[0025] Working principle: When in use, the staff starts the electric push rod 8, and the electric push rod 8 extends to push the filling pipe 11 into the oil tank to be filled. At this time, the oil pump 5 is started, and the oil pump 5 draws the hydraulic oil in the oil storage tank 4 through the oil inlet pipe 7, and transports it to the filling pipe 11 through the oil delivery pipe 6. The filling pipe 11 then fills the hydraulic oil into the oil tank through the oil drain hole 12. As the hydraulic oil in the oil tank increases, the level of the hydraulic oil rises, and the hydraulic oil in the oil tank enters the filling pipe 11 through the through hole 14, thereby pushing the floating block 13 to rise together with the rising level of the hydraulic oil. The floating block 13 floats upward inside the filling pipe 11 to block the filling pipe 11, and only the oil drain hole 12 located above the floating block 13 can drain the oil, thereby controlling the number of the oil drain holes 12 and reducing the flow rate of the oil out of the filling pipe 11, thereby effectively improving the quantitative filling accuracy of the oil.

The PLC controller 19 controls the electric push rod 8 to push the filling pipe 11 to fill the oil tank. When the weighing sensor 17 detects that the weight of the oil tank has reached the set value, the PLC controller 19 will control the solenoid valve 9 to close and cut off the oil line of the oil pipeline 6, thereby completing quantitative filling. At this time, the PLC controller 19 controls the electric push rod 8 to drive the filling pipe 11 to retract, and start the servo motor 18.
