Recovery device of lunar deep soil collector

Abstract

The invention discloses a recovery device of a lunar deep soil collector, which is composed of an upper and a lower frame. A recovery box driving motor is installed on the lower frame, inside which a gear train is mounted. A first level driven gear meshes with a driving gear on the shaft of the recovery box driving motor, and a last level driven gear is mounted on the recovery box driving disk onthe same shaft. A recovery box cover is disposed in a central hole of the upper frame, the four corners of which are respectively provided with a linear motor. And the movement end of each linear motor is aligned to respective clamping slots uniformly distributed on the circumferential peripheries of the recovery box cover. The recovery box is arranged between the upper and lower frames. A bolt on the lower end surface of the recovery box is inserted into a corresponding through hole on the driving disk. An external thread on the upper end of the external cylindrical surface of the recovery box cooperates with an internal thread on the internal cylindrical surface of the recovery box cover. Therefore, the device of the invention has the advantages of concise and compact structure, space saving, small recovery mass, high driving mode reliability, easy and reliable sample sealing and transfer, and can be used for lunar soil transfer, sealing and recovery after the sampling of a lunar soil multi-rod drill.

Description

technical field [0001] The invention relates to a recovery device of a soil collector, in particular to a recovery device of a lunar deep layer soil collector. Background technique [0002] Since the middle of the 20th century, humans have been exploring the moon continuously. From 1958 to 1976, the United States and the Soviet Union launched a total of 108 lunar probes, 52 of which were successful or partially successful. Lunar exploration made epoch-making achievements. The Apollo program of the United States and the Luna program of the Soviet Union carried out manned and unmanned lunar landing samples respectively, and a total of 382.0211kg of lunar samples were obtained. Among them, Apollo of the United States plans to collect about 381.7kg of lunar samples, and Luna of the Soviet Union plans to collect about 0.3211kg of lunar samples. Among them, Apollo plans to collect samples basically manually, while Luna plans to collect samples automatically. [0003] Deep dril...

Problems solved by technology

[0004] The reliability of the early Soviet alien sampling and recovery devices was not high. Luna20 only recovered 55g of samples due to leakage during the sample transfer process; most of the alien sampling devices studied in Europe and the United States recently analyzed the sampled samples on the spot without returning Earth, so the corresponding recovery device is not as developed as deep drilling

However, my country’s lunar exploration program needs to return to the moon to collect samples, and requires a large amount of samples. At present, the deep lunar soil collectors in various countries have solved the problem of collecting deep lunar soil, and the recovery device that transfers and recycles the collected lunar soil but lack of research
