AI Technical Summary
Technical Problem
Problems such as the loss of some samples and unclear sample stratigraphic sequence during the drilling process when sampling soil layers on extraterrestrial planets.
Method used
A magazine-type drill bit for extraterrestrial directional sequence-preserving sampling was designed, including a drill bit and a drill rod mechanism. By setting multiple inner tube components and rotating the sampling port, effective collection of soil samples and clear sequence separation can be achieved.
Benefits of technology
This effectively prevented the loss of soil samples after sampling and ensured the clarity of the stratigraphic sequence of the collected samples.

Abstract
The invention relates to an extraterrestrial directional order-preserving sampling magazine type drilling tool single body, an extraterrestrial directional order-preserving sampling magazine type drilling tool assembly and a sampling method.The extraterrestrial directional order-preserving sampling magazine type drilling tool single body comprises a drill bit and a drill rod mechanism, the drill rod mechanism comprises an outer threaded pipe, a magazine inner pipe assembly and a first connector part, and the magazine inner pipe assembly is coaxially arranged in the outer threaded pipe in a sleeved mode; the first connector part and the drill bit are fixedly connected to the upper end and the lower end of the outer threaded pipe in the axial direction correspondingly and conduct axial limiting on the missile cabin inner pipe assembly, and the missile cabin inner pipe assembly is rotationally matched with the outer threaded pipe or / and the drill bit or / and the first connector part. An inner pipe upper connector is fixed to the upper end face of the missile cabin inner pipe assembly. The missile cabin inner pipe assembly comprises a plurality of inner pipes, the inner pipes are sequentially and fixedly connected in the axial direction of the outer threaded pipe, each inner pipe forms an independent pipe cabin, every two adjacent pipe cabins are separated through a partition plate, and the side wall of each inner pipe is provided with a first sampling opening located in the same side of the missile cabin inner pipe assembly; a plurality of second sampling ports are formed in the side wall of the external threaded pipe.
