[0002] Belt conveyors have the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can be conveniently programmed and automated. They are widely used in the field of ore conveying. When the ore conveyor unloads ore onto the stockyard, due to the large falling height of the ore and the long exposure time of the ore in the air during the unloading process, the powder components in the ore are easily blown away by the wind, causing serious dust pollution. Therefore, a spray dust prevention system needs to be installed on the belt conveyor to suppress dust.
[0003] However, the traditional spray dust reduction system on the belt conveyor is fixedly installed above or on the side of the conveyor. Since the sizes of the ores transported on the conveyor belt are different, when the spray heads are installed too low, they will be damaged when hitting larger ores. But when the spray heads are installed too high, it will accelerate the evaporation of the water sprayed by the spray heads, and then the dust prevention effect is not ideal. Therefore, it is not flexible and convenient enough, affecting the dust prevention effect. Content of the Utility Model

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1 - 5As shown in the figure, a transportation device with dust-proof function for open-pit mining includes a mounting frame 1. At the top of the mounting frame 1, two moving structures 2 are installed. The moving structure 2 includes a slide rail 201. The slide rail 201 is installed at the top of the mounting frame 1. A slider 204 is slidably connected in the slide rail 201. A height adjustment structure 3 is installed on the slider 204. The height adjustment structure 3 includes a sliding frame 301. The sliding frame 301 is installed at the top of the slider 204. A fixed rod 302 is slidably connected to the sliding frame 301. A groove 306 is opened at the bottom end of the fixed rod 302. A second tension spring 304 is installed in the groove 306. The top end of the second tension spring 304 is fixedly connected to the inner wall of the fixed rod 302, and the bottom end of the second tension spring 304 is fixedly connected to the bottom end of the sliding frame 301. One side of the slider 204 is fixedly connected to a first tension spring 203. The other end of the first tension spring 203 is fixedly connected to the inner wall of the slide rail 201. A spraying structure 4 is installed at the top end of the fixed rod 302. A conveyor belt 5 is installed inside the mounting frame 1; when the ore on the conveyor belt 5 is too large, the top end of the ore abuts against the nozzle 402 upward. The nozzle 402 drives the steel pipe 401 to move upward. At the same time, the steel pipe 401 drives the fixed rod 302 to slide upward through the connecting rod 10 and the hoop 9. The fixed rod 302 drives the second tension spring 304 to stretch, so that the spraying structure 4 does not abut against the ore and move forward, effectively avoiding frictional damage to the nozzle 402 by the ore. When the nozzle 402 and the steel pipe 401 rise, the conveyor belt 5 drives the ore to continue to move forward. Under the abutment of the ore, the nozzle 402 drives the steel pipe 401 to move forward. When the steel pipe 401 moves forward, it drives the fixed rod 302 and the sliding frame 301 to move forward. The sliding frame 301 drives the slider 204 to slide forward in the slide rail 201. At the same time, the slider 204 drives the first tension spring 203 to stretch. When the ore passes through the dust removal system, the ore no longer abuts against the steel pipe 401 and the nozzle 402. After losing the abutting force, the first tension spring 203 resets and drives the slider 204 to slide backward. At the same time, the second tension spring 304 resets and drives the fixed rod 302 to slide downward, thereby driving the steel pipe 401 to return to its original height and horizontal position, enabling the steel pipe 401 and the nozzle 402 to elastically move along the conveying direction of the ore, avoiding damage to the nozzle 402 during the forward movement of the ore, so that the dust-proof system can operate stably, thereby increasing the flexibility of the dust removal system and making the dust-proof effect better.
[0023] As a technical optimization scheme of the present invention, the two moving structures 2 are symmetrically distributed left and right about the middle of the conveyor belt 5, and the slide rail 201 is perpendicular to the sliding frame 301; this makes the steel pipe 401 and the nozzle 402 above the conveyor belt 5, facilitating the spraying and dust suppression of the ore.
[0024] As a technical optimization solution of the present utility model, a guide rod 202 is fixedly connected inside the slide rail 201, and the slider 204 is slidably connected to the guide rod 202; while the slider 204 slides in the slide rail 201, the slider 204 also slides on the guide rod 202. The guide rod 202 has a guiding effect on the slider 204, and at the same time prevents the slider 204 from slipping off from above, increasing the sliding stability of the slider 204.
[0025] As a technical optimization solution of the present utility model, a anti-slip block 305 is fixedly connected to the bottom end of the fixed rod 302, and a mounting seat 303 is fixedly connected to the bottom end of the sliding frame 301. The mounting seat 303 is installed on the top end of the slider 204; the setting of the anti-slip block 305 prevents the fixed rod 302 from slipping out of the sliding frame 301, making the sliding of the fixed rod 302 more stable.
