Summary of the invention

The utility model aim is to provide a kind of scraper conveyor sprocket wheel auto Oil-filling System Using, solves sprocket shaft bearing It is immersed in inside lubricating oil for a long time and there is lubrication, change lubricating system to make sprocket wheel inner part structure change, use is dust-proof Circle substitutes floating sealing ring, so solve because sprocket wheel oil leak shine at sprocket wheel disassembly gug maintenance, and further decrease producer with The use of user, maintenance cost reduce the labor intensity of underground labour, improve the reliability of equipment.

The technical solution adopted in the utility model is: a kind of scraper conveyor sprocket wheel auto Oil-filling System Using, entire to be Uniting includes fuel tank 1, fuel sucking pipe 2, automatic lubricant pump 3, oil exit pipe 4, pipe-line system 5, straight-through nozzle 6, bearing block 7, dustband 8, Sprocket body 9, elbow nozzle 10；Automatic lubricant pump 3 is placed in fuel tank 1, and fuel sucking pipe 2 is connected to the bottom of fuel tank, oil exit pipe 4 It is connect with pipe-line system 5, pipe-line system 5 is attached with straight-through nozzle 6, and elbow nozzle 10 is connect with pipe-line system 5, whole Sprocket shaft bearing roller leads directly to nozzle 6 with elbow nozzle 10 and is set to bearing block 7 all under the covering of the sprayed lubricating oil of nozzle Inside leads directly to nozzle 6 towards sprocket body 9, and for elbow nozzle 10 backwards to sprocket body 9, the oil that such automatic lubricant pump 3 sprays will Sprocket shaft bearing is lubricated；Dustband 8 is set between bearing block 7 and sprocket body 9.

The utility model has the advantages that can change the excessive lubrication for the oil sump formula that original bearing uses, using on-demand oiling, avoid The waste of oil product.Due to using on-demand oiling, the structure of sprocket wheel changes, the floating sealing ring of sprocket wheel is changed to dustband, avoids chain Wheel because floating sealing ring damage oil leak shine at gug maintenance.
