Dredging device for slag hole

The invention discloses a slag hole dredging device which comprises a driving unit, a fixed assembly, an eccentric assembly and a reciprocating assembly. The dredging unit comprises an adjusting assembly, a rod body assembly and a power assembly. The dredging device has the beneficial effects that the driving unit and the dredging unit are arranged, the eccentric assembly, the reciprocating assembly and the power assembly are matched to enable the rod body assembly to adjust the height during reciprocating motion so as to dredge the blocked slag outlet, and the blockage position of the slag outlet is adjusted to adapt to equipment of different specifications; in addition, the situation that workers are injured by high-temperature coke residues can be prevented, the situation that a large amount of manpower is wasted due to the fact that the treatment frequency is too frequent and the treatment process is troublesome is avoided, and the dredging angle is changed through cooperation of an adjusting assembly and
