[0024] like Figure 1-6As shown, a conveyor belt cleaning device is provided. A roller-type cleaning brush 2 is provided below the conveyor belt 1. A drive motor 7 is provided on one side of the conveyor belt 1. The drive motor 7 is connected to one end of the cleaning brush 2. Fixed frames are provided on both sides of the conveyor belt 1. The other end of the drive motor 7 and the cleaning brush 2 are set between the two fixed frames. The other end of the drive motor 7 and the cleaning brush 2 are slidably and elastically connected to the fixed frames.

[0025] The fixed frame includes a first fixed frame 4 and a second fixed frame 11. The first fixed frame 4 and the second fixed frame 11 are set on the frame on both sides of the conveyor belt 1. The drive motor 7 is set on the first fixed frame 4, and the other end of the cleaning brush 2 is set on the second fixed frame 11.

[0026] When the conveyor belt 1 is running, the drive motor 7 is started, and the drive motor 7 and the conveyor belt 1 are interlocked to start and stop. The motor drives the roller cleaning brush 2 to rotate, so that the nylon roller brush contacts the surface of the conveyor belt 1 and generates a reverse force, thereby sweeping off the wet material and dust attached to the reverse surface of the belt. The swept material falls into the discharge port ash bin 3 below. At the same time, since the drive motor 7 and the other end of the cleaning brush 2 are slidably elastically connected to the fixed frame, the roller brush is always lightly in contact with the belt surface under the action of the spring, ensuring the cleaning effect. The entire device is installed on the frame on both sides of the conveyor belt 1 by the first fixed frame 4 and the second fixed frame 11, respectively, to achieve stable support and adjustment functions.

[0027] In the preferred embodiment, the lower surface of the first fixing frame 4 is connected to the first mounting base 5 of the U-shaped structure. The inner side of the first mounting base 5 is provided with a sliding groove. The two sides of the first mounting plate 6 are slidably connected to the sliding groove on the inner side of the first mounting base 5. The drive motor 7 is mounted on the first mounting plate 6. The lower surface of the first mounting plate 6 is provided with a plurality of first guide posts 9. The plurality of first guide posts 9 are slidably connected to the first base plate 8 at the bottom of the first mounting base 5. A plurality of first springs 10 are provided between the first base plate 8 and the first mounting plate 6. The drive roller-type cleaning brush 2 rotates, causing it to contact the lower surface of the conveyor belt 1 and generate a reverse rotational force, thereby removing wet material and dust from the reverse surface of the belt. The cleaned material falls into the ash hopper 3 at the discharge port below. During this process, the first mounting plate 6 is slidably connected to the inner sliding groove of the first mounting base 5 on both sides to achieve a lateral guiding function. At the same time, multiple first guide posts 9 slide up and down along the first base plate 8 to provide vertical guidance for the cleaning brush 2. The first spring 10 is set between the first base plate 8 and the first mounting plate 6. Through the spring force, it abuts against the first mounting plate 6, thereby driving the cleaning brush 2 to always lightly adhere to the lower surface of the conveyor belt 1, realizing the function of adaptive adjustment of the contact force.

[0028] This structure provides elastic support through the first spring 10, enabling the roller-type sweeping brush 2 to automatically adjust the contact pressure according to the belt running status, avoiding poor contact caused by belt misalignment or thickness changes, and improving sweeping efficiency and stability. At the same time, the sliding connection between the first mounting plate 6 and the first mounting base 5, combined with the sliding structure between the guide column and the base plate, ensures the stability and guiding accuracy of the device during operation. The overall structure is compact and easy to adjust, improving the equipment's adaptability to complex working conditions, effectively reducing the frequency of manual maintenance, ensuring a clean on-site environment, and reducing labor intensity.

[0029] In the preferred embodiment, the first spring 10 is sleeved on the first guide post 9, the lower end of the first spring 10 abuts against the first base plate 8, the first mounting plate 6 is provided with a first limiting block 601 at the root of the first guide post 9, and the upper end of the first spring 10 abuts against the surface of the first limiting block 601.

