Description

Technical Field

[0001] The present application relates to the technical field of fertilizer production, and in particular to a fertilizer granulation mechanism for fertilizer production. Background Art

[0002] Fertilizers are substances that provide one or more essential plant nutrients, improve soil properties, and increase soil fertility. They are one of the material foundations of agricultural production. They primarily include ammonium phosphate fertilizers, water-soluble macronutrient fertilizers, medium-nutrient fertilizers, biofertilizers, organic fertilizers, and multi-dimensional field-energy concentrated organic fertilizers. Granulators are used in the fertilizer production process.

[0003] Patent No. CN221514403U discloses a fertilizer granulation mechanism for fertilizer production. The fertilizer granulation mechanism for fertilizer production drives the pressure plate to move downward by starting two hydraulic cylinders to flatten the fertilizer raw materials, and then starts the servo motor to drive the baffle to move to the right to remove the obstruction of the extrusion hole, and then starts the dual-axis stepper motor to drive the pressure plate to move down to a fixed height. When the pressure plate moves down, a fixed amount of fertilizer raw materials will be extruded from the extrusion hole, thereby squeezing the fertilizer raw materials into strips and extending a fixed length downward at the bottom of the partition. Then, the servo motor is started to rotate in the opposite direction to cut the strip fertilizer raw materials extending to the bottom of the partition to form fertilizer particles. Since the cross-sectional size and length of the fertilizer particles are equal, the purpose of uniform particles is achieved. However, since the fertilizer raw materials are poured into the box through the feed hole of the granulation mechanism, the raw materials will be piled up in a cone shape. During the pressing process, the fertilizer is unevenly stressed due to the uneven top of the raw materials, resulting in some raw materials remaining, affecting the fertilizer extrusion effect and prolonging the granulation time.
