PROBLEM TO BE SOLVED: To provide a multi-spindle excavator which can prevent overall multiple spindles from twisting due to rotation thereof during excavation, and prevents excavating directions from shifting not only horizontally but also vertically, to thereby improve the workability. SOLUTION: According to the structure of the multi-spindle excavator, the plurality of excavating spindles 5 bound together at intermediate locations thereof, by binding bands 9, are connected to a driving mechanism in a downward direction. Ends of the respective binding bands 9 mounted on the excavating spindles at a vertical interval are connected to each other by curved vertical plates 11 arranged on the external sides of the excavating spindles 5 standing on right and left ends, respectively, to thereby set up a frame.
