Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0023] This embodiment provides a sampling and detection tool for extraterrestrial celestial bodies, which is suitable for sampling and in-situ detection of natural or artificial pores of extraterrestrial celestial bodies. Rotary drilling as a technical way of deep sampling faces disadvantages such as long sampling time, large support reaction force, and large mechanical and thermal disturbance to the sample.

[0024] Such as figure 1 and 2 As shown, the sampling detection tool includes: a drive assembly A1, a drive assembly B2, a screw transmission member 3, a housing 4, a sample chamber packaging head 4-1, a knife holder guide groove 4-2, a sampling knife transmission assembly A5, a sampling Knife transmission assembly B6, knife seat 7, sample chamber 7-1, sampling knife groove 7-2, sampling knife 8, infrared spectrum detection sensor 9, pyroelectric p...

Abstract

The invention discloses an extraterrestrial celestial body sampling and detecting tool which comprises a lead screw transmission part, a tool apron and a sampling tool. An output shaft of the driving assembly A is in flat key connection with a lead screw transmission piece, and the lead screw transmission piece penetrates through a through hole in the center of the driving assembly B and is fixedly connected with the drill bit assembly. An output shaft of the driving assembly B is in flat key connection with the sampling cutter transmission assembly A, the sampling cutter transmission assembly A is in spline connection with the sampling cutter transmission assembly B, and the sampling cutter transmission assembly B and more than two sampling cutters form screw pairs respectively; the shell and the lead screw transmission part are coaxially installed, the rear end of the shell is open and fixed to the driving assembly B, more than two tool apron guide grooves are formed in the front end in the shell, and a sample chamber packaging head is arranged at the position, at the rear end of each tool apron guide groove, of the shell; the tool apron is coaxially sleeved on the lead screw transmission part, one end of the tool apron and the lead screw transmission part form a lead screw nut pair, the other end of the tool apron is provided with more than two sample chambers corresponding to the sampling tool, and the tool apron is coaxially sleeved on the sampling tool transmission assembly B. The sampling tool groove is arranged in the middle of the tool apron and inclines backwards.

Description

technical field [0001] The invention relates to the technical field of deep space exploration, in particular to an extraterrestrial celestial body sampling detection tool. Background technique [0002] At present, there are mainly two sampling methods for extraterrestrial celestial bodies: shallow surface sampling and deep sampling. The target object of shallow surface sampling is the loose distribution layer samples on the surface of extraterrestrial celestial bodies, while deep sampling is to collect geological samples below the surface loose layer. Compared with shallow surface sampling, in addition to obtaining deep geological samples, deep sampling can also obtain richer and more realistic scientific detection data such as regional geological fabrics, occurrence forms of special substances, and bedding distribution. The technology is difficult and the requirements for the detector platform are high. [0003] The natural pores of extraterrestrial celestial bodies are l...
