摘要:
针对花生排种过程中存在的机械破损问题，以花生品种四粒红不同条件下的初始破碎力为指标，开展花生三轴方向上的起始破碎力测定试验。采用全组合试验方法，以压缩速度、含水率为因素，分析了花生种子在不同含水率和不同压缩速度条件下x、y、z三轴方向起始破碎力的变化规律。结果表明：当浸泡温度20 ℃，浸泡时长为3 h，花生含水率达154%时，起始破碎力在三轴方向均最大；在不同压缩速度下，花生种子起始破碎力沿x轴方向最大，沿z轴方向最小，分别平均为3586 N、2235 N；同一压缩速度下，花生种子起始破碎力随含水率变化呈先增大后减小的趋势。该研究成果为进一步研究花生种子的力学特性、损伤机理及播种机的研发提供依据。
Abstract:
In order to solve the problem of mechanical breakage in peanut seed metering, the initial crushing force of Silihong was taken as an index to test in triaxial direction. Taking compression speed and moisture content as factors, the variation of initial crushing force of peanut seeds in the directions of x, y and z under different water content and compression speed was onalyzed by using the whole combination test method. The results showed that when the soaking time was 3 h, the soaking temperature was 20 ℃, and the moisture content was 154%, the initial crushing force of peanut seeds was the largest in triaxial direction. Under different compression speed, the initial crushing force of peanut seeds was the largest along x axis, and z axis the smallest along, with on average of 3586 N and 2235 N, respectively. At the same compression rate, the initial crushing force of peanut seeds increased first and then decreased. The results will be helpful for further study on mechanical properties, damage mechanism and the research and development of seeding machine.
