Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and more specifically to a cleaning device. Background Technology

[0002] In the fuel crushing operation of thermal power plants, the fuel crusher is the core equipment. Its crushing rollers, protective covers and surrounding parts are prone to the adhesion of pollutants such as coal dust and debris. Long-term accumulation will lead to a decrease in crushing efficiency, increased equipment wear, and even jamming failure. Therefore, regular cleaning is crucial to ensure the stable operation of the equipment.

[0003] In related technologies, the cleaning methods for fuel crushers in thermal power plants mostly rely on manual disassembly and rinsing, or simple spraying with fixed nozzles. The gaps between crushing rollers and between crushing rollers and baffles can easily form cleaning dead zones, making it difficult to completely remove contaminants. At the same time, the manual disassembly and cleaning process is cumbersome, labor-intensive, and requires a long downtime for cleaning, which seriously affects the efficiency of thermal power fuel supply. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a cleaning device that, through the rotation of the nozzle and the separation of two adjacent crushing rollers, can effectively clean the crushing rollers and plate components, improve cleaning efficiency, remove contaminants, reduce the accumulation of contaminants inside the equipment, and thus extend the service life of the equipment.

[0006] The cleaning device of this invention includes a base, a cover, a nozzle, and a crushing assembly. The cover is located on top of the base and has a feed inlet. The nozzle is located inside the cover and is rotatable relative to the cover. The nozzle is used to spray cleaning fluid into the cover. The crushing assembly includes at least two plate components and at least two crushing rollers. The crushing rollers are located on the plate components, and at least two crushing rollers are arranged in a one-to-one correspondence with at least two plate components. The at least two plate components are arranged sequentially, and at least one of two adjacent plate components is movable relative to the cover so that the nozzle can rinse the crushing rollers after the adjacent two crushing rollers move away from each other.

[0007] In use, the cleaning device of this invention has a base providing support, a cover covering the crushing assembly, a feed inlet allowing fuel to enter, and a nozzle located inside the cover that can rotate to spray cleaning fluid. When fuel enters the crusher for crushing, the nozzle starts working, spraying cleaning fluid into the cover. The cleaning fluid covers the crushing rollers and plate components through the rotating nozzle. The movement of the crushing rollers and plate components allows at least one plate component in the crushing assembly to move relative to the cover. As adjacent crushing rollers gradually move away, the moving plate component allows the nozzle to reach more gaps between the crushing rollers, thereby removing contaminants, reducing the formation of cleaning dead zones, and ensuring that contaminants are thoroughly removed.

[0008] Compared with related technologies, the rotation of the nozzle and the separation of two adjacent crushing rollers can effectively clean the crushing rollers and plate components, improving cleaning efficiency, removing contaminants, reducing the accumulation of contaminants inside the equipment, and thus extending the service life of the equipment.

[0009] The crushing assembly of the cleaning device in this embodiment of the invention further includes a drive shaft, a first gear, a driven shaft, a second gear, and a reduction motor. The drive shaft passes through the plate component and is connected to the crushing roller. The first gear is located on the drive shaft. The driven shaft passes through the plate component and is connected to the crushing roller. The second gear is located on the driven shaft and meshes with the first gear. The reduction motor is located on the base, and the output end of the reduction motor is connected to the drive shaft so that the reduction motor drives the drive shaft to rotate. The reduction motor is movable relative to the base so that when the at least two plate components move, the reduction motor and the drive shaft can move synchronously.

[0010] The cleaning device of this embodiment of the invention further includes a transmission component, which is disposed on the base. After the first gear and the second gear are moved away from each other, the transmission component can be transmittedly connected between the first gear and the second gear, so that the first gear can drive the second gear to rotate through the transmission component.

[0011] The transmission assembly of the cleaning device in this embodiment of the invention includes a support plate, a support telescopic member, a third gear, and a first rotating shaft. The support plate is located at the end of the base away from the cover. The support telescopic member is located on the support plate and is rotatable relative to the support plate. The third gear is located at the telescopic end of the support telescopic member and is rotatable relative to the support telescopic member. The third gear is movable to mesh with the first gear and the second gear, so that the first gear can drive the third gear to rotate through the second gear. There are two first rotating shafts. One first rotating shaft is driven between the telescopic end of the support telescopic member and the drive shaft, and the other first rotating shaft is driven between the telescopic end of the support telescopic member and the driven shaft. When the first gear and the second gear are far apart, the drive shaft and the driven shaft can drive the third gear to move through the first rotating shaft, so that the third gear meshes with the first gear and the second gear.

