The present invention discloses a novel agricultural feed mixing device. The novel agricultural feed mixing device comprises a material feeding device and a mixing device. Left and right sides of an upper end of a mixing cylinder are respectively provided with a first material feeding hopper and a second material feeding hopper, inner bottom ends of the first material feeding hopper and the secondmaterial feeding hopper are respectively provided with a first electronic scale and a second electronic scale, and the first electronic scale and the second electronic scale are respectively providedwith a first electromagnetic valve and a second electromagnetic valve; a rotary shaft is horizontally arranged at a lower side inside the mixing cylinder and a right end of the rotary shaft is connected with a motor; a bottom plate is arranged under the mixing cylinder via two damping devices and two supporting devices are arranged on a lower end surface of the bottom plate; and each of the supporting device comprises one supporting column and one floor foot, the supporting columns are vertically arranged on the lower end surface of the bottom plate, and the floor feet are fixedly arranged onlower sides of the supporting columns. The novel agricultural feed mixing device can realize quantitative material feeding, improves working efficiency, uses stirring rods and stirring through-holesto perform stirring, uses two material turning plates to raise feeds at a bottom part to conduct mixing, and is good in mixing effects and high in uniformity.
