Description

Technical Field

[0001] The present invention relates to the technical field of coal mine conveyors, and particularly to an efficient cleaning device for a coal mine belt conveyor. Background Art

[0002] The working environment of coal mines is harsh, and a large amount of mineral powder is extremely likely to adhere to the surface of the conveyor belt. In addition, the conveyor belt continuously bears weight and bends frequently. Over time, not only is the surface uneven, but it is also covered with stubborn stains.

[0003] The environment underground in coal mines is dusty, and a huge amount of mineral powder is generated during mining, loading and unloading and other links. They inevitably adhere to the conveyor belt. As the conveyor belt continuously circulates, the mineral powder first covers in a thin layer, and then under the action of humidity and pressure, it gradually compacts and cakes, deeply embedding into the texture gaps on the surface of the conveyor belt. Existing cleaning devices for coal mine conveyor belts rely on simple scrapers and brushes, and most can only remove the outermost loose mineral powder. They have little effect on the caked stubborn stains, are not easy to scrape off the stubborn mineral powder, and often cause the scraper blades to wear rapidly during the scraping operation, and are extremely likely to damage the surface layer of the conveyor belt, resulting in a poor cleaning effect on the surface of the coal mine conveyor belt. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problems in the background art and provide an efficient cleaning device for a coal mine belt conveyor. When the conveyor belt in the coal mine conveyor maintains flatness, the efficient cleaning device can not only deeply clean the mineral powder adhering to the conveyor belt and improve the cleaning effect of the mineral powder, but also timely squeeze and process the water stains on the conveyor belt to enhance the long-term cleanliness of the conveyor belt.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention provides an efficient cleaning device for a coal mine belt conveyor, which applies stable extrusion downward to the conveyor belt through the crawler belt, so that the conveyor belt is always kept taut, effectively avoiding uneven conditions, and at the same time, the scraper plate is used to scrape off the mineral powder attached to the surface of the conveyor belt. At the same time, under the extrusion of the crawler belt, the conveyor belt and the cleaning roller are closely fitted, and as the conveyor belt is driven, the cleaning roller is driven to rotate, thereby completing the cleaning work of the conveyor belt.

[0018] 2. The present invention provides a high-efficiency cleaning device for a coal mine belt conveyor. The external water pump operates continuously to draw water and introduce it into a water spray pipe. With the help of the spraying effect of the water spray pipe, the high-pressure water flow rapidly impacts the mineral powder attached to the lower bottom surface of the conveyor belt, preliminarily disintegrates the stubborn stains, and at the same time, the cleaning roller that fits tightly to the conveyor belt starts the cleaning operation synchronously. The several groups of bristles on the rubber cleaning roller rely on their own flexible material and fine texture. As the conveyor belt runs, the several groups of bristles on the rubber cleaning roller further peel off and remove the mineral powder particles remaining after being flushed by the water flow. The two-pronged approach allows the mineral powder on the outside of the conveyor belt to be thoroughly cleaned. In addition, through clever design, the power of the rubber cleaning roller comes from the servo motor, and the lower surface of the conveyor belt can be cleaned without adding additional power.

[0019] 3. The present invention provides a high-efficiency cleaning device for a coal mine belt conveyor. Under the action of the crawler belt, the conveyor belt squeezes the water absorption jacket on the cleaning roller, and the water absorption jacket absorbs the water stains remaining on the conveyor belt. The conveyor belt drives the water absorption jacket, the cleaning rod and the cleaning roller to rotate through friction. The rotation of the water absorption jacket also drives the squeezing roller to rotate through friction. The squeezing roller can squeeze out the water absorbed by the water absorption jacket during the rotation process, which is beneficial to cleaning the water stains remaining on the conveyor belt and is convenient for subsequent carrying and transportation of mineral powder materials.

[0020] 4. The present invention provides a high-efficiency cleaning device for a coal mine belt conveyor. When the annular sleeve rotates, it will drive the corrugated ring to move together. The corrugated groove on the corrugated ring drives the fixed clamping rod, the guide rod and the annular sleeve rod to move back and forth under the guidance of the support plate. The reciprocating movement of the annular sleeve rod will pull the octagonal round rod and the rubber cleaning roller to move axially back and forth. The reciprocating movement of the rubber cleaning roller enables the rubber cleaning roller to clean the mineral powder on the lower side of the conveyor belt more cleanly and thoroughly.

