Two handles 23 are fixedly connected to one side of the mounting plate 12, and a rectangular opening 24 is provided on one side of the two handles 23. The rectangular opening 24 is opened on one side of the dustproof box 1, and the mounting plate 12 is slidably connected to the inside of the rectangular opening 24 through the two handles 23.
[0027] During operation, after the equipment is assembled, when it is necessary to screen cement, cement can be injected into the screening barrel 5 through the injection port 2 and fall on the top of the screen 13, and then the vibration motor 9 at the bottom of the vibration seat 7 is started, and the vibration seat 7 is driven to vibrate by the operation of the vibration motor 9. The vibration efficiency of the vibration seat 7 can be improved by using multiple reset springs 10, and the screening effect of cement can be improved. The bracket 8 can be used to improve the stability of the vibration seat 7 to prevent the vibration seat 7 from collapsing or dislocating during the vibration process. And by using the connection between the screening barrel 5 and the vibration seat 7, the screening barrel 5 vibrates synchronously, and then the cement screening work is started, so that qualified cement can stably pass through the screen 13 and fall on the surface of the inclined plate 11, and slide through the inclined plate 11 into the bottom discharge pipe 6 and be discharged from the second discharge port 4.

When the screen 13 needs to be replaced, the mounting plate 12 can be moved by dragging the two handles 23, and the mounting plate 12 can be driven to slide inside the rectangular opening 24, and the mounting plate 12 can be removed from the middle of the screening barrel 5. Then the old one is removed, and the new screen 13 is replaced, and the mounting plate 12 is reinserted into the middle of the screening barrel 5. The mounting plate 12 can be quickly installed by using the engagement of the inner walls of the positioning blocks 15 on both sides with the outer walls of the clamping blocks 16 on both sides of the mounting plate 12. And after the mounting plate 12 is fully inserted between the two positioning blocks 15 and engaged with the inner wall of the screening barrel 5. Turn the rocker 17, and use the rocker 17 to drive the gear 18 to rotate inside the slide 19, which can drive the two rectangular plug rods 22 to slide inside the slide 19.
