The invention belongs to the technical field of animal husbandry, and in particular relates to a pasture processing device for animal husbandry breeding. The device comprises a cleaning pool, a dryingbox and a crusher, wherein the crusher is arranged on one side of the cleaning pool; one end of the drying box is arranged above the crusher; the other end of the drying box is arranged above the cleaning pool; a first driving roller and a driven roller are arranged in the cleaning pool; and a first transmission belt sleeves the outside of the first driving roller and the driven roller. The firsttransmission belt mounted outside the first driving roller and the driven roller is convenient for the first driving roller to driving the first transmission belt to rotate in the cleaning pool; meanwhile, a poking rod fixed on the surface of the first transmission belt is convenient for the poking rod to pushing the pasture in the cleaning pool to move; and meanwhile, a pressure rod arranged onthe output shaft of a hydraulic cylinder is convenient for a pressure rod to hammer the pasture during cleaning, so that the cleaning efficiency of the pressure in the cleaning pool is improved.
