Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically to a vibrating screen damping mechanism and a vibrating screen. Background Technology

[0002] Vibrating screens, as important screening equipment, are often used to grade and screen feeds of different particle sizes. However, the design of the damping mechanism of traditional vibrating screens has many shortcomings. The damping mechanism of traditional vibrating screens mostly uses spring damping. The two ends of the damping springs are directly connected between the bottom cylinder and the large plate of the vibrating screen by bolts. There are usually many damping springs connected between the bottom cylinder and the large plate. Since the damping springs need to be replaced regularly, but the springs of the vibration screen damping mechanism cannot be mixed with new ones, otherwise it will affect the performance and life of the vibrating screen. Therefore, all springs need to be replaced when replacing them. However, this connection method requires a lot of time and effort to disassemble and assemble the bolts every time the springs are replaced, which increases the workload of workers and maintenance time.

[0031] The working principle and usage process of this utility model:

[0032] When installing the shock absorption mechanism, first insert the cylindrical 6 at both ends of each spring 4 into the two corresponding U-shaped notches 301 on the two fixing rings 3. Since the length of the cylindrical 6 is slightly greater than the thickness of the fixing ring 3, it can be ensured that the cylindrical 6 can be stably placed in the U-shaped notches 301 after installation. After all twelve springs 4 are installed, pass the four threaded pins 8 fixed at the top of the bottom cylinder 1 and the bottom of the large plate 2 through the four round holes 302 on the corresponding fixing rings 3, and tighten them with nuts to complete the initial installation of the shock absorption mechanism. At this time, the round baffles 7 at both ends of each spring 4 are just embedded in the corresponding round grooves 9 at the top of the bottom cylinder 1 and the bottom of the large plate 2, and the twelve springs 4 are fixed between the bottom cylinder 1 and the large plate 2.

[0033] When installing the vibrating screen, first, the vibrating motor 10 is bolted to the through hole in the middle of the large plate 2. The bottom frame 11 is bolted to the top of the large plate 2. Since the large plate 2 is a circular plate with a downward-curving center, the vibrating motor 10 and the bottom frame 11 do not contact each other after installation to avoid mutual interference. The upper frame 12 is mounted on top of the bottom frame 11 via a retaining ring, and the dust cover 13 is mounted on top of the upper frame 12 via a retaining ring. The bottom of the bottom frame 11 is conical, and a fine material outlet is provided on the side. The conical design of the bottom of the bottom frame 11 helps the material falling into the bottom frame 11 to be discharged from the fine material outlet. The bottom of the upper frame 12 is a screen, and a coarse material outlet is provided on the side; screening materials. During operation, coarse particles will remain on the screen and eventually be discharged from the coarse material outlet. Fine particles will pass through the screen and fall into the bottom frame 11. The dust cover 13 has a feed inlet at the top center, allowing the material to be screened to enter the vibrating screen. At this point, the entire vibrating screen is installed. When using the vibrating screen, add the material to be screened through the feed inlet at the top of the dust cover 13, start the vibrating motor 10, and the vibrating motor 10 will drive the large disc 2 to vibrate. The large disc 2 will transmit the vibration to the bottom frame 11 and the upper frame 12, causing the material to be screened on the screen of the upper frame 12. Fine particles will fall through the screen into the bottom frame 11 and be discharged from the fine material outlet, while coarse particles will remain on the screen and be discharged from the coarse material outlet on the side of the upper frame 12.

[0034] When it is necessary to disassemble the spring 4 for replacement or repair, simply unscrew the nuts on the threaded post 8 on the base cylinder 1 and the large plate 2, separate the two retaining rings 3 from the base cylinder 1 and the large plate 2, and then directly pull the cylinders 6 at both ends of the spring 4 out of the U-shaped notch 301. The whole disassembly and assembly process is simple and quick.
