The invention discloses a desilting structure and a
hydraulic engineering desilting device and belongs to the technical field of
hydraulic engineering. The desilting structure comprises a bucket bodyand prodding claws. The bucket body comprises a feeding portion, a connecting portion and a
silt storage portion which are connected in sequence. The bottom of the feeding portion is arranged obliquely. The bottom of the
silt storage portion is arranged horizontally. The highest end position of the feeding portion and the
silt storage portion are connected through the connecting portion. The prodding claws are fixed to a drum. The multiple prodding claws are distributed in the radial and circumferential directions of the drum. A gap exists between every two adjacent prodding claws. The prodding claws are each of an L-shaped structure. The outer edges of the prodding claws are opposite to the feeding portion. An
impurity portion is arranged on the upper portion of the silt storage portion.An oblique partition plate is arranged between the
impurity portion and the silt storage portion. The top end of the partition plate is opposite to the outer edges of the prodding claws. The desiltingstructure and the
hydraulic engineering desilting device have the beneficial effects that when desilting is performed, silt is separated from stones, large-size impurities and the like inside, separated storage is achieved, the stones, large-size impurities and the like in the silt are prevented from damaging equipment or the device in the moving process, and the reliability is high.
