The invention discloses an ultrasonic vibration screen convenient to maintain. The ultrasonic vibration screen convenient to maintain comprises a base; an operation panel and a power supply interfaceare mounted on the side surface of the base; an ultrasonic generator is mounted in the base; the upper surface of the base is connected with the bottom of a first cavity through a damping spring; a second cavity is formed above the first cavity; a screen net frame is arranged between the first cavity and the second cavity; a screen net and a pair of transducers are mounted on the screen net frame;a first discharge port and a second discharge port are mounted on the side surfaces of the first cavity and the second cavity; a dustproof cover is connected above the second cavity through a bundlering; a bundle ring latch is arranged on the bundle ring; and a feed port is formed in the top end of the dustproof cover. Through arrangement of the bundle ring latch, the screen net, the bundle ring, the first discharge port and the second discharge port, the ultrasonic vibration screen convenient to maintain solves the problem of complicated internal structure and difficult repair and check ina traditional ultrasonic vibration screen.
