[0024] As mentioned in the background technology, in the prior art, when the conveyor belt is cleaned after unloading materials at the unloading point, there is a problem that the materials are scattered everywhere accompanied by turbulent and violent airflow, and many highly viscous materials still cannot be cleaned up. The materials that often adhere to the conveyor belt enter the return channel again with the belt, thereby causing the problem of wear of the belt conveyor. For this reason, the present application proposes a material cleaner, which is provided with at least two hard cleaning mechanisms, and a spraying mechanism and an air drying mechanism are provided between at least two hard cleaning mechanisms. Such a configuration can scrape off the residual materials on the conveyor belt. And the hard cleaning mechanism has a guide slope on the side away from the conveyor belt, and the guide slope has a guide effect on the scraped materials, preventing the materials from flying around and entering the return conveyor belt. The material cleaner of the present application will be described in detail below in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 5As shown, the present application provides a material cleaner. The material cleaner is used at least to clean materials on a material conveying mechanism, and the material conveying mechanism includes a roller 20 and a conveyor belt 21 wound around the roller 20. The material cleaner includes a fixed frame 10, a hard cleaning mechanism 30, a spraying mechanism 40 and an air drying mechanism 50.

[0026] Specifically, the fixed frame 10 is arranged on the outer peripheral side of the drum 20; the hard cleaning mechanism 30 includes at least two, at least two hard cleaning mechanisms 30 are arranged at intervals along the height direction of the fixed frame 10, and there is a first gap 60 between two adjacent hard cleaning mechanisms 30, each hard cleaning mechanism 30 includes a scraper 33 and a connecting assembly 34, the scraper 33 is used to be arranged against the conveyor belt 21, and the side of the scraper 33 away from the conveyor belt 21 has a guide slope 331, the connecting assembly 34 is connected to the fixed frame 10, and the scraper 33 and the connecting assembly 34 are detachably connected; the spraying mechanism 40 is fixed to the fixed frame 10 and is located in the first gap 60, so as to at least be used to spray liquid onto the conveyor belt 21; the air-drying mechanism 50 is fixed below the spraying mechanism 40 and is located in the first gap 60, so as to at least be used to air-dry the material on the surface of the conveyor belt 21.

[0027] In the present application, a material sweeper is arranged near a roller 20 around which a conveyor belt 21 is wound, and the material sweeper is used to sweep the residual material on the conveyor belt 21. Specifically, a fixed frame 10 on the material sweeper is arranged on the outer peripheral side of the roller 20, and at least two hard sweeping mechanisms 30 are arranged at intervals along the height direction of the fixed frame 10. Each hard sweeping mechanism 30 includes a scraper 33 and a connecting assembly 34. The scraper 33 is used to be arranged close to the conveyor belt 21 and is used to scrape the residual material on the conveyor belt 21. There is a guide slope 331 on the side of the scraper 33 away from the conveyor belt 21. The guide slope 331 can effectively guide the material to fly and form a route, and prevent the material from entering the conveyor belt 21 on the return journey, resulting in the conveyor belt 21 not being cleaned cleanly. In the present application, the connecting assembly 34 is connected to the fixed frame 10, and the scraper 33 is detachably connected to the connecting assembly 34, which is convenient for replacing the scraper 33. There is a first gap 60 between two adjacent hard cleaning mechanisms 30, and a spray mechanism 40 and an air drying mechanism 50 disposed below the spray mechanism 40 are disposed in the first gap 60. The spray mechanism 40 and the air drying mechanism 50 are both fixed on the fixing frame 10, so that the relatively viscous materials remaining on the conveyor belt 21 can be further scraped off. The spray mechanism 40 is at least used to spray liquid onto the conveyor belt 21, and the air drying mechanism 50 is at least used to air dry the materials on the surface of the conveyor belt 21.

