Description

Technical Field

[0001] This utility model relates to the field of oil injector technology, specifically an adjustable oil injector. Background Technology

[0002] When mechanical equipment is in operation, the relative motion between moving parts generates friction, wear, and heat, affecting the normal operation of the machine. Therefore, it is essential to apply lubricating oil or grease between the friction surfaces of these moving parts. For applications with relatively low relative speeds and light loads, grease can be used for lubrication, with grease applied in stages. However, even with this method, for complex structures or internal grease application points, it can still be cumbersome, requiring machine shutdown and disassembly, impacting work efficiency, and even causing damage to machine parts. Failure to lubricate in a timely manner will also lead to damage to machine parts.

[0003] In existing technologies, conventional lubrication of underground coal mine machinery is carried out by maintenance personnel using grease guns or pneumatic lubricators. Taking a DSJ-80 belt conveyor in a tunneling face as an example, a total of 12-15 rollers need to be lubricated regularly. Lubricating all rollers takes 3-4 hours, which is inefficient. When lubricating the inside of the belt, there are safety risks for personnel standing in the roadway to help with the lubrication. At the same time, due to the lack of personnel skills and the difficulty in observing the amount of oil injected into the rollers, the quality of lubrication cannot be well controlled. Furthermore, the lack of stirring and filtering functions for the lubricating oil leads to stratification or solidification of the lubricating oil, causing blockages and resulting in poor lubrication.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses an adjustable oil injector, including a base frame 1. Weighing sensors 2 are evenly arranged on the upper surface of the base frame 1, and an oil storage cylinder 3 is installed between the upper surfaces of the weighing sensors 2. A sealing cap 4 is provided on the upper surface of the oil storage cylinder 3. A stirring mechanism 5 is installed on the lower side wall of the oil storage cylinder 3. An extraction mechanism 6 is installed on the lower inner wall of the base frame 1. The extraction mechanism 6 is connected to a liquid distribution pipe 7. A detection mechanism 8 is evenly arranged on the left side of the liquid distribution pipe 7. An oil pipe 10 is installed on the left side of the detection mechanism 8 through a quick connector assembly 9. An oil outlet 11 is provided on the left side of the oil pipe 10. A control mechanism 12 is installed on the lower side wall of the base frame 1 near the right side.

[0023] Specifically, the stirring mechanism 5 includes a motor 501, a rotating shaft 502, stirring blades 503, and a scraper 504. The motor 501 is fixedly installed on the lower surface of the oil storage tank 3. The rotating shaft 502 is fixedly installed on the upper surface of the output shaft of the motor 501, and the rotating shaft 502 is inserted into the oil storage tank 3. Stirring blades 503 are provided on both the left and right sides of the rotating shaft 502. The scraper 504 is fixedly installed on the side of the stirring blades 503 near the oil storage tank 3, and the scraper 504 is movably attached to the inner wall of the oil storage tank 3.

[0024] In this embodiment, the output shaft of the motor 501 drives the rotating shaft 502 to rotate, which in turn drives the stirring blade 503 to rotate. The stirring blade 503 drives the scraper 504 to rotate, which can stir the lubricating oil in the oil storage tank 3, making the lubricating oil less prone to separation or solidification, and reducing the residue of lubricating oil.

[0025] Specifically, the extraction mechanism 6 includes an oil pump assembly 601, an oil filter 602, a hose 603, and a connecting pipe 604. The oil pump assembly 601 and the oil filter 602 are installed on the lower inner wall of the base frame 1. The oil pump assembly 601 and the oil filter 602 are connected. The oil filter 602 is connected to the oil storage tank 3 through the hose 603. The oil pump assembly 601 is connected to the liquid distribution pipe 7 through the connecting pipe 604.

[0026] In this embodiment, the hose 603 allows the lubricating oil in the oil reservoir 3 to flow into the oil filter 602, and then the oil pump assembly 601 draws the lubricating oil from the oil filter 602. The lubricating oil flows into the distribution pipe 7 through the connecting pipe 604. A plug is threaded on the right side of the oil filter 602. Opening the plug makes it easy to replace and clean the filter element inside the oil filter 602.

[0027] Specifically, a rectangular opening 13 is provided on the upper side wall of the base frame 1 at a position corresponding to the stirring mechanism 5 and the extraction mechanism 6.

