Abstract
The invention relates to mining, in particular to units for connection of rods of drill string of auger, drilling-and-stowing and other machines for hole making with rotary drilling, for instance by coal. Joint unit of rods of drill string includes central cylindrical member at one rod and opening for it at the other one, conjugated to each other cams on both rods with outer cylindrical surface, unit for axial and unit for angular fixation of joint. At the outer cylindrical surface of cams in middle part of conjugation of those circular groove is provided. Unit for axial fixation of joint is arranged as ring with radial protrusions at inner surface.
