<p>A dispensing bin (1) for aggregate and like material includes a scoop (3) extending longitudinally in the bin for rotation about an axis parallel to the longitudinal axis of the scoop so that it describes a cylindrical path in the bin. The scoop (3) is formed by two blades (5) which converge away from the mouth (4) of the scoop to define an open narrow end. The scoop (3) is oscillated about its axis of rotation so that it moves in one direction through a lower part of the bin (1) to pick up material, and then moves in the opposite direction to carry the material to an upper part of the bin where its contents are ejected onto a discharge conveyor (11, 12) by the entry of an appropriately positioned discharge device (15) into the narrow end of the scoop.</p> |
