Three-dimensional mixing device for feed production

The invention belongs to the technical field of feed production, and discloses a three-dimensional mixing device for feed production, which comprises a control console, two groups of main shafts are arranged on the front side of the control console, the output shaft ends of the main shafts are connected with a stainless steel mixing barrel through universal rocker arms, and the three-dimensional mixing device further comprises: a grinding assembly arranged inside the stainless steel mixing barrel; wherein the grinding assembly comprises an inner cylinder, a sleeve is arranged in the middle of the inner cylinder, and the inner wall of the sleeve is connected with a long pipe through a connecting shaft. Through overturning of a stainless steel mixing barrel, when a counterweight ball faces downwards, the gravity of the counterweight ball can pull a movable rod downwards, and the movable rod moves to drive a first clamping plate to move downwards along the inner side of a through opening through a connecting fra
