Description

Technical Field

[0001] This utility model relates to the technical field of water-soluble fertilizer production equipment, specifically a water-soluble fertilizer pretreatment device. Background Technology

[0002] During agricultural planting, trace elements in the soil are lost to some extent and need to be replenished. Spreading fertilizer is a relatively simple and intuitive way to replenish soil fertility, especially water-soluble fertilizer. The characteristics of water-soluble fertilizer require that it can dissolve quickly and completely in water so that it can be directly absorbed by plant roots or leaves. The crushing process in the raw material pretreatment can significantly reduce the particle size and increase the surface area, thereby improving its dissolution rate and solubility in water, ensuring that fertilizer nutrients can be released quickly and effectively absorbed by crops.

[0003] The prior art patent CN219815986U discloses a raw material pretreatment device for water-soluble fertilizer production. In the technical solution of this patent, a motor is fixedly connected to the top surface of the mixing drum body, a transmission shaft is fixedly connected to the output end of the motor, a stirring ring is fixedly connected to one side of the transmission shaft, and a stirring blade is fixedly connected to the outer surface of the stirring ring, so as to stir and crush the water-soluble fertilizer raw material inside the mixing drum. However, in this method, the stirring blade is unidirectional, which cannot meet the requirement of simultaneously stirring the water-soluble fertilizer raw material in both forward and reverse directions. However, unidirectional stirring may lead to incomplete mixing of raw materials in some areas, especially when processing raw materials with wide particle size distribution and large density differences, which can easily form mixing blind zones, resulting in uneven concentration of each component in the final product, and thus poor pretreatment effect of water-soluble fertilizer. Therefore, we propose a water-soluble fertilizer pretreatment device. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a water-soluble fertilizer pretreatment device. In use, the water-soluble fertilizer raw material is fed into the treatment tank. The drive assembly is activated, causing the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first gear and the main crushing roller to rotate. The first gear drives the second gear to rotate, which in turn drives the corresponding second rotating shaft to rotate. The second rotating shaft then drives the corresponding secondary crushing roller to rotate. This process utilizes the space between the main crushing roller and the secondary crushing roller, between adjacent secondary crushing rollers, and between the secondary crushing roller and the inner wall of the treatment tank to crush the water-soluble fertilizer raw material, thereby improving the crushing efficiency. The crushing teeth on the main crushing roller and the secondary crushing roller are staggered, further enhancing the crushing effect. The crushed water-soluble fertilizer raw material falls onto a leveling assembly, which evenly feeds it into the crushing assembly, preventing it from falling vertically to the same position and thus improving the pretreatment effect. This effectively solves the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-soluble fertilizer pretreatment device, comprising a treatment tank, a crushing component, a homogenizing component, and a grinding component; A first rotating shaft is rotatably mounted on the middle of the upper surface of the processing barrel. A material leveling component is provided in the middle of the first rotating shaft. A crushing component is installed on the upper part of the first rotating shaft. The crushing component is located above the material leveling component. A crushing component is installed on the lower part of the first rotating shaft. The crushing assembly includes a first gear mounted on the upper end of a first rotating shaft. Multiple second rotating shafts are evenly mounted around the first rotating shaft on the upper surface of the processing barrel. A second gear is mounted on the upper end of each of the second rotating shafts. The first gear meshes with the multiple second gears. A slave crushing roller is mounted on the lower end of each of the second rotating shafts. A main crushing roller is mounted on the first rotating shaft. The main crushing roller and the slave crushing roller are horizontally aligned. Multiple crushing teeth are evenly mounted on the circumferential surfaces of both the main crushing roller and the slave crushing roller.

[0006] Furthermore, the material leveling assembly includes a sieve plate installed in the middle of the inner wall of the processing barrel. A slide rail is provided on the upper edge of the sieve plate. A material leveling brush is installed on the middle side of the first rotating shaft. A sliding bracket is installed at the front end of the material leveling brush, and the lower end of the sliding bracket is slidably installed in the slide rail. Multiple sieve holes are evenly distributed on the sieve plate. An annular guide plate is installed in the middle of the inner wall of the processing barrel, located above the material leveling brush and below the crushing roller. A processing port is opened in the middle of the outer wall of the processing barrel. An arc-shaped plate is rotatably installed at the processing port via a pin. The processing port is located between the annular guide plate and the sieve plate. When the crushed water-soluble fertilizer raw material falls directly into or is guided into the sieve plate by the annular guide plate, the rotation of the first rotating shaft drives the material leveling brush to rotate. The rotating material leveling brush evenly sweeps the crushed water-soluble fertilizer raw material onto the crushing assembly below, thereby improving the pretreatment effect of the water-soluble fertilizer raw material.

