A discharge port 18 is arranged on the base 1, and a blocking plate 19 is slidably installed on the discharge port 18. When in use, the connecting rod 6 can be driven to rotate by starting the driving motor 5. The connecting rod 6 will drive the mounting ball 10 through the driving rod 7 to apply an outward thrust to the inner wall of the screen barrel 3, so that the screen barrel 3 rotates and shakes outward with the rotating ball 14 as the axis point. The controlled-release fertilizer in the screen barrel 3 will be screened through the screen hole 12 by its own gravity as the screen barrel 3 shakes, thereby completing the screening of fertilizer uniformity, and the fertilizer larger than the aperture of the screen hole 12 will be retained in the screen barrel 3. After a certain amount of accumulation, the fertilizer in the screen barrel 3 is taken out, and the screening is continued after secondary processing, so as to ensure that the size of the fertilizer particles after screening is similar and the particles are uniform.
