Description

Technical Field

[0001] This invention relates to the field of belt conveyors, and in particular to a belt conveyor scraping and cleaning device and a belt conveyor. Background Technology

[0002] Belt conveyors are core equipment for material transport in industrial and mining production. Dust, wet materials, and lumpy residue easily adhere to the surface of the conveyor belt on the return section. Long-term residue buildup will continuously affect the normal operation of the belt. Belt cleaning is a crucial supporting process to ensure the long-term operation of belt conveyors. Currently, belt conveyor return cleaning mostly adopts a single-sided cleaning structure, which is limited in its cleaning method and cannot simultaneously clean both the inner and outer sides of the conveyor belt. It can only perform simple scraping operations on the outer surface of the conveyor belt, failing to clean materials adhering to the inner surface. The cleaning coverage is limited, and the cleaning effect is poor. Furthermore, conventional cleaning structures are mostly fixed installations, the angle of the scraping components cannot be flexibly adjusted, the transmission structure is poorly integrated, and the subsequent disassembly, assembly, and maintenance processes are cumbersome. Moreover, there is a lack of supporting belt limit and correction mechanisms and self-cleaning roller structures, making precise guidance and limiting difficult, easily leading to belt deviation. Debris easily accumulates on the surface of the guide rollers, which can exacerbate belt friction and shorten the equipment's service life. Summary of the Invention

The conveying support structure 5 is in contact with the inner surface of the conveyor belt 3.

[0021] In this embodiment, the conveying support structure 5 is fixedly connected to the first fixed rod 7 and the second fixed rod; the first fixed rod 7 is arranged parallel to the first support rod 101, and the two are separated by a second preset distance, that is, multiple conveying support structures 5 are installed equidistantly between the two fixed rods (the first fixed rod 7 and the first support rod 101), and an inner scraping assembly 6 is installed between any two conveying support structures 5. The conveying support structure 5 is a common conveying support structure with a roller structure, used to support the conveyor belt 3. The conveyor belt 3 and the conveying support structure 5 are connected by sliding contact through the roller. The inner scraping assembly 6 is used to clean the inner surface of the conveyor belt 3. The conveyor belt 3 passes through two guide assemblies 8 in sequence, and the guide assemblies 8 are slidably connected to the inner and outer surfaces of the conveyor belt 3.

[0022] In this embodiment, two symmetrically arranged support rods (first support rod 101 and second support rod 102) provide basic support for the entire device and serve as the mounting carrier for all components; side support plates (first side support plate 21, second side support plate 22, third side support plate 23) and fourth side support plate 24 are used to fix and support the belt rollers (first belt roller 41 and second belt roller 42) to ensure stable rotation of the belt rollers; the belt rollers, as the transmission components of the conveyor belt 3, drive the conveyor belt 3 to realize material conveying; the conveyor belt 3 is the core component of material conveying, used to carry and convey materials.

[0023] In this embodiment, when the device is working, the belt roller rotates to drive the conveyor belt 3 to transport materials. The conveyor belt 3 runs smoothly under the limiting and guiding action of the guide component 8. The outer scraping component 1 is adjusted to a suitable angle around the rotating shaft. The scraping disc 12 of the outer scraping component 1 is in close contact with the outer surface of the conveyor belt 3. The output shaft 14 of the outer scraping component 1 drives the scraping disc 12 to rotate. As the conveyor belt 3 moves, the scraping disc 12 continuously scrapes off the residual material on the outer surface of the conveyor belt 3, completing the initial cleaning of the belt conveyor's return stroke. The support rod provides stable support for each component throughout the entire process, ensuring that the entire cleaning device and the conveying mechanism operate in coordination.

[0024] In an optional embodiment of the present invention, the external scraping assembly 1 includes: Mounting plate 9 is disposed below the conveyor support structure 5 and is fixedly connected to the belt conveyor base; Two side plates 10 are disposed opposite to each other at both ends of the mounting plate 9; A rotating frame 11 is disposed between the two side plates 10 and rotatably connected to the side plates 10, and a transmission device is provided inside the rotating frame 11; Multiple uniformly arranged output shafts 14 are installed at equal intervals on two adjacent sides of the rotating frame 11, and one end of each output shaft 14 is rotatably connected to the transmission device. Each of the output shafts 14 is connected to a scraper disc 12 at the other end.

