Biological feed production mixing device

The utility model belongs to the technical field of feed production, and particularly relates to a biological feed production mixing device which comprises a mixing barrel, the top of the mixing barrel is fixedly connected with a support frame; a driving motor is fixedly connected to the middle of the top side of the supporting frame. The output end of the driving motor penetrates through the wall body of the supporting frame and is fixedly connected with a connecting rod. A plurality of groups of stirring rods are fixedly connected to the middle part of the connecting rod; a first material distributing plate is fixedly connected to the inner side wall of the material mixing barrel, and during working, the second material distributing plate is always in a continuous rotating process, so that materials falling between the second material cutting groove and the first material cutting groove are crushed into small-specification chippings by the second material distributing plate, and the materials can be more fu
