The invention discloses automatic mechanical equipment for feed stirring. The automatic mechanical equipment comprises a crushing structure, a bracket, a mixing structure and a batching structure, thecrushing structure is composed of a crushing frame, a magnetic separation frame, a screening frame, a material guiding structure and a conveying structure. The crushing frame, the magnetic separationframe, the screening frame and the material guiding structure are sequentially connected in a through a welding mode from top to bottom. The conveying structure is obliquely fixed to the bottom end of the material guiding structure, the conveying structure is connected with the material guiding structure in a penetrating mode, the bracket is arranged on one side of the crushing frame, the mixingstructure and the batching structure are arranged on the bracket, and the crushing structure and the batching structure are arranged on the two sides of the mixing structure respectively. The equipment is convenient for automatic mixing of a feed and traditional manually treated fresh forage, so that the use amount of workers is reduced, the labor intensity is reduced, the discharge efficiency isimproved, the labor cost in feed processing is reduced, the feed stirring treatment efficiency is improved, accurate matching between the feed and additives is facilitated, and the feed mixing and proportioning precision is improved.
