[0026] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0027] 1. A longitudinal rotating mixing mechanism is provided. Through the mutual cooperation between the components inside the longitudinal rotating mixing mechanism, the fertilizer production process of the fertilizer mixing equipment is optimized. Through the mutual cooperation between the upper hopper and the components at its bottom, the raw materials of the compound fertilizer can be added to the central mixing tower at a uniform speed and uniformly, which improves the convenience of adding the raw materials of the compound fertilizer. Through the mutual cooperation between the components between the conical grinding wheel and the grinding annular cover, the large particles of the raw materials can be evenly ground into fine particles during the raw material addition process, effectively avoiding the raw materials from being mixed unevenly due to the excessively large particles during the mixing process, thereby effectively improving the mixing effect of the compound fertilizer and the product quality of the compound fertilizer. In the process of the compound fertilizer raw materials being mixed and ascending, the alternating and disordered rotation of the disturbance blades will further disturb the ascending path of the compound fertilizer raw materials, while increasing the compound fertilizer mixing path, the retention time of the compound fertilizer raw materials in the central mixing tower is prolonged, ensuring that the compound fertilizer has sufficient time to be mixed during the ascending process, and further improving the mixing effect of the compound fertilizer.

[0028] The compound fertilizer raw materials are guided by the limiting cone net to ensure that the large-particle raw materials can fall smoothly and evenly into the grinding annular cover to ensure the normal loading process of the compound fertilizer raw materials. The discharge process of the mixed compound fertilizer is optimized by the mutual cooperation between the intercepting fan-shaped plate, the air guide mesh plate and the isolation rotating frame. The compound fertilizer can be gathered while the air flow is discharged through the air guide mesh plate, and a temporary independent cavity can be formed at the bottom of the intercepting fan-shaped plate through the rotation of the isolation rotating frame, so that the gathered compound fertilizer is no longer affected by the rising air flow and falls downward along the inner wall of the mixed discharge barrel under the action of gravity, so as to complete the mixing and separation of the compound fertilizer.

[0029] Then, through the mutual cooperation among the components among the exhaust hood, the water supply cooling box and the cooling flat box, the low-temperature circulating water is continuously introduced into the central mixing tower during the compound fertilizer proportioning and mixing process, thereby making full use of the airflow discharged from the top of the mixing discharge barrel, and recondensing and gathering the evaporated compound fertilizer raw materials gathered on the upper layer of the central mixing tower through the low-temperature component composed of the heat-conducting vertical rod and the condensation reed, and the gathered compound fertilizer raw materials are re-participated in the mixing process inside the central mixing tower by knocking the small pieces, thereby effectively avoiding the sublimated gaseous compound fertilizer raw materials being directly discharged into the atmosphere with the airflow to cause pollution, further improving the environmental protection of the compound fertilizer production process, and optimizing the smoothness of the use of the compound fertilizer production equipment.

[0030] 2. A multi-stage differential circulation discharging mechanism is set up. Through the mutual cooperation between the components inside the multi-stage differential circulation discharging mechanism, the discharging process of compound fertilizer is optimized. Through the structural design of the multi-stage interception circular plate, the compound fertilizer is effectively prevented from falling vertically too fast inside the mixed discharging barrel and raising dust to pollute the surrounding of the production equipment. While the compound fertilizer falls down layer by layer, the compound fertilizer is scraped by the discharging scraper, and the compound fertilizer is humidified by the spray ring box and the spray head. The scraping of the discharging scraper cooperates with the arc groove on the interception circular plate to preliminarily granulate the compound fertilizer, so as to prevent the compound fertilizer from being too loose and adhering to the conveyor belt to cause loss during the subsequent transportation process, thereby effectively improving the subsequent transportation process of the compound fertilizer;

[0031] At the same time, the mutual cooperation between the driving inner gear ring, the driving outer gear ring and the transmission gear enables the discharging shaft to drive the discharging scraper to rotate slowly during the rotation process, thereby effectively avoiding the discharging scraper from rotating too fast and rubbing against the intercepting circular plate for a long time and causing serious heat, thereby effectively avoiding the secondary volatilization of the compound fertilizer during the discharging process due to the excessively high ambient temperature, thereby ensuring the smooth progress of the discharging process and further optimizing the unloading process of the compound fertilizer.

