Dust fan cap for rock drilling machines

The invention relates to a device for collecting the drilling dust that occurs during drilling upwards with drills or drilling devices, especially in rock.

When drilling overhead, the resulting drilling material trickles Usually in the drill chuck of the drill and 'down on the operator. Fixed, fine, hard particles of the drilling dust get into the drill chuck on the sliding surfaces of the clamping jaws, j Firm and unä hinder the easy sliding of the movable ones Parts. In addition, the sliding

areas destroyed by e; hmirge! effect. The use is harassing the drilling dust as' et not only in the!, Penetrating eyes and sorg ™

Vm the Pindringen of Bohrsfcpub into the chuck of 'au'verhindern drilling machine was beaten before, "a Böhr forage cap on <5s drill' aufZu fceoken ¹ S, which prevents the trickling down Bohrstrub from the chuck and forwards to the outside. However, the drilling dust is thrown off through this circumferential Bohrfutfcerschutakappe and annoys the operator considerably. '-'. . ^! '

According to another "suggestion, the drilling area should be covered by a protective cap and the so" created gesphlosaerje ruuia should be connected to a dust extraction system. Apart from the fact that with this arrangement the drill chuck is not protected against penetration of drilling dust, the necessary hose line is a hindrance when working with the drill. Besides. A special suction fan is required through which the air is sucked out of the drilling area; will., - as well as: a PiLter for separating the Bohrstpubes.

If this is not the case for a particularly long drill when turning, this does not affect the direction of operation , since the drill dust initially falls down along the drill and is only thrown outwards by the 'cover whisk .13' and 'ih': that is: "he at least against the bellows! or. die.7 \ bdeoki ^ ng: -8, 9 »10 hits. When the drill penetrates. 4 ίιαΐthe 'drilling surface, the bellows 7 is gradually': pressed together ■ b, iäw.i '. the lamellae 8 are accordingly spread outwards.

During drilling near the surface, the drill dust emerging from the borehole falls down onto the circumferential cover disk 13 and is thrown outward by this against the bellows 7 or the cover 8, 9-10. There it bounces ₍ eb and falls down into the dust bag 12. Dust grains which, after bouncing off the bellows get into the gap between cap 5 and cover plate 13, are ejected again by the ribs H of the cover plate or ^me'hrex'er; νύτά holes' of the dust bag 12 by simple
