The invention provides a Mars rock soil quantitative sampling packaging device, a drill rod and a sampling vehicle, and belongs to the field of external celestial body sampling. The problems that an existing sampling device is complex in sampling packaging structure and cannot collect deep samples are solved. A Mars rock soil quantitative sampling packaging device comprises a sampling driving unit, a drilling sampling unit, a packaging unit, a bidirectional lead screw, a center drill bit and an outer drill bit, the outer drill bit is of a hollow structure, the sampling driving unit is arranged at the inner top of the outer drill bit, and the lower end of the center drill bit extends out of an opening in the lower end of the outer drill bit in a non-working state; before sampling, the two-way lead screw rotates, the packaging unit moves downwards, the center drill bit moves upwards, so that the lower end of the center drill bit and the inner wall of the outer drill bit define a cavity for containing samples, the two-way lead screw stops rotating during sampling, the two-way lead screw continues rotating after sampling, and the packaging unit moves downwards to seal an opening in the lower end of the cavity. The device is mainly used for sampling.
本发明提出了一种火星岩石土壤定量采样封装器、钻杆及采样车,属于外天体采样领域。解决现有采样设备采样封装结构复杂以及无法采集深层样品的问题。一种火星岩石土壤定量采样封装器,包括采样驱动单元、钻进采样单元、封装单元、双向丝杠、中心钻头和外钻头,外钻头为中空结构,采样驱动单元设置在外钻头内顶部,中心钻头的下端在非工作状态下从外钻头下端开口伸出;取样前双向丝杠转动,封装单元向下运动,中心钻头向上运动使中心钻头下端与外钻头内壁围合形成容置样品的腔体,取样时双向丝杠停止转动,取样后双向丝杠继续转动,封装单元向下运动将腔体下端开口封闭。它主要用于采样。
