Abstract

The application discloses a cutter device of a cutter suction dredger, which comprises a driving shaft, one end of the driving shaft is connected with a driving motor, the bottom end of the driving shaft is connected with a connecting cylinder, the top end of the connecting cylinder is connected with a discharging pipe, the bottom end of the connecting cylinder is connected with a bottom plate, and the bottom end of the bottom plate is provided with an inlet hole; when the driving motor drives the driving shaft to move, the driving shaft drives the connecting cylinder to move, the connecting cylinder drives the bottom plate to move, the bottom plate drives the reamer blade to drill and dig, and the silt will be moved to the inlet hole into the connecting cylinder in cooperation with the starting of a silt pump, and then the silt is discharged into a collecting box through the discharging pipe; when the silt is blocked around the bottom plate, a power mechanism is started, the power mechanism drives an agitating mechanism and a pushing mechanism, the agitating mechanism stirs away the silt outside the bottom plate, and the pushing mechanism pushes out the blocked stones or silt in the inlet hole, so that the stable silt suction of the inlet hole is ensured.
