Design and experiment of hand-push lowbush blueberry picking machine

To realize the mechanization of blueberry harvest and reduce the workers’ labor intensity, a hand-push picking machine for the lowbush blueberry was designed. The design basis was got by analyzing the mechanism of the harvesting machine, and then the simulation of the key parts was did with ADAMS to determine working parameters of the picking mechanism, according that, the transmission system could be designed. At last the picking machine was made. The experimental data were obtained from the picking experiments using the prototype. The picking rate of one machine was 12 kg/h, and the damage and the clearly picking rates were 10% and 86% respectively. Finally influence factors of the low picking efficiency were summarized and improvement measures were put forward.
