A controller 15 is installed on one side of the screening box 1 through a fixing bolt, and a screening drum 2 is installed in the screening box 1 through a bearing 16 and a rotating shaft 17. A feed port 14 is opened on the top of the screening box 1, and a feed drum 18 is installed on the screening drum 2, and the feed drum 18 is an openable and closable feed drum. A motor 13 is installed on one end of a rotating shaft 17 through a coupling, and the body of the motor 13 is installed on the screening box 1 through a fixing bolt, and the bottom of the screening drum 2 is movable. A first screening net 3 is dynamically installed, and a first vibration motor 11 is installed at the bottom of the first screening net 3. Under the joint action of the screening cylinder 2, the motor 13, the bearing 16 and the rotating shaft 17, the fertilizer entering the screening cylinder 2 can be initially screened, and the screened fertilizer is screened for a second time under the action of the first vibration motor 11 and the first screening net 3, and under the joint action of the first discharge port 19 and the first blocking plate 9, the fertilizer that has not been screened on the first screening net 3 can be discharged from the screening box 1, and under the action of the feed cylinder 18 and the motor 13, the qualified fertilizer that has not been screened out in the screening cylinder 2 can also be poured onto the first screening net 3, and finally discharged from the screening box 1 through the first discharge port;

[0027] A first discharge port 19 is provided at the bottom end of the first screening net 3, a first electric push rod 10 is installed on one side of the screening box 1 through a fixed plate, one end of the first electric push rod 10 is fixedly connected to a first blocking plate 9, and the first blocking plate 9 is located on one side of the first discharge port 19, and the first discharge port 19 is opened on the screening box 1, a second screening net 8 is installed below the first screening net 3, and a second vibration motor 12 is installed at the bottom of the second screening net 8, and both ends of the first screening net and the second screening net are installed in the inner part of the screening box through two movable blocks and a pin shaft. On the wall, a second discharge port 6 is arranged at the bottom end of the second screening net 8, and the second discharge port 6 is opened on the screening box 1, and a second electric push rod 4 is installed on one side of the screening box 1 through a fixed plate, and a second sealing plate 5 is fixedly connected to one end of the second electric push rod 4, and the second sealing plate 5 is located on one side of the second discharge port 6.

[0028] The working principle of the utility model is as follows: when in use, the fertilizer enters the screening cylinder 2 through the feed port 14 and the opened feed cylinder 18. After the fertilizer reaches a certain amount, the cover plate on the feed cylinder 18 is closed and locked. Subsequently, the controller 15 controls the motor 13, the first vibration motor 11 and the second vibration motor 12 to work. The motor 13 works to rotate the screening cylinder 2. During the rotation process, the fertilizer that does not meet the specifications or the fertilizer that is smaller than the aperture of the screening cylinder 2 is screened onto the first screening net 3. Under the action of the first vibration motor 11, the fertilizer that does not meet the aperture of the first screening net 3 is screened onto the second screening net 8. Under the action of the second vibration motor 12, the fertilizer that does not meet the aperture of the second screening net 8 is screened out of the screening box 1.

[0029] After a period of time, the controller 15 controls the first electric push rod 10 to move up with the first blocking plate 9 to allow the first discharge port to leak out, and the controller 15 controls the second electric push rod 4 to move up with the second blocking plate 5 to open the second discharge port, so that fertilizers of different particle sizes that do not meet the specifications can be collected from the first discharge port and the second discharge port respectively;

[0030] Finally, the cover plate on the feed cylinder 18 is opened, and the motor 13 drives the screening cylinder 2 to rotate so that the screening cylinder 2 faces downward, and the qualified fertilizers that meet the specifications are discharged from the screening box 1 through the first screening net 3, thereby obtaining qualified fertilizers.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
