Abstract

The invention discloses a symmetrical rotary excavating and pneumatic conveying composite sampler suitable for asteroid. The symmetric rotary excavating and pneumatic conveying composite sampler comprises a detector interface, gas pipelines, gas valves, unfolding outer cylinders, unfolding inner cylinders, flexible corrugated pipes, mounting flanges, a sampling front end, a closing channel, a flexible channel, a lower unfolding channel, an upper unfolding channel, a recovery channel and a sample recycling container; wherein the unfolding outer cylinders are connected with the detector interface through a flange structure; the gas pipelines and the gas valves are arranged inside the unfolding outer cylinders respectively; the flexible corrugated pipes are connected with the sampling front end through the mounting flanges; the closing channel, the flexible channel, the lower unfolding channel and the upper unfolding channel are sequentially connected; the sampling front end is connectedwith the closing channel; the upper unfolding channel is connected with the recycling channel, the sample recycling container is connected with the recovery channel; the sample recycling container andthe recovery channel are all positioned inside the detector interface. According to the device, the sampling which is strong in geological characteristic adaptability, low in reaction force, simple and reliable, fast and efficient is achieved.

Description

technical field [0001] The invention belongs to the technical field of deep space exploration, and in particular relates to a symmetrical rotary digging and pneumatic transmission composite sampler suitable for asteroids. Background technique [0002] Asteroids are an important carrier for humans to understand the origin and evolution of the solar system, and carry a wealth of scientific information. Therefore, it is of great significance to sample and return asteroids. However, there are many types of asteroids, lack of understanding of surface geological characteristics, and the surface gravity of asteroids is extremely weak, making it difficult to achieve attachment and fixation. This requires asteroid sampling technology to have the characteristics of strong adaptability to geological characteristics, low reaction force, and rapid sampling. [0003] Sampling techniques commonly used on the moon and Mars include drilling, mechanical arm shoveling, grinding and grabbing, e...
