[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by starting the oil pump, the oil pump draws clean lubricating oil from the oil storage tank through hose two. The drawn lubricating oil is then transported through hose one to the sealing shell connected to the oil inlet, and then injected into the reducer body. At the same time, the old lubricating oil inside the reducer body flows out from the oil outlet, passes through the sealing shell connected to the oil outlet, and then flows back to the top of the oil storage tank through hose three. Inside the oil storage tank, the old lubricating oil is filtered by the filter screen, and impurities are intercepted on the filter screen. As the old lubricating oil continuously flows into the oil storage tank, the old oil is recycled and filtered, making the lubricating oil reusable and reducing costs.

[0024] 2. In this utility model, by pulling the handle installed inside the thin shell and connected to the baffle, the baffle slides inside the thin shell. During this process, the spring is compressed, and at the same time, the plug-in block connected to the baffle disengages from one of the plug-in slots of the limiting rod. At this time, pulling the limiting rod causes its sealing plug to be removed from the oil inlet and oil outlet, thereby opening the oil inlet and oil outlet. When the handle is released, the compressed spring returns to its original state, pushing the baffle so that the plug-in block is inserted into the other plug-in slot of the limiting rod again. This realizes the convenient opening and closing of the oil inlet and oil outlet of the reducer, preventing lubricating oil leakage and external impurities from entering the reducer, ensuring the normal operation and lubrication effect of the reducer.

[0037] Referring to Figures 4 and 5, the sealing assembly includes a limiting rod 4 and a thin shell 6. The outer side of the thin shell 6 is fixedly connected to the outer side of the sealing shell 3, and the outer side of the limiting rod 4 is slidably connected to the inside of the sealing shell 3. A sealing plug 5 is fixedly connected to one end of the limiting rod 4. A baffle 8 is slidably connected inside the thin shell 6. A spring 7 is fixedly connected to one side of the baffle 8, and a plug block 10 is fixedly connected to the other side of the baffle 8. A handle 9 is fixedly connected to the outer side of the baffle 8.

[0038] Specifically, the limiting rod 4 is used to connect the sealing plug 5 and slides within the sealing shell 3, enabling the sealing plug 5 to be inserted and removed from the oil inlet 16 and oil outlet 17, thereby controlling the opening and closing of the oil inlet 16 and oil outlet 17. The thin shell 6 is used to install the baffle 8, spring 7, plug block 10, and handle 9. The sealing shell 3 is used to protect the internal components such as the limiting rod 4 and sealing plug 5, ensuring the sealing performance of the sealing assembly and preventing lubricating oil leakage. The sealing plug 5 is used to seal the oil inlet 16 and oil outlet 17, preventing lubricating oil from leaking from the oil inlet 16 and oil outlet 17 during normal operation of the reducer. The baffle 8 is used to drive the plug block 10 to move, so as to connect and disconnect the plug block 10 from the plug groove 11 on the limit rod 4. At the same time, under the action of the spring 7, it maintains the fixed or loose state of the limit rod 4. In order to provide elastic force, the plug block 10 is used to insert into the plug groove 11 of the limit rod 4 to restrict the movement of the limit rod 4, thereby fixing the position of the sealing plug 5 and ensuring the sealing state of the oil inlet 16 and the oil outlet 17. When the handle 9 is pulled, it can be disengaged from the plug groove 11, so that the limit rod 4 can move freely. The handle 9 is used to facilitate the operator to control the movement of the baffle 8.

[0039] Referring to Figures 1-5, the end of the hose 20 away from one of the sealing shells 3 is fixedly connected to the top of the oil tank 14. The bottom of the oil tank 14 is fixedly connected to the top of the connecting plate 2. The bottom of the oil pump 13 is installed on the top of the connecting plate 2. The outer side of the plug block 10 is slidably connected to the inside of the thin shell 6. The end of the spring 7 away from the baffle 8 is fixedly connected to the inner wall of the thin shell 6. The limit rod 4 has two plug slots 11 inside. The outer side of the plug block 10 is inserted into one of the plug slots 11. The outer side of the handle 9 is slidably connected to the inside of the thin shell 6. The two sealing plugs 5 are respectively sealed to the oil inlet 16 and the oil outlet 17.

