FIELD: drilling equipment. SUBSTANCE: invention is related to face means of drilling equipment meant to drill holes. Proposed turbo-drill has body, system of rotors put on shaft and spacing sleeves placed between rotors. In accordance with invention rotors are manufactured in the form of ratchet-wheels with paired ledges arranged on periphery and facing in diametrical opposition. Rotors are put on shaft with developed ledges and contact during slide fitting spacing sleeves attached to body. Spacing sleeves and body have mating side grooves where partitions interacting with rotors are placed for movement. Partitions are different in height that amounts to value of entry of partitions into side grooves of spacing sleeve. EFFECT: increased efficiency of usage of energy of flow of working fluid by creation of moment of hydraulic impact loads on rotor, possibility of periodic increase of impact loads, if necessary, under constant flow rate of liquid and improved operational reliability of turbo-drill thanks to mechanical transfer of torque from body to rotor. 1 cl, 2 dwg |
