Product Detail
Cutter suction dredger head, also known as the cutter head or cutting head, is a critical component of a cutter suction dredger (CSD). It is attached to the front of the dredger and is responsible for loosening and excavating the material from the sea floor during the dredging operation. The cutter head's design and features enable efficient cutting and suction of various types of sediments, such as sand, clay, gravel, and soft rock.
Features of cutter suction dredger head
Shape and Structure: The cutter suction dredger head is typically cylindrical in shape and located at the lowermost part of the dredger's ladder or suction arm.
Cutting Blades: The cutting blades or teeth are designed to be robust and sturdy to withstand the abrasion and impact caused by cutting through the sea floor.
Rotation Mechanism: The cutter suction dredger head is equipped with a powerful hydraulic motor that drives the rotation of the cutting blades. The rotation allows the blades to dig into the sediment, effectively breaking it loose from the sea floor.
Swivel Mechanism: To enhance maneuverability and ensure even wear on the cutting blades, many cutter heads have a swivel mechanism that allows them to rotate horizontally or change their angle during operation.
Suction Inlet: Surrounding the cutting blades, there is a suction inlet or intake area that connects to the suction pipe.
Material Handling: The loosened material is mixed with water to create the slurry, making it easier to transport through the pipeline.
Cutting Depth Control: Cutter suction dredger head can be adjusted to control the cutting depth based on the project's requirements or the characteristics of the seabed material.
The efficiency and effectiveness of a cutter suction dredger largely depend on the design and performance of its cutter head. Proper maintenance and periodic replacement of worn cutting blades are essential to ensure the dredger's continued productivity and performance during dredging operations.
