Description

Technical Field

[0001] This invention relates to the field of conveyor belt cleaning, specifically a conveyor belt cleaning component for a mining belt conveyor. Background Technology

[0002] Mining belt conveyors are indispensable material conveying equipment in mining production. As the core component for material carrying and transmission, the conveyor belt is constantly exposed to complex environments such as dust, coal slime, and ore fragments, making its surface highly susceptible to the accumulation of various contaminants. If these contaminants are not removed promptly and thoroughly, they will not only accelerate surface wear and shorten the conveyor belt's service life, but may also cause belt misalignment and slippage due to contaminant accumulation, affecting the normal operation of the conveyor and, in severe cases, even leading to equipment failure, threatening the continuity and safety of mining production.

[0003] Currently, existing conveyor belt cleaning devices for mining belt conveyors often suffer from complex structures and inconvenient operation. Most are fixed installations; while they allow adjustment of the conveyor belt's position by opening it, this fixed position prevents cleaning of other parts of the conveyor. Furthermore, the cleaning components of existing devices are mostly set at fixed angles, lacking the ability to be adjusted by swing, making it difficult to thoroughly clean dirt from the conveyor belt surface. This is especially problematic for stubborn deposits, resulting in poor cleaning effectiveness and residue buildup. Summary of the Invention

[0004] The purpose of this invention is to provide a conveyor belt cleaning component for a mining belt conveyor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A conveyor belt cleaning assembly for a mining belt conveyor includes a limiting groove fixed to the bottom of the conveyor body. Two limiting sliders are slidably connected inside the limiting groove. Each limiting slider is connected to a movable bracket. A connecting base plate is connected between the two movable brackets. A cleaning mechanism is provided in the middle of the connecting base plate. The cleaning mechanism includes a first electric telescopic rod fixed above the connecting base plate. A swing plate is rotatably connected to the bottom of the first electric telescopic rod. Cleaning wheels that are in a rotating state are provided below both ends of the swing plate. During the swinging process of the swing plate, the cleaning wheels clean the conveyor belt of the conveyor.

[0006] As a further aspect of the present invention: the movable support includes a first support fixedly connected to the limiting slider and a sleeve slidably connected to the first support, a second electric telescopic rod fixedly connected to the first support, the top of the second electric telescopic rod being fixedly connected to the sleeve, and the sleeve having a square cross-section.

[0009] As a further aspect of the present invention: the connecting base plate is also provided with a power unit for driving the swing plate to swing, and during the swing of the power unit, the cleaning wheel deviates from the center position of the conveyor belt by an equal distance.

[0010] As a further embodiment of the present invention: the power unit includes a second motor, a rotating disk is fixedly connected to the output shaft of the second motor, a drive rod is fixedly connected to the side of the rotating disk away from the second motor, the drive rod is located at an eccentric position of the rotating disk, a transmission rod is rotatably connected to the outer side of the first electric telescopic rod, a transmission groove is opened in the middle of the transmission rod, the drive rod is slidably connected to the transmission groove, a driven rod is connected to the end of the transmission rod, the driven rod is fixedly connected to the swing plate, and the swing plate swings when the driven rod rotates around the first electric telescopic rod.

[0011] As a further embodiment of the present invention: an arc-shaped groove is provided on the connecting substrate, and the driven rod passes through the arc-shaped groove and slides in cooperation with the arc-shaped groove.

[0012] As a further embodiment of the present invention: the two cleaning wheels are respectively located on the outside of the two movable supports, and when the movable supports abut against the conveyor support legs, the cleaning wheels are flush with the end of the conveyor belt of the conveyor.

[0013] As a further embodiment of the present invention: the conveyor body includes support legs and a conveyor belt disposed on the top of the support legs, the conveyor belt being driven by a power mechanism.

