WORKING MACHINE AND METHOD OF SOIL TREATMENT Russian patent published in 2020 - IPC E21B7/02 E21B17/07 

FIELD: machine building.

SUBSTANCE: invention relates to working construction machine for soil treatment. Proposed machine comprises mast, control device, power rotary head, telescopic driving drill string, rope suspension and winch. Drill string comprises at least two drive drill rods. Gripping rods are provided with gripping plates and locking recesses with recording devices. Control device is configured to automatically lock the drill rod. Providing possibility of first torque application to driving drill rod, wherein the blocking element is applied to the gripper bar of the opposite driving rod with low pressure. Provided is the possibility of movement in axial direction of both driving drill rods relative to each other, until locking element turns in circumferential direction into locking recess. To implement the method of soil treatment by means of the control device the driving drill rods are automatically locked or unlocked. By means of the first recording device, angle of rotation of at least one driving rod and/or by means of the second recording device is recorded change of force, of torque or pressure in hydraulic system. Control device is used to determine the locking and/or unlocking of the driving drill rods depending on the detected turning angle and/or the detected change of force, torque or pressure.

EFFECT: technical result is higher efficiency and reliability of soil treatment.
