Abstract
A bucket wheel type excavator is provided in which a vibrating movement is imparted to the individual cutting components of each bucket on the wheel. Moreover, each such imparting movement to the individual teeth or cutting components is from a single excitation device fixed in the axis of the wheel and driven from a power source coaxially through a hollow shaft for the wheel. The imparting movement is through flexible bars extending from the excitation device to a point adjacent the cutting components wherein the vibrating end of the respective flexible bar is spaced from and intermittently vibrates the cutting component which, in turn, is pivotally mounted.
