[0002] A continuous miner is a comprehensive tunneling and short-wall mining equipment used for mining operations of coal mines and other mineral resources. When carrying out mining operations, it is necessary to install a spray device on the top of the continuous miner to spray and reduce dust in the mine.

[0003] After searching, the announcement number is CN217950356U, and the name is a utility model for a dust reduction device for a mining anchoring continuous mining machine, which includes a material box, a foam generating assembly and a foam nozzle. Through research and analysis, it is found that although it has the advantages of being able to cover the dust source seamlessly during use and fundamentally prevent the dust from spreading outward, etc., it still has the following disadvantages to a certain extent.

[0004] For example, the device does not have an adjustment function. During use, the surface of the mounting frame has only one row of nozzles, which makes it impossible to increase the spray range according to actual usage, resulting in an insufficient spray area, which in turn affects the dust reduction efficiency. In order to solve the above technical problems, we have designed a long-distance external spray device for continuous miners. Utility Model Content
