This 10mm drive structure is drillable into soil layers via a single motor. The design effectively utilizes material sorting and storage spaces, allowing for simultaneous integration during collection. It boasts robustness, simplicity, ease of control, compactness, and modular functionality. The gravel layer consists of reciprocating relative movements between the collecting bucket and integral filter plate, with gravel collected via the upper end's large hole, then stored through a chute (<10mm, >dust). The dust layer captures dust and lunar soil via the same relative movement, stored in the lower end hole and upper second-layer filter, then channeled through the chute. In the rock layer, rocks larger than 20mm unfilterable after bucket's reciprocating motion are held within a storage space formed by a shutter switch structure closure. A camera shutter structure rotates, meshing with upper and lower moving collecting barrels; its lower end sports a short thread initiating open upon rotation, closing once recovered. Spiral-distributed arrays feature one-way film passage - when in collection state, films deform to admit objects into the cavity, distributing helically during collection for increased force while maintaining unidirectionality to prevent backfall.
