After reaching the grate cooler, personnel can turn on the drive motor to drive the fixed rod to rotate through the rotating shaft to break up the falling cement clinker, so as to avoid the accumulation of materials after falling and affecting cooling. After breaking up, the materials are embedded and fixed in the fixed pipe through the bottom end face of the air outlet pipe two, so that the blower is turned on to take in air and then exhausts air through the fixed pipe.
