<p>The invention relates to a device for loosening and transporting coal, comprising a inner conveying throughs and inner excavating throughs and a driven peripheral chain haulage guided by means of direction-changing devices, excavating bodies (6) being attached to said chain haulage. The mining bodies (6) have a middle piece (13) and guide pieces (11, 12) articulated thereto by means of pivoting axes (16), one (11) of said guide pieces being mounted in the front and the other (12) being mounted in the back. The pivoting axes of said guide pieces are inclined against each other at a given angle of inclination so that bend-free rotation of the excavating bodies and particularly the guide pieces thereof is ensured in the transition areas from translational to rotational guidance and from rotational to translational guidance in the area of the direction-changing devices.</p> |
