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.
