Pulverized coal bunker for rotary kiln

The utility model belongs to the technical field of rotary kilns, and particularly relates to a pulverized coal bunker for a rotary kiln, which comprises a shell, a rotor scale is fixedly arranged at the bottom of the shell, the top of the shell is fixedly communicated with a filter box and a cover body, two slots are arranged at the top of the filter box, and inserting plates are movably clamped in the two slots. And the tops of the two inserting plates are fixedly provided with the same cover plate, the top of the cover plate fixedly communicates with a feeding hopper, a fixing groove is formed in one side of each inserting plate, and a groove is formed in the inner wall of one side of each inserting groove. The rotor scale is reasonable in structural design, pulverized coal can be evenly scattered on the side wall of the shell through the rotating umbrella cover, the situation that the pulverized coal directly falls to cause huge impact on the rotor scale and damage the rotor scale is avoided, impurities i
