Description

Technical Field

[0001] This utility model relates to the field of ball mill gear lubrication technology, specifically to an automatic lubricating oil injection device for ball mill gear transmission. Background Technology

[0002] A ball mill generally consists of a horizontal cylindrical body, hollow inlet and outlet shafts, and grinding heads. The cylindrical body is a long cylinder containing grinding media. The cylinder is made of steel plate and fixed to it by steel liners. The grinding media are typically steel spheres, arranged in different diameters and proportions. During operation, material is fed into the cylinder through the hollow inlet shaft. As the ball mill rotates, the grinding media, due to inertia, centrifugal force, and friction, adhere to the cylinder liner and are carried away by the cylinder. When carried to a certain height, the grinding media are... The grinding media, propelled by gravity, crushes the material inside the mill like a projectile. Mining ball mills are suitable for grinding various ores and other materials and are widely used in the mineral processing industry. Existing ball mills typically include a mill body, a motor, and a reducer. The motor drives the mill body to rotate through the reducer. The reducer and the mill body are usually connected by a gear pair (large and small gears). The gear pair is usually not lubricated, which leads to severe wear, short service life of the gears, and high failure rate of the ball mill.

[0003] In response, a search revealed that CN220294847U discloses a ball mill with an automatic lubrication mechanism. This mechanism includes a ball mill base and a ball mill drum rotatably fitted inside the base. A protective cover is bolted to the front of the ball mill base, and the inner side of the protective cover is rotatably fitted to the outer side of the ball mill drum. An opening at the bottom of the protective cover connects to a lubricating oil frame. A lead screw is rotatably fitted to the left side inside the lubricating oil frame. A transmission bar is threaded onto the surface of the lead screw, and a transmission frame is slidably connected to a protrusion on the surface of the transmission bar. Through the transmission mechanism, a piston block can be moved, squeezing the lubricating oil inside the lubricating oil frame and automatically applying it to the gears for automatic lubrication. This eliminates the need for frequent lubrication replenishment, and the protective cover also provides protection, preventing lubricating oil from splashing out.

[0004] The ball mill with an automatic lubrication mechanism disclosed above, through the setting of a geared motor, piston block and other structures, can drive lubricating oil into the protective shell to lubricate the gear structure when the motor is started. However, it has the following shortcomings in use: it requires a separate motor to drive the lubricating oil supply, it cannot effectively combine the rotation of the gear pair to automatically perform lubricating oil spraying, and the separate motor for corresponding separate operation results in poor integrated applicability and energy efficiency. In view of this, this application proposes an automatic lubricating oil spraying device for ball mill gear transmission to solve the above-mentioned problems. Utility Model Content

[0042] Furthermore, such as Figure 2 and 3 As shown, the lever-type reciprocating transverse drive assembly includes a first gear 3, a support shaft 301, and a connecting rod 302. The support shaft 301 is welded and fixed to the inner wall of the rear side of the protective shell 104. The first gear 3 is rotatably sleeved on the support shaft 301. The front end of the support shaft 301 is flush with the front side of the first gear 3. The connecting rod 302 is rotatably installed on the left side of the front side of the first gear 3. The first gear 3 meshes with the bottom left side of the large gear 102. The fuel injector 409 located below is aligned with the large gear 102 and the first gear 3.

[0043] In this embodiment, a circular through hole is provided on the front side of the first gear 3, and a second bearing is fixedly sleeved in the circular through hole. The inner ring of the second bearing is fixedly sleeved with the outer side of the support shaft 301, so as to achieve the effect of rotating and installing the first gear 3.

[0044] In this embodiment, the first gear 3, the support shaft 301 and the connecting rod 302 cooperate to drive the first gear 3, which meshes with the large gear 102, to rotate when the large gear 102 rotates. The rotation of the first gear 3 drives the connecting rod 302 to swing and cyclically move right and left.

[0045] Furthermore, such as Figure 2 and 3As shown, the circulating suction and supply assembly includes a piston block 401, a horizontal guide rod 402, a guide sleeve 403, a first one-way valve 406, an L-shaped tube 405, a second one-way valve 407, and a connecting pipe. The piston block 401 is sealed and slidably sleeved inside the fixed sleeve 4. The horizontal guide rod 402 is fixedly connected to the right side of the piston block 401. The guide sleeve 403 is fixedly connected between the front and rear inner walls of the fixed sleeve 4. Three anti-wear balls 404 are movably embedded on the top inner wall, bottom inner wall, front inner wall, and rear inner wall of the fixed sleeve 4. The horizontal guide rod 402 is located between the twelve anti-wear balls 404 and... The left end of the connecting rod 302 is rotatably mounted on the right side of the front of the horizontal guide rod 402, in contact with the anti-wear ball 404; the first one-way valve 406 is connected and fixed to the bottom left side of the oil reservoir 2, the left side of the first one-way valve 406 is the outlet and is connected and fixed to the right end of the L-shaped tube 405, the top end of the L-shaped tube 405 is connected and fixed to the bottom left side of the fixed sleeve 4, the second one-way valve 407 is connected and fixed to the top left side of the fixed sleeve 4, the right side of the second one-way valve 407 is the outlet and is connected and fixed to the left end of the connecting pipe, the right end of the connecting pipe extends into the protective shell 104 and is connected and fixed to the left end of the Y-shaped tube 408;

