Desenvolvimento do conceito de uma semeadora de precisão autônoma

Abstract

Precision agriculture is already a reality in Brazil and in the world, so companies are increasingly developing machines and equipment that perform more precise work and with more technology. Soybean is the main agricultural crop in our country, and an autonomous precision seeder line will ensure that the work of planting the seed in the field is carried out with as little human interference as possible, only for eventual calibrations, using technologies that allow its use 24 hours a day, with fuels that do not pollute the environment. The designed equipment must be compact and practical to be used, which allows its use by small, medium and large agricultural producers, varying only the amount of equipment that will work in the crops. The development of this concept was based on the methodology proposed by Pahl et al. (2005), divided into 3 main phases: task clarification that presents the initial planning for the development of the concept, ideas were systematically researched, and the most promising ones were selected. The second phase, called conceptual design, in which the preliminary solution is defined, and the implementation takes place for the evaluation of the operating structure. All of this was based on the inclusion of factors such as materials to be used, approximate sizing, and technological resource considerations. The third and final phase, called the concept structure, presents the final layout, together with the structuring of the concept, in addition to essential characteristics such as following up on the project, allowing the presentation of the concept of a product with possibilities of progressing to a definitive design, prototyping and large-scale manufacturing. This study made it possible to document and support the concept of a viable equipment, with characteristics that are already part of the reality in world agriculture, which aims to improve the quality of work of the farmer, in addition to enabling the generation of more food for humanity.
