Description

Technical Field

[0001] The utility model relates to the technical field of grease lubrication, in particular to a lubricating oil filling device for mining mechanical equipment. Background Art

[0002] Grease lubrication technology is a commonly used mechanical lubrication method that reduces friction and wear by forming a lubricating film on the friction surface. It uses the viscosity and lubricating properties of grease to form a thin film between moving parts, reducing direct metal contact, thereby reducing the friction coefficient and extending the service life of mechanical parts. Grease lubrication technology is suitable for various mechanical equipment and industrial applications. It has good sealing and high temperature resistance, can effectively reduce energy loss and improve equipment efficiency.

[0003] After searching, Chinese patent announcement number: CN220669132U discloses a lubricating grease filling device, including an oil tank and a vibrating oil pressure plate that is lifted and lowered in the oil tank, the vibrating oil pressure plate and the oil tank are limited to form an oil chamber with a variable volume; the oil pumping pipe of the oil tank passes through the vibrating oil pressure plate and extends into the oil chamber, and the vibrating oil pressure plate that can be lifted and lowered slides with the oil pumping pipe; when the oil pump is pumping oil, the vibrating oil pressure plate presses the lubricating grease in the oil chamber to drop. The utility model can quickly press the lubricating grease in the oil chamber to drop when the oil pump is pumping oil, by setting the vibrating oil pressure plate, to avoid empty pumping due to the formation of a cavity at the filter head of the oil pumping pipe due to untimely oil replenishment during oil pumping.

[0004] The beneficial effects in the above patent specification mention that "through the setting of the vibrating oil pressure plate, the lubricating grease in the oil chamber can be quickly pressed down when the oil pump is pumping oil, avoiding empty pumping caused by cavities at the filter head of the oil extraction pipe due to untimely oil replenishment during oil extraction, thereby ensuring the uniformity of the lubricating grease filling and lubrication operation." Although the above patent ensures the uniformity of the lubricating grease filling and lubrication operation, the lubricating oil cannot be stirred during specific use, which causes the lubricating oil to solidify and agglomerate after being placed for a slightly longer period of time, and the lubricating oil attached to the inner wall of the mixing barrel cannot be scraped off, which will cause the barrel wall to be corroded after a long time, thereby reducing the service life. For this reason, a lubricating oil filling device for mining machinery and equipment is proposed to solve the above problems. Utility Model Content

[0035] Reference Figure 2 The top of the mixing barrel 2 is fixedly connected with a top block 5, and the inner wall of the top block 5 is fixedly connected with a driving assembly. The top block 5 here plays a supporting and fixing role for the driving assembly, so that it remains stable during operation. The driving assembly includes a motor 6, and the outside of the motor 6 is fixedly connected to the inner wall of the top block 5. The driving end of the motor 6 is fixedly connected with a rotating shaft 7. When the motor 6 rotates, it can drive the rotating shaft 7 to rotate together. Both ends of the outside of the rotating shaft 7 are rotatably connected to the inner wall of the mixing barrel 2.

[0036] Reference Figure 2-Figure 3 The outside of the driving component is fixedly connected with a stirring plate 8. The rotating shaft 7 here can drive the stirring plate 8 to rotate together when rotating, so as to stir the lubricating oil inside the stirring barrel 2 to prevent it from solidifying and agglomerating. There are empty grooves 9 on the left and right sides of the stirring plate 8. A spring 10 is arranged inside the empty groove 9. The empty groove 9 here provides a space for the spring 10 to expand and contract. The inner wall of the empty groove 9 is slidably connected with an outer plate 11. The outer wall of the outer plate 11 contacts the inner wall of the stirring barrel 2. The outer plate 11 here can scrape off the lubricating oil attached to the inner wall of the stirring barrel 2 to prevent it from corroding the inner wall of the stirring barrel 2.

[0037] Reference Figure 3-Figure 4The inner wall of the outer plate 11 is fixedly connected to a limiting plate 12, one end of a spring 10 is fixedly connected to one side of the inner wall of the slot 9, and the other end of the spring 10 is fixedly connected to one side of the limiting plate 12. The slot 9 and the limiting plate 12 here support and fix the spring 10, and the outer part of the limiting plate 12 is slidably connected to the inner wall of the slot 9. The left bottom end of the mixing barrel 2 is fixedly connected to an oil pump 13, and the oil pump 13 here is used to extract the lubricating oil inside the mixing barrel 2.

