Description

Technical Field

[0001] This application relates to the field of crusher monitoring technology, and in particular to a monitoring system for monitoring the mechanical performance of a crusher. Background Technology

[0002] In existing technologies, copper bushings are often used as bearings for the internal bearings of crushers.

[0003] In the crusher, the motor drives the small gear of the crusher, the small gear drives the large gear, the large gear assembly (large gear, large gear frame, eccentric steel sleeve) drives the eccentric sleeve assembly (eccentric steel sleeve, eccentric crusher copper sleeve) and the main shaft assembly (main shaft, inner cone, inner cone liner) to revolve around the theoretical vertical line in the copper bushing. The main shaft assembly can rotate on its own axis around the center line of the main shaft in the eccentric copper sleeve.

[0004] During crusher operation, the eccentric sleeve assembly "embraces" the main shaft assembly and revolves together with the large gear. When material is added to the crushing chamber, the main shaft assembly (main shaft, inner cone) slowly rotates within the eccentric crusher's copper sleeve due to the resistance of the material. The inner cone's trajectory appears as if it is oscillating back and forth within the crushing chamber while slowly rotating. The material is crushed by the oscillating inner cone. The connection between the support sleeve and the frame is secured by a hydraulic cylinder. When uncrushable objects such as metal blocks fall into the crusher, the moving cone of the single cylinder is lifted by the bottom hydraulic piston, serving to adjust the discharge port, protect against overload, and repeatedly lift and lower to clear blockages.

[0005] The main copper bushings inside the crusher include: eccentric copper bushings, frame copper bushings, and thrust bearings. The wear condition of the copper bushings depends on the operating conditions of the crusher, and the standard for replacing copper bushings can only be determined by disassembling and inspecting the wear clearance of the copper bushings.

[0006] Disassembling a crusher to inspect for copper bushing wear is not only labor-intensive but also impacts production. If copper bushing inspections are not timely and early wear is not detected, it can lead to sudden shutdowns and damage to other components. Therefore, how to conveniently monitor the mechanical properties of copper bushings has become a technical problem that needs to be solved. Summary of the Invention

[0007] To improve the convenience of monitoring the mechanical performance of copper bushings, this application provides a monitoring system for monitoring the mechanical performance of crushers.

[0008] The monitoring system for monitoring the mechanical properties of a crusher provided in this application adopts the following technical solution: A monitoring system for monitoring the mechanical performance of a crusher includes a machine base, a cleaning component, a filtering component, an imaging component, and a control display screen mounted on the machine base. The control display screen is communicatively connected to the cleaning component, the filtering component, and the imaging component. The filtering component is used to filter copper shavings, and the imaging component is used to image the filtered copper shavings. The cleaning assembly includes a water collection tank mounted on the machine base, a height adjustment component, a rotating component mounted on the height adjustment component, a fixed component mounted on the rotating component, and a rotating cleaning component mounted at the bottom of the water collection tank; the height adjustment component, the rotating component, and the fixed component are respectively communicatively connected to the control display screen, and the fixed component is used to fix the return oil filter screen; The rotating cleaning component includes a first rotating motor, a first solenoid valve, a rotary joint, a water inlet pipe, a hollow main pipe, and multiple cleaning sections for cleaning the return oil filter screen. The first rotating motor and the first solenoid valve are respectively connected to the control display screen. The first rotating motor is located at the bottom of the water collection tank. The rotary joint is located on the drive end of the first rotating motor. The hollow main pipe is located on the rotary joint and rotatably passes through the water collection tank. The cleaning sections are located on the hollow main pipe. The water inlet pipe is connected to the water inlet of the rotary joint. The first solenoid valve is located on the water inlet pipe. The hollow main pipe and the cleaning section can extend into the return oil filter.

[0009] By adopting the above technical solution, during the monitoring of the mechanical performance of the crusher, the copper shavings from the wear of the copper bushing will be carried out by the lubricating oil and flow into the oil return filter screen on the oil tank. The copper shavings will accumulate in large quantities on the oil return filter screen. Therefore, by detecting the metal content and composition on the oil return filter screen, the wear of the copper bushing can be determined, thereby judging the wear condition of the copper bushing and determining the mechanical performance of the copper bushing, so as to facilitate timely maintenance.

