Mausoleum anti-oxidized oxidization digging device

The utility model relates to an excavating device of ancient tomb, which consists of two to four sections of airproof, pressure-proof and transparent houses. An airproof door is arranged between the houses, and each section of house is provided with an illuminating line, an emission pipe of inert gases and a discharge pipe of indoor air; the surrounding of the house close to the tomb outlet is communicated with the tomb outlet in an airproof manner; beside being provided with the emission pipe of incoming gas and the discharge pipe of indoor air, the section of the house close to the tomb outlet is also provided with an oxygen input pipe and a carbon dioxide discharge pipe for breathing. When in use, the incoming gases are led into the airproof chamber through the emission pipe, and the original oxygen in the chamber is exhausted through the discharge pipe of indoor air, which provides an oxygen-free environment for the chamber, thus the collating and preservation work of the historical relic are conducted un
