The invention discloses a dredging device of a sewer well. According to the technical scheme, the dredging device of the sewer well is characterized by comprising a shell. The shell comprises a vertically throughout inner annular pipe and an outer annular pipe arranged on the outer side of the inner annular pipe in a sleeving mode, wherein the bottom of the inner annular pipe is an opening shaped like a horn mouth; the outwards extending edge of the opening is connected with the bottom of the outer annular pipe; a sediment cavity is arranged between the inner annular pipe and the outer annular pipe; a sealed top cover is arranged on the upper portion of the outer annular pipe; a gap where sewage flows is reserved between the inner annular pipe and the top cover; filtering holes for filtering out silt are formed in the lateral surface of the outer annular pipe; a submarine stirring and water pumping device used for stirring and driving sewage, sludge and gravels to enter the sediment cavity is arranged in the inner annular pipe. The dredging device of the sewer well can automatically filter sludge and gravels only by being put in the sewer well and then started without the need for workers to enter the sewer well. The work environment of sanitation workers is improved. Labor is saved. Great convenience is brought to work.
