The bottom surface of the connecting rod 3 is fixedly connected with the top surface of the support frame 2. The first servo motor 4 is fixedly arranged on one side of the support frame 2 through a support. The rotating shaft of the first servo motor 4 is fixedly connected with the eccentric wheel 5 through the support frame 2. The rotating shaft of the first servo motor 4 is in rotary connection with the support frame 2. The two ends of the first servo motor 4 are each provided with a moving hole 10. The two swing rods 6 are each in sliding connection with the moving hole 10. The screen structure further comprises a second screen 9 and a connecting strip 17. The other end of the two swing rods 6 is fixedly connected with one side of the first screen 8 respectively. The bottom surface of the first screen 8 is fixedly connected with one end of the connecting strip 17 at four corners respectively. The other end of the four connecting strips 17 is fixedly connected with the same second screen 9. The swing rod 6 is in L shape.

[0028] The fertilizer to be screened is poured into the first screen 8. The power supply of the first servo motor 4 is turned on. The first servo motor 4 drives the eccentric wheel 5 to rotate. The end of the eccentric wheel 5 slides in the sliding groove 11. The moving block 7 swings to drive the two swing rods 6 to swing left and right. The two swing rods 6 drive the first screen 8 and the second screen 9 to sieve left and right. The unblocked fertilizer falls into the second screen 9 from the first screen 8. The screen hole of the second screen 9 is smaller than that of the first screen 8. Smaller particles in the second screen 9 fall into the compound fertilizer tank 1. The vibration of left and right swinging can better sieve the fertilizer, ensure complete screening of the fertilizer, and effectively sieve a large amount of fertilizer at one time.

[0029] A fertilizer screening machine, such as Figure 1 、 Figure 3 and Figure 4As shown, a disintegration structure is installed inside the first screen 8. The disintegration structure includes a lead screw 13 and clamping plates 12. Several clamping plates 12 are provided on the outer wall of the lead screw 13. One end of each clamping plate 12 is threadedly connected to the lead screw 13. The disintegration structure also includes stabilizing bars 15 and displacement grooves 16. There are two sets of disintegration structures. A displacement groove 16 is opened on each side of the inner wall of the first screen 8. The side of the clamping plate 12 of each set of disintegration structures near the displacement groove 16 is fixedly connected to one side of a stabilizing bar 15. Each set of stabilizing bars 15 is slidably connected to the corresponding displacement groove 16. The disintegration structure also includes a second servo motor 14. The two ends of the lead screw 13 are rotatably connected to the other two sides of the inner wall of the first screen 8. The second servo motor 14 is fixedly installed on one side of the outer wall of the first screen 8 by a bracket. The rotating shaft of the second servo motor 14 passes through one side of the first screen 8 and is fixedly connected to one end of the lead screw 13. The rotating shaft of the second servo motor 14 is rotatably connected to the first screen 8. The clamping plates 12 of the two sets of disintegration structures are staggered.

[0030] Turn on the power to the two second servo motors 14. One of the two second servo motors 14 rotates clockwise and the other rotates counterclockwise, driving the two lead screws 13 to rotate accordingly. All the clamping plates 12 move, and the two lead screws 13 drive their respective clamping plates 12 to move closer to each other. The two sets of clamping plates 12 break up the clumps of fertilizer. The broken-up fertilizer is then screened. No manual processing is required, saving manpower and improving efficiency.

[0031] The working principle of this utility model is as follows: The fertilizer to be screened is poured into the first screen 8. The power of the first servo motor 4 is turned on, and the first servo motor 4 drives the eccentric wheel 5 to rotate. The end of the eccentric wheel 5 slides in the sliding groove 11. The moving block 7 swings, causing the two rocking rods 6 to sway left and right. The two rocking rods 6 drive the first screen 8 and the second screen 9 to sieve left and right. Unagglomerated fertilizer falls from the first screen 8 into the second screen 9. The screen holes of the second screen 9 are smaller than those of the first screen 8. Smaller particles in the second screen 9 fall into the compound fertilizer tank 1 and are sieved by the left and right sides. The right-swinging vibration can better sieve the fertilizer, ensuring thorough sieving. It can also effectively sieve large quantities at once. When the power is turned on to the two second servo motors 14, one rotates clockwise and the other counterclockwise, driving the two lead screws 13 to rotate accordingly. All the clamping plates 12 move, and the two lead screws 13 drive their respective clamping plates 12 to move closer to each other. The two sets of clamping plates 12 break up the clumps of fertilizer. The broken-up fertilizer is then sieved. No manual processing is required, saving manpower and improving efficiency.
