However, in the actual drilling process, due to the influence of complicated formation, the phenomenon of hole collapse is easy to occur, which will lead to the accidents of drill jamming and drill holding. Since the existing threaded-connection-type drill pipes can not be rotated in reverse rotation, which makes the drill pipes with weaker ability of releasing the jamming. Moreover, manual on-site auxiliary disassembling is required, and mechanical automatic disassembling cannot be performed by a drilling rig, which reduces the operation efficiency.
[0003] In the future, the drilling construction underground coal mines will gradually be automated and intelligent. Therefore, when there is an accident of drill-jamming or drill-holding in the hole, the drilling rig needs to judge automatically and perform forward and reverse rotation operations to loosen the debris and release the jamming.

[0038] The working principle of the present disclosure will be described in detail below.
[0039] The two drill pipe bodies are connected with each other in opposite directions by the first connector 1 and the second connector 3, a front extended rod of a drilling rig is connected with a drill pipe body by a threaded connector, and at the same time, the front extended rod of the drilling rig activates the trigger mechanism 5 of the drill pipe body. Under the limiting function of the first sliding-paw guide rail 504 and the second sliding paw guide rail 505, the first sliding paw 502 in the trigger mechanism 5 relatively pushes the second sliding paw 503, and further drives the connection rod 507 to move the pushing rod 602 in the extending mechanism 6 out of the first pushing-rod-positioning-member guide rail. Under the limiting function of the pushing rod 602, the pushing-rod-rotated teeth 605 of the third sliding paw 603, and the third sliding-paw-rotated teeth 606, the pushing rod 602 rotates to push the pushing-rod positioning member 609 forward in the first pushing-rod-positioning-member guide rail 6010, and finally sticks into the second pushing-rod-positioning-member guide rail 6011.

After the connection of the two drill pipes is completed, the thread and the ratchet mechanism are locked in forward and reverse directions.
[0040] The working sequence of the automatic disassembling of the drill pipe is as follows: after the connection of the drill pipe bodies is completed, the drilling rig and the drill pipe bodies are disconnected. The drilling rig and the drill pipe body are connected with each other again, and at the same time, the front extended rod of the drilling rig repeats the above steps, the trigger mechanism 5 makes the extending mechanism 6 push the mandrel 7 again, under the limiting function of the pushing rod 602, the pushing-rod-rotated teeth 605 of the third sliding paw 603, and the third sliding-paw-rotated teeth 606, the pushing rod 602 rotates and makes the pushing-rod positioning member 609 separate from the second pushing -rod-positioning-member guide rail 6011, and enters into the first pushing-rod-positioning-member guide rail 6010 again. Under the force of the third spring 604 and the fourth spring 8, the pushing rod 602 is stuck to retract the mandrel 7, and finally, the mandrel 7 and the spline groove of the ratchet 403 of the drill pipe body are disconnected, the communication connector is separated, and the two drill pipes are locked in one direction with threads. At this time, the drilling rig drives the two drill pipe bodes to rotate in reverse to finish the disconnection.
[0041] Although embodiments of the present disclosure have been shown and described, it will be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made in these embodiments without departing from the principle and spirit of the present disclosure, and the scope of the present disclosure is defined by the appended claims and their equivalents.
