Experimental study on the relationship between the seeding rate and seeding performance of the seed metering device

摘要

This paper using the STB-700 tester and the three kinds of soybean seed metering device speed and the relationship between the seeding effect experiment, explore the impact of the metering device speed on the working performance of the seed metering device. With inclined disk scoop metering device as an example, through the study found that the rotation speed of the metering device effect on seeding performance and the law. And use the FMINBND function to solve the MATLAB to determine the minimum replay of the seeding rate value is 44.05 r/min, the minimum value of the leakage sowing rate for 40.71r/min, 39.65r/min minimum spacing variation coefficient. In order to find the best set of declined disc scoop type soybean seed metering device installed in the soybean on no tillage planter speed range is 4 ～ 5km/h, increased soybean planter installation of the metering device in the Huang-huai-hai region adaptability.
