摘要： A cutting bit assembly for a mining machine includes a holder having a first surface, a second surface, and a bore extending therebetween, and a bit having a first end and a second end. The bit further includes a tip, a shank, and a shoulder positioned between the tip and the shank. The shank is positioned in the bore of the holder and defines a shank axis. The shoulder engages the first surface of the holder. The shank includes a projection adjacent the second end. The cutting bit assembly also includes a retainer having a groove and a resilient member. The groove engages a portion of the projection. The resilient portion engages the second surface of the holder and biases the retainer along the shank axis and away from the holder.

摘要： A cutter head for a mining machine includes a drum defining a drum axis with a drum plane extending perpendicular to the drum axis. The cutter head includes a plurality of cutting bit assemblies secured to an outer surface of the drum proximate a first end. Each cutting bit assembly includes a block and a bit. The bit includes a tip configured to engage a mine surface. The bit defines a bit axis, and the bit axis defines a first lean angle relative to the drum plane. The plurality of cutting bit assemblies includes a first series having four first bits, a second series having two second bits, a third series having two third bits, and a fourth series having two fourth bits. Each of the first bits includes a first tip and defines a first bit axis oriented at a first lean angle relative to the drum plane. The first lean angle is between about 60 degrees and about 75 degrees.
