A number of stirring rods 23 are fixedly connected to the left and right sides of the rotating rod 13. A number of limiting rods 14 are fixedly connected to the left inner wall of the connecting chamber 3 and the left side of the placement chamber 1. A number of filter plates 9 are fixedly connected inside the placement chamber 1. A first filter screen 10 and a second filter screen 8 are fixedly embedded in the top surface of the two filter plates 9 from top to bottom. A number of discharge troughs 12 are opened on the left side of the placement chamber 1.
[0028] The connecting chamber 3 is a cylinder with a hollow interior and a missing right side. The rotating rod 13 is rotatably connected by a bearing and a mounting plate 22. The two discharge troughs 12 are located on the top of the two filter plates 9 respectively. Multiple limiting rods 14 and multiple stirring rods 23 are located inside the connecting chamber 3. The multiple limiting rods 14 and multiple stirring rods 23 located on the same side are distributed crosswise.
[0029] Specifically, fertilizer enters the interior of the storage chamber 1 and is screened by the first filter screen 10 and the second filter screen 8. Fertilizer retained on the first filter screen 10 and the second filter screen 8 passes through the discharge chute 12 and enters the interior of the connecting chamber 3. The rotating rod 13 rotates, which in turn causes the stirring rod 23 to rotate. Through the cooperation of the stirring rod 23 and the limiting rod 14, the fertilizer is crushed.
[0030] Please see Figures 1 to 3 In this embodiment, the connecting chamber 3 is provided with a discharge assembly for discharging the fertilizer inside. The discharge assembly includes a sealing ring 21, which is fitted onto the outer peripheral wall of the mounting plate 22. A first motor 15 is fixedly installed on the bottom surface of the mounting plate 22. The output shaft of the first motor 15 is fixedly connected to the rotating rod 13.

The fertilizer that has passed through the second filter screen 8 is restricted by the guide chamber 7 and falls downward. Then, it is discharged from the storage chamber 1 by the conveying of the discharge chute 6.
[0036] The working principle of the above embodiments is as follows:
[0037] Fertilizer enters the storage chamber 1. The second motor 18 is started, and the output shaft of the second motor 18 drives the drive rod 2 to rotate, which in turn causes the scraper 11 to rotate. The fertilizer is screened by the first filter screen 10 and the second filter screen 8, and the scraper 11 accelerates the screening efficiency. Fertilizer passing through the second filter screen 8 is restricted by the guide chamber 7 and falls downwards. It is then discharged from the storage chamber 1 by the discharge chute 6.
