Abstract: An excavating bucket apparatus pivotally mounts on an articulating arm of a mobile excavating machine. The bucket includes a scoop member that has a frame and defines a top configured for pivotal connection to the excavating machine's articulating arm. Each of the opposed ends of the scoop member can be open to receive and pass through any material dug or scraped by the scoop member, which defines a bottom disposed opposite the top. The bottom of the scoop member can define a generally banana-shaped bottom profile. The frame carries a screening mechanism disposed at the bottom of the scoop member, and the screening mechanism can define at least two stacked screening decks and a generally banana-shaped profile. The screening mechanism can be mechanically vibrated while being isolated mechanically from the scoop member. The frame accommodates different screening mechanisms, which are easily removed and re-installed.
