Definitions
- the invention relates to a drilling device with a
- Senkhammer drill heads are used for well drilling and other deep hole drilling in rock and stone.
- the sink hammer is powered by compressed air supplied through the drill pipe. The compressed air emerges at the percussion drill bit and conveys the resulting cuttings upwards.
- apron which is open at the bottom and which receives the cuttings which have been knocked loose by the hammer of the drill head so that it can be conveyed upwards.
- the sealing disk has a plurality of sealing lips on the circumference one above the other. This results in a significant increase in the sealing effect compared to a single sealing lip.
- the rigid annular disks 18 are connected to one another by screws 20, 21. Near their inner edge, the rigid sealing disks 18 are connected to one another by screws 21 and to an upper flange 22 of the slide bearing bush 16.
