The design is based on the development trends and seeder, interoperability and adaptability ina constantly improving the structure and operation of flexible simple principles designed to simultaneously plish a small planting fertilization work multifunctional sophisticated seeder. This structural advantages so that they can adapt toa variety of fields planting. Applicable to all sizes of land; Whether plains or hills; Whether hard soil or loose soil. We can select the planting machine according to the different needs of users. By regulating platoon of vehicles and plow can easily sow wheat. This example focuses on the design seeder platoon of vehicles, fertilization devices, trenching vehicles structure. Key words : precision planting seeder planting fertilization 充值下载即送 CAD 图纸, QQ 36396305 III 目录摘要............................................................................................................................
