Spiral Screw Bucket Drum · 模型 255810
Construction: This design for the bucket drum is inspired by the Archimedes screw. I have tried to keep the construction as simple as possible by incorporating just a few parts. Each drum consists of two identical “compartments” which are attached 180 degrees to each other. A compartment consists of 3 main parts which are: • The Outer drum • The Archimedean spiral screw which is the most important part of this design. • The Scoop The outer drum has a rectangular hole closer to one edge, and the scoop is attached here. The axle of the spiral screw is then connected to the inner circular face of the outer drum. The spiral screw is completely hollow with a thickness of 1mm, in order to minimize weight. The best way to manufacture these parts is through sheet metal operations. All these parts can be put together using rivets and finally, the two compartments can be attached, thus completing the construction of the drum. Working: The bucket drum works in a similar way to the Archimedes screw transporting water. During loading, the regolith scooped up moves away from the opening of the outer drum due to the action of the spiral screw. There is also little chance for the regolith to escape out of the scoop while the rover moves to the dump location. During unloading, the exact opposite happens. The regolith moves towards the opening of the outer drum and ultimately exits the scoop. Specifications: Maximum bucket drum length: 360mm Maximum bucket drum diameter: 450mm Maximum bucket drum mass: 4.90-4.98 kg (assuming the material to be an Aluminium-Magnesium alloy having a density of 1.90-1.93 g/cc) Maximum total width of scoops engaged at any given time: 93mm per drum Thickness of outer drum and scoop: 1.5mm Thickness of all other components within the outer drum: 1mm Total internal volume of the bucket drum: 49.084 litres Estimated fill factor: 80-85% Maximum amount of regolith captured: 39.268-41.722 litres per drum
