Lower bearing and stabilizer；It is all provided with fluted on the inwall of the top connection and lower contact, the two ends of drill string are provided with projection, top connection
With the two ends that lower contact is sleeved on drill string by the interlocking mechanism that projection and groove are formed, and top connection and lower contact pass through pin
Fixed with drill string；The stabilizer set offers card on the outer wall of top connection, and on the top connection outer wall at stabilizer two ends
Groove, Spring Card is arranged in draw-in groove；The inner ring of the upper bearing (metal) and lower bearing is sleeved on the two ends of drill string, is applied on the inwall of overcoat
It is covered with equadag coating, the both sides of overcoat are provided with support rib, and overcoat is arranged on the outer wall of drill string, upper bearing (metal) and lower bearing quilt
It is included in the closing space that overcoat, drill string, top connection and lower contact are formed, and the both sides of upper bearing (metal) and lower bearing are mounted on
Water-swellable adhesive tape.
As a preferred technical solution of the present invention, projection rectangular array arrangement on drill string.
Used as a preferred technical solution of the present invention, the upper bearing (metal) and lower bearing use thrust ball bearing.
Used as a preferred technical solution of the present invention, the pin is four for being symmetrically installed.
Beneficial effect：Compared with conventional art, a kind of rotary drilling guider structure of the invention is novel, design science
Rationally；The both sides of bearing are provided with water-swellable adhesive tape, it is ensured that bearing is hardly damaged；Equadag coating is coated with outer casing inner wall,
Drilling rod is not easy to wear；Connected using concavo-convex interlocking mechanism between joint and drilling rod, increase the stress between joint and drilling rod.