[0040] Specifically, hose 3 20 is used to transport the old lubricating oil flowing out of the oil outlet 17 of the reducer body 1 back to the top of the oil storage tank 14, realizing the circulation of lubricating oil. The oil storage tank 14 is used to store new lubricating oil and recover the old lubricating oil flowing back through hose 3 20, providing storage space for the circulation of lubricating oil. Connecting plate 2 is used to fix the oil storage tank 14 and oil pump 13, serving as support and connection. In order to provide power, oil pump 13 draws out and pressurizes the new lubricating oil in the oil storage tank 14, and delivers it to the reducer body 1 through hose 1 12. At the same time, it causes the old lubricating oil to be discharged from the reducer body 1 and flow back to the oil storage tank 14 through hose 3 20. Insert block 10 and thin shell 6 insert block 10 are used for insertion limit The insertion groove 11 of the positioning rod 4 restricts the movement of the positioning rod 4, thereby fixing the position of the sealing plug 5 and ensuring the sealing state of the oil inlet 16 and the oil outlet 17. The thin shell 6 is used to install the baffle 8, spring 7, insertion block 10 and handle 9, providing installation space and support structure for these components, while realizing the coordinated work between the components. The spring 7 provides elastic force. The positioning rod 4 is used to connect the sealing plug 5 and slide in the sealing shell 3 to realize the insertion and removal operation of the sealing plug 5 on the oil inlet 16 and the oil outlet 17, thereby controlling the opening and closing of the oil inlet 16 and the oil outlet 17. The two insertion grooves 11 inside are used to cooperate with the insertion block 10 to fix the position of the positioning rod 4.

[0041] Working principle: When it is necessary to change the oil in the reducer, the sealing assembly must be operated first. By pulling the handle 9, which is installed inside the thin shell 6 and connected to the baffle 8, the baffle 8 slides inside the thin shell 6. During this process, the spring 7 is compressed, and the plug block 10 connected to the baffle 8 disengages from one of the plug slots 11 of the limit rod 4. At this time, pulling the limit rod 4 removes the sealing plug 5 from the oil inlet 16 and the oil outlet 17, thereby opening the oil inlet 16 and the oil outlet 17. When the handle 9 is released, the compressed spring 7 returns to its original state, pushing the baffle 8, so that the plug block 10 is inserted into the other plug slot 11 of the limit rod 4 again. This realizes the convenient opening and closing of the reducer's oil inlet 16 and oil outlet 17, preventing lubricating oil leakage and external impurities from entering the reducer, ensuring the normal operation and lubrication effect of the reducer.

[0042] Subsequently, oil pump 13 is started, and oil pump 13 draws clean lubricating oil from oil tank 14 through hose 2 19. The drawn lubricating oil is transported through hose 12 to the sealing shell 3 connected to oil inlet 16, and then injected into the reducer body 1. At the same time, the old lubricating oil inside the reducer body 1 flows out from oil outlet 17, through the sealing shell 3 connected to oil outlet 17, and then through hose 3 20 back to the top of oil tank 14. In oil tank 14, the old lubricating oil is filtered by filter screen 18, and impurities are intercepted on filter screen 21. As the old lubricating oil continues to flow into oil tank 14, when the oil change is completed, limit rod 4 is reinserted into oil inlet 16 and oil outlet 17. When handle 9 is released, the compressed spring 7 returns to its original state, pushing baffle 8 so that plug block 10 is reinserted into one of the plug slots 11 of limit rod 4, and sealing plug 5 re-seals oil inlet 16 and oil outlet 17.
