Description

Bodenfräser, bei denen die Werkzeuge anGround milling cutters where the tools are attached

aus Blattfedern bestehenden, elastischen Stielen angeordnet sind, welche durch Schwungkraft in die Erde getrieben werden, sind bekannt.consisting of leaf springs, elastic stems are arranged, which by Inertia are driven into the earth, are known.

Die Erfindung betrifft einen Bodenfräser mit ebenfalls elastischen Werkzeugträgern, welche gegenüber den bekannten den Vorteil der größern Festigkeit und genauen Anpassungsfähigkeit an die jeweiligen Bodenverhältnisse aufweisen und gleichzeitig eine billigere Herstellung ermöglichen.The invention relates to a ground milling cutter with also elastic tool carriers, which over the known the advantage of greater strength and precise adaptability have to the respective soil conditions and at the same time enable cheaper production.

Das Neue der Erfindung besteht darin, daß die Werkzeugträger aus paarweise miteinander verbundenen nachgiebigen Organen bestehen.The novelty of the invention is that the tool carriers are made in pairs with one another associated compliant organs exist.

In der Zeichnung sind in den Abb. 1 und 2 bzw. 3a und 3b zwei Ausführungsbeispiele von solchen Werkzeugträgern dargestellt.In the drawing, two exemplary embodiments are shown in FIGS. 1 and 2 or 3a and 3b represented by such tool carriers.

So besteht mach Abb. 1 und 2 der Kern der in bekannter Weise auf der umlaufenden Trommel b befestigten, Werkzeugträger aus einem Draht- oder Hanfseil c, um welches auf die ganze Länge eine Schraubenfeder h gewickelt ist. Am freien Ende des Seiles c ist das Werkzeuge? befestigt. Außerdem kann über die Feder h noch eine Lederhülse e übergezogen sein, welche die erstere vor Beschädigung schützt.Thus, mach Fig. 1 and 2, the core of the tool carrier, which is fastened in a known manner on the rotating drum b , consists of a wire or hemp rope c, around which a helical spring h is wound over the entire length. At the free end of the rope c is the tool? attached. In addition, a leather sleeve e can be pulled over the spring h , which protects the former from damage.

Im Beispiel nach Abb. 3a und 3b besteht der Werkzeugträger aus einer Kette? und Blattfedern m, welche die das Werkzeug d tragende Kette I im Ruhezustand gestreckt hält. Der Hauptwert der Erfindung besteht darini, daß die Hauptbeanspruchung beim Arbeiten des Fräsers von· einem äußerst stabilen, starken Organ, also dem Kern c aufgenommen wird, während die Hilfsorgane h3 e dem Hauptorgan die zum Arbeiten und für den Ruhezustand erforderliche Steifigkeit verleihen und1 als Führung des letzteren dienen. Auch wird erreicht, daß der Werkzeugträger mit Bezug auf seine Biegsamkeit genau dem zu bearbeitenden Boden angepaßt werden kann. Abb. 4 läßt die Arbeitsweise von solchen Werkzeugträgerm erkennen, insbesondere das Durchbiegen desselben und das senkrechte Angreifen des Werkzeuges d. In the example according to Fig. 3a and 3b, the tool carrier consists of a chain? and leaf springs m, which keep the chain I carrying the tool d stretched in the resting state. The main value of the invention is that the main stress when the milling cutter is working is absorbed by an extremely stable, strong organ, i.e. the core c , while the auxiliary organs h 3 e give the main organ the rigidity required for working and for the state of rest and 1 serve as the guide of the latter. It is also achieved that the tool carrier can be precisely adapted to the soil to be worked with regard to its flexibility. Fig. 4 shows the working of such tool carriers, in particular the bending of the same and the vertical gripping of the tool d.
