【摘要】：以2ZB-2型吊杯式移栽机为试验装置,以一次地轮与土壤接触区为研究单元,由薄膜压力传感器及配套的数据采集卡构成数据采集系统,在移栽机稳定工作状态下采集移栽机地轮与土壤的相互作用力,获得基于土壤硬度变化时地轮与土壤正压力模型,分析在不同土壤硬度条件下地轮-土壤接触区域相互作用力的变化趋势。田间试验结果表明:同一土壤硬度下随着地轮的移动,在地轮正下方位置应力值最大;地轮同一截面正应力值大小基本相同,且变化趋势基本相同;随着土壤硬度的增加,应力值逐渐增大。通过对地轮与土壤相互作用力的研究,可为移栽机栽植效果的提高提供依据。
[Abstract]:A data acquisition system was made up of a thin film pressure sensor and a matching data acquisition card with 2ZB-2 type hoisting cup transplanter as the experimental device and the primary ground wheel and soil contact area as the research unit. Under the steady working condition of the transplanter, the interaction forces between the ground wheel and the soil of the transplanter were collected, and the model of positive pressure between the ground wheel and the soil was obtained based on the change of soil hardness. The variation trend of the interaction between ground wheel and soil contact area under different soil hardness was analyzed. The results of field experiments show that the stress value is the largest under the ground wheel with the movement of the ground wheel under the same soil hardness, the normal stress value of the same section of the ground wheel is basically the same and the variation trend is basically the same, and with the increase of the soil hardness, The stress value increases gradually. The research on the interaction force between the ground wheel and the soil can provide the basis for improving the planting effect of the transplanter.