[0032] In summary, through the mutual cooperation between the longitudinal rotating mixing mechanism and the multi-stage differential circulating discharging mechanism, the proportioning mixing process in the compound fertilizer production process is optimized, and the continuous rising airflow is used as the main driving force for fertilizer mixing. The particle size of the raw materials can be screened by the size of the wind force during the mixed transportation of the raw materials, thereby ensuring that the compound fertilizer is mixed more evenly and stably. In the process of mixed transportation of compound fertilizer, the temperature inside the mixing equipment is adjusted so that the sublimated fertilizer raw materials can be re-condensed and separated and re-participated in the fertilizer mixing process. The temperature and transportation method during the transportation of compound fertilizer are adjusted to prevent secondary volatilization and dusting of the compound fertilizer during transportation, thereby effectively preventing pollution to the surrounding environment during the production of compound fertilizer, and effectively improving the environmental protection performance of the compound fertilizer production process.

In addition, during the process of the compound fertilizer raw materials being mixed and ascending, the alternating and disordered rotation of the disturbance blades 522 will further disturb the ascending path of the compound fertilizer raw materials, while increasing the compound fertilizer mixing path, prolonging the retention time of the compound fertilizer raw materials in the central mixing tower 2, ensuring that the compound fertilizer has sufficient time to be mixed during the ascending process, and further improving the mixing effect of the compound fertilizer.

[0065] The compound fertilizer raw materials are guided by the limiting cone net 517 to ensure that the large-particle raw materials can fall smoothly and evenly into the grinding annular cover 515, so as to ensure the normal loading process of the compound fertilizer raw materials. The discharge process of the mixed compound fertilizer is optimized by the mutual cooperation between the intercepting fan-shaped plate 535, the air guide mesh plate 536 and the isolation rotating frame 537. The air flow is discharged by the air guide mesh plate 536 and the compound fertilizer can be gathered at the same time. The rotation of the isolation rotating frame 537 can form a temporary independent cavity at the bottom of the intercepting fan-shaped plate 535, so that the gathered compound fertilizer is no longer affected by the rising air flow and falls downward along the inner wall of the mixed discharge barrel 4 under the action of gravity, so as to complete the mixing and separation of the compound fertilizer.

[0066] Then, through the mutual cooperation among the components of the exhaust hood 524, the water supply cooling box 525 and the cooling flat box 528, the low-temperature circulating water is continuously introduced into the central mixing tower 2 during the compound fertilizer mixing process, thereby fully utilizing the airflow discharged from the top of the mixing and discharging barrel 4, and the evaporated compound fertilizer raw materials gathered on the upper layer of the central mixing tower 2 are re-condensed and gathered by the low-temperature component composed of the heat-conducting vertical rod 529 and the condensation reed 530, and the gathered compound fertilizer raw materials are re-involved in the mixing process inside the central mixing tower 2 by knocking the small block 532, thereby effectively avoiding the sublimated gaseous compound fertilizer raw materials being directly discharged into the atmosphere with the airflow to cause pollution, further improving the environmental protection of the compound fertilizer production process, and optimizing the smoothness of the use of the compound fertilizer production equipment;

[0067] A multi-stage differential circulation discharging mechanism 6 is arranged inside the mixing and discharging barrel 4. The multi-stage differential circulation discharging mechanism 6 is used to stir the mixed compound fertilizer layer by layer and perform auxiliary granulation in the process of the compound fertilizer descending layer by layer, so as to realize the discharging and transportation of the compound fertilizer;

