- the displacement of the two secondary hydraulic pumps 118,120 is zero. There is no flow in the closed circuits, the latter being force-fed, and the hydraulic motors do not turn. To rotate one of the motors, it is necessary to change the displacement of the associated secondary hydraulic pump.
- FIG. 10 illustrates a second embodiment of the first and second hydraulic circuits 1100, 1300.
- the first hydraulic circuit 1100 comprises:
- first main hydraulic pump 1120 a first main hydraulic pump 1120; and - a first distribution member 1140 which comprises a first hydraulic junction 1150 which is connected to the first main hydraulic pump 1120 and the first hydraulic motor 32, and a second hydraulic junction 1170 which is connected to the first main hydraulic pump 1120 and to the second hydraulic motor 52.
- the drilling device comprises the first dispensing member.
- the first hydraulic circuit further comprises a first proportional distributor 1180 which is arranged between the first distribution member 1140 and the first hydraulic motor 32, and a second proportional distributor 1190 disposed between the second hydraulic motor 52 and the first distribution member 1140.
- the flow distribution between the first and second hydraulic motors is carried out by the two proportional distributors 1180, 1190.
- Each of the proportional valves has the function of adjusting the speed and direction of rotation of the hydraulic motors. It can take all the flow of the main hydraulic pump 1120.
- the second hydraulic circuit 1300 which supplies the third and fourth motors 62,72 is identical to the first circuit 1100.
- the second hydraulic circuit comprises:
- a second distribution member 1340 connected to the second main hydraulic pump 1320, the second distribution member 1340 supplying a second group of two motors consisting of the third and fourth motors 62,72. This second group being different from the first group and the drilling device 20 comprising the second distribution member 1340.
- FIG. 11 illustrates a drilling machine according to the invention which is a drilling and mixing machine 300.
- drilling and mixing machine 300 comprises a frame 312 consisting of a longitudinal bar 313, generally called Kelly.
- the machine 300 further comprises a mast 315 and a carriage 317 movable along the mast, the carriage being fixed to the longitudinal bar to allow movement of the longitudinal bar.
- the machine 300 further comprises a drilling device 320, carried by the lower end 312a of the longitudinal bar.
- the drilling device 320 is similar to the drilling device 20 described above except that the cutting teeth are cutting and mixing blades for cutting and mixing the soil. Such blades are known elsewhere and will not be described in detail here.
