Abstract

A mobile bulk material processing apparatus includes a main frame to support a material processing unit. A conveyor extends from the main frame and is mounted on a pivot joint to allow the conveyor to slew relative to the main frame, the pivot joint being positioned above the conveyor that is suspended below a region of the main frame.

First claim

The invention claimed is:

1. A mobile bulk material processing apparatus comprising:
a main frame mounted or supported such that a conveyor support region of the main frame is suspended above the ground, wherein the main frame includes a longitudinal axis extending between a first forward end and a second rearward end of the main frame;
a conveyor for transporting material to or from the material processing apparatus, the support region of the main frame including a pair of opposed beams extending in the longitudinal axis direction and spaced apart in a direction perpendicular to the longitudinal axis to accommodate part of the conveyor between the opposed beams when the conveyor is aligned with the longitudinal axis, wherein the conveyor includes a head and tail section pivotally mounted together to allow the head to bend or fold relative to the tail to raise and lower a distal end of the conveyor relative to the support region of the main frame;
a pivot joint coupling the conveyor to the conveyor support region of the main frame such that the conveyor is arranged to pivot to change a position of the distal end of the conveyor relative to the main frame, wherein the pivot joint is positioned above the conveyor to suspend the conveyor below the support region of the main frame; and
a linear coupling mounting the pivot joint at the support region of the main frame, the linear coupling being configured to provide linear movement of the conveyor along the conveyor support region of the main frame, wherein the linear coupling includes at least one track or rail mounted at the main frame, the pivot joint being configured to move along the track or rail.

2. The apparatus as claimed in claim 1 , wherein the linear coupling includes a bracket extending upwardly from the pivot joint and having at least one uppermost end region arranged to contact the track or rail such that the bracket is configured to move along the track or rail.

3. The apparatus as claimed in claim 1 , wherein the conveyor is a discharge conveyor mounted towards the first end to discharge processed material.

4. The apparatus as claimed in claim 3 , wherein the pivot joint moves linearly in a direction of the longitudinal axis towards and away from the first end.

5. The apparatus as claimed in claim 1 , wherein the pivot joint includes a turntable or a slew ring.

6. The apparatus as claimed in claim 1 , wherein an axis of the pivot joint is aligned substantially vertically when the apparatus is mounted or suspended on level ground.

7. The apparatus as claimed in claim 1 , further comprising endless tracks or wheels movably supporting the main frame on the ground.

8. The apparatus as claimed in claim 1 , wherein the conveyor includes a support structure arranged to mount an endless belt or carriage member configured to support and transport the material relative to the main frame, the pivot joint being mounted between the belt or carriage member and the support region of the main frame.

9. The apparatus as claimed in claim 1 , further comprising a plurality of power operated linear actuators arranged to drive bending or folding of the head section and/or the tail section.

10. The apparatus as claimed in claim 8 , further comprising a conveyor mount frame to suspend the support structure from a turntable or slew ring of the pivot joint.
