Claims

[Scope of utility model registration request]

An excavated soil intake chamber is formed at the back of the cutter head, which is pivotally supported by the shield, and is surrounded by a trumpet-shaped partition wall, and a cylindrical casing is provided through the partition wall, and a spiral band body is provided inside the casing. A ribbon screw is arranged to be rotatable, and a cylindrical body rotatably connected to the rear end opening of the cylindrical casing is fitted and fixed to the rear end of the ribbon screw. A shield excavator characterized in that it is connected to a rotational drive mechanism on the outside.
