At this time, the servo motor 3 drives the rotating disc 5 to rotate, and drives the stirring rod 17 to rotate through the rotating shaft 16, thereby stirring the ground fertilizer, and at the same time, the scraper 18 moves on the inner wall of the mixing drum 14 to scrape off the fertilizer attached to the inner wall to ensure that the fertilizer is stirred evenly. After the stirring is completed, the feeding valve 20 is opened, and the screw conveyor 19 rotates to output the fertilizer from the bottom side of the mixing drum 14, thereby completing the stirring process, so that the stirring device can be applied to fertilizers of different forms, and solves the problem that the stirring device can only stir dry fertilizers and has a small scope of application.
