Claims

[Scope of Claim for Utility Model Registration] (1) In an excavator in which a league is erected and supported by a support member protruding from the base machine, and the league guides the vertical movement of the excavation shaft, the excavation shaft is It is formed by a shaft that has a continuous corner on the outer surface over the lower end and can connect a plurality of shafts in sequence, and a bit located at the bottom.1. The league is provided with an excavation shaft rotation drive device that applies rotational force to any part of the shaft of the excavation shaft, and the excavation shaft rotation drive device has a cross-sectional shape that is the same as the outer shape of the shaft and penetrates in the vertical direction. It is characterized by having an endless fitting cylindrical body that is slidably fitted to the shaft in the vertical direction endlessly through a fitting hole, rotatably provided via a bearing, and a motor that rotationally drives this endless fitting cylindrical body. Endless type excavator. (2) The excavation shaft rotation drive device consists of multiple units installed in parallel,
Endless type excavation according to claim 1, characterized in that a plurality of rows of excavation shafts are arranged in parallel in the plurality of excavation shaft rotation drive devices, and each row of excavation shafts is independently rotationally driven. Machine.
