Abstract

1316260 Mineral-mining machines; planing road surfaces GREENSIDE MACHINE CO Ltd 25 Aug 1970 [5 Aug 1969] 39256/69 Headings E1F and E1G A rotary, drum type cutter head for a mining, tunnelling or road-planing machine comprises a core structure 1 having an annular periphery and cutter pick-carrying, arcuate, plate segments 4, which are releasably interconnected and fixed in position against the annular periphery of the core structure to form a shell cladding the structure. Interconnection of the segments is by bolted together, abutting, axially extending flanges 7 and the segments are preferably anchored on the structure 1 by projections 2 on the structure 1 entering holes 3 in the segments 4. Each segment can also have a flange 5 which can be secured to a flange formed of flange elements 10 located at one end of the structure when it is of cylindrical form. A pick-carrying, circular front plate 12 can be secured to the flange 7 and 10, the flanges 7 being then preferably set back from the adjacent edges of the segments. Keys 11 on the plate 12 enter gaps between adjacent flanges 5 of the segments. One or more such drums are used in a tunnelling or mining machine having an arm A rotatable about an axis extending longitudinally of the machine, and means D on the arm for rotatably driving at least one such drum H constructed according to the invention and supported on the arm.
