The invention relates to a solid scattered material discharging controlling device. The device comprises a feeding hopper, a scattered material driving device and a discharging controlling device housing. The feeding hopper is externally provided with a vibrator, and a conical guiding hood is arranged in the feeding hopper. The discharging controlling device housing is mainly composed of a scattered material conveying pipe and a scattered material feeding passage which is arranged on the top of the housing, the scattered material conveying pipe is composed of two circular pipes with the same diameter, and the scattered feeding passage is composed of two rectangular pipes. The feeding hopper and the scattered material feeding passage are connected and fixed by a soft connecting flange and ashock-absorbing device. The scattered material driving device is provided with spiral blades and a driving motor, and two groups of the spiral blades are fixed in the scattered material conveying pipe. The device has the advantages that the scattered material in the upper portion of the discharging device can flow approximately as a whole without obvious material flowing deflecting, blocking andnonuniform speed distribution, the device can be operated at a higher temperature, and therefore the continuous and stable movement of the scattered material at a lower flow rate is achieved.
