Abstract: In order to solve the difficulty of mechanized high quality picking of blueberry, this paper presents a method of crankslider mechanism combined motion picking with rotary motion. Through the construction of the vibration complex motion model, the optimal operation parameters of the vibration were obtained. Combined with the design and analysis of the length and deflection of the rubber rod, the key component of the vibration, the change curve of the acceleration of the end point was simulated by MATLAB software. A crossbank platform was used to integrate key components and a validation test was carried out with rabbiteye blueberry as the harvest object. The experiment showed that when the stick length was 325 mm, the cross section diameter of the stick was 10 mm, the rated speed of the rotation motor was 40 r/min, and the rated speed of the reciprocating vibration motor was 380 r/min, the picking demand could be met, and the picking rate of ripe blueberries could reach 87.11%, and the damage rate was less than 6.54%, which met the picking indexes of relevant harvesting machinery. It has certain guiding significance for the study of high efficiency and low consumption harvesting of blueberry.
