Abstract:
1. A hydraulic drilling machine comprising a metal chassis shaped as a rectangular parallelepiped having a first lengthwise extremity arranged to be connected to a hydraulic source, drilling resources located in a bottom part of the metal chassis at a second lengthwise extremity opposite to the first lengthwise extremity, the drilling resources including a rotary motor for driving drilling rods during a drilling operation, the drilling rods, when mounted on the rotary motor during a drilling operation, extending in a direction perpendicular to the longest faces of the metal chassis between the first and second lengthwise extremities, stabilization resources for the position of the drilling machine during a drilling operation mounted on the metal chassis to create a resultant force coaxial to the axis of drilling resources including the rotary motor and the drilling rods when connected to the rotary motor during a drilling operation, and further resources arranged to be mounted on an arm of a hydraulic mini-digger arranged to be connected at the first lengthwise extremity, the further resources being capable of operation without the addition of an extra hydraulic unit, at least two rings being attached, to an upright of the chassis so each ring is attached above another ring, the rings being arranged to receive fixing lugs of a basket for storing the drilling rods.
