Description

Agricultural fertilizer mixing arrangement

Technical Field

The utility model relates to the technical field of fertilizer processing, in particular to an agricultural fertilizer mixing device.

Background

The mixed fertilizer is prepared by mixing two or more simple substance fertilizers or compound fertilizers with similar particle sizes as raw materials according to a certain proportion by simple machinery, and is a mixture of various raw materials. Because the compound fertilizer is prepared with nutrient contents such as nitrogen, phosphorus, potassium and the like according to the growth requirements of various crops, auxiliary materials are required to be added into the fertilizer, the mixed fertilizer is fully stirred and uniformly mixed to reach proper concentration, and in the production and blanking process of the existing mixed fertilizer, the problem that the blanking quantity of each raw material cannot be controlled and the formula of each raw material is disordered cannot meet the actual production requirements exists.

At present, the stirrer appearing on the market is that the stirring shaft is installed in the middle of the stirring barrel, the stirring shaft is formed by combining stirring blades fixed on a rotating shaft, the stirring blades are generally perpendicular to the rotating shaft and are arranged as a transverse shaft, and the rotating shaft is driven by a motor to rotate so as to drive the transverse shaft to perform circular motion around the rotating shaft, but the stirring structure is limited in one direction, and stirring blind areas exist in other directions, so that the problem that large particles are possibly clamped in materials after stirring is caused, and the mixing uniformity of the mixed fertilizer is influenced.
