Description

one

The invention relates to the field of mining and can be applied tfi sampling of seabed soil.

Known samplers for the study of bottom sediments, carried out in the form of group tubes III.

The lack of data samplers is the difficulty of core recovery from core-cavity CAVITY, reducing labor productivity.

. The closest to the proposed T.: Schiche essence and the achieved result is a sampler containing a split core receiver in two parts, quick disconnect wedge gates connecting the core receivers, and a mechanism for holding the gates in the closed position 2.

However, the rate of the technical solution is convenient only with a relatively small length of the sampler (up to three meters). For large sizes due to body weight of the components of the connection and separation of them. inconvenient and time consuming.

The purpose of the invention is to increase labor productivity by facilitating extraction operations. core and preparation for work.

This goal is achieved. By the fact that in the known sampler, parts of the core receiver are pivotally connected with the potential of the longitudinal relative displacement.

FIG. I schematically depicted an sampler, section A-A in FIG. 2; in fig. 2 is a view B in FIG. one; in fig. 3 view B in FIG. one.

Sampler CO.STOIT from a core receiver in the form of two parts, folded with shelves of channels 1 and 2, the walls and shelves of the lower ends of which are pointed and strengthened. From the inside to the walls of both channels riveted elastic valves 3 of spring steel sheet. On the opposite side of the channel 1, there is a flange 4 for fastening the anvil of the vibro-hammer, and on the channel bar 2 there is an end platform 5 which, when the pipe is loaded, abuts the ground in the flange 4 and perceives through it the external impact of vibro-hammer. Channels 1 and 2 are connected to each other by hinged joints consisting of bush 6 and pins 7. Bushes 6 are welded in channel 1, and barrel 7 is connected to channel 2 with axial clearance allowing for channel movement relative to each other. Along the other line of the connector of the channels, quick-detachable wedge gates 8 are arranged in the form of cylindrical rods cut in half at an angle to the axis. One of the halves of the rod is welded to the channel 1, the other to the channel 2 so that when the platform 5 stops at the flange 4, they are in full engagement, and when the channels move apart, they unhook the load on the hinges and locks from the internal pressure of the soil, they are located more often in the lower part and less often in the upper part, and the reduction in frontal resistance from the frontal parts of the hinges and constipations, they are made with an axle.

 To pre-fix the gates in a closed position before starting to drill on one of the channels, there is a mechanism in the form of a push latch 9. To separate the Schleellers, and then open the pipes on the channel 2, the threaded sleeve 1O is welded with a screw 11, abutting when screwed into the flange 4 Its rotation is performed by the lever 12 ,. through the hole in the screw. Opening the core receiver with the same lever when changing its position in the screw hole.

The sampler works as follows.

Before putting on the ground, the undercarriage is screwed out to a position sufficient to ensure that it does not interfere with the closing of the end platform 5 with the flange 4. The core receiver is closed 51. and automatically locks in the closed position with a prulusyno latch 9. At the beginning of drilling, due to the ground reaction, both channels align with the ends and the wedge gates come in one after the other. The forces appearing on the surface of the engagement are determined by the reaction of the soil at the bottomhole and

On the side surfaces of the channel bar 2, a. also by the internal spreading force of 6 tons of soil filling the pipe. After removing the sampler from the well and laying it in a horizontal position with the channel 2, turning the lead screw 11 upward produces a separation of the channels and then opening the core receiver with the lever 12.

. Instead of channels, it is possible to use an angular profile or halves cut along a round pipe. The ball {shry and bolts can be located outside, as in the example, or inside the pipe. The advantages of the proposed design lie in the fact that the rigidity of the split core receiver is ensured by connecting the halves with hinges and locks along its entire length, and not just in the end parts. When working, the operations of combining the halves with each other are eliminated, instead of dragging. In the direction of the detachable half, it is rotated on hinges with the help of a lever without the use of considerable physical effort by practically one person. As a result, due to the acceleration of auxiliary operations, an increase in labor productivity is achieved when testing marine sediments.

Fore

Mule Invention. neither

Sampler, containing split core receiver in two parts, quick wedge gates connecting core receiver parts with each other as well as a mechanism for keeping the gates in a closed position, so that increase in labor productivity due to the flyover of core extraction and preparation for work, parts of the core receiver are connected by a hinge but with the possibility of longitudinal relative mixing.
