Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation equipment, in particular to a self-adjusting roller coal cleaning device. Background Art

[0002] During the coal mining process, transportation equipment is needed to transport coal blocks in the mine. Generally, the transportation equipment uses a circulating conveyor belt. Located in the coal mining area inside the coal mine, the end of the conveyor belt is wound around a roller, and the roller is rotatably arranged on a bracket. Since in the coal mining environment, the circumferential surface of the roller often carries and adheres to coal powder or coal blocks, etc. The end of the conveyor belt is roughly semi-surrounded outside the roller. The coal powder or coal blocks accumulated on the outer surface of the roller contact the inner side of the conveyor belt, which easily causes the conveyor belt to shift or cause severe shaking and deformation of the conveyor belt, etc., affecting the normal transportation process and even causing equipment damage. Therefore, it is necessary to scrape and clean the surface of the roller. In the existing roller coal scraping device, generally, a compression spring is used to press the coal scraping plate forcefully against the surface of the roller, and the selection of the compression spring is crucial. When the pressure is too high, although the coal scraping and cleaning force on the roller is relatively high, the coal scraping plate wears severely, the service life is shortened, and the surface of the roller is easily damaged. At the same time, as the end of the coal scraping plate continues to wear, the coal scraping plate becomes shorter, and the compression spring becomes longer to keep the coal scraping plate pressed against the roller. However, after the compression spring becomes longer, the pressure exerted on the coal scraping plate becomes smaller, and the coal scraping force weakens, affecting the cleaning effect. When installing the compression spring, it is necessary to prevent coal blocks from blocking the compression spring, and the installation structure is relatively complex.

[0041] Such as Figures 1-7As shown in the figure, the self-adjusting roller coal cleaning device is used to be arranged on the support 1 and beside the roller 2, and includes: mounting frames 3, there are two mounting frames 3, and the two mounting frames 3 are used to be arranged relatively on the left and right sides of the support 1. The upper end of the mounting frame 3 has an inclined guiding surface 3011, and the side of the inclined guiding surface 3011 close to the roller 2 is lower than the side far from the roller; the coal collecting box 4 has coal discharging ports 405 on both the left and right sides and a coal inlet 406 on the upper side. The left and right sides of the coal collecting box 4 are respectively arranged to slide on the inclined guiding surfaces 3011 on the left and right sides. There is a coal dropping interval 407 between the coal discharging port 405 and the side of the adjacent support 1; the coal scraping plate 5 is arranged at the rear side of the coal collecting box 4. The coal scraping plate 5 is inclined and has a coal scraping end 501. The coal scraping end 501 is located at the higher end of the coal scraping plate 5, and the coal scraping end 501 is used to abut against the circumferential surface of the roller 2; the coal pushing plate 6 is arranged to move in the left-right direction in the coal collecting box 4, and after the coal pushing plate 6 moves, it approaches or moves away from the coal discharging port 405.

[0042] During use, the mounting frame 3 can be welded to the support 1. The coal collecting box 4 is beside the roller 2. The coal scraping plate 5 abuts against the upper half of the circumferential surface of the roller 2. Under its own weight, the coal collecting box 4 slides along the inclined guiding surface 3011 to the lower side. The roller 2 is located on the lower side of the inclined guiding surface 3011. The coal scraping end 501 presses down and abuts against the circumferential surface of the roller 2. The coal scraping end 501 cleans the coal lumps and other sundries on the roller 2. The sundries enter the coal collecting box 4 through the coal inlet 406. There is a coal dropping interval 407 between the coal discharging port 405 and the side of the adjacent support 1. There can be coal dropping intervals 407 on both the left and right sides of the coal collecting box 4. The coal pushing plate 6 pushes the coal lumps and the like to the coal discharging port 405, and then they fall to both sides through the coal dropping interval 407 and are located outside the conveyor belt.

[0043] Furthermore, the mounting frame 3 includes two vertical support plates 301. One side of the vertical support plate 301 is used to be arranged on the support 1, and the other side is inclined relative to the coal discharging port 405 to increase the interval between the lower part of the vertical support plate 301 and the coal discharging port 405. The upper end of the vertical support plate 301 has a limiting groove 3012. The bottom surface of the limiting groove 3012 is a part of the inclined guiding surface 3011. The front limiting groove 3012 is higher than the rear limiting groove 3012; both the left and right sides of the coal collecting box 4 include guiding plates 408, and the guiding plates 408 are slidably arranged in the limiting grooves 3012.

[0044] During use, in the mounting frame 3, two vertical support plates 301 can be set and welded to the support 1. The two vertical support plates 301 are located in the coal dropping interval 407 and are at different heights. The upper ends of the vertical support plates 301 are provided with limiting grooves 3012. The limiting grooves 3012 are located on the front and rear sides of the guiding plates 408. The side of the vertical support plate 301 opposite to the coal discharging port 405 is inclined, and the interval between the vertical support plate 301 and the coal discharging port 405 gradually increases from top to bottom, which is convenient for discharging coal lumps. The guiding plates 408 slide inclinedly in the limiting grooves 3012, and the movement in the left-right direction is restricted.

[0045] Furthermore, the coal receiving box 4 further includes a bottom plate 401, a front plate 402 and a rear plate 403. The front plate 402 is arranged at the front end of the bottom plate 401, the rear plate 403 is arranged at the rear end of the bottom plate 401, and the coal scraping plate 5 is arranged on the rear plate 403; it further includes: a reinforcing plate 404, arranged at the rear side of the rear plate 403.

