The invention provides a small celestial body star soil collector and a collection method thereof, and relates to the technical field of spaceflight. The small celestial body star soil collector comprises a base and a plurality of groups of spring clusters, the spring clusters are fixed to the base at intervals, each spring cluster is conical, each spring cluster comprises a plurality of springs, the springs are obliquely arranged relative to the base, the ends, close to the base, of the spring clusters are fixed ends, and the ends, away from the base, of the spring clusters are free ends. The spring is a shape memory alloy spring and comprises a plurality of spiral rings, and micron-sized pits are formed in the surfaces of the spiral rings. In the process of applying tensile force to the small celestial body star soil collector, the micron-sized pits of the small celestial body star soil collector collect first-stage samples, the second-stage samples are collected between the adjacent coils, and the third-stage samples are collected between the adjacent springs of each group of spring clusters, so that the small celestial body star soil collector has the advantages of simple structure, convenience in operation and the like. The occupied space is small, the weight is light, and the energy consumption is low.
本发明提供一种小天体星壤采集器及其采集方法,涉及航天技术领域。小天体星壤采集器,包括底座和多组弹簧簇;多组弹簧簇间隔固定在底座上,每组弹簧簇呈圆锥形设置,弹簧簇包括多根弹簧,多根弹簧与底座倾斜设置,弹簧簇靠近底座的一端为固定端,弹簧簇远离底座的一端为自由端;弹簧为形状记忆合金弹簧,弹簧包括多个螺圈,多个螺圈的表面设置有微米级凹坑。通过在对小天体星壤采集器施加拉力过程中,小天体星壤采集器的微米级凹坑采集第一级样品,相邻螺圈之间采集第二级样品,每组弹簧簇的相邻弹簧之间采集第三级样品,小天体星壤采集器具有结构简单,占用空间较小、质量轻以及耗能低的优点。
