Description

Technical Field

[0001] This utility model relates to the technical field of stirring tooth granulation equipment, specifically to a stirring tooth granulator with a built-in crushing mechanism. Background Technology

[0002] A toothed granulator, also known as a toothed pellet mill or toothed granulator, is a device used to process powdery or fine granular materials into spherical or near-spherical particles. It is widely used in industries such as fertilizer, feed, chemical, and environmental protection.

[0003] Chinese utility model CN218689222U proposes a "rotary drum-type stirring tooth granulator." This device uses a drive rod that runs through the entire outer cylinder. Most of the sticky material on the inner wall of the outer cylinder is cleaned away by rotating blades. The remaining material in the gaps between the blades and the cylinder is completely cleaned by the elastic rubber lining inside the cylinder, along with the cylinder's self-cleaning vents. This saves manpower and effectively solves the problem of sticky material adhering to the cylinder walls. However, in actual production, especially in the manufacturing process of organic fertilizers or bio-fertilizers, this presents challenges. In this process, raw materials often include biomass materials such as livestock and poultry manure, well-rotted compost, straw powder, and mushroom residue. If these materials are not sufficiently crushed during the pretreatment stage, large lumps, hard agglomerates, or fibrous clumps are easily left behind, such as incompletely crushed manure blocks and straw bundles. When these large-sized impurities enter the stirring tooth granulator, they not only have difficulty participating in the normal pelletizing process, but also interfere with the uniform flow and rolling of the material, block the gap between the stirring teeth, cause localized material jamming or equipment overload, and even cause the surface of the granules to be rough and the strength insufficient, affecting the quality of the final product. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a stirring tooth granulator with a built-in crushing mechanism. This solves the technical problem in the existing stirring tooth granulator that, due to the lack of a dedicated crushing device, large lumps, hard agglomerates, or fibrous tangles remain in the raw materials and are difficult to participate in normal pelletizing after entering the machine body, thus affecting the working efficiency of the granulation equipment.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a stirring tooth granulator with a built-in crushing mechanism, comprising:

[0007] The machine body has a feeding window and a discharging window on its surface;

[0008] The crushing mechanism includes a processing box, a diversion plate, and a crushing end. The processing box is disposed on the machine body and communicates with the feed window. The processing box is provided with a diversion plate, and the lower end of the diversion plate is provided with a crushing end.

[0009] A stirring tooth mechanism includes a drive end and a stirring tooth end. The drive end is located outside the machine body, and its output end extends into the machine body and is connected to the stirring tooth end. The stirring tooth end is used to process materials.

[0010] An elastic support member includes a plurality of support frames, wherein the plurality of support frames are disposed at the lower end of the body, and an elastic element is disposed within the support frames.

[0011] In some embodiments, the upper end of the processing box is provided with an opening, and a diverter plate with a central protrusion is provided below the opening.

[0012] In some embodiments, the crushing end includes a crushing roller, a shaft, and a first motor. The crushing roller is axially disposed inside the processing box, and a shaft is installed inside it. One end of the shaft passes through the processing box and is connected to the output end of the first motor.

[0013] In some embodiments, a screening end is provided below the crushing roller. The screening end includes a limiting plate with an arc-shaped groove. The crushing roller is disposed in the arc-shaped groove. Both sides of the limiting plate are connected to the inner wall of the processing box. A guide plate is provided at its upper end. The guide plate and the limiting plate are hollow. A first screen is installed on the guide plate. A second screen is provided on the limiting plate and at the lower end of the crushing roller.

[0014] In some embodiments, the limiting plate is further provided with auxiliary teeth that cooperate with the crushing roller.

[0015] In some embodiments, the drive end includes a second motor, a first pulley, a second pulley, and a transmission belt; the second motor is disposed outside the machine body, and the output end of the second motor is connected to the first pulley, the second pulley is disposed above the first pulley, a transmission belt is disposed between the first pulley and the second pulley, and a stirring tooth end disposed inside the machine body is connected to the second pulley.