[0010] Therefore, in practice, the operator only needs to first place the oil return filter screen with its opening facing upwards on the fixing component. Then, the control display screen will control the fixing component to secure the oil return filter screen. Next, the control display screen will control the rotating component to rotate, causing the opening of the oil return filter screen to face downwards. Then, the control display screen will control the adjusting component to move downwards, allowing the hollow main pipe and cleaning unit to extend into the oil return filter screen. Finally, the control display screen will control the first rotating motor to rotate, the first solenoid valve to open, the filter assembly to start, and the cleaning unit to rotate and spray water onto the oil return filter screen, thus cleaning it. The copper shavings removed are then mixed with the oil-water mixture in the water collection tank.

[0011] The filter assembly then filters the oil-water mixture to obtain copper shavings. The imaging assembly photographs the copper shavings and displays the images on the control screen. The wear condition and mechanical properties of the copper bushing can be determined based on the imaging results. This eliminates the need to disassemble the crusher to inspect the copper bushing and does not affect production, thus effectively improving the convenience of monitoring the mechanical properties of the copper bushing.

[0012] Optionally, the cleaning unit includes a first cleaning unit and a plurality of second cleaning units; The first cleaning section is a firework nozzle and is located at the end of the hollow main tube; Multiple second cleaning sections are arranged equidistantly around the side wall of the hollow main tube, and the multiple second cleaning sections are located at different positions along the length of the hollow main tube; The second cleaning unit includes a first branch pipe disposed on the hollow main pipe, a second branch pipe disposed on the first branch pipe, and a plurality of direct spray nozzles disposed on the second branch pipe.

[0013] By adopting the above technical solution, the firework nozzles are directed towards the bottom wall of the oil return filter, thus enabling the cleaning of the bottom wall and the removal of copper shavings. Meanwhile, as the hollow main pipe rotates, multiple direct nozzles on the second branch pipe clean the inner wall of the oil return filter, thereby removing copper shavings from the inner wall.

[0014] Optionally, the height adjustment component includes a hydraulic cylinder and a height adjustment support platform, and the rotating component includes a second rotating motor, a support shaft, and a rotating support platform; The hydraulic cylinder and the second rotating motor are respectively connected to the control display screen. The hydraulic cylinder is mounted on the machine base. The height adjustment support is mounted on the telescopic end of the hydraulic cylinder. The second rotating motor is mounted on the height adjustment support. The two ends of the support shaft are respectively connected to the rotating support and the rotating end of the second rotating motor. The fixing component is mounted on the rotating support.

[0015] By adopting the above technical solution, when the control display screen controls the extension and retraction of the hydraulic cylinder, the height of the support platform can be adjusted, thereby adjusting the height of the return oil filter screen. When the control display screen controls the rotation of the second rotating motor, the support platform can be rotated via the support shaft, thereby controlling the position of the return oil filter screen opening.

[0016] Optionally, the fixing component includes a third rotating motor, a rotating arm, a sliding rod, two pull rods, two sliders, and two arc-shaped locking seats; The third rotating motor is located on one side of the rotating support platform and is communicatively connected to the control display screen. The middle section of the rotating arm is rotatably connected to the rotating end of the third rotating motor. The two ends of the rotating arm are rotatably connected to the two pull rods respectively. The other end of the pull rod is rotatably connected to the slider. The two sliders are slidably connected to the two ends of the sliding rod respectively. The two arc-shaped locking seats are respectively located on the two sliders. The return oil filter is locked onto the two arc-shaped locking seats.

[0017] By adopting the above technical solution, when the control display screen controls the rotating end of the third rotating motor to rotate, the rotating arm can drive the two pull rods to swing. The two pull rods can control the sliding of the slider on the sliding rod, thereby controlling the two sliders to move closer or further away from each other, and thus realizing the two arc-shaped locking seats to fix the return oil filter screen.

[0018] Optionally, the arc-shaped snap-fit ​​seat is provided with an elastic buffer layer, which presses against the arc-shaped snap-fit ​​seat and the return oil filter.

[0019] By adopting the above technical solution, when the arc-shaped clamping seat clamps the return oil filter, the elastic buffer layer presses against the arc-shaped clamping seat and the return oil filter to form a buffer zone, which can effectively reduce the possibility of damage to the return oil filter caused by clamping.

