Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction equipment technology, specifically to a water conservancy construction dredging device. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature, aiming to achieve the goals of mitigating harm and promoting benefits. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production.

[0003] Typically, dredging projects in medium-sized rivers are carried out using small-scale dredging equipment. This equipment is placed on the riverbed and pumps are used to extract the silt. The silt is then transported to the riverbank through pipelines. However, existing dredging and cleaning devices used in water conservancy projects cannot control the moisture content of the silt during collection. When the moisture content is low, the silt easily adheres to the pipes, causing blockages that require manual cleaning, making them inconvenient to use.

[0004] To address the aforementioned technical problems, this application proposes a dredging device for water conservancy construction. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that the water content of silt cannot be controlled. When the water content is low, the silt easily adheres to the pipe fittings, causing blockage.
