[0002] A belt conveyor is a commonly used material conveying device that can convey a variety of solid materials, such as ores, grains, solid waste residues, etc. The belt conveyor has the advantages of high conveying efficiency, strong conveying capacity, stable operation, etc., but there are also disadvantages, such as dust raising. If granular materials are transported, some finer materials will adhere to the surface of the belt and move with the belt. Due to the natural evaporation effect, the finer materials become dry. With the vibration during the operation of the belt, they continuously fall off from the surface of the belt, either scatter on the ground or float in the air, causing dust to fly, affecting the service life of instruments and meters in the workplace, endangering the physical health of workers, and there is a possibility of deflagration and explosion. Therefore, it is imperative to control the dust on the belt surface.

[0003] At present, the commonly adopted treatment solution is to install a scraper cleaning mechanism, and its structure is a fixed type or a counterweight compensation mechanism. The disadvantage is that after the conveyor operates for a period of time, the head of the scraper becomes shorter due to wear, generating a gap between the scraper and the belt. The dust and mud adhered to the surface of the belt can pass through the gap, and the scraper fails to play a cleaning role. Summary of the Utility Model

[0004] The existing conveyor belt treatment solution is to install a scraper cleaning mechanism, and its structure is a fixed type or a counterweight compensation mechanism. The disadvantage is that after the conveyor operates for a period of time, the head of the scraper becomes shorter due to wear, generating a gap between the scraper and the belt. The dust and mud adhered to the surface of the belt can pass through the gap, resulting in the technical problem that the scraper fails to play a cleaning role. In view of the deficiencies of the prior art, the utility model provides a belt cleaning device for a belt conveyor.

[0011] Beneficial effects

[0012] The utility model provides a belt cleaning device for a belt conveyor, which solves the technical problem that the existing conveyor belt treatment scheme is to install a scraper cleaning mechanism, the structure of which is a fixed type or a counterweight compensation mechanism. The disadvantage is that after the conveyor operates for a period of time, the head of the scraper becomes short due to wear and a gap is generated between the scraper and the belt. The dust and mud adhered to the surface of the belt can pass through the gap, and the scraper fails to play a cleaning role. The utility model is installed below the return belt and near the head of the machine. The rotary brush is in contact with the conveyor belt. When the conveyor belt runs, the conveyor belt drives the rotary brush and the driving and discharging assembly to move. Since the double rotary brushes adopt a groove staggered form, in the process of the continuous rotation of the rotary brushes, all the materials and dust adhered to the working surface of the conveyor belt are scraped off and fall into the dust collection box. The dust collection box transports the materials to the designated sewage discharge tank through the driving and discharging assembly, reducing the labor intensity of the staff and preventing the overflow of materials and dust.

When the conveyor belt rotates, it can provide power for the driving and discharging assembly, so that the debris in the collection hopper 7 is transported to a designated sewage tank outside.

[0020] In this embodiment, it is further set that a plurality of grooves are formed on the rolling brush 6, and the grooves are staggered with the rolling brush 6;

[0021] When the rolling brushes 6 on the pair of first shafts 5 rotate simultaneously, they can alternately clean the working surface of the conveyor belt below.

[0022] In this embodiment, it is further set that the driving and discharging assembly includes an upper connecting frame 8, the upper connecting frame 8 is respectively fixedly installed on the side wall surfaces of a pair of the channel steels 2, a second shaft rod 9 is rotatably installed between the pair of channel steels 2, a roller 10 is fixedly installed on the second shaft rod 9, the roller 10 is in contact with the non-working surface of the conveyor belt, the roller 10 is located between the pair of channel steels 2, a first sprocket is fixedly installed on the second shaft rod 9 and between the channel steel 2 and the upper connecting frame 8, a discharge box 11 is fixedly installed on the lower wall surface of the collecting hopper 7, and the discharge box 11 communicates with the collecting hopper 7. One end of the discharge box 11 is provided with a discharge port, a screw rod 12 is rotatably installed in the discharge box 11, one end of the screw rod 12 penetrates through the discharge box 11 and is fixedly installed with a second sprocket, and a chain 13 is meshed and connected between the second sprocket and the first sprocket;

[0023] When the conveyor belt rotates, since the roller 10 is in contact with the non-working surface of the conveyor belt, the roller 10 is driven by a horizontal driving force under the action of friction, and then the roller 10 rotates under the action of the second shaft rod 9. The second shaft rod 9 drives the first sprocket to rotate. Since a chain 13 is connected between the first sprocket and the second sprocket, the second sprocket rotates, and the second sprocket drives the screw rod 12 to rotate. Since the screw rod 12 is provided with spiral blades, the materials in the discharge box 11 can be discharged from the discharge box 11 along the path of the spiral blades.

[0024] In this embodiment, it is further set that a support frame 14 is fixedly installed on the lower wall surface of the channel steel 2 and on one side of the upper connecting frame 8, a tensioning sprocket 15 is rotatably installed on the support frame 14, and the tensioning sprocket 15 is meshed with the chain 13;

[0030] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0031] Embodiment: As can be seen from the accompanying drawings of the specification, when the conveyor belt body 1 is working, its conveyor belt needs to be cleaned. When the conveyor belt rotates, since the rotary brush 6 contacts the working surface of the conveyor belt below, when the conveyor belt rotates, the rotary brush 6 can clean the working surface of the conveyor belt below (since the conveyor belt body 1 is used to convey coal mine materials, the speed of the conveyor belt during the operation of the conveyor belt body 1 is two meters per second. Therefore, the rotation direction of the rotary brush 6 is the same as the direction of the conveyor belt, providing a forward resistance to the conveyor belt, and then cleaning the conveyor belt). The cleaned debris falls into the collection hopper 7 for collection. When the conveyor belt rotates, since the roller 10 contacts the non-working surface of the conveyor belt, the roller 10 is driven by a horizontal driving force under the action of friction, and then the roller 10 rotates under the action of the second shaft rod 9. The second shaft rod 9 drives the first sprocket to rotate. Since a chain 13 is connected between the first sprocket and the second sprocket, the second sprocket rotates, and the second sprocket drives the screw rod 12 to rotate. Since the screw rod 12 is provided with screw blades, the materials in the discharge box 11 can be moved out of the discharge box 11 along the path of the screw blades, so that the debris in the collection hopper 7 is transported to a designated sewage trough outside.
