摘　　要：针对玉米育种试验过程中出苗率低、现有条播排种器播种不均匀无法满足试验要求等问题,在现有条播排种器基础上进行优化设计;通过在锥体上增加均格的方式来提高排种均匀性,分析了锥体倾斜角度、均格数量和锥体转速对均格式锥体排种器排种性能的影响,并进行仿真试验。试验结果表明:在锥体转速为0.8 rad/s、锥体倾斜角为48.1°、锥体均格数量为30个时,排种性能最优,排种均匀性变异系数降为20.295%;影响排种均匀性的主次因素为锥体均格数量>锥体倾角>锥体转速。田间试验表明:对比无均格锥体排种器,优化后的均格式锥体排种器排种均匀性变异系数降低18.73%,排种器的排种性能显著提升,能够满足小区试验要求。Aiming at the problem of low seedling rate during maize breeding test and uneven seeding of existing striped seed drainers,optimized the design on the basis of existing striped planter.Increase the homogeneity of the row by adding the homogeneous lattice to the cone.The influence of tilt angle,number of average lattice and speed of the cone on the planting performance of the average format cone was analyzed and simulated.The experimental results show that when the speed of the cone is 0.8 rad/s,the inclination angle of the cone is 48.1°,and the average number of cone cells is 30,the optimal performance of the seed arrangement,the variation coefficient of the homogeneity of the cone arrangement decreases to 20.295%.Field experiments show that the uniformity variation coefficient of the homogeneous vertebral platter is reduced by 18.73%,and the platting performance of the platter is significantly improved,which can meet the test requirements of the district.
