摘要： To analyze the severe mechanical damage of Fritillaria ussuriensis Maxim (FUM) during drum screening, the sliding speed of the FUM lifting plate, maximum separation angle of the lifting plate, falling height corresponding to the maximum separation angle, and impact energy of FUM on the contact materials of the drum wall were determined by conducting theoretical analysis based on the equations of sliding motion of the FUM mixture along the lifting plate, slanting motion, force balance, and kinetic energy. The maximum separation angle of a FUM mixture was measured by employing high-speed photography, and the theoretical formula was revised. The impact force data was collected using a Model 1199 stress-strain sensor, and the evaluation index of the rela-tionship between the absorbed energy and the impact force was established. The effects of the falling height, collision material, and falling direction on the energy absorption of FUM were analyzed by performing a single-factor test. The results of theoretical and experimental analyses showed that the sliding speed of the FUM lifting plate increased with the increase in the drum's rotating speed and that the falling height and impact energy initially increased and then decreased with the increase in the drum's rotating speed. The absorption energy of FUM increased with the increase in the falling height, but the absorption energy of forward falling and lateral falling had no significant change with mass. The effect of the impact materials (steels plate, FUM, soil, and screening mesh) on the absorption energy of FUM was determined. The percentage of damage and breakage of FUM had a quadratic relation with the impact energy, and their determination coefficients were 0.97054 and 0.99993, respectively. The results of this study can be useful for the optimization of key parameters during the design of a low-loss screening device for FUM harvesting.
