Description

The invention relates to plow installations for underground coal excavation, namely, to its executive body, a string.

The aim of the invention is to increase work efficiency by simplifying chip thickness adjustment and the possibility of using a one-way mode of operation.

Figure 1 shows the pitch configured to the maximum chip thickness for the shuttle mode of operation, top view; figure 2 - the same, the view from the side of the slab; in FIG. 3 - the same, tuned to the minimum chip for a person — 15 of the operation mode is performed in pairwise work, top view; figure 4 - installation stops 9 in the grooves 8: a-W,

7, the previously removed stop 9 is installed and the fixed body 1 is attached. The plow is attached to the traction chain by means of trailers 11 and supplied with a removable bass arm 12 when tuning for one-sided mode of operation. For example, take seven notches 8 and denote them with letters,

&, B. -R, g, e,) 1c (Figures 2, 6, and 7).

In FIGS. 3 and 4, we denote min — the thickness of the produced chips is minimal, and max is the maximum thickness of the obtained chips.

-e The stops 9 are installed in the grooves 8 of the guide 7. The locations of the stops 9 are shown in FIG. 2: b Q

the same, set to the minimum chip for single-sided operation, top view; on fig.Z - the same, front view; 6 and 7 - the same, set on the minimum side for one-way operation, top view; Fig.8 - section A-Anafig.6 in Fig.9 - section BB in Fig.7.

The plow consists of two one-sided bodies 1, which in the lower part have unregulated support elements 2 and stripping knives 3 ahead of time, and in the upper part - cutters 4. Knives 3 and cutters 4 are placed on bodies 1 for working in opposite directions. The body 1 is rigidly fixed at the ends of the frame 5, which is made sectional. The frame 5 is connected to the conveyor plate 6, which is also filled with a sectional one. Between the housings 1, a guide 7 is installed, with grooves 8 equally spaced along its length and two adjustable stops 9, on which is placed a symmetric movable body 10 with cutters 4.

The grooves 8 are made in the lower part of the guide 7 and serve to install the stops 9 (Fig. 8). The step between the slots 8 is made a multiple of the length of the movable body 10. The movable body 10 cannot come out of the guide 7, since the stops 9 between which it is located prevent this. The stops 9 are arranged to be symmetrically and asymmetrically positioned relative to the middle of the guide 7. When the movable body 10 is mounted on the guide 7, the movable body 10 moves from the end of the guide 7 (with the fixed case 1 detached and the support 9 removed from this side), and

after its installation on the guide

the mode of operation is performed by the pair-wise installation of the stops 9 into the grooves 8: a –Z,

7, the previously removed stop 9 is installed and the fixed body 1 is attached. The plow is connected to the pulling chain by means of trailers 11 and provided with a detachable shoe 12 when tuned to one-way operation. For example, take seven notches 8 and denote them by letters

&, B. -R, g, e,) 1c (Figures 2, 6, and 7).

In FIGS. 3 and 4, we denote min — the thickness of the produced chips is minimal, and max is the maximum thickness of the chips produced.

Plow setting for shuttle

the mode of operation is performed by the pair-wise installation of the stops 9 into the slots 8:

-e The stops 9 are installed in the grooves 8 of the guide 7. The mounting locations of the stops 9 are shown in Fig. 2: b - Q for maximum chips; J- a - for the average; a-f-dl minimum. The plow for the shuttle mode, configured for maximum chips, is shown in FIG. 1, for minimal chips, in FIG.

The plow setting for one-way operation is carried out by installing two stops 9 in the grooves 8, for example in the grooves a-g, 5-g, E-g, 1 -, (Fig. 2, 6 and 7). When working in the other direction, these will be, respectively, stops in the grooves f-a, e-Q, o-a, i-o, B-a. Figure 4 shows the plow configured for one-way operation, with

focus 9, set on the minimum chip in the groove a (maximum chip is shown conventionally). The minimum chip is provided by placing the stop in the groove q ,, max - stop

In the groove, intermediate chips are provided with stops installed in the grooves & & , g. When the plow is working in the other direction, the corresponding minimum chip is provided by placing the abutment in the groove of the TC, and the maximum - the abutment into the groove of &. At the same time, the removable shoe 12 is moved to the opposite fixed case accordingly.

The chip thickness adjustment mechanism is provided due to the fact that the plow in the working position is rotated relative to the eabo by 3-5. So,

for example, in the USW2.60.00.000 pilot plane, during the shuttle mode, chips from 55 to 85 mm can be provided. This adjustment range can be further expanded by varying the pressure of the hydraulic system of the hydraulic shifter.

The plow can be operated in shuttle mode (Figs. 1 and 3). The plow moves to one side and then to the other side, removing the coal chips and loading them onto the bottomhole conveyor. The conveyor plates are located on the plow conveyor plate and are conventionally not shown.

The plow can also be operated in a one-way mode (Fig. 4). The plow removes and loads the coal chips when moving in one direction, and when moving to the other side, the shoe 12 is used to idle, moving the plow without removing the coal chips.
