Problems solved by technology

The ordinary axial energy-shaping charge structure can use the energy-gathering effect to break and open solid minerals under the condition of small doses, and has less impact on the surrounding environment and potential safety hazards, but at the same time it will cause mineral fragments to fly around, which is not conducive to follow-up Collecting and sampling work, so it is necessary to redesign the special shaped charge structure to assist in the sampling of minerals on the surface of the alien planet

Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] This embodiment provides a shaped charge structure for assisting in the sampling of extraterrestrial minerals, which can be driven by less explosive explosions in a low-gravity, vacuum-free and oxygen-free environment to form an annular jet to penetrate hard minerals, and at the same time, drive flyers Breaking up bulk minerals facilitates sampling.

[0032] Such as figure 1 As shown, the shaped charge structure includes: an initiation mechanism 1 , a casing 2 , an explosive column 3 , an annular charge cover 4 , flyers 5 and a buffer body 6 .

[0033] The connection relationship of the shaped charge structure is as follows: figure 2 As shown, the casing 2 is a stepped shaft-shaped circular tube with openings at both ends, and the explosive column 3 is coaxially filled in the inner cavity of the large end of the casing 2, so that one end of the e...

Abstract

The invention discloses an energy-gathering charge structure for assisting the sampling of extraterrestrial minerals. The two ends are opened respectively, and the explosive column is coaxially loaded in the inner cavity of the large end of the shell, so that one end of the explosive column is in contact with the inner bottom surface of the shell, and the other end is pressed and fitted with the end of the shell through the ring-shaped drug cover. And the convex surface of the annular liner is pressed against the end of the explosive column; a flyer is installed between the central end surface of the annular liner and the explosive column, and a buffer body is arranged between the flyer and the explosive column; a detonator is arranged inside the small end of the shell Mechanism for detonating explosive columns; wherein, the annular charge cover includes: an annular groove and a circular end face integrally connected to the center of the annular groove, and the cross section of the annular groove is crescent-shaped, which is connected to the circular end surface One end is the inner side, and the end connected with the shell is the outer side, so that the inner wall thickness of the annular groove is greater than the outer wall thickness.

Description

technical field [0001] The invention relates to the technical field of engineering blasting and extraterrestrial mineral sampling, in particular to an energy-gathering charge structure for assisting extraterrestrial mineral sampling, and in particular to a method for crushing solid minerals on an extraterrestrial planet by utilizing explosive column explosion, energy-gathering, and crushing effects. A shaped charge structure for collecting effective small samples. Background technique [0002] Mineral sampling usually carried out on the surface of the earth refers to taking a certain amount of mineral samples from ore bodies, mines, etc. according to certain specifications or weight requirements, and conducting mineralogy, mineralogy and petrology on ores and rocks through analysis, testing and identification. The research is to ascertain the mineral composition and content of ore and surrounding rock, symbiotic combination, structural structure, mineral particle size and em...