[0021] 5. The present invention provides an efficient cleaning device for a coal mine belt conveyor. This efficient cleaning device can superimpose multiple cleaning methods such as scraping, flushing, wiping, and cyclic reciprocating cleaning on the lower surface of the conveyor belt. On the one hand, it effectively ensures the cleaning effect of the efficient cleaning device on the mineral powder on the outer surface of the conveyor belt. On the other hand, through ingenious design, multiple cleaning methods are integrated together, with a small volume, convenient installation, and the power completely comes from the servo motor, without the need to additionally increase power, and it has strong practicability.

[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The coal mine belt conveyor includes two bases 1. A conveyor shaft 32 is rotatably installed on each base 1. A conveyor roller 33 is fixedly arranged on the outer surface of the conveyor shaft 32. A conveyor belt 34 is wound between the two conveyor rollers 33 in a matching manner. A bracket 2 is welded on one of the bases 1, and a servo motor 31 is installed on the bracket 2. The output end of the servo motor 31 is fixedly connected to the corresponding conveyor shaft 32.

[0043] The upper surface of the conveyor belt 34 is usually called the loading surface or working surface, which is mainly used for loading and transporting materials, and is uniformly referred to as the upper layer in this article. The lower surface of the conveyor belt 34 is generally called the non-loading surface or bottom surface. It contacts the driving roller, idler, etc., and relies on friction to realize the operation of the conveyor belt, and is uniformly referred to as the lower layer in this article.

[0044] Example 1: As Figures 1-10 shown, the present invention provides an efficient cleaning device for a coal mine belt conveyor, including a fitting scraping component arranged on the conveyor base 1. The fitting scraping component is arranged at the bottom of the conveyor belt 34 and is welded to the bracket 2 and the corresponding base 1 of the conveyor. The fitting scraping component can tighten the lower layer of the conveyor belt 34 and scrape off the mineral powder attached to the lower surface of the conveyor belt 34.

[0045] The fitting and scraping component includes a support plate 41. Support plates 41 and electric push rods 42 are welded to both sides of the base 1 provided with the bracket 2. The telescopic rods of the support plate 41 and the electric push rod 42 on the same side are both slidably connected. A lifting frame 43 is welded between the telescopic rods of the two electric push rods 42. Three transmission gears 44 are rotatably connected to the lifting frame 43. A crawler 45 is engaged between the three transmission gears 44. The three transmission gears 44 are located inside the crawler 45. A cleaning rod 48 is also rotatably installed between the two support plates 41. A cleaning roller 49 is welded between the two cleaning rods 48. A scraping plate 412 is welded between the two support plates 41.

[0046] During use, when the conveyor belt 34 of the coal mine conveyor starts to carry out coal transportation operations, the worker starts the servo motor 31 and the two electric push rods 42. The output shaft of the servo motor 31 rotates and drives the corresponding conveyor shafts 32 and conveyor rollers 33 to rotate. Through the cooperation of the conveyor belt 34, the other conveyor shaft 32 and conveyor roller 33 rotate synchronously. The conveyor belt 34 conveys the coal mine. After the coal mine is conveyed to the end and drops, the side of the conveyor belt 34 attached with mineral powder will be in a downward state. After the two electric push rods 42 are started, their telescopic rods retract and drive the lifting frame 43 to move downward. The lifting frame 43 drives the three transmission gears 44 and the crawler 45 to move downward. The crawler 45 moves downward and first contacts and pushes the upper surface of the lower layer of the conveyor belt 34, so that the conveyor belt 34 will be in a taut state. The bottom surface of the lower layer of the conveyor belt 34 will be in close contact with the cleaning roller 49. At the same time, the gap between the bottom surface of the lower layer of the conveyor belt 34 and the scraping plate 412 becomes smaller. The scraping plate 412 approaches and contacts the bottom surface of the lower layer of the conveyor belt 34. By applying a stable extrusion to the conveyor belt 34 by the crawler 45, the conveyor belt 34 is kept taut at all times, effectively avoiding the situation of unevenness. At the same time, the scraping plate 412 is used to scrape off the mineral powder attached to the lower surface of the conveyor belt 34. At the same time, under the extrusion of the crawler 45, the conveyor belt 34 is in close contact with the cleaning roller 49. As the conveyor belt 34 rotates, the cleaning roller 49 is driven to rotate, thus completing the cleaning work of the conveyor belt 34; when the coal mine is no longer conveyed, the staff turns off the servo motor 31 and controls the two electric push rods 42 to move upward and reset. The output shaft of the servo motor 31 no longer drives the conveyor shafts 32, conveyor rollers 33 and conveyor belt 34 to convey. The two electric push rods 42 reset and drive the lifting frame 43, the three transmission gears 44 and the crawler 45 to reset. The crawler 45 no longer squeezes and the conveyor belt 34 is no longer in close contact with the cleaning roller 49.

