Abstract
The utility model relates to a cutting head of a coal mining mechanism, in particular to a cutting head with impact tooth, which consists of a cutting head body, an inner spraying nozzle, an upper cover of the impact tooth, an impact tooth and an impact tooth base, a rubber tube, an oil distribution plate, an O-shaped ring, a sealing sleeve, a rotary sealing ring, a sealing ring and a main spindle. Wherein, the cutting head body realizes connection with the spindle by use of a spline, the oil distribution plate is arranged on the spindle and fixed on the cutting head body. Moreover, the impact tooth is positioned on an impact tooth piece on the cutting head. The product provides flexible operation; once undergoing a certain resistance, the impact tooth generates a certain axial impact force to impact and break the obstacle. The utility model reduces the producing cost and improves labor efficiency.
