摘要:

为设计一种合理的振动采集干果的机具,对银杏树果实的果柄结合力进行了测试,对果枝进行了激振试验和振动落果试验,还在室外对立木侧枝进行了振动测试,经过数据处理和分析,得出了银杏侧枝振动落果最佳的激振频率、振动加速度和振动时间,为果树侧枝振动采种机具的设计提供了科学的技术参数和设计依据。

Abstract:

In order to design the reasonable vibrating im plements for harvesting fruits or nuts, the connection force of fruits and their stalk are measured, the experiments of stimulation and dislodging of fruits by vibration on the branches are carried out. The vibrating ex periment on the branches of living tree are done outdoors. At last, the most suitable stimulation frequency, acceleration of vibration, time of vibration were obtained by the analyses of data. The useful technological parameter is offered to the design of implements for shaking the branches of orchard trees todislodge fruits or nuts.
