Claims

[Scope of utility model registration request]

In an excavation equipment in which a rotating part to the proximal end of an excavator is removably connected to a hollow rotating shaft of a reducer that moves up and down on a leader, the inner wall surface forming the hollow part of the hollow rotating shaft of the reducer is vertically attached. Engagement protrusions are arranged in parallel in the direction, and engagement grooves that engage with the engagement protrusions are arranged in parallel on the outer peripheral wall surface of the rotating part for the excavation tool in the vertical direction, so that the excavation tool is installed in the hollow rotating shaft. An excavating device characterized in that a rotating part is inserted and connected from above.