[0046] During use, the coal receiving box 4 can be installed on the mounting frame 3 from above. The guiding plate 408 is on the mounting frame 3. At the same time, the coal scraping end 501 can fall on the upper half side of the roller. The thickness of the coal scraping plate 5 is relatively thin, which is convenient for coal scraping. The arrangement of the reinforcing plate 404 can improve the strength of the coal scraping plate 5. The guiding plate 408 is arranged at the ends of the front plate 402 and the rear plate 403, and at the same time forms a coal discharging port 405. The guiding plate 408 is arranged substantially parallel to the inclined guiding surface 3011.

[0047] Furthermore, it further includes: a connecting screw 601, passing through the coal pushing plate 6; two locking nuts 602, respectively threadedly connected to the left and right sides of the connecting screw 601; a coal cleaning pull pipe 603, passing through the support 1, one end connected to the connecting screw 601, and the other end located outside the support 1; two limiting rods 604, both inserted on the coal cleaning pull pipe 603, one of the limiting rods 604 is located outside the support 1, and the other limiting rod 604 is located on the side of the coal cleaning pull pipe 603 close to the coal pushing plate 6.

[0048] During use, the locking nuts 602 are located on the left and right sides of the coal pushing plate 6, locking the connecting screw 601 on the coal pushing plate 6. The coal cleaning pull pipe 603 can be a tubular structure, one end can be inserted or threadedly connected to the end of the connecting screw 601, and the other end extends outside the support 1, which is convenient for manually operating and pulling the coal cleaning pull pipe 603, thereby driving the coal pushing plate 6 to move. The arrangement of the limiting rods 604 can limit the left and right displacement of the coal cleaning pull pipe 603, prevent the coal pushing plate 6 from moving out of the coal receiving box 4, and at the same time can know whether the coal pushing plate 6 has moved in place. After the limiting rod 604 moves, it abuts against or moves away from the side of the support 1.

[0049] Furthermore, it further includes: an extension plate 7, arranged at the rear end of the coal receiving box 4; a coal receiving plate 8, arranged at the rear end of the extension plate 7 and below the coal scraping plate 5. There is a gap between the upper end of the coal receiving plate 8 and the circumferential surface of the roller 2. The coal receiving plate 8, the extension plate 7 and the rear plate 403 form a coal receiving area 9.

[0050] During use, the coal receiving area 9 can receive coal powder, coal blocks, etc. that leak from the coal scraping end 501. When there is wear, vibration, or incomplete scraping, some coal powder or coal blocks will not be scraped off by the coal scraping end 501, but will fall from the roller 2 after passing through the coal scraping end 501. At this time, the coal receiving area 9 can collect them to avoid affecting the conveyor belt.

[0051] Furthermore, the coal receiving plate 8 has a fixing portion 801 and a rubber portion 802. The rubber portion 802 is inserted and arranged at the upper end of the fixing portion 801. There is a gap between the upper end of the rubber portion 802 and the circumferential surface of the roller 2. The fixing portion 801 is arranged on the extension plate 7.

[0052] During use, to reduce the assembly requirements and reduce impacts, etc., the coal scraping end 501 contacts the roller 2 to clean the coal. There is a gap between the end of the coal receiving plate 8 and the roller, and it approaches the roller 2 through the rubber portion 802. When there is a large deviation in assembly, the roller 2 contacts the rubber, and the wear of the roller 2 is small. The rubber can adapt to the wear by itself, reducing the impact between hard objects.

[0053] Furthermore, there are several coal scraping plates 5. The several coal scraping plates 5 are arranged in an array in the left - right direction on the rear plate 403 in sequence. The coal scraping plates 5 are connected to the rear plate 403 by tightening bolts.

[0054] During use, the coal scraping plates 5 are detachably installed on the rear plate 403 by tightening bolts, which is convenient for replacing the worn coal scraping plates 5, and the replaced parts are small. And multiple coal scraping plates 5 are arranged side by side. For a single coal scraping plate 5 with relatively large local wear, it can be replaced separately.

[0055] Furthermore, the upper part of the rear plate 403 has an installation portion 4031. The coal scraping plate 5 has a bending portion 502. The bending portion 502 is located on the side of the coal scraping plate 5 opposite to the coal scraping end 501. The bending portion 502 is arranged on the installation portion 4031 and is connected by tightening bolts.

[0056] During use, the installation portion 4031 at the upper part of the rear plate 403 can be formed by bending, which can enhance the strength. The bending portion 502 of the coal scraping plate 5 is formed by bending and can be a right - angle bend, which can enhance the strength of the coal scraping plate 5. At the same time, the bending portion 502 and the installation portion 4031 are adapted for installation. The connection structure of the tightening bolts is an existing technology, and tightening connection can be carried out by opening through - holes or threaded holes.

[0057] Furthermore, the lower end of the rear plate 403 has a through - groove 4032. The through - groove 4032 communicates the coal receiving area 9 and the inside of the coal collecting box 4.

[0058] During use, after the through - groove 4032 communicates the coal receiving area 9 and the inside of the coal collecting box 4, after the coal pushing plate 6 clears the coal blocks inside the coal collecting box 4, some pulverized coal, coal blocks, etc. collected in the coal receiving area 9 can enter the coal collecting box 4 through the through - groove 4032, and then be pushed out by the coal pushing plate 6, which can extend the cleaning cycle of the coal receiving area 9 alone. The bottom plate 401 of the coal collecting box 4 can be inclined to facilitate the sliding of the pulverized coal in the coal receiving area 9 into the coal collecting box 4. The pulverized coal collected in the coal receiving area 9 is relatively less, and the cleaning cycle is longer than that of the coal collecting box 4.

[0059] It can be understood that the present utility model is described by way of some embodiments. Those skilled in the art will appreciate that, without departing from the spirit and scope of the present utility model, various changes or equivalent substitutions can be made to these features and embodiments. Additionally, under the teachings of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
