[0044] Working principle:

[0045] After the sorting is completed, the smallest particle bauxite is leaked from the bottom of the sorting frame 11, and falls into the inside of the collecting frame 31; then, through the external controller, the controller drives the electric push rod 33 to extend and retract, and the electric push rod 33 extends and retracts synchronously to drive the push plate 34 to move, so that the push plate 34 moves in the collecting frame 31 and pushes the bauxite out.

[0046] This step avoids the accumulation of bauxite at the bottom, and facilitates the collection of the bauxite.
