Description

Beim Betrieb von Maschinen zur Herstellung unterirdischer Kanäle zeigt es sich, daß der im Querschnitt kreisförmige Treibdorn nicht immer in der eingestellten Höhenlage bleibt. Bei sumpfigem Boden wird er von dem Gewicht der Maschine tiefer gedrückt, und bei schwerem Boden kommt es vor, daß der Treibdorn sich hebt. Um diesen Übelstand zu vermeiden, ist der Treibdorn gemäß der Erfin dung in seiner waagerechten Mittel ebene mit Leitflügeln versehen, die die Auflagefläche erhöhen, wodurch dann ohne weiteres ein genaues Arbeiten erzielt wird. Die Anzahl, Form und Größe der Leitflügel richtet sich nach den jeweiligen Bodenverhältnissen und nach dem Zweck, dem der zu erzeugende Kanal dienen soll.In the operation of machines for the production of underground channels, it turns out that the driving mandrel, which is circular in cross-section, is not always at the set altitude remain. If the ground is swampy, the weight of the machine pushes it deeper, and at heavy soil, it happens that the drift spike rises. To this evil too avoid, the drift pin according to the inven tion in its horizontal central plane provided with guide vanes that increase the contact surface, which then easily makes an accurate Work is achieved. The number, shape and size of the guide vanes depends on the respective soil conditions and according to the purpose for which the channel to be generated is to serve.

Auf der Zeichnung ist ein Ausführungsbeispiel des Treibdornes in der Abb. 1 in Seitenansicht und in der Abb. 2 im Querschnitt veranschaulicht, während die Abb. 3 die Oberansicht zeigt. In der Abb. 4 ist ein Dorn in Oberansicht dargestellt, bei dem nur der hintere Teil mit Leitflügeln besetzt ist.In the drawing, an embodiment of the driving mandrel in Fig. 1 is in side view and in Fig. 2 in cross section, while Fig. 3 is a top view shows. In Fig. 4 a mandrel is shown in top view, in which only the rear part is occupied with guide vanes.

An einem Schneidemesser α ist unten der Treibdorn & drehbar oder starr befestigt. Bei einem verhältnismäßig breiten Messer wird auch die Seitenrichtung zuverlässig innegehalten. Damit der Dorn aber die eingestellte Höhenlage nicht verläßt, ist er mit zwei waagerecht liegenden Leitflügeln c versehen, aber es können im Bedarfsfalle auch noch zwei weitere dazu senkrecht stehende Flügel zur Anwendung kommen. Die Flügel können über die ganze Länge des Treibdornes reichen, wie es in der Abb. 3 mit strichpunktierten Linien veranschaulicht ist, oder es wird nur der vordere oder der hintere Teil des Dornes mit Leitflächen ausgestattet.The driving mandrel & is rotatably or rigidly attached to a cutting knife α at the bottom. With a relatively wide knife, the lateral direction is also reliably paused. So that the mandrel does not leave the set altitude, it is provided with two horizontally positioned guide vanes c , but if necessary two further vanes that are perpendicular to them can also be used. The wings can extend over the entire length of the driving mandrel, as illustrated in Fig. 3 with dash-dotted lines, or only the front or the rear part of the mandrel is equipped with guide surfaces.

Besonders wenn es sich um Treibdorne handelt, deren Messer α an einem frei schwingenden Ausleger sitzt, erweisen sich diese Leitflügel sehr vorteilhaft, denn sowohl bei Drainagearbeiten als auch beim Kabeleinzug ist es wichtig, stets die eingestellte Tiefe oder das Gefälle genau innezuhalten.These guide vanes prove to be very advantageous, especially when it comes to driving mandrels, the knife α of which sits on a freely swinging boom, because it is important to always keep the set depth or slope exactly during drainage work as well as when pulling in cables.

Hinsichtlich der praktischen Ausführung bzw. Befestigung der Flügel sind verschiedene Möglichkeiten gegeben, entweder die Teile werden starr miteinander verbunden, z.B. verschweißt, oder die Flügel werden in Schlitze des Dornes eingelassen und durch Schrauben oder Keile befestigt, so daß sie bei Bedarf auch entfernt werden können. Diese auswechselbare Befestigung bietet die Möglichkeit, Leitflächen verschiedener Form und Größe bei ein und demselben Dorn anzuwenden. With regard to the practical design or attachment of the wings are different Possibilities are given, either the parts are rigidly connected to one another, e.g. welded, or the wings are let into slots in the mandrel and through Screws or wedges attached so that they can also be removed if necessary. These interchangeable attachment offers the possibility of guide surfaces of various shapes and sizes Size to be used with one and the same mandrel.
