Research and 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 obstacle to promote the application of the technology. A wheat precision seeding robot is designed in this paper. The robot consists of a wheat precise seeding mechanism and a motion platform. The seeding mechanism, the movement platform, the sensor system and the control system are mainly discussed. Through the experiment, some optimized results are found as that the size of suction-hole is 2.55mm, the seed plate speed is 22.3r/m and the air chamber pressure is 2.46kPa. The qualified seeding rate of this robot can achieve 94%.