[0025] In this embodiment, the mounting plate 9 is disposed on the first support rod 101 and the second support rod 102 to connect the side plate 10 and the support rod. The side plate 10 is used to mount the rotating frame 11 and provide rotational support for the rotating frame 11. The rotating frame 11 can rotate around the axis of the side plate 10. The rotating frame 11 is used to mount the scraper disc 12 and adjust the contact angle between the scraper disc 12 and the conveyor belt 3. The rotating frame 11 is mounted between the two side plates 10 via the rotating shaft. Multiple output shafts 14 are equidistantly mounted on two adjacent sides of the rotating frame 11. Each output shaft 14 has a scraper disc 12 mounted on its surface. The scraper disc 12 contacts the outer surface of the conveyor belt 3. The output shaft 14 is used to fix the scraper disc 12 and drive the scraper disc 12 to rotate. The scraper disc 12 contacts the outer surface of the conveyor belt 3 to scrape off the material remaining on the outer surface of the conveyor belt 3, thereby realizing the cleaning function.

[0026] In a preferred embodiment, a second drive motor is installed inside any side plate 10, which can drive the rotating shaft and the rotating frame 11 to rotate.

[0027] In a preferred embodiment, the output shafts 14 on two adjacent sides of the rotating frame 11 are configured with a cross-mounted design, so that the entire outer surface of the conveyor belt 3 can be cleaned by rotation.

[0028] In an optional embodiment of the present invention, the rotating frame 11 has a cavity 16 inside, and two adjacent surfaces of the rotating frame 11 have through slots 13 that communicate with the cavity 16. A transmission device is provided inside each of the two through slots 13. A snap-fit ​​plate 20 is snapped into the opening of each through slot 13. Multiple uniformly arranged output shafts 14 are installed at equal intervals on each snap-fit ​​plate 20. One end of each output shaft 14 is rotatably connected to the transmission device, and the other end is connected to a scraper disc 12.

[0029] In this embodiment, the cavity 16 inside the rotating frame 11 is used to accommodate the transmission device, providing installation and movement space for internal components; the through slot 13 communicates with the cavity 16 and is used to snap-fit ​​the snap-fit ​​plate 20, while also providing a channel for the extension of the output shaft 14; bolt connection holes are provided on both ends of the snap-fit ​​plate 20 and on the side wall of the through slot 13. The two ends of the snap-fit ​​plate 20 are snap-fitted and fixedly connected to the side wall of the through slot 13 by bolts. The snap-fit ​​plate 20 is used to install the output shaft 14. The snap-fit ​​plate 20 is provided with a bearing mounting slot, and a bearing is provided in the bearing mounting slot. The bearing is interference-fitted with the bearing mounting slot. One end of the output shaft 14 is fixed to the snap-fit ​​plate 20 by the bearing and is rotatably connected to the snap-fit ​​plate 20. The bolt-fit connection between the through slot 13 and the snap-fit ​​plate 20 facilitates... Subsequent disassembly, maintenance, and replacement; the output shaft 14 is mounted on the snap-fit ​​plate 20, with one end connected to a gear and the other end connected to the scraper disc 12, used to transmit power and drive the scraper disc 12 to rotate; during operation: the snap-fit ​​plate 20 is snapped into the cavity 16 of the rotating frame 11 through the through slot 13 to ensure a firm installation; multiple output shafts 14 are evenly rotated and mounted on the snap-fit ​​plate 20, with one end of the output shaft 14 extending to the outside of the rotating frame 11 and connected to the scraper disc 12, and the other end remaining in the cavity 16 and connected to the gear assembly of the transmission device. When the gear assembly rotates, it will drive all the output shafts 14 on the snap-fit ​​plate 20 to rotate synchronously, thereby driving the scraper disc 12 to rotate, realizing the cleaning of the conveyor belt 3. The snap-fit ​​design allows for quick disassembly of the snap-fit ​​plate 20 to inspect or replace components such as the output shaft 14 and the scraper disc 12, improving the convenience of device maintenance.

