Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker-reclaimer technology, specifically to a bucket wheel cleaning device for a stacker-reclaimer. Background Technology
[0002] Bucket wheel stacker-reclaimers are large-scale, high-efficiency, and continuously operating bulk material handling equipment widely used in ports, power plants, steel mills, and other industrial sites requiring large-scale processing of bulk materials such as coal, ore, and sand. Integrating stacking and reclaiming functions, they use rotating bucket wheels to excavate materials, and work with cantilever belt conveyors to transport and store them. They feature high automation, high operating efficiency, and low operating costs, making them one of the core pieces of equipment in modern bulk material handling systems.
[0003] The equipment mainly consists of a bucket wheel mechanism, a slewing platform, a pitching device, a traveling mechanism, a cantilever conveyor belt, and a tail car. The bucket wheel mechanism is the core component, consisting of multiple buckets arranged in a wheel shape, which dig materials by rotating. The slewing platform supports 360° rotation of the superstructure, achieving full coverage of the working range. The pitching device adjusts the cantilever angle to adapt to different stacking heights and material removal depths. The traveling mechanism mostly uses rails or tracks to ensure flexible movement of the entire machine. During operation, in material removal mode, the bucket wheel digs materials to the cantilever conveyor belt, which then transfers them to the main conveying system. In material stacking mode, the cantilever conveyor belt throws incoming materials to designated stockpiles, forming a regular material yard in conjunction with the traveling and slewing actions.
[0004] Advanced models are equipped with a PLC automatic control system, enabling programmable unmanned operation. They precisely control the shape of material piles through laser scanning or 3D modeling and feature functions such as flow monitoring and fault diagnosis. A single machine can handle 1000-6000 tons per hour, adapting to ambient temperatures from -30℃ to 50℃. Special designs allow them to handle highly corrosive or flammable and explosive materials. Compared to traditional loaders, energy consumption is reduced by approximately 40%, and dust pollution is significantly decreased. With the development of intelligent technologies, 5G remote control and digital twins are driving the equipment towards greater safety and efficiency, making it a crucial support for modern smart logistics and green mining construction.
[0005] During long-term operation, existing stacker-reclaimers tend to accumulate a large amount of material on the inner wall of the hopper, especially bulk materials with high moisture content or high viscosity (such as coal and mineral powder). This material gradually accumulates and hardens on the hopper surface. These deposits not only reduce the effective volume of the hopper and decrease feeding efficiency, but may also cause uneven material distribution, leading to uneven loading when the bucket wheel rotates, affecting the stability of the equipment. Therefore, it takes a long time to clean the hopper. Furthermore, since existing hoppers are usually directly fixed to the bucket wheel structure, their internal space is narrow, and the gap between the bucket wheel and the hopper is limited, making it difficult for personnel or machinery to enter during cleaning operations. Relying on inefficient methods such as manual knocking and high-pressure water jet washing is both time-consuming and poses safety hazards. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content
[0006] 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.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a bucket wheel cleaning device for a stacker-reclaimer, comprising a bucket wheel body, with first mounting plates on both sides of the bucket wheel body, the first mounting plates being evenly distributed sequentially on both sides, a first motor on one side of the first mounting plate, and a mounting frame on one side of the bucket wheel body, a rotating roller on the inner side of the mounting frame, and cleaning scrapers on the outer side of the rotating roller, the cleaning scrapers being evenly distributed on one side. Through a cleaning mechanism, the cleaning scrapers and side cleaning plates can rotate around the rotating roller as the center, allowing multiple cleaning scrapers and side cleaning plates to quickly scrape off and clean the material adhering to the inside of the hopper, improving the cleaning efficiency of the material adhering to the inside of the hopper. Through a spacing adjustment mechanism, when it is necessary to clean the material adhering to the inside of the hopper, the hopper can be moved away from the bucket wheel body, leaving sufficient space between the hopper and the bucket wheel body, so that the cleaning mechanism has sufficient space to clean the hopper.
[0008] Preferably, one end of the power output shaft of the first motor passes through the first mounting plate and extends to the other side of the first mounting plate, and one end of the power output shaft of the first motor is connected to a threaded rod, and the main structure is installed through the first mounting plate.

[0010] Preferably, a sleeve rod is provided on one side of the first mounting plate. One end of the sleeve rod passes through the threaded sleeve and extends into the interior of the threaded sleeve. A second mounting plate is connected to one end of both the threaded sleeve and the telescopic limiting rod. The sleeve rod blocks the threaded rod, preventing impurities from entering the thread groove of the threaded rod.
[0011] Preferably, a hopper is provided between the inner sides of the second mounting plates on both sides.
[0012] Preferably, lateral cleaning plates are provided on both sides of the rotating roller, and both the cleaning scraper and the lateral cleaning plates are in contact with the inner wall of the hopper, so that the material on the side wall of the hopper is cleaned by the lateral cleaning plates.

