Description

Technical Field

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

[0002] Coal mine electromechanical equipment is the basic equipment for coal mine operation. During the coal mining and production process, a large number of coal mine mechanical equipment, electrical equipment and electromechanical equipment are required to operate, which mainly include lifting equipment, ventilation equipment, compressed air equipment, drainage equipment, mining equipment, transportation equipment, etc. The transportation and transmission equipment of coal mines is crucial, which is related to the stability and safety of coal mine transportation.

[0003] In the mining, coal processing, and related industries, transportation equipment, particularly conveyor belt systems, plays a vital role. They operate continuously, moving large quantities of coal from the mining site or processing area to its destination. However, over time and with frequent use, these conveyor belts inevitably accumulate a thick layer of coal debris, fine coal particles, and airborne dust on their surfaces, forming a difficult-to-ignore deposit.

[0004] Currently, most companies still rely on traditional manual cleaning methods to address this issue. Workers must use handheld tools such as brooms and shovels to clean the conveyor belts between runs or during downtime. This method is not only labor-intensive and poses potential health risks to workers (such as respiratory illnesses caused by long-term inhalation of coal dust), but also often produces unsatisfactory cleaning results and low efficiency, increasing operating costs and time costs for companies. Furthermore, manual cleaning carries safety risks, especially when cleaning while the conveyor belt is running rapidly or not fully stopped, where accidents can occur with the slightest carelessness.

[0005] Therefore, developing a more efficient and safe belt cleaning device has become an urgent problem to be solved in the coal transportation industry. Utility Model Content

[0006] The purpose of this utility model is to propose and design a self-cleaning coal mine electromechanical transportation device to address the problems of low efficiency, poor cleaning effect and safety risks caused by the traditional manual cleaning method of existing coal mine electromechanical transportation belts, so as to realize automatic and timely cleaning of the belts during transportation, ensure the cleaning effect and improve the cleaning efficiency.

[0007] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a self-cleaning electromechanical transportation device for coal mines, including a conveyor body, a conveyor belt installed on the conveyor body, a driving mechanism and an opening and closing replacement mechanism provided on the conveyor body, a roller brush provided between the driving mechanism and the opening and closing replacement mechanism, the roller brush close to the conveyor belt surface in the conveyor body, the roller brush is located below the conveyor belt, because the conveyor belt is installed on the transmission roller and is driven by the transmission roller for circulation, relative to the transmission roller, the conveyor belt located above the transmission roller is the upper conveyor belt, and the conveyor belt located below the transmission roller is the lower conveyor belt, and the roller brush located below the conveyor belt means being located below the lower conveyor belt to clean the surface of the lower conveyor belt that does not transport goods, a scraper is provided on one side of the roller brush, and a collection box is provided below the roller brush and the scraper. The scraper and roller brush can clean the surface of the conveyor belt at the same time. The scraper first scrapes off the larger coal slag attached to the surface of the conveyor belt, and then drives the roller brush to rotate through the driving mechanism to clean the conveyor belt. The roller brush can be replaced by setting an opening and closing replacement mechanism to clean the fine coal slag and dust on the surface of the conveyor belt. The double cleaning makes the device more effective in cleaning the conveyor belt. The collection box is set to facilitate the collection of the coal slag and dust cleaned by the roller brush and scraper for subsequent processing.

[0008] Furthermore, one end of the roller brush is provided with a first cross rod adapted to the driving mechanism, and the other end of the roller brush is provided with a second cross rod adapted to the opening and closing replacement mechanism, thereby achieving installation and matching of the scraper.

[0009] Furthermore, there are two scrapers, one on each side of the roller brush. A fixed plate is spaced apart on both sides of the roller brush. The fixed plate is detachably connected to the conveyor body via bolts. The scrapers are mounted on the fixed plate and spaced apart from the scrapers. This allows for the installation of the scrapers. Furthermore, the scrapers are provided on both sides of the roller brush, allowing the conveyor belt to be scraped off larger coal slag attached to the surface of the conveyor belt in both forward and reverse directions.

[0010] Furthermore, the driving mechanism includes a fixed block fixedly connected to the conveyor body, a first rotating block rotatably connected to the side of the fixed block close to the roller brush, a first cross slot adapted to fit the first cross rod being formed on the side of the first rotating block close to the roller brush, and a motor being provided on the side of the fixed block away from the roller brush, the output end of the motor being connected to the first rotating block via a rotating shaft, thereby achieving installation and fit of the roller brush and enabling it to be driven to rotate smoothly by the motor.

