Description

Technical Field

[0001] This invention belongs to the field of mining equipment, and specifically relates to a device for collecting residual mineral powder from a conveyor belt. Background Technology

[0002] During conveyor belt transport, mineral powder easily adheres to the belt. Although some conveyor belts have scraper mechanisms at the ends to clean the adhering mineral powder, the fine particles are difficult to remove completely, leading to an accumulation of mineral powder at the bottom of the conveyor during transport. In existing technologies, to prevent waste, a collection trough is typically installed at the bottom of the conveyor to collect the mineral powder. The powder is then flushed into a sedimentation tank for recycling. While water flushing is more time- and labor-saving than manual cleaning of the trough, some powder still adheres to it, especially during long-distance transport. During the process, the trough is long, and water flushing can only clean the mineral powder at the points where the water flow impacts. The remaining parts can only be cleaned by gravity flow. However, gravity flow cannot guarantee the cleaning of mineral powder throughout the entire trough, especially at the sides, where gravity flow is difficult to clean. If the entire trough is flushed and cleaned, water resources are wasted in long troughs, and the labor intensity is also high. Furthermore, during inclined lifting and conveying, if water flushing or sweeping is used to collect mineral powder from the bottom to the top, it is difficult to sweep and collect it from the bottom before conveying it by the conveyor belt, which is time-consuming and labor-intensive. When using water flushing, sedimentation treatment is also required, which is quite inconvenient. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To overcome the shortcomings of existing technologies, a residual mineral powder collection device for conveyor belts is proposed. This addresses the issue that in existing technologies, mineral powder adheres to the channel, especially during long-distance conveying. In long channels, water flushing can only clean the powder at the points of impact, while the remaining areas require gravity flow for cleaning. However, gravity flow cannot guarantee the cleaning of the entire channel, particularly the sides, where gravity flow is insufficient. Flushing the entire channel is wasteful of water and labor-intensive in long channels. Furthermore, during inclined lifting conveying, collecting mineral powder from the bottom up is difficult during water flushing or sweeping, requiring collection from the bottom before conveying via the conveyor belt – time-consuming and labor-intensive. Water flushing also necessitates sedimentation, adding to the inconvenience.

[0005] (II) Technical Solution

[0006] This invention is achieved through the following technical solution: This invention proposes a conveyor belt residual mineral powder collection device, the structure of which includes a conveyor belt and a collection device, wherein the conveyor belt is assembled on the collection device;

[0007] The collection device includes a base plate, a scraping device, side plates, a motor, and a gearbox. Two side plates are provided, and the two side plates are fixedly connected to the base plate in a U-shape. The conveyor belt is mounted above and between the two side plates. A scraping device is installed between the conveyor belt and the base plate. The base plate is used to collect residual mineral powder from the conveyor belt, and the scraping device is used to push and scrape the mineral powder collected by the base plate to a designated location. A gearbox is mounted on the side plates, and the gearbox is used to drive the conveyor belt and the scraping device to rotate. The motor drives the gearbox.

[0008] The cleaning device includes a circulation structure, a scraper connector, and a scraper. The circulation structure is mounted below the two side plates and is located between the conveyor belt and the bottom plate. The scraper connector is hinged to the circulation structure, and a scraper is fixed to the scraper connector away from the circulation structure. The circulation structure is used for driving and limiting the cyclic movement of the scraper.

[0009] The circulation structure includes a circulation belt, guide rails, assembly slots, and linkage rollers. Assembly slots are provided on the lower sides of adjacent sides of the two side plates. There are two or more linkage rollers, which are assembled within the assembly slots of the two side plates. The circulation belt is mounted around the two or more linkage rollers. Guide rails are also fixed within the assembly slots of the two side plates. The guide rails are mounted along the periphery of the circulation belt, and the shortest distances from the guide rails to the circulation belt are all the same. The motor drives the linkage rollers to rotate via a gearbox. The scraper connector, at its end away from the scraper, is hinged to the circulation belt, and the side end of the scraper connector is wrapped around the guide rail.

