Mobile aggregate material processing plant
DC CAFCFirst Claim
1. A mobile, road-hauled aggregate material processing plant comprising:
- a wheel mounted chassis extending in a longitudinal direction;
a plant support frame mounted on the chassis;
a raw material input hopper mounted on the plant support frame;
a material processing means mounted on the plant support frame and fed from the input hopper and having an outlet;
processed material outfeed delivery means mounted on the plant support frame and fed from the material processing means;
at least one lateral delivery conveyor incorporated in the outfeed delivery means, said conveyor comprising;
a conveyor frame tail section;
a conveyor frame head section;
a tail articulation means connecting the tail section to the support frame in such a way that at least part of the tail section is movable relative to the plant support frame from an operative position extending laterally of the chassis with respect to the longitudinal direction for outfeed of processed material, to a transport position extending substantially upright above the chassis and positioned with respect to the input hopper and material processing means so that it does not project laterally beyond the chassis;
a head articulation means connecting the head section to the tail section in such a way that the head section is movable from an operative position to a transport position with the head section extending longitudinally above the chassis and positioned with respect to the input hopper and material processing means so that it does not project laterally beyond the chassis;
a plurality of rollers mounted on the conveyor frame; and
an endless conveyor belt mounted on the rollers to complete the assembly of a lateral delivery conveyor having tail and head sections, said belt defining a conveyor plane.

Abstract
An aggregate material processing plant (1) has an input hopper (5) communicating with a screen box (8) which provides three material separations. The finest material is delivered through a longitudinal conveyor (11). The two other grades are delivered to hoppers (12) (13) which feed lateral conveyors (20). Each lateral conveyor (20) has a head section (22) which pivots relative to a tail section (21) about an axis which is perpendicular to the plane of the conveyor belt (27). In addition, part of the tail section (21) pivots about an axis which extends longitudinally so that whole conveyor can be mounted in the transport position within the lateral confines of the chassis and the height of other parts of the plant.

12. A mobile, road-hauled aggregate material processing plant comprising:
-
a wheel mounted chassis extending in a longitudinal direction; a plant support frame mounted on the chassis; a power plant mounted on the chassis; a raw material input hopper mounted on the plant support frame; a material processing means mounted on the plant support frame and fed from the input hopper and having an outlet; processed material outfeed delivery means mounted on the plant support frame and fed from the material processing output means; at least one lateral delivery conveyor incorporated in the outfeed delivery means, said conveyor comprising; a conveyor frame tail section; a conveyor frame head section; tail articulation means comprising; a pivot joint in the tail section; and driving means connected to the power plant and comprising means for moving at least part of the tail section between a combined material outfeed and maintenance position extending laterally with respect to the longitudinal direction, and a tail section transport position with at least part of the tail section extending substantially upright above the chassis and positioned with respect to the input hopper and the material processing means so that it does not project laterally beyond the chassis; a head articulation means comprising; a pivot joint connecting the tail and head sections; and driving means connected to the power plant and comprising means for moving the head section between an operative position and a position substantially perpendicular to the tail section to provide a maintenance position with the tail section extending laterally and to provide a transport position with the tail section at the tail section transport position; a plurality of rollers mounted on the conveyor frame; and an endless conveyor belt mounted on the rollers to complete the assembly of a lateral delivery conveyor having tail and head sections, said belt defining a conveyor plane.
