Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fertilizer production, and specifically relates to an automatic proportioning and stirring equipment for mixed fertilizer production. BACKGROUND

[0002] Mixed fertilizer, also known as formula fertilizer or BB fertilizer, is a mixture of various raw materials, which is formed by mixing two or more single-element fertilizers or compound fertilizers with similar particle sizes in a certain proportion through simple mechanical mixing.

Therefore, the air jet of the air outlet pipe is only at the same height, which can easily cause the material near the height to be disturbed by strong airflow, while the material in other parts of the stirring box is less affected. This can lead to uneven distribution and mixing of the material in the stirring box. SUMMARY
