Abstract

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.

Description

technical field [0001] The invention relates to the technical field of space detection, in particular to a star surface sampling device. Background technique [0002] With the continuous advancement of human space exploration, after realizing the sampling of the moon and Mars, the next step will be to detect asteroids in space. Asteroid detection is of great scientific significance for understanding the formation process of planetary systems and exploring the origin of life, and also provides a scientific basis for the subsequent development of planetary resources. Asteroid surface sampling is an important part of asteroid detection. Due to the characteristics of asteroids such as fast autobiographical period, uncertain surface geological structure, and microgravity, the sampling devices used on the moon or Mars cannot be fully suitable for the detection of asteroids. Designing a sampling mechanism that is small in size, light in weight, able to adapt to different sampling...
