Novel coal mining machine spiral drum

The invention relates to the field of coal mine machinery coal mining machine spiral drums, in particular to a novel coal mining machine spiral drum. The novel coal mining machine spiral drum comprises a transmission part, a cutting part, a mist spraying assembly and an auxiliary structure. Power and motion of a coal mining machine are transmitted to a wheel hub through a square shaft, then the drum is driven by the wheel hub to rotate, a cutting assembly cuts a coal seam, and coaling is completed by a vane. An end disc adopts a detachable hollow split structure, the vane adopts a hollow split structure, and water passing pipes are installed in the end disc and the vane. A set of supporting plates are welded to the outer wall of a drum body, and the integral rigidity of the drum is improved through the supporting plates. According to the novel coal mining machine spiral drum, the overall weight of the drum is reduced, the cutting ratio energy consumption is reduced, the mist spraying effect is improved throug
