Introduction to Chain Bucket Dredger

One, a chain bucket dredger is a specialized type of ship known for its superior finishing quality after excavation compared to other dredgers. It is highly practical for excavating harbors, anchorages, and foundation trenches of buildings. The chain bucket dredger can挖掘various types of silt, soft clay, sand, and sandy clay. It is commonly used for dredging and clearing operations in water bodies with a high content of rocks, such as rivers, ports, and coastlines. It is widely applied in fields such as water conservancy, navigation, mining, and environmental protection, effectively clearing silt, garbage, and pollutants to maintain waterway navigability and ecological environment.

The primary working principle involves submerging the lower end of the bucket bridge to a certain depth underwater, allowing it to contact the dredging soil layer. Subsequently, the continuous operation of the bucket chain, driven by the upper guide wheel, moves the mud in the buckets, collects it after excavation, and elevates it out of the water with the rotation of the bucket chain, then transports it to the top of the tower. After passing through the upper guide wheel to change direction, the sand and mud inside the buckets fall into the mud well of the bucket tower under their own gravity. The sand and mud are then discharged over the sides of the dredger through the mud chutes. During operation, the chain bucket dredger typically moves slowly on the water surface. The rotating sprockets drive the chain, causing the buckets to rotate, and then lift silt and debris onto the deck, which is then poured into subsequent processing equipment. After necessary processes such as screening and water washing, the material is conveyed and unloaded to designated locations.

Section 3: Chain Bucket Dredgers typically consist of main components such as the hull, cabin, engine room, bucket wheel, and chain bucket system. They can be equipped with various auxiliary devices to meet different operational requirements, such as waterwheel, trommel, pump, and conveyor belts, etc.
