Abstract

The cylinder (1) of the agricultural machine eg a forage harvester, has its shaft (2) pivot-mounted in friction bearings (3) on the bearing sides (4). A slight gap is left between the outer surfaces (5) of the cylinder (1) and the bearing walls (4). On the outer surfaces (5) of the cylinder (1) are spiral ridges or grooves (7) running outwards and contrary to the direction of rotation. The grooves (7) or ridges catch any pieces of harvested crop or dirt which have penetrated between the cylinder outer surfaces and the bearing wall and force them out, away from the bearing itself.

Description

schutzvorrichtung an umlaufenden Trommeln landwirtschaftsicher Arbeitsmaschinen Die Erfindung betrifft eine Vorrichtung an landwirtschaftlichen Arbeitsmaschinen zur Verhinderung des Zutritts von landwirtschaftlichem Erntegut und Schmmutzteilen zu den Wellen bzw. Lagerstellen von an Lagerwänden des Maschinengestells drehbar gelagerten frommeln. die mit ihren Stirnflächen in geringem Abstand zu den Lagerwänden umlaufen.Protective device on rotating drums for agricultural safe machines The invention relates to a device on agricultural working machines to prevent access of agricultural crops and debris rotatable to the shafts or bearing points on bearing walls of the machine frame camped pious. those with their end faces at a short distance from the bearing walls circulate.

nckannte Ausführungen verwenden, wie beispielsweise aus der DGM-Schrift 1 941 878 zu erschen, als Schutz gegen das Aufwickeln von landwirtschaftlichem Haln- un Blattgut auf den Wellen der umlaufenden frommeln ortsfest au den Lagerwänden angeordnete, die Wellen abdeckende Umhüliungen.Use the above-mentioned versions, for example from the DGM font 1 941 878 to be obtained as protection against the winding up of agricultural un sheet material on the waves of the surrounding pious stationary on the storage walls arranged, the shafts covering sheaths.

welche die frommelenden mit geringem Spiel umfassen.which include the pious with little play.

Bei diesen bekannten Ausführungen ist die Gefahr, daß langhalmiges I:a'rnteyut zu den umlaufenden Wellen gelangt und durch Umschlingen der Wellen Betriebsstörungen ver ursacht, wesentlich verringert. Es hat sich jedoch gezeigt, daß vor allem bei zähem Gras oder angewelktem Heu weiterhin Halme und kurze Erntegutteile in den Ringspalt zwischen Trommelende und Umhüllung gezogen und zur umlaufenden Welle geführt werden. Das in den Raum zwischen Trommelstirnfläche urid Lagerwand eingebrachte Erntegut kann nicht mehr entweichen und führt so nach längerer Betriebsdauer weiterhin zu Betriebsstörungen. Auch können bei den bekannten Ausführungen in den Raum zwischen rrornmelstirnfläche und Lagerwand gelangte Schmutzteile, wie Erde, Sand oder dergleichen, nicht mehr abgeführt werden, was gleichfalls Betriebsstörungen bzw. frühzeitigen Verschleiß an den Lagerstellen zur Folge hat.With these known designs there is a risk that long-lasting I: a'rnteyut gets to the circulating waves and by looping around the waves there are malfunctions caused, significantly reduced. However, it has been shown that especially with tough grass or withered hay continue to stalks and short crops in the annular gap pulled between the end of the drum and the casing and guided to the rotating shaft. The crop brought into the space between the drum face and the storage wall can no longer escape and continues to feed after a long period of operation Operational disruptions. Also in the known designs in the space between Dirt particles such as earth, sand or the like that have entered the front face and bearing wall, can no longer be discharged, which also leads to operational disruptions or premature Wear at the bearing points.

Die Erfindung bezweckt somit eine gegendber den bekannten Konstruktionen verbesserte Ausführung, die bei gleichzeitig vereinfachter Bauweise ein Freihalten der Wellen und Lagerstollen von Erntegut und Schmutzteilen gewährleistet und somit Betriebsstörungen durch Verstopfen im Raum zwischen :prorMelstirnfiäche und Lagerwand bzw. frühzeitigen Verschleiß den den Lagerstellen verhindert.The invention thus aims at a counter to the known constructions Improved design that keeps a clear structure while at the same time being simplified of the shafts and bearing tunnels of crop and debris is guaranteed and thus Malfunctions due to clogging in the space between: the front face of the proM and the bearing wall or premature wear prevents the bearing points.