[0068] The multi-stage differential circulating discharge mechanism 6 includes an intercepting circular plate 601, a discharge notch 602, a mounting annular frame 603, a driving inner gear ring 604, a discharge scraper 605, a telescopic glue stick 606, a guide lifting ring 607, a driven arc block 608, a driving annular frame 609, a driving outer gear ring 610, a transmission gear 611, a driving arc block 612, a rotating discharge scraper 613 and a discharge bottom bucket 614;

[0069] An intercepting circular plate 601 is evenly and evenly fixedly installed at the bottom of the spray ring box 540 on the inner side of the mixing and discharging barrel 4, and a discharging notch 602 is evenly and evenly penetrated on the top surface of the intercepting circular plate 601 in the circumferential direction. A mounting annular frame 603 is fixedly installed at the inner wall of the mixing and discharging barrel 4 corresponding to the top position of the intercepting circular plate 601. A driving inner gear ring 604 is slidably embedded in the inner ring of the mounting annular frame 603, and a discharging scraper 605 is evenly and evenly fixedly connected to the bottom edge of the driving inner gear ring 604.

[0070] The top edge of the mounting ring frame 603 is evenly and evenly fixedly connected with telescopic glue sticks 606 along the circumferential direction, the top surfaces of the multiple telescopic glue sticks 606 are evenly and evenly fixedly connected with a material guide lifting ring 607, and the inner circle of the bottom surface of the material guide lifting ring 607 is evenly and evenly fixedly connected with a driven arc block 608 along the circumferential direction;

[0071] A driving ring frame 609 is fixedly sleeved uniformly and equidistantly along the axial direction at the outer side of the discharge shaft 534 corresponding to the bottom position of the guide lifting ring 607, and a driving outer gear ring 610 is fixedly sleeved on the outer side of the driving ring frame 609. A transmission gear 611 is rotatably installed at the position between the driving outer gear ring 610 and the driving inner gear ring 604 at the bottom of the guide lifting ring 607. A driving arc block 612 is fixedly installed uniformly and equidistantly along the circumferential direction on the edge of the top surface of the driving ring frame 609. A rotating discharge scraper 613 is fixedly connected to the bottom end of the discharge shaft 534, and a discharge bottom bucket 614 is fixedly connected to the middle of the bottom end of the mixing discharge barrel 4. Arc grooves are evenly opened on the top surface of the intercepting circular plate 601, and the bottom surface of the discharge scraper 605 is tightly slidably fitted with the top surface of the intercepting circular plate 601. The thickness of the transmission gear 611 is greater than the thickness of the driving outer gear ring 610 and the driving inner gear ring 604. The bottom surface of the discharge scraper 613 is tightly slidably fitted with the bottom surface of the inner wall of the mixed discharge barrel 4. The mutual cooperation between the components inside the multi-stage differential circulation discharge mechanism 6 optimizes the discharge process of the compound fertilizer. The structural design of the multi-stage interception circular plate 601 effectively avoids the compound fertilizer from falling vertically too fast inside the mixed discharge barrel 4 and raising dust to pollute the surroundings of the production equipment. While the compound fertilizer falls downward layer by layer, the discharge scraper 605 scrapes the compound fertilizer, and the spray ring box 540 and the spray head 541 humidify the compound fertilizer. The scraping of the discharge scraper 605 cooperates with the arc groove on the interception circular plate 601 to preliminarily granulate the compound fertilizer, so as to prevent the compound fertilizer from being too loose and adhering to the conveyor belt and causing loss during the subsequent transportation process, thereby effectively improving the subsequent transportation process of the compound fertilizer.

[0072] At the same time, the inner gear ring 604, the outer gear ring 610 and the transmission gear 611 cooperate with each other, so that the discharge shaft 534 can drive the discharge scraper 605 to rotate slowly during the rotation process, thereby effectively avoiding the discharge scraper 605 from rotating too fast and rubbing against the intercepting circular plate 601 for a long time and causing serious heat, thereby effectively avoiding the secondary volatilization of the compound fertilizer during the discharge process due to the excessively high ambient temperature, thereby ensuring the smooth discharge process and further optimizing the unloading process of the compound fertilizer.

