Research， trial production and testing of the “Wigen” lunar sampling drill

Abstract:

This paper introduces the research objectives， applicable environment， structure， composition， working parameter calculation， functional tests and drilling experiments of a lunar sampling drill. This drill is expected to provide astronauts on the moon with a lunar exploration drill scheme and prototype that combines manual and automatic operations， enabling multi-site， multi-hole， multi-depth， multi-cycle， multi-variety and high-quality lunar sampling， for relevant departments to select and reference. The development of the "Wigen" sampling drill covers the entire set of supporting devices including special sampling drilling tools， drill rig fixation， and manual control systems， adopting the lifting-type percussive-rotary rock-breaking drilling method. After further improvement， it is also expected to realize the drilling of blast holes， geophysical prospecting holes and anchor holes on the moon， to support tasks such as mineral exploitation and scientific research base construction. The "Wigen" sampling drill reserves matching installation positions， providing preliminary technical reserves for the development of remote-controlled lunar automatic sampling drills or remote-controlled lunar multi-functional automatic sampling drills. The scheme and prototype of this drill can also serve as a reference for the development of Mars sampling drills.
