RASSOR Bucket Drum

In this ingenious mechanism, numerous small containers are strategically placed on the lateral surface of a cylindrical body. By rotating the cylinder around its central axis, these containers are efficiently filled with soil at the lowest point and quickly begin to unload into the reservoir at the highest point. The reservoir is cleverly designed as two concentric shells stacked atop each other. When loading is completed, the outer shell rotates 180 degrees around the main axis, effectively sealing the soil inside when in motion. Conversely, during emptying, the inner shell begins to rotate and rapidly empties the soil. The volumetric capacity of a single container is precisely 0.11 liters, and sixteen are situated on the circumference. At a rotational speed of 20 rpm, this mechanism can fill its 25-liter capacity within an astonishing 45 seconds and completely empty it in approximately 3 seconds. If the entire structure is crafted from titanium, the total mass will be remarkably low at just 2840 grams. The volume capacity of the soil reservoir is approximately 25 liters and can even accommodate more. Advantages abound with this innovative design: I. Without the need for narrow ducts or grooves, there is no risk of clogging. II. Since the soil reservoir remains stationary and doesn't require rotation, less force is needed, resulting in significant energy savings. III. The mechanism boasts an impressive volume-to-mass ratio, coupled with rapid loading and unloading times. IV. As the containers are symmetrically arranged in a row, they do not generate any lateral forces.
