Abstract
A continuous-screw drilling equipment for drilling the ground having an extension rod with at least two sections of rod of the type in which the continuous screw constituting the tool is carried by an extension rod which is able to slide along a motor assembly from which it receives the rotary motion about a longitudinal axis thereof; the extension rod is made up of at least two coaxial sections or stretches of rod, of which the internal one (4) is without turns and is rigidly connected at the bottom end to the continuous-screw tool (5), whilst the external one (6), which is able to slide on the internal one (4) and along the motor assembly (3), has some turns constituting the screw (7) in the bottom area, the rods (4 and 6) being equipped with splined couplings for connection with one another, and the external rod (6) is in turn equipped with a splined coupling also with respect to the motor (3) so as to transmit the rotary motion from the motor to the respective screw (5 and 7).