One end of the power output shaft of the second motor passes through the mounting frame and extends to the other side of the mounting frame. The power output shaft of the second motor is connected to the rotating roller. The rotating roller is driven by the second motor to rotate, so that the cleaning mechanism cleans the material in the hopper.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. The bucket wheel cleaning device of this stacker-reclaimer, through the cleaning mechanism, enables the cleaning scraper and side cleaning plate to rotate around the rotating roller as the center, so that multiple cleaning scrapers and side cleaning plates can quickly scrape off and clean the material adhering to the inside of the bucket, thereby improving the cleaning efficiency of the material adhering to the inside of the bucket.
[0016] 2.

Detailed Implementation
[0022] 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.
[0023] Example 1: Please refer to again Figure 1-4 This utility model provides a bucket wheel cleaning device for a stacker-reclaimer, including a bucket wheel body 100. First mounting plates 110 are provided on both sides of the bucket wheel body 100, and the first mounting plates 110 are evenly distributed sequentially on both sides. A first motor 120 is provided on one side of the first mounting plate 110. One end of the power output shaft of the first motor 120 passes through the first mounting plate 110 and extends to the other side of the first mounting plate 110. A threaded rod 121 is connected to one end of the power output shaft of the first motor 120. A threaded sleeve 122 is connected to the outer side of the threaded rod 121. A telescopic limiting rod 130 is provided on one side of the other first mounting plate 110. A sleeve rod 140 is provided on one side of one first mounting plate 110. One end of the sleeve rod 140 passes through the threaded sleeve 122 and extends into the interior of the threaded sleeve 122. A second mounting plate 150 is connected to one end of both the threaded sleeve 122 and the telescopic limiting rod 130. A hopper 160 is provided between the inner sides of the two second mounting plates 150.
[0024] Specifically, when it is necessary to adjust the distance between the hopper 160 and the bucket wheel body 100, the first motor 120 is started to drive the threaded rod 121 to rotate, causing the threaded sleeve 122 installed on the threaded rod 121 to move with the rotation of the threaded rod 121, causing the second mounting plate 150 installed on the threaded sleeve 122 to move, and causing the hopper 160 connected to the second mounting plate 150 to move, thereby adjusting the distance between the hopper 160 and the bucket wheel. At the same time, the telescopic limit rod 130 limits the movement of the hopper 160. After the threaded rod 121 moves, the sleeve rod 140 installed on the first mounting plate 110 shields and protects the part of the threaded rod 121 exposed from the threaded sleeve 122, preventing external impurities from entering the thread groove of the threaded rod 121 and affecting the normal operation of the threaded rod 121.
[0025] Example 2: Please refer to again Figure 1-4 A mounting frame 200 is provided on one side of the bucket wheel body 100. A rotating roller 210 is provided on the inner side of the mounting frame 200. A cleaning scraper 220 is provided on the outer side of the rotating roller 210. The cleaning scrapers 220 are evenly distributed on one side. Lateral cleaning plates 230 are provided on both sides of the rotating roller 210. Both the cleaning scraper 220 and the lateral cleaning plates 230 are in contact with the inner wall of the hopper 160. A second motor 240 is provided on one side of the mounting frame 200. One end of the power output shaft of the second motor 240 passes through the mounting frame 200 and extends to the other side of the mounting frame 200. One end of the power output shaft of the second motor 240 is connected to the rotating roller 210.
[0026] Specifically, after the hopper 160 moves to the outside, the rotating roller 210 is placed inside the hopper 160, and then the rotating roller 210 is driven to rotate by starting the second motor 240. After the rotating roller 210 rotates, the cleaning scraper 220 and the side cleaning plate 230 installed on the rotating roller 210 clean the material attached to the inside and side wall of the hopper 160.
[0027] Working principle: When it is necessary to adjust the distance between the hopper 160 and the bucket wheel body 100, the first motor 120 is started to drive the threaded rod 121 to rotate, causing the threaded sleeve 122 installed on the threaded rod 121 to move with the rotation of the threaded rod 121, causing the second mounting plate 150 installed on the threaded sleeve 122 to move, and causing the hopper 160 connected to the second mounting plate 150 to move, thereby adjusting the distance between the hopper 160 and the bucket wheel. At the same time, the telescopic limit rod 130 limits the movement of the hopper 160. After the threaded rod 121 moves, the sleeve rod 140 installed on the first mounting plate 110 shields and protects the part of the threaded rod 121 exposed from the threaded sleeve 122, preventing external impurities from entering the thread groove of the threaded rod 121 and affecting the normal operation of the threaded rod 121.
[0028] After the hopper 160 moves to the outside, the rotating roller 210 is placed inside the hopper 160, and then the rotating roller 210 is driven to rotate by starting the second motor 240. After the rotating roller 210 rotates, the cleaning scraper 220 and the side cleaning plate 230 installed on the rotating roller 210 clean the material attached to the inside and side wall of the hopper 160.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
