When the coal crushing blades 811 crush the coal, the coal splashes inside the coal mill body 1 and can enter the interior of the coal collecting trough 81. When the driving center shaft 5 rotates, it can drive the push block driving ring 84 to rotate synchronously. When the push block driving ring 84 rotates, it can drive the coal push block 82 to reciprocate inside the coal collecting trough 81 through the transmission connection with the push block transmission ring 83.
