木薯形态及其收获起拔力分析

Analysis of Uprooted Force and Morphology on Cassava

为了得到木薯机械化收获中的挖拔零部件的设计参数和木薯全株各种形态特征之间的关系,采用了实地田间抽样的调查统计方法,对木薯关键形态特征(全株重量、根块俯视投影面积,茎秆截面面积)进行了统计分析。以统计数据和相关公式计算为前提,进行数学建模,得出可靠的木薯块根的最大起拔力。结合木薯的主要形态特征和最大起拔力要求,可为挖拔式木薯收获机提供设计参考数据。

In order to explore the relationship between design parameter on the digging component of Cassava Machine and the morphological characteristic of Cassava. Firstly , the key morphological characteristic of Cassava （ the weight , the root＇ s acreage of vertical view , the cross section of stem） was determined the testing date and correlation formula to begin mathematical modeling for calculating the mix uprooted force . Researching the key morphological characteristic of Cassava and demand of uprooted force provides parameter basis for the design of digging-Cassava harvest Machine.
