machine body, a pre-cleaning plate, a
backflow plate, a cleaning upper screen, a cleaning lower screen and a connecting rod driving
assembly; the connecting rod driving
assembly comprises: a driving eccentric shaft which is installed on the
machine body and is drivingly connected with a power device; a driving arm, a first end of the driving arm being drivingly connected with an end of the driving eccentric shaft; a
rocker arm, first and second ends of the
rocker arm being respectively hinged to the same
hinge point of the pre-cleaning plate, and a second end of the
rocker arm being hinged to the cleaning lower screen; a rocker arm supporting shaft which is fixed to the
machine body; wherein a driving
hinge point and a
fixed hinge point are sequentially arranged between the first and second ends of the rocker arm, the driving
hinge point being used for being hinged to the cleaning upper screen, and the
fixed hinge point being used for being hinged to the rocker arm supporting shaft; and the
backflow plate comprises a driving rod
assembly which is fixed to the machine body and is used for being hinged to the pre-cleaning plate. The cleaning device realizes synchronous and opposite movements of various components.
