The invention discloses a vibrating screen with a multifrequency vibrator. The multifrequency vibrator is arranged between a screen of the vibrating screen and a body of a screening machine, a housing of the multifrequency vibrator is fixed on the body of the screening machine, a first rotary shaft is arranged on the side face of the housing, first elastic rubber and a first steel tube are arranged on the first rotary shaft, rubber plates are arranged in the housing, a vibrating body is arranged between the rubber plates, a vertical hitting rod, a first rotary shaft, first elastic rubber and the first steel tube are arranged in the vibrating body, the top end of the vertical hitting rod penetrates through the top of the housing and a hitting ring is fixedly arranged at the top end of the vertical hitting rod, and the distance between the hitting ring and the screening is 1-2mm. The vibrating screen disclosed by the invention is reasonable in structure and convenient to use. The two pieces of elastic rubber deform while the body of the screening machine vibrates, so that the vibrating body vibrates up and down at an irregular frequency so that the hitting ring flaps materials blocking the screen to fall off, and therefore, the screening efficiency of the vibrating screen is improved.
