Auger cleaning device for removing debris from a helical drilling tool, drilling machine provided with said cleaning device and use of said drilling machine

1) Auger cleaning device for removing debris from a helical drilling tool provided with one or more threads and arranged for drilling ground, the cleaning device comprising:

• a tool-holder support;
• at least one cleaning tool constrained to the tool-holder support;
• and wherein
• the cleaning tool is arranged for being actuated by an actuation system and the tool-holder support is arranged for reversibly passing from an open configuration to a closed configuration so that:
• in the closed configuration the tool-holder support forms a pass-through opening arranged for allowing the passage of a helical drilling tool, the cleaning tool engaging with the screw of the drilling tool and, actuated by the actuation system, it is arranged for rotating around the drilling tool running along at least one of its threads so as to remove the debris lying on the drilling tool;
• in the open configuration the cleaning tool is disengaged from the drilling tool and preferably farther from it, with respect to how far it is in the closed configuration.
