1. A granular material scoop and near-vertical lifting feeder/conveyor, comprising:
a bullnose rotating scoop with a symmetrically disposed conical working face;
a number of symmetrically distributed graters and vents sized and arranged to break loose and force-in granular material laying below in natural deposits, transport containers and cargo holds;
an open-helical screw that provides a rotating force to the bullnose rotating scoop and a material lift-and-elevation to any forced-in granular materials;
a partial cylindrical skirt fastened between a bottom coil at a distal end of the open-helical screw and an upper circular rim of the bullnose rotating scoop, and that provides mechanical support between them, and that further provides an initial material containment of forced-in granular materials; and
an outer stationary cylindrical sheathing in which is disposed a full length of the open-helical screw and from which protrudes the bullnose rotating scoop.