[0016] In some embodiments, the stirring tooth end includes a stirring shaft and a plurality of stirring teeth. The stirring shaft is axially disposed within the machine body, with one end passing through the machine body and connected to the second pulley. The plurality of stirring teeth are circumferentially disposed on the stirring shaft and arranged along the length direction of the stirring shaft.

[0017] In some embodiments, reinforcing bars are installed at an angle on both sides of the support frame.

[0018] In some embodiments, the elastic element includes a housing, a plurality of spring dampers, and a buffer plate. The housing is mounted on the support frame, and the spring dampers are disposed inside the housing and extend to the outside of the housing. The upper end of the spring damper is connected to the buffer plate, and the buffer plate abuts against the lower end of the support frame.

[0019] In some embodiments, the number of support frames is at least three.

[0020] Compared with existing technologies, this utility model provides a stirring tooth granulator with a built-in crushing mechanism. By integrating the crushing mechanism into the machine body, including a processing box, a diverter plate, and a crushing end, the material undergoes preliminary crushing treatment in the processing box, which is connected to the feed window, before entering the granulation chamber. The diverter plate evenly guides and disperses the incoming material, preventing it from concentrating and impacting the crushing end. The crushing end, located at its lower end, effectively breaks up large clumps or agglomerates, such as insufficiently crushed manure lumps or straw clumps. This pre-crushing function significantly reduces the possibility of large particles entering the stirring tooth area, thus preventing them from interfering with the normal pelletizing process and improving particle uniformity and pelletizing rate. The feed window is directly connected to the processing box, allowing the crushed material to fall smoothly into the machine body and be crushed by the stirring tooth mechanism. Subsequent granulation processing is carried out; the finished granules are discharged through the discharge window. This layout makes the material flow path clear and continuous, avoiding the risk of transfer interruption or blockage caused by external crushing equipment in traditional processes. It is conducive to achieving efficient, stable and continuous production. The drive end of the stirring tooth mechanism is set outside the machine body, and only the output end extends into the machine body to connect to the stirring tooth end. On the one hand, it avoids the direct exposure of electrical components such as the drive motor to the high humidity and high dust granulation environment, reducing the failure rate. On the other hand, it facilitates daily inspection and maintenance. The drive system can be operated without disassembling the entire machine body, which improves the availability and operational reliability of the equipment. The elastic support component set at the bottom of the machine body can absorb and buffer the vibration and impact generated by the high-speed operation of the stirring tooth mechanism, improve the overall stability of the equipment, and extend its service life.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a stirring tooth granulator with a built-in crushing mechanism in one embodiment of the present invention. A stirring tooth granulator with a built-in crushing mechanism includes a machine body 1, on the surface of which a feeding window 11 and a discharging window 12 are respectively opened.

[0029] The crushing mechanism 2 includes a processing box 21, a diversion plate 22 and a crushing end 23. The processing box 21 is set on the machine body 1 and is connected to the feed window 11. The processing box 21 is provided with a diversion plate 22, and the lower end of the diversion plate 22 is provided with the crushing end 23.

[0030] The stirring tooth mechanism 3 includes a drive end 31 and a stirring tooth end 32. The drive end 31 is located outside the machine body 1, and its output end extends into the machine body 1 and is connected to the stirring tooth end 32. The stirring tooth end 32 is used to process materials.

[0031] The elastic support 4 includes a plurality of support frames 41, which are disposed at the lower end of the body 1, and elastic elements 42 are disposed inside the support frames 41.