[0014] Compared with existing technologies, the advantages of this invention are: The invention has a simple structure and is easy to use. The slider design allows the device to slide left and right. During sliding, the extension and retraction of the electric telescopic rod adjusts the specific cleaning position of the cleaning wheels.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] As a core piece of equipment for material transport in mining production, the cleanliness of the conveyor belt directly affects conveying efficiency, equipment lifespan, and production safety. If material remains on the conveyor belt surface, it can not only lead to material loss but also cause malfunctions such as belt misalignment and slippage, and in severe cases, even disrupt the normal operation of the entire mining production process. Therefore, this article introduces a well-structured and highly effective conveyor belt cleaning component for mining belt conveyors. This component enables comprehensive and efficient cleaning of the conveyor belt and is suitable for the complex working environment of mines. The following section will detail its overall structure, the specific components, and its working principle.

[0026] Please refer to the attached diagram. This conveyor belt cleaning assembly is installed above the conveyor body to achieve precise cleaning of the bottom of the conveyor belt. Its core structure revolves around three main modules: a limiting sliding mechanism, a support connecting mechanism, and a cleaning execution mechanism. These modules work together to ensure the stability and reliability of the cleaning operation. The conveyor body, serving as the foundation for the entire cleaning assembly, mainly consists of support legs and a conveyor belt mounted on top of the support legs. The conveyor belt is driven by a matching power mechanism to continuously transport materials, while the cleaning assembly specifically removes any residual materials adhering to the conveyor belt during operation.

[0027] A limiting chute 1 is fixedly connected to the bottom of the conveyor body. This limiting chute 1 adopts a trough-shaped structure, and its length is adapted to the width of the conveyor belt. This provides stable guidance for the sliding of subsequent components, preventing incomplete cleaning due to component misalignment during the cleaning process. Inside the limiting chute 1, two limiting sliders 2 are slidably connected. The dimensions of the limiting sliders 2 match the cavity of the limiting chute 1, ensuring that the sliders can slide smoothly along the chute without jamming or misalignment.

[0028] To support and adjust the position of the cleaning mechanism 5, each limiting slider 2 is fixedly connected to a movable bracket 3. The two movable brackets 3 are symmetrically distributed. Their main function is to support the connecting base plate 4 and the cleaning mechanism 5, and to drive the entire cleaning mechanism 5 to slide along the limiting slide groove 1, thereby adapting to the cleaning needs of conveyor belts of different widths, or to carry out targeted cleaning of different areas of the conveyor belt. It is worth noting that the two movable brackets 3 are fixedly connected by the connecting base plate 4. The connecting base plate 4 serves as the mounting carrier of the cleaning mechanism 5, and its structural stability directly affects the cleaning effect. Therefore, the connecting base plate 4 is made of high-strength steel plate to ensure that it can withstand the weight of the cleaning mechanism 5 and the impact force during the cleaning process.

[0029] The movement of the limiting slider 2 is preferably achieved by setting a corresponding electric mechanism. It can be directly connected to the telescopic end of the electric telescopic rod to achieve movement, or it can be driven by a motor. The ability of the roller screw to convert rotational motion into linear motion is used to achieve the movement of the limiting slider 2, thereby realizing the movement of the cleaning position.

[0030] To further improve the connection stability between the connecting base plate 4 and the movable bracket 3, channel steel 12 is fixedly connected to both ends of the connecting base plate 4. The channel steel 12 is fixedly connected to the movable bracket 3 by bolts. The structural strength of the channel steel 12 effectively disperses the pressure on the connecting base plate 4, avoiding problems such as loosening and deformation after long-term use. At the same time, the groove structure of the channel steel 12 can also play a certain protective role for the connection part, preventing dust and debris in mining operations from entering the connection gap and affecting the reliability of the connection.

