Problems solved by technology

[0003] Sampling techniques commonly used on the moon and Mars include drilling, mechanical arm shoveling, grinding and grabbing, etc., but the sampling reaction force is large and the sampling time is long. The Japanese Hayabusa sampled the Itokawa asteroid in 2005 , using the method of containment and recovery after the projectile hits, but the sampling amount is extremely small

Embodiment 1

[0031] A gas excitation sampler suitable for celestial bodies, including a drilling rig 1, a rock breaking tool 2, a sample container 3, a gas source 4, a gas path 5, and a brush 36; Figure 1 to Figure 5 shown.

[0032] The sample container 3 includes an inner cavity 31, an outer cylinder 32, and an upper cover 33; both ends of the inner cavity 31 are connected, the inner cavity 31 is set in the outer cylinder 32, and the upper cover 33 is installed on the outer cylinder 32; An annular cavity is formed between the inner cavity 31 and the outer cylinder 32; the rock breaking tool 2 passes through the upper cover 33 and passes through the inner cavity 31 to drill into the rock; the drilling rig 1 is used to drive The rock-breaking machine 2; the side wall of the inner cavity 31 is provided with a sealing door 34;

[0033] The gas from the gas source 4 is blown into the inner cavity 31 through the gas path 5 for blowing the sample into the annular cavity through the sealing doo...

Embodiment 2

[0038] A gas excitation sampler suitable for celestial bodies, the specific technical solution is:

[0039] (1) Composite design of drilling rock breaking and chip removal collection

[0040] When the front end of the sampler touches the surface of the star, the drilling rig 1 drives the rock breaking machine 2 to start working to enhance the degree of fragmentation of the surface of the star, and then blows high-pressure gas on the surface sideways, under the action of the air flow, the surface debris is fluidized and together with the air flow Blown into sample container 3.

[0041] (2) Design of disc support for drilling into broken rock

[0042] The sample container 3 is in the shape of a disc, which provides a solid support for the sampler, especially the drilling machine 1 and the rock breaking machine tool 2, so that the drilling process is more stable and will not overturn.

[0043] (3) One-way flow channel, sample collection design on both sides of the arc

[0044]...

Abstract

The invention, which belongs to the technical field of deep space exploration, provides a gas excitation sampler for celestial bodies. The sampler comprises a drilling machine, a rock breaking machinetool, a sample container, a gas source and a gas circuit. Wherein the sample container comprises an inner cavity, an outer cylinder and an upper cover; the two ends of the inner cavity are communicated, the inner cavity is sleeved with the outer cylinder, and the upper cover is installed on the outer cylinder. An annular cavity is formed between the inner cavity and the outer cylinder; the rock breaking machine tool penetrates through the upper cover, passes through the inner cavity and then is used for drilling to break rock; the drilling machine is used for driving the rock breaking machine; a packaging airtight door is arranged on the side wall of the inner cavity; gas of the gas source is blown into the inner cavity through the gas path and used for blowing a sample into the annular cavity through the packaging airtight door.

Description

technical field [0001] The invention relates to a gas excitation sampler suitable for celestial bodies, which belongs to the technical field of deep space detection. Background technique [0002] The detection of extraterrestrial celestial bodies has significant significance for our country to "open up new frontiers, reveal the origin of life, promote technological progress, develop natural resources, and protect the safety of the earth." There are different forms of scientific detection of small celestial bodies, among which sampling is the core technical means of detection activities. The most comprehensive and direct scientific research can be carried out in the laboratory after the samples are returned to the earth. At present, the sampling of extraterrestrial celestial bodies requires the sampler to have geological characteristics adaptability Strong, low reaction force, rapid sampling and so on. [0003] Sampling techniques commonly used on the moon and Mars include d...
