Description

Technical Field

[0001] The utility model belongs to the technical field of controlled-release fertilizer production, and specifically relates to a granulator for controlled-release fertilizer production. Background Art

[0002] Controlled-release fertilizer is an advanced form of slow-release fertilizer. It mainly controls the release of nutrients through coating technology to achieve the goals of safety, long-term effectiveness and high efficiency. It is the main direction of modern fertilizer development and is suitable for mechanized production, especially to meet the needs of sowing seeds and fertilizers at the same time. During the production process, the raw materials need to be mixed with other substances to form granules under the action of a granulator for easy fertilization.

[0003] After searching, the Chinese utility model patent with announcement number CN216879224U discloses a granulator for the production of potassium humate type controlled-release fertilizer, including a granulator box, a transmission extrusion mechanism, a pressing mechanism and a slicing mechanism; the granulator for the production of potassium humate type controlled-release fertilizer can utilize the vertical feeding method of the auger wheel, and cooperate with the interlocking cylinder at the middle end of the pressing plate to prevent the raw materials from falling onto the pressing plate when the pressing plate is pressed and causing accumulation, and cooperate with the scraper at the bottom end that is synchronously driven with the auger wheel to push the fertilizer particles to assist the fertilizer discharge.

[0004] The above scheme still has the following technical problems when used. For example, the raw materials transported between the granulation plate and the pressing plate can only be distributed on the surface of the granulation plate by relying on their own fluidity, which will result in the raw materials being unable to be completely distributed on the surface of the granulation plate. During extrusion, it will cause uneven extrusion and uneven granulation.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies.

[0006] Therefore, in order to solve the above problems, the utility model provides a granulator for producing controlled-release fertilizer. Utility Model Content

When injecting the material, the movable baffle can block the opening of the bottom trough to prevent the material from entering the bottom trough. During extrusion, the scraper is first rotated to align with the bottom trough, and then the material is extruded by descending the scraper, and the granulation work is completed in cooperation with the granulating plate and the rotating slicing plate. When the scraper descends, the movable baffle can be squeezed into the bottom trough by the scraper to avoid affecting the subsequent granulation operation.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0009] A granulator for producing controlled-release fertilizers comprises a granulator box, a box cover is installed on the granulator box, a granulator plate is installed inside the granulator box, a lifting and lowering pressing plate is arranged above the granulator plate, a bottom groove is opened at the bottom end of the pressing plate, a movable baffle is arranged inside the bottom groove, a rotatable scraper is arranged between the granulator plate and the pressing plate, the size of the scraper matches the size of the bottom groove, a rotatable slicer is arranged below the granulator plate, the material injected between the granulator plate and the pressing plate can be scraped flat by the scraper, so as to ensure the uniformity of the particles during subsequent granulation, when injecting materials, the movable baffle can block the opening of the bottom groove to prevent the materials from entering the inside of the bottom groove, when extruding, the scraper is first rotated to the bottom groove to align with it, and then the materials are extruded by descending the scraper, and the granulation work is completed in cooperation with the granulator plate and the rotating slicer, and when the scraper descends, the movable baffle can be squeezed into the bottom groove by the scraper to avoid affecting the subsequent granulation operation.

[0010] Furthermore, a motor is fixedly mounted on the top of the box cover, and a rotating rod is mounted on the output end of the motor.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the utility model, in the initial state, the scraper and the bottom trough are staggered, at this time, the movable baffle is located at the opening of the bottom trough, and the bottom surface of the movable baffle is flush with the bottom surface of the pressing plate. At this time, the movable baffle can block the opening of the bottom trough to prevent the material from entering the interior of the bottom trough. The material is injected into the space between the granulating plate and the pressing plate through the injection hopper and the telescopic tube. In the process of injecting the material, the motor drives the rotating rod to rotate, and the rotating rod drives the scraper to rotate. The rotation of the scraper can scrape the material flat. When a certain amount of material is injected, the scraper is first rotated to the bottom. The troughs are aligned, and then the pressure plate is driven down by the hydraulic rod. When the pressure plate descends, the scraper squeezes the movable baffle. At this time, the telescopic support and the spring are compressed until the scraper enters the bottom trough completely. As the scraper continues to descend, the material is squeezed, and the granulation work is completed with the cooperation of the granulating plate and the rotating slicing plate. The cut fertilizer particles fall to the inner surface of the granulator box, and then the hot air is blown into the inside of the granulator box by the hot air blower. The hot air can not only blow the fertilizer particles out of the granulator box, but also heat and dry them. BRIEF DESCRIPTION OF THE DRAWINGS
