1. A mobile feeder loader comprising:

  • a mobile base for entirely supporting said mobile feeder loader having support assemblies that facilitate moving the mobile feeder loader between locations;

    a feed station mounted on said base which is elevatable to a position for movement between locations and lowerable to a stationary ground position to have material pushed thereon by a bulldozer-type vehicle;

    a single straight inclined conveyor having a lower end and an upper end for receiving material from said feed station at said lower end and conveying the material upward until the material falls off of the upper end;

    said feed station having a feed discharge located above said lower end of said conveyor for discharging materials from said feed station onto said lower end of said conveyor;

    said conveyor having spaced apart sidewalls with a bottom edge on each side of said conveyor to define a trough with a lower entrance end and an upper discharge end;

    said conveyor including an endless path of conveyor chain links running from said conveyor lower end to said conveyor upper end;

    an endless rigid conveyor surface comprising overlapping rigid flights each fastened to said chain links to be carried therewith and secured against pivotal movement with respect to said chain links, said flights located between and under the bottom edge of said sidewalls, said flights being sufficiently rigid to carry large heavy materials and non-porous to prohibit material carried thereon to pass through said flights, said overlapping flights each having a forward edge, a rearward edge, and a substantially planar upper surface therebetween, said forward edge of one flight overlapping and protruding above said upper surface of an adjacent flight to provide an exposed abutment surface for assisting the movement of material along the conveyor; and

    a motor for driving said endless path of chain links.
