Abstract: 【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 effects of water content and maize seed varieties on the stacking angle.
