The silt discharging device comprises a fall chamber with a cavity, an opening is formed in the top of the fall chamber, the fall chamber is arranged at the bottom of the convex bank of the channel and communicated with the channel through the opening, and the opening direction of the fall chamber is consistent with the direction of water flow in the channel; the bottom of the fall chamber is communicated with a rotational flow pipe, the tail end of the rotational flow pipe is communicated with a sand discharging bent pipe, and the sand discharging bent pipe and the rotational flow pipe are located on the same horizontal plane and are perpendicular. A flow guide ridge is arranged above the fall chamber and fixed to the concave bank of the channel. A fall chamber is arranged in a channel convex bank silt easy-to-deposit area, so that bed load silt to be deposited in a bent section and silt transferred to the convex bank due to transverse circulation flow enter a rotational flow pipe along with a small amount o