[0030] In an optional embodiment of the present invention, the transmission device includes: A first drive motor 15 is disposed within the through groove 13, and the first drive motor 15 is disposed at both ends of the through groove 13. A drive gear 19 is disposed at the output end of the first drive motor 15; A driven gear 18 is provided at one end of each output shaft 14, and the driven gear 18 is connected to the driving gear 19 through a rack and belt 17.

[0031] In this embodiment, the first drive motor 15 is located at the inner edge of the snap-fit ​​plate 20, and one end of the drive gear 19 can also be connected to an output shaft 14. The drive gear 19, as the core component for power transmission, is driven to rotate by the first drive motor 15, which in turn drives the rack and belt 17 to move. The driven gear 18 meshes with the drive gear 19 through the rack and belt 17 and rotates synchronously under the drive of the drive gear 19, thereby realizing the splitting and transmission of power. The rack and belt 17 is used to connect the drive gear 19 and multiple driven gears 18 to ensure that all gears rotate synchronously, thereby driving all output shafts 14 to move synchronously. The first drive motor 15 provides power to the drive gear 19 and is the power source for the rotation of the entire scraper disc 12. The output shaft 14 connects the gear and the scraper disc 12, transmitting the rotational power of the gear to the scraper disc 12, which then rotates and cleans.

[0032] In this embodiment, after the device is started, the rotating frame 11 rotates at a certain angle, so that the scraper disc 12 on one side contacts the outer surface of the conveyor belt 3. Then, the first drive motor 15 connected to the scraper disc 12 on the side in contact with the outer surface of the conveyor belt 3 is started. The output end of the first drive motor 15 drives the active gear 19 in the corresponding snap-fit ​​plate 20 to rotate. When the active gear 19 rotates, it drives multiple driven gears 18 around it to rotate synchronously through the rack and pinion belt 17. When the active gear 19 and the driven gears 18 rotate synchronously, the output shaft 14 connected to its outer end also rotates synchronously. The output shaft 14 drives the scraper disc 12 at one end to rotate, thereby realizing the comprehensive and uniform scraping of residual materials on the outer surface of the conveyor belt 3 and improving the cleaning efficiency.

[0033] In this embodiment, the design of two adjacent snap-fit ​​plates 20 and multiple scraper discs 12 evenly distributed on two adjacent sides of the rotating frame 11 can increase the redundancy of the equipment. When one of them is damaged, the rotating frame 11 can be rotated directly to scrape the material through the scraper disc 12 on the other snap-fit ​​plate 20, thereby ensuring the continuous and normal operation of the conveying material. At the same time, they can be used alternately as needed.

[0034] In an optional embodiment of the present invention, the guide component 8 includes: The first lifting device 801 and the second lifting device 802 are respectively disposed on the belt conveyor base and located below the conveyor support structure 5. Both the first lifting device 801 and the second lifting device 802 are fixedly connected to the belt conveyor base. An active conveying roller 803 and a driven conveying roller 804 are disposed between the first lifting device 801 and the second lifting device 802, wherein the driven conveying roller 804 is located below the active conveying roller 803; The conveyor belt 3 passes between the active conveyor roller 803 and the driven conveyor roller 804, and the inner and outer surfaces of the conveyor belt 3 slide against the active conveyor roller 803 and the driven conveyor roller 804.

[0035] In a preferred embodiment, a driving device is installed at one end of the first lifting device 801. The driving device is rotatably connected to the active conveying roller 803. The driving device is used to drive the active conveying roller 803 to rotate. The rotation direction of the active conveying roller 803 is the same as that of the conveyor belt 3.

[0036] In this embodiment, there are two guide components 8, which are respectively disposed on both sides of the outer scraping component 1, located at the two ends of the first support rod 101 and the second support rod 102. The conveyor belt 3 passes through the two guide components 8 in sequence. The first lifting device 801 is fixedly installed on the first support rod 101, and the second lifting device 802 is fixedly disposed on the second support rod 102 relative to the first lifting device 801. Both the first lifting device 801 and the second lifting device 802 can be selected according to requirements, and a lifting rod with lifting function can be selected. There is a third preset distance between the active conveying roller 803 and the driven conveying roller 804. The third preset distance is set according to the thickness of the conveyor belt 3; the first lifting device 801 and the second lifting device 802 are respectively installed on the first support rod 101 and the second support rod 102 to support the active conveyor roller 803, the driven conveyor roller 804 and other components, and can also adjust the height to adapt to different operating states of the conveyor belt 3; the first lifting device 801 and the second lifting device 802 can be adjusted synchronously at the same time, or they can be adjusted separately, thereby adjusting the tilt angle of the conveyor belt 3, so that after the conveyor belt 3 deflects, the conveyor belt 3 can be reset by finely adjusting different height differences, thereby adjusting the deflection of the conveyor belt 3.

