Abstract (en)
[origin: EP1975323A1] The head has a drill motor including hydraulic motors (44, 46) that are provided with stators (44a, 46a) and rotors (44b, 46b), and a common shaft (50) extending along a common axis (XX'). Transmission assemblies connect ends (50b, 50c) of the shaft to grinder drums (22, 24), where the assemblies are formed of rims (52, 54), and covers (64, 66). Mechanical systems (60, 62) directly integrate the rotors of the hydraulic motors with the assemblies corresponding to the drums closer to the hydraulic motors.
