Abstract: This study developed a lift-type winged chisel plow-straw-soil interaction model, and its validity was confirmed through multiple experimental indicators obtained from both soil bin tests and simulation experiments. The Discrete Element Method (DEM) was employed to analyze soil disturbance behavior and straw incorporation performance. Results showed that the plow tip of the lift-type winged chisel plow effectively sheared, loosened, and fractured the plow pan soil, while the soil-lifting plate pushed and turned the soil, promoting thorough mixing of straw and soil. Compared to traditional designs, the addition of wings increased the working width, and the soil-lifting plate significantly enhanced the frequency of straw–soil disturbance and soil fragmentation - resulting in a mixing rate of 42.98% and a uniformity rate of 92%.
