The invention provides a primary packaging device for surface sampling of a small celestial body. The device comprises a driving assembly, an upper shell, a lower shell, a container cavity and a packaging assembly, the upper shell is connected to the container cavity through the lower shell, and the driving assembly is fixedly mounted to a driving mounting plate; the packaging assembly is arrangedin the container cavity and comprises a first driven gear assembly and a second driven gear assembly, a first driven gear body of the first driven gear assembly is meshed with a first driving gear ofthe driving assembly, and a second driven gear body of the second driven gear assembly is meshed with a second driving gear of the driving assembly; the inner ring of the first driven gear body is fixedly connected with the first step of the lower shell; the inner ring of the second driven gear body is fixedly connected with the container cavity; and a top cover is arranged at the top of the container cavity. According to the invention, three states of sample collection, packaging and transfer are realized by virtue of motor driving, the power consumption is reduced by utilizing fewer power sources, and the sample is reliably transferred into a return cabin.
本发明提供了一种用于小天体表面采样的初级封装装置,包括驱动组件、上壳体、下壳体、容器腔体和封装组件,上壳体通过下壳体连接至容器腔体,驱动组件固定安装至驱动安装板;封装组件设置在容器腔体内,封装组件包括一号从动齿轮组件和二号从动齿轮组件,一号从动齿轮组件的一号从动齿轮本体与驱动组件的一号主动齿轮啮合,二号从动齿轮组件的二号从动齿轮本体与驱动组件的二号主动齿轮啮合;一号从动齿轮本体的内圈与下壳体的第一台阶固定连接;二号从动齿轮本体的内圈与容器腔体固定连接;容器腔体顶部设有顶盖。本发明依靠电机驱动实现样品收集、封装、转移三种状态,利用较少动力源,降低了功耗,可靠的将样品转入返回舱内。
