Excavating machinery with bucket for screening and/or mixing excavated material

摘要

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.

主权项

1. An excavating bucket apparatus that is pivotally mountable on an articulating arm of a mobile vehicle and configurable for controlled, powered operation, the bucket apparatus comprising:
a. a scoop member including a frame carrying a first side panel and a second side panel spaced apart and opposed to the first side panel, the scoop member defining a top configured for pivotal connection to the articulating arm of the mobile vehicle, the scoop member defining a forward end and a backward end disposed opposite the forward end, each of the forward end and the backward end extending transversely between the side panels at each of the respective opposite ends of the side panels, the scoop member defining a bottom disposed generally opposite the top; and b. a screening mechanism carried by the frame and disposed generally at the bottom of the scoop member, the screening mechanism defining a bottom deck and a top deck disposed between the bottom deck and the top of the scoop member, the top deck being configured to block passage of material larger than a first predetermined size, the bottom deck being configured to block passage of material larger than a second predetermined size, wherein the first predetermined size is larger than the second predetermined size.
