The invention relates to the technical field of rice huller design, and discloses a rice huller with a variable-frequency vibration feeding function. The rice huller comprises a machine body, a feeding hopper, a falling plate, two rubber rollers, a discharge port, an extraction pipe and an air inlet, a first guide plate is arranged at the upper end in the feeding hopper, and a second guide plate is further arranged at the position, located at one side of the first guide plate, in the feeding hopper. The lower end of the first guide plate inclines towards one side of the second guide plate, a rotating shaft is arranged at the position, located at the lower end of the second guide plate, in the machine body, feeding paddles are arranged at the peripheral side of the rotating shaft, and a driving motor used for being connected with the rotating shaft is arranged at the outer side of the feeding hopper. After rice enters the feeding hopper, the driving motor is used for driving the rotating shaft and the feeding paddles to rotate, and at the moment, the feeding paddles can turn over the rice between the first guide plate and the second guide plate and apply downward acting force to the rice, so that the possibility that the rice is blocked between the first guide plate and the second guide plate can be reduced.