[0028] In this embodiment, the rectangular opening 13 meets the installation requirements of the stirring mechanism 5 and the extraction mechanism 6.

[0029] Specifically, a fixing rod 14 is fixedly installed on the upper surface of the liquid distribution pipe 7 near the front and rear positions, and the upper surface of the fixing rod 14 is fixedly connected to the upper inner wall of the base frame 1.

[0030] In this embodiment, the fixing rod 14 fixes the liquid distribution pipe 7, so that the liquid distribution pipe 7 is installed stably and securely.

[0031] Specifically, the detection mechanism 8 includes a conduit 801, a solenoid valve 802, and an electronic flow meter 803. The conduit 801 is installed on the left side of the liquid distribution pipe 7, and the solenoid valve 802 and the electronic flow meter 803 are installed on the conduit 801 from right to left.

[0032] In this embodiment, the opening and closing of the solenoid valve 802 controls the flow of lubricating oil in the conduit 801, and the electronic flow meter 803 counts the flow rate of the lubricating oil.

[0033] Specifically, the control mechanism 12 includes a control box 121, a controller 122, an information processing module 123, a wireless communication module 124, a timing module 125, an operation panel 126, and a power connector 127. The control box 121 is installed on the lower inner wall of the base frame 1. The controller 122, information processing module 123, wireless communication module 124, and timing module 125 are installed inside the control box 121. The operation panel 126 and power connector 127 are installed from top to bottom on the right side wall of the control box 121. The controller 122 is electrically connected to the information processing module 123, wireless communication module 124, timing module 125, operation panel 126, power connector 127, weighing sensor 2, motor 501, oil pump assembly 601, solenoid valve 802, and electronic flow meter 803.

[0034] In this embodiment, the wireless communication module 124 is wirelessly connected to an external mobile terminal device, which can be a mobile phone or a tablet computer. The APP on the mobile phone or tablet computer sends commands to the controller 122 through the wireless communication module 124. The controller 122 controls the oil pump assembly 601, the solenoid valve 802 and the electronic flow meter 803 through the information processing module 123. The timing module 125 causes the controller 122 to start and stop the motor 501 at regular intervals.

[0035] In use, connect the oil outlet 11 to the roller requiring lubrication. When lubrication is needed, the APP on a mobile phone or tablet sends a command to the controller 122 via the wireless communication module 124. The controller 122 opens the oil pump assembly 601, solenoid valve 802, and electronic flow meter 803. The lubricating oil in the oil reservoir 3 flows into the oil filter 602 through the hose 603. The oil pump assembly 601 then draws the lubricating oil from the oil filter 602. The lubricating oil flows into the distribution pipe 7 through the connecting pipe 604, and then into the conduit 801 through the distribution pipe 7. The electronic flow meter 803 measures the lubricating oil and sends the information back to the controller 122. The lubricating oil is then injected into the roller through the oil outlet 11 on the oil pipe 10. This achieves remote control of the roller lubrication, records the amount of oil injected into the roller at any given time, and can simultaneously lubricate multiple rollers. Oil filling is performed to improve oil filling efficiency. The weighing sensor 2 weighs the oil storage tank 3. When the weight of the oil storage tank 3 is less than the set value, the information is fed back to the controller 122. After being processed by the information processing module 123, it is sent to the mobile terminal through the wireless communication module 124 to remind the staff to fill the oil storage tank 3 with oil in time, thus adding a lubricating oil supply function. The timing module 125 causes the controller 122 to turn on the motor 501 at regular intervals. The output shaft of the motor 501 drives the rotating shaft 502 to rotate, which in turn drives the stirring blade 503 to rotate. The stirring blade 503 drives the scraper 504 to rotate, which can stir the lubricating oil in the oil storage tank 3, making the lubricating oil less likely to separate or solidify, and reducing the residue of lubricating oil. In addition, the oil filter 602 filters impurities in the lubricating oil, effectively avoiding clogging and making oil filling smoother.

[0036] In summary, this adjustable oiler uses remote control to inject oil into the drum, records the amount of oil injected into the drum each time, and allows multiple drums to be injected simultaneously, improving oil injection efficiency. It also adds a lubricant supply function, as well as a stirring and filtering function for the lubricant, effectively preventing clogging and making oil injection smoother.
