Description
Die Erfindung betrifft eine insbesondere für Dreschmaschinen bestimmte Strohzerkleinerungsvorrichtung mit einer in einem ortsfesten Korb umlaufenden Zerkleinerungstrommel und mit Messern, die von in der Trommel und außerhalb des Korbes liegenden Haltern getragen werden, wobei als Messerhalter die Speichen der Trommel oder besondere Halterstücke verwendet werden.The invention relates to a straw chopping device particularly intended for threshing machines with a shredding drum rotating in a stationary basket and with knives that are in the Drum and holders lying outside the basket are carried, with the spokes of the drum or as knife holders special holder pieces are used.
Bei den bekannten Zerkleinerungsvorrichtungen dieser Art liegen die Messer in Reihen senkrecht zur Drehachse der Trommel. Es hat sich gezeigt, daß die Messer bei einer solchen Anordnung ungleich beansprucht werden und zwecks Gewinnens einer kurzen Schnittlänge an der Trommel und am Korb gedrängt nebeneinander angeordnet werden müssen, so daß die Messer, besonders aber deren Tnäger, schwer zugänglich sind, weil jedem Messer ein besonderer Träger zugeordnet werden muß.In the known comminuting devices of this type, the knives are arranged in rows perpendicular to the axis of rotation of the drum. It has been shown that the knives in a such an arrangement are unequally stressed and in order to gain a short one Cutting length on the drum and on the basket are juxtaposed must, so that the knives, but especially their hangers, are difficult to access because a special carrier must be assigned to each knife.
Um diesen Nachteil zu beseitigen, werden gemäß der Erfindung Messerhalter verwendet, die aus .an jedem Steg ein Messer tragenden U-Eisen bestehen, deren Steg die Form eines Parallelogrammsi hat. Diese Ausbildung der Messer ermöglicht es, an jedem Messerträger zwei Messer zu befestigen und bei entsprechender Formgebung der Messerhalter die Messer an der Trommel und am Korb schraubenförmig anzuordnen, wodurch die gleichmäßige Beanspruchung sämtlicher Messer gesichert ist.In order to eliminate this disadvantage, knife holders are used according to the invention, which consist of .At each web a knife-carrying U-iron, whose web the Has the shape of a parallelogram. This training of the knife makes it possible to to attach two knives to each knife carrier and with the appropriate shape of the Knife holder to arrange the knives on the drum and on the basket in a helical manner, whereby the uniform stress all knives are secured.
Eine Ausführungsform der Erfindung ist auf der Zeichnung veranschaulicht.An embodiment of the invention is illustrated in the drawing.

11 ist der Mantel der Zerkleinerungstrommel und 12 der Mantel des diese achsgleich umgebenden ortsfesten Korbes. Im Mantel'11 der Trommel sind Schlitze 13 und im Mantel 12 des Korbes Schlitze 14 vorgesehen. Durch die Schlitze greifen die Messer 15, von denen je zwei von einem U-föirmigen Messerhalter 16 getragen werden, der mit seinem Steg auf der Innenseite der Trommel 11 bzw. auf der Außenseite des Korbes 12 durch Nieten oder Schrauben 18 befestigt ist. Die die Messer tragenden Schenkel 1711 is the jacket of the shredding drum and 12 is the jacket of this on the same axis surrounding stationary basket. In the jacket 11 of the drum are slots 13 and Slits 14 are provided in the jacket 12 of the basket. The knives reach through the slots 15, of which two each by a U-shaped Knife holder 16 are carried with its web on the inside of the drum 11 or attached to the outside of the basket 12 by rivets or screws 18 is. The legs 17 carrying the knives
