Fresh leaf sorting machine

The invention discloses a fresh leaf sorting machine which comprises a machine frame, a belt transmission mechanism, a screen drum and a screen net cleaning mechanism; a rotating shaft is horizontally erected on the machine frame; and the screen drum is in sleeve connection with the rotating shaft in a coaxial interval manner, a feeding opening and a discharging opening are respectively formed in the two ends of the screen drum, and a plurality of classified screening sections are separately arranged on the screen drum. The belt transmission mechanism comprises a motor, a speed changing box, a driving wheel, a driven wheel and a transmitting belt; the driving wheel is coaxially arranged on an output shaft of the speed changing box, and the driven wheel is coaxially and fixedly connected to one end of the discharging opening of the screen drum; a leaf cleaning broom is fixedly connected with the rotating shaft; a double-rocker mechanism is arranged between the output shaft of the speed changing box and the rotating shaft; and the leaf cleaning broom can be driven by the double-rocker mechanism to swing in the screen drum along with the rotating shaft. Due to the fact that the double-rocker mechanism can drive the leaf cleaning broom to swing in the screen drum along with the rotating shaft, the screen net plug removing operation can be easily achieved. The double-rocker mechanism is of a mechanical transmission structure, good in reliability, stable in operation and suitable for long-time continuous production.
