AI Technical Summary
Existing mixing devices have slow stirring speeds and low efficiency when preparing blended fertilizers, making it difficult to achieve thorough mixing of the fertilizers.
The system employs a premixing box and a horizontal fertilizer mixer. Granular fertilizer is evenly distributed through upper and middle layer spraying mechanisms and falls under gravity, forming a spatial cross-mixing. Combined with a linkage structure driven by a geared motor, it achieves primary and secondary mixing of granular fertilizer.
It significantly improves the uniformity of fertilizer distribution and mixing effect, ensures the quality of blended fertilizer, and improves mixing efficiency.
