该项研究的核心是研制振动器,通过振动果枝的方式来收获沙棘果实。2003到2004年间,基于我们的试验研究结果显示,沙棘品种“印度夏季”通过用频率为40Hz,振幅为15mm,10s为一振动周期的果枝振动器可有效获得果实。利用这个参数的振动可以有效获得90%的果实,且对果枝的损害很小,从果枝上下来的叶片、芽及木枝的碎片也很少。在2003年进行了最原始的研究,2004年测试发现这种方法存在一定缺陷。发电机利用机轴进行来回的旋转运动,利用这个原理进行各种振幅试验,但这对果树各部分会产生大量的压力。用1.5kW的电机可以在车间及没有农业机械的土地上进行试验,但这个过程需要人工看护。最原始的方法效率不高且过程复杂。2005年进行了设备的改进,通过凸轮产生的振动来驱动液压马达。尽管这种方法使用时间还很短,但是它的振动功能还是非常显著的。如果选在最佳采摘季节收获果实,收获的果实品质最佳,同时对果树的伤害也是最小的。如果在每个季节采摘500株或是更少果树的果实,这种振动收获果实的方法是一种最佳选择。
At the core of this research is the development of vibrators that harvest sea buckthorn fruits by vibrating the branches. From 2003 to 2004, the results of our pilot study showed that the seabuckthorn variety “Summer India ” can be effectively obtained by using a fruit vibrator with a frequency of 40 Hz, an amplitude of 15 mm, and a vibration period of 10 s. Vibration using this parameter can effectively obtain 90% of the fruit, and damage to fruit branches is very small, down from the branches of the leaves, sprouts and branches of the wood is also very small. The most original study was conducted in 2003, and the 2004 test found some flaws in this approach. Generators use the crankshaft for back and forth rotary motion, using this principle for various amplitude tests, but this places a significant amount of stress on the various parts of the fruit tree. With a 1.5kW motor, it is possible to test the plant floor and the farmland without agricultural machinery, but this process requires manual care. The original method is inefficient and complicated. In 2005, equipment improvements were made to drive the hydraulic motor through the vibrations generated by the cam. Although this method is still used for a short time, its vibration function is still very significant. If you choose to harvest the fruit in the best picking season, the harvested fruit is of the best quality with minimal damage to the fruit trees. This method of harvesting vibrations is the best choice if picking 500 or fewer fruit trees per season.
