Conveying means for removing a heap of debris

Apparatus for removing and conveying a heap of debris comprising:

• a frame;
• a continuous conveyor supported by the frame, the conveyor having a charging end and a discharging end;
• two longitudinally extending, transversely spaced-apart cantilever arms having outer free ends and having inner ends pivotally supported on said frame for swinging movement about a horizontal transverse arm pivot axis between lowered and raised positions;
• a transverse crossbeam extending between the outer free ends of said arms and pivoted thereto from swinging movement about a horinztonal beam axis;
• a loading shovel having an open front for shoveling up debris and a back wall which has an upper edge;
• means pivoting said shovel to said crossbeam for swinging movement about a horizontal shovel pivot axis which is located near said upper edge of said back wall, the arrangement of shovel, crossbeam and arms being such that in the lowered position of said arms, said shovel pivot axis is above said beam axis and said shovel is swingable to a lowered, loading position in engagement with said beam for shoveling in debris and such that in the raised position of said arms said shovel is swingable to a raised position in which said upper edge of said back wall forms a discharge edge for discharging shoveled material to the charging end of the conveyor;
• means supported on at least one of said arms and acting on said crossbeam for swinging same about said beam pivot axis;
• means supported on said crossbeam for swinging said shovel about said shovel pivot axis;
• and means for swinging said arms about said arm pivot axis.
