Abstract

The invention provides a self-sweeping laser twist bit, and relates to the technical field of lunar resource exploration drilling tools. The twist bit solves the technical problems that the cutting efficiency of a drill bit is general and rock debris is difficult to discharge. The self-sweeping laser twist bit comprises a twist bit body, a self-sweeping device, a mixing device, a laser assembly and a light transmitting assembly; the laser assembly is arranged in the mixing device; the mixing device is arranged in the twist bit body and is used for grouping and guiding laser beams emitted by the laser assembly; the light transmitting assembly is arranged on a light transmitting hole of the twist bit body and is used for transmitting laser; the self-sweeping device is connected with the light transmitting assembly for sweeping the light transmitting assembly; and the self-sweeping device is a self-sweeping device without external power input. The twist bit is used for lunar geological drilling, has the characteristics of high rock breaking speed, high rock debris discharging speed, long equipment service life and high drilling efficiency, and is suitable for the air-free and water-free moon.

Description

technical field [0001] The invention relates to the technical field of lunar resource exploration drilling tools, in particular to a self-sweeping laser twist drill. Background technique [0002] With the rapid development of aerospace technology, human exploration of the universe continues to deepen. Our country is still in its infancy in the field of design and research of unmanned autonomous drilling devices for planetary exploration, and key technologies are in urgent need of breakthroughs. The understanding of the moon itself, such as the composition of the lunar soil and the utilization of resources, urgently needs the support of new drilling technologies. [0003] In terms of lunar resource exploration, the rotary drilling method commonly used at home and abroad is completed by using a drill bit with a rising helical groove inlaid with welded carbide. This kind of drill bit is because the drill bit and the helical flute cannot be connected completely correspondingly...
