Abstract

A conveyor comprises a first conveyor section and a second conveyor section that is foldable with respect to the first conveyor section. Skirting is movable into and out of a deployed state in which it extends along the second conveyor section. A skirting support is coupled to the skirting and is movable into and out of a deployed state in which it holds the skirting in the deployed state. Actuating device is provided for moving the skirting support. The skirting is deformable or foldable so that it does not have to be removed or fitted when the conveyor is folded or deployed, and is less susceptible to damage.

First claim

We claim:

1. A conveyor comprising a first conveyor section and a second conveyor section movable with respect to said first conveyor section between a deployed state and a non-deployed state, the conveyor further comprising:
at least one skirting movable into and out of a deployed state in which said at least one skirting extends along the second conveyor section;
at least one skirting support coupled to said at least one skirting and movable into and out of a deployed state in which said at least one skirting support holds said at least one skirting in its deployed state; and
actuating means for moving said at least one skirting support,
wherein said at least one skirting is deformable or foldable,
and wherein the, or each, skirting support is movable between said deployed state in which the skirting support holds the respective skirting in a raised position, with respect to said second conveyor section, and a non-deployed state in which the respective skirting adopts a lowered position with resect to said second conveyor section.

2. The conveyor of claim 1 , wherein said at least one skirting is formed from a flexible material.

3. The conveyor of claim 1 , wherein the, or each, skirting is coupled to the respective skirting support at a first coupling point, and wherein the skirting support is movable between said deployed state in which said coupling point is in a raised position with respect to said second conveyor section, and a non-deployed state in which the coupling point is in a lowered position with respect to said second conveyor section.

4. The conveyor of claim 1 , wherein the, or each, skirting is coupled to the respective skirting support by a spring tensioned flexible line.

5. The conveyor of claim 4 , wherein when the skirting is in its deployed state said flexible line holds said skirting in tension, and wherein when the skirting is in its non-deployed state said flexible line does not hold said skirting in tension.

6. The conveyor of claim 1 , wherein the or each skirting is movable between said deployed state and a non-deployed state in which the skirting adopts a lowered position with respect to said second conveyor section in comparison with a position of said skirting in its deployed state.

7. The conveyor of claim 1 , wherein the or each skirting is movable between said deployed state and a non-deployed state in which the skirting is deformed with respect to the deployed state of the skirting.

8. The conveyor of claim 1 , wherein the or each skirting is coupled between the first conveyor section and said second conveyor section such that movement of the second conveyor section from its non-deployed state to its deployed state causes the skirting to adopt its deployed state, and movement of the second conveyor section from its deployed state to its non-deployed state causes the skirting to adopt a non-deployed state.

9. The conveyor of claim 1 , wherein said actuating means is configured to move the or each skirting support between its deployed state and a non-deployed state.

10. The conveyor of claim 1 , wherein said second conveyor section is pivotable with respect to said first conveyor section.

11. The conveyor of claim 1 , wherein said first conveyor section is a base section of the conveyor, the base section optionally including a feed chute.

12. The conveyor of claim 1 , wherein said actuating means comprises a linkage coupled between the skirting support and the first conveyor section, or other base structure, such that movement of the second conveyor section between its deployed and non-deployed states causes the linkage to move the skirting support between its deployed and non-deployed states, the linkage optionally being pivotably coupled to the first conveyor section, or other base structure, and to the skirting support.

13. The conveyor of claim 12 , wherein the or each skirting support is pivotably coupled to the second conveyor section for pivoting movement between its deployed state and a non-deployed state, and wherein the linkage is coupled to the skirting support at a second coupling point such that the pivot axis of said skirting support is located between the second coupling point and the point at which the respective skirting is coupled to the skirting support.

14. The conveyor of claim 1 , wherein said actuating means comprises resilient biasing means configured to urge the or each skirting support to adopt its deployed state, and/or wherein the actuating means comprises an actuator.

15. The conveyor of claim 1 , wherein the conveyor is included in a material processing apparatus comprising a material processing unit.

16. A conveyor comprising a first conveyor section and a second conveyor section movable with respect to said first conveyor section between a deployed state and a non-deployed state, the conveyor further comprising:
at least one skirting movable into and out of a deployed state in which said at least one skirting extends along the second conveyor section;
at least one skirting support coupled to said at least one skirting and movable into and out of a deployed state in which said at least one skirting support holds said at least one skirting in its deployed state; and
actuating means for moving said at least one skirting support,
wherein said at least one skirting is deformable or foldable,
and wherein said at least one skirting comprises a plurality of rigid or semi-rigid sections interconnected by at least one joint.

17. A conveyor comprising a first conveyor section and a second conveyor section movable with respect to said first conveyor section between a deployed state and a non-deployed state, the conveyor further comprising:
at least one skirting movable into and out of a deployed state in which said at least one skirting extends along the second conveyor section;
at least one skirting support coupled to said at least one skirting and movable into and out of a deployed state in which said at least one skirting support holds said at least one skirting in its deployed state; and
actuating means for moving said at least one skirting support,
wherein said at least one skirting is deformable or foldable,
and wherein the, or each, skirting is coupled to the respective skirting support by a flexible line.

18. A conveyor comprising a first conveyor section and a second conveyor section movable with respect to said first conveyor section between a deployed state and a non-deployed state, the conveyor further comprising:
at least one skirting movable into and out of a deployed state in which said at least one skirting extends along the second conveyor section;
at least one skirting support coupled to said at least one skirting and movable into and out of a deployed state in which said at least one skirting support holds said at least one skirting in its deployed state; and
actuating means for moving said at least one skirting support,
wherein said at least one skirting is deformable or foldable,
and wherein the or each skirting support is pivotably coupled to the second conveyor section for pivoting movement between its deployed state and a non-deployed state.

19. A conveyor comprising a first conveyor section and a second conveyor section movable with respect to said first conveyor section between a deployed state and a non-deployed state, the conveyor further comprising:
at least one skirting movable into and out of a deployed state in which said at least one skirting extends along the second conveyor section;
at least one skirting support coupled to said at lea
