The present invention relates to a machine for digging into the lower layers of the ground, wherein said machine comprises the following members: a base frame (1), a ground excavator (2) and a driving chain-type working organ (3) that is suspended from the frame (1) by a device (4) so as to be capable of forced rotation about two geometrical axes (17, 18). During operation of the machine, the axis (17) is perpendicular to the support surface (5) of the drive section (6) of the frame (1), while the axis (18) is parallel to the longitudinal axis (a-a) of said drive section (6). During operation, the rotation of the working organ (3) about the two axes (17, 18) makes it possible to dig excavations with a bottom that is horizontal or has a predetermined lateral inclination while maintaining an important width, to form sloped excavations or to dig excavations having various profiles.

Cette invention concerne une machine servant à creuser dans les couches inférieures du sol, laquelle comprend les éléments suivants: un châssis de base (1), une excavatrice de terre (2), ainsi qu'un organe de travail et d'entraînement à chaîne (3) qui, à l'aide d'un dispositif (4), est suspendu au châssis (1) de manière à pouvoir tourner en force autour de deux axes géométriques (17, 18). Lorsque la machine est en position de travail, l'axe (17) est perpendiculaire à la surface de support (5) de la partie motrice (6) du châssis (1), tandis que l'axe (18) est parallèle à l'axe longitudinal (a-a) de ladite partie motrice (6). Lors du fonctionnement, la rotation de l'organe de travail (3) autour des deux axes (17, 18) permet de creuser des excavations ayant un fond horizontal ou d'une inclinaison latérale donnée tout en conservant une grande largeur, de former des excavations en pente, et de creuser des excavations ayant des profils divers.
