Inert gas protection device for bone meal placement

The utility model relates to the technical field of bone meal placement, in particular to an inert gas protection device for bone meal placement, which comprises a shell, and fixing plates are fixedly connected to two sides of the shell; the placing mechanism capable of uniformly mixing bone meal with inert gas to prevent the bone meal from going bad is arranged on the inner wall of the shell; the air pump can pump out air in the shell to enable the interior of the shell to be in a vacuum state, the gas conveyor conveys inert gas into the shell to protect bone meal, the motor drives the two stirring rods to stir the bone meal, the bone meal and the inert gas are evenly mixed together, and the protection effect of the inert gas on the bone meal is improved. A second stirring rod can also prevent bone meal from blocking the pipeline during discharging, a cross rod and a first stirring rod are matched to improve the stirring effect on the bone meal, a concentration detector can detect inert gas in the shell, the
