To investigate factors influencing the performance of mulching plastic film collector and determine the optimal working conditions, the theoretical analysis and motion simulation were carried out. By using the soil-bin trolley experiment, the orthogonal experiment with influence factors of machine operating speed, speed ratio (the ratio of spring-tooth axis speed and the speed of machine operating) and the embedded depth of the shovel for lifting film was carried out. Consistent with theoretical analysis, simulative studies demonstrated that the collection ratio of mechanism could reach the optimal when the machine operating speed was 0.7m/s, the speed ratio was 1.0, and the embedded depth of the shovel for lifting film was 110mm.