[0020] Optionally, the filtration assembly includes a transfer component, a filter plate, a filter membrane, and a wastewater recovery tank; The filter plate and the wastewater recovery tank are both mounted on the machine platform, with the wastewater recovery tank located below the filter plate. The filter membrane is mounted on the filter plate, and the transfer component is located at the bottom of the water collection tank. The transfer component is used to transfer the oil-water mixture containing copper filings to the filter plate and the filter membrane.

[0021] By adopting the above technical solution, the transfer component can transfer the oil-water mixture in the water collection tank to the filter plate and filter membrane. After passing through the filter membrane and filter plate, the oil-water mixture is temporarily stored in the wastewater recovery tank, while the copper shavings are filtered onto the filter membrane, thereby obtaining the copper shavings in the oil return filter screen.

[0022] Optionally, the filter assembly further includes a limiting member disposed on the machine base. The limiting member includes a sliding shaft, a sliding block, and an abutting block. The sliding shaft is disposed on the machine base, the sliding block is slidably connected to the sliding shaft, and the abutting block is disposed on the sliding block. The abutting block presses the filter membrane against the filter plate.

[0023] By adopting the above technical solution, the sliding block can be moved on the sliding shaft, thereby reducing the possibility of displacement of the filter membrane during the filtration process by pressing the abutment block against the filter membrane.

[0024] Optionally, the transfer component includes a first transfer pipe and a second solenoid valve. One end of the first transfer pipe is connected to the bottom of the water collection tank, and the other end extends above the filter plate. The second solenoid valve is disposed on the first transfer pipe and is communicatively connected to the control display screen.

[0025] By adopting the above technical solution, when the control display screen controls the second solenoid valve to open, the oil-water mixture in the water collection tank can flow from the first transfer pipe to the filter plate and filter membrane, thereby realizing the control of the oil-water mixture transportation.

[0026] Optionally, the imaging component includes a camera and a fill light mounted on the machine platform, wherein the camera and the fill light are respectively communicatively connected to the control display screen.

[0027] By adopting the above technical solution, the supplementary light can provide supplementary lighting, and the camera can acquire images of copper shavings under supplementary lighting, thereby improving the imaging effect.

[0028] Optionally, the bottom of the machine is equipped with multiple casters with self-locking function.

[0029] By adopting the above technical solution, when the monitoring system needs to be moved, there is no need for staff to lift it; it can be moved simply by rolling the casters. Therefore, setting up casters can effectively improve the convenience of moving the monitoring system.

[0030] In summary, the beneficial technical effects of this application are as follows: In the process of monitoring the mechanical performance of the crusher, it is only necessary to obtain copper shavings on the return oil filter and image them. Then, the wear condition and mechanical performance of the copper bushing can be determined according to the amount and shape of the copper shavings. There is no need to disassemble the crusher to inspect the copper bushing, and it will not affect production. Therefore, it can effectively improve the convenience of monitoring the mechanical performance of the copper bushing. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] During crusher operation, copper shavings from the wear of the copper bushing will be carried out by the lubricating oil and flow into the return oil filter 1 on the oil tank. The copper shavings will accumulate in large quantities on the return oil filter 1. By designing a monitoring system to monitor the mechanical performance of the crusher, the metal content and composition on the return oil filter 1 can be detected. The wear of the copper bushing can be measured and calculated by the monitoring system at regular intervals to determine the copper shavings accumulated on the return oil filter 1, thereby determining the wear condition of the copper bushing and determining its mechanical performance, so as to facilitate timely maintenance.

[0038] This application discloses a monitoring system for monitoring the mechanical performance of a crusher.

[0039] Reference Figure 1 A monitoring system for monitoring the mechanical performance of a crusher includes a machine base 2, a cleaning assembly 3, a filtering assembly 4, an imaging assembly 5, and a control display screen 6, all mounted on the machine base 2.

[0040] The control display screen 6 is communicatively connected to the cleaning assembly 3, the filtering assembly 4, and the imaging assembly 5 to control these components. The cleaning assembly 3 cleans the return oil filter 1 to remove copper shavings accumulated therein. The filtering assembly 4 filters water and oil mixed in with it. The imaging assembly 5 acquires image data of the copper shavings, and the control display screen 6 displays this image data. The control display screen 6 has a built-in control chip and can be a tablet or laptop computer.