[0028] In actual operation, the material on the conveyor belt 21 is first scraped by the hard cleaning mechanism 30 located at the top, which can scrape off most of the residual material, and the scraped material can enter the material collection device arranged below the material cleaner along the guide slope 331, reducing the scattering of the material and preventing the material from entering the return conveyor belt 21. As the roller 20 rotates, the residual material on the conveyor belt 21 is scraped off, and the material remaining on its surface is the material with strong viscosity. The second spray mechanism 40 is used to spray softened water to soften the material with strong viscosity on the conveyor belt 21, and then the third air-drying mechanism 50 is used to air-dry the material on the conveyor belt 21 after spraying. Such a configuration is conducive to the subsequent hard cleaning mechanism 30 to scrape off the material. As the conveyor belt 21 moves (i.e. Figure 1 ), the fourth hard cleaning mechanism 30 arranged below the air drying mechanism 50 scrapes the material on the conveyor belt 21 again, and the residual material on the conveyor belt 21 can be further scraped clean, and the scraped material also enters the material collection device along the guide slope 331 on the scraper 33, further reducing the material flying around. That is to say, the material cleaner provided by the present application is provided with a hard cleaning mechanism 30, a spray mechanism 40, an air drying mechanism 50 and a hard cleaning mechanism 30 in sequence from top to bottom along the height direction of the fixed frame 10, and a guide slope 331 is provided on each hard cleaning mechanism 30. Through the joint action of the four mechanisms, the residual material on the conveyor belt 21 can be effectively cleaned.

[0029] Furthermore, in this embodiment, a nozzle (not shown in the figure) is provided on the spray mechanism 40, which can spray softened water onto the conveyor belt 21 and soften the residual material on the conveyor belt 21, which is conducive to the hard cleaning mechanism 30 provided under the air-drying mechanism 50 to further scrape off the residual material. In this way, the residual material on the conveyor belt 21 can be cleaned up, the adverse effect of the residual material on the conveyor belt 21 can be reduced, and the service life of the equipment can be extended. The spray mechanism 40 also includes a pipeline system (not shown in the figure), which is used to transport water to each nozzle. During actual installation, the design of the pipeline needs to consider the stability of the water flow and the pressure distribution.

[0030] Furthermore, in the present embodiment, the air-drying mechanism 50 includes an air knife (not shown in the figure), and the air-drying mechanism 50 is used to air-dry the material on the conveyor belt 21 after spraying, which is conducive to the hard cleaning mechanism 30 arranged below the air-drying mechanism 50 to further scrape off the residual material. In this way, under the joint action of the spraying mechanism 40 and the air-drying mechanism 50, the residual material on the conveyor belt 21 can be cleaned up, reducing the adverse effects of the residual material on the conveyor belt 21 and extending the service life of the equipment. In the present embodiment, the air knife can effectively and quickly remove the residual moisture or other liquids on the conveyor belt 21 to ensure that the surface is dry, which is conducive to preventing material adhesion and avoiding affecting the subsequent scraping process. In addition, the air-drying mechanism 50 can also reduce the residue of fine particles or light residues on the conveyor belt 21.

[0031] When actually installing the spray mechanism 40 and the air-drying mechanism 50, it is necessary to pay attention to adjusting the angle between the two and the conveyor belt 21. A suitable tilt angle can make the spray water flow more effectively impact the surface of the conveyor belt 21, enhance the flushing angle of the adherends, thereby improving the cleaning efficiency, reducing the wear on the equipment, and extending the service life of the material sweeper. A suitable tilt angle helps to optimize the air-drying effect, so that the airflow of the air-drying mechanism 50 blows to the surface of the conveyor belt 21 at a more effective angle, accelerating the evaporation of water; and a suitable angle can also ensure that the airflow evenly covers the entire width of the conveyor belt 21 to avoid uneven drying; a suitable tilt angle can reduce the energy consumption required by the air-drying mechanism 50, etc.

