Abstract
681.718. Mining-machines. MARCEROU, P. Nov. 3, 1949, No. 28135/49. Class 68(i) A rock-cutting machine comprises a platform 1 slidably mounted on guidetubes or rails and having formed on it a pivot 7 about which can rotate a platform structure 6, 8, 13; 14 and 16 on which is mounted a motor 9 that can, through a reduction gear box, rotate a cutter bar- 19 the outer end of which is reduced and supported on the arm 16 of the platform structure in a bearing 17. This reduced end has secured thereto a bevel gear which meshes with the bevel gear of a rotarycutter 23. A screw conveyer 27 behind the cutter bar is driven from said cutter bar. To advance the machine, a drive is taken from the gear box to a winch 37 on platform 8 via a clutch and the winch cable 38 passes forward over at least one fixed pulley to return and be anchored on the platform 1. The platform structure can be rotated through a right angle by a hand rotated pinion 42 meshing with a rack quadrant 41 on the platform. In use the loader part starts parallel with the rock face and the platform is rotated towards the face. The cutter 23 penetrates the face first and is of such a size as to clear a passage for the arm 16 and then the cutter bar cuts away the face. This rotation of the platform continues until the cutter bar 19 is perpendicular to the tubes and the machine is then hauled along the tubes which are formed of joined-together short tubular lengths. Bolts 48 projecting through slots 47 in the plate 8 contact the inner sides of the tubes 3, 4 to take up rotational thrust during the advance of the machine along the rails. For cutting blocks in one operation two such machines may be assembled on guide tubes in superimposed relation and may drive a third bar cutter spaced between the ends of the bar cutters of the two machines.
