  • Device for clearing a helix gap of an auger, and method for making a drilled hole
    Patent number: 11952838
    Abstract: The invention relates to a device for clearing a helix gap of an auger, comprising a retainer for holding the device on a mast of a drill, a guide tube which surrounds the auger in portions and is mounted on the retainer, and a clearing element which engages in the helix gap and is mounted on the retainer so as to be freely rotatable about the drilling axis. According to the invention it is provided for the guide tube to be mounted on the retainer so as to be freely rotatable about the drilling axis, for the clearing element to be firmly attached to the rotatably mounted guide tube, for the guide tube to be axially fixed in the direction of the drilling axis, for the purpose of clearing, and for the clearing element, together with the guide tube, to be able to be caused to rotate about the drilling axis by means of a pulling procedure of the auger for the purpose of clearing the auger.
