Analysis and Experiment on the Performance of Spoon Wheel Cotton Seed Metering Device
摘要
Abstract
In order to study the effect of the seed metering device on the seed metering performance under different motion characteristic parameters,the simulation model of the scoop-wheel seed metering device was established,and the virtual test of the working process of the seed metering device under different rotational speeds and inclination angles was carried out by using EDEM software,and analyzed the movement trajectory of a single cotton seed in the seed meter and the change trend of the grain population force over time.The simulation results showed that when the rotation speed of the seed metering device was 40 r/min and the inclination angle was 15°,the seed metering device had relatively best working performance.The qualified rate was 98.15％,re-seeding rate was 1.85％,missed-seeding rate was 0.The bench test of the seed metering device was carried out with the JPS-12 performance testing platform.In the bench test,when the speed of the seed metering device was 40 r/min and the inclination angle was 15°,the variation coefficient of the distance be-tween the cotton grains was 0.034,and the seeding uniformity was higher,indicating that the performance of the seed me-tering device was better,and the seed metering effect of the bench test was good.The re-seeding rate and missed-seeding rate of the field test were improved compared with the results of the test bench,but still met the qualified rate of more than 90％,and the variation coefficient of grain spacing was less than 10％,which could be used for field sowing.关键词