[0030] The first spring 10 is sleeved on the first guide post 9, with its lower end abutting against the first base plate 8 and its upper end abutting against the surface of the first limiting block 601. The spring force pushes the first mounting plate 6 upward, so that the cleaning brush 2 always adheres to the lower surface of the conveyor belt 1. When the belt running state changes, the first limiting block 601 can restrict the position of the first spring 10 to ensure stable transmission of elastic force.

[0031] The first spring 10 is sleeved on the first guide post 9, and the upper end of the spring is positioned by the first limiting block 601, making the spring force more uniform and the structure more compact, thus improving the overall stability and guiding accuracy. The setting of the first spring 10 not only ensures that the roller cleaning brush 2 always lightly contacts the surface of the conveyor belt 1, but also realizes the adaptive adjustment function, which can effectively cope with complex working conditions such as belt deviation and vibration during operation, improving cleaning efficiency and device reliability. At the same time, the design of the limiting block enhances the load-bearing capacity and safety of the structure, reduces the maintenance frequency, and extends the service life of the equipment.

[0032] In the preferred embodiment, the first mounting plate 6 is provided with multiple oblong holes, and the drive motor 7 is mounted on the oblong holes by multiple double-headed bolts. The top of the first mounting plate 6 is provided with a protruding first ear plate 602, and the first ear plate 602 is provided with multiple first adjusting bolts 603. The first adjusting bolts 603 pass through the first ear plate 602 and are threadedly connected to the drive motor 7.

[0033] During installation or commissioning, the drive motor 7 is fixed to the oblong hole of the first mounting plate 6 by multiple double-headed bolts. After loosening or tightening the double-headed bolts, the horizontal position of the drive motor 7 can be adjusted along the direction of the oblong hole. At the same time, by rotating the first adjusting bolt 603 on the first ear plate 602, the drive motor 7 can be pushed or pulled back to achieve the vertical height adjustment of the drive motor 7, thereby ensuring that the roller cleaning brush 2 and the lower surface of the conveyor belt 1 maintain a good fit and meet the cleaning needs under different working conditions.

[0034] The structure, through the design of the waist-shaped hole, double-headed bolt, and first adjusting bolt 603, allows the drive motor 7 to be flexibly adjusted in both horizontal and vertical directions, improving the adaptability and installation accuracy of the device. It not only facilitates on-site debugging and subsequent maintenance, but also effectively ensures stable contact between the roller-type sweeping brush 2 and the conveyor belt 1, improving sweeping efficiency. The overall structure is simple and practical, easy to adjust, and enhances the reliability of equipment operation and the convenience of maintenance.

[0035] In the preferred embodiment, a second mounting base 12 with a U-shaped structure is provided below the second fixed frame 11. A sliding groove is provided on the inner side of the second mounting base 12. The second mounting plate 13 is slidably connected to the sliding groove. The shaft at the other end of the cleaning brush 2 is rotatably connected to the rotating seat 14. The rotating seat 14 is set on the second mounting plate 13. A plurality of second guide posts 16 are provided at the lower end of the second mounting plate 13. The second guide posts 16 pass through the second base plate 1201 at the bottom of the second mounting base 12 and are slidably connected to the second base plate 1201. A plurality of springs are provided between the second base plate 1201 and the second mounting plate 13.

[0036] The second spring 15 is sleeved on the second guide post 16, and the lower end of the second spring 15 abuts against the second base plate 1201. The second mounting plate 13 is provided with a second limiting block 1301 at the root of the second guide post 16, and the upper end of the second spring 15 abuts against the surface of the second limiting block 1301.

[0037] The other end of the cleaning brush 2 is rotatably connected to the rotating seat 14 via a shaft and is installed in the second mounting plate 13 on the second fixed frame 11. The second mounting plate 13 is slidably connected to the inner sliding groove of the U-shaped second mounting seat 12 to achieve guidance. The lower end of the second mounting plate 13 is provided with multiple second guide posts 16, which pass through the second base plate 1201 at the bottom of the second mounting seat 12 and slide with it. Multiple second springs 15 are sleeved on the second guide posts 16, with the lower end abutting against the second base plate 1201 and the upper end abutting against the surface of the second limiting block 1301. The limiting block is located at the root of the second guide post 16. Through the elastic force of the second springs 15, the other end of the cleaning brush 2 is always lightly attached to the bottom of the conveyor belt 1 to achieve an adaptive up and down floating function. During the belt operation, the height of the cleaning brush is automatically adjusted to ensure stable contact and complete the cleaning operation on the reverse side of the belt.