[0041] Reference Figure 1 and Figure 2 The cleaning assembly 3 includes a water collection tank 31, and a rotating cleaning component 32, a height adjustment component 33, a rotating component 34, and a fixing component 35, all of which are communicatively connected to the control display screen 6. The water collection tank 31 is mounted on the machine base 2. The rotating cleaning component 32 is mounted on the bottom outer wall of the water collection tank 31 and extends into the water collection tank 31. The height adjustment component 33 is mounted on the machine base 2, the rotating component 34 is mounted on the height adjustment component 33, and the fixing component 35 is mounted on the rotating component 34. Specifically, the rotating cleaning component 32 is used to clean the return oil filter 1, the height adjustment component 33 is used for height adjustment, the rotating component 34 is used for circumferential rotation, and the fixing component 35 is used to fix the return oil filter 1.

[0042] Reference Figure 1 and Figure 2 The rotating cleaning component 32 includes a first rotating motor 321, a first solenoid valve 322, a rotary joint 323, a water inlet pipe 324, a hollow main pipe 325, and a cleaning section. The cleaning section includes a first cleaning section 326 and multiple second cleaning sections 327. The first rotating motor 321 is fixedly connected to the bottom outer wall of the water collection tank 31 via a bracket, with its rotating end pointing vertically upwards. The first rotating motor 321 is communicatively connected to the control display screen 6. One end of the rotary joint 323 is coaxially fixedly connected to the drive end of the first rotating motor 321, and the other end is coaxially fixedly connected to one end of the hollow main pipe 325. The hollow main pipe 325 rotatably passes through the bottom wall of the water collection tank 31. The first cleaning section 326 is located at the other end of the hollow main pipe 325, and multiple second cleaning sections 327 are located on the side wall of the hollow main pipe 325. One end of the water inlet pipe 324 is fixedly connected to the water inlet of the rotary joint 323, and the other end is connected to an external water source.

[0043] The first solenoid valve 322 is installed on the water inlet pipe 324. The first solenoid valve 322 is communicatively connected to the control display screen 6. The first solenoid valve 322 can control the opening and closing of the water flow in the water inlet pipe 324. At this time, it is only necessary to keep the water source in a normally open setting to facilitate automatic control of the water supply. It should be understood that a diluent can be added to the water source to dilute the oil.

[0044] Reference Figure 1 and Figure 2 The first cleaning section 326 uses a spray nozzle, which can spray water in a diffused pattern to clean the bottom wall of the return oil filter 1. The second cleaning section 327 includes a first connecting pipe 3271, a second connecting pipe 3272, and multiple direct nozzles 3273. One end of the first connecting pipe 3271 is fixedly connected to the side wall of the hollow main pipe 325, and the other end is fixedly connected to the middle section of the second connecting pipe 3272. The multiple direct nozzles 3273 are fixedly connected to the second connecting pipe 3272. The first connecting pipe 3271 is perpendicular to the hollow main pipe 325, the second connecting pipe 3272 is parallel to the hollow main pipe 325, the multiple direct nozzles 3273 are arranged at equal intervals, and the multiple second cleaning sections 327 are arranged at equal intervals around each other. The multiple second cleaning sections 327 are located at different positions along the length of the hollow main pipe 325, thereby cleaning the inner wall of the return oil filter 1.

[0045] When the control display screen 6 controls the first solenoid valve 322 to open and controls the rotating end of the first rotary motor 321 to rotate, water can flow from the inlet pipe 324 into the rotary joint 323, and then from the rotary joint 323 into the hollow main pipe 325. Afterwards, part of the water in the hollow main pipe 325 is sprayed out by the firework nozzles, and the other part passes through the first branch pipe and the second branch pipe in sequence, and is sprayed out by multiple direct nozzles 3273. If the return oil filter 1 is moved above the hollow main pipe 325, so that the hollow main pipe 325 is located inside the return oil filter 1, the inner wall and bottom wall of the return oil filter 1 can be cleaned, thereby washing copper shavings into the water collection tank 31.

[0046] Reference Figure 1 and Figure 2 The height adjustment component 33 includes a hydraulic cylinder 331 and a height adjustment support platform 332. The hydraulic cylinder 331 is communicatively connected to the control display screen 6. The hydraulic cylinder 331 is mounted on the machine base 2, with its extension end pointing vertically upwards. The hydraulic cylinder 331 is located on one side of the water collection tank 31. The height adjustment support platform 332 is horizontally fixedly connected to the extension end of the hydraulic cylinder 331, and a translation component is mounted on the height adjustment support platform 332.

