Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and in particular relates to a chain cleaner for belt conveyors. Background Technology

[0002] Chain cleaners for belt conveyors are commonly installed at the rear end of the head funnel on the return section of the belt conveyor to solve the problem of cleaning material spilled on the return journey. These chain cleaners are driven by a gear motor; the drive wheel generates torque to rotate the chain, and scrapers on the chain pull material falling into the cleaner's chamber, which is then thrown into the head funnel from the driven wheel, thus cleaning up material spilled onto the ground during the return journey. Chain cleaners for belt conveyors have advantages such as simple structure, significant cleaning effect, convenient maintenance, low cost, and long service life.

[0003] Comparing with Chinese Patent CN213922773U, a novel chain cleaner device for belt conveyors is disclosed, including a hopper with a protective cover fixedly connected to its inner wall and a reducer fixedly connected to its inner wall. By exchanging the positions of the drive wheel and the driven wheel, the receiving chain belt becomes the tight side, and the driving torque directly pulls the load, avoiding the effect of torque acting first on the slack side of the chain belt, thus preventing the slack side chain belt from accumulating. Furthermore, with the tight side shorter and the slack side longer, the load cycle of the chain belt becomes longer, the number of cycles in the same running time decreases, and wear is correspondingly reduced. By installing the drive wheel and the driven wheel parallel and fixed, a good stress environment for the components is ensured, maintenance and adjustment are convenient, the on-site environment is greatly improved, the intensity of cleaning operations is reduced, it is easy to operate, and adjustments can be made during operation, which also alleviates the pressure of maintenance and adjustment.

[0004] However, the aforementioned patent only relies on the vibration of the conveyor belt combined with gravity to drop materials, lacking the scraping and cleaning of materials on the surface of the conveyor belt return section. The cleaning effect is limited, and materials are prone to falling outside the range of the chain cleaner device, which greatly reduces the recycling efficiency. Therefore, a new device needs to be designed. Utility Model Content
