Toothholder is provided with the helical blade and end plate, pick-shaped cutter is provided with the toothholder, the end of the pick-shaped cutter is set
It is equipped with hard alloy containment vessel.
Preferably, reinforcement rib is provided with the inside of the cylindrical tube.
Preferably, the junction of the helical blade and end plate and cylindrical tube is provided with reinforcement.
Preferably, the pick-shaped cutter includes pick denticle, pick set and flexible member, the pick denticle and pick
Tooth set connection forms pick body, and the flexible member is arranged on the inner side of pick body.
Preferably, the pick-shaped cutter spread geometry on the end plate is arc.
Beneficial effect using above technical scheme is：The utility model structure provides a kind of higher coal mining of reliability
Machine helix drum, reinforcement rib is provided with the inside of the cylindrical tube, can improve stability when helix drum uses
