US Patent 10457486 Double portable drive-over hopper

An apparatus includes a first transverse conveyor, first and second pairs of foldable parallel ramps, and first and second foldable longitudinal conveyors. The transverse conveyor moves material in a first direction. The first pair of foldable parallel ramps extend from a first side of the transverse conveyor. The first foldable longitudinal conveyor is positioned between the ramps of the first pair, and is configured to move material toward the transverse conveyor in a second orthogonal direction. The second pair of foldable parallel ramps extend from a second side of the transverse conveyor and are in alignment with the ramps of the first pair. The second foldable longitudinal conveyor is positioned between the ramps of the second pair and is configured to move material in a third direction that is substantially opposite the second direction.
