Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer storage bins, in particular to a fertilizer storage bin. Background Art

[0002] Storage silos are used to store fertilizers in the fertilizer production process. The storage silos are generally composed of a storage silo body and legs. Fertilizers are poured into the silo from the top entrance for storage. When unloading, the fertilizer is unloaded from the hopper when the switch valve is opened. However, when the fertilizer is stored in the storage silo body for too long, under the influence of gravity and the properties of the fertilizer, the fertilizer is easy to clump into agglomerates, resulting in the fertilizer not being able to fall by its own gravity during the unloading process.

[0003] In order to solve the above technical problems, a Chinese utility model patent with the authorization announcement number CN220115283U discloses a fertilizer storage silo. The scheme is to rotate and connect the annular frame at the bottom of the storage silo body, and use the driving assembly to drive it, so that the cage-shaped bracket can stir the inside of the storage silo body, stir the agglomerated fertilizer and drop it, and the rotating shaft and stirring rod can penetrate deep into the storage silo body to prevent the fertilizer from agglomerating and falling. However, this scheme still has shortcomings: the stirring structure composed of the cage-shaped bracket and the stirring rod has a large gap and a single movement mode, which is only enough to achieve horizontal rotation. Some agglomerated fertilizers cannot contact the cage-shaped bracket and the stirring rod, so the fertilizers cannot be fully stirred, and the clearing effect is poor. Utility Model Content
