Planet wheel displacement centrifugal directional sampler suitable for extraterrestrial celestial body

Abstract

The invention relates to a planet wheel displacement centrifugal directional sampler suitable for an extraterrestrial celestial body. The planet wheel displacement centrifugal directional sampler comprises a cutter assembly, a displacement assembly, a sample sealing assembly, a separation assembly and a bracket, wherein the cutter assembly is provided with a planet carrier; a plurality of same single-rotation shaft systems are evenly distributed on the planet carrier along the circumference, and a cutter can be installed on each single-rotation shaft system, wherein the single-rotation shaft system is in matched transmission with the sun gear, so that rotation of the sun gear can drive all cutters to rotate through the single-rotation shaft system, sampling of a sampling object can be achieved through rotation of the tools, and the displacement assembly is matched with the cutter assembly to drive the cutter assembly to rotate and transpose. The sample sealing assembly can be used forcollecting a sampling sample obtained by sampling of a cutter, when the sample needs to be recycled, one end of the separation assembly can be disconnected from the other end of the separation assembly through pyrotechnic initiation or electromagnet electrification, and the whole sample sealing assembly carries the collected sample to be transferred into an external recycling container together.

Description

technical field [0001] The invention relates to a planetary gear transposition centrifugal directional sampler suitable for extraterrestrial celestial bodies, belonging to the technical field of planetary sampling. Background technique [0002] Sampling extraterrestrial objects is an important means of deep space exploration. Extraterrestrial celestial bodies, especially small celestial quasars, have very small volume and mass, resulting in very small surface gravity. In an environment with almost no gravity, it is very difficult to achieve long-term landing, and the force exerted by sampling may push the probe away from the star. This feature determines that the sampling on this type of extraterrestrial celestial body must have the characteristics of small reaction force. At the same time, the sampling objects on extraterrestrial celestial bodies have great uncertainty, and may exist in various forms such as powder, gravel particles, and boulders. To ensure the success rat...
