Automation of a seed on tray seeder machine

Abstract:

The machine aims to fully automate the process to sow seeds. Generally, these types of activities are semi-automatic, however, the proposed solution aims to improve the efficiency of the process and the reduction of human intervention. It mainly has a mechanical part whose technique is based on a four-bar system, as for the electronic and control part it is commanded by an Arduino card. The mechanical design was carried out using CAD software, and based on the results obtained by various flexural and deformation analysis software, it was possible to select the materials and the motor to be used. The process works from operational requirements such as: transmitting the linear movement of the components, placing and aligning the transport mechanism, transmitting enough power to drill and place the seeds and finally controlling the air flow. As a result, this automated method represents 25% more efficiency and a 50% reduction in personnel compared to the manual method. In the same way, a filling of 87% of cavities for seeds was obtained, this being its highest efficiency with a pressure in the range of 0.2 to 0.3 MPa in the pressure ejector.