[0037] In this embodiment, the active conveying roller 803 and the driven conveying roller 804 are symmetrically arranged between the first lifting device 801 and the second lifting device 802 to clamp the conveyor belt 3. The active conveying roller 803 moves in the same direction as the conveyor belt 3 and can assist in driving the conveyor belt 3 to run. At the same time, it works with the driven conveying roller 804 to limit the belt and prevent the belt from running off-center. The driving device is installed inside the first lifting device 801 to provide rotational power to the active conveying roller 803 and drive the active conveying roller 803 to rotate. The conveyor belt 3 passes between the active conveying roller 803 and the driven conveying roller 804 and runs smoothly under the clamping and guiding action of the two.

[0038] In an optional embodiment of the present invention, the first lifting device 801 includes: A first lifting rod 8011 and a second lifting rod 8012 are provided on the first lifting rod 8011; The second lifting device 802 includes: A third lifting rod and a fourth lifting rod are disposed on the belt conveyor base opposite to the first lifting rod 8011; The driven conveying roller 804 is disposed between the first lifting rod 8011 and the third lifting rod; The active conveying roller 803 is disposed between the second lifting rod 8012 and the fourth lifting rod.

[0039] In this embodiment, the design of the first lifting rod 8011, the second lifting rod 8012, the third lifting rod, and the fourth lifting rod enables automatic adjustment of the distance between the driven conveyor roller 804 and the active conveyor roller 803, as well as adjustment of the overall height. The first lifting rod 8011 is used to adjust the overall height of the driven conveyor roller 804 and the active conveyor roller 803, while the second lifting rod 8012 can adjust the distance between the driven conveyor roller 804 and the active conveyor roller 803 by raising and lowering the height of the active conveyor roller 803, thereby adapting to conveyor belts 3 of different thicknesses and achieving tightening of the conveyor belt 3 after installation.

[0040] In this embodiment, during use, the heights of the second lifting rod 8012 and the fourth lifting rod can be adjusted according to the operating requirements of the conveyor belt 3. Then, according to the thickness requirements of the conveyor belt 3, the heights of the first lifting rod 8011 and the third lifting rod can be adjusted so that the active conveyor roller 803 and the driven conveyor roller 804 tightly clamp the conveyor belt 3. After the device is started, the drive device inside the first lifting device 801 is activated, driving the active conveyor roller 803 to rotate. The rotation direction of the active conveyor roller 803 is the same as the movement direction of the conveyor belt 3, assisting the conveyor belt 3 to run smoothly. The driven conveyor roller 804 is passively rotated under the drive of the conveyor belt 3, cooperating with the active conveyor roller 803 to limit and guide the conveyor belt 3, preventing the conveyor belt 3 from deviating during operation, ensuring that the conveyor belt 3 is always on the correct running trajectory, and providing stable conditions for subsequent scraping and cleaning operations.

[0041] In an optional embodiment of the present invention, the guide component 8 further includes: A horizontal plate 805 is fixedly installed between the first lifting device 801 and the second lifting device 802, and located below the driven conveying roller 804; A support arc plate 806 is fixedly installed on the horizontal plate 805. The support arc plate 806 has an elongated groove 807, and at least two spring telescopic rods 808 are provided in the elongated groove 807. A scraper 809 is installed at the upper end of the spring telescopic rod 808, and the scraper 809 abuts against the lower end of the driven conveying roller 804.

