[0002] During the operation of a bottom-blown furnace cleaning machine, the drill rod and drill bit, as core components, must endure high temperatures, high pressures, and high speeds for extended periods. Their performance stability and service life directly impact the efficiency and safety of the cleaning machine. In particular, the drill rod bearings, key components for supporting and transmitting torque, are directly affected by their lubrication, which is crucial for bearing wear, friction, and operating temperature, ultimately impacting the performance of the entire cleaning machine. Traditional lubrication methods typically rely on periodic manual oiling. This method is not only inefficient and difficult to ensure adequate lubrication of the bearings at critical moments, but also suffers from uneven oiling and contamination. This can easily lead to bearing overheating, increased wear, and even machine failure, increasing maintenance costs and the risk of production interruptions. Furthermore, the complex and changing operating environment of a bottom-blown furnace cleaning machine, characterized by high temperatures, dust, and vibration, places even higher demands on the sealing performance of the bearing housing. Conventional bearing housings often struggle to effectively prevent oil leakage and impurities, further exacerbating bearing wear and damage. Utility Model Content

[0006] Furthermore, the bearing is a tapered roller bearing.

[0007] Furthermore, a lock nut washer is provided between the lubricating oil baffle and the lock nut.

[0008] Furthermore, the oil pipeline is a flexible pipe.

[0009] Furthermore, a wear-resistant pad is provided between the shaft sleeve and the bearing.

[0010] Furthermore, a dust cover is provided on the refueling hole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:
