The invention belongs to the field of livestock breeding equipment and particularly relates to a pressing prevention piglet protection box for sow farrowing. The pressing prevention piglet protection box comprises a delivering box and a connecting slope. The delivering box is a rectangular box. The upper portion of the box is an open square surface. The bottom of the box is provided with an electric heating panel. Holes are formed in the bottom surface of the box and located below the electric heating panel. The two parallel sidewalls in the box are provided with first hooks. The hooks on the same sidewall are located in the same horizontal line. One sidewall provided with the first hooks is provided with an opening. The lower edge of the opening is flush with the bottom of the box. The connecting slope is in a dustpan shape. The lower bottom surface of the front end of the dustpan-shaped connecting slope is provided with second hooks. The rear end of the dustpan-shaped connecting slope is an open square surface. A connecting beam is arranged between the two sidewalls of the dustpan-shaped connecting slope and located at the rear end of the dustpan-shaped connecting slope. The connecting beam is provided with third hooks. The pressing prevention piglet protection box is simple in structure and convenient to disassemble and assemble, the labor intensity of workers is reduced, and the survival rate of piglets is increased.
