Abstract

A mobile bulk material processing apparatus includes a main frame having a pair of opposed beams that are spaced apart in a widthwise direction across the apparatus. A conveyor transports material from or to a material processing unit mounted at the main frame. The beams are arranged to receive at least part of the conveyor to protect the conveyor in a raised transport position.

First claim

The invention claimed is:

1. A mobile bulk material processing apparatus comprising:
a longitudinally extending main frame having a first end and a second end, the main frame including a base region for mounting a pair of endless tracks or wheels to allow the apparatus to move over the ground, a neck section extending upwardly from the base region, and a pair of spaced apart opposed beams projecting towards the first end from an uppermost part of the neck section;
a conveyor to transport material from or to a material processing unit mounted at the main frame; and
at least one coupling to mount the conveyor at the main frame for movement between a raised transport position and a lowered operative position, such that at least a part of the conveyor is accommodated between the beams substantially at the first end when in the raised transport position.

2. The apparatus as claimed in claim 1 , further comprising at least one cross beam or brace extending between and linking the opposed beams in a widthwise direction of the apparatus.

3. The apparatus as claimed in claim 1 , wherein the at least one coupling includes a pivot joint to allow the conveyor to pivot relative to the main frame to change a position of a distal end of the conveyor relative to the main frame.

4. The apparatus as claimed in claim 3 , wherein the pivot joint is mounted and suspended below the opposed beams.

5. The apparatus as claimed in claim 3 , further comprising a first bracket to couple the pivot joint to the main frame and a second bracket to couple the pivot joint to the conveyor such that the second bracket is configured to pivot relative to the first bracket.

6. The apparatus as claimed in claim 1 , wherein the conveyor includes a head and tail section pivotally mounted together to allow the head section to bend or fold relative to the tail section to raise and lower a distal end of the conveyor relative to the opposed beams.

7. The apparatus as claimed in claim 6 , wherein the head section is positionable between the opposed beams when the conveyor is raised to the transport position.

8. The apparatus as claimed in claim 6 , further comprising a plurality of power operated linear actuators to drive bending or folding of the head section relative to the tail section.

9. The apparatus as claimed in claim 3 , wherein the conveyor includes a support structure to mount an endless belt or carriage member configured to support and transport the material relative to the main frame, wherein the pivot joint is mounted between the belt or carriage member and the opposed beams in a substantially vertical direction.

10. The apparatus as claimed in claim 1 , wherein a distal end of the conveyor is arranged to project longitudinally from between the beams beyond the first end of the main frame.

11. The apparatus as claimed in claim 1 , further comprising a screening unit mounted at the main frame to process material and to feed at least some of the processed material to the conveyor.

12. The apparatus as claimed in claim 1 , wherein the material processing unit includes a crusher mounted at the base region of the main frame.
