Feed degradation and fermentation device capable of fully fermenting

The invention discloses a fully-fermented feed degradation and fermentation device, and particularly relates to the technical field of feed degradation, the fully-fermented feed degradation and fermentation device comprises a fermentation barrel, a box body is fixedly connected to the top of the fermentation barrel, and a first groove is formed in the box body. A first movable plate is arranged at one end of a driving shaft, a movable rod is arranged at the top of the first movable plate, a second movable plate is arranged at the top of the movable rod, a first rotating rod is arranged at the top of the second movable plate, and a connecting rod is arranged on the outer wall of the movable rod, so that a rotating shaft can drive a stirring rod to rotate left and right. When the feed resources need to be treated, the feed resources are firstly smashed, the feed resources and a coarse feed degradation agent in the device do not naturally ferment and react, so that the feed resources can degrade and decompose cr
