The invention discloses an underground telescopic telescopic short drill collar while drilling, and relates to the technical field of drill collars. The invention includes a plurality of drill collar modules, the plurality of drill collar modules are arranged in order from top to bottom, the upper end of the drill collar module located at the uppermost end is equipped with a connector, and the lower end of the drill collar module located at the lowermost end The drill collar module is composed of a telescopic mechanism and a sampling mechanism. The telescopic mechanism is located at the upper end of the sampling mechanism, and the upper end of the telescopic mechanism is fixed with a second connecting piece. In the present invention, the first transmission motor is activated to drive the protective casing to move on the outside of the limiting shaft, and the length of the drill collar module can be adjusted, so that the length of the device can be adjusted according to the needs of the user, thereby greatly increasing the scope of application of the lifting device. The first transmission motor is activated to fine-tune the position of the sampling mechanism, and the second transmission motor is activated to rotate the sampling cylinder, so that the soil in multiple positions can be sampled relatively simply, which brings great convenience to the user.
Description
technical field [0001] The invention belongs to the technical field of drill collars, in particular to an underground telescopic telescopic short drill collar while drilling. Background technique [0002] The drill collar is located at the bottom of the drill string and is the main component of the lower drilling tool assembly. In order to facilitate the tripping and drilling work, elevator grooves and slip grooves can be processed on the outer surface of the inner thread of the drill collar. The drill collar is made of rolled or forged AISI4145H chromium-molybdenum alloy steel. The content of trace elements is effectively controlled; [0003] Drill collars are generally divided into 3 types, auger collars, non-magnetic drill collars and integral drill collars. The integral drill collar is a smooth thick-walled round tube with connecting threads at both ends, and the auger collar is processed on the outer cylindrical surface of the circular drill collar. 3 right-handed hel...
