2.Design and Discussion on Seed Discharger with Inside Feeding Seed Vertical Disc of Fine Seeder
3.Application of many different size of seeds from small one to large with one seeder. One touch operation is possible to make correct distance and scattering seeds.
4.To improve the metering performance of the horizontal plate precision meter for corn, some key factors of the metering performance were determined. Calculation methods of the metering performance indexes by GB6973 86, ?Single(Precision) Seeder Experimental Method,? and the statistic program developed by the Lab Windows CVI software were applied to calculate different performance indexes;
5.In this article, several evaluation methods including performance test, user survey, tracking investigation and integrated evaluation are presented to evaluate the suitability of farm machinery through the exploration and practice on machine selection experiment of no-tillage seeder, and some questions in evaluation process are put forward and the corresponding solutions are also given.
