A small celestial body integrated sampler with grinding and clamping functions

Abstract

The invention relates to the aerospace field, and relates to a small celestial body integrated sampler with grinding and clamping functions, comprising a clamping sampler, a grinding sampler, a sample packaging container and a depth camera. Use the clamping motor to drive the ball screw nut and the lofting push rod to reciprocate, and drive the clamping jaws to open and close through the connecting rod to realize sample clamping and synchronous sample feeding; use the grinding motor to drive the metal milling cutter assembly to rotate at high speed to achieve kinetic energy storage , After contacting the star catalog, complete the sample grinding, sampling and sample delivery. The position and attitude detection of the sampler is realized by arranging the contact switch of the grinding sampler synchronously. The invention adopts the integrated design of grinding and clamping, and has the sampling ability of various targets such as star surface weathered layer, rock powder, rock block, etc.

Description

technical field [0001] The present 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. The detection of small celestial bodies can provide a deeper understanding of small celestial bodies and provide clues for human exploration of the formation and evolution history of planetary systems. Sampling research on small celestial bodies can provide a comprehensive and in-depth understanding of a series of characteristics such as the characteristics of its star soil, orbital characteristics, surface environment, and temperature changes, and lay a foundation for the subsequent development and utilization of small celestial bodies. [0003] The surface of small celestial bodies is in microgravity, and the samples will be suspended or scattered during sampling, whic...

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