[0047] The rotating component 34 includes a second rotating motor 341, a support shaft 342, and a rotating support platform 343. The second rotating motor 341 is communicatively connected to the control display screen 6 and is mounted on the height adjustment support platform 342. One end of the support shaft 342 is coaxially and fixedly connected to the rotating end of the second rotating motor 341, and the other end is fixedly connected to the rotating support platform 343, with the support shaft 342 being horizontally positioned. A fixing component 35 is provided on the rotating support platform 343.

[0048] Reference Figure 2 and Figure 3The fixing component 35 includes a third rotating motor 351, a rotating arm 352, two pull rods 353, two sliding rods 354, two sliders 355, and two arc-shaped locking seats 356. The third rotating motor 351 is communicatively connected to the control display screen 6. The third rotating motor 351 is mounted on one side of the rotating support platform 343. A drive shaft is coaxially fixedly connected to the rotating end of the third rotating motor 351. The drive shaft rotatably passes through the rotating support platform 343, and the end of the drive shaft away from the third rotating motor 351 is rotatably connected to the middle section of the rotating arm 352. The two sliding rods 354 are fixedly connected side by side to the rotating support platform 343. One slider 355 is slidably connected to one end of the two sliding rods 354, and the other slider 355 is slidably connected to the other end of the two sliding connecting rods. One end of one pull rod 353 is hinged to one end of the rotating arm 352, and the other end is hinged to one of the sliders 355. One end of the other pull rod 353 is hinged to the other end of the rotating arm 352, and the other end is hinged to the other slider 355. Two arc-shaped locking seats 356 are fixedly connected to the two sliders 355 respectively, and the concave sides of the two arc-shaped locking seats 356 are located on adjacent sides of the two arc-shaped locking seats 356.

[0049] When cleaning the return oil filter 1, first place the return oil filter 1 on the two sliders 355. Then, the third rotating motor 351 drives the rotating arm 352 to rotate through the drive shaft. The rotating arm 352 drives the two pull rods 353 to rotate. The two pull rods 353 can drive the two sliders 355 to slide on the two sliding rods 354, thereby driving the two sliders 355 to move closer to each other. The two arc-shaped locking seats 356 can lock the bottom outer wall of the return oil filter 1, thereby fixing the return oil filter 1. At this time, the opening of the return oil filter 1 faces upward.

[0050] Next, the rotating end of the second rotary motor 341 rotates 180°, driving the support shaft 342 to rotate, which in turn drives the rotating support platform 343 to rotate, causing the return oil filter 1 to rotate with its opening facing downwards. Then, the telescopic end of the hydraulic cylinder 331 retracts and drives the heightening support platform 332 to move downwards, thus lowering the return oil filter 1 and positioning the support shaft 342 inside the return oil filter 1. Finally, the rotating cleaning component 32 cleans the return oil filter 1, with the telescopic end of the hydraulic cylinder 331 continuously extending and retracting to achieve comprehensive cleaning of the inner and bottom walls of the return oil filter 1. Copper shavings are temporarily collected in the water collection tank 31 by the water flow.

[0051] Similarly, after cleaning the return oil filter 1, the telescopic end of the hydraulic cylinder 331 retracts, causing the return oil filter 1 to move upwards. Then, the second rotary motor 341 rotates 180°, so that the opening of the return oil filter 1 faces upwards. The first rotary motor 321 rotates in the opposite direction, thus securing the return oil filter 1. Finally, the operator can remove the return oil filter 1 and reinstall it on the crusher's oil tank.

[0052] Meanwhile, an elastic buffer layer is bonded to the side of the arc-shaped snap-fit ​​seat 356 adjacent to the other arc-shaped snap-fit ​​seat 356. When fixing the return oil filter 1, the elastic buffer layer presses against the arc-shaped snap-fit ​​seat 356 and the return oil filter 1 to reduce the possibility of damaging the return oil filter 1 during the snap-fit ​​process. In this embodiment, the elastic buffer layer is made of rubber; in other embodiments, the elastic buffer layer may also be made of silicone.

