【 摘 要 】

In order to reduce the tillage resistance in the subsoiling process of soil, this paper uses a three-dimensional laser scanner to obtain the data point cloud on the outer surface of Hawaiian shellfish, and performs curve fitting, and designs 14 bionic ribbed subsoilers with different shapes according to the fitting function. In order to analyze the drag reduction effect of various subsoiling shovels, the average tillage resistance of 14 bionic subsoiling shovels and non-bionic subsoiling shovels with smooth surfaces was calculated. The results show that the tillage resistance of bionic subsoiling shovels is less than that of non-bionic subsoiling shovels, the drag reduction effect of 45 degrees rib angle is better than 30 degrees and 60 degrees, the drag reduction effect is better when the rib width is 30mm, and the number of ribs has no obvious difference.
