Abstract

Ice blocks are shaved down or milled, using a high speed rotary blade shaft (d). A layer optionally about 1/10 mm thick is shaved off. Ice chippings produced, are in the form of powdery snow. The shaft (d) is constructed with paring blades. The blades take the form of rows of teeth. The rows are spaced apart and offset for slight overlap of the cutting faces of the teeth. An additional blower unit, with air outlet pipes (j) and fans or driven nozzles (k), are fitted ahead of the air outlet slots. The equipment blows the snow flakes as high as possible into the air, causing air moisture crystallization. In this way, the quantity of snow produced is increased. The equipment is dimensioned for fitting before or after known types of snow cannons.

Description

Die Erfindung betrifft eine fahrbare Schneeerzeugungsmaschine zur Gewinnung von Schnee aus Eisblöcken zur Beschneiung von Skipisten, wobei die Eisblöcke zerkleinert werden.The The invention relates to a mobile snow-making machine for extraction of snow from blocks of ice for snowmaking of ski slopes, whereby the ice blocks are crushed.

Die Durchschnittstemperaturen auf der Erde sind in den vergangenen Jahren kontinuierlich angestiegen. Durch diese Tatsache werden die Winter milder. Der Schneefall setzt meist später und auch in geringerem Umfang ein. Die Schneesicherheit der Skipisten hat sich somit erheblich verschlechtert. Insbesondere im Mittelgebirgsraum und in den tieferen Lagen der Alpenregionen ist die Schneesicherheit zum Teil nur unter Einsatz von künstlicher Beschneiung gewährleistet.The Average temperatures on Earth have been in recent years continuously increased. This fact turns the winters milder. The snowfall sets mostly later and in less Scope. The snow reliability of the ski slopes has thus considerably deteriorated. In particular, in the low mountain area and in the lower Locations of the Alpine regions are partly under snow Use of artificial Snowmaking guaranteed.

Zur künstlichen Beschneiung werden in den letzten Jahren mehr und mehr so genannte Schneekanonen eingesetzt. Dieser Einsatz erfordert einen sehr hohen Wasser- und Stromverbrauch, die durch kostspielige Anlagen sichergestellt werden müssen. Außerdem können Schneekanonen nur bei Minusgraden eingesetzt werden.to artificial Snowmaking is becoming more and more so called in recent years Used snow cannons. This use requires a very high Water and electricity consumption ensured by costly equipment Need to become. In addition, snow cannons only be used at temperatures below freezing.

Die EP 399 946 A1 zeigt als Alternative eine fahrbare Schneeerzeugungsmaschine. Dort werden Eisblöcke durch Messerwellen zerkratzt, wodurch aber sehr kleine Eispartikel entstehen.The EP 399 946 A1 shows as an alternative a mobile snow-making machine. There, ice blocks are scratched by knife shafts, which causes very small ice particles.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Schneeerzeugungsmaschine anzugeben, die einen niedrigen Wasser- und Stromverbrauch aufweist, bei Temperaturen über Null Grad arbeiten kann und qualitativ hochwertigen Schnee liefert, der dem Naturschnee sehr ähnlich ist.Of the The invention is therefore based on the object, a snow-making machine which has a low water and electricity consumption, at temperatures above Can work zero degrees and delivers high quality snow, very similar to natural snow is.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruchs gelöst.These The object is achieved by the Features of the main claim solved.

Für die benötigten Eisblöcke in einer Größe von z.B. 2,00 × 3,00 m und einer Stärke von 1,00 m kann das benötigte Wasser in Hochlagen des Gebirges im Sommer oder Herbst aufgefangen und in vorbereitete Formen oder flache Teiche geleitet werden. Bei einsetzendem Frost gefriert das Wasser auf natürlichem – oder auch auf künstlichem – Wege zu festen Eisblöcken, die so transportiert und bearbeitet werden können.For the required ice blocks in one Size of e.g. 2.00 × 3.00 m and a strength from 1.00 m can the needed Water collected in high altitudes of the mountains in summer or autumn and be directed into prepared shapes or shallow ponds. at the frost freezes the water in natural - or artificial - ways to solid ice blocks, which can be transported and processed.

