[0030] Working principle: when it is necessary to quantitatively feed coal powder, pour the coal powder into the feeding tank 1 through the feeding port 3, start the motor 6, and the motor 6 drives the gear 8 on the transmission shaft 7 to rotate. The gear 8 is an incomplete gear, which transmits the meshing gear 2 9 at intervals. When the gear 2 9 rotates, it drives the transmission shaft 2 11 to rotate.
