  • Patent number: 11920437
    Abstract: A speed-enhancing drilling tool includes an upstream drill string (10), which has a drive motor and a first driving rod coupled therewith, a downstream drilling bit; and a percussive device connected between the upstream drilling string and the downstream drilling bit. The first driving rod extending axially and the drive motor are configured to drive the first driving rod in rotation. The percussive device has a rotary driving part having an upper end engaged with the first driving rod to rotate together therewith; and a rotary working part having an upper end engaged with a lower end of the rotary driving part and a lower end connected with the downstream drilling bit. The rotary working part can be driven by the rotary driving part to rotate about its axis, and axially movable relative thereto; and a percussion generating part arranged around the rotary working part.
