Description

Technical Field

[0001] The present application relates to the field of dredging equipment, and in particular to a river dredging device. Background Art

[0002] Silt removers are used to clear the silt accumulation at the bottom of the river and are often used for river regulation. The current silt removers use a float to float on the water surface. The machine body on the top of the float is started to control the operation of the water pump. The silt at the bottom of the float is extracted by the water pump and transported to the filtering device with the help of a pipe. After the silt is filtered, the clean water inside is discharged back to its original place, and the filtered impurities are used as fertilizer.

[0003] With regard to the above-mentioned related technologies, the inventor believes that conventional water pumps are often used in environments with a lot of silt. Since plants are easy to grow inside the silt and the position of the water pump needs to be moved, when the water pump is pumping silt, the plant roots are easily drawn into the water pump, causing the water pump to be blocked, requiring staff to spend a lot of time to deal with it.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