[0053] Reference Figure 2 and Figure 4 The filter assembly 4 includes a transfer component 41, a filter plate 42, a filter membrane 43, a wastewater recovery tank 44, and a limiting component 45. The transfer component 41 is located on the bottom side wall of the water collection tank 31. The filter plate 42 is mounted on the machine base 2, and the filter membrane 43 is laid on the filter plate 42. The limiting component 45 is located on the machine base 2 and presses the edge of the filter membrane 43 against the machine base 2. The wastewater recovery tank 44 is mounted on the machine base 2 and located below the filter plate 42. The transfer component 41 is used to transport the oil-water mixture in the water collection tank 31 to the filter membrane 43. After being filtered by the filter membrane 43 and the filter plate 42, the oil-water mixture is temporarily stored in the wastewater recovery tank 44, while copper filings in the oil-water mixture are filtered onto the filter membrane 43.

[0054] The filter plates 42 have evenly distributed filter holes, and their horizontal height is lower than that of the upper surface of the machine base 2 to prevent the oil-water mixture from overflowing. The wastewater recovery tank 44 is placed directly on the machine base 2 for easy emptying of the filtered oil-water mixture. Furthermore, the bottom of the machine base 2 is equipped with multiple self-locking casters 7 for easy movement of the entire monitoring system. It should be understood that a water pipe can be installed at the bottom of the wastewater recovery tank 44 and can be connected to a sewer pipe, thus eliminating the need for emptying the filtered oil-water mixture.

[0055] Reference Figure 2 and Figure 4The transfer component 41 includes a first transfer pipe 411, a second solenoid valve 412, and multiple second transfer pipes 413. One end of each of the multiple second transfer pipes 413 is fixedly connected to the bottom of the water collection tank 31, and the other end of each is fixedly connected to one end of a second transfer pipe 413. The multiple second transfer pipes 413 are evenly distributed on the water collection tank 31 to facilitate better flow of the oil-water mixture into the first transfer pipe 411. The end of the first transfer pipe 411 away from the second transfer pipes 413 extends above the filter plate 42. The second solenoid valve 412 is installed on the first transfer pipe 411 and is communicatively connected to the control display screen 6.

[0056] Reference Figure 4 The limiting component 45 includes a sliding shaft 451, a sliding block 452, and an abutment block 453. The sliding shaft 451 is vertically fixed to the machine base 2 and is located on one side of the filter plate 42. The sliding block 452 is slidably connected to the sliding shaft 451. The abutment block 453 is connected to the sliding block 452 through a bracket, and the abutment block 453 can press the edge of the filter membrane 43 against the edge of the filter plate 42, thereby reducing the possibility of displacement of the filter membrane 43 during filtration. At the same time, a handle 4521 is also vertically fixedly connected to the sliding block 452, so that the operator can hold the handle 4521 to slide the sliding block 452.

[0057] During the cleaning process of the oil return filter screen by the cleaning component 3, the second solenoid valve 412 can be opened simultaneously, thereby conveying the oil-water mixture while it accumulates in the water collection tank 31. The copper shavings in the oil-water mixture are then filtered onto the filter membrane 43, and the oil-water mixture eventually flows into the wastewater recovery tank 44. It should be understood that the filter membrane 43 can be replaced after one filtration cycle.

[0058] Reference Figure 1 The imaging component 5 includes a camera 51 and at least one supplementary light 52. Both the camera 51 and the supplementary light 52 are mounted on the machine base 2 via brackets, and are communicatively connected to the control display screen 6. Both the camera 51 and the supplementary light 52 are positioned above the filter membrane 43. After copper shavings are collected on the filter membrane 43, the operator can control the camera 51 and the supplementary light 52 via the control display screen 6 to image the copper shavings. The monitoring results are then displayed on the control display screen 6. Analysis of the copper shavings allows for assessment of the wear and mechanical properties of the copper sleeve. Specifically, the different shapes of the copper shavings can be used to determine the causes of their formation. For example, flaky copper shavings are caused by crusher fatigue, while filamentous and crescent-shaped copper shavings are caused by crusher cutting. This analysis helps determine whether the copper sleeve needs to be replaced.

[0059] The implementation principle of a monitoring system for monitoring the mechanical performance of a crusher according to an embodiment of this application is as follows: During the monitoring of the mechanical performance of the crusher, the oil return filter 1 is cleaned by the cleaning component 3, copper shavings in the oil return filter 1 are obtained by the filtering component 4, and the copper shavings are imaged by the imaging component 5. The image is then displayed on the control display screen 6. The wear condition and mechanical performance of the copper bushing can be determined based on the imaging results. There is no need to disassemble the crusher to inspect the copper bushing, and it will not affect production. Therefore, it can effectively improve the convenience of monitoring the mechanical performance of the copper bushing.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
