Embodiment Construction
[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] In an embodiment of the present invention, the drilling device of the present invention mainly includes two parts: a drill bit and a high-frequency percussion auxiliary drilling mechanism 7 connected with the drill bit. like figure 1 As shown, it is a specific embodiment of the high-frequency percussion auxiliary drilling mechanism 7 . In this embodiment, the high-frequency impact auxiliary drilling mechanism 7 mainly includes a connecting cylinder 1 , a high-frequency vibration generator and a converter, and the high-frequency vibration generator and the converter are both arranged in the connecting cylinder 2 . The converter converts the high-frequency mechanical vibration generated by the high-frequency vibration generator into high-frequency low-amplitude impact and transmits it to the drill bit. The connecting cylinder 1 is arranged...