[0032] like Figures 1 to 3As shown, the hard cleaning mechanism 30 includes a first hard cleaning mechanism 31 and a second hard cleaning mechanism 32, and the first hard cleaning mechanism 31 is located above the second hard cleaning mechanism 32. The first hard cleaning mechanism 31 and the second hard cleaning mechanism 32 are provided to realize multiple cleaning of the conveyor belt 21, and the residual materials on the conveyor belt 21 can be scraped off. Specifically, the scraper 33 of the first hard cleaning mechanism 31 is provided with a first cutting edge 311, and the scraper 33 has a first arc surface 312 facing the drum 20 and connected to the first cutting edge 311, the center of the first arc surface 312 is located between the first arc surface 312 and the drum 20, and the guide slope 331 on the scraper 33 has a second arc surface 313 and a third arc surface 314 arranged in sequence from the top to the bottom of the fixed frame 10 and connected to each other, the center of the second arc surface 313 is located between the second arc surface 313 and the drum 20, and the center of the third arc surface 314 is located on the side of the scraper 33 away from the drum 20. In other words, the scraper 33 of the first hard cleaning mechanism 31 is configured to match the shape of the drum 20, which can ensure that the first cutting edge 311 can closely fit the conveyor belt 21 on the surface of the drum 20 and effectively scrape off most of the materials attached to the conveyor belt 21. In addition, the centers of the first arc surface 312 and the second arc surface 313 are both located between the roller 20 and the arc surface. Such a configuration can increase the stress strength and wear resistance of the first cutting edge 311, and the scraper 33 is not easily damaged when scraping the material on the conveyor belt 21; it can also enable the scraper 33 to better fit the roller 20 or the conveyor belt 21, provide stronger pressure, and thus more effectively scrape the material attached to the conveyor belt 21, which helps to maintain the optimal performance of the conveyor belt 21 and reduce the maintenance frequency; it can also enable the scraper 33 to have better structural stability, ensuring that the scraper 33 maintains a good contact surface and a stable working state throughout its service life, thereby helping to extend the service life of the material sweeper. The center of the third arc surface 314 is located on one side of the scraper 33 back roller 20, and the second arc surface 313 and the third arc surface 314 are connected to each other, and the centers of the second arc surface 313 and the third arc surface 314 are in opposite positions. When the scraper 33 is working, the material scraped from the conveyor belt 21 can enter the material collecting device along with the second arc surface 313 and the third arc surface 314, and is not easy to fly around. It also avoids the scraped material from entering the return conveyor belt 21, thereby improving the collection efficiency of the scraped material and reducing pollution to the environment.

[0033] Furthermore, the scraper 33 of the second hard cleaning mechanism 32 is provided with a second cutting edge 321, and the scraper 33 has a fourth arc surface 322 connected to the second cutting edge 321 facing away from the drum 20, the center of the fourth arc surface 322 is located on the side of the scraper 33 away from the drum 20, and the guide slope 331 on the scraper 33 has a fifth arc surface 323, the center of the fifth arc surface 323 is located on the side of the scraper 33 away from the drum 20. In other words, the scraper 33 on the second hard cleaning mechanism 32 is arranged in the opposite direction to the scraper 33 on the first hard cleaning mechanism 31. With such an arrangement, after the first scraping, spraying and air drying, the second hard cleaning mechanism 32 performs a second cleaning of the conveyor belt 21 from the opposite direction of the conveyor belt 21, which can ensure that the residual materials with high adhesion and viscosity on the conveyor belt 21 can be completely removed, so that the residual materials on the conveyor belt 21 are cleaned. In addition, such a configuration is also conducive to removing tiny particles that are redeposited on the surface of the conveyor belt 21 due to air flow during the air drying process. In this embodiment, the center of the fourth arc surface 322 and the center of the fifth arc surface 323 connected to the second cutting edge 321 of the scraper 33 of the second hard cleaning mechanism 32 are both located on the side of the scraper 33 away from the drum 20. Such a configuration is conducive to increasing the thickness of the second cutting edge 321, ensuring the structural stability of the second hard cleaning mechanism 32 and reducing the maintenance frequency, etc., and is conducive to increasing the pressure when the second cutting edge 321 is attached to the conveyor belt 21, improving the working efficiency of the material cleaner, and cleaning the materials on the conveyor belt 21. The guide slope 331 of the scraper 33 in the second hard cleaning mechanism 32 is different in shape from the guide slope 331 of the scraper 33 in the first hard cleaning mechanism 31. This arrangement is mainly based on the working process of each hard cleaning mechanism 30 to design the guide slope 331 on the scraper 33 accordingly, which can help the scraper 33 collect the scraped material when working and reduce the scattering of material.

[0034] That is to say, in this embodiment, two types of scrapers 33 are provided, and through the joint action of the two types of scrapers 33, it is possible to ensure that the residual materials on the conveyor belt 21 are cleaned. In addition, the thickness of the blade edge of the two types of scrapers 33 is ensured during design, which can extend the service life of the hard cleaning mechanism 30 and reduce the replacement frequency of the scraper 33.

