FIELD: mechanical engineering, particularly in mineral resource industry.
SUBSTANCE: heading-and-winning machine comprises chassis, bench unit, upper cutting device, conveyer, planetary-and-disc executive tool, displaceable rotation reducer, two executive tool reducers and two distribution reducers. The distribution reducers include body with central starting borers and two arms provided with intermediate and output shafts. Main cutting discs are installed on output shafts. Additional cutting discs are mounted on intermediate shafts so that cutting planes thereof are shifter with respect to main cutting disc planes and discs are partially overlapped one with another. Main and additional cutting disc axes are in single plane transversal to face. Main cutting discs are as close as possible to bench unit.
EFFECT: extended functional capabilities and improved service performance.
