[0026] When the coal is transported through the coal falling pipe, the driving motor 6 is started to drive the rotating shaft 5 to rotate. In the process of rotating, the rotating shaft 5 drives the rotating rod 3 to rotate on the support 2 through the transmission relationship between the first bevel gear 7 and the second bevel gear 8, and then drives the plurality of stirring rods 4 to rotate around the rotating rod 3 through the rotating rod 3. In the process of rotating, the stirring rods 4 can drive the coal at the outlet section of the pipeline 1 to continuously roll, effectively avoiding the coal in the pipeline 1 from blocking the outlet section, so that the coal unloading is more smooth, and the production is more convenient.
