为设计开发三倍体西瓜种子破壳机排种器,通过实验对三倍体西瓜种子的主要物理特性进行了测定。实验采用3种无籽西瓜种子黑牛、蜜红和花皮,含水率分别为7.11%,6.98%,6.69%,选用种子物理特性标准测定方法进行了测定和应用分析。实验结果得出无籽西瓜种子的长度、宽度、厚度、千粒质量、真密度、休止角与木板、涂漆铁板、塑料板和玻璃的静滑动摩擦系数的变化范围。研究结果填补了无籽西瓜种子物理特性空白,并为开发无籽西瓜种子破壳机排种器的设计提供了理论计算依据。

In order to develop a metering device for triploid watermelon seeds broken shell machine,the key physical properties of triploid watermelon seed were measured.Watermelon seeds of three varieties,Heiniu,Mihong and Huapi,at the moisture content of 13.0,11.2 10.6%（w.b.）,were selected to study the physical properties using standard methods,respectively.Experimental results obtained the physical properties＇ parameters,length,width,thickness,repose angles and static coefficient of friction of the three varieties＇ seeds.It is concluded that the st...
