Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically to a cleaning device for the return trip of a mining belt conveyor. Background Technology

[0002] A belt conveyor is short for a belt conveyor. There are fixed and mobile types. It has a simple structure and high efficiency. It is a continuous conveying machine that uses a flexible conveyor belt as the material carrying and traction component. An endless conveyor belt wraps around a drive drum and a redirecting drum. The upper and lower branches between the two drums are supported by several idlers. The material is placed on the upper branch, and the conveyor belt and the material are dragged by the friction between the drive drum and the belt. However, when the return belt cleaning device used for mine conveyor belts is cleaning, the waste material cleaned will fall under the return belt and accumulate at the bottom of the mine conveyor belt. The accumulated flammable materials such as coal powder and sulfur powder may spontaneously combust due to oxidation and heating or external ignition sources after a long period of accumulation, causing a fire. At the same time, after a long period of accumulation, it will bury the low equipment foundation and idler roller support, affecting the normal operation of the equipment. Therefore, a return belt cleaning device for mine conveyor belts is proposed. Utility Model Content

The driven component includes an installation port opened on the surface of the waste conveying shell 1, a bearing seat 7 fixedly connected to the surface of the waste conveying shell 1, a rotating shaft 6 fixedly connected to the inner ring of the bearing seat 7, and two sprockets 8 fixedly connected to the outer surface of the rotating shaft 6. The output end of the reducer 4 is connected to one end of the shaft 6, and the chain 9 is mounted on the surface of the sprocket 8.

[0018] Specifically, the reducer 4 is fixed to the outer surface of the waste conveying shell 1 by bolts. The output shaft of the motor 5 is connected to the input shaft of the reducer 4. The output shaft of the reducer 4 is connected to one end of the rotating shaft 6 through a coupling. The rotating shaft 6 is supported by two bearing seats 7, and two sprockets 8 are fixed on the rotating shaft 6. The power of the motor 5 is adjusted and increased by the reducer 4, which drives the rotating shaft 6 and the sprockets 8 to rotate synchronously.

[0019] Furthermore, the waste collection component includes a waste collection shell 2, a guide plate 26 fixedly connected to the inner wall of the waste collection shell 2, and a discharge port 27 opened on the outer surface of the waste collection shell 2.

[0020] Specifically, the waste collection shell 2 is located below one end of the waste conveying shell 1, and an inclined guide plate 26 is welded inside it to guide the collected waste to slide towards the discharge port 27. The discharge port 27 can be connected to a cloth bag or a transport device to realize centralized processing of waste.

[0021] Furthermore, the adjusting component includes a mounting bracket 13 fixedly connected to the inner wall of the hopper 12, a plurality of threaded grooves formed on one side of the mounting bracket 13, an adjusting bracket 14 provided on the surface of the mounting bracket 13, an adjusting hole 15 formed on the surface of the adjusting bracket 14, and an adjusting bolt 16 threadedly connected to the inner wall of the threaded groove.

[0022] Specifically, the mounting frame 13 is welded to the inner wall of the hopper 12, and its surface is machined with multiple threaded grooves. The adjusting frame 14 is fixed to the mounting frame 13 by adjusting bolts 16. The adjusting bolts 16 pass through the adjusting holes 15 on the adjusting frame 14 and are screwed into the threaded grooves of the mounting frame 13. Loosening the adjusting bolts 16 can move the position of the adjusting frame 14 relative to the mounting frame 13. After adjustment, tightening the bolts can fix it, thereby changing the overall installation position of the scraping component.

[0023] Furthermore, the scraping component includes a lifting housing 19, a slider 20 slidably connected to the inner wall of the lifting housing 19, a connecting piece 21 fixedly connected to one end of the slider 20, a snap-fit ​​seat 22 fixedly connected to the surface of the connecting piece 21, a scraper 23 fixedly connected to the inner wall of the snap-fit ​​seat 22 and a plurality of springs 25 fixedly connected to one side of the connecting piece 21, a baffle 24 fixedly connected to the surface of the scraper 23, a sliding groove is provided on the inner wall of the lifting housing 19, a sliding block is slidably connected to the inner wall of the sliding groove, and one side of the sliding block is connected to the slider 20; The snap-fit ​​base 22 has multiple connection holes on one side and multiple threaded openings on the inner wall of the snap-fit ​​base 22. The inner wall of the threaded openings is threaded with connecting bolts, and the surface of the scraper 23 has multiple reserved holes for mating connecting bolts.

