A connecting pipe 8 is fixedly installed on the inner wall of the outlet pipe of the oil pump 7, and the end of the connecting pipe 8 is fixedly connected to the inner wall of the connecting pipe 3. A filling port communicating with the interior is provided on the upper end surface of the oil tank 6, and a sealing plug 9 is rotatably installed inside the filling port. A slope is provided inside the outer wall of the frame 1, and a material guide frame 10 matching the slope is fixedly installed on the outer wall of the frame 1. A filter box 12 is fixedly installed on the outer wall of the frame 1 through a fixing mechanism. The connecting mechanism includes a connecting plate 5 fixedly installed on the outer wall of the frame 1, and the upper end surface of the connecting plate 5 is fixedly installed on the oil tank 6.

The limiting mechanism includes a limiting rod 16 fixedly installed inside the filter box 12, the limiting rod 16 slides through the moving block 17, the limiting rod 16 can limit the moving block 17, so that the moving block 17 can only move axially along the outer wall of the screw 14, a cleaning brush 18 is fixedly installed on the bottom wall of the moving block 17, the outer wall of the filter box 12 is provided with a cleaning opening that cooperates with the cleaning brush 18, and a return oil pipe 19 connected to the interior is fixedly installed on the outer wall of the filter box 12, and the end of the return oil pipe 19 extends to the inside of the oil tank 6.

[0025] When the utility model is used, the sealing plug 9 can be firstly rotated to unscrew it, and then a proper amount of lubricating oil can be added to the oil tank 6 through the filling port.