[0012] The cleaning device of this invention also includes a pressing component, which is disposed on the cover. The telescopic end of the pressing component can move to drive the two plate components to increase the distance between the two crushing rollers.

[0013] The pressing assembly of the cleaning device in this embodiment of the invention includes an electric telescopic component, a crossbeam, and a linkage group. The electric telescopic component passes through the end of the cover away from the base. The crossbeam is located inside the cover and connected to the telescopic end of the electric telescopic component so that the electric telescopic component drives the crossbeam to move. There are two linkage groups, which are located opposite to the ends of the crossbeam. The linkage groups are rotatable relative to the crossbeam. Each linkage group includes two rods. The end of each rod away from the crossbeam is connected to the plate component so that the crossbeam drives the two plate components to move through the four rods.

[0014] The cleaning device of this invention further includes a limiting member group, which consists of two limiting member groups disposed opposite to each other between the two plate components. The limiting member group is used to limit and guide the plate components when the two plate components move.

[0015] The limiting component group of the cleaning device in this embodiment of the invention includes a telescopic rod, and there are multiple telescopic rods. The multiple telescopic rods are disposed between the two plate components to limit and guide the plate components when the two plate components move.

[0016] The cleaning device of this invention further includes a swing assembly, which is disposed between the cover and the crossbeam so that the swing end of the swing assembly can drive the nozzle to rotate.

[0017] The crossbeam of the cleaning device in this embodiment of the invention has a cavity.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] Reference Figures 1-8 As shown, the cleaning device of this embodiment includes a base 1, a cover 2, a nozzle 3, and a crushing assembly 4. The cover 2 is located on top of the base 1 and has a feed inlet 201. The nozzle 3 is located inside the cover 2 and is rotatable relative to the cover 2. The nozzle 3 is used to spray cleaning fluid into the cover 2. The crushing assembly 4 includes at least two plate components 401 and at least two crushing rollers 402. The crushing rollers 402 are located on the plate components 401, and at least two crushing rollers 402 are arranged in a one-to-one correspondence with at least two plate components 401. The at least two plate components 401 are arranged sequentially, and at least one of two adjacent plate components 401 is movable relative to the cover 2 so that the nozzle 3 can rinse the crushing rollers 402 after the adjacent two crushing rollers 402 are moved away.

[0030] In use, the cleaning device of this embodiment of the invention has a base 1 providing support, a cover 2 covering the crushing assembly 4, a feed inlet 201 allowing fuel to enter, and a nozzle 3 located inside the cover 2 that can rotate to spray cleaning fluid. When fuel enters the crusher for crushing, the nozzle 3 starts working, spraying cleaning fluid into the cover 2. The cleaning fluid covers the crushing roller 402 and the plate component 401 through the rotating nozzle 3. The movement of the crushing roller 402 and the plate component 401 allows at least one of the plate components 401 in the crushing assembly 4 to move relative to the cover 2. As two adjacent crushing rollers 402 gradually move away from each other, the moving plate component 401 allows the nozzle 3 to reach more gaps in the crushing rollers 402, thereby removing contaminants, reducing the formation of cleaning dead zones, and ensuring that contaminants can be thoroughly removed.

[0031] Compared with related technologies, by rotating the nozzle 3 and moving the two adjacent crushing rollers 402 further apart, the crushing rollers 402 and the plate components 401 can be effectively cleaned, improving cleaning efficiency, removing contaminants, reducing the accumulation of contaminants inside the equipment, and thus extending the service life of the equipment.

[0032] Optionally, the plate component 401 includes a first plate and a second plate. The first plate is disposed inside the cover 2 and is movable relative to the cover 2 along a first direction. The two first plates are arranged opposite each other along the first direction. There are two second plates, which are disposed opposite to the first plate. The two first plates and four second plates surround each other to receive materials fed in from the feed port 201.

[0033] The plate component 401 is arranged such that two first plates are arranged opposite each other along a first direction, and two second plates are arranged opposite each other on the first plates. In this way, the four plates enclose each other to form a closed space, which is effectively used to receive the material fed in from the feed port 201.