[0007] Furthermore, the crushing assembly includes a first bevel gear installed at the lower part of the first rotating shaft. Four third rotating shafts are evenly rotatably installed on the inner wall of the processing barrel. A second bevel gear is installed at the front end of each third rotating shaft. The first and second bevel gears are meshed together. A crushing roller is installed on each third rotating shaft. A crushing plate is also installed at the lower part of the first rotating shaft. The crushing plate is located below the crushing roller. A protective cover is rotatably installed on the first rotating shaft. The side wall of the protective cover is rotatably connected to the third rotating shaft. Both sides of the upper surface of the crushing plate are provided with a discharge port. A discharge plate is rotatably installed at the discharge port through a second pin. A locking block is installed on the outer side of the discharge plate. A locking groove is provided on the lower surface of the crushing plate corresponding to the locking block. The locking block and the locking groove are fixedly connected by bolt threads. A driving assembly is installed on the bottom surface inside the processing barrel. The driving assembly is connected to the first rotating shaft. When the first rotating shaft rotates, it drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the third rotating shaft to rotate, and the third rotating shaft to rotate the crushing roller. The rotation of the first rotating shaft also drives the crushing plate to rotate. Thus, the rotating crushing plate and the crushing roller work together to crush the water-soluble fertilizer raw material, thereby improving the pretreatment effect of the water-soluble fertilizer raw material. After pretreatment, the water-soluble fertilizer raw material is fed into the bottom of the processing tank through the feeding port after the feeding plate is opened.

[0008] Furthermore, the drive assembly includes a motor bracket mounted on the bottom surface inside the processing tank, on which a motor is mounted. The output shaft of the motor is connected to the lower end of the first rotating shaft via a coupling, and the input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which in turn drives the first rotating shaft to rotate, thus electrically completing the rotation of the first rotating shaft.

[0009] Furthermore, a feeding channel is provided on the upper part of the outer surface of the processing barrel, which is located between two adjacent crushing rollers, and a receiving port is provided on the lower part of the outer wall of the processing barrel. Water-soluble fertilizer raw materials are added into the processing barrel through the feeding channel, and new material at the bottom of the processing barrel is collected through the receiving port.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the water-soluble fertilizer pretreatment device feeds the water-soluble fertilizer raw material into the treatment tank, and the drive component is started to drive the first rotating shaft to rotate. The rotation of the first rotating shaft drives the first gear and the main crushing roller to rotate. The first gear drives the second gear to rotate. The rotation of the second gear drives the corresponding second rotating shaft to rotate. The rotation of the second rotating shaft drives the corresponding secondary crushing roller to rotate. Thus, the water-soluble fertilizer raw material is crushed by the main crushing roller and the secondary crushing roller, by adjacent secondary crushing rollers, and by the secondary crushing roller and the inner wall of the treatment tank, thereby improving the crushing efficiency of the water-soluble fertilizer raw material. The crushing teeth on the main crushing roller and the secondary crushing roller are staggered, which can further improve the crushing effect. The crushed water-soluble fertilizer raw material falls onto the equalization component. The equalization component can evenly feed the crushed water-soluble fertilizer raw material into the crushing component to avoid the water-soluble fertilizer raw material falling vertically into the same position, thereby improving the pretreatment effect of the water-soluble fertilizer raw material.

[0013] 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.

[0014] Please see Figure 1-3 This embodiment provides a technical solution: a water-soluble fertilizer pretreatment device, including a treatment tank 1, a crushing component, a homogenizing component and a grinding component; A first rotating shaft 14 is rotatably mounted on the middle of the upper surface of the processing barrel 1. A material leveling component is provided in the middle of the first rotating shaft 14. A crushing component is installed on the upper part of the first rotating shaft 14. The crushing component is located above the material leveling component. A crushing component is installed on the lower part of the first rotating shaft 14. The crushing assembly includes a first gear 2 mounted on the upper end of a first rotating shaft 14. Multiple second rotating shafts 25 are evenly mounted around the first rotating shaft 14 on the upper surface of the processing barrel 1. A second gear 5 is mounted on the upper end of the second rotating shaft 25. The first gear 2 is meshed with the multiple second gears 5 respectively. A secondary crushing roller 7 is mounted on the lower end of the second rotating shaft 25. A main crushing roller 16 is mounted on the first rotating shaft 14. The main crushing roller 16 and the secondary crushing roller 7 are horizontally corresponding. Multiple crushing teeth 15 are evenly mounted on the circumferential surface of both the main crushing roller 16 and the circumferential surface of the secondary crushing roller 7.