[0047] Embodiment 2: As Figures 4-7 and Figures 9-10As shown, on the basis of Example 1, a cleaning and combing component is also included, which is used to clean and wipe the conveyor belt 34. The cleaning and combing component includes a rotating rod 51, which is rotatably installed on the outer side of the lifting frame 43, and a flat key is connected to the rotating rod 51 with an internal gear 52. A fixed gear ring 53 is fixedly welded at one end of the conveying shaft 32 away from the servo motor 31, and the internal gear 52 is located inside the fixed gear ring 53. An annular sleeve 54 is rotatably installed on the two support plates 41, and an octagonal round rod 55 is slidably inserted between the two annular sleeves 54, that is, the octagonal round rod 55 can rotate with the annular sleeve 54, and at the same time, the octagonal round rod 55 can also slide in the annular sleeve 54 when driven by axial force, and the rotating rod 51 and the annular sleeve on the same side are connected. Pulley 1 551 and pulley 2 552 are also installed on the tube 54, and a belt 56 is wound between pulley 1 551 and pulley 2 552. A rubber cleaning roller 57 is welded between the two octagonal round rods 55. The outer surface of the rubber cleaning roller 57 is provided with a plurality of groups of rubber bristles. The plurality of groups of rubber bristles on the rubber cleaning roller 57 are used to clean the surface of the conveyor belt 34. Two arc plates 58 are also welded between the two support plates 41. The two arc plates 58 are respectively located on both sides of the rubber cleaning roller 57. Both ends of the arc plate 58 close to the scraper plate 412 are fixedly connected with a water inlet pipe 59. A water spray pipe 510 is fixedly connected between the two water inlet pipes 59. The water spray pipe 510 is provided with a plurality of nozzles. The plurality of groups of rubber bristles on the rubber cleaning roller 57 are arranged in a curved shape.

[0048] During operation, when the conveyor belt 34 of the coal mine conveyor starts coal transportation, the staff connect the external hoses to the two water inlet pipes 59 respectively. The external hoses connect the water pump to the two water inlet pipes 59, and then the water flows from the two water inlet pipes 59 to the water spray pipe 510. The water spray pipe 510 sprays water onto the lower bottom surface of the conveyor belt 34 through several nozzles on it. The water flushes the mineral powder adhering to the bottom surface of the conveyor belt 34. When the lifting frame 43 moves downward, it will synchronously drive the rotating rod 51, the internal gear 52 and the first pulley 551 to move downward together. The internal gear 52 will mesh with the fixed gear ring 53. The conveyor shaft 32 rotates to drive the fixed gear ring 53 to rotate. The fixed gear ring 53 drives the internal gear 52 to rotate. The internal gear 52 drives the first pulley 551 to rotate synchronously through the rotating rod 51. The first pulley 551 drives the second pulley 552 to rotate through the belt 56. The second pulley 552 drives the corresponding annular sleeve 54 to rotate. The annular sleeve 54 drives the octagonal round rod 55, the rubber cleaning roller 57 and another annular sleeve 54 to rotate synchronously. During the rotation of the rubber cleaning roller 57, it will brush and comb the mineral powder washed by water on the bottom surface of the conveyor belt 34, thus improving the cleaning effect of the conveyor belt. The two arc-shaped plates 58 will block the water splashed by the rubber cleaning roller 57 to prevent it from splashing everywhere. Through the continuous operation of the external water pump, water is pumped and introduced into the water spray pipe 510. With the spraying action of the water spray pipe 510, the high-pressure water flow rapidly impacts the mineral powder adhering to the outside of the conveyor belt 34, initially disintegrating stubborn stains. At the same time, the rubber cleaning roller 57 closely attached to the conveyor belt 34 starts the cleaning operation synchronously. The several groups of bristles on the rubber cleaning roller 57, relying on their flexible material and fine texture, as the conveyor belt 34 rotates, the several groups of bristles on the rubber cleaning roller 57 further strip and remove the mineral powder particles remaining after the water flow flushing. By combining these two methods, the mineral powder on the lower bottom surface of the conveyor belt 34 can be thoroughly washed. When the coal transportation stops, the servo motor 31 is turned off, and the conveyor belt 34 no longer rotates. The two electric push rods 42 reset to drive the lifting frame 43 to reset. The lifting frame 43 drives the rotating rod 51 and the internal gear 52 to reset together. The internal gear 52 disengages from the fixed gear ring 53, and the rubber cleaning roller 57 also stops rotating.

