Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a vibrating feeder and a screen grid thereof. Background Art

[0002] Vibrating feeders are widely used in screening and feeding operations in mining, metallurgy, coal, building materials, chemical, electric power and other industries. The screen plate is the most basic working component of the vibrating feeder. Traditional screen plates are mostly welded with rail steel, or made of multiple rods directly fixed to the screen frame by bolts. When working, materials smaller than the screen holes pass through the screen holes and become undersize, while materials larger than the screen holes continue to move forward on the screen plate surface and enter the next process.

[0003] In the actual production process, the screen bars of the rod-type vibrating feeder are easy to loosen, break or even fall off, which can easily cause accidents such as blocking the belt system, leaking materials, damaging the crusher, and scratching the belt. This not only causes a high failure rate of the production line, but also poses a huge safety hazard. The two-layer stepped layout structure of the screen bars forms a material-bearing area in the middle, which can easily cause material compaction, poor screening effect, severe wear on the upper surface of the screen bars, and a short service life of the screen bars (about 2000 hours). The crossbeam under the screen is the main basic structural component of the feeder. Since there is no protective plate on the bottom plate after the screen bars are installed, it causes rapid wear, damages the overall structure, and takes a long time to repair.

[0004] Based on this, the existing technology still needs to be improved. Utility Model Content
