棉秆拉拔力影响因素的分析及试验
|
摘要
棉秆拉拔力是设计棉花拔秆机的一个重要指标参数,而棉秆拉拔力的测定将受到其它因素的影响,为了探讨拔秆位移、棉秆直径、土壤含水率、土壤紧实度、起拔角度等因素对棉秆拉拔力的影响,笔者设计了棉秆拉拔力的测定试验方案并进行了棉秆拉拔力的测定试验。试验结果表明:棉秆直径与起拔力呈正相关回归关系,相关系数为0.861。土壤含水率越高,起拔力越小;土壤紧实度越大,起拔力越大。起拔角度对起拔力具有一定的影响,拉拔力与水平呈30°~45°时,起拔力较小。
Cotton stalk drawing force is an important parameter for cotton drawing machine, and the cotton stalk drawing force determination will consider other factors, in order to study the influence of factors such as pull-out displacement, cotton stalk diameter, rate of soil moisture,soil compactness on the stalk drawing force, writer designs the cotton stalk drawing force measurement test scheme and doing the determination of the cotton stalk drawing force test, for development of pull institutions of cotton stalk harvesting machinery to provide the reference. The experimental results indicated that the cotton stalk diameter and the pull-out force between is positively related to the regression relation, correlation coefficient is 0.861. The higher the soil moisture content, the smaller the pull-out force; the bigger the soil compactness, the bigger the pull-out force. The draft angle had a certain amount of influence on the stalk pull-out force, when the draft angle was 30° ~45°, the pull-out force is smaller.