[0034] like Figures 1-3 As shown, the crushing component 4 of the cleaning device in this embodiment of the invention further includes a drive shaft 403, a first gear 404, a driven shaft 405, a second gear 406, and a reduction motor 407. The drive shaft 403 passes through the plate component 401 and is connected to the crushing roller 402. The first gear 404 is located on the drive shaft 403. The driven shaft 405 passes through the plate component 401 and is connected to the crushing roller 402. The second gear 406 is located on the driven shaft 405 and meshes with the first gear 404. The reduction motor 407 is located on the base 1, and the output end of the reduction motor 407 is connected to the drive shaft 403 so that the reduction motor 407 drives the drive shaft 403 to rotate. The reduction motor 407 is movable relative to the base 1 so that the reduction motor 407 and the drive shaft 403 can move synchronously when at least two plate components 401 move.

[0035] The mobility of the geared motor 407 relative to the base 1 makes the crushing component 4 of the entire cleaning device more adaptable. When at least two plate components 401 need to be moved, the geared motor 407 and the drive shaft 403 can move synchronously.

[0036] Optionally, a limit slide rail can be provided between the top of the base 1 and the geared motor 407, as long as the geared motor 407 can slide at the upper limit of the base 1.

[0037] like Figures 1-3As shown, the cleaning device of this embodiment of the invention also includes a transmission component 5. The transmission component 5 is disposed on the base 1. After the first gear 404 and the second gear 406 are far apart from each other, the transmission component 5 can be transmittedly connected between the first gear 404 and the second gear 406, so that the first gear 404 can drive the second gear 406 to rotate through the transmission component 5.

[0038] By setting up the transmission component 5, the first gear 404 and the second gear 406 can be moved away from each other, and the two adjacent crushing rollers 402 can be driven by the transmission component 5 to avoid machine stoppage. At the same time, it is convenient for the nozzle 3 to clean the two separated crushing rollers 402, thus improving work efficiency.

[0039] like Figures 1-3 As shown, the transmission assembly 5 of the cleaning device in this embodiment of the invention includes a support plate 501, a support telescopic member 502, a third gear 503, and a first rotating shaft 701. The support plate 501 is located at one end of the base 1 away from the cover 2. The support telescopic member 502 is located on the support plate 501 and is rotatable relative to the support plate 501. The third gear 503 is located at the telescopic end of the support telescopic member 502 and is rotatable relative to the support telescopic member 502. The third gear 503 is movable to mesh with the first gear 404 and the second gear 406, so that the first gear 404 can drive the third gear 503 to rotate through the second gear 406. There are two first rotating shafts 701. One first rotating shaft 701 is connected between the telescopic end of the support telescopic member 502 and the drive shaft 403. The other first rotating shaft 701 is connected between the telescopic end of the support telescopic member 502 and the driven shaft 405. When the first gear 404 and the second gear 406 are far apart, the drive shaft 403 and the driven shaft 405 can drive the third gear 503 to move through the first rotating shaft 701 so that the third gear 503 meshes with the first gear 404 and the second gear 406.

[0040] In this way, when the drive shaft 403 and the driven shaft 405 are far apart, the drive shaft 403 and the driven shaft 405 can drive the telescopic end of the support telescopic member 502 to move upward through the two first rotating shafts 701. At this time, the support telescopic member 502 drives the third gear 503 to move upward, and the third gear 503 can mesh with the first gear 404 and the second gear 406, so that the first gear 404 can mesh with the second gear 406 through the third gear 503. Thus, when cleaning the two crushing rollers 402 that are far apart, the two crushing rollers 402 can be prevented from stopping rotating at the same time.

[0041] Optionally, it also includes two transmission rods 504. The drive shaft 403 and the telescopic end of the support telescopic member 502 are connected by one transmission rod 504, and the driven shaft 405 and the telescopic end of the support telescopic member 502 are connected by the other transmission rod 504. The transmission rod 504 is rotatably connected to both the drive shaft 403 and the driven shaft 405, and also rotatably connected to the telescopic end of the support telescopic member 502. Thus, when the drive shaft 403 and the driven shaft 405 are far apart, the transmission rod 504 can drive the third gear 503 to rise and fall, so that the raised third gear 503 meshes with the first gear 404 and the second gear 406.

[0042] The cleaning device in this embodiment of the invention also includes a pressing component 6, which is disposed on the cover 2. The telescopic end of the pressing component 6 can move to drive the two plate components 401 to increase the distance between the two crushing rollers 402. By setting the pressing component 6, the distance between the two crushing rollers 402 can be increased, thereby improving practicality.

