Furthermore, the pillow block and the mud blocking disc are connected in a fastening mode through the round nuts, so that the mud blocking disc can be fixed more tightly, and the mud blocking disc is prevented from loosening.

Furthermore, the bearing body on connect and establish the oiling mouth, the oiling mouth extend to the bearing body inside and be connected with the contact of bearing inner race, can lubricate the bearing through the oiling mouth.

Furthermore, a bearing spacer bush is connected between the bearing body and the shaft.

Compared with the prior art, the utility model the advantage lie in:

(1) the lower end of the bearing body is provided with two split windows, so that the operation of a shaft can be observed, and slurry can flow out of the windows when flowing over the flange plane of the connecting pipe, thereby playing a role in balancing and pressure reduction;

(2) the mud blocking disc locked by the round nut is provided with labyrinth seals, so that slurry is effectively prevented from being immersed in the bearing along the axial direction to damage the bearing;

(3) and the two oil sealing devices protect lubricating grease from leaking downwards, ensure that the running oil quantity of the bearing is sufficient, prevent the lower slurry from immersing the bearing and play a role in double protection.

The design system effectively protects the bearing from running, and the service life of the bearing is obviously prolonged.
