摘要:为研究机械采收蓝莓果实受损原因,明确果实受损程度分布,提高国内机械采收蓝莓的普及率,在分析采收机工作原理的基础上,采用离散元方法研究机械采收过程中的大量果实接触碰撞特性,基于EDEM仿真蓝莓机械采收过程,获得采收过程中果实接触碰撞后的能量变化,通过能量变化值分析果实损伤程度,得到果实无损伤概率为79.33%,发生轻度损伤概率为7.77%,仿真结果表明机械采收过程中大量果实没有发生机械损伤,机械采收可以保证蓝莓果实质量,该研究可为国内机械采收蓝莓的推广提供理论支持。

Abstract:
Abstract:In order to study the causes of mechanical harvesting of blueberry fruits, to determine the distribution of fruit damage and to improve the penetration rate of domestic mechanical harvesting blueberries, based on the analysis of the working principle of harvesting machines, the discrete element method was used to study the mechanical harvesting process. The large number of fruit contact collision characteristics, based on EDEM simulation of blueberry mechanical harvesting process, the energy change after fruit contact collision in the harvesting process, the fruit damage degree was analyzed by energy change value, and the probability of fruit no damage was 79.33%. The probability of damage is 7.77%. The simulation results show that there is no mechanical damage in the process of mechanical harvesting. The mechanical harvesting can ensure the quality of blueberry fruit. This study can provide theoretical support for the promotion of domestic mechanical harvesting of blueberries.
