Jedes Flügelrad 12, 14 weist eine zentrale, rotationssymmetrisch zur Drehachse y angeordnete und mit dieser einen Winkel von etwa 45° einschliessende konische Leitfläche 20 auf. Von der konischen Leitfläche 20 ragen gleichmässig über den Umfang verteilte Leitflügel 22 radial nach aussen ab. Die Projektion der Leitflügel 22 in Radialrichtung schneidet dabei die Drehachse y in einem spitzen Winkel von etwa 45°, d.h., die Fläche der Leitflügel 22 ist gegenüber einer von der Drehachse y ausgehenden Radialebene um einen Winkel von etwa 45° verdreht. Die Leitflügel 22 erstrecken sich über die gesamte Breite der konischen Leitfläche 20 und sind durch zwei parallel zueinander und rechtwinklig zur Drehachse y stehende seitliche Flügelränder 24, 26 begrenzt.

Der durch die Flügelabdeckung 34 gebildete Führungskanal gibt die Leitflügel 22 oberhalb des Förderbandes 18 frei, was folgende Vorteile hat:
- Sperriges Material wie Holz, Seile, Kabel usw., das sich in
den Leitflügeln 22 verfangen hat, kann nach dem Stoppen des Flügelrades 12, 14 problemlos entfernt werden. Die Leitflügel 22 können automatisch bei laufendem Flügelrad 12, 14 oder manuell bei stehendem Flügelrad 12, 14 beispielsweise von hartnäckig klebrigem Material wie Lehm, Seekreide usw. gereinigt werden

Weil es keine permanente geschlossene Hohlräume gibt, wie z.B. Becher mit Boden, ist dieses Aushubsystem ebenfalls sehr geeignet für problematisches Aushubgut, wie nasser Humus, Lehm, Seekreide usw.Because there are no permanent closed cavities, such as Cup with bottom, this excavation system is also very suitable for problematic excavated material, such as wet humus, clay, sea chalk, etc.
Das Flügelrad 12, 14 ist sehr kompakt und ohne exponierte, bewegliche Teile, wie z.B. Ketten, Becher usw. Dadurch kann es so robust gebaut werden, dass vorkommende grössere Broken wie Mauerwerk, Steine usw. problemlos zerkleinert werden. Blockiert ein Gegenstand das Flügelrad 12, 14, so schützt eine automatische Druckabschaltung die Einrichtung vor Deformationen. Wird festgestellt, dass z.B. ein Kabel erfasst und aufgewickelt wird, so kann die Drehbewegung sofort gestoppt und die Verwicklung durch Ändern des Drehsinns behoben werden. Die beiden Flügelräder 12, 14 sind einzeln über je einen Motor 40 angetrieben und auch einzeln steuerbar.The
Die am äusseren seitlichen Rand 26 der Leitflügel 22 montierten Flügelzähne 28 dienen zur Lockerung von hartem Aushubmaterial 41.The
Je nach Anwendungsbereich gibt es für das Flügelrad 12, 14 verschiedene Optimierungsvarianten:
- Bei Änderung der Drehrichtung u kann die Arbeitsrichtung A geändert werden (rückwärts, schwenken). Ebenso ist eine Anpassung an Schichtungen des Aushubmaterials möglich.
Oben geschlossene Leitflügel 22mit abgewinkeltem Flügelteil 38 anstelle der Flügelabdeckung 34 sind besonders geeignet für körniges Aushubgut ohne Sperrgut, wie z.B. Holz.- Eine im Aushubbereich durchgehende Flügelabdeckung 34 (
Fig. 12 ) ist besonders geeignet für problematisches Aushubgut, wie grosse Steine und Holz. Sperrgut wird ausgeschieden. Diese Anordnung funktioniert beim Schwenken, nicht jedoch bei Vorwärts- und Rückwärtsfahrt. - Ein im Aushubbereich durchgehendes Leitschild 30 (
Fig.13 ) ist besonders geeignet für Sperrgut, das nicht zerkleinert werden kann, wie z.B. Granitklötze und armierte Fundamentrückstände. - Ein gekürztes Leitschild 30 (
Fig.14 ) ist besonders geeignet für zerkleinerbares Sperrgut, wie z.B. Backsteine.
- When changing the direction of rotation u, the working direction A can be changed (backward, pivoting). Likewise, adaptation to stratifications of the excavated material is possible.
- Top
closed guide vanes 22 withangled wing portion 38 instead of thewing cover 34 are particularly suitable for granular Aushubgut without bulky goods, such as wood. - A
wing cover 34 passing through in the excavation area (FIG.Fig. 12 ) is particularly suitable for problematic excavated material, such as large stones and wood. Bulky goods are eliminated. This arrangement works when panning, but not during forward and reverse. - An in the excavation area continuous guide plate 30 (
Figure 13 ) is particularly suitable for bulky goods that can not be crushed, such as granite blocks and reinforced foundation residues. - A shortened signage 30 (
Figure 14 ) is particularly suitable for shredding bulky items such as bricks.
