Description
Technical Field
[0001] The utility model relates to a grille used in the process of coal transportation, belonging to the technical field of coal transfer and transportation equipment. Background Art
[0002] During the coal transportation process, the dumper overturns and transfers the coal. There is a funnel below the dumper, and the coal falls through the funnel. In order to prevent large pieces of coal from blocking the funnel, a grille is placed above the funnel. The grille is located at the tipping and discharging point of the dumper and directly above the funnel. It is found in daily work that during the tipping operation, due to the existence of large lumps or frozen coal lumps in the coal, when the lumps pass through the grille, they will get stuck on the grille, thus causing the grille to be blocked. Therefore, workers need to use tools such as sledgehammers and shovels to clean the lumps to ensure the smoothness of the grille. However, the manual cleaning operation is time-consuming and laborious, which is likely to interfere with the production efficiency of the equipment. At the same time, there are great safety hazards for the coal cleaning personnel to clean the coal on the grille. Content of the Utility Model
