The invention relates to the technical field of
space exploration, and concretely discloses a
celestial body surface sampling apparatus. The apparatus comprises a motor, a sampling mechanism and a collection box; the sampling mechanism of the
celestial body surface sampling apparatus employs a driving gear and a driven gear which are engaged to drive a driving shaft and a driven shaft which have the same structure for carrying out counterrotating, in order to realize mutual cancel of rotational
inertia, and reduce reaction force for a
detector. A driving
ratchet guarantees the driving shaft tocarry out unidirectional rotation only, the driving
ratchet and a mounting base on the collection box act together in order to realize installation and separation of the motor and the driving shaft,and the sampling mechanism can be flexibly taken and stored.
Drill bits and inclined blower blades are arranged at the front ends of the rotating shafts in order to realize sampling of loose and softsoil and hard rocks. The
celestial body surface sampling apparatus can be used for sampling different landforms on surfaces of nongravitational celestial bodies, and has light weight, small reaction forces for detectors, flexible usage; and the product can satisfy detection demands on nongravitational celestial bodies and minor planets.
