[0002] With the continuous development of coal mining technology, the safety and efficiency of underground operations have received increasing attention. Coal mining is an industry full of challenges and complexity, in which the cleaning of the inner wall of the coal bunker is a vital link. As a key facility for coal storage and transportation, the inner wall of the coal bunker is often prone to accumulation of coal dust and coal blocks, which not only affects the fluidity of coal, but may also cause blockage, posing a hidden danger to the safe production and efficient operation of coal mines.

[0003] During the transportation of coal in the coal bunker, due to the fluidity, humidity and airflow of the particles, backflow is prone to occur. When the cleaning device is working, these backflow coal particles can easily enter the key parts of the device, such as nozzles or pipes, thereby causing blockage. Once blockage occurs, it will not only affect the normal operation of the cleaning device and reduce the cleaning effect, but may also cause damage to the device itself and increase the cost of maintenance and replacement. Therefore, we need to propose an underground anti-blocking coal louver nozzle. Summary of the invention
