为了提高玉米播种的合格率,降低单粒率、重播率和和漏播率,对玉米播种机的排种器结构进行了优化设计,并采用图像白噪声处理,提出了圆盘精密排种器的结构优化方法. 在排种器圆盘倾斜角度的设计优化过程中,为了提高玉米种子尺寸结构图像信号采集的准确度,引入了一种白噪声信号处理的倾斜角度和理论计算值进行结合,优化了排种器的结构. 为了测试该方法的有效性和可靠性,对排种器的播种性能进行了测试,通过测试发现,改进后的排种器在单粒率、重播率和漏播率性能上都优于普通方法设计的排种器,提高了玉米播种机的播种效果.

In order to improve the qualified rate of corn seed, decrease the rate of single grain rate, replay and and so-wing rate, leakage of corn seeder metering device structure has been optimized design, white noise and using image pro-cessing methods, the proposed plate precision metering device structure optimization method.In the design of the metering device disk tilt angle optimization process, in order to enhance the accuracy of maize seed size structure image signal ac-quisition, the introduction of a white noise signal processing angle is combined with the theoretical calculation value, op-timization of the structure.In order to test the validity and reliability of this method on the planting of performance were tested, by testing found that the improved seed metering device in a single grain rate, and leakage and sowing HFM can replay rate than the general design method of high precision metering device, improve the effect of planting corn seeder.
