[0032] 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.
[0033] Reference Figure 1 - Figure 5An embodiment of this utility model provides an organic fertilizer granulator, comprising a base 4, a material cylinder 5 fixedly connected to the top of the base 4, a baffle 10 fixedly connected inside the material cylinder 5, a hydraulic cylinder 11 fixedly connected to the inner wall of the material cylinder 5, the output end of the hydraulic cylinder 11 passing through the baffle 10 and fixedly connected to an extrusion plate 9, an extension shell 3 fixedly connected to the outer side of the material cylinder 5, a perforated mesh 8 slidably connected inside the material cylinder 5, a fixing mechanism provided inside the extension shell 3, a motor 7 fixedly connected to the inner wall of the material cylinder 5, a rotating shaft 23 fixedly connected to the output end of the motor 7, multiple connecting shafts 22 fixedly connected to the outer side of the rotating shaft 23, an anti-sticking mechanism provided at the end of the connecting shaft 22 away from the rotating shaft 23, and multiple scrapers 19 fixedly connected to the outer side of the rotating shaft 23.
[0034] The fixing mechanism includes an outer shell 15, which is fixedly connected inside the extension shell 3. An inner shell 13 is fixedly connected inside the outer shell 15. A pin 16 is slidably connected inside the inner shell 13. A spring 17 is sleeved on the outside of the pin 16. A temporary locking component is provided on the outside of the pin 16. An extrusion plate 9 is slidably connected inside the material cylinder 5. A feed hopper 6 is fixedly connected to the top of the material cylinder 5. A discharge hopper 2 is fixedly connected to the bottom of the material cylinder 5. A perforated screen 8 is slidably connected inside the extension shell 3. The pin 16 is inserted into the perforated screen 8.
[0035] The base 4 serves as the supporting foundation for the entire equipment, providing a stable load-bearing platform. The material cylinder 5 is the core part of the machine, responsible for containing and processing organic fertilizer. A feed hopper 6 is fixedly connected to its top, and a discharge hopper 2 is fixedly connected to its bottom for feeding and discharging. A baffle 10 is installed inside the material cylinder 5 to protect the hydraulic cylinder 11 and prevent organic fertilizer from interfering with its operation. The hydraulic cylinder 11 is installed on the inner wall of the material cylinder 5 and drives the movement of the extrusion plate 9 to control the extrusion and granulation of the material. The extrusion plate 9 is connected to the hydraulic cylinder 11 and slides inside the material cylinder 5 as it is pushed by the hydraulic cylinder 11, extruding the material and squeezing it out through the perforated mesh 8. The extension shell 3 hydraulically supports the perforated mesh 8, ensuring that different mesh sizes can be replaced to control the size of the organic fertilizer granules. The fixing mechanism locks the perforated mesh 8 to prevent displacement during operation and facilitates replacement of the perforated mesh 8. The outer shell 15 supports the various internal parts, ensuring the proper functioning of the fixing mechanism. The pin 16 is inserted into the perforated mesh 8 to fix the mesh 8. The spring 17 prevents the pin 16 from moving when no external force is applied. The inner shell 13 provides a stable sliding track for the pin 16. The temporary locking component temporarily locks the pin 16 after it is pulled out, eliminating the need to pull the pin 16 continuously and facilitating the replacement of the perforated mesh 8.
[0036] Motor 7 drives the rotating shaft 23 to rotate, thereby causing the connecting shaft 22 and scraper 19 on the rotating shaft 23 to rotate. The scraper 19 is used to cut the extruded organic fertilizer strips into individual organic fertilizer pellets after the organic fertilizer is extruded from the perforated mesh 8 by the extrusion plate 9. The connecting shaft 22 is used to transmit the rotational force of the rotating shaft 23 to the anti-sticking mechanism, which is used to prevent the granular organic fertilizer from sticking to the inner wall of the feed cylinder 5.
[0037] Reference Figure 4 and Figure 5 The anti-adhesion mechanism includes a long shell 20, which is fixedly connected to the end of the connecting shaft 22 away from the rotating shaft 23. Multiple springs 24 are provided inside the long shell 20. A limiting plate 1 is slidably connected inside the long shell 20. A scraper 21 is fixedly connected to the outside of the limiting plate 1. The scraper 19 abuts against the surface of the perforated mesh 8. The scraper 21 abuts against the inner wall of the material cylinder 5. The scraper 21 passes through the long shell 20 and is slidably connected inside the long shell 20. One end of the spring 24 is fixedly connected to the side of the limiting plate 1 away from the scraper 21, and the other end of the spring 24 abuts against the inner wall of the long shell 20.
[0038] The elongated shell 20 serves to support the various internal components, ensuring the proper functioning of the anti-sticking mechanism. Spring 24 keeps the scraper 21 in constant contact with the inner wall of the barrel 5, preventing organic fertilizer granules from sticking to the inner wall. The limiting plate 1 prevents the scraper 21 from sliding out of the elongated shell 20.
[0039] Reference Figure 2 and Figure 3 The temporary locking assembly includes a pad 18, which is fixedly connected to the outside of the pin 16. An L-shaped rod 12 is fixedly connected to the outside of the pad 18. An L-shaped groove 14 is provided on the outside of the inner shell 13. The L-shaped rod 12 is slidably connected inside the L-shaped groove 14. One end of a spring 17 is fixedly connected to one side of the pad 18, and the other end of the spring 17 abuts against the inner wall of the inner shell 13.
[0040] The pad 18 is used to fix the L-shaped rod 12 and also to transmit the elastic force of the spring 17 to the pin 16, ensuring that the pin 16 can be stably inserted into the mesh 8. The L-shaped rod 12 cooperates with the L-shaped groove 14. After the pin 16 is pulled out of the mesh 8, by rotating the pin 16, the L-shaped rod 12 can be locked in the L-shaped groove 14, so that the pin 16 is temporarily locked and does not need to be pulled all the time.
[0041] Working principle: When using this device, firstly, an appropriate amount of raw material is fed into the material cylinder 5 through the feed hopper 6. Then, the hydraulic cylinder 11 is activated, driving the extrusion plate 9 to slide back and forth in the material cylinder 5, applying pressure and pushing the raw material to be extruded through the perforated mesh 8. At the same time, the motor 7 is activated, driving the rotating shaft 23 to rotate, which in turn drives the connecting shaft 22 and the scraper 19 mounted on it to rotate synchronously.
[0042] After the raw material is squeezed through the perforated mesh 8, it is rapidly cut into uniform small particles under the continuous rotation of the scraper 19. Simultaneously, the scraper 21 continuously adheres to the inner wall surface of the cylinder 5, effectively scraping away the organic fertilizer particles adhering to the inner wall, preventing material accumulation, and ensuring a clean and smooth internal flow of the equipment. Finally, the granulated organic fertilizer particles are discharged through the discharge hopper 2, achieving continuous operation.
[0043] When adjusting particle size, simply replace the mesh 8 with one of different aperture sizes. The replacement steps are as follows: First, pull the pin 16 to remove it from the mesh 8; then rotate the pin 16 to engage the L-shaped rod 12 into the L-shaped groove 14. At this point, the pin 16 is temporarily locked, eliminating the need for continuous manual pulling and making the operation more convenient. Next, remove the mesh 8 from the feed cylinder 5 using the handle at the top and replace it with a new mesh 8; then rotate the pin 16 in the opposite direction to disengage the L-shaped rod 12 from the L-shaped groove 14 and restore its sliding state. Finally, release the pin 16. Under the action of the spring 17, the pin 16 will automatically reset and insert into the new mesh 8, completing the replacement operation.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
