Title (EN) DEVICE FOR MAKING HOLES IN THE GROUND
(FR) DISPOSITIF DE PERÇAGE DE TROUS DANS LE SOL
Abstract:
(EN) The proposed device for making holes in the ground comprises, according to the invention, at least one additional driven eccentric shaft (4), mounted coaxially to the main eccentric shaft (1) and carrying on its shifted necks truncated conical rollers (5) and at least one cylindrical reversible roller (6). The smaller base of the truncated conical roller (5) located in proximity to the cylindrical reversible roller (3) of the main eccentric shaft (1) is commensurate with its diameter. The main and the additional eccentric shafts (1, 4) are mounted on a frame (7) connected through a kinematic link to the working machine and consisting of at least two longitudinal ribs (8) located symmetrically in relation to the longitudinal axis of said shafts (1, 4) and rigidly interconnected by crossbars (9).
(FR) Le dispositif décrit comprend, selon l'invention, au moins un arbre excentrique mené supplémentaire (4) monté de manière coaxiale par rapport à l'arbre excentrique principal (1), et portant sur ses épaulements décalés des rouleaux coniques tronqués (5) et au moins un rouleau cylindrique reversible (6). La plus petite base du rouleau conique tronqué (5), qui est située près du rouleau cylindrique réversible (3) de l'arbre excentrique principal (1), a des dimensions qui sont fonction de son diamètre. Les arbres excentriques principale et supplémentaire (1, 4) sont montés sur un cadre (7) relié par une liaison cinétique à la machine d'entraînement et composé d'au moins deux nervures longitudinales (8) placées symétriquement par rapport à l'axe longitudinal desdits arbres (4) et mutuellement reliées de manière rigide par des traverses (9).
