[0013] A rotary cone for a full-casing full-rotary drilling machine includes a rotating part 1 and a gear part 2 . The rotating part 1 and the gear part 2 are integrated. The rotating part 1 is roughly ring-shaped. The gear part 2 is formed on the outside of the rotating part 2 and is a ring gear made by processing, which is used to mesh with the external gear to drive the rotating part 1 to rotate. When working, the hydraulic motor 3 starts to drive the reducer 4 to rotate. The reducer 4 drives the driving gear 5 to rotate through the output shaft. The driving gear 5 meshes with the idler 6 to drive the idler 6 to rotate. It drives the entire rotary cone to rotate, and then clamps the casing rotation operation of the full-casing full-rotary drilling rig.
[0014] The rotary cone of the present invention is processed outside the rotating part 1 to form the gear part 2 of the ring gear structure. Structurally, the rotating part 1 and the gear part 2 are integrated without any c...
