摘要： In the auger cleaning device (8) according to the invention, in the closed configuration the tool-holder support forms a pass-through opening (82) arranged for allowing the passage of a helical drilling tool (6), the cleaning tool (170) engaging with the screw of the drilling tool (6) and, actuated by the actuation system (12, 12′,12″, 4), is arranged for rotating around the drilling tool (6) following at least one of its threads (60) so as to remove the debris lying on the drilling tool (6). In the open configuration the cleaning tool (170) is disengaged from the drilling tool (6) and preferably farther from it, with respect to when it is in the closed configuration.

摘要： A system and method detect at least one mechanical locking position of a drill string in a soil drilling machine. According the system and method, there are: a sensor apparatus which is configured to detect first data indicating the position assumed by the top of the drill string and second data indicating the position assumed by the bottom of the drill string. A control unit calculates the estimated length of the drill string based on the data and to compare the estimated length with a reference length value. A pair of kelly rods is in a mechanical locking position; and a signaling apparatus is configured to signal when the estimated length corresponds to a reference length value.
