Novel rice screening machine

The invention provides a novel rice screening machine which comprises a bottom plate, movable wheels, an installation sheet, a vibration control switch, a material suction control switch, a fixed protection power wire winding frame structure, an isolation protection rice isolation box structure, a cleaning protection rice cleaning frame structure, a protection box, a protection net, a vibration motor, a feed hopper, an installation pipe, an insertion rod, an adjusting bolt and a protection hole. The movable wheels are connected to four corner positions at the bottom of the bottom plate throughbolts; the installation sheet is connected to the right side of the front surface of the bottom plate through bolts; and the vibration control switch and the material suction control switch are sequentially embedded in the middle of the front surface of the installation sheet from left to right. Due to the arrangement of a fastening plate, a protection wheel, a fixing shaft, a connecting shaft, arocker rod, a handle and a locking piece, a power wire is favorably fixed; and due to the arrangement of a fixed seat, a storage box, an isolation net, a material suction pipe, a threaded pipe and amaterial suction pump, isolation of rice is facilitated.
