A cavity is provided inside the connecting plate 64. A nozzle 65 is fixedly connected to the connecting plate 64. There are multiple nozzles 65 and they are evenly spaced and arranged at one end of the connecting plate 64 close to the rotating shaft 3. Multiple nozzles 65 can spray lubricating oil onto the rotating shaft 3 more evenly and comprehensively. By starting the oil pump 61, lubricating oil is extracted from the inside of the oil storage tank 5 and transported to the inside of the connecting plate 64 through the tee pipe 62 and the oil outlet pipe 63, so that the lubricating oil is sprayed from the nozzle 65 onto the rotating shaft 3, thereby lubricating the rotating shaft 3.

[0035] A recovery structure 7 is provided below the rotating shaft 3. The recovery structure 7 includes a recovery box 71 fixedly connected to one end of the top of the mounting plate 1. A groove is provided on the top of the recovery box 71, and a slide is provided at one end of the recovery box 71. A filter screen 72 is slidably installed in the slide. Fixing screws are provided between the two ends of the filter screen 72 and the recovery box 71, and rubber sealing rings are provided around the filter screen 72. A shielding frame 73 is fixedly connected to the top of the recovery box 71. The two ends of the inner wall of the shielding frame 73 are tilted downward. The shielding frame 73 can shield and protect the splashed lubricating oil, and the oil flows into the recovery box 71 under the guidance of the tilted inner wall of the shielding frame 73. An oil pump is fixedly installed at one end of the rear side of the mounting plate 1 Second 74, one end of the bottom of the inner wall of the recovery box 71 is fixedly connected to a discharge pipe 75, one end of the discharge pipe 75 extends to the outside of the mounting plate 1 and the end is connected to the input end of the oil pump second 74, and the output end of the oil pump second 74 is connected to a return pipe 76, one end of the return pipe 76 extends to the top of the oil storage tank 5.
