Design on the Pre Filling Seed-clearing Institution of Insert-metering System for Soybean Sub-district Seeder
摘要
Abstract
In order to satisfy the requirements of soybean sub-district seeding without hybrid and other convenient,solve the bigger idle running and incomplete seed-clearing,the pre filling seed-clearing institution form of curved arc for the insert-metering device was designed.The theoretical analysis was used to determine the basic parameters of the arc rack and the decreasing coefficient for the fore and aft-tooth addendum,and the results of the gear mesh with arc rack simulation based on ADAMS software showed that the design met the requirements.The soybean Suinong 26 was selected as experimental material,performance comparisons test results of the suction drum-type seed metering system before and after improvement showed that,the idle running of the improved insert-metering system was within 0.42 m and quickly insertion and extraction within 3.33 s to accomplish another without hybrid which met the design requirements,laid a solid foundation for the development of the series of soybean breeding seeder.关键词
