Concept and performance of an autonomous precision seeder for grain crops Optimization of seed embedding into the soil

A precise and even grain seed embedding into the soil has a big potential to enhance crop growth and therefore increase yield and decrease chemical inputs. The aim of the project is to optimise grain seed embedding and distribution with a precision grain seeder combined with an autonomous machine. Commercial industrial components for seeding and grain singling were used to allow precision seeding of grains. A small catch crop seeder was used to function as a seed storage and conveying system. The singulation performance and quality of each dosing device were intensively tested. The results showed a very high cell filling rate of more than 90 % and very high spacing evenness for most rpm. Electric linear motors are used for each row to adjust the seeding depth and recompactioning independently. The autonomous robot functioning as a carrier with the necessary field navigation opportunities. © 2022, VDI Verlag GMBH. All rights reserved.
