[0007] As a technical solution of the utility model, the length of the drill rod is 6300MM, and the drill rod is made of solid 35SiMnMoV material to improve the strength of the drill rod.

[0008] As a technical solution of the utility model, a first mounting groove is provided at the center of the other side of the baffle, and the first mounting groove is designed as a circular structure so that one end of the drill rod can be installed inside the baffle through the first mounting groove.

[0009] As a technical solution of the utility model, a fixing piece is arranged on the outer side of the other side of the baffle close to the first mounting groove, and the fixing piece adopts an annular structure so that the fixing piece can fix the drill rod.

[0010] As a technical solution of the utility model, the drill rod is installed on the inner side of the fixing piece, and the fixing piece and the drill rod are fixed by welding, so that the connection between the fixing piece and the drill rod is more firm.

[0011] Compared with the prior art, the beneficial effect of the utility model is as follows: by setting a second mounting groove inside one side of the baffle, then installing the drill bit assembly in the second mounting groove through the mounting rod, and welding the drill bit assembly to one side of the baffle, so that the drill bit assembly is driven when the baffle rotates, and the iron mouth mud sleeve is replaced by the drill bit at the other end of the drill bit assembly, so that the device for quickly replacing the iron mouth mud sleeve can quickly and effectively replace the mud sleeve online, avoiding workers from working for a long time in the gas area, ensuring the stability of the iron mouth operation, and solving the accident of blast furnace production reduction due to mud sleeve damage.
