发布时间：2018-12-13 20:21
【摘要】：【目的】减小机器人采摘荔枝时因回收放置不当产生的跌落碰撞损伤。【方法】对荔枝进行跌落碰撞试验,分析不同的跌落碰撞条件对荔枝失质量率及果壳褐变指数的影响。【结果】荔枝失质量率及果壳褐变指数随着采摘回收下放高度的提高和储藏时间的延长而分别增加;相同下放高度,碰撞接触材料为PVC板时,荔枝失质量率及果壳褐变指数最大;试验范围内,回收装置采用塑料框时,储藏2 d机器人采摘回收的最大起始下放高度为60 cm,储藏1周为30 cm;回收装置为瓦楞纸果箱,储藏2 d机器人采摘回收的最大起始下放高度为75 cm,储藏1周为45 cm;回收装置底层布满荔枝后,储藏2 d机器人采摘回收的最大起始下放高度可提高到90 cm,储藏1周可提高到60 cm。【结论】该研究可为荔枝机器人采摘回收放置减损策略的构建提供指导。
[Abstract]:[objective] to reduce the damage of drop collision caused by improper recovery and placement during picking litchi by robot. [methods] drop impact test was carried out on litchi. The effects of different drop impact conditions on litchi mass loss rate and fruit shell browning index were analyzed. [results] the litchi mass loss rate and fruit shell browning index increased with the increase of collecting and recovering height and the prolongation of storage time. When the impact contact material was PVC plate, the litchi mass loss rate and shell browning index were the largest. In the range of the experiment, when the recovery device is plastic frame, the maximum starting and down height of the robot picking and recycling is 60 cm, 1 week and 30 cm;. The recovery device is a corrugated fruit box, and the maximum starting and low height of the robot picking and recovery is 75 cm, for 1 week and 45 cm; for 2 d storage. After the bottom layer of the recovery plant was covered with litchi, the maximum initial down-down height of the robot for 2 days storage could be raised to 90 cm,. Storage for 1 week could be increased to 60 cm. [conclusion] this study could provide guidance for the construction of the reduction strategy of harvesting, recovery and placement of litchi robot.
