Description

Technical Field

[0001] The utility model relates to the technical field of water-soluble fertilizer mixing, in particular to a powder water-soluble fertilizer mixing device. Background Art

[0002] Water-soluble fertilizer is a kind of fertilizer that can be quickly and completely dissolved in water. It can be used in conjunction with agricultural irrigation facilities to achieve water-fertilizer integration in agricultural production. Water-soluble fertilizer is mainly made by mixing a variety of chemical raw materials such as high-purity urea, ammonium phosphate, ammonium nitrate, etc. Most of them are fine powders with strong hydrophilicity. However, when a large amount of water-soluble fertilizer needs to be dissolved, auxiliary mixing equipment is needed to promote the fusion of water-soluble fertilizer and water.

[0003] A powdered water-soluble fertilizer mixing device is disclosed in Chinese patent CN202321863338.0. When the driving motor of the powdered water-soluble fertilizer mixing device is working, it drives the rotating shaft to rotate. The rotation of the rotating shaft drives the crushing teeth to rotate. The agglomerated powdered fertilizer can be crushed by the crushing teeth, which can increase the subsequent water dissolution rate of the water-soluble fertilizer and reduce the water dissolution time of the water-soluble fertilizer. The powdered water-soluble fertilizer mixing device is used for mixing water-soluble fertilizer raw materials. However, in the process of fusing the water-soluble fertilizer with water, when more water-soluble fertilizer is added or there are components that are difficult to dissolve, agglomerates may not be fully mixed with water.
