Abstract

The invention relates to a moon shallow layer sampling tool with sequence preserving and packaging functions, which comprises a cut-in cutter head, a bottom connector, a bottom packaging sheet, a packaging inner tube and a packaging outer tube, the packaging inner tube is sleeved in the packaging outer tube in a sliding manner, and a compaction plunger is arranged in the packaging inner tube. Thecompaction plunger is connected to a top connector at the top of the packaging inner tube through a spring. The bottom packaging sheet is installed at one end of the bottom connector, and the cut-in cutter head is installed at the other end of the bottom connector. One end of the bottom connector is installed at the bottom of the packaging outer tube. Before sampling, the packaging inner tube is partially located in the bottom connector and opens the bottom packaging sheet, and after sampling, the packaging inner tube slides along the packaging outer tube and moves out of the bottom connectorto close the bottom packaging sheet. According to the invention, the assembly with order preserving and packaging functions is integrated at the head position of the sampling tool, so that the acquired lunar soil stratification information can be effectively ensured during lunar soil shallow layer sampling.

Description

technical field [0001] The invention relates to the related technical field of lunar exploration shallow sampling, in particular to a lunar shallow sampling tool with the functions of order preservation and packaging. Background technique [0002] One of the most important and distinctive tasks of lunar exploration is to selectively collect various types of lunar samples with great scientific value on the lunar surface. The collection of lunar samples in lunar exploration can be traced back to the Apollo era. The major achievements of the Apollo lunar landing program are reflected in the collected lunar samples, as well as a large number of new discoveries made around these samples in the world after half a century of research. . A total of 381.7Kg of lunar samples were recovered during the 6 Apollo lunar exploration activities, of which about 24Kg were samples with particles smaller than 1cm. Most of these samples were subjected to preliminary particle size sorting at John...
