Hydraulic double-gun free switching type coke knocker

The invention relates to a hydraulic double-gun free switching type coke knocker. The hydraulic double-gun free switching type coke knocker comprises a tool joint, a cylinder body, shoot guns and a conical body, wherein the tool joint is fixedly installed at the upper end of the cylinder body, the conical body is fixedly installed at the lower end of the cylinder body to guide the coke knocker to rotate stably for downward drilling, the two shoot guns are installed on the bottom of the cylinder body and incline downwards in the mode of penetrating through a base plate of the cylinder body from a cavity of the cylinder body, and a partition board is arranged between the two shoot guns in the cavity of the cylinder body; the two shoot guns are symmetrically arranged and intersect in the cavity of the cylinder body, the water inlet ends of the shoot guns are beyond the center axis of the cylinder body, the partition board is vertically fixed in the cylinder body, and the plane of the partition board is parallel to the center axes of the two shoot guns. The hydraulic double-gun free switching type coke knocker is simple in structure, convenient to operate and maintain, stable in operation, efficient, and capable of saving electricity and water. Each shoot gun serves as a drilling shoot gun as well as a coke cutting shoot gun, drilling and coke cutting can be switched freely without the need of returning water pressure back to zero, the coke knocker does not need to be lifted out of a tower, and decoking capacity is high.
