[0022] Please see Figure 1-4 This utility model provides an embodiment of a dust-proof iron tailings sand particle screening device, including a base 1 and a fixed box 2. The fixed box 2 is fixedly connected to the top of the base 1. A collection box 3 is provided inside the fixed box 2. A handle 4 is fixedly connected to the front end of the collection box 3. Side plates 6 are fixedly connected to both sides of the top of the base 1. A fixed frame 15 is fixedly connected between the top ends of the side plates 6. Fixed blocks 16 are fixedly connected to both sides of the front end of the fixed frame 15. A dust cover 17 is movably hinged to the rear end of the top of the fixed frame 15. A feed inlet 18 is provided at the rear end of the dust cover 17. A positioning buckle 19 is movably hinged to the top end of the dust cover 17.
[0023] The positioning buckle 19 matches the position of the fixing block 16, and the dust cover 17 is made of transparent material;
[0024] Specifically, such as Figure 1 and Figure 4 As shown, the dust cover 17 is flipped down and fastened to the outside of the fixing block 16 using the positioning buckle 19. The ore and gravel can be put into the screen frame 20 through the feed port 18 of the dust cover 17, so that dust is not easily scattered during screening.
[0025] A drive motor 7 is fixedly installed on the outside of the side plate 6. A turntable 8 is fixedly connected to the output end of the drive motor 7. A linkage block 9 is movably connected to the top of one side of the turntable 8. A first connecting seat 5 is fixedly connected to one side of the fixed box 2. A fixed shaft 11 is longitudinally arranged inside the first connecting seat 5. A bracket 12 is fixedly connected to the top of the fixed shaft 11. A second connecting seat 10 is sleeved and fixed to the outside of the fixed shaft 11.
[0026] The first connecting seat 5 is provided in two sets, with two in each set, and the first connecting seat 5 is symmetrically distributed on both sides of the fixed box 2;
[0027] The fixed shaft 11 is movable inside the first connecting seat 5, and the bottom end of one side of the linkage block 9 is movably connected to one side of the second connecting seat 10.
[0028] Specifically, such as Figure 1 and Figure 3 As shown, when the drive motor 7 is turned on, the turntable 8 is driven to rotate, which can drive the linkage block 9 at the front end to move. When the linkage block 9 moves, it can drive the second connecting seat 10 on one side to move up and down. At this time, the fixed shaft 11 will move up and down repeatedly inside the first connecting seat 5, thereby realizing the vibration of the screen frame 20.

At this time, the screen frame 20 can be removed from the bracket 12, making it convenient to replace the new screen frame 20.
[0031] Working principle: When using this utility model, firstly, the dust cover 17 is flipped down and fastened to the outside of the fixing block 16 using the positioning buckle 19. The ore and gravel can be put into the screen frame 20 through the feed port 18 of the dust cover 17, so that dust is not easily scattered during screening. Then, the drive motor 7 is turned on to drive the turntable 8 to rotate, which can drive the front linkage block 9 to move. When the linkage block 9 moves, it can drive the second connecting seat 10 on one side to move up and down. At this time, the fixed shaft 11 will move up and down back and forth inside the first connecting seat 5, thereby realizing the vibration of the screen frame 20. The gravel can fall into the collection box 3, making the screening more stable and applicable. Finally, when the screen frame 20 needs to be replaced, the positioning bolt 14 can be unscrewed to separate it from the connecting block 13. At this time, the screen frame 20 can be disassembled from the bracket 12 for easy replacement with a new screen frame 20.
