Claims

[Scope of utility model registration request]

A rotary cutter for excavation is provided inside the drag head body, and the cutter is removably mounted on a spindle at both ends of the rotor, and a number of donut-shaped support plates are removably fitted to the rotor. The rotor is composed of a large number of blades attached to the outer periphery of the support plate via holders, and spacers arranged between the support plates, and the rotor is connected to the flanges of the support shafts at both ends. A pair of rotor end portions each having an inner periphery flange removably connected to the rotor end portion, and a rotor center portion disposed between these rotor end portions, the rotor center portion being connected to the rotor end. A drag head device with a cutter, characterized in that the drag head device is fixed to an outer peripheral flange of the cutter via the support plate that is detachably connected to the outer peripheral flange of the cutter.
