Wave helical blade cylinder

The utility model provides a wave helical blade cylinder, is applicable to the drum shearer. It is including section of thick bamboo hub, helical blade, end plate, pick type pick. A section of thick bamboo hub be cylindrical, a section of thick bamboo hub head has welded the end plate, has welded two helical blade on the section of thick bamboo hub and has constituted the double-end cylinders, arranges the pick type of installing pick on end plate and the helical blade. The helical blade outer fringe be the wave, on same transversal, a helical blade's peak corresponds another helical blade's valley bottom, makes total thickness of cutting of each transversal the same, pick type pick in order formula configuration install peak and the valley bottom department at helical blade to realize different mounting heights. The broken coal of this cylinder is efficient, and the lump coal rate is big, and simple structure, installation convenient operation.
