A nozzle 13 is fixedly connected, a water separator and air filter 15 is fixedly connected to the left end of the compressed air distributor 14, a reversing valve 16 is fixedly connected to the rear side of the water separator and air filter 15, a protection component is arranged between the oil drain pipe 5 and the oil outlet pipe 10, an injection plate 11 is fixedly connected to the bottom of the lubricating oil distributor 12, the bottom of the compressed air distributor 14 is fixedly connected to the top of the injection plate 11, a base is fixedly connected to the bottom of the motor 1 and the gear pump 2, a filter screen is fixedly connected inside the oil storage tank 3, a support frame is fixedly connected to the bottom of the oil storage tank 3, and a coupling is arranged at the connection between the output end of the motor 1 and the input end of the gear pump 2.

[0025] Specifically, the motor 1 and the gear pump 2 are connected together through a base. The motor 1 is used to drive the gear pump 2 to work through a coupling. When the gear pump 2 is working, the lubricating oil inside the oil storage tank 3 is sucked into the inside through the oil suction pipe 4, and then sent to the inside of the oil outlet pipe 10 through the oil discharge pipe 5. The oil storage tank 3 is used to store the lubricating oil. A filter screen is arranged inside to filter the lubricating oil for the first time. A support frame is fixedly connected to the bottom of the oil storage tank 3 to support the oil storage tank 3 to the ground. A lubricating oil distributor 12 is arranged at the other end of the oil outlet pipe 10 to automatically distribute the lubricating oil to Each nozzle 13 is used to spray lubricating oil. Before the lubricating oil enters the nozzle 13, it will pass through the compressed air distributor 14, which is used to automatically distribute compressed air to each nozzle 13. A water-separating air filter 15 is arranged at the left end of the compressed air distributor 14, which is used to maintain the purity of the pipeline system and prevent air or other gases from entering. The water-separating air filter 15 is connected to the air compressor through a reversing valve 16, which is used to release compressed air to the nozzle 13 through the compressed air distributor 14. The injection plate 11 is used to support the lubricating oil distributor 12, the compressed air distributor 14 and the water-separating air filter 15 to the ground.

[0026] Reference Figure 1-2 The protection component includes a safety valve 9, which is fixedly connected to the inside of the oil discharge pipe 5, a one-way valve 7 is fixedly connected to the inside of the oil outlet pipe 10, an oil overflow filter cartridge 8 is fixedly connected to the inside of the oil outlet pipe 10, and a pressure gauge 6 is fixedly connected to the outer periphery of the oil outlet pipe 10.

[0027] Specifically, the safety valve 9 is arranged between the oil drain pipe 5 and the oil outlet pipe 10 to protect the pressure vessel and the pipeline system from overpressure. When the internal pressure of the system exceeds a preset threshold, it automatically opens and releases part of the lubricating oil. The one-way valve 7 is also arranged between the oil drain pipe 5 and the oil outlet pipe 10 to prevent the lubricating oil from flowing back into the gear pump 2 and preventing the gear pump 2 from rotating reversely and being damaged. The oil overflow filter cartridge 8 is arranged between the oil drain pipe 5 and the oil outlet pipe 10 to capture and filter solid particles, impurities and other contaminants in the oil to ensure that the oil in the system remains clean. A pressure gauge 6 is fixed on the outer periphery of the oil outlet pipe 10 for the operator to check the pressure in the pipeline at any time.

[0028] Working principle: when it is necessary to connect and spray lubricating oil on the gears, start the motor 1 to drive the gear pump 2 to work. The gear pump 2 will suck the lubricating oil in the oil storage tank 3 through the smoke pipe 4, and then discharge it to the oil outlet pipe 10 through the oil drain pipe 5. The lubricating oil is distributed to the oil outlet pipe through the lubricating oil distributor 12, and then the air compressor is started. The compressed air passes through the reversing valve 16 and enters the water-dividing air filter 15 to filter the compressed air. The filtered compressed air enters the compressed air distributor 14, and the oil outlet pipe of the lubricating oil distributor 12 is pressurized, so that the lubricating oil is sprayed on the working surface of the gear through the nozzle 13. The sprayed oil film is uniform, so that the friction pair is always in a good lubrication state, the wear of the gear is significantly reduced, and the gear life can be increased by more than double, saving 80% of lubricating oil compared with the traditional lubrication method.

[0029] When the internal pressure of the system exceeds the preset threshold, the safety valve 9 automatically opens and releases part of the lubricating oil. When the lubricating oil flows back, the one-way valve 7 prevents the lubricating oil from flowing back into the gear pump 2, thereby protecting the gear pump 2. When the lubricating oil enters the oil overflow filter cartridge 8, it will be filtered by the oil overflow filter cartridge 8 to ensure the quality of the lubricating oil. The pressure gauge 6 displays the pressure in the pipeline at any time, so that the operator can check the pressure in the pipeline well.