[0026] As a technical optimization solution of the present utility model, a hoop 9 is installed at the top end of the fixed rod 302. One side of the hoop 9 facing the conveyor belt 5 is fixedly connected with a connecting rod 10. The top end of the connecting rod 10 is fixedly connected with a spraying structure 4. The spraying structure 4 includes a steel pipe 401. The top end of the connecting rod 10 is fixedly connected with a steel pipe 401. The installation direction of the steel pipe 401 is perpendicular to the moving direction of the conveyor belt 5. A plurality of nozzles 402 are equidistantly installed at the bottom end of the steel pipe 401. One end of the steel pipe 401 is connected with a hose 403. Both ends of the steel pipe 401 are threadedly connected with plugs 404. The cross section of the plug 404 is in a "T" shape structure; when the control switch of the dust prevention system is turned on, when water source enters the steel pipe 401 from the hose 403, it is atomized and sprayed out from the nozzles 402, so as to perform dust reduction treatment on the ore at the bottom end of the nozzles 402, which can effectively alleviate the environmental pollution caused by the powder in the ore. At the same time, the setting of the plugs 404 at both ends of the steel pipe 401 makes the steel pipe 401 more sealed and is convenient for disassembly and cleaning.
[0027] As a technical optimization solution of the present utility model, one end of the mounting frame 1 is rotatably connected with a driving roller 7, and the other end of the mounting frame 1 is rotatably connected with a driven roller 8. A plurality of triple idler rollers 6 are equidistantly installed on the mounting frame 1. The triple idler rollers 6 are located between the driving roller 7 and the driven roller 8. The conveyor belt 5 is wound around the outside of the triple idler rollers 6, the driving roller 7 and the driven roller 8; First, start the motor. The motor drives the driving roller 7 to rotate. The driving roller 7 drives the conveyor belt 5 to move. At the same time, the conveyor belt 5 drives the driven roller 8 to rotate during the movement process, so that the conveyor belt 5 runs stably, which is convenient for transporting the ore. When the conveyor belt 5 is in the running state, under the action of friction, the conveyor belt 5 drives the triple idler rollers 6 to rotate. The triple idler rollers 6 have a supporting effect on the conveyor belt 5 and can support the weight of the conveyor belt 5 and the ore on the conveyor belt 5 during the running process, reducing the wear of the conveyor belt 5 and improving the conveying efficiency.
[0028] When the utility model is in use, first start the motor. The motor drives the driving roller 7 to rotate, and the driving roller 7 drives the conveyor belt 5 to move. At the same time, during the movement of the conveyor belt 5, the driven roller 8 is driven to rotate, so that the conveyor belt 5 runs stably, facilitating the transportation of ore. When the conveyor belt 5 is in the running state, under the action of friction, the conveyor belt 5 drives the triple idler 6 to rotate. The triple idler 6 has a supporting effect on the conveyor belt 5 and can support the weight of the conveyor belt 5 and the ore on the conveyor belt 5 during the running process, reducing the wear of the conveyor belt 5 and improving the conveying efficiency. Then, turn on the control switch of the dust prevention system. When the water source enters the steel pipe 401 from the hose 403, it is atomized and sprayed out from the nozzle 402, thereby performing dust reduction treatment on the ore at the bottom of the nozzle 402, which can effectively alleviate the environmental pollution caused by the powder in the ore. At the same time, the plug 404 at both ends of the steel pipe 401 makes the steel pipe 401 more airtight and is convenient for disassembly and cleaning. When the ore on the conveyor belt 5 is too large, the top of the ore abuts against the nozzle 402 upwards. The nozzle 402 drives the steel pipe 401 to move upwards. At the same time, the steel pipe 401 drives the fixed rod 302 to slide upwards through the connecting rod 10 and the hoop 9. The fixed rod 302 drives the second tension spring 304 to elongate, so that the spraying structure 4 does not abut against the ore and move forward, effectively avoiding the frictional damage of the ore to the nozzle 402. When the nozzle 402 and the steel pipe 401 rise, the conveyor belt 5 drives the ore to continue to move forward. Under the abutment of the ore, the nozzle 402 drives the steel pipe 401 to move forward. When the steel pipe 401 moves forward, it drives the fixed rod 302 and the sliding frame 301 to move forward. The sliding frame 301 drives the slider 204 to slide forward in the slide rail 201. At the same time, the slider 204 drives the first tension spring 203 to elongate. When the ore passes through the dust removal system, the ore no longer abuts against the steel pipe 401 and the nozzle 402. After losing the abutting force, the first tension spring 203 resets and drives the slider 204 to slide backward. At the same time, the second tension spring 304 resets and drives the fixed rod 302 to slide downward, thereby driving the steel pipe 401 to return to its original height and horizontal position, enabling the steel pipe 401 and the nozzle 402 to elastically move along the conveying direction of the ore, avoiding damage to the nozzle 402 during the forward movement of the ore, so that the dust prevention system can operate stably, further increasing the flexibility of the dust removal system and making the dust prevention effect better.
