[0036] Working principle:

[0037] When the granular fertilizer made by the granular fertilizer prilling machine is used in the granular fertilizer prilling machine screen residue recovery mechanism, the granular fertilizer can fall into the inside of the screening cylinder 1 through the feed hopper 2. At this time, the control panel is used to make the driving motor 12 work. The output end of the driving motor 12 drives the two groups of stirring leaves 9 to rotate through the connecting shaft 7 and the multiple groups of connecting rods 8. The two groups of stirring leaves 9 can stir the granular fertilizer. The granular fertilizer that does not meet the size can fall into the inside of the discharge hopper 4 through the arc-shaped screen 3. When it is necessary to remove the granular fertilizer inside the screening cylinder 1, the control panel is used to make the output ends of the two groups of first self-locking reversible motors rotate in the same direction through the synchronous controller. At this time, one group of winding discs 14 unwinds one group of pull ropes 15, and the other group of winding discs 14 winds the other group of pull ropes 15. At the same time, the two groups of piston blocks 6 move synchronously. Finally, the granular fertilizer inside the screening cylinder 1 can be pushed out. Through the arc-shaped filter screen and the piston block 6, the granular fertilizer can be screened multiple times, which improves the use practicality of the granular fertilizer prilling machine screen residue recovery mechanism. At the same time, according to the above operation, the granular fertilizer that does not meet the size can fall into the inside of the discharge hopper 4 through the arc-shaped screen 3. The control panel is used to make the second self-locking reversible motor work. The output end of the second self-locking reversible motor can drive the guide plate 17 to rotate clockwise through the mounting shaft 16. When the guide plate 17 contacts the right group of limiting rods 19, the control panel is used to make the second self-locking reversible motor stop working. At this time, the screen residue entering the distribution box 5 can fall on the inclined guide plate 17. The screen residue finally exits through the right group of discharge pipes 18. The discharged screen residue can fall into the inside of the lower group of collection structures. When the group of collection structures is full of screen residue, the control panel is used to make the output end of the second self-locking reversible motor drive the guide plate 17 to rotate counterclockwise through the mounting shaft 16. When the guide plate 17 contacts the left group of limiting rods 19, the control panel is used to make the second self-locking reversible motor stop working. At this time, the screen residue can be discharged through the left group of discharge pipes 18. The screen residue is discharged alternately through the two groups of discharge pipes 18, which can continuously clean the screen residue inside the two groups of collection structures. Through the setting of the distribution box 5, the cleaning work of the screen residue can be completed without stopping the screening work, which improves the working efficiency of the granular fertilizer prilling machine screen residue recovery mechanism.
