Abstract

The invention relates to a rapid sealing assembly with drawstring buckling for a star soil coring soft bag, and belongs to the field of star catalogue drilling and sampling mechanisms. The rapid sealing assembly with drawstring buckling for the star soil coring soft bag solves the problem that when sampling operation is carried out on an existing moon exploration project, a sealing journey of a sampling soft bag in the sealing process is long and affects the star soil collection quantity. A second sealing opening is located between a first sealing opening and an opening end of the coring softbag, wherein the first sealing opening comprises a first inhaul cable and a second inhaul cable, the two inhaul cables are used as wraps and symmetrically weaved on the coring soft bag, and the two ends of each inhaul cable are used as extending segments extending out of the coring soft bag. One extending segment of the second inhaul cable is wrapped with one extending segment of the first inhaulcable and buckling is performed, and the other extending segment of the first inhaul cable is wrapped with the other extending segment of the second inhaul cable and buckling is performed. First fracturing areas are arranged on the inhaul cables, the end part of the other extending segment of the first inhaul cable and the end part of the extending segment of the second inhaul cable are fixedly connected with limiting rings, and the first sealing opening and the second sealing opening have same structures.

Description

technical field [0001] The invention relates to a fast sealing assembly for a star soil coring soft bag with a drawstring fastening buckle, and belongs to the field of star surface drilling and sampling mechanisms. Background technique [0002] The unmanned lunar exploration project is an important milestone in the history of China's aerospace development. An important part of the lunar exploration project is the sampling work. Because the moon has the characteristics of large temperature changes and uncertain soil structure, how to do it in the mysterious environment of the moon? The task of unmanned drilling, collecting and packaging samples is particularly difficult; for the sampling and detection of lunar soil surface and deep material, drilling and sampling are mainly used as the main operation mode. The current drilling and coring mechanism is mainly composed of drilling unit and coring Due to the randomness of lunar soil particles, some characteristic particles are st...
