Cutting Head for the dredged soil, Cutting and Suction Dredge with the use of the Cutting Head and cutting head to clean the ground.

摘要

The application relates to a Cutting Head for dredged soil under water. The Cutting head is suitable for be in rotation about a Central Axis to the scale of a Cutter and Suction to be moved through the soil lateral Movement in a sweep.The Cutting Head comprises a Ring base, a Central Vertex located some distance in the direction of the Central Axis from the Ring base, and a Plurality of support Arms which extend from the base to the Vertex ring central, where is located a Passage Opening between the Support arm and the cutting tools are axisimu00e9tricas,At least at its Outer End. The Cutting Head invented has Greater Efficiency, particularly in soils with an unconfined compressive strength (UCS), axial according to the acronym in English) of at least 50 MPa.
