ABSTRACT:
A reclaimer apparatus is positioned in an elongated bulk material containing hopper or cargo hold of the type having opposed side walls which slope downwardly and inwardly toward the hopper bottom, the latter having a series of longitudinally extending discharge openings therein for discharging the bulk material on to a conveyor running lengthwise of the hopper. The reclaimer apparatus includes a rigid frame adapted to be located above the discharge openings and means for propelling the frame along the hopper bottom. The reclaimer has cutters thereon adapted to cut through bulk material, such as coal, in planes lying generally parallel to and adjacent the sloping side walls whereby to undercut the bulk mateial and to cause same to cascade downwardly and along the side walls and through the discharge openings.
