The filling height adjustment system 2 is installed on the filling bracket 1, and the filling lifting system 3 is installed on the lower side of the filling height adjustment system 2. The filling height adjustment system 2 adjusts the height of the filling lifting system 3 according to the height of the container. Each filling system 4 is installed on the filling lifting system 3, thereby driving each filling system 4 to descend during filling.

[0032] Each filling system 4 includes a filling tube 41, a filling opening and closing device 42, a pressurized air extraction device 43 and a flexible sealing device 44. The filling tube 41 is divided into a disconnecting power chamber 414, an air extraction power chamber 415 and a filling chamber 416 from top to bottom by a first partition plate 412 and a second partition plate 413.

The filling lifting plate 32 is installed at the output end of the filling lifting cylinder 31, and drives the filling lifting plate 32 to descend during filling, and drives the filling lifting plate 32 to rise after filling is completed.

[0038] Specifically, the filling opening and closing device 42 includes a filling opening and closing rod 423 and a filling opening and closing piston 424.

[0039] Specifically, a one-way downward oil discharge check valve 435 is provided on the second partition plate 413 , and when the pressurized air extraction piston 432 moves downward, excess oil is discharged into the filling chamber 416 .

[0040] Specifically, the upper side of the exhaust control plug 433 is wider than the lower side of the exhaust control plug 433. The exhaust control plug 433 is hung at the end of the exhaust pipe 421. When the exhaust control plug 433 moves upward, the exhaust pipe 421 is opened, thereby realizing the opening and closing of the exhaust pipe 421.

[0041] Specifically, the flexible sealing device 44 is formed by a silicone sleeve that is sleeved on the filling opening and closing device 42. The thickness of the silicone sleeve is greater than 2 mm, which can achieve air extraction and oil absorption and prevent excess oil from dripping.