[0046] In this embodiment, stainless steel shafts are welded and fixed to the front left side of the first gear 3 and the front right side of the cross guide rod 402. A through hole is opened on the front right side and front left side of the connecting rod 302. A first bearing is fixedly sleeved inside the through hole. The inner ring of the first bearing is fixedly sleeved to the outer side of the corresponding stainless steel shaft, achieving the effect of rotating the connecting rod 302. Three sealing rings are adhesively sleeved on the outer side of the piston block 401, all of which slide tightly in contact with the inner side of the fixed sleeve 4, achieving a sliding seal between the outer side of the piston block 401 and the inner side of the fixed sleeve 4. A through hole is opened on the left side of the protective shell 104, which is fixedly connected to the outer side of the connecting pipe.

[0047] In this embodiment, the piston block 401, horizontal guide rod 402, guide sleeve 403, anti-wear balls 404, first one-way valve 406, L-shaped tube 405, second one-way valve 407, and connecting pipe work together to drive the horizontal guide rod 402 to move back and forth between the right and left when the connecting rod 302 cyclically moves right and left. The horizontal guide rod 402 moves back and forth between the twelve anti-wear balls 404, and the anti-wear horizontal guide work is performed by utilizing the rotatable nature of the anti-wear balls 404. The horizontal guide rod 402 drives the piston block 401 to slide back and forth between the right and left within the fixed sleeve 4. When the piston block 401 moves to the right, it sequentially draws lubricating oil from the oil reservoir 2 through the L-shaped tube 405 and the first one-way valve 406. When the piston block 401 moves to the left, it squeezes the drawn-in lubricating oil. Under the squeezing force, the lubricating oil is supplied into the Y-shaped tube 408 through the second one-way valve 407 and the connecting pipe. The plug 401 moves back and forth to the right and left to achieve cyclical unidirectional oil extraction and supply. By using the cyclical continuous oil extraction and supply method, the lubricating oil is gradually and stably drawn into and filled into the fixed sleeve 4 and then supplied. This achieves the effect of intermittently and continuously supplying oil into the Y-shaped tube 408 when the large gear 102 rotates. When the upper oil nozzle 409 supplies oil into the Y-shaped tube 408, it sprays lubricating oil at the meshing point between the large gear 102 and the drive gear 103 for lubrication. When the lower oil nozzle 409 supplies oil into the Y-shaped tube 408, it sprays lubricating oil at the meshing point between the first gear 3 and the large gear 102 for lubrication. By using the rotation of the large gear 102 to spray lubricating oil to lubricate the meshing point in one go, there is no need to set up a separate electric drive device for corresponding operation, which improves the energy-saving effect and the convenience of integrated application.

[0048] It should be noted that the oil reservoir 2, fixing sleeve 4, Y-shaped tube 408, fuel injector 409, protective shell 104, return pipe 201, first gear 3, support shaft 301, connecting rod 302, piston block 401, horizontal guide rod 402, guide sleeve 403, L-shaped tube 405 and connecting pipe are all preferably made of stainless steel. The advantages of stainless steel, such as high hardness, high wear resistance, high corrosion resistance and good maintenance-free effect, are utilized to ensure long-term application stability.

[0049] This embodiment can use the rotational power of the large gear 102 to spray lubricating oil to lubricate the meshing parts. By combining the rotation of the large gear 102 with the automatic integrated lubrication method, there is no need to set up a separate electric drive device for corresponding operation, which improves energy saving and the convenience of integrated application.

