[0033] It should be noted that this utility model is a vibrating screening device for separating sludge and earthworm castings. In use, the mixture of sludge and earthworm castings is introduced into the second vibrating screen frame 5. The water storage plate 705 and the spray bar 706 in the material guiding assembly 7 begin to operate. The water stored in the water storage plate is sprayed out through the outlet on the spray bar, flushing the material inside the second vibrating screen frame 5. This helps to wash off the material adhering to the screen and promotes the separation of sludge and earthworm castings. The fixed seat 702 in the material guiding assembly 7 drives the second rotating shaft 703 to rotate, and the second rotating shaft 703 drives the material guiding frame 704 to rotate, directing the material after screening in the second vibrating screen frame 5 towards the receiving chamber 8 and through the screening port into the first vibrating screen frame 4. The vibrating motor 3 drives the vibrating frame 2 and the first and second vibrating screen frames 4 and 5 on it to vibrate. The screen on the screen frame performs preliminary screening, separating larger impurities from smaller sludge and earthworm castings. The screening and cleaning component 6 then starts working, with the drive seat 603 driving the first rotating shaft 604 to rotate. The first rotating shaft 604 drives the screening frame 605 and its screening plate 606 to rotate. The elasticity and rotational movement of the elastic screening rod 607 help prevent the screening port 9 from clogging and clean the material adhering to it during the screening process. The cleaning block 610 on the L-shaped guide frame 609 scrapes and cleans the sludge and earthworm castings adhering to the inner wall of the screening port 9 during rotation, preventing clogging. After fine screening and cleaning by the first vibrating screen frame 4 and the second vibrating screen frame 5, the sludge and earthworm castings are finally separated. The screened material falls into the receiving chamber 8 set at one end of the first vibrating screen frame 4 and the second vibrating screen frame 5 for collection.
