The invention relates to equipment for mechanizing coal mining on very thin steep and oblique seams.

The aim of the invention is to increase the reliability of operation by preventing water from flowing into the cable entry.

FIG. 1 shows a combine, top view; in fig. 2 is a view A of FIG. one.

The coal combine consists of an executive body in the form of two cutting drums 1 and 2 located at the ends of the housing 3, rotary handles 4 and 5, gearbox 6, trailer device 7, electric motors C and 9, cable distribution block 10 inlets, plug disconnector 1i, connecting flanges 12 and 13 of the block of inputs of cable ends in the motor cover 14 of the block of inputs with the emergency button Stop 15, cover 16 of the block of inputs with a socket for plug disconnector, power cable 17, acoustic signal radiator 18 and cable clamp 19, two distribution chambers 20 and 21.

The operation of the combine and its maintenance are carried out as follows.

For operation in the left-hand bottomhole, the cable 17 is connected via a hitch 7, at the end of which a cable clamp 19 is installed to prevent the cable from being pulled out during operation. The plug disconnector 11 is installed with a cover 1.6 in the socket of the distribution chamber 21 with the socket down, the cable is introduced into it by a loop at the bottom (figure 2), which completely prevents the ingress of water flowing through the cable into the internal cavity of the disconnector.

From the distribution chamber 21 power cable rings through the standard distribution pads on.

The internal channels are supplied to the Electric Motors 8 and 9, which are in contact with the cable distribution block 10 of the inlets by means of connecting flanges 12 and 13 with an explosion-proof connection. The cap 14 with the emergency button Stop 15 is installed in the socket of the distribution chamber 20 and has a cable outlet to the acoustic emitter 18 of the signal, which warns the staff about the activation of electric motors and the start of rotation of the cutting drums 1 and 2

The distribution unit 10 and the acoustic signal emitter 18 are fixed on the housing 3 of the gearbox 6. The trailer, the device 7 is fixed on the rotary knob 5.

When reassembling the combine to the right bottom, the hitch 7 together with the cable 17 is re-installed on the rotary handle 4, and the cover 14 with the Stop button 15 and the cover 16 with the plug disconnector 11 are relocated in the slots of the distribution block 10 inlets. In this case, the bolts 1, together with the plug disconnector, unfold to .180 and occupy the operating position with the socket of the plug disconnector down. Inside the cable distribution box 10 inputs and in the distribution chambers 20 and

j21 is made by matching the ends of the power cable. The acoustic signal emitter 18 remains in place.
