果园采摘机械化(国外英文资料) Present situation and development trend of orchard picking machinery China is the worlds largest fruit producer and the largest fruit consumer in the world. The rapid development of fruit farming has promoted the market demand of orchard machinery. The labor force used in picking operations accounts for 33% to 50% of the labor force used in the whole production process. At present, most of the fruit picking in China is mainly manual picking. The picking operation is complex, highly seasonal, if the use of artificial picking, not only low efficiency, large amount of labor, but also easy to cause fruit damage, if not enough manpower can not be picked will lead to economic losses. The use of picking machinery not only improves the picking efficiency, but also reduces the damage rate, saves labor costs, and improves the economic benefits of the fruit growers. It is of great significance to improve the mechanization of the harvesting operations. First, the status of foreign orchard picking machinery 1. mechanical picking orchard mechanical picking, mainly vibration, rocking, impact and cutting three types. Shake is the use of external force to the tree branches or vibration or shaking, the fruit produced in the weakest link of acceleration, and the separation of fruit drop. Percussive impact member is a direct collision branch or beat vibration traction of the fruit fall fruit trellis. Cutting is the way to cut branches or fruit trees to separate fruit from fruit trees. It is also divided into mechanical cutting and power cutting. The study of orchard picking machinery began in the early 40s of last century, and the western countries led by the United States, France and Britain started this research earlier. In mid 40s the United States began to study shaking picking machine, used for picking walnuts and apricots and other fruit, by the middle of 50s, by shaking the fruit harvesting fruit picking machine has been developed and widely used in Europe and th
