Description

Technical Field

[0001] This invention relates to the field of river management and dredging technology, and in particular to a device for treating, purifying and dredging river sludge. Background Technology

[0002] If river silt and debris are not cleaned up for a long time, they will emit a foul odor and cause inconvenience to people's lives. In addition, scouring and siltation often occur in natural rivers, which can easily lead to water disasters and hinder water conservancy development.

[0003] To ensure smooth water flow in the river, dredging is necessary. The dredging process involves extensive use of edge-mounted excavators, but these methods are insufficient for thorough cleaning; large cutter suction dredgers cannot access typical river channels. Furthermore, the presence of aquatic vegetation on the water surface during dredging makes movement difficult, necessitating multiple dredging operations, which hinders rapid river clearing. Manual dredging is also cumbersome.

[0004] In the prior art, CN202110783318.1 provides a river dredging device, which includes a suspension mechanism and a gripper mechanism. A first trigger mechanism is installed on the connecting plate to control the gripping depth of the gripper mechanism, preventing excessive gripping depth that could lead to excessive gripping volume and affect the lifespan of the gripper mechanism. However, the gripper is slow in dredging efficiency, and the dredging position is difficult to control, resulting in missed areas and low dredging efficiency. Therefore, this invention designs a sludge purification device capable of both dredging with aquatic plants and removing silt, thereby achieving the technical objective of dredging and purification.
