Abstract

PURPOSE: To excavate a groove and a hole in an arbitrary direction by using a bucket by a method wherein a cutter is provided and openings to introduce soil in a cylinder are formed in the side of a cylindrical bucket rotated by a drive device and a bottom cover openably arranged. CONSTITUTION: A bottom cover 34 is mounted in the under surface of a cylindrical bucket body 20 through a hinge 33 and openably operated through rotation of a lock rod 41. A cutter 70 is fixed at the side of the bucket body 20, a center cutter 35 and a cutter 37 are fixed at a bottom cover 34, and soil introduction parts 74 and 36 are arranged at a front part in an excavation rotation direction in the vicinity of the cutter. A drive device 19 is mounted on the bucket body 20, and a hydraulic shovel tip and mounted on the tip of a hydraulic shovel through a bracket 18 for mounting. This constitution uses this device when a groove is excavated in a direction in which this device crosses a narrow road and when a circular hole is excavated for constructing a manhole.
