NASA Regolith Intake Design · 模型 267880
This design consists of "teeth" placed in front of scoop part so it can dig up the ground and sort the large regolith pieces out(sorting size can be changed by spacing the teeth farther apart). There are 6 sections of teeth and scoops revolved around the 385mm circle. The scoops meet the max diameter at the point(seen in the 4th image) and the teeth are about 5mm from the max, this allows for maximum volume. The volume is just over 18L . Regolith can be captured and fill the entire cavity due to the panels inside. The panels inside prohibits the regolith from escaping as they would be spring loaded to the point where the reverse centripetal force could open them(allowing regolith to be removed) and the forward centripetal force would keep the regolith inside. Of course you would only be able to fill the container with a bit less regolith to allow space for the panels, but they could be shortened to fit the design to your needs. The width of a single container is 119mm, which makes the entire intake just under 360mm. The cylinders are rotated 22.5deg out of phase of each other, for better intake. The walls are 5mm thick, so a titanium body would be light and more than strong enough. This design would be best manufactured if it was 3d printed, but I believe it would still be viable to craft it without 3d printing.
