Abstract

The invention provides a multifunctional lunar surface sample collecting and packaging apparatus, which belongs to the technical field of aerospace engineering. The invention aims to overcome the problems of complex motion and great implementation difficulty of a conventional lunar surface sample collecting and packaging apparatus during sampling due to a great size, large mass and high power consumption of the conventional lunar surface sample collecting and packaging apparatus. The multifunctional lunar surface sample collecting and packaging apparatus comprises a motor, a sampling assembly and a packaging assembly; the sampling assembly comprises a spiral feeding shaft, a spiral sampling blade, a shell, a central gear shaft, an outer tooth ring, an armed lever sleeve, a shaft coupling, a planetary gear group, a reducer and an L-shaped armed lever; the packaging assembly comprises K dialing pieces, an over-running clutch I, an outer ring, a sample barrel, a sample barrel connecting ring, N guide posts equipped with springs, N guiding unthreaded holes and an over-running clutch II, wherein K and N are both positive integers. According to the invention, spiral conveying and soft bag stay rope sealing modes are employed, the apparatus is driven by a single motor to realize collection and primary packaging of a surface lunar soil sample, a packaging structure is simple, and a shape is well maintained. The multifunctional lunar surface sample collecting and packaging apparatus is used for sample collection in a space environment.

Description

technical field [0001] The invention relates to a sample collection and packaging tool in a low-gravity environment on the surface of the moon, and belongs to the technical field of aerospace engineering. Background technique [0002] The lunar exploration project is an important part of my country's aerospace industry. After landing on the moon, a series of scientific research projects will be carried out on the moon. Among them, the surface sample collection and packaging device is used as a component on the lunar lander that directly contacts with the lunar soil. Capabilities have extremely important requirements. Countries around the world today mainly collect samples from the surface of extraterrestrial celestial bodies by forceps, rakes, and shovels. After collecting samples, they are first transferred, then put into sample containers, and then packaged; In the cosmic environment, it is difficult to reliably realize complex actions such as sample collection, transfer...
