Description

Technical Field

[0001] The utility model relates to the technical field of silt removal, in particular to a silt removal device for water conservancy construction. Background Art

[0002] The purpose of water conservancy construction is to eliminate water disasters, develop water conservancy, and make full use of water resources and hydropower resources. Its contents include irrigation, drainage, water diversion, flood control, water source protection, soil and water conservation, and improvement of saline-alkali land, swamps, grasslands and deserts. When carrying out water conservancy project construction, it is necessary to dredge the river channel to remove the silt accumulated on the riverbed and ensure the safe development of water conservancy construction projects. When dredging the river channel, using dredging equipment can efficiently complete the dredging operation.

[0003] In a dredging device for water conservancy construction projects proposed in application number 202322132532.8, a silt discharge mechanism is arranged above the filter screen inside the collecting tank. When in use, the driving motor is started to drive the spiral conveying shaft to rotate inside the collecting tank, so that the silt collected in the collecting tank can be transported to one side of the silt discharge port and discharged. At the same time, the spiral conveying shaft is stabilized by a stabilizing frame, so that the silt can be discharged from the inside of the collecting tank conveniently and quickly. There is no need to use other equipment to extract the silt from the top of the collecting tank, which greatly improves the working efficiency of the dredging device during dredging operations in water conservancy construction projects.

[0004] Although the above application has met the user's needs to a certain extent, there are still certain defects in the use process.

When the dredging range needs to be adjusted, either personnel extend the pipeline or personnel reach it through a mobile dredging device, resulting in high labor intensity and low efficiency for personnel to adjust the dredging range.
