Einsatz für Pistenraupen. Use for snow groomers.
Description
Die Erfindung betrifft eine Fräseinrichtung zur Bearbeitung einer Schneepistenoberfläche, die heckseitig an einer Pistenraupe anbaubar ist, mit wenigstens einer Fräswelle, die von einem Fräsengehäuse umgeben und motorisch antreibbar ist, sowie mit einem Heckfinisher zur Glättung der Pistenoberfläche, der rückseitig an das Fräsengehäuse anschließt.The invention relates to a milling device for processing a snow slope surface, which is attachable to a snow groomer, with at least one milling shaft, which is surrounded by a milling housing and driven by a motor, and with a rear finisher for smoothing the slope surface, which adjoins the back of the milling housing.
Eine derartige Schneefräseinrichtung ist bei Pistenraupen, die in Skigebieten eingesetzt werden, allgemein bekannt. Die bekannte Fräseinrichtung ist als Heckanbaugerät an die Pistenraupe ausgeführt. Ein Anbaurahmen, der mit einem Heckträger der Pistenraupe verbindbar ist, trägt ein Fräsengehäuse, in dem zwei oder drei koaxial nebeneinander angeordnete Fräswellen vorgesehen sind. Das Fräsengehäuse ist zwei- oder dreiteilig ausgeführt, so dass für jede Fräswelle ein separater Fräsraum zur Verfügung steht. An das Fräsengehäuse anschließend ist ein Heckfinisher vorgesehen, der den gefrästen Schnee glättet und so die bearbeitete Pistenoberfläche bildet. Bei der bekannten Fräseinrichtung treten bezüglich der bearbeiteten Pistenoberfläche zum Teil größere Qualitätsunterschiede auf, abhängig von der Art und der Menge des zu fräsenden Schnees.Such a snow milling device is well known in snow groomers that are used in ski resorts. The well-known Fräseinrichtung is designed as a rear attachment to the snowcat. An attachment frame, which is connectable to a rear carrier of the snow groomer, carries a milling housing, in which two or three coaxially juxtaposed cutter shafts are provided. The milling housing is designed in two or three parts, so that a separate milling space is available for each milling shaft. Then a rear finisher is provided to the milling housing, which smoothes the milled snow and thus forms the machined slope surface. In the known milling device, there are some major differences in quality with respect to the surface of the runway being processed depending on the type and quantity of snow to be milled.
Aufgabe der Erfindung ist es, eine Fräseinrichtung der eingangs genannten Art zu schaffen, die unabhängig von Art und Menge des zu bearbeitenden Schnees eine gute Qualität der bearbeiteten Pistenoberfläche ermöglicht.The object of the invention is to provide a milling device of the type mentioned, which allows a good quality of the machined runway surface regardless of the type and amount of snow to be processed.
Diese Aufgabe wird dadurch gelöst, dass das Fräsengehäuse auf einer der wenigstens einen Fräswelle zugewandten Gehäuseinnenseite mit Leitelementen versehen ist, die eine Lenkung von durch die Fräswelle erfassten und in das Fräsengehäuse geschleuderten Schneemengen insbesondere nach außen oder nach innen - auf eine Längsachse des Fräsengehäuses bezogen - vornehmen. Unter dem Begriff der "Schneemenge" ist harter und weicher Schnee wie auch Eis oder Schnee-/Eisgemisch zu verstehen. Über die Leitelemente ist eine Steuerung der durch die Fräswellen aufgenommenen Schneemengen innerhalb des Fräsengehäuses und damit eine definierte Verteilung des Schnees über die Pistenoberfläche ermöglicht. Die erfindungsgemäße Lösung eignet sich in besonders bevorzugter Weise für eine heckseitig an eine Pistenraupe anbaubare Fräseinrichtung, die auch als Heckfräse bezeichnet wird. Entsprechende Kettenlaufwerke der Pistenraupe lockern den Untergrund bereits auf, bevor die Fräsfunktion der Heckfräse einsetzt.This object is achieved in that the milling housing is provided on one of the at least one milling shaft facing inside of the housing with guide elements that a steering of the milling shaft detected and thrown into the milling housing snow amounts in particular outward or inward - relative to a longitudinal axis of the milling housing - make. The term "amount of snow" means hard and soft snow as well as ice or snow / ice mixture. Via the guide elements, a control of the amounts of snow absorbed by the cutting shafts within the milling housing and thus a defined distribution of the snow over the runway surface is made possible. The solution of the invention is particularly suitable for a rear attachable to a snow groomer milling device, which is also referred to as a rear grinder. Corresponding caterpillars of the snow groomer already loosen the ground before the milling function of the rear tiller begins.
In Ausgestaltung der Erfindung sind die Leitelemente beweglich angeordnet und durch wenigstens eine Stelleinrichtung verstellbar. Je nach zu fräsender Schneeart und -menge wird eine Verstellung der Leitelemente vorgenommen, um bei unterschiedlichen Schneebedingungen eine gleichbleibende Qualität der bearbeiteten Pistenoberfläche zu ermöglichen. Vorzugsweise werden die Leitelemente so gestellt, dass bei großen Neuschneemengen der Schnee von den Außenseiten der Fräseinrichtung, d.h. von den seitlichen Bereichen der wenigstens einen Fräswelle zur Mitte hin transportiert wird. Bei geringeren, zu bearbeitenden Schneemengen werden die Leitelemente vorzugsweise derart radial zur Drehachse der Fräswelle ausgerichtet, dass der bearbeitete Schnee etwa auf gleicher axialer Höhe ausgeworfen wird wie auf der Höhe seiner Aufnahme als noch zu bearbeitende Schneemenge. Beim Abfräsen von Schneehügeln oder Schneewellen, die etwa in der Mitte der Fräseinrichtung angeordnet sind, können die Leitelemente vorzugsweise so verstellt werden, dass der Schnee innerhalb des Fräsengehäuses von der Mitte aus vermehrt zu den Außenseiten transportiert wird.In an embodiment of the invention, the guide elements are movably arranged and adjustable by at least one adjusting device.

Preferably, the guide elements are set so that at large fresh snow amounts of snow from the outer sides of the milling device, that is, transported from the lateral areas of the at least one milling shaft toward the center. At lower, to be processed amounts of snow, the guide elements are preferably aligned so radially to the axis of rotation of the milling shaft that the processed snow is ejected at about the same axial height as at the height of its intake as still to be processed amount of snow. When milling snow hills or snow waves, which are arranged approximately in the middle of the milling device, the guide elements can preferably be adjusted so that the snow is transported within the milling housing from the center of increased to the outer sides.
