Floor cutter bit |
摘要 |
A floor cutter bit for a coal plough has a cutter body which supports a floor cutter plate and a coal-face cutter plate. The two cutter plates are made of hard metal, and have respective cutting edges. The cutter plates are soldered into respective apertures in the cutter body. The cutting edge of the floor cutter plate extends the entire length of the floor cutter plate, and the floor cutter plate extends over the entire width of the cutter body. The base of the coal-face cutter plate adjoins the upper side of the floor cutter plate thereby defining an L-shaped cutter plate configuration. The depth of the floor cutter plate, at least in the region where the two cutter plates meets, is greater than about 15 millimeters.
