Built-in coal bunker dredging structure

The invention relates to the technical field of coal bunker dredging, and discloses a built-in coal bunker dredging structure which comprises a dredging structure body, the dredging structure body comprises a moving dredging mechanism, and the moving dredging mechanism moves on the inner side of a coal bunker for dredging; and the multi-angle adjusting dredging mechanism is connected to the inner side of the movable dredging mechanism. The working motor works, the working motor drives the rotating rod to rotate, the dredging clamping teeth connected to the surface of the rotating rod rotate synchronously, and the dredging clamping teeth crush coal briquettes, so that the coal briquettes are dredged, and the interior of a coal bunker is prevented from being blocked; the installation support synchronously contracts and swings, the axis is adjusted, so that the telescopic rod is pulled to conduct reciprocating telescopic operation, the dredging clamping teeth conduct reciprocating transverse swinging and recipro
