シールド掘進機。 In a shield excavator in which a cutter head is rotatably supported relative to the shield body by a plurality of support beams and cutter bearings connected to the cutter head, and a disk-shaped bulkhead is provided at the rear of the cutter head, the cutter head is placed coaxially with the rotation center of the cutter head. A stirring blade is provided to stir the excavated soil inside the chamber surrounded by the back surface of the central part of the cutter head, the support beam, and the disk-shaped partition, and the shaft of this stirring blade is passed through the disk-shaped partition to the side of the shield body. The shaft of the stirring blade is connected via a gear to an independent drive device, and the tip of the shaft of the stirring blade on the face side is rotatably inserted into the center of the cutter head. A communicating hole is provided, and this hole is connected to hydraulic piping for operating the attached equipment such as the slit opening/closing device built into the cutter head and the over-digging device, as well as electrical wiring for transmitting signals from the sensor that detects the ground condition. A shield excavator characterized by having a conductive path.
