Abstract

1. A machine for digging in the ground vertical-walled trenches of great depth, having at least one cutter consisting of two half-drums (2a, 2b) bearing tools (4, 4a, 4b) at their peripheries and supported by a vertical core (3) arranged between them, the machine being characterized by the fact that the axes (7) of the two half-drums (2a, 2b) are slightly inclined downwards and outwards from the plane of the core (3).

Claims (8)

Patentansprüche:Patent claims: ■1 &ngr;. Maschine zum Ziehen von Erdgräben mit senkrechten Wänden mittels Fräsen, bei welcher zwei Werkzeuge tragende Halbtrommeln durch einen senkrecht angeordneten Steg abgestützt sind, dadurch gekennzeichnet, daß die Achsen (7) der beiden Halbtrommeln (2a, 2b) leicht nach unten geneigt verlaufen, indem sie von der Ebene des Steges abweichen.■1 vngr;. Machine for digging trenches with vertical walls by means of milling, in which two half-drums carrying tools are supported by a vertically arranged web, characterized in that the axes (7) of the two half-drums (2a, 2b) run slightly inclined downwards, deviating from the plane of the web. 2. Maschine nach Anspruch 1, dadurch gekennzeichnet, daß die Achsen (7) der Halbtrommeln um etwa 1-10° geneigt sind.2. Machine according to claim 1, characterized in that the axes (7) of the half drums are inclined by approximately 1-10°. 3. Maschine nach einem der Ansprüche 1 oder 2, dadurch gekennzeichnet, daß die auf den Halbtrommeln (2a, 2b) angeordneten" Werkzeuge (4a) in der Nähe des Steges (3) unmittelbar nebeneinander arbeiten, sobald sie sich im unteren Teil der Maschine befinden.3. Machine according to one of claims 1 or 2, characterized in that the tools (4a) arranged on the half drums (2a, 2b) work directly next to one another in the vicinity of the web (3) as soon as they are in the lower part of the machine. 4. Maschine nach irgendeinem der vorangegangenen Ansprüche, dadurch gekennzeichnet, daß die an der Außenfläche der Halbtrommeln (2a, 2b) angeordneten Werkzeuge (4b) derart nach außen versetzt sind, daß sie, sobald sie sich im unteren Teil der Halbtrommeln befinden, den Erdboden über eine Breite abtragen, welche im wesentlichen der Breite entspricht, die von den beiden Halbtrommeln in ihrem oberen Teil eingenommen wird.4. Machine according to any one of the preceding claims, characterized in that the tools (4b) arranged on the outer surface of the half-drums (2a, 2b) are offset outwards in such a way that, once they are in the lower part of the half-drums, they remove the soil over a width which corresponds substantially to the width occupied by the two half-drums in their upper part. 5. Maschine nach irgendeinem der vorangegangenen Ansprüche, dadurch gekennzeichnet, daß die Enden der auf jeder Halbtrommel (2a, 2b) angeordneten Fräswerkzeuge (4, 4a, 4b) auf einem Kegelstumpf liegen, dessen Erzeugende die gleiche Neigung wie die Achsen (7) der Halbtrommeln haben, sodaß die Spitzen dieser Werkzeuge auf einer im wesentlichen horizontalen Linie liegen, sobald sie sich im unteren Teil der Halbtrommeln befinden.5. Machine according to any one of the preceding claims, characterized in that the ends of the milling tools (4, 4a, 4b) arranged on each half-drum (2a, 2b) lie on a truncated cone whose generatrix has the same inclination as the axes (7) of the half-drums, so that the tips of these tools lie on a substantially horizontal line as soon as they are in the lower part of the half-drums. 6. Maschine nach irgendeinem der vorangegenangen Ansprüche, dadurch gekennzeichnet, daß der Steg (3) einen trapezförmigen Vertikalquerschnitt besitzt.6. Machine according to any one of the preceding claims, characterized in that the web (3) has a trapezoidal vertical cross-section. 7. Maschine nach irgendeinem der vorangegangenen Ansprüche, dadurch gekennzeichnet, daß die beiden Halbtrommeln durch einen fest mit dem Steg verbundenen Motor angetrieben werden, welcher mit einer gerieften wagerechten Hohlwelle bestückt ist, in welche eine Keilwelle eingreift, die jede der beiden Halbtrommeln in Drehung versetzt, wobei die Winkelabweichung der Motorachse von der der beiden Halbtrommeln durch das in den Riefungen vorhandene Spiel ausgeglichen wird.7. Machine according to any one of the preceding claims, characterized in that the two half-drums are driven by a motor firmly connected to the web, which is equipped with a grooved horizontal hollow shaft into which a splined shaft engages, which sets each of the two half-drums in rotation, the angular deviation of the motor axis from that of the two half-drums being compensated by the play present in the grooves. 8. Maschine nach irgendeinem der vorangegangenen Ansprüche, dadurch gekennzeichnet, daß der Steg (3) zwei Halbtrommelpaare trägt, deren Drehachsen im wesentlichen in gleicher Höhe liegen und welche in entgegengesetztem Drehsinn angetrieben werden.8. Machine according to any one of the preceding claims, characterized in that the web (3) carries two half-drum pairs, whose axes of rotation are essentially at the same height and which are driven in opposite directions of rotation.
