Structural Optimization of the Chise Trenching Subsoiler with Full Layer Fertilization

The trenching subsoiler with full layer fertilization is the key part of the corn precise planter with notillage and full layer fertilization. The current trenching subsoiler with full layer fertilization is generally chiselshaped, which has some problems such as high tillage resistance, narrow section of soiling and poor soil breaking effect, this seriously affected the further improvement of corn. This paper combined the advantages of arrow subsoiler and subsoiler with double wing, conducted structural optimization of the chise subsoiler, and designed a new trenching subsoiler with full layer fertilization, this type of trenching subsoiler has strong penetrating ability,good soil disturbance effect, wider operation section, smaller soil solidity and better subsoiling effect.