[0050] The usage method of this embodiment is as follows: When the automatic lubricating oil injection device for the ball mill gear transmission is in use, the rotating drive gear 103 drives the large gear 102 to rotate, and the large gear 102 drives the first gear 3 meshing with it to rotate. The rotation of the first gear 3 drives the connecting rod 302 to swing and cyclically move right and left. When the connecting rod 302 cyclically moves right and left, it drives the horizontal guide rod 402 to move back and forth right and left. The horizontal guide rod 402 moves back and forth right and left among the twelve anti-wear balls 404, utilizing the anti-wear balls 404... 4. A rotatable, anti-wear guide mechanism is used for the horizontal guide operation. The horizontal guide rod 402 drives the piston block 401 to slide back and forth to the right and left within the fixed sleeve 4. When the piston block 401 moves to the right, it sequentially draws lubricating oil from the oil reservoir 2 through the L-shaped pipe 405 and the first one-way valve 406. When the piston block 401 moves to the left, it squeezes the drawn-in lubricating oil. Under the squeezing force, the lubricating oil is supplied to the Y-shaped pipe 408 through the second one-way valve 407 and the connecting pipe. By utilizing the reciprocating right and left movement of the piston block 401, the cyclical one-way oil extraction and supply operation is achieved. By utilizing a continuous circulating oil supply method, lubricating oil is gradually and steadily drawn into and filled into the fixed sleeve 4 and then supplied. This achieves the effect of intermittently and continuously supplying oil to the Y-shaped tube 408 when the large gear 102 rotates. The upper nozzle 409 sprays lubricating oil at the meshing point between the large gear 102 and the drive gear 103 while supplying oil to the Y-shaped tube 408. The lower nozzle 409 sprays lubricating oil at the meshing point between the first gear 3 and the large gear 102 while supplying oil to the Y-shaped tube 408. This achieves integrated lubrication of the meshing point by utilizing the rotation of the large gear 102. By combining the automatic integrated lubrication spraying method with the rotation of the large gear 102, no separate electric drive equipment is required, improving energy efficiency and the convenience of integrated application. The return pipe 201 is used to return the sprayed lubricating oil to the oil storage tank 2 for recycling as the amount of lubricating oil dripping into the protective shell 104 gradually increases, reducing waste.

[0051] Example 2

[0052] like Figures 4 to 5As shown, this embodiment differs from Embodiment 1 in that: the other end of the return pipe 201 is connected to the top left side of the oil storage tank 2 through a filter element. The return pipe 201 is a vertical structure. The filter element includes a horizontal pipe 202, a stainless steel filter plate 205, a connecting rod 204, and an internally threaded pipe cap 203. The horizontal pipe 202 is fixed to the top left side of the oil storage tank 2. An external thread is provided on the outer side of the left end of the horizontal pipe 202. The internally threaded pipe cap 203 is threaded onto the external thread. The connecting rod 204 is rotatably connected to the inner left side of the internally threaded pipe cap 203. The stainless steel filter plate 205 is movably fitted inside the horizontal pipe 202 and fixedly connected to the right end of the connecting rod 204. A sealing gasket that is pressed tightly against the left end of the horizontal pipe 202 is adhered and fixed to the inner left side of the internally threaded pipe cap 203. The other end of the return pipe 201 is connected and fixed to the top of the horizontal pipe 202. The return pipe 201 is located to the left of the stainless steel filter plate 205.

[0053] In this embodiment, a third bearing is fixedly connected to the inner left wall of the internal threaded pipe cover 203. The inner ring of the third bearing is fixedly fitted to the outer side of the connecting rod 204, which achieves the effect of rotating the internal threaded pipe cover 203. By using the rotating connection method, the rotational torque can be avoided from being transmitted to the connecting rod 204 when rotating the internal threaded pipe cover 203.

[0054] It should be noted that the horizontal tube 202, the connecting rod 204, and the internal threaded tube cap 203 are all preferably made of stainless steel. The advantages of stainless steel, such as high hardness, high wear resistance, high corrosion resistance, and good maintenance-free performance, are utilized to ensure long-term application stability.

[0055] This embodiment can filter and intercept solid residue inside the lubricating oil during recycling and reuse, reducing the phenomenon that a large amount of solid residue impurities enter the oil storage tank 2 and affect subsequent use, thereby improving the efficiency of lubricating oil recycling.

[0056] The usage method of this embodiment is as follows: Unlike Embodiment 1, it also has the following functions: Utilizing the horizontal pipe 202, stainless steel filter plate 205, connecting rod 204, internally threaded pipe cap 203, and sealing gasket, as the sprayed lubricating oil drips into the protective shell 104 and gradually increases, it is returned downwards through the return pipe 201 to the horizontal pipe 202. The lubricating oil then flows to the right through the stainless steel filter plate 205 and back into the oil storage tank 2 for continued use. The stainless steel filter plate 205 filters and intercepts solid residues in the lubricating oil, reducing the impact of large amounts of solid residues entering the oil storage tank 2. To improve the efficiency of lubricating oil circulation, when the stainless steel filter plate 205 needs to be disassembled and cleaned, the inner threaded tube cover 203 is rotated in the opposite direction to separate it from the outer thread. The inner threaded tube cover 203 can then be moved to the left, allowing the stainless steel filter plate 205 to be moved out to the left via the connecting rod 204. This makes it easy for personnel to clean the filter plate. During installation, the stainless steel filter plate 205 is inserted back into the horizontal tube 202 to the right, and then the inner threaded tube cover 203 is rotated in the forward direction to tighten it to the outside of the left end of the horizontal tube 202. This facilitates the disassembly and cleaning of the stainless steel filter plate 205.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
