Blending device for liquid fertilizer

The utility model relates to the field of liquid fertilizer blending equipment, in particular to a liquid fertilizer blending device which comprises a barrel, an air pump mechanism is mounted at the bottom of the barrel, and a plurality of airflow pipes are mounted between the outside and the inside of the barrel and connected with one end of the air pump mechanism. The stirring motor for stirring and fusing is mounted in the barrel, the feeding pipes are mounted at the top of the barrel, different raw materials can be fed into the barrel, and when original fertilizer left at the inner bottom end and on the inner wall of the barrel cannot be completely stirred and fused in the stirring process of the stirring motor, the raw materials can be fed into the barrel through the feeding pipes. The air pump mechanism can be started to generate air flow, and the air flow is blown out from the bottom of the barrel and the inner wall of the barrel through the air pump mechanism, so that the original fertilizer and the s
