Definitions
- the invention relates to a piste grooming device that can be attached to a piste grooming vehicle on the front or rear, on a tool holder of the vehicle, and has a piste treatment tool that can be coupled to the tool holder and a renovation unit provided on the same side of the vehicle.
- a piste grooming device of this type is known from PCT / EP95 / 04233, in which the renovator unit is fastened in the region of the lower rear edge of a dozer blade that is built in front of the vehicle.
- Renovator teeth of the renovator unit are pivotally held in bearing blocks, which are firmly attached to the lower rear edge of the dozer blade.
- the renovator teeth can be pivoted from a standby position into a working position in which the teeth engage in the base of the slope via an adjusting device supported on the clearing blade.
- This renovation unit has proven itself very well in practice. It can be used to tear up and loosen the slope surface. The torn-up clods are shredded by the trailing snow groomer and possibly processed by trailing processing tools. This means that even hard and icy slopes can be prepared for a new, loose slope underlay.
- the invention has for its object to improve a slope grooming device of the type mentioned in such a way that there are better applications for processing the slope surface, the device should be structurally simple and easy to use.
- the renovator unit can thus be provided separately from the processing tool and can be interchangeably attached to the vehicle as an interchangeable adapter.
- the renovator unit can be designed constructively as a separate unit and is therefore very easy to adapt to the desired mode of operation.
- the renovator unit can be attached to the vehicle as a removable adapter, for example, and then uncoupled from it. It can be replaced separately as an adapter, so that the vehicle can be equipped according to the desired application.
- the renovator unit can preferably be coupled to the tool holder.
- the renovator unit itself can thus be coupled directly to the tool holder as an adapter.
- the processing tool or the renovator unit can optionally be coupled directly to the tool holder.
- the processing tool can be attached directly to the tool holder as an alternative to the renovator unit.
- the tool holder it is also conceivable for the tool holder to have two holding units, so that the machining tool and the renovator unit can each be attached to a holding unit independently of one another and can be coupled to one another.
- the renovator unit can advantageously be arranged between the processing tool and the tool holder. This means that the renovator unit and the processing tool work one behind the other in the direction of travel and can thus complement each other for optimal slope preparation. For example, the renovatedor unit can first loosen the subsoil with renovator teeth and the torn clods can then be further shredded by the processing tool and processed to the desired consensus.
- the renovator unit be designed as a holder of the processing tool.
- the processing tool can be held by the renovator unit and e.g. be coupled to and uncoupled from the vehicle.
- Renovator unit and processing tool can thus be designed as a compact unit. Due to the training as a change adapter, the renovator unit serves as a coupling unit for the tool holder.
- the coupling connection of the renovator unit for the tool holder can conceivably correspond to the coupling connection of the processing tool for the tool holder.
- the renovator unit can have a coupling connection for the tool holder on the side facing the vehicle and a holding device for the machining tool on the side facing away from the vehicle.
- the renovator unit is thus fastened to the tool holder and the processing tool can optionally be attached to the holding device.
- the renovationor unit can be coupled to the tool holder alone or the processing tool can also be attached to and held by the renovator unit.
- the actuating device can preferably be articulated on an actuating lever which is separate from the renovator teeth.
- the actuating lever can be designed to be optimized for the actuation of the teeth and can be adapted accordingly to the actuating device.
- the construction can also be chosen so that the actuating device and the actuating lever are arranged at a sufficient distance from the slope surface to be worked.
- the actuating device can have a piston-cylinder unit, the articulation points of which are provided on the renovator unit.
- the piston-cylinder unit is thus supported on the renovator unit, so that the interchangeable adapter can be connected and disconnected independently of the connection requirements of the actuating device.
- several renovator teeth of the renovator unit to be connected by a transverse web which runs transversely to their direction of extension and which engages in the slope surface in the working position of the teeth.
- the crossbar serves as an additional separating and tearing device. In the working position, it separates a layer of the slope surface that is then easy to shred and work on.
- the cross bar also provides additional loosening of the material to be processed.
- the renovator teeth can be designed more as a holding device for the crossbar, with a few renovator teeth being sufficient for this holding function.
- the slope-processing 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. This will lift a layer of the slope surface in the area between the renovator teeth and their articulation point on the renovator unit.
- the crosspiece can conceivably extend parallel to a pivot axis of the renovator teeth.
- the crossbar can expediently be in the working position of the renovator teeth, directed towards the rear of the piste grooming device, at an angle upwards.
- “angled upward” is to be understood as an extension transverse to a horizontal which is oriented towards the sky.
- the separated slope layer is raised slightly and thus loosened up. With some slope layers, the layer breaks easily. Understandably, only a part of the crosspiece can be set up at an appropriate angle in cross-section.
- the crossbar in the working position of the renovator teeth can have an approximately horizontal web section in cross section, behind which a wing web section positioned at an angle upwards is provided on the rear side.
- a layer of the slope is first cut off via the horizontal web section. This layer is raised and loosened up at a slight angle by the wing bridge section.
- the functions of separating, lifting and loosening in the corresponding web sections are thus separated from one another and optimized. It is proposed that a knife edge be formed on the front of the crossbar. The knife edge makes it easier to separate a slope layer.
- the renovator teeth can preferably be almost cut like a knife edge on the front. This makes it easier to tear open the slope surface.
- the processing tool is a dozer blade.
- 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.
- the renovator unit can be coupled as a change adapter as mentioned above.
- the machining tool can be a milling cutter particularly advantageously. Mills are often attached to the rear of a piste grooming vehicle and are retightened.
- the renovator unit can be provided separately from the milling cutter due to the design as an interchangeable adapter. For example, the renovation unit can be provided in front of the cutter in the direction of travel, so that it first tears open and loosens the slope of the slope and the remaining clods are then processed by the cutter.
- the object of the invention is also achieved by a piste grooming vehicle with a piste grooming device according to claim 1. Accordingly, the piste grooming vehicle can also fulfill the features described in the dependent claims.
