ABSTRACT:
Bulk solids are reclaimed from a large bulk-solids storage pile standing on the ground by a system having a row of arches extending underneath the pile and having feet standing on the ground. An elongated downwardly concave roof is supported on this row of arches and has horizontally spaced lower edges spaced above the ground. A pair of longitudinally extending and parallel tables are supported on the arches below the lower edges of the roof and each have an outer edge turned away from the other table and an inner edge defining with the inner edge of the other table a horizontally extending slot so that bulk solids can flow under the lower edges onto the tables. A carriage is displaceable longitudinally along the row of arches above the slot and under the roof and carries an impeller which is displaceable across the tables and across the slot so that it can sweep material on the tables into the slot. A longitudinally extending conveyor underneath and parallel to the slot is operated to carry away bulk solids swept by the impeller into the slot and falling onto the conveyor. Sidewalls mounted on the outsides of the arches flank this conveyor and are joined at their upper edges to the tables to form a service passage underneath the row of arches.
