Sweeper v1

Sorry about awful presentation. Main idea is drums should load quickly and unload quickly on low gravity conditions.Nothing special about drums, except inside diameter is constant, scoops attached outside the drums without changing inner diameter.Inside the drums, there are sweepers which turning apart from buckets and works as a brush/scraper to quickly takes whatever comes from scoops. Sweepers rotates 20% faster than the drums. As seen the figures; sweepers can deploy soil pieces almost without gravity. There are problems though, rotations of both drum and sweepers will cause some buckling problems. And it will added to original Rassors torsion problem.Tougher ragolith pieces will squeze/jam between sweepers and drum, to bypass that, sweeper's outer ends may change with kind of metal brush. And it will prevent future problems like minor ragolith pieces getting between drums and sweepers causing bent sweepers or, scratching drums.Problem with the necessity of operators constant input is still continuous. Drums designed as 3 slices, each of them 120mm length and 450 mm diameter. Each slice has 3 scoops which equally apart from each other.Total diameter 450mmScoop width 120mmTotal length 360mmVolume: approx 38,5 LAgain sorry about presentation.
