[0002] Due to the properties of the equipment, the moisture brought out by the chain plate transmission process of the slag scraper will penetrate into the inner guide wheel and return sprocket bearings; the head drive wheel bearing is in a high-temperature steam position, which causes steam corrosion to the bearing lubrication. In the industry, to solve this problem, the method adopted is to add enough grease at a time so that the grease is squeezed out from the inside to the outside through the bearing to form a "seal" effect; however, during the operation of the equipment, this "seal protection" does not last long. During the refueling process, special anti-scalding work clothes need to be worn to protect the operator's physical safety, and the amount of grease used for different bearing sizes is different, and the best comprehensive lubrication protection effect cannot be achieved manually.

[0003] The existing protective lubrication device for slag machine bearings has a high risk of manual grease addition, cannot automatically add grease, cannot prevent moisture from entering the bearing and affecting the lubrication effect, and the oil supply pipe has no protective ability and weak impact resistance. The device of the utility model can automatically add grease, avoid the risk of manual addition, can effectively prevent moisture from entering the bearing and affecting the lubrication effect, and the oil supply pipe has protective ability, which can reduce external impact.
