| Rake angle is a key parameter of subsoiler structural design and has important impacts on subsoiler performance. In this study, the high-speed photographic technique is used to understand the mechanisms by which the rake angle of an arrow subsoiler (angles of 18°, 23°, and 28°) impacts soil crushing. The following results were obtained. (1) Rake angle is the main factor that influences the soil crushing process. Changing the rake angle can induce changes in the interactions between the subsoiler and soil, impacting soil crushing performance. (2) Rake angle has important impacts on the soil disturbance state. The horizontal soil disturbance distance increases and the vertical soil elevation decreases when the rake angle is increased. For a fixed soil... |
