A Lunar Shallow Sampling Tool with Functions of Order Preservation and Encapsulation

Abstract

The invention relates to a lunar shallow sampling tool with the function of keeping order and encapsulating, comprising a cutting head, a bottom connecting head, a bottom encapsulating sheet, an encapsulating inner tube and an encapsulating outer tube, the encapsulating inner tube is slidingly sleeved on the In the package outer tube, a compaction plunger is installed in the package inner tube, and the compaction plunger is connected to the top connector on the top of the package inner tube by a spring; the bottom package piece is installed at one end of the bottom connector, The cutting head is installed on the other end of the bottom connector; one end of the bottom connector is installed on the bottom of the packaged outer tube; before sampling, the packaged inner tube part is located in the bottom connector and the bottom package After sampling, the package inner tube slides out of the bottom connector along the package outer tube to close the bottom package chip. The invention integrates the components with the functions of order preservation and encapsulation at the head position of the sampling tool, which can effectively ensure the collected lunar soil bedding information when the shallow layer of the lunar soil is sampled.

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...
