Design of a Multi-pipe Driller for Deep Lunar Soil Sampling

According to the condition that people only know about the lunar soil between the depths 0 and 3 meters and the existing drillers can't collect the deeper lunar soil, a new lunar soil driller that can collect the lunar soil between the depths 0 and 5 meters is to be presented in this paper. The driller needs the accommodation of great power and the help of astronauts. And it realizes the goals of deep lunar soil sampling by the interconnection and the coinstantaneous contra-rotation of the inside drill pipes and the outside drill pipes. The driller is consist of a lunar soil drilling mechanism, a mechanism recovering samples , a mechanism fixing drill pipes, a mechanism interchanging drill pipes and some drill tools. After the interconnection of 5 groups of drill pipes, the target of deep soil sampling can be realized. What's more, the samples collected by the driller can keep the sequence information. The driller has the advantages of small structure and it can collect much more lunar soil. So this kind of driller can give some technical supports to the study of deep lunar soil sampling.
