[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-5 As shown, this utility model provides a granulated fertilizer finished product screening and powder recovery device, including a granulation equipment body 1, which serves as the source of granulated fertilizer production. A screening component 2 is provided on one side of the granulation equipment body 1, which can screen the granulated fertilizer produced by the granulation equipment body 1 and separate the powder. A collection box 4 is fixedly installed on one side of the granulation equipment body 1, which is used to collect the screened powder. A discharge pipe 6 is connected to the lower surface of the collection box 4, facilitating the discharge of powder. A vibrator body 5 is provided on the lower surface of the collection box 4. Here, the vibrator body 5 is an Ande brand ZDQ type electromagnetic bin vibrator. The vibrator body 5 is installed on the lower surface of the collection box 4, allowing the powder in the collection box 4 to be discharged smoothly and avoiding blockage. A conveying component 3 is provided between the discharge pipe 6 and the granulation equipment body 1, which transports the powder discharged from the collection box 4 back to the granulation equipment body 1, realizing the recycling of powder, improving raw material utilization, and reducing production costs.

[0016] The screening assembly 2 includes a housing 21, which is fixedly installed on one side of the granulation equipment body 1. A DC motor 203 is fixedly connected to one side of the housing 21, and a first base 202 for use with the DC motor 203 is fixedly installed on one side of the housing 21. The DC motor 203 is fixedly installed on the upper surface of the first base 202, which provides a stable mounting position for the DC motor 203, ensuring the stability of the DC motor 203 during operation. The output end of the DC motor 203 passes through one side of the housing 21 and is fixedly connected to a disc 201. The output end of the DC motor 203 and the disc... The fixed connection 201 allows the rotational power of the DC motor 203 to be directly transmitted to the disk 201. The rotation of the disk 201 drives the movement of subsequent components. A lever 22 is fixedly connected to an eccentric part of one side of the disk 201. When the disk 201 rotates, the lever 22 moves in a circular motion with the disk 201, generating a reciprocating pushing action and providing periodic driving force to the moving frame 23. The moving frame 23 is slidably sleeved on the outer surface of the lever 22. This sliding sleeve connection allows the lever 22 to drive the moving frame 23 to reciprocate linearly during its circular motion. Guide rods 24 are symmetrically fixedly connected to both sides of the moving frame 23, and guide sleeves 25 are symmetrically fixedly connected to the inner wall of the housing 21. Correspondingly, the guide rods 24 and guide sleeves 25 are slidably connected. This slidable connection structure provides guidance for the reciprocating motion of the moving frame 23, ensuring that the moving frame 23 does not deviate or shake during movement, making the movement of the moving frame 23 more stable. A connecting rod 29 is fixedly sleeved on the outer surface of the guide rod 24. A limiting groove 27 for use with the connecting rod 29 is opened on one side of the housing 21. One end of the connecting rod 29 passes through the limiting groove 27. The connecting rod 29 is slidably connected to the limiting groove 27, which limits the movement of the connecting rod 29 and further restricts the movement trajectory of the moving frame 23. The upper surface of the connecting rod 29 is magnetically attached to the locking block 28, and the screen frame 26 is fixedly connected to one side of the locking block 28. The connecting rod 29 transmits the movement of the moving frame 23 to the screen frame 26, so that the screen frame 26 can perform screening work with the movement of the moving frame 23. The magnetic locking method connects the connecting rod 29 and the locking block 28, making the installation and disassembly of the screen frame 26 more convenient and quick. Operators can easily and quickly remove the granular fertilizer, effectively shortening the production cycle.

