Description

Technical Field

[0001] This utility model relates to the field of mining cleaning equipment technology, and in particular to a self-driven roller brush coal sweeper for conveyor belts used in waste rock dumps. Background Technology

[0002] As the core equipment for continuous bulk material transportation, belt conveyors inevitably accumulate material on their belts after transporting materials. If not thoroughly cleaned, this adhered material will travel with the belt to the return section and spill along the way, causing a series of problems such as a deteriorated working environment, accelerated equipment wear, and increased running resistance. Therefore, a cleaner is usually installed at the head roller of the conveyor to scrape off the adhering material from the belt's working surface.

[0003] Currently, the most widely used head sweeper is the ordinary scraper sweeper. Its working principle is to use the scraper blade with a certain degree of elasticity and hardness, which is perpendicular or inclined to the belt surface with a certain preload, and scrapes off the adhering material through direct line contact or surface contact.

[0004] However, in steep uphill transport operations such as those involving waste rock dumping, anti-slip belts with raised patterns are commonly used to prevent material slippage and conveyor belt reverse movement. These raised patterns significantly increase friction with the material, ensuring reliable transport. However, when a flat scraper contacts the patterned belt, it can only reach the top of the raised pattern, failing to effectively reach the recessed grooves. This results in a large amount of fine material adhering to the grooves and raised sidewalls not being removed. This unremoved material continues to fall along the conveyor line due to the vibration of idlers and supports, forming a large accumulation below the conveyor. To maintain normal equipment operation, increased manual labor is required for cleaning along the line, significantly increasing labor and safety costs. Utility Model Content

[0005] Therefore, it is necessary to provide a self-driven roller brush type coal sweeper for conveyor belts used in waste rock dumps to address the above-mentioned technical problems. This sweeper can effectively remove the material adhering to the bottom of the belt, reduce the amount of sediment accumulation under the conveyor, and lower labor costs.

The roller brush is positioned below the conveyor belt and abuts against the conveyor belt. The shaft of the roller brush is perpendicular to the transmission direction of the conveyor belt, and the two ends of the roller brush shaft are rotatably connected to the first rotary connection assembly and the second rotary connection assembly, respectively. The driven sprocket is located at the end of the roller brush near the drive sprocket and is fixedly connected to the shaft of the roller brush; Both the drive sprocket and the driven sprocket mesh with the transmission chain. The drive sprocket is used to drive the driven sprocket to rotate through the transmission chain, thereby driving the roller brush to rotate and clean the conveyor belt.

[0014] It should be noted that in the description of this utility model, "upper," "lower," "top," "bottom," and orientation or positional relationship are based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] In one embodiment, such as Figure 1 As shown, the self-driven roller brush type coal sweeper for conveyor belts in waste rock dumps of this utility model includes: A drive sprocket 100 is fixedly mounted on one end of the lower idler roller 300 of the belt conveyor for waste rock disposal. The axis of the drive sprocket 100 coincides with the axis of the lower idler roller 300.

[0016] Drive chain. In this embodiment, the drive chain is a single-row chain.

[0017] The roller brush 200 assembly is fixedly connected to the frame 400 of the waste rock dump belt conveyor. The roller brush 200 assembly is provided with a roller brush 200, a first rotating connection assembly, a second rotating connection assembly, and a driven sprocket 600.

[0018] Specifically, the roller brush 200 is installed under the conveyor belt 500 at a distance of about 15 meters from the head of the conveyor belt. The roller brush 200 is a nylon roller brush, which includes the roller brush 200 shaft and nylon bristles distributed on the shaft. It can clean the conveyor belt 500 and clean the entire lower surface of the belt during the cleaning process.

[0019] The first and second rotary connecting assemblies are respectively disposed on both sides of the conveyor belt 500 and are both fixedly connected to the frame 400 of the waste rock dump belt conveyor. The roller brush 200 is disposed below the conveyor belt 500 and abuts against the conveyor belt 500. The shaft of the roller brush 200 is perpendicular to the transmission direction of the conveyor belt 500, and the two ends of the shaft of the roller brush 200 are rotatably connected to the first and second rotary connecting assemblies respectively.

[0020] Driven sprocket 600 is located at the end of roller brush 200 near drive sprocket 100 and is fixedly connected to the shaft of roller brush 200. Both drive sprocket 100 and driven sprocket 600 are engaged with the transmission chain. Drive sprocket 100 is used to drive driven sprocket 600 to rotate via the transmission chain, thereby driving roller brush 200 to rotate and clean conveyor belt 500.

[0021] In this embodiment, when the waste rock removal belt conveyor is started, the conveyor belt 500 drives the lower belt idler roller 300 to rotate, the lower belt idler roller 300 drives the drive sprocket 100 to rotate, and the drive gear drives the driven sprocket 600 to rotate through the transmission chain. The driven sprocket 600 drives the roller brush 200 to rotate. During the rotation, the roller brush 200 can clean the entire lower surface of the conveyor belt 500, whether it is the top of the convex surface of the pattern or the recessed groove area. It can effectively remove the material adhering to the lower surface of the conveyor belt 500, greatly reduce the accumulation of waste rock under the belt conveyor, and save labor costs.

[0022] In one embodiment, the first rotating connection assembly is provided with a first connecting frame 210, a first bearing seat 220 and a first bearing, and the second rotating connection assembly is provided with a second connecting frame 230, a second bearing seat and a second bearing; The first bearing and the second bearing are respectively sleeved on both ends of the shaft of the roller brush 200.

The first connecting frame 210 and the second connecting frame 230 are both fixedly connected to the frame 400 of the waste rock dump belt conveyor.

[0023] The two ends of the shaft of the roller brush 200 are rolled together by the first bearing and the second bearing, which has high rolling efficiency.

[0024] In one embodiment, the diameter ratio of the drive sprocket 100 to the driven sprocket 600 is 1:1 to 6. For example, the drive sprocket has an outer diameter of 202 mm and a mounting hole of 130 mm; the driven sprocket has an outer diameter of 82 mm and a mounting hole of 38 mm. When the diameter of the drive sprocket 100 is larger than that of the driven sprocket 600, the rotational speed of the driven sprocket 600 can be increased, enhancing the cleaning effect of the roller brush 200.

[0025] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