[0043] like Figures 2-3 As shown, the pressing component 6 of the cleaning device in this embodiment of the invention includes an electric telescopic member 601, a crossbeam 602, and a connecting rod assembly 603. The electric telescopic member 601 passes through the end of the cover 2 away from the base 1. The crossbeam 602 is located inside the cover 2 and connected to the telescopic end of the electric telescopic member 601 so that the electric telescopic member 601 can drive the crossbeam 602 to move. There are two connecting rod assemblies 603, which are located opposite each other at the ends of the crossbeam 602. The connecting rod assemblies 603 are rotatable relative to the crossbeam 602. The connecting rod assemblies 603 include two rods 6031. The end of the rod 6031 away from the crossbeam 602 is connected to the plate assembly 401 so that the crossbeam 602 can drive the two plate assemblies to move through the four rods 6031.

[0044] The pressing component 6 further automates the process of plate component 401. The electric telescopic component 601, through the linkage of the crossbeam 602 and the connecting rod group 603, can automatically drive the plate component 401 to move, thereby automating the distance movement and cleaning between the two crushing rollers 402 and reducing the need for manual operation.

[0045] The linkage 603 enables the crossbeam 602 to move the plate component 401, making the cleaning process more efficient. The movement of the plate component 401 ensures that the gap between the two crushing rollers 402 is thoroughly cleaned, reducing cleaning dead zones.

[0046] like Figures 3-4As shown, the cleaning device of this embodiment of the invention further includes a limiting member group 604. There are two limiting member groups 604, which are disposed opposite to each other between the two plate components. The limiting member groups 604 are used to limit and guide the plate components when they move. The setting of the limiting member group 604 provides guidance for the movement of the plate components. This limiting and guiding function helps maintain the stability of the plate component 401 during movement and prevents the plate component 401 from shifting during movement.

[0047] like Figures 3-5 As shown, the limiting component group 604 of the cleaning device in this embodiment of the invention includes multiple telescopic rods 6041. These multiple telescopic rods 6041 are disposed between two plate components to limit and guide the plate components when they move. Through the cooperation of the multiple telescopic rods 6041, the movement trajectory of the plate component 401 can be precisely controlled, ensuring that the plate component 401 remains in the correct position during movement and does not deviate.

[0048] like Figures 6-8 As shown, the cleaning device of this embodiment further includes a swing assembly 7, which is disposed between the cover 2 and the crossbeam 602 so that the swing end of the swing assembly 7 can drive the nozzle 3 to rotate. The arrangement of the swing assembly 7 allows the nozzle 3 to swing inside the cover 2, thereby increasing the coverage area of ​​the cleaning fluid spray. The swing of the nozzle 3 can cover a wider area, including hard-to-reach corners and crevices, improving the thoroughness of cleaning.

[0049] like Figures 6-8As shown, the crossbeam 602 of the cleaning device in this embodiment of the invention has a chamber 6021. The swing assembly 7 includes a first rotating shaft 701, a rack 702, a fourth gear 703, a first bevel gear 704, a second rotating shaft 705, a second bevel gear 706, and a cam 707. The first rotating shaft 701 passes through the crossbeam 602 and is rotatable relative to the crossbeam 602. The inner sidewall of the cover 2 has a groove 202, which is arranged in the vertical direction and the first rotating shaft 701 can be fitted into the groove 202. The rack 702 is disposed in the groove 202. The fourth gear 703 is located in the groove 202, connected to the first rotating shaft 701 and meshing with the rack 702. Rotation of the fourth gear 703 can drive the first rotating shaft 701 to rotate. The first bevel gear 704 is disposed at the end of the first rotating shaft 701 away from the fourth gear 703, and the first rotating shaft 701 can drive the first bevel gear 704 to rotate. The second rotating shaft 705 passes through the crossbeam 602 in a vertical direction and is rotatable relative to the crossbeam 602. A second bevel gear 706 is located on the second rotating shaft 705 and meshes with the first bevel gear 704. The first bevel gear 704 can drive the second bevel gear 706 to rotate, and the second bevel gear 706 can drive the second rotating shaft 705 to rotate. A cam 707 is located on the outside of the crossbeam 602 and connected to the second rotating shaft 705. The second rotating shaft 705 can drive the cam 707 to rotate. The nozzle 3 passes through the crossbeam 602 and is rotatable relative to the crossbeam 602. The cam 707 can drive the nozzle 3 to rotate.

