Abstract

The invention relates to mining and is intended for geological exploration with coring. The goal is to increase the efficiency and reliability of work. The vibrator includes a housing 1 with a discharge channel 2, the latter has a support 3 of core tube 4 with central 5 and 6 peripheral channels and with a saddle under drop head 8 with central through 10 and with 11 side channels at an angle to the central one. The vibrator has an additional hammer head, made in the form of a connecting socket 12 with a coupling 13 of variable cross section. It has an elliptical axial channel in which a ball hammer 15 is placed with a support 16. The nozzle 12 is fixed on the striker 8, its channel is hydraulically connected to channels 10 and 11 and to the channel of the coupling. The gap between the latter and the pipe 4 is smaller than the gap between the main object and the body I, the fluid flow around the coupling 13 and flowing through the firing pin increases the impact of an additional striker on the walls of the pipe 4. The difference of the gaps between the walls of the body and the striker 8 and the walls of the pipe 4 provides strikes below the suspension point of the pipe 4. The striker 8 serves as a counterweight to the additional striker, ensuring the imbalance of the system, thus increasing its oscillatory excitability. 3 pcs. (L 4 Od CO with Phage. /

Description

The invention relates to mountain spruce, to means for geological drilling and coring,

The purpose of the invention is to increase the efficiency and reliability of operation.

Fig, 1 shows a vibrator, a longitudinal section; FIG. 2 is a section A-A in FIG. 1; Fig, 3 - drop support drummer, axonometric.

The vibrator includes a housing 1 with an injection channel 2, in which the support 3 of the core-receiver pipe 4 with the central channel 5 and peripheral channels 6 is installed. The pipe 4 is suspended in the housing 1 on the underside node 7, above the support 3 there is a striker 8, which is connected to it with the help of a spherical base 9. The striker 8 is made with an annular one, with a cross section to the hinge, with a central through channel 10 and with side channels 11 located. at an angle to the central channel 10, Koyek 8 is rigidly connected to an additional striker, including the composite pipe 12 with a clutch 13 of variable cross section, in the street 14, discharged by a ball drummer 15 and a support 16 of the drummer. An additional hammer is placed in the pipe below the bearing assembly 7 between the 4 holes 17 and 18 made in the pipe, below the additional

The pipe 4 is fitted with a seat 19 under the valve 20 discharged through channel 2, Hole 21 is made with a diameter larger than the ball valve diameter .20 and has grooves 22 for the passage of flushing fluid. In the bottom section of the nozzle 12 there is an annular protrusion 23 forming the diffuser. The support 16 is made cross-shaped to center in the hole 21 and provided with a weight 24 in the lower part,

The vibrator works as follows.

After the projectile is lowered to the bottom, the washing fluid passes through the central channel 10 of the striker 8, channel of the nozzle 12 and through channels of the sleeve 1 4 and sleeve 13 of the additional striker and seat 19 into the cavity of the core receiver 4, clearing the sludge from the discharge pipe 1 2 alternately resets the valve 20, the support 16 and the ball hammer 17, the valve 20 isolates the cavity of the core receiving pipe 4 from the dynamic pressure of the flushing fluid flow 0–

Pa 16 serves as a support for the ball hammer 15, which is re-massed in the direction transverse to the sleeve 14 under the action of the flow of washing fluid flowing through it. The strikes inflicted by the striker 15 on the walls of the sleeve 14 are enhanced by the inertia of the mass of the additional striker, the cavity of which is filled with a pulsating flow of washing liquid.

In addition, the flow around the clutch 13 fluid flow and flow through the firing pin 8 also serve to strengthen the blows of the additional striker against the walls of the core-receiving tube 4. The difference in the gaps between the walls of the housing 1 and the striker 8 and the sleeve 14 and the walls of the pipe 4 provides strikes below the suspension point (7 a) core tube 4, Punch 8 in this case serves as a counterweight to the additional striker, providing an imbalance cucT & Jfbi, which increases its vibrational excitability. For ease of release, the valve 20 and the support 1 b can be connected by a flexible element, for example a chain.
