Abstract
The invention discloses a drill rod with cutting teeth on a helical blade. The drill rod comprises a drill rod assembly, the cutting teeth and tooth seats. The tooth seats are welded to the helical blade, the cutting teeth are installed in the tooth seats and can be pickax-shaped cutting teeth or knife-shaped cutting teeth, and the tooth seats matched with the pickax-shaped cutting teeth and the knife-shaped cutting teeth are different. When the drill rod rotates, the cutting teeth cut coal rock along with rotation of the helical blade. Only one kind of cutting teeth can be arranged on the same drill rod or two kinds of cutting teeth can be arranged on the same drill rod simultaneously, when the two kinds of cutting teeth are arranged simultaneously, the cutting teeth are arranged at intervals. The rotation radiuses of motion trails of tooth tips of the cutting teeth are the same, and the chamfers and the elevation angles of the cutting teeth are the same. The elevation angles and the chamfers of the cutting teeth of the drill rod with different rotation directions and screw pitches of helical blades are different. With the cooperation with a common drill rod, the cutting teeth on the helical blade cut the collapsed coal rock, collapsed drill holes are restored, a buried and pressed drilling tool is relieved, coal rock conveyance is achieved, the problems that in the working process of an auger type coal miner, drill holes collapse, coal conveyance is blocked, and the drilling tool is buried and pressed can be solved, coal mining efficiency is improved, and high practicality is achieved.
