Kiln cleaning machine

The invention discloses a kiln cleaning machine which comprises a guide accelerating pipe, one end of the guide accelerating pipe is provided with a kiln door connecting assembly in butt joint with a kiln door, and the other end of the guide accelerating pipe is provided with a high-pressure air supply assembly, a filling assembly and a filling support assembly which are connected with the guide accelerating pipe. According to the device, the lead column is placed through the filling assembly, the lead column is guided to the accelerating pipe through the high-pressure air supply assembly to be injected into the kiln door, so that coke in the kiln head is cleaned, compared with manual coke cleaning, formed rings can be cleaned under the condition of normal calcining of the kiln, the influence on calcining is very small, the cleaning efficiency is high, and the production period of the rotary kiln is prolonged.