[0010] The scraper connector includes a connecting plate, a movable wheel, a wheel axle, a hinge joint, and a hinge shaft. The hinge joint is fixed on the side of the circulating strip away from the linkage roller. The connecting plate is a shaped plate. Movable wheels are assembled inside the two sides of the opening of the connecting plate through the wheel axle. The opening end of the connecting plate is covered and assembled on the guide rail through the movable wheels. One side of the connecting plate is hinged to the hinge joint through the hinge shaft. The side of the connecting plate away from the hinge joint is fixedly connected to the scraper.

[0011] Furthermore, the scraper connector, the circulating strip, and the guide rail are all located within the assembly groove.

[0012] Furthermore, the scraper includes a limiting groove, a compression spring, an outer scraper, an inner scraper, a telescopic groove, a limiting rod, a limiting plate, and a scraper assembly plate. Limiting grooves are also provided around the assembly grooves of the two side plates. The shortest distances between the limiting grooves and the assembly grooves are all the same. Scraper connectors assembled at the same position on the two side plates are fixedly connected to the same scraper assembly plate. One end of the outer scraper is locked to the scraper assembly plate. A telescopic groove is provided inside the outer scraper on the side away from the scraper assembly plate. The limiting plate is assembled in the telescopic groove. A compression spring is assembled between the limiting plate and the outer scraper on the side adjacent to the scraper connector. The side of the limiting plate away from the scraper connector is fixedly connected to one end of the inner scraper. The end of the inner scraper away from the limiting plate passes through the outer scraper. A limiting rod is fixedly assembled on the side of the inner scraper adjacent to the limiting groove. The limiting rod is located on the side adjacent to the limiting plate. The side of the inner scraper adjacent to the limiting groove passes through the outer scraper and fits against the side plate. The limiting rod is located within the limiting groove.

[0013] Furthermore, the limiting groove includes a straight section, a first end, and a second end. Each of the straight section, the first end, and the second end has two locations. The two straight sections are arranged parallel to the upper and lower ends of the assembly groove. The two ends of the straight section parallel to the upper part of the assembly groove are connected to one end of the two first ends. The other ends of the two first ends are connected to the two ends of the straight section parallel to the lower part of the assembly groove through the two second ends. The sides of the first end and the second end adjacent to the assembly groove are parallel to the assembly groove. The distance between the first end and the assembly groove from the side away from the assembly groove gradually decreases from the straight section to the second end. The distance between the second end and the assembly groove from the side away from the assembly groove gradually decreases from the straight section to the first end.

[0014] Furthermore, a wear detection device is also provided in the limiting groove of the side plate, and the wear detection device detects the position of the inner scraper by the position of the limiting rod.

[0015] Furthermore, the wear detection device includes a push switch, an assembly bottom ring, a combination block, and an assembly top ring. The push switch is a normally open switch that closes upon push. The push switch and the combination block can be joined vertically. The push end of the push switch and the combination block penetrate the side plate and are flush with the side of the limiting groove away from the inner scraper. The side of the push switch and the combination block away from the limiting groove is covered and fixed by the assembly bottom ring and the assembly top ring. The assembly bottom ring and the assembly top ring are embedded and locked to the side plate.

[0016] Furthermore, the inner scraper side end is attached to the two side plates.

[0017] (III) Beneficial Effects

[0018] One of the above technical solutions has the following advantages or beneficial effects:

[0019] To address the issue that existing technologies often result in mineral powder adhering to the channel, especially during long-distance transport, where the channel is long and water flushing only cleans the powder at the point of impact, leaving the remaining areas uncleaned by gravity flow, which cannot guarantee complete cleaning of the entire channel, particularly along the sides, water flow struggles to remove the powder. Furthermore, flushing the entire channel is wasteful of water and labor-intensive in long transport sections. During inclined conveying, collecting powder from the bottom up is difficult, requiring collection from the bottom before conveying via the conveyor belt, which is time-consuming and labor-intensive. Water flushing also necessitates sedimentation, adding to the inconvenience. Therefore, a collection device with a scraping mechanism is proposed. This scraping mechanism uses a circulating belt for cyclic scraping, combined with a track and a retractable... The scraper structure ensures stability during scraping, while the limiting groove restricts the scraper's extension and retraction trajectory, allowing for better contact between the scraper and the base plate. This facilitates cleaning of the conveyor belt bottom when circulating to the top and reduces the risk of collisions caused by scraping beyond the conveyor belt's range. Simultaneously, the device collects residual mineral powder from the conveyor belt and scrapes it towards the destination, avoiding the inconvenience of subsequent sedimentation or transport. The circulating strip is embedded in the side plate, reducing the amount of mineral powder adhering to the scraping device when it falls from the conveyor belt. The scraper, with a width equal to the entire collection channel, ensures thorough cleaning of the entire collection channel. The limiting groove also houses a wear detection device, whose position can be adjusted through combinations. The device triggers a warning when the inner scraper wears to a certain extent, facilitating timely replacement of the inner scraper. Attached Figure Description