[0015] In use, the water-soluble fertilizer raw material is fed into the processing tank 1. The drive assembly is started, which drives the first rotating shaft 14 to rotate. The rotation of the first rotating shaft 14 drives the first gear 2 and the main crushing roller 16 to rotate. The first gear 2 drives the second gear 5 to rotate. The rotation of the second gear 5 drives the corresponding second rotating shaft 25 to rotate. The rotation of the second rotating shaft 25 drives the corresponding secondary crushing roller 7 to rotate. Thus, the water-soluble fertilizer raw material is crushed by the main crushing roller 16 and the secondary crushing roller 7, by the adjacent secondary crushing rollers 7, and by the secondary crushing roller 7 and the inner wall of the processing tank 1, so as to improve the crushing efficiency of the water-soluble fertilizer raw material. The crushing teeth 15 on the main crushing roller 16 and the crushing teeth 15 on the secondary crushing roller 7 are staggered, which can further improve the crushing effect. The crushed water-soluble fertilizer raw material falls onto the leveling assembly. The leveling assembly can evenly feed the crushed water-soluble fertilizer raw material into the crushing assembly to avoid the water-soluble fertilizer raw material falling vertically into the same position, thereby improving the pretreatment effect of the water-soluble fertilizer raw material.

[0016] The material leveling assembly includes a sieve plate 18 installed in the middle of the inner wall of the processing tank 1. A slide rail is provided on the upper edge of the sieve plate 18. A material leveling brush 17 is installed on the middle side of the first rotating shaft 14. A sliding bracket 24 is installed at the front end of the material leveling brush 17, and the lower end of the sliding bracket 24 is slidably installed in the slide rail. Multiple sieve holes 23 are evenly distributed on the sieve plate 18. An annular guide plate 8 is installed in the middle of the inner wall of the processing tank 1, located above the material leveling brush 17 and below the crushing roller 7. A processing port is opened in the middle of the outer wall of the processing tank 1. An arc-shaped plate 3 is rotatably installed at the processing port via a pin. The processing port is located between the annular guide plate 8 and the sieve plate 18. When the crushed water-soluble fertilizer raw material falls directly into or is guided into the sieve plate 18 through the annular guide plate 8, the rotation of the first rotating shaft 14 drives the material leveling brush 17 to rotate. The rotation of the material leveling brush 17 evenly sweeps the crushed water-soluble fertilizer raw material onto the crushing assembly below, thereby improving the pretreatment effect of the water-soluble fertilizer raw material.

[0017] The crushing assembly includes a first bevel gear 19 installed at the lower part of the first rotating shaft 14. Four third rotating shafts are evenly rotatably installed on the inner wall of the processing barrel 1. A second bevel gear 20 is installed at the front end of the third rotating shaft. The first bevel gear 19 and the second bevel gear 20 are meshed and connected. A crushing roller 10 is installed on the third rotating shaft. A crushing plate 21 is also installed at the lower part of the first rotating shaft 14. The crushing plate 21 is located below the crushing roller 10. A protective cover 22 is rotatably installed on the first rotating shaft 14. The side wall of the protective cover 22 is rotatably connected to the third rotating shaft. Both sides of the upper surface of the crushing plate 21 are provided with a discharge port. A discharge plate 9 is rotatably installed at the discharge port through a second pin. A locking block 11 is installed on the outer side of the discharge plate 9. A locking groove is provided on the lower surface of the crushing plate 21 corresponding to the locking block 11. The locking block 11 and the locking groove are fixedly connected by bolt threads. A drive assembly is installed on the bottom surface inside the processing barrel 1. The drive assembly is connected to the first rotating shaft 14. When the first rotating shaft 14 rotates, it drives the first bevel gear 19 to rotate. The first bevel gear 19 rotates, which in turn drives the second bevel gear 20 to rotate. The second bevel gear 20 rotates, which in turn drives the third rotating shaft to rotate. The third rotating shaft rotates, which in turn drives the rolling roller 10 to rotate. The rotation of the first rotating shaft 14 also drives the rolling plate 21 to rotate. Thus, the rotating rolling plate 21 and the rolling roller 10 work together to roll the water-soluble fertilizer raw material, thereby improving the pretreatment effect of the water-soluble fertilizer raw material. After pretreatment, the water-soluble fertilizer raw material is fed into the bottom of the processing tank 1 through the feeding port after the feeding plate 9 is opened.

