[0002] A vibrating screening device is a mechanical device commonly used for screening and grading granular materials. It separates granular materials into particles of different sizes through vibration motion. This device is usually composed of a vibrating motor, a screen, a screen frame and a supporting structure. Publication No. CN217222356U discloses a vibrating screening device, including a screening box, a vibrating motor is fixedly connected to the bottom of the screening box, a plurality of fixed columns are fixedly connected to the bottom of the screening box, a first spring is fixedly connected to the bottom of the plurality of first springs, a bottom of the bottom of the bottom plate is fixedly connected to a plurality of support columns, and the mounting mechanism includes a sliding mechanism with an inner cavity of the screening box. The sieve plate is movably connected, and sliders are fixedly connected on the left and right sides of the sieve plate. The front of the bottom of the sieve plate is fixedly connected to the box. By providing a mounting mechanism inside the screening box, the mounting mechanism can install and disassemble the screen, which is convenient for cleaning and replacing the screen. However, this type of vibrating screening device does not have a crushing function.

The movable top plate 4 is slidably connected to the chute 3. The vibration motor 6 is symmetrically fixedly installed on the lower surface of the screening plate 5. A first fixed plate 8 and a second fixed plate 9 are fixedly installed on the top of the box body 1 respectively. A driving motor 10 is fixedly installed on the surface of the first fixed plate 8. A threaded rod 12 is fixedly installed on the output end of the driving motor 10. Side plates 13 are symmetrically fixedly installed on the top of the box body 1. A limiting groove 14 is provided on the inner side of the side plate 13, a connecting block 15 is provided on the surface of the threaded rod 12, and a limiting hole 16 is provided on the surface of the connecting block 15. Connecting plates 17 are symmetrically fixedly installed on both sides of the connecting block 15, and a limiting block 18 is fixedly installed on the outer side of the connecting plate 17. A fixing rod 19 is fixedly installed on the inner side of the connecting plate 17, and a crushing roller 20 is rotatably connected to the outer side of the fixing rod 19. The inner support frame 2 supports the movable top plate 4, and the crushing roller 20 moves and rotates above the movable top plate 4, so as to perform preliminary crushing processing on large or agglomerated materials.

[0025] See also Figure 1-4 A support plate 11 is fixedly installed on one side of the box body 1, and the support plate 11 is located below the drive motor 10. The support plate 11 supports and fixes the drive motor 10. The threaded rod 12 is arranged through the limit hole 16. The crushing roller 20 is located above the movable top plate 4. The crushing roller 20 is used to perform preliminary crushing of large or agglomerated materials, avoiding direct vibration screening of large materials. The limit block 18 is slidably connected to the limit groove 14. The limit block 18 has a rounded corner. The rounded corner setting is conducive to the rapid sliding of the limit block 18 in the limit groove 14. A soft pad 21 is fixedly connected to the surface of the limit block 18. The soft pad 21 is made of rubber. The rubber material has a certain elasticity, which improves the buffering effect of the soft pad 21 and avoids the limit block 18 directly colliding with the inner wall of the limit groove 14 to cause wear.

[0026] Example 2

[0027] See also Figure 5 One side of the box body 1 is symmetrically connected to a rotating rod 23, and a rotating block 24 is fixedly installed on the surface of the rotating rod 23. The rotating rod 23 is used to facilitate the rotation of the rotating block 24 on one side of the box body 1.

An auxiliary handle 22 is fixedly installed on one side of the movable top plate 4, and an auxiliary protruding rod 25 is fixedly installed on the surface of the rotating block 24. The auxiliary handle 22 helps in the push-pull operation of the movable top plate 4, and the auxiliary protruding rod 25 helps to rotate the rotating block 24.

[0028] Working principle: The staff starts the driving motor 10, and then the driving motor 10 drives the threaded rod 12 to rotate, so that the connecting block 15 can move under the joint action of the threaded rod 12 and the limit block 18. Then the connecting block 15 drives the connecting plate 17 to slide back and forth above the movable top plate 4. At this time, the limit block 18 slides in the limit groove 14, so that the crushing roller 20 moves above the movable top plate 4 and rotates at the same time, so that the crushing roller 20 is used to preliminarily crush large or agglomerated materials, avoiding direct vibration screening of large materials. When the material is crushed, it is prevented from causing wear and damage to the vibration screening device, thereby increasing the service life of the equipment. After the first round of crushing is completed, the staff will rotate the rotating block 24 to a horizontal angle, and then use the auxiliary handle 22 to pull the movable top plate 4 outward, and then the movable top plate 4 will slide in the chute 3, so that the material after the preliminary crushing can enter the box body 1, and the vibration motor is used to drive the screening plate 5 to vibrate, thereby vibrating and screening the material, and finally the material flows out from the discharge barrel 7. Similarly, the second and third rounds of crushing can be carried out in the same way.
