PURPOSE: A circular cutter device for road repairing construction is provided to make deep and narrow cut on, and selectively use by accepting circular cutters of different diameter to the circular cutter device. CONSTITUTION: A circular cutter device for road repairing construction comprises a plurality of cutters(10,20,30), an upper and lower frames, a support, a rotation driving device, a cutter coupling device, a cutter pressing device, a cutter lifting device, and a supporting device. The upper and lower frames and the support move and support the cutters at a certain location. The rotation driving device allows the cutter to rotate. The cutter coupling device allows one cutter to rotate independently, or the other cutters to rotate together. The cutter pressing device applies the force to the cutter for cutting the road surface. The cutter lifting device allows one of the cutters to lift in order to selectively position to the lowermost. The supporting device allows the upper and lower frames to be supported and fixed at a certain location. |
