Abstract

Burying straw into the field is the most direct and effective method for straw utilization. This research enables deep soil fertilization and interval deep loosening. To enhance the efficiency of deep straw burial and returning, as well as the straw cleaning rate, a concave straw guiding device was designed and installed on a side-sweeping type straw returning machine. Based on relevant literature and design requirements, theoretical analysis and calculations were performed for the concave straw guiding plate. The calculated range for the guiding plate deflection angle (β) was 0° ≤ β ≤ 32.08°, and the range for the guiding device inclination angle (θ) was 25.89° ≤ θ ≤ 66.8°. Considering practical processing and installation constraints, the deflection angle β was selected as 30° within the specified range, and the inclination angle θ was set at 45°.
