The invention discloses a high-bed fermentation-type pig raising system device. The device comprises a roof layer, a feeding layer and a fermentation layer, three electric skylights are installed at the top of the roof layer in sequence, a rainwater collection device is installed between every two adjacent electric skylights, several solar panels are installed at the two sides of the roof layer, the bottom of the roof layer is fixedly connected with the top of the feeding layer, two negative pressure draught fans are installed in both sides of the feeding layer, an iron door is arranged in the middle of one side of the feeding layer, and stairs are installed at one side of the iron door. Through the arrangement of the electric skylights, the negative pressure draught fans and electric roller shutters, the air circulation inside the feeding layer can be strengthened, and cooling and ventilation are achieved; through the arrangement of an electric feeding trolley and wheel rails, electric feeding can be achieved, the labor investment is reduced, and the cost is saved; through the arrangement of an automatic water supply device, the purpose that water is introduced into a drinking water tank in an electric mode can be achieved, and the high-bed fermentation-type pig raising system device is more convenient and efficient to use.
