Description

Application for the preparatory workings of the tunneling machine, the executive body of which moves along an arc of a circle, is already known.

A distinctive feature of the proposed heading machine of this type is the use of two horizontal bars installed at their ends, normally to them, of two breaking rods as an executive body. Such a structure makes it possible to treat the entire breast at the same time.

FIG. 1 and 2 schematically depicted in two projections the device of the proposed heading machine.

The heading machine as an executive body has two horizontal bars 7, connected at the heads, and installed on the ends of the bars, normally for them, two breaking rods 2.

When the cutting machine is in operation, 3 bars / describe the arc and, crashing into the face, the coal strip falls off simultaneously across the entire chest of the bottom.

Repulsed coal falls on a semicircular metal shield 5 attached to the frame 6 of the combine.

From shield 5, chain 7, provided with scrapers, coal is supplied to longitudinal conveyor 8. Chain 7 and conveyor 8 are driven by an electric motor .9 mounted on the frame 6 of the combine and transmitting rotation to the drive stars.

Conveyor 8 transfers coal to material handler 70, which distributes coal to trolleys 77.

Subject invention

The tunneling machine for preparatory workings, the executive body of which performs a movement along an arc of a circle, is so tied that, in order to process the entire breast at the same time, one side. As an executive body, two horizontal bars were used and installed on their ends, normally to them, two breaker bars.
