1. A bucket for earth moving equipment comprising a blade section having a lower leading edge, a collecting section pivotably connected to said blade section for movement about a normally horizontal axis of rotation, said axis of rotation being spaced from said lower leading edge and said collecting section being positioned in front of said blade section and having a leading end and a trailing end, a digging edge at said leading end and a trailing edge at said trailing end, said trading edge being adjacent to and being in close proximity to said leading edge when said bucket is in a closed position and means to pivot said collecting section relative to said blade section around said rotational axis to rotate said collecting section between said closed position and a fully open position with said leading edge and said trailing edge spaced apart characterized in that:

  • an annual separating section is connected to and projects rearwardly from said collecting section, said separating section having an inner surface with a radius measured from said axis of rotation substantially equal to the radial distance between said leading edge of said blade section and said axis of rotation, said separating section being on the side of said leading edge of said blade section remote from said collecting section when said bucket is in closed position, substantially radially exiting holes through said separating section, said separating section forming the bottom of said bucket between said leading and trailing edges when said trailing edge is spaced from said leading edge and said bucket is in a partially open screening position, thereby material may be separated through said holes in said separation section.
