Cutting device

Abstract

To provide an efficient cutting device for plane cutting that is equipped with a pair of cutting drums, avoids generation of cutting residue without using a complicated mechanism and does not waste energy.SOLUTION: A cutting device 1 includes a single motor 50 that has an output shaft 51, a drive shaft 60 that is disposed in the direction perpendicular to the axis of the output shaft 51 and connected to the output shaft 51 via a gear member 61, two rotating shafts 70 each connected via a joint member 71 at both ends of the drive shaft 60 and a pair of truncated conical cutting drums 80 each fixed to the rotating shaft 70. Each of the rotating shafts 70 is connected to the drive shaft 60 at a predetermined angle θ so that cutting surfaces 83 of the pair of cutting drums 80 are horizontal.SELECTED DRAWING: Figure 3
