[0029] When the device is used, the delivery pump 5 is turned on to deliver the feed raw materials to be mixed to the feed hopper 2 through the feeding pipe 4, and then the first motor 13 is turned on, and the first motor 13 is used to drive the driving gear 11 to rotate, so that the driving gear 11 drives the first crushing roller 9 to rotate. During the rotation process, the driving gear 11 drives the second crushing roller 10 to rotate synchronously with the driven gear 12 meshing with it, so that the added feed is crushed, and the crushed feed falls into the premixing box 1. At the same time, the second motor 16 is turned on to drive the stirring rod 15 to rotate, so that the stirring rod 15 stirs and mixes the feed. After mixing, the discharge baffle 17 is opened to take out the feed.