[0038] This structure, through the design of the second spring 15 in conjunction with the second guide post 16 and the limiting block 1301, enables the other end of the cleaning brush 2 to have good elastic support and guiding performance, effectively adapting to changes such as vibration and offset during the operation of the conveyor belt 1, and maintaining a stable fit. At the same time, the sliding connection between the second mounting plate 13 and the second mounting base 12 further enhances the guiding accuracy and running stability of the structure. The overall design is reasonable and flexible, which not only improves cleaning efficiency but also extends the service life of the equipment, reduces the frequency of manual maintenance, and ensures the cleanliness of the site environment.

[0039] In the preferred embodiment, the second mounting plate 13 is also provided with multiple waist-shaped holes, and the rotating seat 14 is installed on the waist-shaped holes by multiple double-headed bolts. The top of the second mounting plate 13 is provided with a protruding second ear plate 1302, and the second ear plate 1302 is provided with multiple second adjusting bolts 1303. The second adjusting bolts 1303 pass through the second ear plate 1302 and are threadedly connected to the rotating seat 14.

[0040] The shaft at the other end of the cleaning brush 2 is connected to the oblong hole on the second mounting plate 13 via the rotating seat 14. The rotating seat 14 is fixed to the oblong hole by multiple double-headed bolts. After loosening or tightening the bolts, it can be adjusted horizontally along the direction of the oblong hole. At the same time, the top of the second mounting plate 13 is provided with a protruding second ear plate 1302, on which multiple second adjusting bolts 1303 are provided. The bolts pass through the second ear plate 1302 and are threadedly connected to the rotating seat 14. By rotating the second adjusting bolts 1303, the position of the rotating seat 14 and the end of the cleaning brush 2 can be adjusted in the vertical direction, thereby ensuring that the cleaning brush 2 as a whole maintains good contact with the lower surface of the conveyor belt 1 and meets the cleaning needs under different operating conditions.

[0041] This structure, through the design of the waist-shaped hole, double-headed bolt, and second adjusting bolt 1303, allows the other end of the cleaning brush 2 to be flexibly adjusted in both horizontal and vertical directions, realizing the function of synchronous adjustment with the drive motor 7. This ensures that the entire cleaning brush is evenly attached to the lower surface of the conveyor belt 1. It not only improves the adaptability of the device to different working conditions, but also enhances the cleaning efficiency and operational stability. The structure is simple, easy to operate, and convenient for on-site debugging and subsequent maintenance, thus improving the overall performance and practicality of the equipment.

[0042] In the preferred embodiment, the drive motor 7 is connected to the first mounting plate 6 via a gearbox, which is a worm gearbox.

[0043] Below the cleaning brush 2, there is also a dust collection bin 3.

[0044] The drive motor 7 is connected to the cleaning brush 2 via a worm gear box and is fixed on the first mounting plate 6. After the drive motor 7 is started, the power is transmitted to the cleaning brush 2 after being reduced and increased in torque by the worm gear box, causing it to rotate and contact the lower surface of the conveyor belt 1 and act in the opposite direction to remove the attached wet material and dust. The swept material falls into the dust collection bin 3 set below the cleaning brush 2, is collected and then conveyed to the discharge port shuttle to prevent dust and debris from scattering on the ground. The worm gear structure has a self-locking function to prevent the cleaning brush 2 from rotating in the opposite direction due to external force, which would affect the cleaning effect.

[0045] The worm gearbox enables stable transmission of the drive motor 7 to the sweeping brush 2, and its self-locking characteristic enhances the anti-interference capability during operation, ensuring that the sweeping brush always operates within the set speed range. The dust collection bin 3 effectively collects the swept dust and debris, further preventing the spread of pollutants and improving the on-site working environment. The overall structure is compact and operates smoothly, improving the safety and cleanliness of the equipment, reducing the amount of manual cleaning work, and enhancing the automation and practicality of the system.