[0038] Reference Figure 4-Figure 6 The output end of the oil pump 13 is fixedly connected with a hose 14, and the front end of the mixing barrel 2 is fixedly connected with a storage box 15. The storage box 15 here can prevent the lubricating oil from dripping in the workshop after the mechanical equipment is filled with lubricating oil, thereby causing environmental pollution. The other end of the hose 14 is fixedly connected with an oil control component, and the oil control component includes a handle 16. The bottom end of the handle 16 is fixedly connected with a nozzle 17. The handle 16 here is used for the staff to hold this equipment, and the inner wall of the nozzle 17 is slidably connected with a column 18.

[0039] Reference Figure 6 The left side of the column 18 is slidably connected with a ten-shaped ring 19. The column 18 must slide out of the fitting groove on the left side of the nozzle 17 before it can rotate inside the ten-shaped ring 19. The outside of the ten-shaped ring 19 is rotatably connected to the left inner wall of the nozzle 17. The other side of the column 18 is slidably connected with a sleeve ring. The sleeve ring here plays a role of limiting and stabilizing the column 18. The outside of the sleeve ring is rotatably connected to the right inner wall of the nozzle 17. The outside of the column 18 is slidably connected with a baffle 20. The baffle 20 here is used to control the output of lubricating oil.

[0040] Reference Figure 6 The four outer sides of the baffle 20 are in contact with the inner wall of the nozzle 17. A button 21 is fixedly connected to the right side of the column 18. Pulling the button 21 here drives the column 18 to move together. A swivel 22 is rotatably connected to the right side of the nozzle 17. A spring 23 is sleeved on the right side of the outer side of the column 18. The spring 23 here mainly plays a resetting role. One end of the spring 23 is fixedly connected to one side of the button 21, and the other end of the spring 23 is fixedly connected to one side of the swivel 22. The inner wall of the swivel 22 is slidably connected to the outer right side of the column 18. The button 21 and the swivel 22 here provide stable support for the spring 23 to ensure its stability during extension and retraction.

[0041] Working principle: first, open the top cover 3, then pour the lubricating oil that needs to be added to the mechanical equipment from the opening at the top of the mixing barrel 2, and then cover the top cover 3. The rubber pad 4 here ensures the sealing of this device to prevent dust from entering. Then, start the motor 6 inside the top block 5. At this time, the motor 6 will drive the rotating shaft 7, and then drive the stirring plate 8 to rotate, so as to stir the lubricating oil to prevent it from solidifying and agglomerating. During stirring, the outer plate 11 inside the empty groove 9 here will make the outer plate 11 close to the inner wall of the mixing barrel 2 when the spring 10 applies pressure to the limit plate 12, thereby preventing the lubricating oil from adhering to the inner wall of the mixing barrel 2, so as to avoid long-term adhesion to the inner wall of the mixing barrel 2 and causing corrosion, thereby reducing the service life of this device.

[0042] The oil pump 13 can then be started, and the oil pump 13 will draw the lubricating oil from the inside of the mixing barrel 2 into the hose 14, and then transport it to the handle 16, and then transport it to the inside of the nozzle 17. The storage box 15 here is used to place the handle 16 to prevent the lubricating oil from dripping from the nozzle of the nozzle 17 after the device is filled with lubricating oil, causing pollution to the workshop environment.

[0043] At this time, the nozzle 17 can be taken out and inserted into the joint connection of the mechanical equipment that needs to be filled with lubricating oil. Then the pull button 21 is pulled, so that the pull button 21 drives the left side of the column 18 to separate from the left inner wall that fits with the nozzle 17. The left side of the column 18 here is a cross, and the middle and right sides are inner arcs. Then the pull button 21 can be rotated. At this time, the pull button 21 will drive the baffle 20 to rotate inside the cross ring 19. Only by rotating 90 degrees can the state of the baffle 20 be adjusted to a vertical state, and then release your hand. The reset operation can be completed under the action of spring 23, and then the filling of lubricating oil can be started. The swivel 22 here will rotate synchronously with the spring 23 to prevent the spring 23 from breaking.

[0044] When the lubricant is added and the process needs to be finished, the oil output needs to be reduced and the nozzle 17 needs to be closed. At this time, the above operation can be repeated to close the oil output state of the nozzle 17, and then the nozzle 17 can be put back into the storage box 15.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