[0073] Working principle and use process of the present invention: In the process of processing compound fertilizer, the present invention needs to first transport the raw materials to be used to the vicinity of the driving base 1, and then add the raw materials to the conveyor belt, and add the raw materials to the upper hopper 504 through the conveyor belt, and then drive the discharge roller 506 to rotate continuously through the discharge motor 505 on the side of the discharge transverse tube 503, and during the rotation of the discharge roller 506, the raw materials in the upper hopper 504 are quantitatively and uniformly added to the guide inclined tube 502, and after each raw material enters the guide inclined tube 502 and the feeding transverse tube 501, the feeding dragon 508 is driven to rotate continuously through the feeding motor 507 at the end of the feeding transverse tube 501, and during the continuous rotation of the feeding dragon 508, the raw materials in the feeding transverse tube 501 are uniformly added to the central mixing tower 2;

[0074] And while the raw materials are added into the central mixing tower 2, a continuous upward airflow is generated in the central mixing tower 2 by driving the fan inside the base 1. Under the action of the upward airflow, the small-particle raw materials will rise along the center mixing tower 2 under the action of the airflow, while the heavier large-particle raw materials will directly fall to the top of the limiting cone net 517, and the large-particle raw materials will be guided by the limiting cone net 517 to the inside of the guide cone tube 513, and then the large-particle raw materials will be introduced into the gap between the grinding ring cover 515 and the conical grinding wheel 512 through the grinding ring cover 515, and the conical grinding wheel 512 and the cleaning scraper 516 will be driven to rotate continuously by the rotating motor 511, and the raw materials accumulated on the top of the grinding ring cover 515 will be scraped during the rotation of the cleaning scraper 516 to prevent the raw materials from accumulating on the top of the grinding ring cover 515;

[0075] Then, after the large particles of raw materials enter the gap between the conical grinding wheel 512 and the grinding annular cover 515, the large particles of raw materials are ground and refined by the conical grinding wheel 512 and the grinding annular cover 515, and the ground and refined raw materials are discharged to the top of the intercepting annular net 510 through the discharge bottom 514, and the ground raw material powder is driven by the high-speed airflow to pass through the limiting cone net 517 and rise along the inside of the central mixing tower 2;

[0076] The raw materials continue to rise under the drive of the airflow, and synchronously drive the driving blades 543 and the transmission vertical shaft 520 to rotate during the rising process of the airflow, and drive the transmission vertical shaft 520 to perform auxiliary rotation through the auxiliary rotating motor 519 installed on the top of the top seat 518, so as to ensure that the rotation speed of the transmission vertical shaft 520 can meet the requirements, and the disturbance blades 522 installed on the outside of the sleeve 521 will also rotate synchronously under the drive of the rising airflow. Since the rotation directions of the disturbance blades 522 are different, a disordered disturbance airflow can be formed on the upper layer of the central mixing tower 2, so as to drive the powder raw materials to be continuously mixed through the disordered airflow, and the mixed raw materials are transported to the inside of the mixing discharge barrel 4 through the material guide cross pipe 3;

[0077] When the mixed compound fertilizer enters the mixing and discharging barrel 4, the compound fertilizer powder in high-speed transportation can be intercepted by the intercepting fan-shaped plate 535 and the air guide mesh plate 536, and the high-speed airflow passes through the air guide mesh plate 536 to enter the exhaust round cover 523 and is discharged outward through the exhaust square cover 524. When the compound fertilizer accumulates at the bottom of the intercepting fan-shaped plate 535 and the air guide mesh plate 536, the transmission vertical shaft 520 will synchronously drive the discharging shaft 534 to rotate through the transmission belt 542, and during the rotation of the discharging shaft 534, the discharging shaft 534 will be driven to rotate. During the process, the isolation rotating frame 537 and the discharge film 538 are synchronously driven to rotate, and the fertilizer adhering to the bottom of the intercepting sector plate 535 and the air guide mesh plate 536 is scraped off by the discharge film 538, and during the rotation of the isolation rotating frame 537, the fertilizer located at the bottom of the air guide mesh plate 536 is transported to the bottom of the intercepting sector plate 535. When the isolation rotating frame 537 drives the compound fertilizer away from the port of the material guide cross pipe 3 during the rotation, the compound fertilizer will gradually fall downward along the mixing discharge barrel 4 under the action of gravity to complete the mixed transfer of the compound fertilizer;

