Patent ID: 7896096

Claim:
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, wherein the drilling resources include a system for locking and unlocking the drilling rods, the system for locking and unlocking including a drill-bit guide along which can slide a guillotine, the guide being arranged to be driven by two slides in turn arranged to be driven by a guillotine jack.
