Description

Technical Field

[0001] This utility model relates to the field of belt conveyor cleaning technology, specifically an automatic cleaning device for belt conveyors. Background Technology

[0002] Belt conveyors are important transportation equipment for conveying bulk solid materials. When conveying various bulk materials, belt conveyors require one or more cleaning devices to continuously clean the residual material on the belt surface during operation in order to reduce material loss and ensure normal belt operation.

[0003] Existing belt sweepers generally suffer from the following problems:

[0004] (1) Incomplete cleaning: Single-stage scrapers are unable to remove highly adhesive materials, and residual materials cause secondary pollution and cause the conveyor belt to run off-track;

[0005] (2) High maintenance costs: Traditional scrapers need to be replaced as a whole after they wear out, which is costly, time-consuming to disassemble and assemble, and affects the continuity of production;

[0006] (3) Poor adaptability: The fixed-angle scraper cannot adapt to the uneven surface of the belt or the running condition, resulting in local missed cleaning or excessive wear;

[0007] (4) Cannot recycle materials independently: Spilled materials need to be cleaned up and recycled manually, resulting in a waste of manpower. Utility Model Content

[0008] To address the problem of incomplete belt cleaning during belt conveyor operation, resulting in secondary pollution from spilled residual materials and the need for manual cleaning and recycling, this utility model provides an automatic belt conveyor cleaning device.

[0009] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0010] An automatic cleaning device for a belt conveyor includes a belt conveyor body. Support plates are installed on both sides of the bottom surface of the belt conveyor body. A recycling conveyor is connected to the bottom end of the support plates. A plurality of adjustable spring tensioners are provided on the top side of the recycling conveyor. Clamping plates are provided on the top surface of the plurality of adjustable spring tensioners. A first cleaner and a pair of second cleaners are respectively provided between every two clamping plates. One side of the first cleaner is attached to the side of the belt conveyor body, and the top surface of the pair of second cleaners is attached to the bottom surface of the belt conveyor body.

[0011] Furthermore, the adjustable spring tensioner includes a screw and a connecting block. The screw is fixedly connected to the top side of the recycling conveyor. A rotating cylinder is threadedly connected to the outer wall of the screw. The connecting block is installed on the outer wall of the clamping plate. A hole is opened on one side of the connecting block and inserted into the top of the screw. A spring is sleeved on the outer wall of the screw. The spring is located between the rotating cylinder and the connecting block.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by rotating the rotating drum, its position on the screw can be changed, thereby adjusting the degree of spring compression and achieving flexible adjustment of the clamp height and pressure. The presence of the spring provides a continuous and stable tension, ensuring that the clamp always firmly fixes the first and second sweepers.

[0013] Furthermore, the clamping plate includes a plate, and a slot is provided on one side of the plate.

[0014] The advantages of adopting the above-mentioned further solution are that it facilitates the quick snapping and fixing of the first and second sweepers, the installation process is simple and convenient, and the slot design can effectively prevent the sweepers from shifting during operation, ensuring that the sweepers accurately clean the belt conveyor.

[0015] Furthermore, the first cleaner includes a first scraper, the top surface of which is configured as a single-sided scraping opening.

[0016] The beneficial effects of adopting the above-mentioned further solution are that it can accurately scrape the sides of the belt conveyor body, efficiently scrape off the material on the upper edge of the belt, and the single-sided scraping design can reduce damage to the belt edge, extend the belt service life, and at the same time ensure the cleaning effect and prevent material from spilling from the belt edge.

[0017] Furthermore, the second cleaner includes a second scraper, the top surface of which is configured as a double-sided scraping edge.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it can clean both sides of the bottom surface of the belt conveyor body at the same time. Compared with single-sided scraping, it can more thoroughly remove the material adhering to the bottom surface of the belt, improve cleaning efficiency, ensure the cleanliness of the bottom surface of the belt, and avoid material residue affecting the operation of the belt.

