Chinese wolfberry is an excellent tonic, it has very good nourishing and treatment effect. Recent years, more and more people are beginning to recognize the value of wolfberry and the demand of wolfberry is increasing. At present, the main collection mode of Chinese wolfberry is still artificial picking, but the efficiency of artificial picking is low and the cost is high. Except for artificial picking, there are mainly two types of mechanical harvesting: comb type and vibration type. Through literature research, it was found that vibration type is more efficient and lower cost. Therefore, according to the growth characteristics of fruiting branches of Chinese wolfberry, the wolfberry fruit shedding condition was analyzed, the kinematic model of fruit abscission was established and a vibrating wolfberry harvester was designed. The parameters of device that affected the falling of fruit were vibration frequency, amplitude and finger spacing by solving the model through ADAMS. Then the orthogonal experiment was done by different vibration frequencies, different amplitudes and different finger spacings. The optimum combination of structural parameters was as follows: vibration frequency of 12Hz, amplitude of 40mm and finger spacing of 100mm. Under this condition, the harvesting rate of ripe wolfberry was 93.52%, the harvesting rate of unripe wolfberry was 5.72%, and the damage rate of ripe wolfberry was 2.54%, the harvesting efficiency was 485g/min and the harvesting efficiency of vibrating wolfberry harvester was about 5.5 times of artificial picking efficiency. Thus the vibrating wolfberry harvester can meet the quality requirements of farmers.