Wenn man Eis dünnschichtig abhobelt oder abfräst, entsteht aus den abgetrennten Eispartikeln Pulverschnee. Diese Eisblöcke werden daher durch die fahrbare Schneeerzeugungsmaschine ähnlich einem Dicken-Hobel durch hochtourige Messerwellen abgehobelt bzw. abgefräst.If you ice thinly plane or milled off, arises from the separated ice particles powder snow. These ice blocks will be therefore by the mobile snow-making machine similar to one Thick plane planed by high-speed knife shafts or milled off.

Die Anlage kann elektronisch so gesteuert werden, dass die Messerwelle Eisspäne in einer Stärke von ca 1/10 mm abhobelt. Der gewonnene Pulverschnee wird dann durch eine Gebläseeinrichtung auf die Piste geblasen.The Plant can be electronically controlled so that the knife shaft ice chips in a strength planed off from about 1/10 mm. The recovered powder snow is then through a blower device blown on the slopes.

Die erfindungsgemäße fahrbare Schneeerzeugungsmaschine kann als selbsttätige, mit Verbrennungsmotoren angetriebene Maschine oder als Hänger an Pistenwalzen eingesetzt werden. Besondere Wasser- und Stromanschlüsse sind nicht erforderlich.The movable according to the invention Snow making machine can be used as an automatic, with internal combustion engines powered machine or as a trailer be used on piste rollers. Special water and electricity connections are not mandatory.

Weitere Vorteile der vorliegenden Erfindung ergeben sich aus der folgenden Beschreibung mehrerer Ausführungsbeispiele sowie aus den Zeichnungen auf die nun Bezug genommen wird.Further Advantages of the present invention will become apparent from the following Description of several embodiments and from the drawings to which reference is now made.

In den Abbildungen A und B ist das System einer fahrbaren Schneeerzeugungsmaschine zur Gewinnung von Schnee aus Eisblöcken dargestellt. Es besteht aus dem Fahrgestell a mit Rädern b, hinteren Luftschlitzen c, der horizontal beweglichen Messerwelle d, Messerblättern e, dem Antriebsmotor f, dem Hubboden g, dem Gebläse h und dem Eisblock i.In Figures A and B is the system of a mobile snow-making machine presented for the extraction of snow from ice blocks. It exists from the chassis a with wheels b, rear louvers c, the horizontal movable blade shaft d, knife blades e, the drive motor f, the lifting base g, the blower h and the ice block i.

In der Abbildung C ist eine Alternative zu Schälmessern dargestellt. Die Messerwelle hat eine größere Länge als die Breite der Eisblöcke und ist mit gezähnten Messerblättern ausgestattet. Bei diesen Messerblättern sind jeweils zwei so aufeinander abgestimmt, dass sich die Schnittflächen geringfügig überlappen.In Figure C shows an alternative to peeling knives. The knife shaft has a longer length than the width of the ice blocks and is serrated cutter blades fitted. There are two each for these knife blades coordinated so that the cut surfaces overlap slightly.

Um die Schneeausbeute der fahrbaren Schneeerzeugungsmaschine zu erhöhen, können vor den Entflütungsschlitzen (c) ein- oder zweirohrige Abluftgebläse an Lagern angebracht werden.Around To increase the snow yield of the mobile snow-making machine can before the escape slots (c) one or two pipe exhaust fans are mounted on bearings.

Über die ca 5–10 Meter hohen oder höheren ca 30 cm ϕ starken Abluftrohre (j) werden die abgehobelten Schneeflocken möglichst hoch in die Luft geblasen.About the about 5-10 Meter high or higher approx 30 cm φ strong exhaust pipes (j) are the planed Snowflakes as possible blown high in the air.

Bei diesem Vorgang nehmen die dann wieder zur Erde rieselnden Schneeflocken Luftfeuchtigkeit auf, kristallisieren mit dieser und vergrößern dadurch die erzeugte Schneemenge.at This process takes the then trickling down to earth snowflakes Humidity, crystallize with this and thereby enlarge the amount of snow generated.

Durch den Einbau von zusätzlichen Ventilatoren oder Antriebsdüsen (k) in den Abflussgebläserohren (j) kann dieser Effekt beschleunigt, bzw. erhöht werden.By the installation of additional Fans or drive nozzles (k) in the drainage blower pipes (j) this effect can be accelerated or increased.
