Definitions

  • the invention relates to an auger device according to the preamble of claim 1.
  • Such an auger is formed with a auger, a cladding tube surrounding the auger, a rotary drive for rotationally driving at least the auger about a drilling axis, an ejector for discharging cuttings from the auger wherein the ejection device comprises a collecting container and a discharge line for the cuttings, a mast element, along which the auger is displaceable with the ejection device, and a device for changing the length (L) of the discharge line.
  • a device for cased Erdbohren is for example from the JP 60-238516 A known.
  • this known drill an ejection opening is provided at the upper end of the cladding tube below the Bohrcardantriebes through which the subsidized by the auger cuttings can escape. From the discharge opening the cuttings fall along the casing tube next to the drill pipe to the ground. Since the Bohrgutaussch takes place at the level of the rotary drive, in particular at the beginning of the bore, when the rotary drive is still far from the ground, given a large drop height. It may therefore be necessary special security measures to avoid accidents caused by falling cuttings. In addition, the largely uncontrolled Bohrgutaussch at the height of the rotary gear can bring a significant pollution of the site with it.
  • the from the JP 06-257363 known laxative bag is designed so that it extends to just above the ground with completely drawn drilling tool. This is accompanied by a comparatively long length, so that the fabric bag can move in the wind undesirably and get caught on the device. In addition, especially with larger drilling depths, clogging of the bag may occur, especially if the cuttings are moist and settle on the bag.
  • the generic DE 201 01 657 U1 describes a drill with a drill and a scraper housing for the drill, wherein the Bohrgutauslass the scraper housing is in communication with a variable-length discharge chute.
  • This discharge chute can have a plurality of interlocking funnel parts.
  • the JP 11-200749 A relates to a drill with a bellows-type discharge tube.
  • the object of the invention is to provide a Erdbohr réelle, in which a particularly safe, clean and reliable Bohrgutabschreib is given.
  • a basic idea of the invention can be seen in providing the discharge line for the ejected cuttings variable in length. This makes it possible to adjust the length of the discharge line to the current drilling depth, that is, the discharge line when drilling down, so if the ejector is lowered with the auger and / or the cladding tube to the ground, to shorten, and to extend the discharge line when pulling again. In this way it can be ensured that the end discharge opening of the discharge line is always arranged a little above the ground, so that it is prevented that the discharge line rests on the ground during downwards drilling. In this way, a continuous Bohrgutabhne be guaranteed from the discharge line even at large drilling depths, which in turn is counteracted clogging of the discharge line.
  • the discharge line can be designed, for example, as a slide open on one side.
  • the discharge line is designed as a discharge pipe.
  • a change in length of the discharge line can be effected, for example, that additional elements are attached to this or removed from it. If a flexible discharge line, for example a fabric hose, is used, the line could be shortened, for example by rolling up or shirring. It is particularly advantageous, however, that the discharge line is telescopic. In a telescopic design of the discharge line, a change in length of the line can be carried out in a particularly simple and reliable manner. A telescopic design of the discharge line is particularly advantageous if the discharge line to reduce the susceptibility to wind is to be rigid.
  • the discharge line has a multiplicity of pipe elements which can preferably be inserted into one another for shortening the discharge line.
  • a telescopic function can be realized in a particularly simple manner.
  • the tube elements taper towards an end region.
  • the telescoping retraction of adjacent pipe elements into each other is ensured in this case by the taper of the pipe elements.
  • the tapers suitably run in such a way that the diameter of the tube elements decreases with increasing distance from the rotary drive, that is usually towards the ground.
  • the elements may optionally be referred to as a funnel due to their shape, in which case the entire discharge line can be referred to as a funnel chain.
  • the tapers are suitably conical tapers. Except by tapers in the tubular elements can be a telescopic Leakage also be given by the fact that pipe elements of different cross-section are used.
  • a further particularly preferred embodiment of the invention is that the means for changing the length of the discharge line has at least one pull rope and that the means for changing the length of the discharge line further preferably comprises at least one winch means for changing the free length of the pull rope.
  • a structurally particularly simple mechanism for changing the length of the discharge line is given by the fact that the pull rope is attached to at least one of the tube elements.
  • the pull rope is attached to an end pipe element, that is, in particular to a pipe element, which is farthest from the rotary drive and / or arranged closest to the ground.
  • the discharge line can be telescoped over its entire length, wherein when shortening first arranged in the end region of the discharge pipe elements, that is, the lower, near-bottom pipe elements, are retracted into each other and these gradually take the overlying pipe elements.
  • the remaining pipe elements are each guided longitudinally displaceable on the traction cable.
  • the tube elements suitably guide openings through which the pull rope is performed, so that the tube elements along the pull rope are freely displaced.
  • the pull rope is used not only for holding a tubular element but also for lateral stabilization of the remaining, arranged above tubular elements.
  • the pull rope runs through guides on the tube elements, the pull rope below each of these guides each having a driver in the form of a cable support. In this way it can be provided that the distances between the individual pipe elements are shorter when the free length of the traction cable decreases and move the individual pipe elements into each other.
  • stop elements can be provided on the tube elements, which limit an axial relative movement of the individual tube elements relative to each other.
  • stop elements may be provided on the upper side of the tubular elements, a radially projecting stop element, which comes into contact with a radially inwardly projecting stop element of the overlying tube element upon reaching a maximum Ausziehweges.
  • adjacent pipe elements are each connected to each other with at least one tether.
  • the tether is attached at the opposite ends or at the upper end of the adjacent tubular elements.
  • adjacent pipe elements are connected to each other with three tethers, which are distributed equidistantly on the circumference of the pipe elements.

  • the sump is at the top, that is arranged at the end remote from the ground end of the cladding tube and / or underside on the rotary drive.
  • an ejection channel for supplying cuttings into the discharge line is provided on the collecting container.
  • the discharge channel preferably points away from the collecting container.
  • the discharge channel expediently ends above the uppermost tubular element of the discharge line, so that cuttings can be poured into the discharge line in a simple manner.
