ABSTRACT:
A raker boom supports a plurality of independently driven and mounted rotatable raker wheels which are applied to the face of a pile of material to dislodge and move the material downwardly toward a bucket wheel and conveyor for gathering and conveying the material to a remote location for processing. The boom is capable of rotating in a vertical plane so that the raker wheels can contact and remove all of the material through the depth of a pile. By operating the raker wheels individually and mounting them independently, the raker apparatus can travel and apply the individual raker wheels over the surface of a pile of material regardless of its contour. The wheels can break up lumps of material, especially on the surface of the pile, and mix the material with other material within the pile. In one configuration of the preferred embodiment, a pair of opposed raker wheel booms are mounted on a raker carriage which itself is mounted for reciprocal travel on a raker truss. The whole raker truss then travels over the area of the base of the pile of material at right angles to the direction of reciprocating movement of the raker carriage. In another configuration of the preferred embodiment, the raker truss rotates about the center of a pile of material. The truss can be designed to rotate in only one direction, so only one raker wheel boom is needed.
