Design and Experiment of Hand-Push Vibration Picking Machine of Lowbush Blueberry

Abstract

As plants of lowbush blueberry are widely cultivated, picking of blueberry has become an important link in the chain of blueberry industry. At present, research of domestic machinery of blueberry picking is still in early stages. Mechanical and automation level of blueberry picking are enriched, through research of picking machine of lowbush blueberry. The research has the vital significance to the development of blueberry industry. To improve picking efficiency and reduce total loss rate of green fruit, mechanism of picking is analyzed. Fruit, which has certain representativeness in the variety, is researched. Picking force and vibration frequency of plants are obtained and work principle is determined. Structures of vibrating picking and fruit collection and the body of the machine are designed. Parameters of structure size and working are determined, with which the machine is manufactured. Plan of experiment is designed and experiment of picking is done in the season blueberries are most ripe. Result indicates structure of blueberry picking machine is reasonable. Picking force and vibration frequency are effective. Compared with that of manual picking, efficiency of mechanical picking is high, which meets technical requirements of blueberry machinery.
