Abstract

The invention relates to a drilling mechanism for a small celestial body star catalogue, belongs to the technical field of aerospace deep space exploration, and aims at carrying out automatic drillingand sample collection tasks on a small celestial body surface layer sample. A weak-gravitation star catalogue drilling mechanism for deep space exploration adopts an ultrasonic drill for drilling, and can realize small-feeding-force and large-hardness sample drilling; in the drilling process, the samples are concentrated together, and after the samples are drilled to the specified depth, the sample collecting container can be closed. The protection points are a weak gravity star catalogue drilling mechanism design scheme, a working principle, a grounding assembly design and an ultrasonic drilling and sample collection integrated design scheme.

Description

technical field [0001] The invention relates to a drilling mechanism for a small celestial body catalog, which belongs to the technical field of aerospace deep space exploration and is used for automatic drilling and sample collection of small celestial body surface samples. Background technique [0002] In order to explore the mysteries of the universe, humans have carried out a series of detection activities on outer space celestial bodies, among which sample sampling is one of the important detection methods. NASA, ESA and JAXA have all carried out sample sampling detection on small celestial bodies. my country has also conducted preliminary research on the detection of small celestial bodies, including the development of a prototype of a small celestial body automatic sampling mechanism, which can realize in-situ drilling, sample transfer, sample measurement and sample heating on the surface of small celestial bodies. During the drilling process, the efficiency is low, es...
