摘要/Abstract

摘要： 【目的】研究影响机采棉采摘力学特性的主要因素,为优化水平摘锭式采棉机摘锭结构以及筛选合理棉花采收期提供理论依据。【方法】采用全因子试验设计方法,分析棉花品种、棉花含水率、棉花脱叶时间对棉花与铃壳间分离力、棉花自身扯断力的影响。【结果】棉花含水率、棉花脱叶时间、棉花品种对棉花与铃壳间分离力、棉花自身扯断力的影响均显著(P<0.05),棉花脱叶时间对机采棉采摘力学特性的影响远大于棉花含水率和棉花品种。【结论】随着棉花含水率的提高,棉花与铃壳间分离力逐渐减小,棉花自身扯断力逐渐增大;随着成熟时间增加,棉花与铃壳间分离力、棉花自身扯断力均呈现先增大后减小的趋势,在相同因素水平下,棉花自身扯断力始终大于棉花与铃壳间的分离力。

关键词: 机采棉; 棉花脱叶时间; 棉花含水率; 棉花与铃壳间分离力; 棉花自身扯断力

Abstract: 【Objective】 To explore the main factors that affect the mechanical characteristics of machine-picked cotton in the hope of providing theoretical basis for optimizing the structure of horizontal spindle picker and selecting reasonable cotton harvesting period. 【Methods】 In this paper, a full-factor test design method was used to analyze the effects of cotton varieties, cotton moisture content, and cotton defoliation time on the separation force between cotton and boll shell, and the cotton tearing force. 【Results】 The test results showed that the moisture content of cotton, cotton defoliation time, and cotton varieties had significant effects on the separation force between cotton and boll shell, and the cotton's own tearing force (P <0.05). The effects of the defoliation time are much greater than that of cotton moisture content and cotton varieties. 【Conclusion】 With the increase of the cotton moisture content, the separation force between cotton and boll shell gradually decreases, and the tearing force of cotton itself gradually increases; at the same time, as the maturation time increases, the separation force between cotton and boll shell, and the tearing force of the cotton itself increases first and then decreases, and under the same factor level, the tearing force of cotton itself is always greater than the separating force between cotton and boll shell.

Key words: machine-picked cotton; the defoliation time; the moisture content; the force of the cotton separating from cotton boll shell; the tearing force of the cotton itself
