Comprehensive matching device and method for large-scale pig raising

The invention discloses a comprehensive matching device for large-scale pig raising, which comprises a wall body and a fermentation unit, and the fermentation unit is arranged on the inner side of the wall body; a traction rail is fixedly arranged on the top of the wall body, and winding pieces are arranged on the side portion of the traction rail and in the wall body. By starting a driving source at the top of a winding piece on the inner side of a traction rail, the driving source is driven by a driving bevel gear and a driven bevel gear in a transmission cavity, so that the driven bevel gear drives a driving winding drum to rotate through a driving shaft, and the driving winding drum winds lifting ropes on the outer sides of a primary fermentation plate and a secondary fermentation plate; the lifting rope pulls the stretching plate, so that the first-stage fermentation plate and the second-stage fermentation plate are gradually lifted and closed under the cooperation of the rolling wheel ...
