[0029] In this embodiment, the lubricating oil filter includes a first upper cover 12, a first outer shell 13, a first gasket 14, and a first filter screen 15. The first upper cover 12 is fixed on the top of the first outer shell 13. The first gasket 14 is arranged between the bottom of the first upper cover 12 and the top of the first outer shell 13. The first filter screen 15 is arranged inside the first outer shell 13, and the top of the first filter screen 15 is an inclined surface, separating the upper part and the lower part inside the first outer shell 13.

The lubricating oil in the gearbox 2 reaches the magnetic filter through the fifth pipeline 9. After the magnetic filter filters the iron filings worn by the gears of the gearbox 2, the lubricating oil then enters the lubricating oil circulation oil pump 1 through the fourth pipeline 8 for circulation. It is pumped into the lubricating oil filter through the lubricating oil circulation oil pump 1 (enters the lubricating oil filter through the third pipeline 7). The lubricating oil sludge and impurities of the gearbox 2 are filtered by the lubricating oil filter. The lubricating oil then enters the cooling tank 3 through the second pipeline 6. The chilled water pipe 4 in the cooling tank 3 cools the filtered gearbox lubricating oil (the chilled water enters the chilled water pipe 4 from the chilled water inlet and then flows out from the chilled water outlet), preventing the lubricating oil from entering the gearbox 2 at too high a temperature. The cooled gearbox lubricating oil then enters the gearbox 2 through the first pipeline 5. During this process, the pressure gauge 11 detects whether the circulation oil pump 1 is overpressured. By setting up a lubricating oil replacement system outside the gearbox 2, the present utility model can achieve the purpose of quickly replacing or displacing the lubricating oil at any time, thereby improving the working efficiency of the operator, being convenient to use, and having high practical value.

[0036] In summary, the present utility model achieves the expected effect.
