RASSOR CONTAINER DESIGN

In this proposed concept, we have three major parts: 1. Loading Shovel Mechanism, 2. Static Regolith Collection Drum (Fixed Drum), and 3. Unloading Lid Mechanism with Screw Extruder. For loading operation, the lid vent is positioned on top by rotating it in a counter-clockwise direction. Then, the shovel assembly starts running in a counter-clockwise direction to load regolith into the collector drum. Once the container is filled with regolith, the shovel stops and the lid rotates 180 degrees in a clockwise direction, positioning the lid vent at the bottom of the drum. Next, the regolith is unloaded by the screw extruder. Dimensions: Bucket Length: 356 mm Bucket Diameter: 445 mm Scoop Width: 85 mm Number of Scoops: 3 Container Length: 297 mm Container Diameter: 370 mm Physical Properties: Fill Volume: 28.7 Liters Fill Ratio: 92% Bucket Body Mass: 3.897 Kg (bucket + shovel + lid) Material Used: Carbon Fiber, Titanium Advantages: Using an additional screw extruder unloading mechanism allows for a non-gravitational force dependent unloading process. During unloading, the entire bucket/container is not rotated; instead, only the output lid rotates to unload regolith. More than 90% fill ratio can be achieved, resulting in maximum fill efficiency. The simple mechanism features few movable parts and a low part count. While unloading, the entire container remains stationary, minimizing the force required to unload regolith and reducing power consumption. Steps of Operations: Clockwise: When rotating clockwise, the lid rotates with the shovel in a clockwise direction until the output vent is positioned at the top of the drum. The lid then stops at 180 degrees using a stopper. Meanwhile, the shovel continues to rotate, loading the drum with regolith. The screw extruder is locked by a ratchet freewheel lock and remains stationary. Counter-Clockwise: When rotating counter-clockwise, the lid rotates with the screw extruder in a counter-clockwise direction until the output vent is positioned 180 degrees below. The lid is then locked using a stopper. Meanwhile, the screw extruder continues to run, unloading regolith from the container. The shovel assembly remains stationary, locked by a ratchet freewheel mechanism. https://youtu.be/AgKBdvESv2I
