摘要： A cutter bit adapted to be fixed onto a working surface of a rotating drum of a milling, planing, mining or reclaiming machine is provided. The body of the cutter bit is generally formed of a hardened steel, the cutting surface may be a diamond composition fixed in a step in the upper end of the cutter bit. The cutter bit includes a cutting surface, and the cutting surface may include non-parallel side edges and an upper cutting edge parallel to a lower edge. The lower edge may be any length sufficient to inhibit unintended angular displacement of the cutting surface during operation of the working surface. Alternatively or in addition, the cutting surface may be defined by three edges to allow the cutting surface to be removed and repositioned in at least a second orientation.

摘要： A cutting bit for a bit assembly secured to a cutter head includes a cutting end, a shank extending along a bit axis, and a shoulder positioned between the cutting end and the shank. The shoulder includes an outer edge defining a perimeter, a shoulder end surface defining a shoulder plane, a first inclined surface and a second inclined surface. The first inclined surface is positioned between the outer edge and the shoulder end surface. The first inclined surface extends along the perimeter and is oriented at a first acute angle relative to the shoulder plane. The second inclined surface is positioned between the shoulder end surface and the first inclined surface. The second inclined surface is oriented at a second acute angle relative to the shoulder plane, and the second acute angle is smaller than the first acute angle.

摘要： A method of controlling a shearer is disclosed. The shearer may be configured to travel along a longwall face to extract material with a first cutting drum and a second cutting drum. The method may include setting a first cutting profile including a plurality of desired positions (Di) to be approached by the first cutting drum in a first travel direction (E). Further, the method may include determining a plurality of actual advancing vectors (vi) indicating a change of a position of the shearer resulting from advancing the shearer towards the longwall face. The method may also include determining a plurality of shearer orientations (Oi) along the longwall face. In addition, the method may include generating a second cutting profile to be approached by at least one of the first cutting drum and the second cutting drum in a second travel direction (F) of the shearer.

摘要： A mounting block assembly and method for assembling is disclosed. The mounting block assembly may comprise a mounting block and a toolholder. The mounting block may include a flighting portion, a mounting portion and a protrusion. The mounting portion defines a first bore that is configured to receive a toolholder. The toolholder includes a generally cylindrical sidewall that defines an axis and defines a second bore that is configured to receive a stem of a cutting bit. The sidewall includes a pair of radially outward extending prongs that define a first recess between the prongs. The first recess is configured to interlockably receive the protrusion when the toolholder is disposed in the mounting portion, wherein the interlocked configuration of the toolholder and the mounting block inhibit rotational movement of the toolholder about the axis.

摘要： A tool holder is disclosed for use with a milling drum. The tool holder may have a cylindrical body defining a first end and a second end, the first end configured to be received within a tool mounting block of the milling drum, the second end configured to receive a cutting bit. A flange may be located between the first and second end with respect to an axial direction, and a first bore, with a first opening defined by the second end and extending towards the first end. A frustoconical portion may be located between the flange and the first end with respect to the axial direction and a cylindrical portion located between the flange and the first end. At least one radial opening may pass through at least the wall of the cylindrical portion to intersect or be open to the first bore.