[0035] like Figures 1 to 5As shown, the connection assembly 34 includes a connection pipe 341 and a connection component 342. Specifically, the connection pipe 341 and the connection component 342 both extend in a direction parallel to the axis of the roller 20, and the connection pipe 341 is connected to the fixing frame 10. Such a configuration is conducive to the installation of the scraper 33. Among them, the connection component 342 is at least partially arranged in the connection pipe 341, and a notch 3411 is arranged on the connection pipe 341. The connection component 342 is partially penetrated through the notch 3411 and connected to the scraper 33 by a buckle. In this embodiment, the connection component 342 is arranged in the connection pipe 341, which protects the connection component 342, reduces wear and tear, and can extend the service life of the connection component 342; and the connection pipe 341 provides a solid and stable shell for the connection component 342, which can enhance the rigidity of the structure and reduce the displacement of the scraper 33 during operation, so that the conveyor belt 21 can be cleaned. That is to say, in the present application, the connection component 342 is arranged in the connection tube 341, which can enhance the durability and reliability of the material sweeper, improve operational safety and optimize space utilization efficiency. The connection component 342 is partially passed through the notch 3411, and the connection tube 341 can effectively support the connection component 342, which is conducive to the installation of the scraper 33 and ensures stability during work. The connection component 342 and the scraper 33 are connected by a snap-fit ​​connection, so that the scraper 33 can be quickly installed and replaced, reducing maintenance time and improving work efficiency. The snap-fit ​​connection can ensure the correct installation position of the scraper 33 and avoid problems such as poor cleaning effect or equipment damage due to improper installation; a good snap-fit ​​connection can provide a stable connection to prevent the scraper 33 from shifting during work, thereby maintaining a stable cleaning effect. Compared with the method of using fasteners such as screws and nuts, the snap-fit ​​connection enhances the safety and stability of the system.

[0036] Furthermore, the connecting member 342 includes a connecting plate 3421, a lifting plate 3422, a bottom plate 3423 and a telescopic member 35. The connecting plate 3421 and the lifting plate 3422 are integrally formed, and the connecting plate 3421 is inserted into the notch 3411 and connected to the scraper 33. In this embodiment, the connecting plate 3421 and the lifting plate 3422 are integrally formed to enhance the support performance of the scraper 33. In this embodiment, a notch 3411 is provided on the connecting pipe 341, and the connecting plate 3421 is inserted from the notch 3411, so that the operator can install and adjust the position of the scraper 33 without dismantling the overall device; in addition, the connecting plate 3421 is inserted from the notch 3411, which is also conducive to increasing the flexibility of the scraper 33, and the contact with the surface of the conveyor belt 21 can be adjusted within a certain range through the connecting plate 3421, thereby ensuring the cleaning effect. In this embodiment, the bottom plate 3423 is arranged in the connecting tube 341 and fixedly connected to the lifting plate 3422 through the telescopic component 35, thereby enhancing the structural stability. In this embodiment, the telescopic component 35 is telescopic relative to the fixing frame 10 to adjust the height of the connecting plate 3421 protruding from the outer surface of the connecting tube 341. When the scraper 33 needs to be replaced, the telescopic component 35 is loosened to separate the bottom plate 3423 from the lifting plate 3422, and the connecting plate 3421 integrally formed with the lifting plate 3422 will increase the height protruding from the outer surface of the connecting tube 341, which is conducive to replacing the scraper 33. After the replacement is completed, the bottom plate 3423 is connected and fixed to the lifting plate 3422 by the telescopic component 35, which is conducive to the scraper 33 working again.

[0037] like Figure 4 and Figure 5 As shown, one of the scraper 33 and the connecting plate 3421 is provided with a slot 36, and the other is provided with a hook 37 adapted to the slot 36. For example, the slot 36 can be provided on the scraper 33, and the hook 37 can be provided on the connecting plate 3421; or the slot 36 can be provided on the connecting plate 3421, and the hook 37 can be provided on the scraper 33. Figure 4 and Figure 53 shows that the slot 36 is arranged on the scraper 33 and the hook 37 is arranged on the connecting plate 3421. By using the slot 36 and the hook 37 in combination, the correct installation position of the scraper 33 can be ensured to avoid the problem of poor cleaning effect or equipment damage caused by improper installation; it can also provide a stable connection to prevent the scraper 33 from shifting during operation, thereby maintaining a stable cleaning effect. Compared with the method of using fasteners such as screws and nuts 352, the slot 36 and the hook 37 are used to form a snap connection, which enhances the safety and stability of the system. In this embodiment, the telescopic component 35 includes an adjusting bolt 351 and a nut 352. One end of the adjusting bolt 351 is inserted through the connecting pipe 341, the bottom plate 3423 and the lifting plate 3422 and can be telescopic relative to the connecting pipe 341 to adjust the height of the connecting plate 3421 protruding from the outer surface of the connecting pipe 341. The other end of the adjusting bolt 351 is fixed to the connecting pipe 341 by the nut 352. With such a configuration, the angle and pressure between the scraper 33 and the conveyor belt 21 can be precisely adjusted, which helps to scrape away the residual materials on the conveyor belt 21; when the scraper 33 is worn and needs to be replaced or adjusted, the use of the adjusting bolt 351 and the nut 352 can simplify the operation and facilitate replacement and maintenance. In addition, when facing conveyor belts 21 of different thicknesses or rollers 20 of different diameters, the position of the scraper 33 can be quickly and accurately adjusted by using the adjusting bolt 351 and the nut 352, which increases the versatility and adaptability of the equipment; correctly adjusting the adjusting bolt 351 and the nut 352 can provide a stable supporting force, ensuring that the scraper 33 remains stable during operation, and avoiding problems such as incomplete cleaning or equipment damage caused by looseness.

