RESEARCH DEVELOPMENT ON THE KEY TECHNOLOGY OF WHEAT SINGLE SEED ROBOT

摘要

The wheat precision seeding technology is an effective way to increase the production of wheat. The lack of proper wheat seeder is the main obstacles to promote the application of the technology. A wheat precision seeding robot was designed in this paper. The robot consisted of the wheat precise seeding mechanism and the motion platform. The seeding mechanism, the movement platform, the sensor system and the control system were emphatically discussed. Through the experiment, the optimal parameters of the size of suction-hole was 2.55mm, the seed plate speed was 22.3r/m and the air chamber pressure was 2.46kPa. The seeding qualified rate of this robot had achieved 94%.
