SU378749A1 - DEVICE FOR SELECTION OF THE MONOLIT OF A CUBIC-SHAPED SOIL - Google Patents

Description

one

The invention relates to engineering and geological surveys, in particular, to devices for the selection of a soil monolith.

Devices are known for taking a cube-shaped monolith of soil from holes, comprising a tubular body with a vertical slot and a soil collecting container located in its cavity.

The purpose of the invention is to increase the degree of mechanization of the selection process of the monolith.

This is achieved by the fact that the grain intake is made in the form of coaxially hingedly mounted on a tubular body with the possibility of horizontal movement in the vertical slot of the body of the power cylinder with a stem, at the end of which the cutting knife with upper and lower cutting edges and U-shaped knife with cutting edges are rigidly fixed. . The knife is mounted so that it can move along an arc in a vertical slot of the tubular body by means of an additional power cylinder hinged in the lower part of the body. Moreover, the cutting edges of the U-shaped knife are installed perpendicularly to the cutting edges of the scoring knife.

FIG. 1 shows the described device, a longitudinal section; in fig. 2 - the same, top view; in FIG. 3 - U-shaped knife in a perspective view; in fig. 4 - a cutting knife in a perspective view.

The proposed device consists of a tubular body 1 with a vertical slot a.

In the upper part of the housing, the power cylinder 3 is pivotally connected on the axis 2, with the rod 4, at the end of which the cutting knife 5 with the upper A and lower B cutting edges and the U-shaped knife 6 are rigidly fixed

with cutting edges B. The knife 6 is mounted for movement along an arc in a vertical slot of the tubular body / by means of a bracket 7, which is hingedly connected to the rod 8 of the power cylinder 9. The last

pivotally fixed by means of the axis 10 in the lower part of the body /.

The described device works as follows. To select a monolith of a soil of cubic shape, a hole with a diameter slightly larger than the diameter of the tubular body is opened, into which the proposed device is lowered to a predetermined depth using a cable 11. In this case, the upper and lower power cylinders,

The knives connected to the cutting 5 and U-shaped 6 knives are in the initial state: (shown in Fig. 1 by the dotted line).

Then, through the high pressure line 12, compressed air is supplied to the power cylinder 9,

which moves the rod 8. In this case, the U-shaped knife will pass through a vertical slot and in the tubular housing / and will cut into the soil of the wall of the hole.

After the horizontal position is reached, the movement of the knife 6 will stop and high pressure line 13 will supply compressed air to the power cylinder 3, the rod 4 of which will move forward and with the help of cutting knife 5 with the upper A and lower B cutting edges will separate the monolith from the soil mass.

Then, however, the high-pressure lines 14 supply compressed air to the power cylinder 9, the rod 8 of which will move backwards and return the knife 6 to its original position. The tubular body 1 with a scrap 11 is pulled out to the surface, and the high-pressure pipe 15 is supplied with compressed air into the power cylinder 3, the stem 4 of which moves: backwards, resulting in a cutting knife 5 from the upper A and lower. B the cutting edges will return to their original position, ensuring the reception of the cube-shaped soil from the U-shaped knife of the monolith.

4 Subject of the invention

A device for sampling a monolith of a cube-shaped soil from holes, including a tubular body with a vertical slot and a soil collector located in its cavity, characterized in that, in order to increase the degree of mechanization of the selection process of the monolith, the soil sampler is made in the form

coaxially pivotally mounted on a tubular body with the possibility of horizontal movement in a vertical slot of the body of the power cylinder with a rod, at the end of which a cutting knife with

the upper and lower cutting edges, and the Pooky knife with cutting edges, mounted to move along an arc in the vertical slot of the tubular body by means of a hinged pin

the lower part of the body of the additional ram cylinder, the cutting edges of the Igozh are installed perpendicular to the cutting edges of the scoring knife.
