[0019] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a vibrating screen mesh according to this utility model.

[0020] like Figures 1 to 4 As shown, this utility model discloses a vibrating screen mesh, including a screen 1 and a protective net 2 disposed on one side above the screen 1, with the protective net 2 connected to the screen 1 via a connecting assembly. Specifically, the protective net 2 is located below the feed inlet of the vibrating screen, so that when the material falls from the feed inlet, it lands directly on the protective net 2, then passes through the screen holes of the protective net 2 before being screened by the screen 1. The screen holes of the protective net 2 are larger than those of the screen 1. This reduces the impact of the protective net 2 on the material screening process.

[0021] like Figure 2As shown, the connecting assembly includes a pin 3 and a pin cap 4, with the pin cap 4 located at the top of the pin 3. Multiple positioning blocks 5 are spaced apart on the pin 3, and each positioning block 5 is arranged along the axis of the pin 3. A first protective plate 17 can be detachably installed on the pin 3 below the pin cap 4, and a limiting assembly that cooperates with each positioning block 5 can also be detachably installed on the pin 3. The first protective plate 17 has holes through which the pin 3 and the positioning blocks 5 pass, facilitating the installation of the first protective plate 17 on the pin 3. When it is necessary to fix the protective net 2 to the screen 1, firstly, the first protective plate 17 is inserted into the pin 3, then the pin 3 is passed through the overlapping screen holes of the screen 1 and the protective net 2. Finally, the limiting assembly cooperates with the positioning blocks 5 on the pin 3 at appropriate positions, thus connecting and fixing the protective net 2 to the screen 1.

[0022] The limiting component for cooperating with the positioning block 5 includes a mounting base 6 detachably mounted on the pin 3, a mounting groove 7 extending along the length of the mounting base 6, and a slidable wedge 8 within the mounting groove 7. A connecting rod 9, slidably connected to the mounting base 6, is located on one side of the wedge 8. A spring 10 is fitted onto the connecting rod 9 between the wedge 8 and the mounting groove 7, and a stop is provided at the outer end of the connecting rod 9. Figure 3 and Figure 4 As shown, the mounting base 6 has a through hole at its center, through which the pin 3 and the positioning block 5 can pass. The inclined surface of the wedge 8 faces upward. When the limiting component needs to be installed on the pin 3, the center of the through hole of the mounting base 6 can be aligned with the center of the pin 3, and then the mounting base 6 can be lifted upward. The wedge 8 on the mounting base 6 will contact the positioning block 5 on the pin 3 under the action of the spring 10. When the wedge 8 contacts the positioning block 5, it will move outward along the contour of the positioning block 5 and compress the spring 10. When the wedge 8 passes the positioning block 5 it contacts, the spring 10 will push the wedge 8 to the initial position. At this time, the bottom surface of the wedge 8 will contact the top surface of the positioning block 5, so that the mounting base 6 can be limited on the pin 3 by the wedge 8. The stop provided on the connecting rod 9 will limit the wedge 8, thereby preventing the wedge 8 and the connecting rod 9 from disengaging from the mounting base 6. Once the mounting base 6 is moved to the appropriate position, the inclined block 8 will limit its movement against the adjacent positioning block 5, thereby achieving the connection between the screen 1 and the protective net 2 via the connecting assembly. The positioning block 5, which cooperates with the inclined block 8, is a cone-shaped structure, wider at the top and narrower at the bottom. When the mounting base 6 moves upward on the pin 3, the inclined block 8 will reciprocate against the inclined surface of the positioning block 5 under the action of the spring 10. In other words, after the mounting base 6 is installed on the pin 3, releasing the mounting base 6 will automatically complete its positioning on the pin 3, making the operation simple and convenient.

[0023] To facilitate the installation and removal of the inclined block 8 on the mounting slot 7, a top plate 15 is detachably provided on the mounting base 6 via a connector. The connector can be either a screw or a bolt, and no further restrictions are imposed here.

[0024] like Figure 4 As shown, the stop for limiting the connecting rod 9 is preferably a cam 11. A groove 12 is provided at the free end of the connecting rod 9, and the cam 11 is rotatably positioned within the groove 12 via a rotating shaft. A lever 13 is provided on one side of the rotating shaft. When it is necessary to disconnect the inclined block 8 from its mating positioning block 5, the cam 11 can be rotated via the lever 13. When the cam 11 rotates, the connecting rod 9 pulls the inclined block 8 outwards, and the spring 10 located between the mounting groove 7 and the inclined block 8 is also compressed. After the cam 11 rotates to the appropriate position, the apex angle of the inclined block 8 will move away from the maximum outer contour of the positioning block 5, creating a gap between the apex angle of the inclined block 8 and the maximum outer contour of the positioning block 5. The mounting seat 6 can then be removed from the pin 3. As a further improvement, a stop 14 is provided on the side wall of the cam 11. The stop 14 facilitates limiting the cam 11, makes it easier for the user to perceive the rotation angle of the cam 11, and improves the convenience of manually rotating the lever 13.

[0025] Preferably, the mounting base 6 is threaded with adjusting bolts 16 on both sides of the top plate 15, and a second guard plate 18 is provided above the mounting base 6. The tail ends of the adjusting bolts 16 are rotatably connected to the second guard plate 18. The mounting base 6 moves upward along the pin 3 and stops after the top surface of the second guard plate 18 contacts the bottom surface of the screen 1. At this time, the inclined block 8 will cooperate with its adjacent positioning block 5 to limit the mounting base 6. The positioning blocks 5 are spaced apart. In order to prevent the inclined block 8 from sliding down a distance when it cooperates with its adjacent positioning block 5, the second guard plate 18 can be adjusted by rotating the adjusting bolts 16, so that the second guard plate 18 can stably connect the screen 1 and the protective net 2.

[0026] Instructions for use: Place the protective net 2 at the feed inlet of the screen 1, then install the first guard plate 17 on the pin 3, and insert the pin 3 into the screen hole where the screen 1 and the protective net 2 overlap. Then insert the pin 3 into the through hole of the mounting base 6 and the top plate 15. When the top surface of the second guard plate 18 contacts the bottom surface of the screen 1, the mounting base 6 stops moving upward. Then adjust the second guard plate 18 by adjusting the adjusting bolt 16.