[0031] The movable support 3, serving as a support and adjustment component, directly determines the height adjustment capability of the cleaning mechanism 5 through its structural design. Specifically, the movable support 3 includes a first support 9 fixedly connected to the limiting slider 2 and a sleeve 10 slidably connected to the first support 9. The sleeve 10 has a square cross-section; a square structure provides better torsional resistance than a circular structure, effectively preventing rotation during sliding and ensuring precise height adjustment. To achieve height adjustment of the movable support 3, a second electric telescopic rod 11 is fixedly connected to the first support 9. The top of the second electric telescopic rod 11 is fixedly connected to the sleeve 10. The telescopic movement of the second electric telescopic rod 11 causes the sleeve 10 to slide up and down along the first support 9, thereby adjusting the height of the connecting base plate 4 and the cleaning mechanism 5. This ensures that the cleaning wheel 8 can closely contact the conveyor belt surface, guaranteeing a cleaning effect. The second electric telescopic rod 11 is mainly used to adjust the overall height of the cleaning mechanism 5, initially adjusting it to the required cleaning height; its telescopic accuracy is relatively low.

[0032] The cleaning mechanism 5 is the core actuator of the entire assembly. Installed in the middle of the connecting base plate 4, it is primarily used for cleaning the conveyor belt. The structural design of the cleaning mechanism 5 balances comprehensive cleaning with flexibility. Specifically, it includes a first electric telescopic rod 6 fixed above the connecting base plate 4. A swing plate 7 is rotatably connected to the bottom of the first electric telescopic rod 6. The swing plate 7 can swing around the bottom of the first electric telescopic rod 6, thereby driving the cleaning components at both ends to clean different positions of the conveyor belt, avoiding cleaning dead zones. The extension and retraction adjustment of the first electric telescopic rod 6 allows for fine-tuning of the cleaning force, and its extension and retraction accuracy is high.

[0033] Below both ends of the swing plate 7, there are rotating cleaning wheels 8. The cleaning wheels 8 are components that directly contact the conveyor belt and perform cleaning. Their bottoms are integrated cleaning brushes that effectively remove residual materials from the conveyor belt surface while preventing wear and tear, thus extending the conveyor belt's service life. To enable the rotation of the cleaning wheels 8, the cleaning mechanism 5 also includes cleaning shafts 13 rotatably connected to both ends of the swing plate 7. The bottoms of both cleaning shafts 13 are fixedly connected to the cleaning wheels 8. The rotation of the cleaning shafts 13 drives the cleaning wheels 8 to rotate synchronously, thereby enhancing the cleaning effect and improving cleaning efficiency.

[0034] To ensure the synchronous rotation of the two cleaning wheels 8, pulleys 14 are fixedly connected to the outer side of the middle of the cleaning shaft 13. A transmission belt 15 is sleeved between the two pulleys 14. Through the transmission action of the transmission belt 15, the two cleaning shafts 13 can rotate synchronously, thereby driving the two cleaning wheels 8 to rotate at the same speed, avoiding uneven cleaning effect due to inconsistent speeds. At the same time, one of the cleaning shafts 13 is connected to the output shaft of the first motor 16. The first motor 16 serves as the power source for the rotation of the cleaning wheel 8. By driving the cleaning shaft 13 to rotate, it drives the entire cleaning wheel assembly to operate, providing power support for the cleaning operation.

[0035] To enable the oscillating plate 7 to oscillate and allow the cleaning wheels 8 to thoroughly clean the conveyor belt, a power unit 17 is also installed on the connecting base plate 4 to drive the oscillating plate 7. The power unit 17 is designed so that during the oscillation of the oscillating plate 7, the distances of the two cleaning wheels 8 from the center of the conveyor belt remain equal. This design ensures that the cleaning wheels 8 apply consistent cleaning force to both sides of the conveyor belt, preventing one side from being thoroughly cleaned while the other is not, thus further improving the uniformity of cleaning. The single-oscillating cleaning mechanism 5 not only cleans the surface of the conveyor belt but also simultaneously cleans the upper surface of the belt conveyor during the oscillation process, preventing the equipment from having only a clean conveyor belt surface while other areas have significant dust and dirt.

