Definitions

  • the invention relates to a piste grooming device that frontoder on a piste grooming vehicle rear, can be attached to a tool holder of the vehicle, and a the piste preparation tool which can be coupled to the tool holder and one on the Has the same side of the vehicle provided renovator unit.
  • a snow grooming device of this type is known from WO 96 22425 A, in which the Renovator unit in the area of the lower rear edge of a built in front of the vehicle Dozer blade is attached. Renovator teeth of the renovator unit can be swiveled held in pedestals at the lower rear edge of the dozer blade are permanently installed. Via an adjusting device supported on the dozer blade can the renovator teeth from a standby position to a working position which engage the teeth in the slope surface, are pivoted.
  • the invention has for its object a piste grooming device of the type mentioned To improve the genus so that it has better applications exist for processing the slope surface, the device being structurally simple should be built and manageable.
  • the renovator unit can thus be provided separately from the processing tool be and be attached to the vehicle as a removable adapter.
  • the Renovator unit can be designed constructively as a separate unit and is therefore very well tunable to the desired mode of action.
  • the renovator unit can be used as a change adapter e.g. even attached to the vehicle and be uncoupled from it. It can be replaced separately as an adapter, so that the vehicle can be equipped according to the intended purpose.
  • the renovator unit can be coupled to the tool holder.
  • the renovator unit itself can be used as an adapter on the tool holder be connectable.
  • either the processing tool or the renovator unit can be coupled directly to the tool holder.
  • This can e.g. the editing tool alternatively to the renovator unit directly on the tool holder be attachable.
  • the tool holder has two receiving units, so that the processing tool and the renovator unit can be attached to a recording unit independently of one another are and can be coupled to one another.
  • the renovator unit can advantageously be located between the processing tool and the tool holder. This means that the renovation unit and processing tool work one behind the other in the direction of travel and can thus be optimal Complement slope preparation.
  • the renovator unit may initially have renovator teeth loosen the subsoil and the torn floes can then further crushed by the processing tool and to the desired consistency are processed.
  • the renovator unit as the holder of the processing tool is trained. This means that the processing tool can be removed from the renovation unit held and e.g. be coupled to and uncoupled from the vehicle.
  • renovator and machining tool can be designed as a compact unit.
  • By training as an interchangeable adapter serves the renovator unit as a coupling unit the tool holder.
  • the coupling connection of the renovator unit for the tool holder is conceivable correspond to the coupling connection of the machining tool for the tool holder.
  • the renovator unit on the vehicle facing can be particularly advantageous Side a coupling connection for the tool holder and on the vehicle have a holding device for the processing tool.
  • the actuating device can preferably be separated from one of the renovator teeth Operating lever be articulated.
  • the operating lever can be used accordingly for the operation of the teeth should be optimized and corresponding to the adjusting device be adjusted.
  • the construction can also be chosen so that the adjusting device and the operating lever is sufficiently spaced from the one to be machined Slope underground is arranged.
  • the actuating device can be a piston-cylinder unit have, the pivot points provided on the renovator unit are.
  • the piston-cylinder unit is thus supported on the renovator unit, see above that the interchangeable adapter is independent of the connection requirements of the actuating device can be coupled and uncoupled.
  • the crossbar serves as an additional separating and Ripping. It separates a layer of the slope surface in the working position which is then easy to shred and process.
  • the crossbar also ensures an additional loosening of the material to be processed.
  • the renovator teeth can be used more as a holding device for the Cross bar be formed, with a few renovator teeth are sufficient for this holding function. It is also understandable that the slope-editing function of the crossbar does not primarily depend on the design of the renovator unit as an interchangeable adapter.
  • the crossbar be arranged at the outer end of the renovator teeth is. This will create a layer of slope surface in the area between the Renovator teeth and their articulation point lifted off the renovator unit.
  • the crosspiece can be parallel to a pivot axis of the renovator teeth extend.
  • the crossbar in the working position of the renovator teeth The rear of the piste grooming device must be angled upwards. Under In this sense, "angled upwards” is an extension transverse to a horizontal understand that is heavenward. Through this alignment of the crossbar the separated slope layer is raised slightly and thereby additionally loosened. With some slope layers, this causes a slight break Shift one. Understandably, only a part of the crossbar in cross section accordingly be angled upwards.
  • the crossbar can preferably be in cross-section in the working position of the renovator teeth have an approximately horizontal web section, behind which an angled behind wing web section above is provided. Over the horizontal web section a layer of the slope is first cut off. Through the wing bridge section this layer is raised and loosened at a slight angle. In order to are the functions of separating, lifting and loosening in the corresponding web sections separated from each other and optimized.
  • a knife edge be formed on the front of the crossbar is.
  • the knife edge makes it easier to cut off a slope layer.
  • the renovator teeth can preferably be chamfered in the manner of a knife edge on the front his. This makes it easier to tear open the slope surface.
  • the processing tool is a dozer blade. So can the renovator unit can be designed separately from the dozer blade as an interchangeable adapter.
  • the snow plow is usually built into a piste grooming vehicle. Separately the renovator unit can be coupled as a change adapter as mentioned above.
  • the processing tool can be a milling cutter particularly advantageously. Milling are often attached to the rear of a piste grooming vehicle and are tightened. Due to the training as a change adapter, the renovated unit can be separated from the Milling machine may be provided. For example, the renovation unit can be in the direction of travel in front of the Milling machine should be provided so that it first tears open the slope of the slopes coarse and loosens and the remaining clods are then processed by the milling machine.
