RASSOR CONTAINER DESIGN · 模型 267811
In this proposed concept we have three major parts, which are 1. Loading Shovel Mechanism 2. Static Regolith Collection Drum (Fixed Drum) 3.Unloading Lid Mechanism with Screw Extruder. For loading operation, the lid vent is positioned on topside by rotating it on counter clockwise direction. Then the shovel assembly starts running on counter clockwise direction to load the regolith to the collector drum. Once the container filled with regolith, the shovel is stopped and the lid is rotated 180 degree on clockwise direction and the lid vent positioned to bottom side of the drum. Then the regolith will be unloaded by screw extruder. Dimensions: Bucket Length : 356 mm Bucket Diameter : 445mm Scoop Width : 85 mm No. of. Scoops : 3 No’s Container Length : 297 mm Container Diameter : 370mm 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: Since we are using additional screw extruder unloading mechanism, the unloading mechanism is not gravitational force depended. For unloading the entire bucket/container is not rotated, the output Lid alone rotated to unload the regolith. More than 90% fill ratio can be achieved. Maximum Fill ratio achieved. Simple mechanism with few movable parts, and less parts count. While unloading process, the entire container is not rotated, so minimum force is required to unload the regolith. It reduces the power consumption of motor, also reduces the motor power/torque requirements. The container can be completely unloaded by the screw extruder. Steps of Operations: Clockwise: When motor rotating on clockwise the Lid rotates with shovel on clockwise direction till the output vent positioned on topside of the drum. Then the lid rotation stopped by 180 degree stopper. The shovel continuously rotates and loads the drum with regolith. The screw extruder is locked by the ratchet freewheel lock and it is not rotated along with shovel. Counter Clockwise: When motor rotating on counter clockwise, the Lid is rotated with screw extruder on counter clockwise till the output vent positioned 180 degree downside. Then the lid is locked by the stopper. Still the screw extruder is running for unloading the regolith. The shovel assembly is locked by the ratchet freewheel mechanism an...