[0032] In this embodiment, by setting a crushing mechanism 2 on the machine body 1, the material undergoes preliminary crushing treatment via a processing box 21 connected to the feed window 11 before entering the granulation chamber of the machine body 1. The diversion plate 22 can uniformly guide and disperse the incoming material, preventing the material from concentrating and impacting the crushing end 23. The crushing end 23 at its lower end can effectively break up large lumps or agglomerates, such as insufficiently crushed manure lumps or straw clumps. This pre-crushing function significantly reduces the possibility of large particles entering the stirring tooth area, thereby avoiding interference with the normal pelletizing process, improving particle uniformity and pelletizing rate. The feed window 11 is directly connected to the processing box 21, and the crushed material can fall smoothly into the machine body 1 for subsequent granulation processing by the stirring tooth mechanism 3. The finished pellets are then discharged via the discharge end. The material is discharged through window 12. This layout makes the material flow path clear and continuous, avoiding the risk of transfer interruption or blockage caused by external crushing equipment in traditional processes. It is conducive to achieving efficient and stable continuous production. The drive end 31 of the stirring tooth mechanism 3 is set outside the machine body 1, and only the output end extends into the machine body 1 to connect to the stirring tooth end 32. On the one hand, it avoids the direct exposure of electrical components such as the drive motor to the high humidity and high dust granulation environment, reducing the failure rate. On the other hand, it facilitates daily inspection and maintenance. The drive system can be operated without disassembling the entire machine body 1, which improves the availability and operational reliability of the equipment. The elastic support 4 set at the bottom of the machine body 1 can absorb and buffer the vibration and impact generated by the high-speed operation of the stirring tooth mechanism 3, improve the overall stability of the equipment, and extend its service life.

[0033] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 5 To improve material guiding efficiency and facilitate better crushing of agglomerated materials, the upper end of the processing box 21 is provided with an opening 211. Below the opening 211, a centrally protruding diversion plate 22 is provided. The crushing end 23 includes a crushing roller 231, a shaft 232, and a first motor 233. The crushing roller 231 is axially arranged inside the processing box 21, and the shaft 232 is installed inside it. One end of the shaft 232 passes through the processing box 21 and is connected to the output end of the first motor 233. A screening end 24 is also provided below the crushing roller 231. The screening end 24 includes a limiting plate 241, which has an arc-shaped groove and a crushing roller 231 is installed inside the arc-shaped groove. The two sides of the limiting plate 241 are connected to the inner wall of the processing box 21. A guide plate 2411 is installed at its upper end. The guide plate 2411 and the limiting plate 241 are hollow. A first screen 242 is installed on the guide plate 2411. A second screen 243 is installed on the limiting plate 241 and below the crushing roller 231. The limiting plate 241 is also provided with auxiliary teeth 244 that cooperate with the crushing roller 231.

[0034] In this embodiment, the upper end of the processing box 21 is provided with an opening 211 for feeding, and a diversion plate 22 with a central protrusion is provided below it. This structure can symmetrically guide the incoming material along both sides of the diversion plate 22, avoiding concentrated material impact on local areas of the crushing roller 231. This uniform material distribution method not only reduces the instantaneous load on the crushing roller 231, preventing jamming or overload, but also allows the material to contact the crushing roller 231 more fully, significantly improving crushing efficiency and fineness consistency. The limiting plate 241 is provided with an arc-shaped groove that matches the contour of the crushing roller 231, and auxiliary teeth 244 are provided on the inner side of the groove, forming a crushing area that cooperates with the surface of the crushing roller 231. When the material passes through this gap, it is not only crushed by the crushing roller 231, but also further torn and dispersed by the auxiliary teeth 244. It has excellent crushing ability, especially for fibrous or elastic agglomerates, such as uncomposted straw, effectively preventing To prevent slippage or roller entanglement, the first screen 242, located on the guide plate 2411, intercepts larger particles, while smaller particles pass directly through and enter the machine body 1. Larger particles then flow back along the guide plate 2411 to the crushing area for further crushing. The second screen 243, located on the limiting plate 241 directly below the crushing roller 231, performs final particle size screening on the initially crushed material. Only fine materials meeting granulation requirements are allowed to pass through and enter the lower stirring chamber, ensuring that the material entering the stirring mechanism 3 has a uniform particle size and is free of large impurities. This fundamentally avoids interference from large particles in the pelletizing process. The hollow structure between the guide plate 2411 and the limiting plate 241 not only provides a smooth falling channel for the undersize material but also serves as an airflow buffer, assisting in the discharge of dust or water vapor during equipment operation, reducing the risk of screen blockage, and maintaining long-term stable screening efficiency.