[0049] Embodiment 3: As Figure 8 and Figure 9 shown, on the basis of Embodiment 2, it further includes a water absorption component. The water absorption component is arranged between the two support plates 41. The water absorption component absorbs the residual water stains on the conveyor belt 34. The water absorption component includes a water absorption sleeve 61. The water absorption sleeve can be made of rubber, sponge or other materials with water absorption performance. The water absorption sleeve 61 is sleeved on the surface of the cleaning roller 49. A fixed round rod 62 is welded between the two support plates 41. A squeezing roller 63 is rotatably installed in the middle of the fixed round rod 62. The squeezing roller 63 and the cleaning roller 49 form squeezing on the water absorption sleeve 61.

[0050] Working principle: Under the action of the crawler 45, the conveyor belt 34 presses against the water-absorbing sleeve 61 on the cleaning roller 49. The water-absorbing sleeve 61 absorbs the water stains remaining on the bottom surface of the conveyor belt 34. The conveyor belt 34 drives the water-absorbing sleeve 61, the cleaning rod 48, and the cleaning roller 49 to rotate through friction. The rotation of the water-absorbing sleeve 61 also drives the extrusion roller 63 to rotate through friction. The extrusion roller 63 rotates below and squeezes out the water absorbed by the water-absorbing sleeve 61.

[0051] Embodiment 4: As Figures 5-6 shown, on the basis of Embodiment 3, it further includes a reciprocating component. The reciprocating component is arranged on the support plate 41 that is far from the servo motor 31. The reciprocating component is used to drive the rubber cleaning roller 57 to axially reciprocate. The reciprocating component includes a corrugated ring 71 fixedly welded to the outer side of the annular sleeve 54. The outer surface of the corrugated ring 71 is provided with a corrugated card slot 74. An annular sleeve rod 72 is rotatably sleeved on the outer surface of one end of the octagonal round rod 55 close to the corrugated ring 71. That is, the octagonal round rod 55 and the annular sleeve rod 72 can rotate relative to each other, but the annular sleeve rod 72 cannot slide axially along the octagonal round rod 55. The octagonal round rod 55 and the annular sleeve rod 72 can be installed together through bearings. Guide rods 75 are respectively welded to the opposite sides of the annular sleeve rod 72. The other ends of the two guide rods 75 respectively slide through the corresponding support plate 41. After passing through the support plate 41, a fixed clamping rod 73 is welded. The end of the fixed clamping rod 73 far from the guide rod 75 slides into the corrugated card slot 74. The guide rod 75 can freely slide back and forth on the support plate 41 after being stressed. Guide holes can also be provided on the support plate 41, and the guide rod 75 passes through the guide holes to facilitate reciprocating movement. In addition, the structures and distances of the two clamping points where the corrugated card slot 74 contacts the fixed clamping rod 73 are the same, so that the corrugated card slot 74 can apply force to the two fixed clamping rods 73 synchronously, and it is more stable during reciprocating motion.

[0052] Working principle: The rotation of the annular sleeve 54 drives the octagonal round rod 55, the cleaning roller 57, and the corrugated ring 71 to rotate synchronously. When the corrugated ring 71 rotates, it drives the fixed clamping rod 73, the guide rod 75, and the annular sleeve rod 72 to reciprocate under the guiding action of the support plate 41 through the corrugated card slot 74 on it. The reciprocating movement of the annular sleeve rod 72 drives the octagonal round rod 55 and the rubber cleaning roller 57 to axially reciprocate together. The reciprocating movement of the rubber cleaning roller 57 makes the rubber cleaning roller 57 clean the ore powder at the bottom of the lower layer of the conveyor belt 34 more cleanly and thoroughly, further improving the cleaning effect.

[0053] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
