A star soil pneumatic conveying device for small celestial body sampling comprises a gas supply assembly, a sound velocity spray pipe, an excitation sampler, a sample conveying pipeline and a packaging container, and the gas supply assembly is used for providing two independent gas paths of sampling excitation gas and sampling conveying gas for the excitation sampler; the excitation sampler is used for exciting star soil by adopting gas to form a gas-solid coupling body, and the gas-solid coupling body enters the gas-blowing sample feeding pipeline; a sonic spray pipe is arranged in the excitation sampler and is used for continuously accelerating a coupling body in the sample feeding pipeline to form a continuously accelerated pipe flow; the sample conveying pipeline is used for conveying the gas-solid coupling body to the packaging container; and packaging the container to realize gas-solid separation, and collecting the star soil sample meeting the requirements. Compared with the Eurylius task, the device reduces two links of primary packaging and mechanical arm sample transfer, and improves the efficiency and reliability of on-orbit sampling.

    一种用于小天体采样的星壤气力输送装置,包括:供气组件、音速喷管、激励采样器、送样管道、封装容器,其中:供气组件用于向激励采样器提供采样激励气体和采样传输气体两路独立气路;激励采样器,用于对星壤采用气体进行激励后形成气固耦合体,进入气吹送样管道;激励采样器内设有音速喷管,用于使送样管道内的耦合体不断加速,形成不断加速的管流;送样管道,将气固耦合体输送至封装容器;封装容器,实现气固分离,收集合乎要求的星壤样品。该装置对比欧西里斯任务,减少了初级封装和机械臂转样的两个环节,提升了在轨采样的效率和可靠性。
