Abstract
A conveyor assembly comprising a main inclined conveyor with a screen box located at a discharge or off-loading end thereof, the main conveyor and screen box being located on an elongate structure including length adjustable legs intermediate its ends mounted on wheels. The loading end of the screen box is pivoted on an axis transversely of and at the discharge end of the structure with the screen box extending towards the loading end of the structure, the discharge end of the screen box being connected to the structure by length-adjustable legs thereby to alter the inclination of the box. A cradle is suspended below the structure to carry one or more boom conveyors the or each to receive a grade of material, the cradle being horizontally oriented and connected by linkage with the structure and the box whereby pivotal movement of the box causes synchronous movement of the cradle such as to maintain a horizontal orientation of the cradle.
