Technical Field

[0001] This utility model relates to the field of plate feeders, and in particular to a sealing structure for plate feeders. Background Technology

[0002] Plate feeders are widely used in various industries such as building materials, metallurgy, coal, mining, and chemicals. They can be used to transport various lumpy or loose materials from storage bins to crushers, conveyors, or other working machinery along horizontal or inclined directions, making them an indispensable piece of equipment in raw material processing or continuous production processes. To reduce safety risks at the production site, plate feeders are equipped with safety protective isolation and sealing covers, which also prevent dust from spreading and polluting the environment.

[0003] Existing sealing structures are inconvenient to maintain. Generally, the sealing cover is installed on the top of the plate feeder with bolts. Since the plate feeder is quite long, when it is necessary to maintain the components inside the sealing cover during use, the entire sealing cover needs to be disassembled, maintained, and then reinstalled, which is very troublesome, increases workload, and reduces maintenance efficiency. In order to solve the above problems, we propose a sealing structure for plate feeders. Utility Model Content
