Description

eleven

The invention relates predominantly to the plow technique, in particular, to sliding plow installations, intended to mechanize the excavation of thin layers.

The purpose of the invention is to increase the reliability of the device for controlling the plow and simplify the design.

Figure 1 shows a plow control device, a cross section; figure 2 - section aa in figure 1; Fig. 3 is a schematic diagram of the position of the middle part of the plow installation at the height of the plow from the soil; 4 is the same when the Zemnik is removed.

The plow control device consists of an inclined guide 1 fixed on an angle 2, which is rigidly connected to the linear section of the conveyor 3. A flange 4 and a subconveyor beam 5 are fixed to the section of the conveyor 3 on the side of the exhausted device. The angle 2, inclined guide 1, of the conveyor section 3, bead 4 and sub-conveyor beam 5 are rigidly interconnected. In the middle of the square 2 there is a tide 6. The sub-conveyor beam 5 is made with a through horizontal opening 7 in which the slider 8 is located, through a horizontal hinge 9 connected to the shoe 10. With the cTopOHbs of the exhausted space, the slider 8 has an eyelet 11 for attaching the shifter 12 to it. The shoe 10 in the front has a groove 13 with an inclined plane 14 and a supporting surface 15. The groove includes tide 6 of a square 2, which orients the movement of the shoe in the vertical and horizontal

planes relative to a square 2. I

The position of the slide 8 relative to

the conveyor beam 5 is fixed by means of the finger 16 and the holes 17 and 18, made respectively in the slider 8 and the conveyor beam 5. The distance between the holes in the slider for fitting relative to the beam is directly proportional to the amount of lifting of the angle piece.

The plow control device operates as follows.

In the initial position, the toe of the elbow 2 lies on the soil of the reservoir (Fig. 1) and is pressed to the face by means of a hydro-: shifter cylinder 12, which.

915752

acting on the slider 8, transmits the force through the finger 16, the conveyor beam 5 and the linear section of the conveyor 3, the Slider 8 is fixed with 5 finger 16 relative to the conveyor beam 5 in such a way that the shoe 10 with the inclined plane 14 of the groove 13 abuts against the tide 6 of the square 2, and the supporting surface 15 on the soil

0 layer. When the plow moves along the inclined guide 1, the coal shavings are removed and the plow line automatically moves after the plow arrival of the linear sections of the conveyor 3 using the hydrotsink of the shifter 12 to the bottom.

In the process of work, if the plow leaves the soil (fig. 3), it is necessary to remove the pin 16 from the holes 17 and 18 in the conveyor beam 5 and the slider

0 8 and turn on the hydraulic cylinder 12 on the extension, Pst dinenny with the slider 8 shoe 10, moving over the soil at the interaction of its inclined plane 14 with the tide 6 of the square 2,

5 raises the downhole part of the installation (the toe of the elbow) above the soil to the required height H, the magnitude of which is limited and controlled by the movement of the slide 8, which in its

Q queue depends on which of the holes 17 will be fixed. slider 8. The slider 8 is fixed with the help of a finger 16 and the holes 18 and 17 in the slider 8 and the conveyor beam 5. The more the slider 8 is pushed towards the face, the larger the H of the angle 2 rises.

As a result, the plow installation

0 moves to a higher level of cutting lines and leaves the soil, after which sections 3 of the plow installation in these areas are brought to their initial position (Fig. 1).

5 In the case of the formation of an ovle in some or other areas of the clearing bottom (Fig. 4), in order to lower the cutting line, it is necessary to remove the pin 16 from the holes 17 and 18

0 in the slider 8 and the conveyor beam 5, turn on the cylinder of the shifter 12 on folding, causing the slider 8 to move away and the plane 14 of the shoe 10 of the shoe 10 will move away from

5 tide 6 of the square 2 and the installation will rest on the ground only with the toe of the square 2 and the conveyor beam 5. As a result of the increase in pressure

Notwithstanding the strength of the sheet on the toe of the square 2 and on the lower plow cutter, as the plow continues to move, the cutting line of the soil cutter decreases and the plow installation descends. After removal of the earth and the removal of the toe of the elbow 2 on the soil of the formation, the slider 8 with the shoe 10 is set in the initial position by means of the hydraulic cylinder of the slide 12 (Fig. 1. For this, when removed from the holes 17 and 18 in the slider 8 and A 1915754

the conveyor beam 5, the finger 16, the hydraulic cylinder 12 is activated for as long as the inclined plane 14 of the shoe 10 kg touches the bow of the angle 2, the movement control of the slide 8 and the shoe 10 is realized by the position of the slide. Slider 8 is operated 10 by means of a finger 16 and holes 17 in slider 8 and 18 in a conveyor beam 5.
