Abstract:
A hydraulic drilling machine has a metal chassis shaped as a rectangular parallelepiped, drilling resources located at the front of the chassis, a rotary motor to drive drilling rods, and a hydraulic circuit. An electrical circuit powers the various components of the drilling machine. The machine can be mounted on the arm of a hydraulic mini-digger and operate without an extra hydraulic unit.
