<p>The machine comprises an excavator device with a rotary cutter of transverse axis of rotation. It is carried, on the side, by a running vehicle not straddling the ditch and is associated with a conveyor belt. The cutter (2 or 41) rotates in the opposite direction to the wheels of the vehicle carrying the machine. The conveyor belt (15) is directed towards a zone located in front of the vehicle, and the relative positions of the cutter (2 or 41) and of the conveyor belt (15) are such that most of the debris detached by the cutter (2 or 41) is thrown onto the conveyor belt (15). Behind the cutter (2) is a driving roller (4) rotating in the direction of the wheels of the vehicle carrying the machine. The profile of the driving roller (4) is wider than that of the cutter (2). The machine is suspended at the end of a transverse jib (16 or 91) carried by the vehicle. The connection between the machine and the jib is a joint of longitudinal axis. A jack (32) mounted between the machine and the jib determines the roll angle of the machine. The latter carries an instrument for measuring its verticality (76, 77, 78) which controls a valve (82) feeding the jack (32), so as to ensure the verticality of the machine. The cab (98) of the vehicle is transversely displaceable as a function of the position of the jib (91) carrying the machine.</p> |