The guide rail b1b is mounted along the periphery of the circulation strip b1a, and all shortest distances between the guide rail b1b and the circulation strip b1a are the same. The motor d drives the linkage roller b1d to rotate via a gearbox e. The end of the scraper connector b2 away from the scraper b3 is hinged to the circulation strip b1a, and the side end of the scraper connector b2 is wrapped around the guide rail b1b.

[0034] The scraper connector b2, the circulating strip b1a, and the guide rail b1b are all located within the assembly groove b1c.

[0035] The scraper connector b2 includes a connecting plate b2a, a movable wheel b2b, a wheel axle b2c, a hinge joint b2d, and a hinge shaft b2e. The hinge joint b2d is fixed to the side of the circulating belt b1a away from the linkage roller b1d. The connecting plate b2a is a C-shaped plate. Movable wheels b2b are assembled inside the two sides of the opening of the connecting plate b2a through the wheel axle b2c. The opening end of the connecting plate b2a is covered and assembled on the guide rail b1b through the movable wheels b2b. One side of the connecting plate b2a is hinged to the hinge joint b2d through the hinge shaft b2e. The side of the connecting plate b2a away from the hinge joint b2d is fixedly connected to the scraper b3.

A limiting groove b3a is also provided around the assembly groove b1c of the two side plates c. The shortest distances from the limiting groove b3a to the assembly groove b1c are all the same. Scraper connectors b2 assembled at the same position on the two side plates c are fixedly connected to the same scraper assembly plate b3h. One end of the outer scraper b3c is locked to the scraper assembly plate b3h. A telescopic groove b3e is provided inside the outer scraper b3c on the side away from the scraper assembly plate b3h. The limiting plate b3g is assembled in the telescopic groove b3e. A compression spring b3b is assembled between the side of the limiting plate b3g adjacent to the scraper connector b2 and the outer scraper b3c. The side of the limiting plate b3g away from the scraper connector b2 is fixedly connected to one end of the inner scraper b3d. The end of the inner scraper b3d away from the limiting plate b3g passes through the outer scraper b3c. A limiting rod b3f is fixedly assembled on the side of the inner scraper b3d adjacent to the limiting groove b3a. The limiting rod b3f is located on the side adjacent to the limiting plate b3g. The side of the inner scraper b3d adjacent to the limiting groove b3a passes through the outer scraper b3c and fits against the side plate c. The limiting rod b3f is located in the limiting groove b3a.

[0037] The limiting groove b3a includes a straight section b3a1, a first end b3a2, and a second end b3a3. Each of the straight section b3a1, the first end b3a2, and the second end b3a3 has two locations. The two locations of the straight section b3a1 are parallel to the upper and lower ends of the assembly groove b1c. The two ends of the straight section b3a1 parallel to the upper part of the assembly groove b1c are connected to one end of each of the two first ends b3a2. The other ends of the two first ends b3a2 are connected to the two second ends b3a3. a3 is connected to both ends of a straight section b3a1 that is parallel to the bottom of the assembly groove b1c. The first end b3a2 and the second end b3a3 are parallel to the assembly groove b1c on the side adjacent to the assembly groove b1c. The distance between the first end b3a2 and the assembly groove b1c on the side away from the assembly groove b1c gradually decreases from the straight section b3a1 to the second end b3a3. The distance between the second end b3a3 and the assembly groove b1c on the side away from the assembly groove b1c gradually decreases from the straight section b3a1 to the first end b3a2.