[0078] While the fertilizer powder is being mixed, the external clean water is introduced into the water supply cooling box 525 through the water inlet front pipe 526. When the clean water flows through the water supply cooling box 525, the airflow discharged from the exhaust hood 524 is rapidly cooled to reduce the temperature of the circulating clean water. Then, the low-temperature clean water is introduced into the cooling flat box 528 through the water guide pipe 527. When the low-temperature clean water flows through the cooling flat box 528, the heat-conducting vertical rod 529 and the condensation reed 530 are continuously cooled. The cooling water is discharged through the drainage side pipe 533. The cooling water in the flat box 528 is discharged, so that the condensation reed 530 can keep the low temperature at the top of the central mixing tower 2. When the volatilized raw materials in the fertilizer raw materials are driven to the outside of the condensation reed 530 by the airflow, they will be quickly condensed. Then, the transmission vertical shaft 520 will synchronously drive the rotating frame 531 and the small block 532 to rotate. In the process of the small block 532 rotating, the condensation reed 530 is moved, so that the condensation reed 530 can shake off the condensed raw materials under the action of vibration, so that the raw materials can be re-involved in the fertilizer mixing.

[0079] When the mixed fertilizer is transported from top to bottom along the inside of the mixing and discharging barrel 4, the circulating clean water in the drainage side pipe 533 is introduced into the inside of the spray ring box 540 through the spray conduit 539, and the circulating clean water is evenly sprayed into the mixing and discharging barrel 4 through the spray head 541 to increase the water content of the fertilizer in the mixing and discharging barrel 4;

[0080] When the fertilizer is evenly accumulated on the top of the intercepting circular plate 601, the driving ring frame 609 is driven to rotate through the discharge shaft 534, and the driving outer gear ring 610 and the driving arc block 612 are synchronously driven to rotate during the rotation of the driving ring frame 609. During the rotation of the driving arc block 612, the driven arc block 608 is extruded to drive the material guide lifting ring 607 to rise and fall along the inner wall of the mixing discharge barrel 4, and the telescopic glue stick 606 is synchronously driven to retract and store energy during the lifting and lowering of the material guide lifting ring 607, and then the telescopic glue stick 606 is used to assist the material guide lifting ring 607 to vibrate and rise, so as to prevent the fertilizer from accumulating on the top of the material guide lifting ring 607;

[0081] Then, the driving gear 611 is driven to rotate by the rotation of the driving outer gear ring 610, and the driving inner gear ring 604 is driven to rotate synchronously during the rotation of the driving gear 611. The driving gear 611 can also continuously maintain the meshing between the driving inner gear ring 604 and the driving outer gear ring 610 while rising and falling with the guide lifting ring 607. The driving inner gear ring 604 can synchronously drive the rotation of the discharging scraper 605, and during the rotation of the discharging scraper 605, the fertilizer on the top of the intercepting circular plate 601 is scraped to the top of the discharging slot 602, so that the fertilizer can fall down layer by layer through the discharging slot 602, and during the scraping of the discharging scraper 605, the intercepting circular plate 601 is cooperated to quickly granulate the fertilizer, so that the fertilizer forms a simple granular structure. When the fertilizer falls to the bottom of the mixing and discharging barrel 4, the discharging scraper 613 is rotated to move the fertilizer into the discharging bottom bucket 614 to realize the discharging of the fertilizer.
