Based on the above, the utility model aims to provide the carrier roller for the underground coal mine, so as to solve the technical problems that dust is most likely to enter the bearing of the rotating roller when the conventional carrier roller is used in the coal mine environment, the friction of the bearing is increased, the service life of the bearing is greatly reduced, and even the bearing is directly blocked, so that the bearing cannot be used.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a colliery is bearing roller in pit, includes the fixed axle, the fixed axle outer cover of rotating is equipped with the rotary drum, and the both ends of rotary drum all are provided with fixed axle complex first dust cover, and the outer wall of first dust cover all is provided with the flabellum, the fixed axle both ends lie in the internal connection of first dust cover have with rotary drum complex second dust cover, and the rotary drum both ends all are connected with second dust cover complex oil absorption cotton.

The utility model is further arranged that a plurality of bearings are arranged between the fixed shaft and the rotary drum.

The utility model is further characterized in that an oil injection passage matched with a gap between the fixed shaft and the rotary drum is formed in one end of the fixed shaft, and the outer end of the oil injection passage is in threaded connection with a sealing threaded plug.

The utility model is further arranged that the two ends of the outer wall of the rotary drum are both provided with anti-falling convex rings.

The utility model is further arranged that the outer surface of the rotary drum is made of frosted materials.

In summary, the utility model has the following advantages:

according to the utility model, the fan blades are driven to rotate through the first dust covers and the fan blades at the two ends of the rotating drum, the flowing air driven by the fan blades guides dust to enter the first dust covers as little as possible, the second dust covers and the oil absorbing cotton which are matched with each other are arranged at the two ends of the fixed shaft and the two ends of the rotating drum, and oil seal is formed between the second dust covers and the rotating drum through slow oiling of the oil absorbing cotton, so that the dust is further prevented from being contacted with a bearing.
