Abstract

A software model (code) was developed using (MATLAB) in order to model the factors affecting the potato harvesting machine, the most important of which is the penetration angle (attack), and to choose the optimal angle in clay soil types, at different depths and three speeds of the traction machine,Proper angle calibration results in the lowest qualitative and quantitative losses of the drum, while maintaining quality and productivity within the required capacity of the traction machine. Modeling results showed that qualitative losses are lowest in the optimum traction speed zone (3-4.5 km/h) and optimum depth (22-28 cm), while the quantitative losses are lowest (4-5%) in clayey soil.The lower the depth, the higher the optimum angle, and vice versa, i.e. the higher the depth, the lower the optimum angle: Small depths (20-25 cm) have larger angles (40°-50°) - Medium depths (25-35 cm) have medium angles (30°-40°) - Large depths (35-40 cm) have smaller angles (25°-35°). The optimum range for penetration angle: (30°-40°) for most working conditions in clay soil, and it varies according to depth: the greater the depth, the lower the optimum angle, and the lower the quantitative and qualitative loss of tubers is achieved.
