Anti-blocking rice screening equipment

The invention relates to anti-blocking rice screening equipment which comprises a screening box, a pressing plate, a fixed plate, a filter screen, a rotating mechanism and a cleaning mechanism. The rotating mechanism comprises a motor, a rotary shaft, a first bevel gear, a second bevel gear, a first rolling rod, a limiting rod, fan blades, a fixed block and a pushing and shoveling assembly. The cleaning mechanism comprises a transmission assembly and a cleaning assembly. According to the anti-blocking rice screening equipment, a pressing block can be driven by the motor to push and shovel rice, and the rice is rotated to a high altitude to fall off, so that the rice shakes severely, so that impurities attached to the rice become loose and are more easily blown to the filter screen by the fan blades, and therefore, clean rice is remained. Meanwhile, the motor further can drive the slide bar to ascend and descend, so that a brush head brushes the filter screen, and therefore, the filterscreen is prevented from
