Abstract

The invention relates to a dredging device, in particular to an urban small river dredging ship. The urban small river dredging ship comprises a bridge frame positioned at a stem, a suction and discharge device positioned in a ship cabin and a positioning pile positioned at the stern; an A-shaped rack for hoisting the bridge frame is positioned at the stem; the front end of the bridge frame is connected with a digging cutter through a flange; the suction and discharge device comprises a diesel engine and an integrated mud pump gear box; a driving hydraulic motor connected with the digging cutter is arranged in the bridge frame; the digging cutter is a bucket wheel, a common reamer or an environment-friendly reamer; the bucket wheel has rated buckets or a few buckets; the common reamer is an opened reamer or a closed reamer; and the environment-friendly reamer has multiple knives or a few knives. The urban small river dredging ship can meet the specificity of dredging urban rivers, andcan conveniently dredge, and dig the urban rivers and sail in the urban rivers.

Description

technical field [0001] The invention relates to a dredging device, in particular to a dredging ship for small urban rivers. Background technique [0002] Urban rivers are characterized by intersecting waterways, numerous bridges and sluices, and heavy water transportation. The river garbage in these waters is plentiful and miscellaneous. There are mobile pollutants on the riverbed surface, silt, and highly plastic hard clay that is difficult to excavate. This requires that the dredging ship not only has corresponding construction capabilities, but also has good adaptability to the working conditions during construction. [0003] CN90223590.7 discloses a pond dredging ship, and CN02267671.6 discloses a winch type dredging ship, but these dredging ships have complex structures and large hulls, and are not suitable for dredging and dredging in small urban watersheds , it is difficult to exchange different tools in time according to the construction conditions.
