The utility model relates to a mixing device for feed production, which comprises a base, an adding mechanism arranged at the top of the base and a mixing mechanism arranged at the top of the base, the adding mechanism comprises a side plate fixedly connected to the top of the base, one end of the side plate is hinged with a first electric push rod, and one end of the first electric push rod is hinged with a first storage
barrel. The first storage
barrel is hinged to the base, and one end of the first storage
barrel is fixedly connected with a first adding hopper. The mixing device for feed production is provided with a structure convenient for adding additives, a traditional tedious mode of manually adding the additives by means of additional tools is abandoned, workers do not need to spend a lot of time and energy to carry out complex adding operation, and the additives can be added only through a specific adding channel or connector of the device. The additive can be easily added into the feed only by adding the additive into the feed, so that the adding time of the additive is greatly shortened, the efficiency of the whole feed production process is improved, and particularly in large-scale feed production, the yield can be remarkably increased, and the market demand is met.
