基于崩塌法的玉米堆积角测定仪设计与试验

Design and testing of an instrument for determining the angle of maize accumulation based on the collapse method

【目的】为便于准确测定玉米种子堆积角,设计了1种通过无线遥控器控制的双层堆积角测定仪。【方法】通过无线遥控器控制测定仪活动板的开合,玉米籽粒群自由下落形成堆积角,利用角度尺直接测量实验时的堆积角。【结果】干燥前良玉88品种玉米堆积角要明显大于先玉335、郑单985,干燥后3个玉米品种籽粒堆积角呈减小趋势,可见玉米堆积角随含水率的增加而减小,且不同品种间存在差异。【结论】试验结果验证了设计仪器的可靠性,并揭示了含水率和玉米种子品种对堆积角的影响。

【Objective】To facilitate the accurate determination of the accumulation angle of maize seeds,a double-layer accumulation angle tester controlled by a wireless remote control has been developed.【Method】The opening and closing of the movable plate of the tester was controlled by a wireless remote control,and the group of maize seeds fell freely to form the stacking angle,and the stacking angle during the experiment was measured directly by using an angle ruler.【Result】Before drying Liangyu 88 varieties of maize stacking angle is significantly larger than the first Yu 335,Zhengdan 985,after drying the three maize varieties of grain stacking angle was a trend of reduction,it can be seen that the maize stacking angle with the increase in moisture content and reduce,and there are differences between different varieties.【Conclusion】The experimental results verified the reliability of the designed apparatus and revealed the ef fects of water content and maize seed varieties on the stacking angle.
