Technical Field

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

[0002] The silt deposits in the ditches and rivers in towns have not been treated in a timely manner over the years, resulting in the scrapping of some water conservancy facilities. Once a flood occurs, serious consequences will occur. Therefore, the ditches and rivers in towns and other water conservancy projects need to use silt removal devices to regularly remove silt to ensure the smooth flow of waterways.

[0003] Reference authorization announcement number CN108755807A discloses a hydraulic silt removal device, which drives the screw shaft and the rotating cylinder to rotate through the rotation of the motor, so that the silt cut by the silt cutting knife is transported upward in the rotating cylinder, and the silt is transported from the silt transport channel to the silt storage bin of the ship body through the silt outlet hole and the silt temporary storage box at the upper end of the rotating cylinder. In this way, the silt removal device can realize the working mode of excavating and transporting the silt with high viscosity or even agglomerated silt out of the river channel, and can timely and effectively clean the silt sediment in the river channel.

[0004] However, the above-mentioned silt removal device has a limited coverage area due to the limited range of the bottom end of the rotating cylinder, resulting in a limited silt removal area and inability to perform large-scale silt removal.
