The anti-blocking winnowing machine feeding structure comprises a feeding hopper, a feeding frame, an upper vibration table and a lower vibration table, the feeding frame is arranged below the feeding hopper, the feeding hopper is of a hollow circular truncated cone structure, the feeding hopper and the feeding frame are of an integrated structure, the upper vibration table is arranged on the outer side of the feeding frame, and the lower vibration table is arranged on the lower side of the feeding frame. The upper vibration table is of a hollow frame-shaped structure, and upper vibration table hooks are arranged at the four corners of the lower surface of the upper vibration table. A CPB laser sensor is installed in a sensor installation hole in the side face of the feeding hopper, so that under the condition that the feeding speed is too high, an operator can find out the blocking situation in the feeding hopper in time, and the feeding hopper is prevented from being blocked by the CPB laser sensor.