[0050] The crossbeam 602 has a chamber, and the swing assembly 7 is connected to the crossbeam 602 via a first rotating shaft 701, a rack 702, a fourth gear 703, a first bevel gear 704, a second rotating shaft 705, a second bevel gear 706, and a cam 707. The first rotating shaft 701 passes through the crossbeam 602 and is rotatable. A groove 202 on the inner sidewall of the cover 2 allows the first rotating shaft 701 to fit within the groove 202. The rack 702 is located within the groove 202, and the fourth gear 703 is connected to the first rotating shaft 701 and meshes with the rack 702. When the fourth gear 703 rotates, it drives the first rotating shaft 701 to rotate via the rack 702. A first bevel gear 704 is located at the end of the first rotating shaft 701 away from the fourth gear 703, and the first bevel gear 704 meshes with the second bevel gear 706 on the second rotating shaft 705. When the first rotating shaft 701 rotates, the first bevel gear 704 drives the second bevel gear 706 to rotate, which in turn drives the second rotating shaft 705 to rotate. The cam 707 is located on the outside of the crossbeam 602 and connected to the second rotating shaft 705. The rotation of the second rotating shaft 705 drives the cam 707 to rotate. The nozzle 3 passes through the crossbeam 602 and is rotatable; the cam 707 drives the nozzle 3 to rotate via a mechanical connection. The nozzle 3 rotates on the crossbeam 602, thereby achieving oscillating cleaning.

[0051] The rotation and oscillation motion of the nozzle 3 can provide a wider cleaning coverage, and the linkage rotation of the nozzle 3 is achieved by using the crossbeam 602 to drive the two crushing rollers 402 away from each other, thereby improving the practicality of the mechanical transmission.

[0052] Optionally, a torsion spring (not shown in the figure) is provided at the rotatable connection between the crossbeam 602 and the nozzle 3. Because the nozzle 3 is far away from both ends of the crushing roller 402, the teeth of the first bevel gear 704 are set to half teeth, which can reduce the number of times the nozzle 3 swings, thereby increasing the time for it to clean the two sides of the crushing roller 4021 at a distance.

[0053] When in use, firstly, when it is necessary to clean the crushing roller 402, turn on the booster water pump to start the nozzle 3. When the telescopic end of the electric telescopic component 601 moves down, it can drive the crossbeam 602 to slide down along the inner cavity of the cover 2. The downward movement of the crossbeam 602 directly pushes the nozzle 3 at its lower part to move down synchronously. On the other hand, it drives the two sets of rods 6031 at both ends of the crossbeam 602 to unfold outward and move down. At the same time, it drives the two plate components 401 to move away from each other, completely exposing the crushing roller 402, the inner side of the plate component 401 and the inner cavity sidewall of the cover 2, eliminating cleaning dead corners.

[0054] During this process, the booster pump is turned on, and the high-pressure water flow is delivered to the nozzle 3 through the high-pressure water pipe extending from the top of the cover 2. The nozzle 3 starts to rotate and sprays out high-pressure water. At the same time, the nozzle 3 is driven by the swing component 7 in the slide groove 202 to swing left and right as it moves downward, so that the high-pressure water flow can fully cover the inner wall of the cover 2, the surface of the crushing roller 402, and the inner wall of the plate component 401, and wash away the residual fuel debris, dust and other pollutants.

[0055] After cleaning, the electric telescopic component 601 is retracted, the crossbeam 602 is reset upwards, the two crushing rollers 402 and the two plate components 401 return to their original positions synchronously, the nozzle 3 returns to its initial position along with the crossbeam 602, and the booster water pump and the reduction motor 407 are turned off. The entire cleaning process requires no manual intervention, achieving convenient and fast automated cleaning.

[0056] In use, when the electric telescopic component 601 drives the crossbeam 602 to slide downwards along the inner cavity of the cover 2, the fourth gear 703 connected to the crossbeam 602 in the swing assembly 7 moves downwards synchronously with the crossbeam 602. Since the fourth gear 703 is slidably disposed in the inner cavity of the slide groove 202 and meshes with the rack 702 fixed to the side wall of the slide groove 202, the rack 702 generates a meshing force on the downwardly moving fourth gear 703, driving the fourth gear 703 to rotate. When the fourth gear 703 rotates, it drives the first rotating shaft 701 fixedly connected to one side to rotate synchronously. Since the end of the first rotating shaft 701 away from the fourth gear 703 is fixedly provided with a first bevel gear 704 with only half of its teeth, the first rotating shaft 701 will drive one side of the first bevel gear 704 to rotate.