[0042] In this embodiment, the horizontal plate 805 is installed between the first lifting device 801 and the second lifting device 802 to fix and support the arc plate 806, providing an installation carrier for the arc plate 806. The horizontal plate 805 can be installed as needed. It can be installed on the base of the first lifting device 801 and the second lifting device 802 and not move up and down with the first lifting device 801 and the second lifting device 802. If it does not move up and down with the first lifting device 801 and the second lifting device 802, the upward movement adjustment of the first lifting device 801 and the second lifting device 802 is limited by the extension distance of the spring telescopic rod 808. Alternatively, it can be set on the lifting rod of the first lifting device 801 and the second lifting device 802 and move up and down with the first lifting device 801 and the second lifting device 802. The arc structure of the supporting arc plate 806 has the same surface curvature as the driven conveying roller 804, which facilitates close contact with the surface of the driven conveying roller 804. The length of the support plate 806 is the same as the length of the horizontal plate 805. The elongated groove 807 is opened along the length direction of the support plate 806 and is located at the center of the support plate 806. It is used to install the spring telescopic rod 808 and provides installation space for the spring telescopic rod 808. The length of the elongated groove 807 and the length of the scraper 809 can be set according to requirements and can be directly the same as the length of the support plate 806. The spring telescopic rod 808 has an elastic telescopic function and can automatically adjust its length according to the running state of the driven conveyor roller 804 to always provide appropriate pressure to the scraper 809. The number of spring telescopic rods 808 installed can be set according to requirements, with at least one at each end of the elongated groove 807. The scraper 809 contacts the lower end of the driven conveyor roller 804 and is used to scrape off the material residue attached to the surface of the driven conveyor roller 804 to avoid the material residue affecting the rotation of the driven conveyor roller 804 and the operation of the belt.

[0043] In this embodiment, during the overall operation, the first lifting device 801 and the second lifting device 802 drive the horizontal plate 805 and the supporting arc plate 806 to move synchronously; the spring telescopic rod 808 is installed in the long groove 807 of the supporting arc plate 806, and the scraper 809 at its upper end is in close contact with the lower surface of the driven conveyor roller 804. The spring telescopic rod 808 uses its own elasticity to keep the scraper 809 in close contact with the surface of the driven conveyor roller 804 at all times; when the driven conveyor roller 804 rotates, the scraper 809 continuously scrapes off the material residue attached to its surface, avoiding the accumulation of material residue on the surface of the driven conveyor roller 804, preventing the material from being carried into the space between the conveyor belt 3 and the roller body, causing belt wear or deviation, and further ensuring the stable operation of the entire belt conveyor and cleaning device.

[0044] In an optional embodiment of the present invention, the internal scraping assembly 6 includes: A positioning plate 601 is fixedly installed between two adjacent conveying support structures 5; Two extension plates 602 are symmetrically arranged at both ends of the positioning plate 601, and a third drive motor is provided in the extension plate 602. A cleaning roller 603 is disposed between the two extension plates 602 and rotatably connected to the two extension plates 602 via a third drive motor. The rotation direction of the cleaning roller 603 is opposite to the movement direction of the conveyor belt 3. The cleaning roller 603 is in contact with the inner surface of the conveyor belt 3.

[0045] In a preferred embodiment, the cleaning roller 603 is provided with a soft brush, which is in contact with the inner surface of the conveyor belt 3.

[0046] In this embodiment, a cleaning roller 603 is installed between the two extension plates 602. The rotation direction of the cleaning roller 603 is opposite to the movement direction of the conveyor belt 3. A third drive motor is installed inside any of the extension plates 602, and the output shaft of the third drive motor is connected to the cleaning roller 603 through a coupling. The positioning plate 601 is bolted between the two conveyor support structures 5 to fix and support the extension plates 602, providing an installation reference for the entire inner scraping assembly 6. The bolt connection facilitates disassembly and position adjustment. The extension plates 602 are symmetrically installed on the upper end of the positioning plate 601 to install the cleaning roller 603 and provide rotational support for the cleaning roller 603. The cleaning roller 603 contacts the inner surface of the conveyor belt 3 to scrape off residual material from the inner surface of the conveyor belt 3. Its rotation direction is opposite to the movement direction of the conveyor belt 3, which can enhance the scraping force and improve the cleaning effect. The third drive motor is installed inside the extension plate 602 to provide rotational power for the cleaning roller 603, driving the cleaning roller 603 to rotate.

