Description

In the proposed soil tonnage, a plate is already known in other soil tonners for cutting the soil, but, unlike known constructions of this kind, this plate is made movable in the grooves of the wall of the submernose body with the help of cables attached to its ends.

Such a device makes it possible to take samples of non-bonded soil (loose) and to determine the weight of the skeleton of the latter from these samples.

In FIG. 1 shows a vertical section of such a submersible; FIG. 2 is a section along AA in FIG. one; and FIG. 3 is a section along the explosive in FIG. 2

The grunthos is a square metal cup 1, mounted on a fork 2, lowered to the depth of the specimen using rods.

When the submersible is lowered to the required depth, the sharp lower edge 3 freely smashes it into the soil, which fills the inside of the cup 1. After this, a certain volume of the soil is cut. h using a special knife-curtain 4, 5, which can move in the grooves 6 of the vertical side walls of the glass 1 and pass through the lateral side

slots 7 and 8 in the upper and lower parts of the two other side walls of the glass 1. The curtain is a flexible metal plate with a cut-out middle section across the width (a) of the internal cavity of the glass 1.

To the ends 4a and 5a of the continuous parts 4 and 5 of the curtains are attached on both sides of each of them cables.

Cables coming from the lower end 5a of part 5 of the curtain run along horizontal channels 10a (Fig. 3) and run vertically but channels 10 (Fig. I and 2) on the sides of part 4 of the plate, pointing upward and outward. to the lower edge 4a of part 4 of the plate, go in the opposite direction but 1 channels 10c and exit along the vertical channels 11 to the outside through the cavity 9 in the fork 2.

When the shutter cable is pulled through the channel 10 upwards, the solid part 5 of the plate passes through the lower slot 8 and the edge 5a cuts off the volume of soil placed in glass 1, limiting it to the bottom. At the same time, the continuous part 4 of the curtain with the edge 4b produces cutting off the soil volume captured by the cup 1, limiting it from above.

After the subsoil is removed to the day surface, the reverse is performed using a reverse cable.

moving the curtains 4, 5, and the sample taken is released and emptied out of the stack.

The subject of invention.

Grunthos with the use of a flexible plate for imaging and sampling of unrelated soil to determine the weight of its skeleton in a unit of volume, characterized in that the plate is made by shifting the IB grooves of the gooseneck body steak with the help of attached to its ends the cables pulled out.
