A delivery pipe 6 is fixedly connected inside the protection seat 1, and a delivery blade 7 is provided inside the delivery pipe 6. The rear side of the delivery pipe 6 is connected to a filter shell 8, and the rear side of the filter shell 8 is connected to a corrugated hose 9;

[0031] A driving assembly is arranged on the front side of the protection seat 1, and the driving assembly includes a friction belt 10, which is fixedly connected to the surface of the transmission shaft 3, and a friction wheel 11 is arranged at the bottom of the friction belt 10. A support tube 12 is movably connected to the front side of the protection seat 1, and a transmission rod 13 is movably connected inside the support tube 12.

[0032] Specifically: the backing bearing body 2 is divided into two groups, and the surfaces are respectively installed on the protective seat 1 and the inner wall of the protective shell 4. A transmission shaft 3 is installed inside the backing bearing body 2, so that the transmission shaft 3 and the protective seat 1 can remain in an active state. A guide groove is opened inside the protective seat 1, which can guide the lubricating oil detached from the surface of the backing bearing body 2 into the liquid storage tank 5 for collection. The surface of the conveying blade 7 is in contact with the conveying pipe 6, and the top of the conveying pipe 6 is kept in communication with the liquid storage tank 5. The detached lubricating oil can flow into the conveying pipe 6. The filter shell 8 is sleeved on the surface of the conveying pipe 6, and the filter shell 8 is kept in communication with the conveying pipe 6. The filter shell 8 and the conveying pipe 6 are fixed by screws. After the metal filter 19 is blocked, the filter shell 8 can be separated from the conveying pipe 6 for easy cleaning.

[0033] For specific embodiment 2, please refer to Figure 1-6 On the basis of the specific embodiment 1, the driving assembly also includes a support plate 14, the support plate 14 is fixedly connected to the surface of the support tube 12, the top of the support tube 12 is movably connected with a movable shaft 15, the rear end of the movable shaft 15 is fixedly connected to the friction wheel 11, the surface of the movable shaft 15 is fixedly connected with a first belt pulley 16, the surface of the transmission rod 13 is fixedly connected with a second belt pulley 17, the first belt pulley 16 and the second belt pulley 17 are connected by a belt transmission, the other end of the transmission rod 13 penetrates into the interior of the conveying pipe 6 and is fixedly connected to the conveying blade 7, the surface of the transmission rod 13 A spring 18 is movably connected to the inner wall of the delivery pipe 6 through a bearing, and the surface of the support tube 12 is fixedly connected to the spring 18, and the other end of the spring 18 is fixedly connected to the protective seat 1. A metal filter screen 19 is arranged inside the filter shell 8, and the other end of the corrugated hose 9 is connected to the protective shell 4. Mounting plates 20 are fixedly connected to both sides of the protective shell 4, and fixing bolts 21 are arranged on the top of the mounting plate 20. The bottom of the fixing bolts 21 penetrates the mounting plate 20 and is threadedly connected to the protective seat 1. A fixing seat 22 is fixedly connected to the front side of the protective seat 1, and a pin rod 23 is threadedly connected to the front side of the fixing seat 22.

[0034] Specifically: the friction belt 10 and the friction wheel 11 are both made of rubber. When the friction belt 10 rotates with the transmission shaft 3, the friction wheel 11 can be driven to rotate by friction force, thereby utilizing the power of the external driving device. A movable groove is provided inside the support tube 12, and the second belt pulley 17 fixed on the surface of the transmission rod 13 can rotate inside the support tube 12. The support plate 14 is used to support the friction wheel 11 and the two sets of belt pulleys. At the same time, the support tube 12 can be used as the rotation axis of the support plate 14. When the support plate 14 rotates clockwise upward, the friction wheel 11 can be brought into contact with the friction belt 10. The clockwork spring 18 has the function of compressing and storing energy, and can play the role of elastic support for the support tube 12, so that the friction wheel 11 and the friction belt 10 are more closely fitted. The metal filter 19 is made of metal wire or metal sheet and has a fine pore structure, which can effectively filter out impurities or solid particles in the lubricating oil to ensure the purity and quality of the lubricating oil. The pin rod 23 is connected to the fixing seat 22 by a thread. When the backing bearing body 2 does not need to be lubricated, the support tube 12 can be rotated counterclockwise and blocked at the top of the support plate 14 by the pin rod 23 to achieve the isolation effect.

[0035] The working principle of the utility model is as follows: the worker injects lubricating oil into the liquid storage tank 5, and then installs the protection seat 1 inside the processing equipment, and the backing bearing body 2 installed inside the protection seat 1 supports the transmission shaft 3, and connects the transmission shaft 3 with the external driving equipment;

[0036] When the transmission shaft 3 drives the roller to rotate, it can drive the friction belt 10 to rotate. The friction belt 10 drives the friction wheel 11 to rotate through the friction force. The friction wheel 11 cooperates with the movable shaft 15 to drive the first belt pulley 16 to rotate. The first belt pulley 16 cooperates with the second belt pulley 17 to drive the transmission rod 13 to rotate. The transmission rod 13 drives the conveying blade 7 to rotate. The thrust of the rotation of the conveying blade 7 pushes the lubricating oil into the filter shell 8 and enters the protective shell 4 through the conveying pipe 6 to lubricate the backing bearing body 2. When the lubricating oil on the surface of the backing bearing body 2 flows downward, it can enter the liquid storage tank 5 again to realize the circulation of the oil. The entire lubrication process realizes the function of conveying lubricating oil by relying on the power of the external driving device. No additional equipment is required, which effectively improves the lubrication effect of the backing bearing body 2.