[0011] Furthermore, the opening and closing mechanism includes a first L-shaped plate and a second L-shaped plate arranged at intervals. The opening and closing plate is rotatably connected to the first L-shaped plate. A locking assembly is provided between the opening and closing plate and the second L-shaped plate. A second rotating block is rotatably connected to the side of the opening and closing plate near the roller brush. The second rotating block has a second cross slot on the side near the roller brush that is compatible with the second cross rod. The cross rod and the cross slot cooperate to allow the roller brush to rotate with the rotating block.

[0012] Furthermore, an adjustment block is fixed to each of the first and second L-shaped plates, and an adjustment slot is provided on the conveyor body. A bolt is mounted on the adjustment block, and the adjustment block is fastened to the adjustment slot via the bolt. The adjustment block and the adjustment slot cooperate to achieve the movement and adjustment of the first and second L-shaped plates, thereby achieving the separation or proximity of the opening and closing plate relative to the roller brush. When the roller brush needs to be removed, the bolt is turned to move the opening and closing plate away from the roller brush, allowing the roller brush to disengage from the closing plate. The opening and closing plate is then rotated to create a gap between the first and second L-shaped plates, allowing the roller brush to be removed.

[0013] Furthermore, the locking assembly includes a cavity formed vertically at one end of the opening and closing plate, with two upper and lower limit rods movably inserted into the cavity, a spring disposed between the two limit rods, and limit grooves adapted to fit the limit rods on opposite sides of the conveyor body and the second L-shaped plate. The opening and closing plate is provided with a strip-shaped notch conductively connected to the cavity, with two paddles disposed within the strip-shaped notch, each of which is fixedly connected to the two limit rods. By pressing the two paddles relative to each other, the two limit rods are driven to move relative to each other, causing the two limit rods to simultaneously disengage from the limit grooves, thereby opening the opening and closing plate.

[0014] Furthermore, two connecting plates are fixedly connected to the bottom of the conveyor body. T-shaped slots are horizontally defined on one side of the bottom of each connecting plate. T-shaped sliders that fit within the slots are fixedly connected to both sides of the top of the collection box. The collection box is detachably connected to the conveyor body through the cooperation of the T-shaped slots and sliders. The detachable design of the collection box facilitates the dumping of coal slag and dust within the collection box.

[0015] Furthermore, a handle is fixedly connected to one side of the collection box, and universal wheels are provided at the four corners of the bottom of the collection box. The handle and the universal wheels are provided to facilitate the movement of the collection box so as to move it to a designated location to dump the collected coal slag and dust.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages:

[0017] This solution provides a self-cleaning electromechanical conveyor for coal mines. A scraper first removes larger coal slag attached to the conveyor belt surface. Then, a drive mechanism drives a roller brush to clean the finer coal slag and dust from the conveyor belt surface. This dual cleaning process improves the conveyor belt cleaning effect. An opening and closing mechanism facilitates the replacement of the roller brush, while a collection box facilitates the collection of coal slag and dust removed by the roller brush and scraper for subsequent processing. This achieves automated and timely cleaning of the belt during transportation, ensuring effective cleaning and improving cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1 to 5 As shown, this specific embodiment provides a self-cleaning electromechanical transportation device for coal mines, including a conveyor body 1, a conveyor belt installed on the conveyor body 1, a driving mechanism 2 and an opening and closing replacement mechanism 3 are provided on the conveyor body 1, and a roller brush 4 is provided between the driving mechanism 2 and the opening and closing replacement mechanism 3. The roller brush 4 is close to the surface of the conveyor belt in the conveyor body 1, and the roller brush 4 is located below the conveyor belt. Because the conveyor belt is installed on the transmission roller and is driven by the transmission roller for circulation, relative to the transmission roller, the conveyor belt located above the transmission roller is the upper conveyor belt, and the conveyor belt located below the transmission roller is the lower conveyor belt. The roller brush 4 located below the conveyor belt here means being located below the lower conveyor belt. , in order to clean the surface of the lower conveyor belt where no goods are transported, a scraper 8 is provided on one side of the roller brush 4, and a collection box 9 is provided below the roller brush 4 and the scraper 8. There are two scrapers 8, and the two scrapers 8 are respectively located on both sides of the roller brush 4. A fixed plate 7 is provided on both sides of the roller brush 4 at intervals. The fixed plate 7 is detachably connected to the conveyor body 1 by bolts. The scraper 8 is installed on the fixed plate 7 and is arranged at intervals with the scraper 8 to realize the installation of the scraper 8. The scraper 8 and the roller brush 4 can clean the conveyor belt surface at the same time. The scraper 8 first scrapes off the larger coal slag attached to the conveyor belt surface, and then drives the roller brush 4 to rotate through the driving mechanism 2 to clean the conveyor belt. The cleaned coal slag falls into the collection box 9. Among them, the scrapers 8 are provided on both sides of the roller brush 4, and the larger coal slag attached to the conveyor belt surface can be scraped off first when the conveyor belt is forward or reversed.

[0027] Among them, see Figure 3 and Figure 4One end of the roller brush 4 is provided with a first cross-insertion rod 5 that is compatible with the drive mechanism 2, and the other end of the roller brush 4 is provided with a second cross-insertion rod 6 that is compatible with the opening and closing replacement mechanism 3, thereby achieving the installation and matching of the scraper 8. The drive mechanism 2 includes a fixed block 201 fixedly connected to the conveyor body 1. The side of the fixed block 201 close to the roller brush 4 is rotatably connected to the first rotating block 202. The side of the first rotating block 202 close to the roller brush 4 is provided with a first cross-slot 203 that is compatible with the first cross-insertion rod 5. The side of the fixed block 201 away from the roller brush 4 is provided with a motor 204. The output end of the motor 204 is connected to the first rotating block 202 via a rotating shaft, thereby achieving the installation and matching of the roller brush 4 and enabling it to be driven to rotate smoothly by the motor 204.

[0028] Among them, see Figure 2 The opening and closing replacement mechanism 3 includes a first L-shaped plate 301 and a second L-shaped plate 302 arranged at intervals. The first L-shaped plate 301 is rotatably connected to an opening and closing plate 303. A locking assembly 304 is provided between the opening and closing plate 303 and the second L-shaped plate 302. The opening and closing plate 303 is rotatably connected to a second rotating block 305 on the side close to the roller brush 4. The second rotating block 305 is provided with a second cross slot 306 adapted to the second cross rod 6 on the side close to the roller brush 4. The roller brush 4 can rotate together with the rotating block through the cooperation of the cross rod and the cross slot. An adjustment block 307 is fixed on both the first L-shaped plate 301 and the second L-shaped plate 302. An adjustment slot is provided on the conveyor body 1. A bolt is installed on the adjustment block 307. The adjustment block 307 is fastened to the adjustment slot by the bolt. The cooperation between the adjustment block 307 and the adjustment slot enables the movement and adjustment of the first L-shaped plate 301 and the second L-shaped plate 302, thereby enabling the opening and closing plate 303 to move away from or close to the roller brush 4. When the roller brush 4 needs to be removed, the bolt is tightened to move the opening and closing plate 303 away from the roller brush 4, so that the roller brush 4 is separated from the closing plate 303. Then, the locking assembly 304 is operated to rotate the opening and closing plate 303 to open a gap between the first L-shaped plate 301 and the second L-shaped plate 302, and the roller brush 4 is taken out. For details, see Figure 5 The locking assembly 304 includes a cavity 3041 vertically defined at one end of the opening and closing plate 303. Two vertically spaced limiting rods 3042 are movably inserted into the cavity 3041. A spring 3043 is disposed between the two limiting rods 3042. Limiting slots 3044 corresponding to the limiting rods 3042 are defined on opposing sides of the conveyor body 1 and the second L-shaped plate 302. A strip-shaped notch 3045 is defined on the outer side of the opening and closing plate 303, electrically connected to the cavity 3041. Two paddles 3046 are disposed within the strip-shaped notch 3045, each fixedly connected to the two limiting rods 3042. Pressing the two paddles 3046 relative to each other causes the two limiting rods 3042 to simultaneously disengage from the limiting slots 3044, thereby opening the opening and closing plate 303.

[0029] Also, see Figure 1 and Figure 2 The bottom of the conveyor body 1 is fixedly connected to two connecting plates 10, and a T-shaped chute 11 is provided on one side of the bottom of the two connecting plates 10 in the horizontal direction. T-shaped sliders 12 that match the T-shaped chute 11 are fixedly connected to both sides of the top of the collection box 9. The collection box 9 is detachably connected to the conveyor body 1 through the cooperation of the T-shaped chute 11 and the T-shaped slider 12. The detachable setting of the collection box 9 facilitates the dumping of the coal slag and dust in the collection box 9. A handle 13 is fixedly connected to one side of the collection box 9, and universal wheels 14 are provided at the four corners of the bottom of the collection box 9. The provision of the handle 13 and the universal wheel 14 facilitates the movement of the collection box 9, so that it can be moved to a designated location to dump the collected coal slag and dust.

[0030] Its working principle is: when in use, start the motor 204 to drive the roller brush 4 to rotate, and clean the fine coal slag and dust attached to the surface of the conveyor belt. At the same time, the scraper 8 will scrape off the larger coal slag attached to the conveyor belt. The coal slag and dust cleaned by the roller brush 4 and the scraper 8 will fall into the collection box 9 for collection, which is convenient for subsequent processing.
