[0023] The rotating assembly includes a cam 13 fixedly mounted on the rotating shaft 18, a horizontal plate 14 fixedly connected to the rotating rod 16, the cam 13 is arranged between the horizontal plate 14 and the vertical plate 12, a first spring 11 fixedly connected to the vertical plate 12, the first spring 11 is fixedly connected to the surface of the screening frame 9, each L-shaped plate 4 is fixedly connected to a second spring 15, the second spring 15 is fixedly connected to the surface of the screening frame 9, a torsion spring 17 is sleeved on the rotating rod 16, one end of the torsion spring 17 is fixedly connected to the rotating rod 16, and the other end of the torsion spring 17 is fixedly connected to the ear plate 5.

[0024] During the rotation of the cam 13, it will squeeze and separate from the vertical plate 12 and the horizontal plate 14 in sequence. When the cam 13 squeezes the vertical plate 12, the first screen 8 slides relative to the screening frame 9 at the same time. When the cam 13 squeezes the horizontal plate 14, the rotating rod 16 and the squeezing block 3 deflect at the same time, and the torsion spring 17 is deformed. During the rotation of the squeezing block 3, one end thereof will rotate against the surface of the L-shaped plate 4. Under the elastic force of the second spring 15, a second screen 2 will move toward the screening frame 9. Under the squeezing action of the squeezing block 3 , the other second screen 2 will move away from the screening frame 9. A rectangular opening is provided on the back of the screening frame 9, and a cover plate 10 is clamped in the rectangular opening. A discharge port is provided on one side of the screening frame 9, and a sealing plate 19 is clamped in the discharge port. The sealing plate 19 is manually removed from the discharge port, and then the servo motor drives the support column 7 to rotate, and the screening frame 9 is deflected at the same time. The fertilizer on the first screen 8 will be discharged onto the conveyor belt 6 through the discharge port, and the cover plate 10 is removed from the rectangular opening to facilitate the removal of the fertilizer on the second screen 2 below.

[0025] In the present invention, when in use, the motor drives the rotating shaft 18 to rotate at the same time, and then the fertilizer particles that need to be fed and screened are poured into the interior of the screening frame 9 from the top, and the fertilizer will first fall onto the second screen 2 at the top. The sieve holes on the two second screens 2 and the first screen 8 are of different sizes. The sieve holes on the second screen 2 at the top are the largest, the sieve holes on the first screen 8 are larger, and the sieve holes on the second screen 2 at the bottom are the smallest. The rotation of the rotating shaft 18 will drive the cam 13 to rotate together, and the rotation of the cam 13 will Squeeze and detach the vertical plate 12 and the horizontal plate 14. When the cam 13 squeezes the vertical plate 12, the first screen 8 slides relative to the screening frame 9 at the same time. When the cam 13 squeezes the horizontal plate 14, the rotating rod 16 and the squeezing block 3 deflect at the same time. During the rotation of the squeezing block 3, one end thereof will rotate against the surface of the L-shaped plate 4. Under the elastic force of the second spring 15, a second screen 2 will move toward the screening frame 9. Under the squeezing action of the squeezing block 3, the other second screen 2 will move away from the screening frame 9.

[0026] During the rotation of the cam 13, the first screen 8 and the two second screens 2 can be moved back and forth. The first screen 8 and the two second screens 2 have good sealing when connected to the screening frame 9, which can effectively prevent the fertilizer from leaking out when the first screen 8 and the two second screens 2 move. During the back and forth movement of the first screen 8 and the two second screens 2, the fertilizer can be screened. When the screening is completed, the sealing plate 19 is manually taken out from the discharge port, and then the servo motor drives the support column 7 to rotate, and the screening frame 9 is deflected at the same time. The fertilizer on the first screen 8 will be discharged through the discharge port onto the conveyor belt 6, and the motor drives the conveyor belt 6 to convey it, so that the fertilizer can be fed. The fertilizer can be screened before feeding, and there is no need to screen the fertilizer separately after feeding. The operation is relatively quick and convenient, the work efficiency is high, and it is conducive to the use of the feeding device.

[0027] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.
