Description

Technical Field

[0001] This utility model relates to the field of coal mining equipment technology, and in particular to a coal cleaning device for a scraper conveyor. Background Technology

[0002] Scraper conveyors are common continuous conveying equipment, mainly used for transporting bulk materials or small items over a certain distance. They consist of a series of scrapers connected by chains or sprockets, running on fixed guide rails to move materials from one point to another. Due to their simple structure, high reliability, and ease of maintenance, scraper conveyors are widely used in industries such as mining, metallurgy, chemicals, grain processing, and coal mining.

[0003] Existing scraper conveyors do indeed face the problem of material residue on the scrapers during operation, especially when handling easily adhering materials such as coal, which can easily result in loose coal adhering to the machine. This problem not only reduces the efficiency of the equipment but also increases additional cleaning costs and time. Currently, the common solution usually relies on manual cleaning, but due to limited operating space, workers often have to work in confined environments that may contain dust and other harmful substances. This is not only inefficient but also poses a potential threat to the health and safety of workers.

[0004] To improve this situation, automated or semi-automated cleaning systems can be considered to replace manual operation. Therefore, there is an urgent need to design a scraper conveyor coal cleaning device that can improve cleaning efficiency, reduce downtime, and reduce the risks associated with manual cleaning, thereby providing a safer working environment for operators. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a scraper conveyor coal cleaning device, which can improve cleaning efficiency, reduce downtime, and reduce the risks associated with manual cleaning.

[0006] The technical solution of this utility model is: a scraper conveyor coal cleaning device, including a mounting frame, a frame body, a guide plate, cleaning rollers, a second pulley set, and a transmission assembly. A frame body with an inclined bottom is set on the mounting frame. The frame body is located below the conveying section of the scraper conveyor. A guide plate is rotatably set on one side of the bottom of the frame body, so that the guide plate is inclined to facilitate the transportation of coal. The end of the guide plate faces the discharge port of the scraper conveyor. Two cleaning rollers that are in contact with the conveying section of the scraper conveyor are rotatably set between the inner sides of the frame body to scrape off the attached floating coal. The ends of the two cleaning rollers are connected by the second pulley set. A transmission assembly is also set on the frame body, which can drive the cleaning rollers to rotate automatically.

[0007] Furthermore, it also includes tension springs, with tension springs installed between the two sides of the frame and the guide plate, allowing the guide plate to vibrate during operation.

[0008] Furthermore, the transmission assembly includes a motor, a crushing roller, and a first pulley set. The motor is installed on the side of the frame facing the feed port of the scraper conveyor. The output shaft of the motor is connected to the crushing roller for crushing coal. The other end of the crushing roller is provided with a first pulley set between it and the adjacent cleaning roller.

[0009] Furthermore, it also includes an air storage frame and nozzles. An air storage frame is set between the two sides of the mounting frame, located on the front side of the frame. Multiple nozzles are connected to the top of the air storage frame, and all nozzles pass through the frame and face the scraper conveyor.

[0010] Furthermore, the nozzle's orifice is bent upwards to fit the position of the scraper conveyor.

[0011] Furthermore, the cleaning roller is made of steel.

[0012] Beneficial effects: This invention uses a motor to drive the rotation of the cleaning roller and the crushing roller. The cleaning roller is mainly responsible for removing loose coal and larger coal particles attached to the surface of the conveyor, while the crushing roller is specifically used to crush larger coal particles into smaller ones. In this way, not only can the coal particles stuck on the scraper conveyor be processed automatically, but the entire cleaning process can also be made more systematic and streamlined. The application of this technology not only greatly improves the efficiency and reliability of coal mine transportation, but also eliminates the safety hazards that may be caused by manual cleaning, thus providing a safer working environment and a more efficient cleaning method for coal mine production.