[0047] In this embodiment, during overall operation, the inner scraping assembly 6 is fixed between the two conveying support structures 5 by bolts on the positioning plate 601. The position of the positioning plate 601 is adjusted so that the cleaning roller 603 fits tightly against the inner surface of the conveyor belt 3. When the device is working, the third drive motor inside the extension plate 602 starts, driving the cleaning roller 603 to rotate. Since the rotation direction of the cleaning roller 603 is opposite to the movement direction of the conveyor belt 3, relative motion is generated between the two. The cleaning roller 603 can efficiently scrape off the material residue attached to the inner surface of the conveyor belt 3. The positioning plate 601 and the extension plate 602 provide stable support for the cleaning roller 603 and the drive device throughout the process, ensuring that the inner scraping assembly 6 can continuously and stably complete the cleaning operation, and cooperate with the external scraping disc 12 to achieve comprehensive cleaning of the inner and outer surfaces of the belt.

[0048] The working process of the belt conveyor scraping and cleaning device of the present invention is as follows: First, check the connection of each component of the device to ensure that the support rod, side support plate, mounting plate 9, etc. are firmly connected, the snap-fit ​​plate 20 is snapped in place, the scraper disc 12, the cleaning roller 603 are in good contact with the conveyor belt 3, and each drive device and guide component 8 are operating normally without any loosening or jamming. After starting the device, the height is first adjusted by the first lifting device 801 and the second lifting device 802 so that the active conveying roller 803 and the driven conveying roller 804 tightly clamp the conveyor belt 3, ensuring that the conveyor belt 3 runs smoothly under the action of the guide component 8. Then, the drive device corresponding to the rotating frame 11 is started, and the angle of the rotating frame 11 is adjusted so that the scraper 12 is tightly attached to the outer surface of the conveyor belt 3. At the same time, the first drive motor 15 is started to drive the active gear 19, the driven gear 18 and the output shaft 14 to rotate, so that the scraper 12 rotates synchronously to clean the outer surface of the conveyor belt 3. Start the drive device of the inner scraping assembly 6 to drive the cleaning roller 603 to rotate. Utilize the opposite rotation direction of the cleaning roller 603 and the conveyor belt 3 to efficiently scrape off the residual material on the inner surface of the conveyor belt 3. During operation, the spring telescopic rod 808 drives the scraper 809 to adhere to the driven conveyor roller 804 to scrape off the residue on the roller surface in time, so as to avoid affecting the operation.

[0049] After the operation is completed, first turn off all drive devices. After all parts stop rotating, check the cleanliness of each part. Disassemble the snap-fit ​​plate 20 through the snap-fit ​​structure and clean and maintain the scraper disc 12, output shaft 14 and other parts to ensure normal use next time.

[0050] The belt conveyor scraping and cleaning device of the present invention forms a double-sided cleaning structure through the inner scraping component 6 and the outer scraping component 1, which can simultaneously clean the residual materials attached to the outer and inner surfaces of the conveyor belt 3, thoroughly remove the sticky materials attached to the top and bottom of the belt, completely avoid the problem of material residue accumulation, and significantly improve the overall cleanliness of the belt conveyor return section; the rotating frame 11 adopts a snap-fit ​​assembly structure with a cavity 16 and a snap-fit ​​plate 20, and the gear transmission component and the output shaft are integrated and installed on the snap-fit ​​plate, so that the components can be disassembled and repaired without disassembling the entire frame body; by matching the guide The design of component 8 allows for adaptive adjustment of the clamping state, reducing the difficulty of daily maintenance and disassembly, and effectively preventing the conveyor belt from running off-center, ensuring long-term stable operation of the equipment. At the same time, the guide component 8 has a spring telescopic rod 808 and a scraper 809 working together to continuously adhere to the surface of the driven conveyor roller 804 to clean the attached materials, preventing the roller from being squeezed and worn by the conveyor belt. Meanwhile, multiple scraper discs 12 achieve synchronous transmission through gear, rack and belt, resulting in uniform cleaning force, reducing local wear and operating load on the belt, and effectively extending the actual service life of the conveyor belt and roller accessories.
