Abstract

A material processing apparatus comprising a rotary operating device coupled to a material processing device, especially a crusher. A primary drive system is coupled to the rotary operating device. An auxiliary drive system has a rotary drive member and is operable between a driving state, in which it is coupled to the rotary operating device, and a non-driving state in which it does not rotate the rotary operating device. The apparatus is operable in a primary mode in which the primary drive system rotates the rotary operating device and the auxiliary drive system is in its non-driving state, or in an auxiliary mode in which the auxiliary drive system is in its driving state. In the auxiliary mode, the auxiliary drive system may be operated to repeatedly rotate the rotary operating device alternately in both rotational directions to impart a back-and-forth rocking motion to the material processing device.

First claim

The invention claimed is:

1. A material processing apparatus comprising:
a material processing device;
a rotary operating device coupled to said material processing device for the operation thereof:
a primary drive system coupled to said rotary operating device and being operable to rotate said rotary operating device;
an auxiliary drive system having a rotary drive member, said auxiliary drive system being operable between a driving state, in which said rotary drive member is coupled to said rotary operating device and is operable to rotate said rotary operating device, and a non-driving state in which said auxiliary driving system does not rotate said rotary operating device,
wherein said processing apparatus is operable in a primary mode in which said primary drive system rotates said rotary operating device and said auxiliary drive system is in said non-driving state, or in an auxiliary mode in which said auxiliary drive system is in said driving state and operated to rotate said rotary operating device,
and wherein said rotary operating device comprises male and/or female formations for engagement with corresponding female and/or male formations provided on said rotary drive member.

2. The apparatus of claim 1 wherein, in said auxiliary mode, said primary drive system is deactivated.

3. The apparatus of claim 1 wherein, in said non-driving state, said rotary drive member is disengaged from said rotary operating device.

4. The apparatus of claim 1 wherein said rotary drive member is movable into and out of engagement with said rotary operating device, said rotary drive member being in engagement with said rotary operating device when said auxiliary drive system is in said driving state, and said rotary drive member being disengaged from said rotary operating device when said auxiliary drive system is in said non-driving state.

5. The apparatus of claim 1 wherein said male and/or female formations are spaced apart around a circumferential surface of said rotary operating device.

6. The apparatus of claim 5 wherein said circumferential surface faces inwardly towards the axis of rotation of said rotary operating device.

7. The apparatus of claim 5 wherein said circumferential surface faces outwardly away from the axis of rotation of said rotary operating device.

8. The apparatus of claim 5 wherein said rotary operating device includes a chain, a respective one of said female formations being provided by each link of said chain.

9. The apparatus of claim 8 wherein said chain extends around said circumferential surface of said rotary operating device.

10. The apparatus of claim 1 , wherein said female and/or male formations are spaced apart around a circumferential surface of said rotary drive member.

11. The apparatus of claim 1 wherein said rotary operating device includes a plurality of female formations spaced apart around said circumferential surface.

12. The apparatus of claim 1 wherein said rotary drive member comprises a sprocket, including male formations in the form of a plurality of teeth spaced apart around its circumference.

13. The apparatus of claim 1 wherein said formations have a respective longitudinal axis extending obliquely to or parallel with the rotational axis of said rotary operating device and said rotary drive member.

14. The apparatus of claim 1 wherein said formations comprise respective mating surfaces at which respective male and female formations engage and by which rotational movement is imparted, said mating surfaces extending obliquely to and/or parallel with the rotational axis of said rotary operating device and said rotary drive member.

15. The apparatus of claim 1 wherein said auxiliary drive system comprises a motor for rotating said rotary drive member.

16. The apparatus of claim 15 wherein said motor comprises a hydraulic motor.

17. The apparatus of claim 1 wherein said auxiliary drive system is operable in a neutral mode in which said rotary drive member is freely rotatable.

18. The apparatus of claim 17 wherein said motor comprises a hydraulic motor and wherein said rotary drive member is coupled to said motor by a clutch, said clutch disengaging said motor from said rotary drive member in said neutral mode, or wherein said motor is operated by a hydraulic circuit configurable to allow said motor to rotate freely.

19. The apparatus of claim 1 wherein said auxiliary drive system includes a carriage that carries said rotary drive member, the carriage being movable with respect to said rotary operating device into and out of a position in which said rotary drive member engages with said rotary operating device such that said respective male and female formations inter-engage.

20. The apparatus of claim 19 wherein said carriage is pivotably movable with respect to
said rotary operating device.

21. The apparatus of claim 20 wherein said carriage is pivotably coupled to said material processing device.

22. The apparatus of claim 20 herein said carriage is power operable into and out of said engaging position.

23. The apparatus of claim 1 , wherein said rotary operating member comprises a fly wheel, and wherein in said driving state said rotary drive member is coupled to said fly wheel.

24. The apparatus of claim 1 , wherein said primary drive system comprises a motor coupled to said rotary operating device for the rotation thereof.

25. The apparatus of claim 24 , wherein said rotary operating member comprises a fly wheel,
and wherein said motor is coupled to said fly wheel.

26. The apparatus of claim 24 , wherein said motor is coupled to said rotary operating device by a drive belt, the belt being driven by a pulley coupled to said motor.

27. The apparatus of claim 26 , wherein said pulley is coupled to said motor by means of a clutch.

28. The apparatus of claim 26 , wherein said motor drives said pulley directly in use.

29. The apparatus of claim 1 , wherein said primary drive system is operable to impart rotational movement to said rotary operating device in one rotational direction only.

30. The apparatus of claim 1 , wherein said auxiliary drive system is operable to impart
rotational movement to said rotary operating device in either rotational direction.

31. The apparatus of claim 30 , wherein said auxiliary drive system motor is capable of
rotating said drive member in either rotational direction about its rotational axis.

32. The apparatus of claim 30 , wherein, in said auxiliary mode, the auxiliary drive system is operated to rotate said rotary operating device alternately in both rotational directions.

33. The apparatus of claim 32 , wherein, in said auxiliary mode, the auxiliary drive system is operated to repeatedly rotate said rotary operating device alternately in both rotational directions to impart a hack-and-forth rocking motion to the material processing device.

34. The apparatus of claim 1 , wherein said material processing device comprises a crusher.

35. The apparatus of claim 34 , wherein said crusher comprises a jaw type crusher.

36. A material processing apparatus comprising:
