Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine conveyor technology, specifically a coal mine conveyor with a dust collection structure. Background Technology
[0002] Coal mine conveyors are specialized equipment used for transporting coal, gangue, materials, and personnel underground or on the surface of coal mines. They are an indispensable logistics and transportation tool in coal mine production, efficiently and continuously transporting coal from the mining site to the surface or designated locations. This is of great significance for improving coal mine production efficiency, reducing labor intensity, and ensuring production safety. However, traditional coal mine conveyors generate a large amount of dust during operation, which not only pollutes the environment but also endangers the health of workers.
[0003] Existing coal mine conveyors typically generate a large amount of dust at the feeding end during operation. The dust is then collected by a dust collection structure, which requires the use of atomized water mist to suppress the dust. However, in this process, the dust mixes with the water and adheres to the inner wall of the collection structure. If not cleaned in time, this not only forms stubborn grime that is difficult to remove, increasing maintenance difficulty, but also affects the dust collection efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a coal mine conveyor with a dust collection structure to solve the problem mentioned in the background art that the dust collection structure of the coal mine conveyor uses atomized water mist to suppress dust. However, in this way, the dust and water mix and adhere to the inner wall of the collection structure. If not cleaned in time, it will not only form difficult-to-remove mud and increase the difficulty of maintenance, but also affect the dust collection effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal mine conveyor with a dust collection structure, comprising a frame, a first motor mounted on the frame, a conveyor belt rotatably mounted on the frame, a collection box mounted on the top of the frame, a collection mechanism disposed inside the collection box, a water pump mounted on the top of the collection box, a water pipe mounted at the output end of the water pump, a spray pipe connected to one end of the water pipe, a scraper mechanism disposed on the collection mechanism, and an adjustment mechanism disposed on the scraper mechanism.
[0006] Preferably, the collection mechanism includes a second motor and a first bevel gear mounted on the output shaft of the second motor. The second motor is mounted on the collection box. The surface of the first bevel gear meshes with the second bevel gear. A first rotating rod is connected to the center of one side of the second bevel gear, and a fan is connected to one end of the first rotating rod.
[0007] Preferably, the angle between the extended axis of the first bevel tooth and the extended axis of the second bevel tooth is 90 degrees.
[0008] Preferably, the scraper mechanism includes a second rotating rod and a fixed rod mounted on the second rotating rod. The second rotating rod is connected to the axis on the other side of the second bevel tooth, and a scraper is provided at each end of the fixed rod.
[0009] Preferably, the two sets of scrapers are arranged in a spiral shape.
[0010] Preferably, the adjusting mechanism includes a dovetail groove and a spring installed in the dovetail groove. The dovetail groove is opened on one side of the end of the fixed rod. One end of the spring is connected to a dovetail block. A threaded hole is opened through the inner wall of the dovetail groove. A fixing bolt is threaded into the threaded hole. The scraper is slidably connected to the fixed rod through the dovetail block and the dovetail groove.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. When the conveyor belt starts transporting coal, dust flies up. The water pump starts immediately, and the water pipes and spray nozzles atomize water and spray it into the collection box. Then, the second motor starts, driving the first and second bevel gears to rotate, thereby driving the fan to generate suction force, which sucks the flying dust into the collection box. After the dust is sprayed and suppressed, the dust and water mix into mud during this process. The scraper mechanism starts working simultaneously to scrape the mixture out of the collection box in time, avoiding the accumulation of dust on the inner wall of the collection box, which would affect subsequent use and dust collection, and improving the efficiency of the equipment.
[0013] 2. During operation, coal dust gradually accumulates and thickens on the inner wall of the collection box. At this time, the scraper can be moved inward along the fixed rod by sliding the dovetail block and dovetail groove to adjust the distance between the scraper and the inner wall of the collection box. Then, the dovetail block is fixed by the fixing bolt through the threaded hole to fix the scraper position, ensuring that the scraper can continuously and effectively remove dust. This avoids damage to the scraper due to excessive resistance caused by dust accumulation. The precise adjustment of the adjustment mechanism ensures the fit between the scraper and the inner wall of the collection box, thereby making the scraping effect more thorough.

[0019] 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.
[0020] Example 1: Please refer to Figures 1-3 A coal mine conveyor with a dust collection structure includes a frame 1, a first motor 2 mounted on the frame 1, and a conveyor belt 3 rotatably mounted on the frame 1. The conveyor belt 3 is driven to rotate by the first motor 2. A collection box 4 is mounted on the top of the frame 1. Through the collection box 4, when flying dust is collected, it is then concentrated and discharged onto the conveyor belt 3 through its rear end. This not only prevents coal mine dust from affecting the environment and workers, but also allows the coal mine dust to be directly carried away by the conveyor belt 3. The collection box 4 has a collection mechanism 5 inside. Through the installation direction of the collection mechanism 5, the flying dust at the feeding end of the conveyor belt 3 can be directly collected during use, preventing coal mine dust from affecting the environment and workers. The top of the collection box 4... A water pump 6 is installed, and a water pipe 7 is installed at the output end of the water pump 6. One end of the water pipe 7 is connected to a spray pipe 8. The water pump 6 pressurizes the water and atomizes it from the water pipe 7 and the spray pipe 8, which can effectively suppress the dust flying inside the collection box 4. At the same time, the mixture of water and dust can be easily discharged from the collection box 4. A scraper mechanism 9 is set on the collection mechanism 5. With the scraper mechanism 9, the mixed water and dust can be directly scraped off and discharged from the inner wall of the collection box 4 during use, avoiding dust adhesion and accumulation inside the collection box 4. An adjustment mechanism 10 is set on the scraper mechanism 9. Through the adjustment mechanism 10, the distance between the scraper mechanism 9 and the inner wall of the collection box 4 can be adjusted according to the amount of dust to ensure the best scraping effect, improve dust treatment efficiency, and ensure long-term stable operation of the equipment.
[0021] The collection mechanism 5 includes a second motor 51 and a first bevel gear 52 mounted on the output shaft of the second motor 51. The second motor 51 is mounted on the collection box 4. The surface of the first bevel gear 52 is engaged with a second bevel gear 53. By setting the first bevel gear 52 and the second bevel gear 53, the transmission direction can be shifted so that the second motor 51 can be mounted outside the collection box 4, avoiding the impact of collected dust and sprayed water mist on the normal operation of the second motor 51. A first rotating rod 54 is connected to one side of the shaft of the second bevel gear 53. A fan 55 is connected to one end of the first rotating rod 54. The angle between the extended axis of the first bevel gear 52 and the extended axis of the second bevel gear 53 is 90 degrees.
[0022] The scraper mechanism 9 includes a second rotating rod 91 and a fixed rod 92 mounted on the second rotating rod 91. The second rotating rod 91 is connected to the axis on the other side of the second bevel tooth 53. The second bevel tooth 53 can drive the first rotating rod 54 and the second rotating rod 91, which improves the power utilization efficiency. A scraper 93 is provided at each end of the fixed rod 92. The two sets of scrapers 93 are arranged in a spiral shape. The spiral arrangement ensures that the inner wall of the collection box 4 can be covered, which improves the scraping efficiency and reduces dust residue. At the same time, the spiral arrangement also facilitates the smooth discharge of the mixture and avoids accumulation.
[0023] Specifically, when the feeding end of conveyor belt 3 begins transporting coal, dust flies up. Water pump 6 then starts, and water pipe 7 and spray pipe 8 atomize water and spray it into collection box 4. Then, the second motor 51 is started, driving the first bevel gear 52 and the second bevel gear 53 to rotate, thereby driving fan 55 to generate suction force, sucking the flying dust into collection box 4. After the dust is suppressed by water spraying, the dust and water mix into slurry during this process. The scraper 93 of scraper mechanism 9 starts working simultaneously, scraping the mixture from collection box 4 in a timely manner, avoiding the accumulation of dust on the inner wall of collection box 4, which would affect subsequent use and dust collection, and improving the efficiency of equipment use.
[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The adjusting mechanism 10 includes a dovetail groove 101 and a spring 102 installed in the dovetail groove 101. The dovetail groove 101 is opened on one side of the end of the fixed rod 92. One end of the spring 102 is connected to a dovetail block 103. A threaded hole 104 is opened through the inner wall of the dovetail groove 101. A fixing bolt 105 is threaded into the threaded hole 104. The scraper 93 is slidably connected to the fixed rod 92 through the dovetail block 103 and the dovetail groove 101.
[0025] Specifically, during the operation of the scraper 93, the coal dust on the inner wall of the collection box 4 gradually accumulates and thickens. At this time, the scraper 93 can be moved inward along the fixed rod 92 by sliding the dovetail block 103 and the dovetail groove 101 to adjust the distance between the scraper 93 and the inner wall of the collection box 4. Then, the dovetail block 103 is fixed by the fixing bolt 105 through the threaded hole 104 to fix the position of the scraper 93, so as to ensure that the scraper 93 can continuously and effectively scrape off the dust and avoid damage caused by excessive resistance during the operation of the scraper 93 due to dust accumulation. Through the precise adjustment of the adjustment mechanism 10, the fit between the scraper 93 and the inner wall of the collection box 4 is guaranteed, thereby making the scraping effect more thorough.
[0026] Furthermore, the design of the adjustment mechanism 10 makes maintenance simpler and more efficient. When the scraper 93 needs to be replaced or repaired, the operator only needs to loosen the fixing bolts 105 to easily remove the dovetail block 103 from the dovetail groove 101, thus facilitating and quickly replacing or maintaining the scraper 93, greatly reducing equipment downtime and improving overall work efficiency.
