cutter tool to be fixed, thereby improving the work.SOLUTION: The invention is configured to provide a fixing stopper 60 between a fixing cover 22 and a main body cover 23 for locking mutual rotary motions of both covers 22, 23. Since mutual rotary motions of the covers 22, 23 are locked, a protrusion amount to a lower face side of a base 21 of a rotary cutter tool is fixed.SELECTED DRAWING: Figure 14
