Abstract

The invention relates to mining. The goal is to increase the preservation of the core structure. The coring pick-up contains a mowing ground 5, body 1 with a guide part 2. Grunthos 5 has a submersible drive of rotation in the form of a gearmotor 10 and a cylinder 8 of its feed. A movable support yoke 9 and a sleeve 6 are fixed to the rod 7 of the cylinder 8 and connected to the ground bearing carrier 5 by the bearing unit 12. The gear motor 10 is fixed on the cross bearing 9. The guide part 2 is made with a longitudinal slit 3 for engagement with the cross beam 9 when the submersible bearing 5 is fed. When drilling the latter simultaneously crush the sleeve 6 into the ground. In the working position, the crosshead 9 switches the cylinder 8 to reverse and turns off the rotation of the gearmotor 10. In this case, the rod 7 retracts the scooping submersible into the body 1 in the reverse direction. 2 Il.

scrap 12. Gearmotor 10 is fixed on the traverse 9. The guide part 2 is made with a longitudinal slit 3 for interacting with the traverse 9 when feeding the submersible 5, when the latter is drilled, it is simultaneously crushed

sleeve 6 in the ground. In the working position, the crosshead 9 switches the cylinder 8 to reverse stroke and turns off the rotation of the gearmotor 10. When this happens, the rod 7 retracts the charging groundwater carrier into the housing 1, 2 Il.

The invention relates to the field of mining, and more specifically to devices using 1F1M for sampling core samples from the borehole walls.

The purpose of the invention is to improve the preservation of the core structure.

FIG. 1 shows a corona sampling 11K general view, in the position of descent; in fig. 2 - the same, top view.

The side core sampler comprises a housing 1 with a guide part 2, having a longitudinal slot 3 and guides 4. Inside the part 2 there is a scuba submersible 5 with a core receiver 6 fixed to the rod 7 of the submersible cylinder of the feed cylinder 8. A movable traverse 9 is also fixed on the rod 7, on which, in turn, the gearmotor 10 is fixed, which serves to drive the rotation of the submersible. The kinematic linkage of the motor-reducer 10 with the submersible 5 is provided by gear 11, while the reactive moment is perceived by the longitudinal slit 3 when interacting with the traverse in the process of feeding the primer, and the freedom of rotation of the submersible is provided by connecting it with the traverse 9 and the sleeve 6 with the bearing unit 12. The motor the gearbox and feed cylinder are driven by squeezing air or liquid from the surface. In the extreme position of the traverse 9 includes a sound (electric or pneumatic) signal 13.

The coring device works as follows.

To collect a soil sample, a core collector is lowered into a large borehole (hole) on the drill pipe or cable and suspended from a gap of a predetermined interval. The support of the core sampler is not needed for the bottom. A working agent is supplied to the feed cylinder 8, the liner 7 is advanced and that

From our part 2, we push the milling grouser 5 and the core tube 6 up to the stop in the borehole wall. Next, the working agent is supplied to the gearmotor 10, and thus the rotating grounding head 5 is brought into rotation. The grounding head 5 is drilled and the sleeve 6 is simultaneously pressed into the ground. When approaching the extreme working position of the yoke 9 turns on the acoustic signal 13, after which the installation operator switches the feed cylinder 8 to reverse and turns off the rotation of the gearmotor 10, the choke 7 retracts the grounding head into the housing 1 in the reverse stroke the retracted rod 7 corresponds to the transport position of the submersible 5 milling the j in the housing 1. Next, the lifting mechanism of the drilling rig is turned on and the device is raised to the surface. On the surface, the feed cylinder 8 is turned on to the straight xorf, thereby pushing the scooping submersible 5 and the sleeve from the housing to a position that is convenient for removing the tsern.
