[0027] Working principle: This equipment is a raw coal crushing and transportation device.

The multiple working blocks 9 cooperate with the reinforcing block 12 through the multiple limit blocks 11 and the multiple pins 2 14. Here, the multiple pins 2 14 are also interference fit, so when the multiple working blocks 9 rotate, the multiple crushing blades 13 can be driven to rotate together to crush the raw coal. When one of the crushing blades 13 is damaged, the pin 2 14 on the damaged crushing blade 13 is removed, and then the damaged crushing blade 13 can be replaced.