[0038] like Figure 1As shown, the fixing frame 10 includes a first fixing portion 11, a second fixing portion 12 and an adjusting assembly 13, and the hard cleaning mechanism 30, the spraying mechanism 40 and the air drying mechanism 50 are all arranged between the first fixing portion 11 and the second fixing portion 12. In this embodiment, the adjusting assembly 13 can be connected between the hard cleaning mechanism 30 and the first fixing portion 11 to adjust the distance between the first fixing portion 11 and the second fixing portion 12; the adjusting assembly 13 can also be connected between the hard cleaning mechanism 30 and the second fixing portion 12 to adjust the distance between the first fixing portion 11 and the second fixing portion 12; the adjusting assembly 13 can also be connected between the hard cleaning mechanism 30 and the first fixing portion 11 and the second fixing portion 12 at the same time to adjust the distance between the first fixing portion 11 and the second fixing portion 12. In actual work, a sliding track (not shown in the figure) and a locking device (such as a locking bolt, a clamp, etc.) (not shown in the figure) can be set on the fixing frame 10, and the material sweeper can be locked after the length of the fixed position is adjusted. In addition, an adjustable connector (not shown in the figure) can be provided between the fixing frame 10 and the hard cleaning mechanism 30 to adjust the length of the fixed position of the material cleaner. In this way, the material cleaner can adapt to conveyor belts 21 of different widths; the spacing between the first fixing portion 11 and the second fixing portion 12 of the fixing frame 10 can also be adjusted according to the specific width and layout of the conveyor belt 21, which can ensure that the scraper 33 and the conveyor belt 21 maintain an optimal contact area, improve the cleaning effect, reduce the damage of residual materials to the conveyor belt 21 and the roller 20, and extend their service life. If the spacing between the fixing frames 10 is too large or too small, the scraper 33 may not completely cover the surface of the conveyor belt 21, or cause local excessive pressure, accelerate the wear of the scraper 33 and other components, and improve operational safety and reduce maintenance costs.

[0039] In this embodiment, the adjustment component 13 includes a screw 131 and a sleeve 132, one end of the screw 131 is screwed to the hard cleaning mechanism 30, and the other end of the screw 131 is connected to the sleeve 132 by a thread. In this way, the screw 131 can be freely extended and retracted in the sleeve 132, thereby automatically compensating for the change in the length of the scraper 33, ensuring that the scraper 33 always maintains an appropriate contact pressure and angle with the conveyor belt 21, and maintaining an efficient cleaning effect to clean the residual materials on the conveyor belt 21. Setting the screw 131 in the sleeve 132 can provide additional support, reduce the position deviation of the scraper 33 caused by external impact or vibration, improve the stability and reliability of the system, and extend the service life of the equipment. In addition, the adaptability of the material sweeper to various application scenarios is enhanced, and the maintenance process is simplified. In this embodiment, the screw 131 and the sleeve 132 are connected by a thread (i.e., a screw thread), allowing the operator to accurately control the contact pressure and angle of the scraper 33 by rotating the position of the screw 131, thereby improving the cleaning effect. In addition, the threaded connection is a strong connection method that can effectively prevent the screw 131 from accidentally moving or loosening during use, thereby enhancing the stability and reliability of the structure. The threaded connection is also easy to install and maintain the screw 131, and is conducive to the replacement and maintenance of the scraper 33. In this embodiment, the sleeve 132 can be fixedly arranged on the first fixing portion 11, can also be fixedly arranged on the second fixing portion 12, and can also be fixedly arranged on the first fixing portion 11 and the second fixing portion 12 at the same time. Figure 2 The embodiment shows that the sleeve 132 is fixedly arranged on the first fixing portion 11 and the second fixing portion 12 at the same time. In this way, the screw 131 moves along the axial direction of the sleeve 132 to adjust the distance between the first fixing portion 11 and the second fixing portion 12, thereby improving the accuracy of adjusting the distance between the first fixing portion 11 and the second fixing portion 12. In addition, in this embodiment, the sleeve 132 is fixed to the fixing frame 10 by welding, thereby improving the structural stability.

