The intelligent touch screen 1 is electrically connected to the control system, and is used by operators to check the oil replenishment status to prevent equipment damage caused by lack of oil. The control system 2 is electrically connected to the electric grease replenishment system 3 and the high-pressure multi-point grease supply system 4. The electric grease replenishment system 3 is connected to the high-pressure multi-point grease supply system 4 through a pipeline, and the high-pressure multi-point grease supply system 4 supplies oil to the lubrication equipment 5 for lubrication; The electric grease replenishing system 3 includes an oil storage barrel 7, an oil replenishing pump 8 and a first motor 12. The oil storage barrel 7 is filled with lubricating grease. The oil replenishing pump 8 is vertically fixed in the middle of the barrel cover of the oil storage barrel 7, and the oil suction port of the oil replenishing pump 8 is downwardly inserted into the lubricating grease in the oil storage barrel 7. An oil pressure plate 6 is movably sleeved on the oil replenishing pump 8 in the oil storage barrel 7. The oil pressure plate 6 floats on the grease surface. An oil level indicator rod 13 is vertically fixed on one side of the top surface of the oil pressure plate 6. The upper end of the oil level indicator rod 13 extends out of the barrel cover of the oil storage barrel 7, and a scale line is provided on the oil level indicator rod 13. The first motor 12 is fixed on the barrel cover of the oil storage barrel 7. The output shaft of the first motor 12 is connected to the oil replenishing pump 8 to drive the oil replenishing pump 8 to operate. An oil outlet 9 is opened on one side of the oil replenishing pump 8 above the barrel cover of the oil storage barrel 7, an oil filling port 11 is provided on the upper end of the oil replenishing pump 8, and an oil mark 10 is provided on the upper end side wall.
[0016] The high-pressure multi-point grease supply system 4 includes an oil storage tank 14, an oil pressure pump 15, a box 16 and a second motor 17. The oil storage tank 14 is inverted and fixed on the top surface of the box 16, and the oil storage tank 14 is connected to the inside of the box 16. The oil storage tank 14 is connected to the oil outlet 9 through a pipeline. The oil pressure pump 15 and the second motor 17 are respectively fixed on both side surfaces of the box 16, and the output shaft of the second motor 17 is connected to the oil pressure pump 15 to drive the oil pressure pump 15 to operate.

[0017] The working process of the present invention is as follows: When the present invention is in use, firstly, the highest and lowest liquid levels of the grease in the oil storage barrel 7 are set, and lubricating grease is injected into the oil storage barrel 7 through the oil filling port 11. As the grease increases, the oil pressure plate 6 floats up, driving the oil level indicator rod 13 to move up and down in the barrel cover perforation. The oil level in the oil storage barrel 7 can be intuitively known through the indicating scale line on the oil level indicator rod 13. The first motor 12 is started to drive the oil replenishment pump 8 to operate. The oil replenishment pump 8 extracts the grease in the oil storage barrel 7 and discharges it from the oil outlet 9 to the oil storage tank 14. The grease in the oil storage tank 14 flows into the box body 16. When the grease in the box body 16 reaches a certain amount, the second motor 17 is started to drive the oil pressure pump 15 to operate. The oil pressure pump 15 squeezes the grease in the box body 16. The grease is divided into four parts through the liquid diverter and flows out from the four refueling ports 18 respectively, and enters the refueling and lubrication points of the lubrication equipment 5 to lubricate the lubrication equipment 5. When the grease level in the oil storage barrel 7 is higher than the maximum level or lower than the minimum level, the control system 2 receives a signal and sounds an alarm. When the level is higher than the maximum level, the oil filling port 11 is stopped. When the level is lower than the minimum level, the operator urgently fills the oil into the oil filling port 11.
