Abstract

The invention relates to mining and makes it easier to retrieve a rock sample. The gear contains a core pipe 3 with an adapter (II) 4, a spindle (Ø) 2 with a screw bit 1 inside the pipe 3, a bearing unit 5 connected to П 4 and a Ш 2 on which a stop disk is fixed inside the pipe 3 8. The connection of the node 5 Ш 2 is made in the form of a detachable lock 7 Ш 2 on the sleeve (В) 6 fixed in the node 5, which is attached to Ш 2 with ensuring the course of the longitudinal displacement of the pipe 3 relative to Ш 2. Bur 1 and В 6 filled with lugs 10 and 9. Rotating at the bottom, drill 1 destroys the soil and feeds it into the pipe 3. At the same time, B 6, due to the presence of node 5, loops Harvested into the ground without rotation. The cleaning of the sludge from the ground is carried out on the surface. To do this, latch 7 is released, a hook is inserted into the lug 10. Then B 6 and P 4 with pipe 3 are moved upwards and W 2 is held by a hook. 2 Il. ((L

FIELD OF THE INVENTION The invention relates to mining, to means for drilling with sampling of rock.

The aim of the invention is to facilitate the retrieval of a rock sample.

FIG. 1 shows a screw cone in working position, general view; in fig. 2 - the same, with its release from the ground.

The auger cone consists of

core pipe 3, fill it as the well goes down.

The sleeve 6, connected by a retainer 7 with the spindle 2, rotates together with the latter, however, due to the presence of the bearing assembly 5, the torque to the adapter 4 and the core pipe 3 is not transmitted and it sinks into the ground without rotation.

After the well has been brought to a predetermined auger drill 1, connected in the middle of the depth (or the core pipe is filled with a thread to the stem 2. The auger is ground), the rotation of the projectile stops

the drill 1 together with the pin 2 is placed and it is extracted to the surface, where it is removed from the soil inside the core pipe 3 that is fixed,

Then, from the winch, the sleeve 6, and with it the adapter 4 from the spring-loaded coring finger, for which pipe 3 is moved upward along the pinch-6 and pinch 2 in the sleeve 20, through the hook 2, held in place by the hook.

The sleeves 6 and auger bit 1 are made with parts 9 and 10, respectively.

When assembled, the projectile is lowered into the well on a string of drill pipes (not shown) connected by means of a threaded joint to the upper end of spindle 2.

Claims (1)

Invention Formula 35 The auger column, containing a core tube with an adapter, a spindle with auger bit inside the core tube, is fitted with a spindle assembly, connected with an adapter and a shpindelde, characterized in that From the rock sample facilitating the extraction of rock samples, it is equipped with a drill disk attached to The pipes and, accordingly, the spindle 2 and the screw auger 1 connected to it are rotated with the simultaneous application of some axial load on the face, which ensures the forward sliding of the projectile down. Rotating on the face, the screw auger 1 destroys the soil over the entire area of the bottom, and feeds it with the screw into the internal cavity 45 the spindle inside the core tube, while connecting the bearing assembly with the spindle is made in the form of a detachable spindle lock on a sleeve mounted in the bearing assembly, coupled with the spindle to ensure the longitudinal displacement of the core tube relative to the pindle, and the screw bit and sleeve are made with eyelets . After cleaning the projectile from the soil, the sleeve 6 together with the adapter 4 and the core pipe 3 are lowered down to the former thirty place, the sleeve b is connected to the spindle 2 by the lock 7, and the shell is ready for operation. Invention Formula five the spindle inside the core tube, while connecting the bearing assembly with the spindle is made in the form of a detachable spindle lock on a sleeve mounted in the bearing assembly, coupled with the spindle to ensure the longitudinal displacement of the core tube relative to the pindle, and the screw bit and sleeve are made with eyelets .
