The longitudinal axis NE 9 and shank 11 are disposed at an acute angle to each other. In the straight sections, the pistons of the MCC 6 are installed in the middle position. To move the plow down, MCC 6 is switched on. In this case, the fingers 8 move in the grooves 10 NE 9, the upward deflection of the shanks 11. As a result, the BFV 1 tends to turn down, and the plow separates the coal with the ledge down. Upon the subsequent supply of LCS 1, the elements 4 are also empty. The height of the step formation is adjusted by placing the pistons of the MCC 6 in intermediate positions. To ensure the movement of the plow up, MCC 6 is included in the reduction. In so doing, the plow begins to separate the angle above the elements 4, and an armpit is formed.

Description

The invention relates to the mining industry and can be used in plow units, which are controlled over the soil of the formation by varying the angle of inclination of the conveyor rod by hydraulic control cylinders.

The purpose of the invention is to improve the control accuracy of the plow over the soil of the reservoir by rotating the linear sections of the conveyor with plow guides relative to the hinges located on the side of the developed space due to an increase in the range of movement of the control hydraulic cylinders at a constant vertical movement of the plow.

FIG. 1 shows a plow assembly, side view; figure 2 - section aa in figure 1.

The plow unit consists of linear sections of the conveyor 1 with guides 2 and squares 3 for a plow (not shown), support elements 4, hinges 5 connecting linear sections of conveyor 1 with support elements 4, control cylinders 6, pivotally connected to support elements 4, the rods 7 of which are provided with fingers 8 and pivotally connected with guide elements 9 with grooves 10, tails 11 with grooves 12, hydraulic cylinders 13 for conveying the conveyor, connected by hinges 14 with supporting elements 4, and hinges for 15 sWarping 16 mi support frames 17.

Plow unit works as follows.

When the plow is moving on relatively straight lines of soil of the formation, the pistons of the control hydraulic cylinders 6 are set to the middle position. Improving the installation accuracy of the pistons of the hydraulic cylinders 6 of the control in the adjacent position is achieved due to the fact that the longitudinal axes of the grooves 10 in the guiding elements 9 rigidly connected to the supporting elements 4 and in the shank 11 rigidly connected to the linear sections conveyor 1, located at an acute angle to each other, equal to 10 - 15 °. Therefore, with relatively small vertical movements associated with the shanks 11 of the linear sections of the conveyor 1, which is due to the location of the hinges on the side of the developed space, the corresponding movement of the fingers 8 of the rods 7 of the hydraulic cylinders b in the slots 10 of the guide elements 9 much bigger. The delivery of the linear sections of the conveyor 1 to the bottom is carried out as a result of the addition of the hydraulic cylinders 13, since the rods of the hydraulic cylinders 13 by the hinges 15 are connected to

the bases of the 16 sections of the support 17, which are in the expanded state, and the bodies of the hydraulic cylinders 13 by the hinges 14 are connected to the supporting elements 4. After the stroke of the hydraulic cylinders 13 is exhausted, the projections from the sections of the support 17 are alternately removed and the bases of the 16 sections of the support 17 move to the conveyor 1 due to the expansion of the hydraulic cylinders 13.

In order to ensure the movement of the plow down from the initial position, the control hydraulic cylinders 6 are engaged on the expansion. In this case, the fingers 8 connected with the rods 7 of the hydraulic cylinders 6 of the control 6 move in the direction of the bottom in the grooves 10 of the guide elements 9, the upward deflection of the shanks 11, since the longitudinal axes of the grooves 10, 12 in the directional elements 9 and the shanks 11 are located at an acute angle to each other, with the central position of the pistons of the control hydraulic cylinders 6, the front parts of the slots 1.2 in the shanks 11 are located below the slots 10 in the guide elements 9. As a result, the linear sections of the conveyor 1 tend to turn down along with the guides 2 and the angle bracket E 3 plow. Due to this, the plow, while moving along the guides 2, separates coal with a ledge down. With the subsequent supply of the conveyor 1 and slaughter using hydraulic cylinders; 13, the front portions of the support members 4 go down along with the linear sections of the conveyor 1, the guides 2 and the squares 3 for the plow. The height of the ledge formed in the soil of the formation can be adjusted by setting the pistons of the control hydraulic cylinders 6 to intermediate positions, and the installation accuracy is increased due to the increased stroke of the pistons of the control hydraulic cylinders 6.

To ensure that the plow moves upward from the initial position, the control hydraulic cylinders are turned on. In this case, the fingers 8 move in the slots of the guide elements 9 towards the developed space, downward deflection of the shanks 11. The linear sections of the conveyor-1 rotate relative to the supporting elements 4 around the hinges 5, and the guides 2 with squares for the plow rise above the soil of the formation. Thanks to this, the movement in its movement

guide 2 separates the coal above the support planes of the support elements 4, forming an earth on the soil of the formation. When the conveyor 1 is subsequently fed to the bottom, the front parts of the supporting elements 4 are raised onto an excavation shaft and the rod begins to deviate upward from the initial position. Behind

Due to the increased stroke of the pistons of the control hydraulic cylinders 6, the accuracy of working out intermediate control commands is also improved when the plow unit moves upwards.
