Feed mixing equipment for pig breeding

The utility model relates to the technical field of pig breeding, in particular to pig breeding feed mixing equipment which comprises a bottom plate, a mixing tank is arranged at the top of the bottom plate, a U-shaped support is fixedly connected to the top of the bottom plate, and a first supporting rod is fixedly connected to the top of the U-shaped support. A first motor works to drive an inclined strut to rotate and drive a second rotating rod to rotate in a concentric-square-shaped notch of a concentric-square-shaped plate, the concentric-square-shaped plate is extruded to drive a rack to move rightwards, a gear rotates and a mixing tank to swing leftwards, and when the second rotating rod rotates to the rear half stroke, the mixing tank swings rightwards; the mixing tank in a swinging state can effectively prevent feed from being deposited on the inner wall of the bottom, so that the feed is uniformly stirred, the feed is discharged through a discharge pipe after stirring is completed, the mixing tank