tn.ä(\ der Erfindung wird diese Aufgabe dadurch gelöst, daß an den stinnflächen der Trommeln spiralfÉ8rmig entgegen Drehrr'chtuns nach außen verlaufende Rippen dcr Nuten angebracht sind. Bei Ausführungen nach diesem Vorszhlag werca.en die in den Spalt zwischen Trommelstirnfläche und £,agerwand gelangten Erntegut- und Schmutzteile vor ihrem Eindringen bis zur Welle bzw. zu den Lagerstellen durch die als Förderelemente wirkenden Rippen oder Buten an der Trommelstinnfläche während des Umlaufes der Trommel ständig zwangslänfig nach außen abgeführt Umwicklungen der Welle durch zugeführt Ernteguthalme, Verstopfungen im Raum zwischen Trommelstinnfläche und Lagerwand bzw. Zerstörung der Lagerstellen durch eingebrachte Erntegut- und Schmutzteile sind nicht rhr möglich.tn.ä (\ of the invention, this object is achieved in that the The inner surfaces of the drums spiral outwards against the direction of rotation Ribs of the grooves are attached. For versions according to this pre-payment, werca.en the crop that got into the gap between the drum face and the agerwand and dirt particles through to the shaft or the bearings before they penetrate the ribs or butes acting as conveying elements on the inner drum surface during of the rotation of the drum constantly inevitably carried away wraps The shaft is fed by harvest stalks, blockages in the space between the inner drum surface and storage wall or destruction of storage locations by harvested crops and Dirt parts are not possible.

Die mit der Erfindung gestellte Aufgabe wird in gleicher Weise auch gelöst, wenn die Lagerwände in ihrem den (in diesem Fall glatt ausgeführten) Stirnflächen der Trommeln zuliegenden Bereich spiralförmig in Drehrichtung der Trommeln von der Drehachse nach außen verlaufende Rippen oder Nuten aufweisen.The object set with the invention is also achieved in the same way solved when the bearing walls in their (in this case smooth) end faces the area lying next to the drums spirally in the direction of rotation of the drums from the Have outwardly extending ribs or grooves.

Aus der Zeichnung ist ein Ausführungsbeispiel der Erfindung in teilweise schematischer Darstellung zu ersehen. Es zeigen Fig. 1 die Anordnung an einer 2-seitig gelagerten Trommel in Schnittdarstellung und Fig. 2 eine Ansicht nach der Linie X - X der Fig. 1 Die Trommel 1, die beispielsweise eine im Zuführgchäuse einer Häckselmaschine angeordnete Vorschubwalze sein kann, ist mit ihrer Welle 2 in Gieitlacjern 3 der Lagerwände 4 drehbar gelagert und so zwischen den Lagerwänden 4 angeordnet, daß nur ein geringer Spalt zwischen Ihrrn Stirnflächen 5 und den Lagcrwänden 4 verbleibt.From the drawing, an embodiment of the invention is in part schematic representation can be seen. 1 shows the arrangement on a 2-sided mounted drum in sectional view and FIG. 2 is a view along the line X - X of FIG. 1 The drum 1, for example one in the feeder housing can be a feed roller arranged in a chopping machine, with its shaft 2 rotatably mounted in Gieitlacjern 3 of the bearing walls 4 and so between the bearing walls 4 arranged that only a small gap between your end faces 5 and the bearing walls 4 remains.

Die Stirnflächen 5 der Trommel 1 weisen spiralförmig entgegen Drehrichtung 6 nach außen verlaufende Rippen oder Nuten 7 auf, die als Förderelemente wirdend die in den Raum zwischen der Stirnfläche 5 der Trommel 3 und der Lagerwand 4 gelangten Erntegut- und Schmutzteile vor deren Eindringen bis zur Lagerstelle 3 zwangsläufig nach außen abführen.The end faces 5 of the drum 1 point in a spiral against the direction of rotation 6 outwardly extending ribs or grooves 7, which are used as conveyor elements which got into the space between the end face 5 of the drum 3 and the bearing wall 4 Crop and dirt parts inevitably before they penetrate to storage point 3 discharge to the outside.

J»r Antrieh der Trommel 1 erfolgt in nicht dargestellter Weise über beispielsweise eine Keilrdemenscheibe und Keilriemen, von einer entsprechenden Kraftquelle der Arbeitsmaschine aus.The drum 1 is driven in a manner not shown for example a pulley and belt, from an appropriate power source the working machine.