[0057] When the teeth of the first bevel gear 704 contact the meshing second bevel gear 706 below, it drives the second bevel gear 706 to rotate synchronously. The cam 707, which is fixedly connected to the lower end of the second bevel gear 706, rotates accordingly. During the rotation, the protruding part of the cam 707 gradually abuts against the middle outer surface of the nozzle 3, generating a lateral thrust on the nozzle 3. When the first bevel gear 704 rotates to the point where the toothless part is opposite to the second bevel gear 706, the meshing transmission between the two is interrupted, and the second bevel gear 706 and the cam 707 stop rotating. At this time, the torsion spring at the rotating connection between the crossbeam 602 and the nozzle 3 releases its elastic potential energy, pulling the nozzle 3 back to its initial position. It should also be noted that when the first bevel gear 704 meshes with the second bevel gear 706 and pushes the nozzle 3 to rotate to the other side through the cam 707, the first bevel gear 704 and the second bevel gear 706 separate. At this time, the cam 707 will continue to abut against the nozzle 3, thereby extending the cleaning of the end of the crushing roller 402 on that side by the nozzle 3.

[0058] As the crossbeam 602 continues to move downwards, the fourth gear 703 continues to roll and rotate along the rack 702, and the first bevel gear 704 also continues to rotate. When its teeth mesh with the second bevel gear 706 again, the process of pushing the nozzle 3 to swing is repeated, ultimately achieving the periodic left-right swing of the nozzle 3 during its downward movement. Simultaneously, under the action of the booster pump, the nozzle 3 continuously sprays high-pressure rotating water. Combined with the swinging motion, the high-pressure water flow can comprehensively cover the inner wall of the shroud 2, the surface of the crushing roller 402 including the gap area after the separation of the two crushing rollers 402, and the inner wall of the plate component 401, effectively flushing away residual fuel debris and dust. Because the first bevel gear 704 adopts a half-tooth design, the swing frequency of the nozzle 3 is reduced, which can extend its cleaning time for the distant areas on both sides of the crushing roller 402, further eliminating cleaning dead angles and achieving efficient and comprehensive cleaning without manual disassembly.

[0059] After cleaning, the electric telescopic component 601 drives the crossbeam 602 to move upward, the fourth gear 703 rolls and rotates in the opposite direction along the rack 702, the first bevel gear 704 rotates in the opposite direction synchronously, and the cam 707 continues to push the nozzle 3 until the nozzle 3 returns to the top of the cover 2 to reset. Under normal conditions, the nozzle 3 is kept tilted towards the first bevel gear 704 under the action of the torsion spring. The entire reciprocating swing cleaning process is completed in coordination with the lifting cleaning, without the need for additional power drive, which further improves the automation and convenience of the cleaning device.

[0060] In use, when the first gear 404 and the second gear 406 separate, they exert a pulling force on the two rods 6031 to both sides, causing the lower ends of the two rods 6031 to converge towards the middle and lift upwards. The lower end of the second inclined connecting rod is rotatably connected to the surface of the second gear 406, so the second gear 406 moves upwards synchronously with the lifting of the rods 6031. When the third gear 503 moves upwards, the support telescopic member 502 will adaptively extend to match the positional change of the third gear 503, avoiding obstruction to its movement.

[0061] When the first gear 404 and the second gear 406 separate to a preset distance, the third gear 503 moves up to a position where it meshes with the first gear 404 and the second gear 406 simultaneously. At this time, the reduction motor 407 is started. The output shaft of the reduction motor 407 drives the first gear 404, which is fixed to it, to rotate. The first gear 404 drives the third gear 503 to rotate synchronously through the meshing relationship. The rotating third gear 503 then drives the second gear 406 to rotate through the meshing action, thereby causing the crushing roller 402 connected to the first gear 404 to rotate as well, which can reduce downtime.

[0062] Through the above transmission process, both separated crushing rollers 402 can maintain rotation. With the high-pressure water jet from the nozzle 3, the circumferential surface of the crushing rollers 402 can be thoroughly washed, effectively avoiding cleaning residue caused by the inability to rotate in some areas.
