i The invention relates primarily to plowing technique, in particular, to sliding-type struts, designed to mechanize the excavation of thin layers, and is an improvement of the device icTBa ao auth. No. 977767.

The purpose of the invention is to improve the efficiency of controlling the plow in the plane of the reservoir due to the pressing pressure of the linear sections of the conveyor from the side of the executive organ to the soil of the reservoir.

; FIG. 1 shows a plow control device, a cross section; in fig. 2 - RSAres LA in FIG. one; in fig. 3 - a device for controlling the plow during the removal of the ore; in fig. 4 — Arrangement of the plow control when removing the plant from the soil.

The strict control device consists of an inclined guide 1, mounted on a square 2, which I is rigidly connected to the linear section 3 of the I conveyor. On section 3 of the conveyor, on the other hand, the bead 4 is rigidly fixed. By: the ends of the square 2; there are rigidly connected crowns

mattes 5, to which, by means of axles 1 6, are attached two traverses 7, rigidly connected with beam 8. To beam 8; hydraulic cylinders 9 are connected; engines. A control hydraulic cylinder 10 is mounted between the traverses 7 and fixed to the beam 8 by means of a hinge 11 and connected by a hinge 12 to an elbow 13. The corners of the ski 13 are fixed to the shoes 14 and 15, which interact with the tides 17 attached to a linear section 3 of the conveyor with a space of developed space; and, etc., 18 bolts mounted on the coal: e 2.

A plow control device operates as follows (in a manner.

In the initial position, the toe of the carbon 2 lies on the soil of the reservoir (Fig. 1) and is pressed to the bottom by means of the hydraulic cylinder 9 of the front axle. When this rod of the hydraulic cylinder 10 is extended so that the inclined plane 16 of the shoes 14 and

15 do not interact with tides 17 and 18.

In the process of work of the plow, in case of formation of a zamp, it is necessary to press the downhole part of the installation (the toe of the square, fig. 3). For this purpose, a hydraulic cylinder is included, 10 is folded, as a result of which 13 removes the shoes 15 from tides 18, and the shoes 14 interact with the tides 17, lifting part of the installation from the side of the worked out area, pressing the toe of the square 2 to the ground. As a result of this, the plow installation moves to a lower level of cutting lines and leaves the earthen grove, after which the device is set to its original position.

In the event that the plant leaves the ground, it is necessary to raise the toe of the square 2 (Figure 4). For this purpose, the hydraulic cylinder 10 is extended and the ski 13 is connected to the rod, moving in the soil, engages the shoe 15 with the tides 18 of the angle 2, raises the downhole part of the installation (the toe of the angle) above the soil to the required height. As a result, the plowing installation goes to a higher level of cutting lines and leaves the soil, after which the installation is reset to its original position (Fig. 1).