[0035] In one embodiment, please refer to Figure 1 and Figure 4 To improve the granulation efficiency of the equipment, the drive end 31 includes a second motor 311, a first pulley 312, a second pulley 313, and a transmission belt 314. The second motor 311 is located outside the machine body 1, and the output end of the second motor 311 is connected to the first pulley 312. The second pulley 313 is located above the first pulley 312. The transmission belt 314 is located between the first pulley 312 and the second pulley 313. The stirring tooth end 32 located inside the machine body 1 is connected to the second pulley 313. The stirring tooth end 32 includes a stirring shaft 321 and a plurality of stirring teeth 322. The stirring shaft 321 is axially located inside the machine body 1, with one end penetrating through the machine body 1 and connected to the second pulley 313. The plurality of stirring teeth 322 are circumferentially arranged on the stirring shaft 321 and arranged along the length direction of the stirring shaft 321.

[0036] In this embodiment, the second motor 311 is located outside the machine body 1. Through the cooperation of the first pulley 312, the transmission belt 314, and the second pulley 313, power is transmitted to the stirring tooth end 32 inside the machine body 1. This keeps the second motor 311 away from the high humidity, high dust, and high adhesion environment inside the granulation chamber, significantly reducing the risk of electrical components becoming damp, dusty, or corroded, extending the service life of the drive system, and reducing downtime due to environmental factors. Using the transmission belt 314 as the power transmission medium has good elastic buffering characteristics compared to rigid direct connection or gear transmission. When the stirring tooth end 32 experiences impact loads due to material agglomeration, foreign object obstruction, or sudden load changes, the transmission belt 314 can absorb some of the impact energy through slight slippage or elastic deformation, preventing damage to the motor or stirring shaft 321 due to overload, thereby improving the stability and safety of the entire machine operation. The first pulley 312 is located at the output end of the second motor 311, and the second pulley 313... The pulley 313 is located above it and connected to the stirring shaft 321 that runs through the machine body 1, forming a compact vertical transmission layout. This structure not only saves lateral space, but also facilitates belt tension adjustment, replacement, or maintenance from the side or top of the equipment without disassembling the main body of the machine body 1, significantly improving maintenance convenience. One end of the stirring shaft 321 runs through the wall of the machine body 1 and is fixedly connected to the second pulley 313, ensuring direct and efficient transmission of rotational power from the external drive end 31 to the internal stirring tooth end 32, reducing energy loss in intermediate transmission links. Several stirring teeth 322 are evenly arranged circumferentially on the stirring shaft 321 and continuously arranged along the axial direction to form a three-dimensional stirring area. This structure can achieve all-round tumbling, shearing, and extrusion of materials entering the machine body 1, which not only promotes the uniform mixing of powder and moisture / binder, but also continuously promotes the agglomeration, growth, and densification of fine powder during the rolling process, significantly improving the pelleting rate, particle roundness, and strength.

[0037] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 To improve the stability of the equipment, reinforcing rods 411 are installed at an angle on both sides of the support frame 41. The elastic element 42 includes a housing 421, several spring dampers 422 and a buffer plate 423. The housing 421 is installed on the support frame 41, and the spring dampers 422 are located inside the housing 421 and extend to the outside of the housing 421. The upper end of the spring damper 422 is connected to the buffer plate 423, and the buffer plate 423 abuts against the lower end of the support frame 41. The number of support frames 41 is at least three.

