<p>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).</p> |
