[0024] In this embodiment, a vibration machine is installed inside the vibration box 1, and the first screening plate 6 and the second screening plate 8 are both arranged at an angle. The aperture of the second screening plate 8 is larger than the aperture of the first screening plate 6. The large particles of gravel in the sand and gravel are screened through the second screening plate 8 and discharged through the second discharge port 9. They are further screened through the first screening plate 6 and discharged through the first discharge port 7. The qualified sand is discharged through the inclined plate 5 for easy screening.

[0025] In this embodiment, the plug post 12 is snap-fitted to the limiting groove 10 , and the fixing member 11 is located outside the limiting groove 10 and is threadedly slidable. The fixing member 11 is rotated to fix the fixing member 11 , which facilitates the installation and disassembly of each screening box 4 .

[0026] In this embodiment, the dust-proof mechanism 3 includes a cover plate 14, which is installed on the top of the screening box 4. A feed port 15 is opened through the top of the cover plate 14, and a baffle 16 is installed on the inner side of the bottom of the cover plate 14. The front and rear end outer walls of the feed port 15 are both installed with a force tube 17. A dust-proof plate 18 is movably installed inside the feed port 15. A hinge 19 is installed at one end of the dust-proof plate 18 and connected to the inner wall of the feed port 15. A shaft rod 20 is installed through both ends of the hinge 19 and inside the force tube 17. A spring 21 is installed on the periphery of the shaft rod 20. Sand and gravel enter through the feed port 15, and the dust-proof plate 18 rotates, tilts and opens.

[0029] It should be noted that the utility model is a vibrating screen for construction. When in use, first turn on the power and start the vibrating machine in the vibration box 1, and at the same time pour the sand and gravel used for construction from the feed port 15. The sand and gravel rotate and open the dustproof plate 18 under the action of gravity and fall on the baffle 16. When the sand and gravel leave the dustproof plate 18, the spring 21 drives the shaft 20 to restore the dustproof plate 18 to close for dust prevention. When screening, the sand and gravel slide from the baffle 16 to the second screening plate 8, and the vibration box 1 The vibrating machine inside drives the three screening boxes 4 to vibrate, and the second screening plate 8 screens the large particles of gravel in the sand and gravel, and discharges them through the second discharge port 9. The screened sand and gravel fall onto the first screening plate 6, screens the small particles of gravel, and discharges them through the first discharge port 7. The qualified sand screened out falls onto the inclined plate 5 and is discharged. When it is necessary to disassemble, clean or replace a different screening plate, rotate the corresponding fixing part 11 to disengage the screw of the fixing part 11 from the plug 12, and take out the top screening box 4 for cleaning or replacement.
