摘要
荸荠的生长环境特殊,收获仍旧采用传统手工挖掘,劳动效率低,劳动强度大,难以挖净,而薯类收获机械又难以适应水田荸荠的收获,通过对荸荠生长地的土壤成分分析,基于土壤液化原理,搭建了小型实验平台,对荸荠挖掘机理进行了试验模拟。提出了一套适用于水田作物荸荠机械挖掘、筛分的流程,并对挖掘原理进行了实验探究。根据实验数据分析,获得了影响荸荠收获的主要因素。研究表明利用土壤液化原理可以使砂壤土液化,为该原理用于荸荠采收提供依据,为荸荠挖掘机样机的试制提供设计参考。
Water chestnut grows in a special environment, and its harvest still relies on the traditional manual mining. The labor efficiency is low, and labor intensity is big. It is difficult to dig net. When as, it is difficult for potato harvest machinery to adapt to the rice field to harvest water chestnut. By analyzing the composition of soil where water chestnut grows in, a small experimental platform was built to carry out a test simulation of the mechanism of water chestnut digging according to the principle of soil liquefaction. A set of process suitable for rice paddy crop water chestnut mechanical mining and screening was put forward, and the theory of digging was explored. According to the analysis of experimental data, the main factors affecting water chestnut harvest have been obtained. The research showed that sandy loam can be liquefied by using the principle of soil liquefaction. The study provided a basis for the principle used for water chestnut harvest and provided design reference for water chestnut excavator prototype trial.
