【Abstract】 To provide key harvesting technology support for the research and development of large-scale Lycium barbarum harvesting technology and equipment. In this paper, firstly, vibration, pneumatic, roll brush and shearing methods of Lycium barbarum harvesting are selected. Then, the related test equipment is designed. Next, the test scheme for these test equipment is formulated, the harvesting effect test of Lycium barbarum was carried out. The results show that the damage rate of Lycium barbarum harvested by reciprocating high frequency vibration is between 5% and 9%, the net recovery rate is between 85% and 95%, and the high frequency vibration frequency is between 33 Hz and 38.3 Hz,harvesting effect is so good. The damage rate of vibroflotation is 9%～40%, the net recovery rate is 50%～70%, and the effect of shaping vibration head is better. The damage rate of Lycium barbarum harvested by barotropic turbulence is between 4% and 13%, which requires high pressure. The damage rate of Lycium barbarum harvested by negative pressure method is between 6% and 15%, and the net recovery rate is 90%～100%, the oblique thrust combined with negative pressure extraction has a better effect; the damage rate of roller brush harvest method is between 4%～16%. The shear harvesting for the damage rate can be neglected, which is easy to be mistaken and difficult to harvest. Finally, vibration and pneumatic harvesting methods can provide important reference for the research and development of self-propelled Lycium barbarum continuous harvesting equipment. In conclusion, the reciprocating high frequency vibration, shock vibration and barotropic turbulence methods can be applied to the research and development of large-scale Lycium barbarum harvesting equipment.更多还原
