- the invention relates to a method of generating cracking in rock material, for example when splitting blocks.
- a breaking device which comprises a drilling unit and a cracking unit.
- a drill hole is drilled in the material to be operated on by means of a rock drill machine.
- the drilling unit is moved away from the point of the drill hole, and a cracking unit is moved to its place.
- a cracking tool is inserted into the drill hole and used to generate cracks in the rock.
- the invention relates to a breaking device comprising the above components.
- a drill hole is drilled in a block with a separate rock drill machine, after which an elongated splitting tool is inserted into the drill hole.
- the cross-section of the splitting tool can be widened by wedging it hydraulically, whereby the tool generates cracking in the rock and eventually causes the block to split.
- An object of this invention is to provide a novel and improved method of generating cracking. Further, an object is to provide a novel and improved breaking device.
- the method according to the invention is characterized by using a breaking device which is an independent supplementary device detachably connected to the boom of the work machine; and performing a work cycle relating to the drilling and cracking in the control of the breaking device's own control unit independently of the work machine.
- the breaking device according to the invention is characterized in that the breaking device is an independent supplementary device detachably connectable to the boom of the work machine; and the breaking device comprises at least one control unit of its own, arranged to control the steps according to the work cycle of the breaking device independently of the control system of the work machine.
- the breaking device is an independent supplementary device which may be detachably attached to the boom of the work machine.

- the control unit of the breaking device controls the steps required by the work cycle of the breaking device after the breaking device has been positioned, by means of the boom of the work machine, at the point to be operated on.
- An advantage of the invention is that an independent breaking device constructed as a supplementary device may be attached to the boom of any work machine used at the work site when there is a need to break large rocks and blocks, for instance. In such a case, no separate, laborious drill machine or cracking device is needed and, on the other hand, no rock drilling rig intended only for cracking is needed.

- indexing takes place exactly along a predetermined path of movement.
- it is simple to implement the indexing mechanically without measuring and complex controlling of movements.

- the drilling unit 12 can be indexed, in a manner shown in Figure 2a, to an operating centre 29, i.e. to the centre line of a drill hole 30 to be drilled, and further, the cracking unit 13 can be indexed, in a manner shown in Figure 2b, to the operating centre 29. Since the drilling unit 12 and the cracking unit 13 are both attached to the slide piece 27, they move simultaneously in the indexing.
