The invention relates to an overturning and throwing machine for producing an organic fertilizer and a nutritional matrix. The overturning and throwing machine comprises a frame, a walking mechanism arranged behind the frame and an overturning and throwing mechanism arranged at the lower part of the frame, the walking mechanism is driven by a transmission motor, the overturning and throwing mechanism is driven by an overturning and throwing motor, the overturning and throwing mechanism comprises an overturning and throwing shaft, a plurality of overturning and throwing cutter discs arranged on the overturning and throwing shaft, and overturning and throwing shaft sleeves, the overturning and throwing cutter discs and the overturning and throwing shaft sleeves are alternately distributed, every overturning and throwing cutter disc is provided with a cutter shaft, and a cutter head is arranged at the upper end of every cutter shaft. Compared with overturning and throwing machines in the prior art, the overturning and throwing machine has the following advantages: the diameter of the overturning and throwing cutter discs is adjustable, so the overturning and throwing at different depths are realized according to different material depths; the length of the cutter shafts is adjustable, and can be combined with the diameter of the cutter discs to generate different overturning and throwing depths; the length of the shaft sleeves is adjustable, so the width of an overturning and throwing gap can be adjusted according to the kind of the material, and different shaft sleeve lengths can be set according to the kind and the water content of a fermentation material during the installation of the overturning and throwing shaft; and the type of the cutter heads is adjustable, so different cutter head types can be set according to the characteristics of different fermentation materials.
