Disc cutter cutting sampling and air blowing sample delivery type asteroid surface star soil sampler

Abstract

The invention discloses a disc cutter cutting sampling and air blowing sample delivery type asteroid surface star soil sampler, and belongs to the technical field of asteroid detection sampling. The asteroid surface star soil sampler solves the problems that an existing planet surface star soil sampler lacks a guiding effect, so that the motion trail of a sampled product is not easy to control, and the power consumption of the sampler is high. A gas cylinder, a footage mechanism and a return cabin are respectively fixed on a detector main body, a sampling mechanism is communicated with a sample container through a sample conveying pipeline, the top of a cover body is communicated with the sample conveying pipeline, two outer rotor energy storage motors are correspondingly fixed in the cover body through two motor bases, two disc cutters are correspondingly, coaxially and fixedly connected to the two outer rotor energy storage motors, a plurality of upper nozzles are inserted into a side wall at the upper part of the cover body and run through an inner cavity of the cover body, a plurality of lower nozzles are inserted into a side wall at the lower part of the cover body and run through the inner cavity of the cover body, and each nozzle is communicated with the gas cylinder through a gas pressure pipe respectively.

Description

technical field [0001] The invention relates to a disc cutter cutting sampling and air blowing type asteroid surface soil sampler, which belongs to the technical field of asteroid detection and sampling. Background technique [0002] Detecting asteroids and obtaining soil samples on their surfaces will help to study the material composition of asteroids, and is of great significance to exploring the origin of the solar system and developing space resources. Asteroids are classified according to their constituent materials, including carbonaceous asteroids, silicon asteroids and metallic asteroids, and the hardness of the rocks is different. Affected by space weathering, the surface morphology of asteroids is complex, and the rocks have different shapes and particle sizes. Therefore, the sampler must have the ability to adapt to different star soils. In the prior art, because the surface of the asteroid is a microgravity environment, the trajectory of the sample is not easy ...