[0017] The conveying assembly 3 includes a first conveying pipe 301, which is connected to a discharge pipe 6. The first conveying pipe 301 and the discharge pipe 6 provide a conveying channel for the powder discharged from the collection box 4. A positioning seat 34, which works in conjunction with the first conveying pipe 301, is fixedly installed on the lower surface of the collection box 4. The positioning seat 34 is fixedly sleeved on the outer surface of the first conveying pipe 301, providing stable installation support for the first conveying pipe 301 and ensuring that the connection position between the first conveying pipe 301 and the collection box 4 is fixed. A fixed installation is also provided on one side of the first conveying pipe 301. A first servo motor 33 is provided, and its output end is fixedly connected to a first auger conveyor 31 through one side of the first conveying pipe 301. The first servo motor 33 drives the first auger conveyor 31 to rotate, thus conveying the powder discharged from the discharge pipe 6 into the first conveying pipe 301. A connecting pipe 39 is connected to one side of the first conveying pipe 301, and a second conveying pipe 35 is connected to one side of the connecting pipe 39. The connecting pipe 39 connects the first conveying pipe 301 and the second conveying pipe 35, allowing the powder to smoothly enter the second conveying pipe 35 from the first conveying pipe 301, achieving multi-stage conveying of the powder. A second servo motor 37 is fixedly connected to one side of the conveying pipe 35. A first support 32 and a second support 38 are fixedly installed on one side of the first conveying pipe 301 and the second conveying pipe 35, respectively. The first servo motor 33 and the second servo motor 37 are fixedly installed on the upper surfaces of the first support 32 and the second support 38, respectively. The first support 32 and the second support 38 provide a stable mounting base for the first servo motor 33 and the second servo motor 37, respectively. The output end of the second servo motor 37 passes through one side of the second conveying pipe 35 and is fixedly connected to a second auger conveyor 36. The second servo motor 37 drives the second auger conveyor 36. The rotation further conveys the powder within the second conveying pipe 35, delivering it to the discharge pipe 302. The second auger conveyor 36 cooperates with the first auger conveyor 31 to achieve relay conveying of the powder, stably transporting it from the collection box 4 to the granulation equipment body 1, completing the powder recycling process and improving the efficiency and effectiveness of powder recycling. The discharge pipe 302 is connected to one side of the second conveying pipe 35, serving as the discharge end of the conveying component 3. It discharges the powder conveyed by the first conveying pipe 301 and the second conveying pipe 35, facilitating the transport of the powder to the granulation equipment body 1 and realizing the recycling and reuse of the powder.

[0018] Working principle: After the granulation equipment body 1 produces granulated fertilizer, the granulated fertilizer enters the screening component 2 for screening. The DC motor 203 is started, and the output end of the DC motor 203 drives the disc 201 to rotate. The lever 22 at the eccentric position on one side of the disc 201 then makes a circular motion.

[0019] The movable frame 23, which is slidably sleeved on the outer surface of the lever 22, reciprocates linearly under the action of the lever 22. The guide rods 24 on both sides of the movable frame 23 are slidably connected to the guide sleeves 25 on the inner wall of the housing 21 to ensure the stability and accuracy of the movement of the movable frame 23.

[0020] The connecting rod 29, which is fixedly sleeved on the outer surface of the guide rod 24, has one end passing through the limiting groove 27 on one side of the housing 21 and slidingly connected to the limiting groove 27. It transmits the movement of the moving frame 23 to the screen frame 26. The screen frame 26 is fixed by the card block 28 on the upper surface of the connecting rod 29 through magnetic attraction. As the moving frame 23 moves, it screens the granular fertilizer and filters out the powder. The screened powder falls into the collection box 4. The vibrator body 5 on the lower surface of the collection box 4 works, which makes the powder pass smoothly through the discharge pipe 6 and then enter the conveying assembly 3.

[0021] First, the material enters the first conveying pipe 301, which is connected to the discharge pipe 6. The positioning seat 34, which is fixedly installed on the lower surface of the collection box 4, is fixedly sleeved on the outer surface of the first conveying pipe 301 to provide stable support for the first conveying pipe 301 and ensure the stability and smoothness of the powder conveying.

[0022] The first servo motor 33 is started, which drives the first auger conveyor 31 to rotate, conveying the powder material into the first conveying pipe 301. The first conveying pipe 301 is connected to the second conveying pipe 35 through the connecting pipe 39, and the powder material enters the second conveying pipe 35 from the first conveying pipe 301.

[0023] The second servo motor 37 is started, which drives the second auger conveyor 36 to rotate and continue to convey the powder. Finally, the powder is conveyed back to the granulation equipment body 1 through the discharge pipe 302 connected to one side of the second conveying pipe 35, thus completing the recycling of the powder.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