[0038] In this embodiment, reinforcing rods 411 are installed obliquely on both sides of the support frame 41 to form a stable triangular mechanical structure, which effectively enhances the bending and torsional resistance of the support frame 41 during equipment operation. This prevents the support frame 41 from deforming or fatigue cracking due to periodic vibrations caused by the high-speed rotation of the stirring gear mechanism 3, thereby significantly improving the stability of the overall structure and the reliability of long-term operation. The elastic element 42 adopts a structure in which several spring dampers 422 are encapsulated in a housing 421. One end of the spring damper 422 is fixed inside the housing 421, and the other end extends to the outside of the housing 421 and is connected to the buffer plate 423. This not only protects the spring damper 422 from external dust, moisture or material corrosion and extends its service life, but also efficiently absorbs and attenuates the high-frequency vibrations and impact loads generated during equipment operation through the synergistic effect of the elastic deformation of the spring and the energy dissipation of the damper. To prevent vibration from being transmitted to the ground or foundation structure, the buffer plate 423 is set on the upper end of the spring damper 422 and directly abuts against the lower end face of the support frame 41. This allows the weight of the entire machine and the dynamic load to be evenly distributed to multiple spring dampers 422 through the buffer plate 423. This avoids the local stress concentration problem commonly found in traditional point supports or rigid connections, effectively protects the connection between the support frame 41 and the machine body 1, reduces the risk of weld cracking or bolt loosening, and improves the safety of equipment operation. The number of support frames 41 is limited to at least three, which can form a stable multi-point support plane. Three points constitute a plane, and more points further enhance redundancy stability, making the machine body 1 more evenly stressed during operation. Even if the ground is slightly uneven or the local load fluctuates, it can maintain overall balance and prevent the equipment from shaking, tilting or overturning. This is especially suitable for industrial scenarios with long-term continuous operation.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 5The technical solution of this utility model is described in detail below: Powdered or agglomerated materials to be granulated, such as insufficiently crushed livestock manure, straw clumps, compost, etc., enter the equipment through the opening 211 at the top of the processing box 21. The material first falls onto the centrally raised diversion plate 22. This diversion plate 22 has a raised top structure, allowing the incoming material to slide symmetrically along both sides, achieving uniform material distribution and preventing concentrated material impact on the lower crushing area, thus laying the foundation for subsequent efficient crushing. After diversion, the powdery raw material directly passes through the first screen 242, while large particles enter the crushing end 23 area. The first motor 233 drives the shaft 232 to rotate, driving the crushing roller 23. 1. The material rotates at high speed inside the processing box 21. Simultaneously, the arc-shaped groove on the limiting plate 241 matches the contour of the crushing roller 231. The auxiliary teeth 244 on its inner side form a narrow shearing gap with the surface of the crushing roller 231. When the material passes through this gap, it is subjected to the crushing action of the crushing roller 231 and the tearing and scraping action of the auxiliary teeth 244. It has excellent crushing effect, especially for fibrous, elastic or wet sticky agglomerates, such as straw bundles and manure lumps, and effectively prevents the material from slipping or tangling. The second screen 243 is set on the limiting plate 241 and directly below the crushing roller 231 to perform the final particle size screening of the crushed material. Only when the particle size of the material is smaller than 100 mm will the screen be screened. When the sieve aperture size is set, the fine powder material can pass through the second sieve 243 and fall into the lower body 1. The qualified fine powder material enters the granulation chamber inside the body 1 through the feed window 11. At this time, the stirring tooth mechanism 3 starts to work. The second motor 311 drives the second pulley 313 to rotate through the first pulley 312 and the transmission belt 314, transmitting power to the stirring shaft 321 that penetrates the wall of the body 1. Several stirring teeth 322 arranged circumferentially and axially continuously on the stirring shaft 321 rotate at high speed, tumbling, shearing, squeezing and throwing the material in all directions. Under the action of moisture or binder, the fine powder gradually agglomerates into nuclei and grows continuously in the rolling friction. The pelletizing process densifies the pellets, resulting in round, high-strength granules. Under the influence of gravity and the pushing action of the stirring teeth, the pellets move towards the tail of the machine body 1 and are eventually discharged continuously through the discharge window 12, completing the pelletizing process. The stability of the machine body 1 is enhanced by the support frame 41. The inclined reinforcing rods 411 on both sides of the support frame 41 enhance the structural rigidity and resist torsional vibration. The spring damper 422 inside the shell 421 abuts against the lower end of the support frame 41 through the buffer plate 423, effectively absorbing the vibration and impact generated by the high-speed operation of the stirring tooth mechanism 3. The elastic buffer and damping energy dissipation work together to significantly reduce the vibration amplitude of the whole machine, protect the basic structure, and extend the service life of the equipment.

[0040] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