[0019] Furthermore, both the first and second scrapers are made of polyurethane.

[0020] The advantages of adopting the above-mentioned further solution are that polyurethane material has good wear resistance, which can maintain the shape and scraping performance of the scraper during long-term cleaning work, reducing the frequency of replacement. At the same time, polyurethane material is relatively soft, causing less damage to the belt of the belt conveyor during the cleaning process.

[0021] Furthermore, an interlocking assembly is provided between the belt conveyor body and the recycling conveyor. The interlocking assembly includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The movable end of the belt conveyor body is driven to connect the first synchronous pulley, and the movable end of the recycling conveyor is driven to connect the second synchronous pulley. The outer walls of the first and second synchronous pulleys are fitted with synchronous belts and are connected by synchronous belt drive.

[0022] The beneficial effect of adopting the above-mentioned further solution is that by connecting the belt conveyor body with the recycling conveyor, the two can operate synchronously. This allows the recycling conveyor to promptly collect the swept-down material, preventing material accumulation; simultaneously, synchronous operation allows for rational power distribution, preventing the recycling conveyor from idling, achieving energy savings, and improving the overall operating efficiency of the device.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This automatic belt conveyor cleaning device thoroughly cleans materials adhering to the conveyor belt by adding a material recovery device and a cleaner to the head section of the belt conveyor. It automatically recovers spilled materials, reduces labor costs and safety risks during coal dust cleaning, improves the cleaner design, and lowers maintenance and repair costs. Its design is simple, easy to maintain, stable, reliable, and highly adaptable. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] As an embodiment of this utility model, the adjustable spring tensioner 500 further includes a screw 5001 and a connecting block 5004. The screw 5001 is fixedly connected to the top side of the recycling conveyor 200. A rotating cylinder 5002 is threadedly connected to the outer wall of the screw 5001. The connecting block 5004 is installed on the outer wall of the clamping plate 600. A hole is opened on one side of the connecting block 5004 for insertion and connection with the top end of the screw 5001. A spring 5003 is sleeved on the outer wall of the screw 5001. The spring 5003 is located between the rotating cylinder 5002 and the connecting block 5004. By rotating the rotating cylinder 5002, its position on the screw 5001 can be changed, thereby adjusting the compression degree of the spring 5003 and realizing flexible adjustment of the height and pressure of the clamping plate 600. The presence of the spring 5003 can provide a continuous and stable tension force, ensuring that the clamping plate 600 always firmly fixes the first cleaner 700 and the second cleaner 800.

[0037] As an embodiment of this utility model, the clamping plate 600 further includes a plate 6001, and a slot 6002 is provided on one side of the plate 6001 to facilitate the quick insertion and fixing of the first cleaner 700 and the second cleaner 800.

[0038] As an embodiment of this utility model, the first cleaner 700 further includes a first scraper 7001. The top surface of the first scraper 7001 is configured as a single-sided scraping opening 7002, which can accurately scrape the side of the belt conveyor body 100, efficiently scrape off the material on the upper edge of the belt, and the single-sided scraping opening design can reduce damage to the belt edge, extend the belt service life, and at the same time ensure the cleaning effect and prevent the material from spilling from the belt edge.

[0039] As an embodiment of this utility model, the second cleaner 800 further includes a second scraper 8001. The top surface of the second scraper 8001 is configured as a double-sided scraping nozzle 8002, which can simultaneously clean both sides of the bottom surface of the belt conveyor body 100. Compared with a single-sided scraping nozzle, it can more comprehensively remove the material adhering to the bottom surface of the belt, improve cleaning efficiency, ensure the cleanliness of the bottom surface of the belt, and avoid material residue affecting the operation of the belt.

[0040] As one embodiment of this utility model, the first scraper 7001 and the second scraper 8001 are further made of polyurethane. Polyurethane has good wear resistance, which can maintain the shape and scraping performance of the scrapers during long-term cleaning work, reducing the frequency of replacement.