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Example: A coal cleaning device for a scraper conveyor, such as Figures 1-5 As shown, the device includes a mounting frame 1, a frame 2, a guide plate 3, a cleaning roller 8, a second pulley set 9, and a transmission assembly. The mounting frame 1 is a hollow rectangular frame, serving as the mounting carrier for all components of the device. A frame 2 with a sloping bottom is positioned between the two sides of the mounting frame 1. The frame 2 is located below the conveying section of the scraper conveyor. A guide plate 3 is rotatably mounted on one side of the bottom of the frame 2, making the guide plate 3 inclined. This allows the movement of coal to be accelerated by the inclined surface, making the overall operation more efficient and faster, thus improving the overall working efficiency of the device. Furthermore, the end of the guide plate 3 faces the discharge port of the scraper conveyor to ensure more concentrated coal collection, providing convenience for subsequent operations and reducing the workload of personnel. Two cleaning rollers 8 are rotatably mounted on the left and right sides of the frame 2, which are in contact with the conveying section of the scraper conveyor. The cleaning rollers 8 are made of steel, which can ensure sufficient strength and durability to scrape off the attached loose coal and the coal material attached to the scraper conveyor, so that the cleaning can be more thorough and efficient. The ends of the two cleaning rollers 8 are connected by a second pulley group 9. A transmission component is also provided on the frame 2, which can drive the cleaning rollers 8 to rotate automatically, thereby realizing the automated operation of the device. Compared with traditional manual handling, this is easier and simpler, which can greatly reduce the workload of personnel, provide convenience for cleaning work, and greatly reduce safety risks.

[0021] like Figure 2 As shown, it also includes a tension spring 4. Tension springs 4 are provided between the two sides of the frame 2 and the guide plate 3, so that the guide plate 3 can shake and accelerate the sliding coal, and help the coal slide down better, so as to improve the working efficiency.

[0022] like Figure 3 and Figure 4As shown, the transmission assembly includes a motor 5, a crushing roller 6, and a first pulley set 7. The motor 5 is installed on the side of the frame 2 facing the feed port of the scraper conveyor. The output shaft of the motor 5 is connected to the crushing roller 6 for crushing coal. The other end of the crushing roller 6 is provided with the first pulley set 7 between it and the adjacent cleaning roller 8, which can crush larger coal materials for subsequent cleaning and collection operations.

[0023] like Figure 1 and Figure 5 As shown, it also includes an air storage frame 10 and nozzles 11. An air storage frame 10 is set between the left and right sides of the mounting frame 1, located on the front side of the frame 2. Four nozzles 11 are connected to the top of the air storage frame 10. The nozzles 11 are bent upwards to fit the position of the scraper conveyor. All nozzles 11 pass through the frame 2 and face the scraper conveyor. The strong airflow can blow away the stubborn coal on the scraper conveyor, making the cleaning process more effective and complete.

[0024] When it is necessary to clean the floating coal and stagnant coal on the scraper conveyor, the device is installed at the discharge port of the scraper conveyor via the mounting frame 1, so that the cleaning roller 8 in the device can be placed below the conveying section to clean the stagnant coal at the rear. Then, the motor 5 is started, and the motor 5 drives the crushing roller 6 to rotate. As the crushing roller 6 rotates, it drives the first pulley group 7 to rotate, which in turn drives the connected cleaning roller 8 to rotate, which in turn drives the second pulley group 9 to rotate to drive the other cleaning roller 8. From then on, the two cleaning rollers 8 rotate automatically in sync with the operation and come into contact with the scraper conveyor above to scrape the coal. As the floating coal falls, the guide plate 3 is pressed down, causing the tension spring 4 to deform and reciprocate due to its elasticity. This creates a shaking discharge effect on the guide plate 3, while the coal accelerates its descent and enters the rotating crushing roller 6 for crushing, allowing it to be incorporated into the floating coal for subsequent collection and processing. An air pump can also be connected to the air storage frame 10 to introduce airflow into it, which is then sprayed out by the nozzle 11 to agitate the scraper conveyor and clean stubborn coal. This continuous operation enhances the effectiveness of the scraper conveyor and avoids the risks associated with manual cleaning.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
