In this embodiment, the first driving mechanism and the second driving mechanism are both servo motors, the first driving mechanism drives the two gear shafts 603 to rotate through two synchronous belts, and the second driving mechanism drives the toothed structure 501 to rotate through the driving gear. The control mechanism is an existing single-chip microcomputer. Each rotating shaft is provided with a crushing blade assembly 602 and two spiral blades 601.
