Description

Gegenstand vorliegender Erfindung ist ein Saatzudeckzahn mit auswechselbarer Spitze und besteht das Neue hauptsächlich darin, daß die auswechselbare Spitze an ihrem Rükken einen Steuerzapfen besitzt, der durch ein in dem Zahn befindliches Loch geht.The subject of the present invention is a seed cover tooth with a replaceable tip and the novelty consists mainly in that the interchangeable tip on her back has a control pin which goes through a hole in the tooth.

Eine Ausführungsfonn des Erfindungsgegenstandes ist auf der Zeichnung dargestellt. Hierbei zeigt:One embodiment of the subject matter of the invention is shown in the drawing. Here shows:

ίο Abb. ι eine Seitenansicht eines federnden Zahnes mit auswechselbarer Spitze, teilweise im Schnitt,ίο Fig. ι a side view of a resilient Tooth with replaceable tip, partly in section,

Abb. 2 denselben in Vorderansicht und
Abb. 3 eine Einzelheit in schaubildlicher Darstellung.
Fig. 2 the same in front view and
Fig. 3 a detail in a graphical representation.

In der gezeigten Ausführungsform ist an der auswechselbaren Spitze α oberhalb das Loch b angebracht, vermittels dessen die Spitze am Zahn angeordnet wird. Am Rükken der Spitze ist ein Zapfen c vorgesehen, der nach hinten zu und nach aufwärts hakenförmig ausgebildet ist.In the embodiment shown, the replaceable tip α has the hole b above it, by means of which the tip is arranged on the tooth. On the back of the tip there is a pin c which is hook-shaped towards the rear and towards the top.

Am Federzahn d ist oberhalb des Bolzenloches e, durch welches ein Bolzen f in beß5 kannter Weise die Spitze α festhält, ein Loch g vorgesehen, das schräg nach oben durch den Zahn α geht und eine nach vorn hervorstehende Wölbung h am Zahn bildet.On the spring tooth d , a hole g is provided above the bolt hole e through which a bolt f holds the point α in a known manner, which goes obliquely upward through the tooth α and forms a protruding arch h on the tooth.

Der hakenförmige Zapfen c wird in das Loch g gesteckt und geht durch dasselbe hindurch unter die Wölbung h, die sich an den Rücken der Spitze schließt. Erst dann wird der Bolzen / durch die Löcher b und e gesteckt und hierdurch die Spitze am Zahn d festgespannt. Die auswechselbare Spitze wird in dieser Weise derart festsitzen, daß sie nirgends sich lösen kann, da der Arbeitsdruck gegen die Spitze, ohne den Spannbolzen zu beeinträchtigen, direkt auf den Zahn über-The hook-shaped pin c is inserted into the hole g and goes through the same under the bulge h, which closes on the back of the tip. Only then is the bolt / inserted through the holes b and e and thereby the tip is clamped to the tooth d. In this way, the replaceable tip is so tight that it cannot loosen anywhere, as the working pressure against the tip, without affecting the clamping bolt, is transferred directly to the tooth.

Claims (1)

Patentanspruch:Claim: tragen wird, während der entgegengesetzt gerichtete Druck (vom Zahn d weg) am oberen Ende der Spitze durch den hakenförmigen Zapfen auf die Wölbung h des Zahnes d wirkt und somit ebenfalls direkt von der Spitze auf den Zahn übertragen wird, ohne den Spannbolzen/ zu beeinflussen.while the opposite pressure ( away from tooth d ) at the upper end of the tip acts through the hook-shaped pin on the arch h of tooth d and is thus also transmitted directly from the tip to the tooth without affecting the clamping bolt / . Die Spitze α kann sich infolgedessen nicht lösen oder am Zahn lockern, selbst nicht bei allergrößter Beanspruchung; gleichzeitig wird jedoch erreicht, daß die Spitze sehr leicht auswechselbar ist, indem man nur den Spannbolzen / zu lösen braucht, um die Spitze abnehmen zu können.As a result, the tip α cannot loosen or loosen on the tooth, even under the greatest stress; At the same time, however, it is achieved that the tip can be exchanged very easily by only needing to loosen the clamping bolt / in order to be able to remove the tip. Die Zapfenanordnung der Spitze α und Lochanordnung am Zahn d ist hierbei sehr leicht herzustellen, indem der Zapfen c aus dem Material der Spitze geschmiedet oder gepreßt oder aufgeschweißt werden kann, während das Loch g und die Wölbung h derart im Zahn d hergestellt werden kann, daß ein Dorn durch die angeglühte Spitze gestoßen und der Dorn hiernach um etwa 60° zum Zahn geneigt wird, wodurch die Wölbung h gebildet wird, und das Lochg die richtige schräge Lage im Zahn erhält.The pin arrangement of the tip α and the hole arrangement on the tooth d is very easy to produce in that the pin c can be forged or pressed or welded on from the material of the tip, while the hole g and the bulge h can be made in the tooth d in such a way that a mandrel pushed through the annealed tip and the mandrel is then inclined by about 60 ° to the tooth, whereby the curvature h is formed and the hole g is given the correct inclined position in the tooth.