[0018] The drive assembly includes a motor bracket 12 mounted on the bottom surface inside the processing tank 1. A motor 13 is mounted on the motor bracket 12. The output shaft of the motor 13 is connected to the lower end of the first rotating shaft 14 via a coupling. The input end of the motor 13 is electrically connected to the output end of an external controller. The motor 13 is controlled by the external controller to operate, and the operation of the motor 13 drives the first rotating shaft 14 to rotate, thereby completing the rotation of the first rotating shaft 14 electrically.

[0019] A feeding channel 4 is provided on the upper part of the outer surface of the processing barrel 1. The feeding channel 4 is located between two adjacent crushing rollers 7, and a receiving port 6 is provided on the lower part of the outer wall of the processing barrel 1. Water-soluble fertilizer raw materials are added into the processing barrel 1 through the feeding channel 4, and the new material at the bottom of the processing barrel 1 is collected through the receiving port 6.

[0020] The working principle of the water-soluble fertilizer pretreatment device provided by this utility model is as follows: In use, the water-soluble fertilizer raw material is fed into the treatment tank 1. The drive component is started to drive the first rotating shaft 14 to rotate. The rotation of the first rotating shaft 14 drives the first gear 2 and the main crushing roller 16 to rotate. The first gear 2 drives the second gear 5 to rotate. The rotation of the second gear 5 drives the corresponding second rotating shaft 25 to rotate. The rotation of the second rotating shaft 25 drives the corresponding secondary crushing roller 7 to rotate. Thus, the water-soluble fertilizer raw material is crushed by the main crushing roller 16 and the secondary crushing roller 7, between adjacent secondary crushing rollers 7, and between the secondary crushing roller 7 and the inner wall of the treatment tank 1, so as to improve the crushing efficiency of the water-soluble fertilizer raw material. The crushing teeth 15 on the main crushing roller 16 and the crushing teeth 15 on the secondary crushing roller 7 are staggered, which can improve the crushing effect. The crushed water-soluble fertilizer raw material falls onto the uniform feeding component. The uniform feeding component can evenly feed the crushed water-soluble fertilizer raw material into the crushing component to avoid the water-soluble fertilizer raw material falling vertically into the same position, thereby improving the pretreatment effect of the water-soluble fertilizer raw material. When the pulverized water-soluble fertilizer raw material falls directly into or is guided into the screen plate 18 by the annular guide plate 8, the rotation of the first rotating shaft 14 drives the uniform brush 17 to rotate. The uniform brush 17 evenly sweeps the pulverized water-soluble fertilizer raw material onto the crushing component below to improve the pretreatment effect of the water-soluble fertilizer raw material. When the first rotating shaft 14 rotates, it drives the first bevel gear 19 to rotate, which in turn drives the second bevel gear 20 to rotate, which in turn drives the third rotating shaft to rotate, which in turn drives the crushing roller 10 to rotate. The rotation of the first rotating shaft 14 also drives the crushing plate 21 to rotate, so that the rotating crushing plate 21 and the crushing roller 10 work together to crush the water-soluble fertilizer raw material to improve the pretreatment effect of the water-soluble fertilizer raw material. After pretreatment, the water-soluble fertilizer raw material is fed into the bottom of the processing tank 1 through the discharge port by opening the discharge plate 9. The motor 13 is controlled by an external controller to work, and the motor 13 drives the first rotating shaft 14 to rotate, thus completing the rotation of the first rotating shaft 14 electrically. Water-soluble fertilizer raw materials are added into the treatment tank 1 through the feeding channel 4, and the new material at the bottom of the treatment tank 1 is collected through the receiving port 6.

[0021] It is worth noting that in this embodiment, the core chip of the external controller is an STC microcontroller, specifically the STC15W204S, while the motor 13 can be freely configured according to the actual application scenario.
