The overall sterilization method:

the first roller driving motor 20 and the second roller driving motor 27 respectively and independently control the rotating speed and the rotating direction of the first roller 21 and the second roller 26, when the rotating speed and the rotating direction of the first roller 21 and the second roller 26 are the same, the conical ring-shaped shell wall 15 supported by the plurality of universal wheels 16 can make forward linear walking motion on the pigsty ground 60, and when the rotating speed of the first roller 21 and the rotating direction of the second roller 26 are the same but the rotating directions are opposite, the conical ring-shaped shell wall 15 supported by the plurality of universal wheels 16 can horizontally rotate on the pigsty ground 60 in situ; when the rotating speeds of the first roller 21 and the second roller 26 are different, the conical ring-shaped shell wall 15 supported by the universal wheels 16 makes horizontal curved walking motion on the piggery ground 60; so that the conical ring-shaped shell wall 15 can make any horizontal movement above the pigsty floor 60; so that the annular flame outlet 25 can reach the upper part of any position of the ground 60 of the pigsty;

the combustion flame generated by the ethanol combustion unit is continuously sprayed downwards to the pigsty ground 60 through the annular flame spray port 25, the flame sprayed downwards from the annular flame spray port 25 finally clings to the pigsty ground 60 through the flame overflow gap 0 to overflow in all directions, and then the pigsty ground 60 is heated and burned, so that the local quick burning and sterilizing effect on the pigsty ground 60 is realized;

meanwhile, the first roller driving motor 20 and the second roller driving motor 27 are remotely controlled, so that the conical ring-shaped shell wall 15 supported by the plurality of universal wheels 16 continuously and slowly moves and translates on the pigsty ground 60, the area passed by the annular flame ejection port 25 on the lower side of the conical ring-shaped shell wall 15 completely covers any position of the pigsty ground 60, and the pigsty ground 60 is burnt and sterilized at any position once.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
