Definitions
- Rocks and especially minerals are usually mined by drilling and shooting - with the known disadvantages.
- Activation from the inside or outside means that disks, disks or the like - with or without teeth - can be activated on the inside, e.g. by eccentric, - or the entire drilling tool from the outside e.g. is acted upon by an eccentric or unbalance impact device and is thus activated.
- the self-controlling drilling unit according to the invention not only has the advantage that it does not require any control electronics or a man to control it, but that the drilling material can be freely picked up behind the drilling tools, ie can be removed; blades can also be installed on the rotating drilling tool - as separate protection.
- the drawing 1 shows under 1 the undercutting, removing, rotating, disc or disc tool, -2 is the rotating or swiveling arm of the drilling tool, -3 is the rock contour before the undercut and -4 after the undercut, which is the arrow the direction of advance.
- drawing 2 5 are the horizontal and 6 are the vertical pre-cuts, among others. to relax or to be able to blow off or drill off rectangular cubes of stone according to claim 6.
- Fig. 3 7 is again the disc or disc tool and 8 is a rotating or oscillating arm, 9 is the front of the frame before - and 10 after removal - according to FIG. 1, only in a different view.
- 11 is a conventional feed device and 12 the drilling head rotating in this embodiment with a plurality of disc or disk tools - arranged in a line, undercutting only one layer or drilling only one slot; staggered but multiple, undercutting or slitting - e.g. 5-
- a self-propelled crawler or wheel chassis can also be used - with a propulsion and a side component.
- the outer caterpillar provides more propulsive power - the axles are angled on wheels - in order to apply the components required for pressure and guidance; - separate protection is required for this.
- 21 shows an undercut / removal tool with only one cut, in this embodiment - for which separate protection is requested - a self-rotating conical disc mounted on a motor-driven eccentric and thus independently rotating in opposite directions, working with teeth or the like - driven milling can work.
- only one disc drilling tool removes the entire excavation front / height in just one shift.
- the systems explained above can of course also be used to remove horizontal layers - for example to remove road surfaces. - Special protection is requested for this.
- a process patent is claimed to protect with cutting tools 21 in direction 22 - for relaxing and / or calibrating - in order to then remove undercut tools 23 in approximately one slot depth and height in one or more layers - for example in one height from about 20 - 30 cm to selectively win reef; at a distance behind it - in order to be able to remove the removed material beforehand - the upper and lower residual layers are cut to the same depth as before using the two drilling tools 24 shown, for example the total height of the 'stop', e.g. 1.20 m.
- All of the above-described slitting / removal tools are preferably instructed on a machine frame (not shown) which, according to the invention, is preferably guided on the pre-processed / pre-cut removal front.
- the pre-cutting or ablating tools 21 and 23 can preferably be adjusted in height - for example in order to be able to follow the reef better - the re-cutting tools 24 have a larger diameter than the one shown.
- FIG. 8 explains FIG. 7 again, 25 again being the pre-cutting tool - 26 the undercutting tool and 27 the tool removing the bedrock. 26 can also be arranged so that they can be swiveled and / or moved - with which the tools 27 could be dispensed with. 28 is the contour of the original mining front. Special protection is requested for the inventive systems of protection, undercutting and the like, to only allow the active front cutting radius to rest on the wall, i.e. not to uselessly grind or wear the rear side of the bisque or cutting tools on the wall due to a small cutting angle, see FIG. 6, tool 21. A tool arrangement is shown in dashed lines at 21a, with which a second, third, etc. removal can be carried out in one Arbeltsgang can take place - special protection is requested for this tool order - also for the application of this technique on pendulum-or. rotating cutting tools according to Figure 3 -7- and -8- or Figure 4 -12-.
- FIGS. 9 and 10 show how, in particular, pre-drilled holes are expanded radially from the inside to the outside with the use of the undercutting ablation technique, especially in order to drill arch profiles.
- Figure 9 -29- is the holding and turning device, -30- a version of a scaring and / or striking undercutting thickness / disc or similar tool with self-drive Figure 10 -33- or -34- with activation, the can also drill "on the spot"; -31- is the rock outline before the undercutting removal, -32- is the extendable, slowly rotating hydraulic cylinder driven by -29- and held from cut to cut without feed.
- FIG. 10 shows an arc profile - without a pre-drilled hole and a rotary / feed / extension device (not shown) with a special drilling system / tool -33-, which corresponds to that in FIG. 4 -12- - but removes layers radially from the inside to the outside - with the inventive advantage to be able to drill any - not just circular profiles.
- this system can of course also remove layers in several stages or work with the activated cutting head 34. For this system of subsequent boring / expanding circular
- Sole - separate protection is requested.
