Description
Die Erfindung betrifft ein umlaufendes, federnd angeordnetes Werkzeug für Bodenbearbeitungsmaschinen und besteht darin, daß der Arbeitshaken unter Vermittlung eines Exzenters auf der Fräswelle derart drehbar gelagert ist, daß er beim Auftreten von Widerständen unter Überwindung der Federkraft in an sich bekannter Weise nach rückwärts und einwärts ausweichen kann. ίο Auf der Zeichnung ist in Abb. ι und 2 ι die Fräswelle, 2 die auf der Fräswelle befestigte Exzenters cheibe und 3 der Exzenterring. Mit dem Exzenterring ist der Arbeitshaken 4 auswechselbar verbunden. Zu beiden Seiten des Exzenters sind spiralförmig gewundene Federn 5 angeordnet, deren Enden einerseits an dem Exzenterring und andererseits in der Nähe der Fräswelle, beispielsweise an der verlängerten Nabe des Exzenters, fest ao eingespannt sind. Der Exzenterring ist so breit gehalten, daß er die Federn überdeckt, und an den Seiten ist er durch Scheiben 6 abgedeckt. Dadurch sind Exzenter und Federn gut !eingebaut und gegen Verunreinigungen und Beschädigungen geschützt. Exzenter und Federn lassen sich in einem kleinen Raum nahe der Fräswelle unterbringen, so daß keine Teile in die von den Haken bearbeiteten1 Bodenmassen 'eindringen können. Man kann mehrere solcher aus Exzenter, Federn und Arbeitshaken bestehende Einheiten auf der Fräswelle nebeneinander und im Bedarfsfall versetzt gegeneinander anordnen, je nach der gewünschten Arbeitsbreite. Beim Auftreten eines Widerstandes an der Spitze des Arbeitshakens dreht sich der Haken mit Exzenterring auf dem Exzenter in der Weise, daß die Entfernung der Hakenspitze von der Fräswelle kleiner wird; dadurch kannThe invention relates to a rotating, resiliently arranged tool for soil cultivation machines and consists in the fact that the working hook is rotatably mounted on the milling shaft by means of an eccentric so that when resistances occur, it deflects backwards and inwards in a manner known per se, overcoming the spring force can. ίο In the drawing in Fig. ι and 2 ι the milling shaft, 2 the eccentric disk attached to the milling shaft and 3 the eccentric ring. The working hook 4 is interchangeably connected to the eccentric ring. Spirally wound springs 5 are arranged on both sides of the eccentric, the ends of which are firmly ao clamped on the one hand on the eccentric ring and on the other hand in the vicinity of the milling shaft, for example on the extended hub of the eccentric. The eccentric ring is kept so wide that it covers the springs, and it is covered by washers 6 on the sides. This means that the eccentric and springs are well installed and protected against contamination and damage. Eccentric and springs can be accommodated in a small space close to the auger shaft, so that no parts can penetrate into the machined from the hooks 1 soil masses'. You can arrange several such units consisting of eccentrics, springs and working hooks on the milling shaft next to one another and, if necessary, offset from one another, depending on the desired working width. When a resistance occurs at the tip of the working hook, the hook with the eccentric ring rotates on the eccentric in such a way that the distance between the tip of the hook and the milling shaft becomes smaller; thereby can
der Arbeitshaken Widerständen ausweichen und leichter über sie hinweggleiten. Während dieses Ausweichens werden die Federn gespannt, und nach Aufhören des Widerstandes bringen sie den Arbeitshaken in seine ursprüngliche Lage zurück.the working hook evade resistance and slide over it more easily. While this evasive action the springs are tightened, and after the resistance has ceased return the working hook to its original position.
Der Exzenterring 3 kann aus einem Rohrstück bestehen und auf dem auf seinem Umfang eine Nut 7 enthaltenden Exzenter durch Schrauben 8 geführt sein, deren Enden in die Nut 7 eingreifen. Infolgedessen ist es nicht nötig, den Exzenterring zweiteilig herzustellen; außerdem wird an Dreharbeit gespart. The eccentric ring 3 can consist of a piece of pipe and on its circumference an eccentric containing a groove 7 can be guided by screws 8, the ends of which engage in the groove 7. As a result it is not necessary to produce the eccentric ring in two parts; it also saves on filming.
