Embodiment Construction

[0022] Such as Figure 1 to Figure 5 As shown, the lunar soil sampler coring actuator of the present invention mainly includes: electromagnet 1, fixed plate 2, heavy hammer gland 3, textile material rope 4, chute column 5, spring 6, heavy hammer 7, claw Reed shaft 8, lock nut 9, fixed body 10, drilling tool 11, limit reed 12, pull out pin 13, claw spring basket 14, claw spring 15, slideway body 16, resistance wire 17 and pull out pin seat 18. According to the function, it can be divided into four parts: drilling and coring mechanism, sample sealing mechanism, unlocking mechanism and separation mechanism.

[0023] Such as figure 1 As shown, the drilling and coring mechanism is located at the front end of the entire device, and is used to realize the drilling of lunar soil and the collection of samples. The drilling and core-taking mechanism of the present invention comprises a drilling tool 11 , a claw spring shaft 8 , a lock nut 9 , a chute post 5 and an electromagnet 1 . T...

Abstract

The invention discloses a coring execution device for a lunar soil sampler, which includes a drilling and coring mechanism, a sample sealing mechanism, an unlocking mechanism and a separation mechanism; wherein, the drilling tool for drilling into the coring mechanism is an outer spiral and an inner hollow structure; the sample sealing mechanism The unique design of claw spring, claw spring flower basket and slideway body is adopted; the unlocking mechanism adopts the design of fixed body, limit spring, extraction pin and extraction pin seat, and the unlocking action of the drilling tool can be realized by pressing the extraction pin; The separation mechanism can trigger a large impact energy with a small heating power of the resistance wire to complete the entire separation action. The whole device has a simple structure, and can reliably realize the functions of collecting and sealing lunar surface samples, unlocking and separating drilling tools, and the like.

Description

technical field [0001] The invention belongs to the technical field of spacecraft deep space exploration, and in particular relates to a lunar soil sampler coring execution device suitable for lunar surface environment application. Background technique [0002] In deep space exploration activities, after a soft landing on the surface of a star, it is an important task and key technology in deep space exploration to detect and sample the surface of a star and return the obtained valuable samples to Earth. [0003] At present, there are still many technical difficulties that need to be overcome in this technology. For example, due to the interlocking of lunar soil particles, it is difficult to slide each other, so that the lunar soil is almost similar to solid rock in terms of resistance to foreign object wedging, and it is not easy to drill; the thermal conductivity of lunar soil is extremely low, resulting in A large amount of heat is not easy to discharge, and it is easy t...
