ABSTRACT:
A pair of screw conveyors pivotally mounted on rotatable arms extending laterally from the extended ends of the bottom sprocket wheel shaft on a bucket ladder dislodge bulk material and direct it toward the buckets. The bottom sprocket wheels are journaled for rotation independent of the shaft which is rotated by a centrally located drive mechanism to position the rotatable arms and therefore the screw conveyors for various operations.
