Touch sampler suitable for extraterrestrial celestial body

Abstract

The invention relates to a touch sampler suitable for an extraterrestrial celestial body. The touch sampler comprises a sampling flow guide cover, a pneumatic impact rock breaking mechanism, a flexible spring and the like; wherein the sampling flow guide cover is located at the bottom end of the touch sampler, the gas excitation nozzle is located on the inner side of the sampling flow guide cover,the pneumatic impact rock breaking mechanism is installed on the inner side of the sampling flow guide cover, the flexible spring is installed at the upper end of the sampling flow guide cover, the pneumatic unfolding mechanism is installed at the upper end of the flexible spring; the sample channel is installed in the pneumatic unfolding mechanism, wherein one end is connected with a cavity in the sampling flow guide cover, and the other end is connected with the sample container; the sealing door is installed in the sample channel, and the sample container is fixed to the upper end of the pneumatic unfolding mechanism. According to the invention, the pneumatic impact rock breaking mechanism is used for breaking and stripping the surface of a star, meanwhile, a surface sample is blown into the sample container through gas excitation and transmission, recovery is completed, and the device has the advantages of being short in sampling time, high in star catalogue adaptability, capableof achieving repeated sampling and reliable in sampling.

Description

technical field [0001] The invention relates to a touch sampler and belongs to the technical field of deep space detection. 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, etc., but the sampling reaction force is large and the sampling time is long, which is not suitable...