[0036] The specific structure of the power unit 17 includes a second motor 18 fixedly mounted on the connecting base plate 4. The second motor 18 serves as the oscillating power source, and a rotating disk 19 is fixedly connected to its output shaft. A drive rod 20 is fixedly connected to the side of the rotating disk 19 away from the second motor 18, and the drive rod 20 is located at an eccentric position on the rotating disk 19. This design allows the drive rod 20 to perform circular motion when the rotating disk 19 rotates. Simultaneously, a transmission rod 21 is rotatably connected to the outside of the first electric telescopic rod 6. A transmission groove 22 is formed in the middle of the transmission rod 21, and the drive rod 20 is slidably connected to the transmission groove 22. When the drive rod 20 performs circular motion, it drives the transmission rod 21 to rotate around the first electric telescopic rod 6 through the transmission groove 22. A limit plate is fixedly connected to the end of the drive rod 20, thereby limiting the height position of the transmission rod 21 and ensuring that the relative position of the transmission rod 21 and the drive rod 20 remains unchanged. During the extension and retraction of the first electric telescopic rod 6, the transmission rod 21 slides in engagement with the extension end of the first electric telescopic rod 6.

[0037] To transmit the rotation of the transmission rod 21 to the swing plate 7, a driven rod 23 is connected to the end of the transmission rod 21. The driven rod 23 is located in the transmission groove 22 and swings with the swing of the transmission rod 21. The driven rod 23 and the transmission groove 22 can be rotatably connected or other connection methods can be adopted to ensure that the driven rod 23 swings synchronously during the swing of the transmission rod 21. The driven rod 23 is fixedly connected to the swing plate 7. When the transmission rod 21 rotates around the first electric telescopic rod 6, it will drive the driven rod 23 to rotate synchronously, thereby driving the swing plate 7 to swing around the bottom of the first electric telescopic rod 6, realizing the swing cleaning of the cleaning wheel 8. To limit the rotation trajectory of the driven rod 23 and ensure the stability of the swing, an arc-shaped groove 24 is provided on the connecting base plate 4. The driven rod 23 passes through the arc-shaped groove 24 and slides in fit with the arc-shaped groove 24. The curvature of the arc-shaped groove 24 is adapted to the rotation trajectory of the driven rod 23, which can effectively prevent the driven rod 23 from deviating during the rotation and ensure the swing accuracy of the swing plate 7.

[0038] In addition, to further optimize the cleaning effect, the two cleaning wheels 8 are located on the outside of the two movable supports 3 respectively. When the movable supports 3 abut against the conveyor support legs, the cleaning wheels 8 are flush with the end of the conveyor belt. This position design can ensure that the cleaning wheels 8 can cover the entire width of the conveyor belt, avoiding dead corners that cannot be cleaned at the end of the conveyor belt. At the same time, it can also prevent the cleaning wheels 8 from exceeding the range of the conveyor belt, causing unnecessary wear and energy waste.

[0039] In summary, the conveyor belt cleaning component of this mining belt conveyor achieves comprehensive and efficient cleaning of the conveyor belt through the coordinated operation of the limiting sliding mechanism, the supporting connecting mechanism, and the cleaning execution mechanism. Its sliding and height adjustment of the movable support 3 allows it to adapt to conveyor belts of different widths and heights; the power unit 17 drives the swing plate 7 to swing, causing the cleaning wheel 8 to achieve all-around cleaning and avoid cleaning dead spots; and the synchronous transmission structure ensures that the cleaning wheel 8 rotates at a consistent speed, improving cleaning uniformity. This component has a reasonable structure, is easy to operate, and provides excellent cleaning results, effectively solving the problem of cleaning conveyor belts in mining belt conveyors, extending equipment service life, and ensuring the continuous and stable operation of mining production.
