[0002] When transporting ore underground, mining conveyors are generally used. During the ore transport process, dust is raised. In order to ensure the overall air quality underground, water is usually sprayed on the ore on the conveyor to reduce dust generation.

[0003] To address the problem that existing dust suppression spraying devices cannot adapt to mining conveyors of varying widths, patent CN218890319U discloses a dust suppression spraying device for ore conveying, belonging to the field of mining equipment technology. It includes a first support and a second support, with a first sliding rod and a second sliding rod slidably mounted inside the first and second supports respectively. A water spray pipe is sleeved on the outer side of both the first and second sliding rods, and both the first and second sliding rods are slidably connected to the water spray pipe. A water injection pipe is fixedly connected to the top of the water spray pipe, and multiple evenly distributed nozzles are installed at the bottom of the water spray pipe. Although this solves the existing technical problem, the following issues still exist:

[0004] In this technical solution, water flows out from the nozzle. However, due to the limited number of nozzles and the limited diffusion range of the sprayed water, the contact area between the sprayed water and the dust is limited, thus affecting the dust suppression efficiency. Therefore, an improvement has been made. Summary of the Invention

[0005] Based on the technical problems existing in the prior art, the present invention proposes a dust suppression device and method for iron ore transportation.

Both support pipes are connected to the same water spray pipe, which has a dense array of spray nozzles and a connecting head for connecting to a water source. A base is fixed to the bottom of each support pipe. Sleeves are fixedly fitted to both ends of the water spray pipe. A pair of collars are rotatably connected to the water spray pipe. Multiple annularly arranged extension rods are provided on the outer circumference of the collars. A common reflector is positioned between two opposing extension rods. An arc-shaped reflective groove is formed on the side of the reflector closest to the water spray pipe. A connecting assembly is provided between the support pipes and the water spray pipe. A stabilizing assembly is provided on the base.

[0007] Preferably, the reflector is fixedly connected to the extension rod.
