Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer granulation equipment, in particular to a granular fertilizer granulation device. Background Art

[0002] The fertilizer granulating device for the production of organic granular fertilizer is a kind of device used in the production process of organic fertilizer. After the fertilizer powder is produced, the organic fertilizer is granulated to facilitate the bagging and drying procedures in the later production steps, and to facilitate the later transportation, thereby improving the convenience of applying organic fertilizer in the agricultural production process.

[0003] Through searching, CN215312177U was found, which discloses a fertilizer granulating device for organic fertilizer production, whose structure includes an extrusion mechanism and a drying mechanism. The fertilizer is put into the mixing drum through the feeding port, the rotating motor drives the rotating rod to rotate, and then the stirring blades stir the fertilizer. The stirred fertilizer passes through the lower end of the screening net, and then is stirred by the stirring rod, and then enters the extrusion drum through the discharge port. The hydraulic cylinder pushes the pushing plate to make the fertilizer extrude through the forming hole, and then it falls into the upper end of the conveyor belt after being cut by a blade, and then it is heated and dried by a heating pipe, and then discharged through the discharge port. The existing fertilizer granulating device solves the problem that the subsequent granulation is easily blocked due to the lack of screening of large pieces of fertilizer during the granulation process, and the fertilizer is self-broken during the extrusion process, resulting in different sizes of subsequent particles. In addition, due to the presence of humidity during the extrusion process, viscosity is easily generated during transportation after the granulation is completed, making it difficult to separate the particles.

[0004] The push plate is pushed by the hydraulic cylinder to discharge the fertilizer from the forming hole, which facilitates the forming of granular fertilizer. However, when the hydraulic cylinder is contracted, the forming hole will stop discharging the material, which greatly reduces the granulation efficiency of the granular fertilizer. Therefore, we need a granular fertilizer granulation device. Utility Model Content
