Small celestial body integrated sampler with grinding and clamping functions

Abstract

The invention relates to the field of spaceflight, in particular to a small celestial body integrated sampler with grinding and clamping functions. The sampler comprises a clamping sampler, a grindingsampler, a sample packaging container and a depth camera. A clamping motor is used for driving a ball screw nut and a lofting push rod to do reciprocating motion, a connecting rod drives a clamping jaw to be opened and closed, and sample clamping and synchronous sample feeding are achieved. The grinding motor drives the metal milling cutter assembly to rotate at a high speed to achieve kinetic energy storage, and samples are ground, sampled and conveyed after making contact with a star catalogue. Sampler pose detection is synchronously achieved by arranging a grinding sampler contact switch.The grinding and clamping integrated design is adopted, the sampling capacity of various targets such as star catalogue weathered layers, rock powder and rock blocks is achieved, sample lofting is completed while sampling in various modes is achieved, the structure is compact, and no additional mechanism is needed.

Description

Technical field [0001] The invention relates to a sampler. Background technique [0002] Small celestial bodies (including asteroids and comets) contain a lot of information on the formation and evolution of the solar system and rich minerals, which have extremely high scientific and economic value. Through the detection of small celestial bodies, we can have a deeper understanding of small celestial bodies and provide clues for humans to explore the formation and evolution of planetary systems. Sampling and research of small celestial bodies can provide a comprehensive and in-depth understanding of a series of characteristics such as soil characteristics, orbital characteristics, surface environment, temperature changes, etc., and lay the foundation for subsequent development and utilization of small celestial bodies.

Problems solved by technology

[0003] The surface of small celestial bodies is in microgravity, and the samples will be suspended or scattered during sampling, making it extremely difficult to collect and package samples

At the same time, the form of samples on the surface of small celestial bodies is uncertain, and may contain regolith, rock powder, rock blocks and other substances, which puts higher requirements on the sampler of small celestial bodies, and traditional sampling mechanisms are difficult to meet the requirements of small celestial bodies. Sampling tasks for multiple sample formats in microgravity

At present, there are few studies on small celestial body samplers, and most samplers are only designed for specific media. For example, the sampling mechanism SD2 used in the Rosetta detector developed by ESA adopts a drilling scheme, which is suitable for small objects with soft surface media. Celestial sampling