[0024] Specifically, the lifting housing 19 is fixed on the adjusting frame 14. The slider 20 can slide up and down by engaging with the sliding groove on the inner wall of the lifting housing 19 through the sliding block on it. The connecting piece 21 is fixed at the lower end of the slider 20. The upper end of the spring 25 presses against the top of the inside of the lifting housing 19, and the lower end acts on the connecting piece 21 to provide downward elastic pressure for the entire scraping component. The scraper 23 is fastened to the clamping seat 22 by inserting it into the clamping seat 22 and by using a connecting bolt to pass through the connecting hole of the clamping seat 22 and the reserved hole of the scraper 23 and screwing it into the threaded opening. The baffle 24 is welded to the scraper 23 to prevent material splashing. This design allows the scraper 23 to adapt to the undulations of the belt surface and is easy to replace after wear.

[0025] Furthermore, a support frame 17 is fixedly connected to the bottom of the waste conveying shell 1. A reinforcing plate 18 is provided on the outer surface of the support frame 17. Multiple reinforcing frames 11 are provided on the inner wall of the waste conveying shell 1. The reinforcing frames 11 are threadedly connected to the waste conveying shell 1 by bolts.

[0026] Specifically, the support frame 17 is welded to the bottom of the waste conveying shell 1 and serves as the main load-bearing structure. The reinforcing plate 18 is welded to the side of the support frame 17 to increase the overall rigidity. Multiple reinforcing frames 11 are bolted to the inner wall of the waste conveying shell 1 to prevent the shell from deforming due to the tension of the chain 9 and the impact of the material.

[0027] The workflow of this application: When the motor 5 is started, the output power of the motor 5 is adjusted and the torque is increased by the reducer 4. The output shaft of the reducer 4 drives the rotating shaft 6 to rotate. The two sprockets 8 fixed on the rotating shaft 6 rotate synchronously. The sprockets 8 drive the two chains 9 surrounding the inside of the waste conveying shell 1 to start circulating. The multiple scrapers 10 fixed on the chains 9 move accordingly to form a continuous scraping conveying surface. The residual material (such as coal powder and mineral powder) carried on the lower surface of the return belt of the conveyor belt runs to the top of the hopper 12. Multiple sets of scraping components installed on the hopper 12 start to work. Under the continuous elastic pressure applied by the spring 25, the scraper 23 is tightly attached to the surface of the belt. The scraper 23 scrapes off most of the material attached to the belt. The scraped material falls directly into the hopper 12 below. The baffle 24 effectively prevents the material from splashing during the scraping process. The scraper 23 can adapt to the slight undulation of the belt through the cooperation of the slider 20 and the sliding groove, ensuring a stable scraping effect. The waste material falling into the hopper 12 is guided by the conical structure of the hopper 12 and falls into the waste material conveying shell 1 directly below it. At this time, the continuously running scraper 10 passes under the discharge port of the hopper 12, scrapes up the waste material that has gathered there, and conveys it to one end along the bottom of the waste material conveying shell 1. The reinforcing frame 11 ensures that the waste material conveying shell 1 maintains its shape stability under the tension of the chain 9 and the load of the material. The waste material conveyed to the end of the waste conveying shell 1 by the scraper 10 falls into the lowest waste collection shell 2 under the action of gravity. The waste material falls on the guide plate 26 inside the waste collection shell 2 and slides along the inclined surface of the guide plate 26 to the discharge port 27. The waste material is finally discharged through the discharge port 27 and can be connected to a transport vehicle or a centralized processing system to complete the automatic collection of waste. In addition, scraper position adjustment: when it is necessary to adjust the contact position or angle between the scraper 23 and the belt, the adjusting bolt 16 can be loosened, the position of the adjusting bracket 14 on the mounting bracket 13 can be moved, and the bolt can be tightened after the adjustment is completed to achieve the overall positioning of the scraper component. Scraper 23 replacement: when the scraper 23 is worn, simply unscrew the connecting bolt to remove the old scraper 23 from the snap-fit ​​seat 22 and replace it with a new scraper 23. Maintenance is simple and quick. In summary, this device achieves fully automated processing of the return material of the belt conveyor through the combination of "fine scraping by elastic scraper 23" and "continuous conveying by chain 9 and scraper 10". Its elastic clamping and adjustable design can effectively adapt to the working conditions of the belt, ensuring thorough cleaning while protecting the belt from damage, and greatly improving cleaning efficiency.