[0038] The side plate c is provided with a wear detection device f in the limiting groove b3a. The wear detection device f detects the position of the inner scraper b3d by the position of the limiting rod b3f.

[0039] The wear detection device f includes a push switch f1, an assembly bottom ring f2, a combination block f3, and an assembly top ring f4. The push switch f1 is a normally open switch that closes upon push. The push switch f1 and the combination block f3 can be spliced ​​together vertically. The push end of the push switch f1 and the combination block f3 penetrate the side plate c and are flush with the side of the limiting groove b3a away from the inner scraper b3d. The side of the push switch f1 and the combination block f3 away from the limiting groove b3a is covered and fixed by the assembly bottom ring f2 and the assembly top ring f4. The assembly bottom ring f2 and the assembly top ring f4 are embedded and locked to the side plate c.

[0040] The inner scraper b3d side end is attached to the two side plates c.

[0041] The gearbox e drives the conveyor belt 1 and the circulating structure b1 to rotate at different speeds.

[0042] The circulating strip b1a can be made of rubber, metal, or toothed material, or it can be a chain.

[0043] Implementation Plan: During operation, residual mineral powder on conveyor belt 1 falls into the channel formed by bottom plate a and side plate c. Simultaneously, motor d, driving conveyor belt 1 via gearbox e, also drives the linkage roller b1d of the circulation structure b1 to rotate synchronously. The linkage roller b1d drives the circulating strips b1a located in the assembly slots b1c of side plate c to circulate, causing the circulating strips b1a to move through the hinge joint b2d and drive the connecting plate b2a to move, making the two side plates identical. The connecting plate b2a at the position will synchronously drive the assembled scraper assembly plate b3h to move. The outer scraper b3c assembled on the scraper assembly plate b3h will drive the inner scraper b3d to move together. The limiting plate b3g connected to the inner scraper b3d allows it to extend and retract within the telescopic groove b3e of the outer scraper b3c. The pressure of the compression spring b3b allows the inner scraper b3d to better fit the cleaning area. At the same time, the limiting rod b3f on the side of the inner scraper b3d, combined with the limiting groove b3a of the side plate c, allows the inner scraper b3d to move. During cyclic cleaning, scraper b3d can also extend and retract according to the braking trajectory. Through the structure of the limiting groove b3a, the inner scraper b3d can ensure its feed retraction when moving to the inlet / outlet, reducing the risk of over-traffic collisions. When the inner scraper b3d moves to the top, it can also scrape the bottom of the conveyor belt 1 through the differential speed operation of the gearbox e, further reducing the adhesion of mineral powder on the conveyor belt. Meanwhile, the moving wheel b2b connecting plate b2a slides on the guide rail b1b... The movement of the connecting plate b2a can better ensure the stability of the movement of the inner scraper b3d and the stable movement of the inner scraper b3d during cleaning. Combined with the fact that the side end of the inner scraper b3d is attached to the two side plates c, the inner scraper b3d can take care of the entire collection channel formed by the bottom plate a and the side plates c during cleaning. This can ensure the overall cleaning of the collection channel, freeing the device from water flushing. It can also save resources and avoid waste while ensuring the cleaning and transportation of collected mineral powder. At the same time, the device does not require manual operation, which can reduce the labor intensity of the workers.

[0044] Furthermore, the device can collect residual mineral powder from conveyor belt 1 and scrape the collected mineral powder towards the destination in the direction of conveyor belt 1, avoiding the inconvenience of sedimentation or transportation after collection. The circulating strip b1a of the device is embedded in the side plate c, which can reduce the adhesion of mineral powder from conveyor belt 1 to the scraping device b when it falls. A wear detection device f is also provided in the limiting groove b3a of the device. The wear detection device f can be unlocked and separated by assembling the bottom ring f2 and the top ring f4. Then, the height of the combination switch f1 can be adjusted by the combination block f3, so that the wear detection device f can be easily adjusted for detection position. After combination, it can be locked by assembling the bottom ring f2 and the top ring f4. When the inner scraper b3d of the collecting device 2 wears to a certain extent, the limiting rod b3f of the inner scraper b3d will press the normally open push switch f1 to close during the circulation process, triggering the push switch f1 to provide a prompt, so as to facilitate timely replacement of the inner scraper b3d.
