         5 . A hydraulic drilling machine according to  claim 1 , wherein the width of the chassis is approximately equal to one third of the length of the chassis and is slightly longer than a drilling rod. 
     
     
         6 . A hydraulic drilling machine according to  claim 1 , wherein the resources for attaching the resources to the arm of the mini-digger include a turret having dimensions adapted for connection to the arm of the mini-digger, the turret being arranged to connect the chassis of the drilling machine to the arm of the mini-digger for enabling the drilling machine to rotate around the axis of the arm of the mini-digger. 
     
     
         7 . A hydraulic drilling machine according to  claim 1 , wherein the cross-members located in the bottom part of the chassis comprise a frame for accommodating a bottom chassis including two cross-members located approximately parallel to each other, one of the extremities of the two cross members being connected together by the drill-bit guide at one of the extremities and by a metal plate having a bore for reducing the weight of the plate, at the other extremities of the two cross members. 
     
     
         8 . A hydraulic drilling machine according to  claim 1 , wherein the rotary motor is fixed to a support including a metal plate having a lug along each of its lengths, the lug including two ball bearings located on opposite sides of an axis of symmetry of the lugs. 
     
     
         9 . A hydraulic drilling machine according to  claim 7 , wherein each lug has a rectangular part fixedly mounted in an extension of one of the widths of the lug, the rectangular part being arranged to prevent the rotary motor support from derailing as the rotary motor slides along the cross-members of the internal chassis. 
     
     
         10 . A hydraulic drilling machine according to  claim 1 , wherein, in the working position, the chassis of the drilling machines is stabilized by two jacks located along cross-members of the chassis and fixed to the cross-members by a metal plate and rings. 
     
     
         11 . A hydraulic drilling machine according to  claim 1 , wherein the hydraulic system includes three points for injection of oil obtained from the hydraulic system of the mini-digger, one of the entry points being arranged to increase the working power of the components of the drilling machine. 
     
     
         12 . A hydraulic drilling machine according to  claim 11 , wherein the hydraulic system includes a quarter-turn valve for feeding either the rotary motor or the other elements for participating in the operation of the drilling machine. 
     
     
         13 . A hydraulic drilling machine according to  claim 1 , further including an electrical system connected to a control panel of the mini-digger, the electrical system including an emergency stop switch and a power feed for a working lamp connected to a cigar lighter of the chassis. 
     
     
         14 . A hydraulic drilling machine according to  claim 13 , further including a power feed for vehicle-mounted electronics, the power feed being mounted as a take-off from a power feed of a working lamp. 
     
     
         15 . A hydraulic drilling machine comprising:
 a metal chassis shaped as a rectangular parallelepiped having:
 a first lengthwise end and a second lengthwise end opposite the first lengthwise end, the first lengthwise end arranged to be connected to a hydraulic source, 
   drilling resources located in a bottom part of the metal chassis at the second lengthwise end, the drilling resources including:
 a rotary motor arranged to drive drilling rods during a drilling operation, the rotary motor arranged to extend the drilling rods in a direction perpendicular to the longest face of the metal chassis, between the first and second lengthwise ends, 
   support devices arranged to stabilize the position of the drilling machine during a drilling operation, the support devices mounted on the metal chassis and arranged to create a resultant force coaxial to the axis of the drilling resources 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 end, the further resources being capable of operation without the addition of an extra hydraulic unit.
