Pulverized coal weighing device

The utility model relates to a pulverized coal weighing device, which aims to solve the technical problem that the quantitative conveying of a rotor scale is easily influenced due to the large impact force of the current pulverized coal with a certain falling speed, and comprises a rotor scale body, a middle bin is arranged at the feeding end of the rotor scale body, and the pulverized coal weighing device further comprises a buffer structure; the buffer structure is arranged in the middle bin; the buffer structure comprises a fixing ring, a connecting strip and a bearing top tray; the fixing ring is fixedly arranged on the ring wall of the inner cavity of the middle bin; the bottom ends of the three connecting strips are arranged on the fixing ring in an annular array mode through elastic assemblies. The coal powder buffering and speed reducing device has the advantages that coal powder falling from the feeding end of the middle bin impacts on the bearing top disc, and the bearing top disc is driven to move
