[0033] In use of the vibration screen with the quick-release aperture plate structure, the vibration screen needs to be placed at the required position, and then the material can be screened by the vibration screen. In this process, the vibration motor 5 needs to work to drive the lifting plate 4 and the screen frame 6 to swing up and down. The telescopic rod 3 will extend and retract during the up and down movement of the lifting plate 4. At this time, the aperture plate 10 will move up and down with the screen frame 6 and screen the material. The material on the upper end of the aperture plate 10 will be discharged from the discharge port one 7, and the material falling from the inside of the aperture plate 10 will be discharged from the discharge port two 8 to the inside of the connecting pipe 9 and then discharged from the inside of the connecting pipe 9, thereby completing the use process of the vibration screen and effectively improving the convenience of the vibration screen.

[0034] In one embodiment, as shown in Figures 1-6 the problem of inconvenient replacement of the aperture plate 10 of the existing vibration screen is solved.

[0035] The inside of the screen frame 6 is clamped and installed with a limiting block 12, and the end of the limiting block 12 away from the screen frame 6 is slidingly installed with a fixed block 13, and the end of the limiting block 12 close to the fixed block 13 is fixedly installed with a return spring 14.
