Cassette Loading Units for Hanging Devices of Breeding Seeders

Abstract

The cassette loading device of breeding seeders is designed for sequential movement of cassettes with seed material to the sowing apparatus of the seeder. (Research purpose) The research purpose is reviewing of breeding seeders with a cassette loading unit for sowing machines and analyzing the technical solutions used in the devices. (Materials and methods) Conducted a review of cassette seeders for sowing various crops in breeding and primary seed production in order to find effective technical solutions. We compared different design solutions of cassette loading devices and chose the most rational design elements. (Results and discussion) The direction of improvement towards the robotization of a cassette device for loading breeding seeders was revealed, which increases the productivity of this auxiliary operation and reduces the use of manual labor. A classification of cassette loading devices used on breeding seeders was proposed. Formulated the technical task of developing a new device design. (Conclusions) We analyzed domestic and foreign technical solutions of cassette loading devices for sowing machines of breeding seeders, determined their technical and technological features. It was established that the improvement of the cassette device for loading breeding seeders, which increases the productivity of this auxiliary operation and reduces the use of manual labor, should be implemented in the direction of robotization of the process of operation of the cassette loading device. It was stated that in order to create a robotic cassette loading device, it is necessary to develop a manipulator controlled by a programmable electronic controller and a control system that ensures: moving cassettes along a guide (carrier) plate and feeding them to the holes for unloading seed material into the loading cylinders of sowing machines; sequential feeding of cassette blocks to a cassette table (in the working area); synchronization of the seeding machines with the operation of the loading device.
