  • the invention relates to a trench cutter according to the preamble of claim 1 and to a method for creating a slot in the floor according to the preamble of claim 13.
  • Such a trench wall cutter comprises a trimming frame and at least one cutting wheel mounted rotatably about a rotation axis on the trimming frame, which has on its outer circumference a plurality of soil working tools for removing soil material which are arranged along an annular path around the axis of rotation.
  • a trench cutter of the type mentioned is for example in the DE 10 2007 035 591 B3 described.
  • the invention has for its object to provide a trench cutter and a method for creating a slot in the ground, which allow a particularly economic Schlitzwander ein.
  • the trench wall cutter according to the invention is characterized in that the annular path is asymmetrical to the axis of rotation of the cutting wheel, wherein the annular path has at least a first peripheral portion at a greater distance from the axis of rotation and at least a second peripheral portion at a smaller distance from the axis of rotation.
  • the method is inventively characterized in that the annular path is asymmetrical to the axis of rotation of the cutting wheel, wherein the annular path has at least a first peripheral portion at a greater distance from the axis of rotation and at least a second peripheral portion at a smaller distance from the axis of rotation and wherein the trench wall cutter during operation is put into a defined vibration.
  • a first basic idea of the invention can be seen to produce a defined non-circular run of the cutting wheel by the asymmetrical arrangement of the tillage tools.
  • the non-circular run is achieved in that the ring track, on which the tillage tools are arranged in the circumferential direction, no circular path about the axis of rotation of the cutting wheel as a circle center.
  • the tillage tools are thus arranged deviating from a point-symmetrical to the axis of rotation of the cutting wheel circular path.
  • the tilling tools are further away from the axis of rotation and at least in a second portion closer to the axis of rotation.
  • the tillage tools may be, in particular, cutting teeth, chisels, rollers or rollers.
  • the tillage tools are used for loosening or removing soil material for creating a slot in the ground and are arranged for this purpose on an outer periphery of the cutting wheel.
  • the distance of the tillage tools from the axis of rotation of the cutting wheel changes defined, in particular gradually, in the circumferential direction along the annular path.
  • the tilling tools are in particular arranged such that the distance from the axis of rotation along the annular path increases and decreases periodically along a plurality of tillage tools.
  • the distance of the tilling tools from the axis of rotation in the circumferential direction of the cutting wheel increases successively along a first section via a plurality of tillage tools and then successively along a second section via a plurality of tillage tools again.
  • the tillage tools arranged according to the invention cause a rotation of the cutting wheel about its axis of rotation a periodically changing distance of the axis of rotation to the resultingewedfräsenden soil.
  • the ring track, on which the soil working tools are arranged around the cutting wheel can be offset and / or distorted in particular in relation to a circular path which is point-symmetrical with respect to the axis of rotation of the cutting wheel.
  • the tillage tools are arranged on a rotationally asymmetric to Fräsradfilachse ring track, that is, a rotation of the cutting wheel at an arbitrary angle does not form the ring track on itself, but forms an offset and / or twisted annular path with respect to the original ring path.
  • the ring track, along which the tillage tools are arranged, may also be referred to as a cutting path.
  • a rotation of the cutting wheel By a rotation of the cutting wheel, the position and / or orientation of the cutting path changes with respect to the axis of rotation of the cutting wheel.
  • a defined vibration of the trench wall cutter can be generated on the basis of the asymmetrical ring path to the axis of rotation of the cutting wheel.
  • Another advantage is therefore to put the trench wall cutter in a defined vibration. Due to the weight of the trench wall cutter and / or a generated pressure force, a lower peripheral portion of the cutting wheel is in operation at the bottom of the slot. By changing in the circumferential direction of the cutting wheel distance of the tillage tools from the axis of rotation, the axis of rotation of the cutting wheel at a contacting of the respective underlying tillage tools with the bottom of the slot is periodically moved up and down. This causes a vibration of the cutting frame or the trench wall cutter.
  • the dynamic force on the tillage tools is further increased and a beating soil removal possible.
  • the soil can thus be solved in addition to grinding by knocking, so that a frictional wear on the tillage tools can be reduced and an even more effective soil removal can be realized.

  • the difference between a maximum distance and a minimum distance of the tillage tools from the axis of rotation is about a few millimeters or centimeters and one or two decimeters.
  • the position of the ring track or the axis of rotation of the cutting wheel is adjustable. For example, with harder ground formations, a greater eccentricity of the cutting wheel can be set than with softer soils.

It is particularly preferred in this context that the individual cutting wheels are driven at the same speeds, but the angles of rotation, based on the orientation of the annular path to the axis of rotation, are offset from one another.
  • a further oscillation superimposition in a trench wall cutter with two pairs of cutting wheels is achieved in that the first and second pair of cutting wheels are of the same design but are arranged and driven at a 45 ° angle offset from one another. This results in a superimposition of four mutually phase-shifted by 45 ° vibrations.
