Abstract

The mechanical properties of lavender are the basis for design and study of mechanized equipment for planting and harvesting of lavender. This paper determines and studies the natural width and height of plant and spike length of three kinds of lavender widely planted in the Yili region and obtains the distribution rules of parameters of the basic physical properties of lavender. Meanwhile, the test of the mechanical properties of lavender was done at the moisture content in the harvest period and different moisture contents. The results indicated that the maximum separation force of the flower of three kinds of lavender (111.3N) was much smaller than the minimum breaking force of the stem (201.5N); and the moisture content significantly affected the mechanical properties of lavender, which could provide corresponding design parameters and important theoretical basis for the design of a new lavender harvester based on separation technology.

薰衣草的机械力学特性是设计研究薰衣草种植、收获机械化装备的基础。本文对伊犁地区广泛种植的三种薰衣草的植株自然宽度、自然高度以及花序长度进行了测定研究，获得了薰衣草基本物理特性参数的分布规律。同时，在收获期含水率和不同含水率条件下，进行了薰衣草的力学特性试验。结果表明，三种薰衣草花脱离力的最大值（111.3N）远小于茎拉断力的最小值（201.5N）;含水率对薰衣草的力学特性有显著影响，可为设计基于脱离技术的新型薰衣草收获机提供相应的设计参数和重要的理论基础。
