Description

The invention relates to mining, in particular, to plow means for the complex mechanization of coal extraction without the constant presence of people in the clearing face.

The purpose of the invention is to increase the efficiency by smoothly adjusting the height of the cutting member.

FIG. 1 shows the scraper construction unit, plan view; in fig. 2 is a section AA in FIG. 1 with the cutting body folded; in fig. 3 - the same with the cutting organ apart; in fig. 4 shows the knot I in FIG. one; in fig. 5 is a section BB in FIG. 4 (with folded cutting organ).

The scraper-round unit includes mechanized lining sections 1, consisting of bottomhole 2 and bulk 3 semi-sections, sectional base beam 4 and scraper edge 5 with bezreztsovy 6 n cutting 7 walls, with end 8 and intermediate 9 sections. At the end sections 8, fasten the lower cutting parts 10 with a cutting tool. The scraperostrug 5 is moved by the drive, the VOLUME STRUCTURE from the drive 11 and the bypass 12 stations located at the preparatory workings, and the TZ traction body.

The sectional base beam 4 is fixed on the base 14 of the bottomhole half-section 2, the support by which the scraperostrug 5 moves. base beam 17.

In Bezreztsov 6 and incisal 7 walls of the end 8 sections of the scraperostrug 5 installed shdrotsilindr; 18 and 19,

The rods 20 of the hydraulic cylinders 18 by means of the rolling support 21 are engaged with a second base beam movable at a height of 17. On the cylinders 19 of the cutting wall 7 of the end sections 8 of the scraper angle 5, the upper cutting parts 22 of the cutting body supporting the cutting tool are fixed with the possibility of longitudinal movement. 23. Upper cutting parts 22: with their back side they rest on supports 24 secured on the end sections of the 8-scraper 5, made in the form of a segment of a ring.

50 5 $ The rod end 25 of the hydraulic cylinders 18 are hydraulically connected to the piston and the cavity 26 of the oppositely located hydraulic cylinders 19, and the piston cavities of the 27 hydraulic cylinders 18 - with the rod end 28 of the oppositely arranged hydraulic cylinders 19 (Fig. 5).

The hydraulic jacks 16 are connected to the control equipment associated with the coal-rock sensors mounted on the cutting tool 23 (the control hardware and the coal-rock sensors are shown).

The scraper-angle unit also has a device for sanding the formation bed (not shown).

Proposed: The scraper post assembly works in the following manner.

In the original procedure, the bottom half-section 2 of the lining 1 is pushed to the bottom, and the half-mounds 3 are pushed to the nda. Yadrodetkrats 16 and hydrocylicdia 18 and 19 occupy the position corresponding to the minimum or maximum reservoir thickness

That is, they are in an open position shifted by Him.

Let us first consider the operation of aggregate, d at the minimum reservoir thickness, when the hydraulic overhead strands 16 and the second 17 directions are in the lower half of Kenya. In the lower position are also the stocks of the hydraulic chains 18 and 19 and the upper cutting parts 22.

When the drive is turned on, the scraperostrag 5 moves through the base beam 4 and the bases of the bottom hole half semi-sections 2 1phi through the base beam 4, and the scraperostry part 10 of the end sections 8 of the scraperostragon from the coal moves along the lava, and the sensors - the rock follows the change in reservoir thickness. At the same time, the scraperostrug 5 is pressed to the chest by the bottom clamps and half sections 2 by means of the base beam 4. The latter and the L-shaped stoppers guide the movement of the scraperostrag 5 along the lava and fix its position relative to the soil and the roof of the seam.

The crushed coal falls on the base 14 of the bottomhole semiperctions 2 of the lining, and during the return stroke, the scraperostrug 5 is delivered last to one or both of the preparatory works.

As the reservoir capacity increases, the coal-rock sensors signal the control equipment of hydraulic jacks t6, which actuates them, due to which the rods of the latter are driven by an appropriate amount, while moving upwards the second base beam 17. At the same time, by means of katzgchy support 2t, respectively The rods 20 of the hydraulic cylinders 18 are advanced. In this case, the pistons of the HYDRO-1SHDINR-18 rise upwards and begin to push the working fluid out of the rod-shaped cavities of the 25th hydraulic fluids 18 into the piston cavities 26 of the GIDocociline 19, the current cavities 28 hydraulic cylinders 19 - into the pores cavities 27 hydraulic cylinders 18; As a result, the rod 29 of the hydraulic cylinder 19 also starts up and upwards, moving the upper part 22 with the punch tool 23, which begins to cut the coal in the enlarged section shch1nbsti reservoir. With a sharp increase in reservoir mobility, control. hydraulic jack 16 is carried out by means of portioners, allowing the second base beam 17 to be raised by an amount not exceeding the maximum possible chip height. In this case, the output of the cutting tool to the new increased

234:

seam thickness is carried out in several passes scraper pit 5.

When the reservoir capacity decreases, the coal-rock sensors signal the control equipment of hydraulic jacks 16, which actuates them, in connection with which the rods of the latter are lowered by an appropriate amount, while moving the second base5 beam 17 downwards, and by means of coils of the support 21 - and the rods of 20 hydraulic cylinders 18. At the same time, the pistons of the hydrocyptic fuel - the wood 18 push the working fluid out of the piston cavities 27 into the rod end.

the cavities 28 of the hydraulic cylinders 19, and from the piston cavities 26 of the hydraulic cylinders 19 - into the rod cavities 25 of the hydraulic cylinders 18. As a result, the upper cutting parts 22

together with the cutting tool 23 - which produces the destruction of coal in the area of reduced thickness of the reservoir. The downhole half-section 2 is supplied to the bottom by hydraulic jacks

advances (not shown) of the obstruction half-section D1, 3,

After exhausting the progress of the sliding of the jacks, the advancing forces make the tightening of the 3 half sections to

downhole 2. Reaming is performed in one section, for example, at the beginning of all even and then odd or vice versa. .
