Description
Schutzvorrichtung an umlaufenden Trommeln landwirtschaft-Protective device on rotating drums agricultural
licher Arbeitsmaschinen Die Erfindung bezieht sich auf eine Schutzvorrichtung an landwirtschaftlichen Arbeitsmaschinen nach dem Gattungsbegriff des Patentanspruches 1.Licher work machines The invention relates to a protective device on agricultural machines according to the generic term of the patent claim 1.
Die Aufgabe der vorliegenden Erfindung ist es, bekannte Ausführungen dieser Art, wie sie beispielsweise in der Gebrauchsmusterschrift 1 941 878 beschrieben sind, in ihrer Schutzwirkung zu verbessern und vor allem die Vorrichtung so zu gestalten, daß mit ihr neben ihrer eigentlichen Aufgabe des Wickelschutzes eine Versteifung der beidseitigen Lagerwände einerseits in ihrer Beziehung zueinander als Gehäuse sowie andererseits jeder Lagerwand für sich zu erreichen ist.The object of the present invention is to provide known designs of this type, as described, for example, in utility model 1 941 878 are to be improved in their protective effect and, above all, to design the device in such a way that that with her, in addition to her actual task of winding protection, a stiffening the two-sided bearing walls on the one hand in their relationship to one another as a housing and on the other hand, each storage wall can be reached individually.
Erfindungsgemäß wird diese Aufgabe mit einer Ausführung nach den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst.According to the invention, this object is achieved with an embodiment according to the characterizing features Features of claim 1 solved.
Durch den labyrinthartigen Verlauf des Ringspaltes zwischen Umhüllung und Außenumfang der Trommel bzw. der Trommel zugekehrten Stirnseite des Ringflansches ist gewährleistet, daß kein langhalmiges Erntegut in den Raum zwischen Tronunel-Stirnseite und Lagerwand und somit zur umlaufenden Welle der Trommel gelangen und durch Umschlingen der Welle Betriebsstörungen verursachen kann. Des weiteren sind die Lagerwände bei hoher Belastung während des Betriebes der Arbeitsmaschine, die beispielsweise bei Verwendung der Trommeln als Fräswalzen in einer Ablade-Dosiereinrichtung eines Ladewagens gegeben ist, über die Umhüllungen an den Ringflanschen der Trommeln seitlich abgestütst, was eine wesentliche Versteifung der beideitigen Lagerwände sowohl in ihrer Beziehung zueinand r als Gehäuse als auch jeder Lagerwand fUr sich bringt.Due to the labyrinth-like course of the annular gap between the envelope and the outer circumference of the drum or the end face of the annular flange facing the drum ensures that no long-stemmed crop gets into the space between the front of the Tronunel and bearing wall and thus to the rotating shaft of the drum and by being looped around the shaft can cause malfunctions. The storage walls are also included high load during operation of the machine, for example when Use of the drums as milling drums in an unloading / dosing device of a loading wagon is given, laterally supported over the casings on the ring flanges of the drums, what a substantial stiffening of the bearing walls on both sides both in their relationship to each other as a housing as well as each bearing wall for itself.
Für einen möglichst geringen Verschleiß an den gegeneinander gerichteten und bei Belastung aufeinander gleitenden Flächen der Umhüllung und des Ringflansches kann bevorzugt eine Ausgestaltung nach den Merkmalen des Anspruches 3 vorgesehen sein.For the lowest possible wear on those facing each other and surfaces of the casing and the annular flange that slide on each other when loaded an embodiment according to the features of claim 3 can preferably be provided be.
Für einen einfachen Ein- und Ausbau der Trommeln zwischen den Lagerwinden ist es von Vorteil, wenn entsprechend Anspruch 2 die Ringflansche lösbar mit den Trommeln verbunden sind.For easy installation and removal of the drums between the bearing winches It is advantageous if, according to claim 2, the annular flanges releasably with the Drums are connected.
Im folgenden ist die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert.In the following the invention is schematically based on one in the drawing illustrated embodiment explained in more detail.
Die an ihrem Außenumfang mit Mitnehmern 1 versehene Trommel 2 die beispielsweise eine in der Ablade-Dosiereinrichtung eines Ladewagens verwendete Fräswalze ein kann, ist mit ihrer Welle 3 in Gleitlagern 4 der Lagerwange 5 drehbar gelagert und eo zwischen den Lagerwänden 5 angeordnet, daB beidseitig ein Freiraum 6 zwischen ihren Stirnseiten und den Lagerwänden 5 verbleibt.The drum 2 which is provided on its outer circumference with drivers 1 for example one used in the unloading metering device of a loading wagon Milling drum can be rotated with its shaft 3 in plain bearings 4 of the bearing cheek 5 stored and eo arranged between the bearing walls 5, that a free space on both sides 6 remains between their end faces and the bearing walls 5.
Zum Schutz der Welle 3 vor langhalmigem Erntegut sind die Freiräume 6 durch tellerförmige Umhüllungen 7 abgedeckt, die einerseits über Schraubverbindungen 8 an den Lagerwänden 5 angeschlossen sind und andererseits die Trormnelenden mit geringem Spiel umfassen. Die Trommel 2 weist stirnseitig über den Trommelumfang vorstehende Ringflansche 9 auf, die gleichfalls von den Umhüllungen 7 umfaßt und zu diesen eo angeordnet sind, daß zwischen ihren der Trommel 2 zugekehrten Stirnseiten lo und den UmhUllungen 7 Ringspalte 11 mit geringer Breite gebildet sind. Bei Belastung der Lagerwände 5 während des Betriebe der Arbeitsmaschine können sich diese über die Umhüllungen 7 seitlich an den Flanschen 9 abstützen. Für einen geringen Verschleiß an den gegeneinander gerichteten und bei Belastung aufeinander gleitenden Flächen der Umhüllungen 7 und der Ringflansche 9 sind Letztere an ihrer der Trommel 2 zugekehrten Stirnseite mit je einem RingstUck 12 aus Polyamid versehen.The clearances are to protect the shaft 3 from long-stemmed crops 6 covered by plate-shaped casings 7, the one hand via screw connections 8 are connected to the bearing walls 5 and on the other hand the drum ends with include little play. The front of the drum 2 points over the drum circumference protruding annular flanges 9, which are also comprised of the casings 7 and to these eo are arranged that between their drum 2 facing end faces lo and the envelopes 7 annular gaps 11 are formed with a small width. Under pressure the bearing walls 5 during the operation of the machine can these over support the casings 7 on the side of the flanges 9. For low wear on the surfaces facing each other and sliding on each other when loaded of the casings 7 and the annular flanges 9 are the latter on their facing the drum 2 Each face is provided with a ring piece 12 made of polyamide.
Für einen Ein- und Ausbau der Trommel 2 zwischen den Lagerwänden 5 sind die Ringflansche 9 über Verschraubungen 13 lösbar mit der Trommel 2 verbunden.For installing and removing the drum 2 between the bearing walls 5 the ring flanges 9 are detachably connected to the drum 2 via screw connections 13.
Der Antrieb der Trommel 2 erfolgt in nicht dargestellter Weise über beispielsweise ein mit der Welle 3 verbundenes Kettenrad und einer dieser zugeordneten Treibkette von einer entsprechenden Kraftquelle der Arbeitsmaschine aus.The drum 2 is driven in a manner not shown for example a chain wheel connected to the shaft 3 and one associated with it Driving chain from a corresponding power source of the work machine.
