Description

Technical Field

[0001] The utility model relates to a reversible grid device for removing bulky materials in conveyor belt feed, belonging to the technical field of conveying. Background Art

[0002] Bucket wheel stacker reclaimer is a loading and unloading machine that uses a bucket wheel to continuously reclaim materials and a conveyor belt (belt conveyor) on the machine to continuously stack materials. Its main operating object is bulk materials (such as coal). However, there are often some large pieces of materials in bulk materials, and some large impurities may also be mixed in during transportation and storage. In order to prevent large pieces of materials or large impurities from damaging the conveyor belt, a grid device can be installed above the feeding end of the conveyor belt. During the process of reclaiming materials by the bucket wheel stacker reclaimer, the materials first pass through the grid and then fall onto the conveyor belt. The grid effectively intercepts large pieces of materials and impurities, which can prevent large impurities and materials from damaging the conveyor belt.

[0003] Traditional grille devices generally use fixed grilles. When a large number of large impurities and materials accumulate on the grille, resulting in obstructed material falling, the grille can only be cleaned manually after the machine is shut down. Not only is the cleaning efficiency low, which seriously affects the continuity of the operation, but it also increases the labor intensity and safety risks of the workers. Therefore, it is necessary to improve it. Utility Model Content

The connecting rods 10 and the grid plates 9 cooperate to form a stable structure.

[0021] In the present embodiment, a plurality of grid plates 9 and a plurality of connecting rods 10 form a grid for intercepting large pieces of materials and impurities. When the telescopic end of the hydraulic telescopic rod 6 is extended, the rotating rod 3 is rotated by the flip arm 4. When the rotating rod 3 rotates, it drives the guide plate 7 and the connecting plate 8 welded on its outer surface to rotate synchronously, thereby driving the grid plate 9 to flip, so that the large pieces of materials on the grid plate 9 are discharged, avoiding the large pieces of materials from being retained on the grid plate 9 and causing blockage. Since the grid plate 9 flips quickly, the cleaning process does not require shutdown, which solves the problem of time-consuming traditional manual cleaning of the grid and greatly improves the cleaning efficiency.