[0040] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a threaded hole 70 is formed between the bottom plate 3423 and the lifting plate 3422 on the same hard cleaning mechanism 30, and one end of the screw rod 131 close to the connecting part 342 is screwed to the threaded hole 70. The threaded hole 70 and the screw rod 131 are used in conjunction with each other to achieve precise adjustment of the position of the scraper 33 to achieve the best cleaning effect. The special threaded hole 70 can be set to quickly install and remove the screw rod 131, simplifying the installation and maintenance process.

[0041] like Figures 1 to 5As shown, the material sweeper also includes a tensioning mechanism 80, which is arranged on the fixed frame 10, and the tensioning mechanism 80 is used to adjust the magnitude of the resistance force applied by the scraper 33 to the conveyor belt 21. In this embodiment, the tensioning mechanism 80 is an automatic tensioning adjustment structure, which is mainly used to ensure that a constant resistance pressure is maintained between the scraper 33 and the conveyor belt 21 on the roller 20, which helps to maintain an efficient cleaning effect. As the hard cleaning mechanism 30 is used for a longer time, the scraper 33 wears, resulting in a decrease in the pressure of the scraper 33 on the roller 20 or the conveyor belt 21, which affects the cleaning effect. The tensioning mechanism 80 can automatically compensate for the difference caused by such wear and tear, ensuring that the scraper 33 always fits the surface with appropriate force, thereby maintaining a stable cleaning effect and extending the service life of the scraper 33. And because the automatic tensioning adjustment mechanism can adapt to the wear of the scraper 33 and make corresponding adjustments, the need for manual inspection and adjustment is reduced, the maintenance frequency and workload are reduced, and the risk of equipment failure or accidents caused by improper manual adjustment is reduced, thereby improving the operating safety of the entire system.

[0042] Furthermore, the tensioning mechanism 80 includes a spring 81, a connecting piece 82, a support rod 83, a connecting member 84 and a locking nut 85. In this embodiment, the connecting piece 82 is protrudingly arranged on the outer surface of the sleeve 132, and an avoidance hole 841 is arranged on the connecting piece 82. The support rod 83 is fixedly arranged on the fixing frame 10, and the connecting member 84 is rotatably sleeved on the support rod 83 and penetrated through the avoidance hole 841. The connecting member 84 is sleeved with a spring 81 and a locking nut 85, and the two ends of the spring 81 are respectively pressed against the locking nut 85 and the connecting piece 82, and the locking nut 85 is located on the side of the connecting piece 82 away from the support rod 83, so that an automatic tensioning adjustment mechanism is formed. When the scraper 33 on the hard cleaning mechanism 30 is worn, the tensioning mechanism 80 is fixedly connected to the fixed frame 10. When the scraper 33 is moved away from the conveyor belt 21 by the friction and thrust of the conveyor belt 21, the tensioning mechanism 80 automatically adjusts the tensioning force, thereby causing the sleeve 132 and the screw 131 to expand and contract axially to control the force-bearing area between the scraper 33 and the conveyor belt 21 to maintain a constant push force. Among them, the spring 81 is the core part of the tensioning mechanism 80. The spring 81 can provide continuous tensioning force to offset the wear of the scraper 33 over time. The spring 81 will automatically expand and contract according to the degree of wear of the scraper 33 to ensure constant pressure. In this embodiment, the spring 81 is set on the connecting member 84 and is provided with a locking nut 85 to assist in adjusting the tensioning force. Of course, in other embodiments of the present application, the tensioning mechanism 80 may be equipped with sensors and other equipment for wear detection, so as to monitor the state of the scraper 33 in real time and set a feedback mechanism for automatic adjustment, etc. Other deformation methods under the present application are all within the protection scope of the present application.
