Technical Field

[0001] This utility model relates to the technical field of spray dust suppression devices, specifically a coal mine dust suppression spray device. Background Technology

[0002] During the coal mining and transportation process, a large amount of dust is generated and dispersed in the working environment. Especially during the transportation of coal blocks, a large amount of dust is generated when the coal blocks are loaded onto the conveying mechanism, at the loading end and during the conveying process. In order to reduce the dispersion of dust, corresponding coal mine dust suppression spray devices are used.

To address these issues, a coal mine dust suppression spray device is proposed. Utility Model Content
