“…O custo de aquisição, o qual é uma necessidade de grande importância para o agricultor familiar [15,[22][23] depende do custo de fabricação; para a confecção do protótipo 1 o valor total foi de R$ 96,50, sendo R$ 6,50 com materiais e o restante com serviços de usinagem. Ao testar o protótipo 2 (Figura 5), constatou-se que a manutenção do formato circular do sistema cortador permitiu um corte regular ao longo da espiga separando os grãos do sabugo uniformemente, deixando-os inteiros; apenas os grãos imaturos da ponta da espiga não foram debulhados, porém, esses grãos são considerados defeituosos para Instrução Normativa [24].…”

____________________________________________________________________________________________________________ RESUMONas propriedades familiares vem crescendo a implantação de pequenas agroindústrias de processamento de produtos oriundos do próprio setor. O milho verde em conserva é um exemplo de produto comercializado pelos produtores familiares, porém, necessita ser debulhado, sendo essa tarefa normalmente executada de forma manual com auxílio de ferramentas domésticas. Os debulhadores de milho verde comercializados atualmente são para produção em alta escala, tornando-se equipamentos inacessíveis aos agricultores familiares. Nesse contexto, este estudo teve a finalidade de desenvolver um debulhador de milho verde para esses produtores. A metodologia utilizada fundamenta-se no Modelo de Fases, empregado com êxito no projeto de máquinas agrícolas, o qual se divide em quatro etapas: projeto informacional, projeto conceitual, projeto preliminar e projeto detalhado. Como resultado da aplicação da metodologia, obtiveram-se três concepções e três protótipos de debulhadores de milho verde. Após a realização dos ensaios, o protótipo 3 foi determinado o ideal para atender às necessidades dos agricultores familiares.Palavras-chave: Máquinas agrícolas. Desenvolvimento de produto. ____________________________________________________________________________________________________________ IntroduçãoO Brasil é atualmente o terceiro maior produtor de milho do mundo. No censo agropecuário de 2017 foram identificadas 1.628.805 propriedades produtoras de milho, contando com uma produção de 90.822.585,448 de toneladas [1]. A projeção é que a produção aumente, visto que a estimativa para a safra 2018/2019 é em torno de 97 milhões de toneladas [2].

Family farming in Brazil is responsible for the country's food security, ensuring most of the food consumed by Brazilians. However, the agricultural machinery and equipment industry has not been dedicated to providing innovations to this sector, focusing mainly on supplying large agribusiness properties with the most advanced technology equipment. Thus, the introduction of new technological solutions regarding agricultural machines for family farming is necessary. Considering the need to supply this branch of the Brazilian agricultural sector with new technologies, this study aimed to establish the design specifications of an autonomous electric vehicle that serves as a multifunction platform, which was primarily designed to remove weeds, mainly meeting the needs of family farmers. The product development methodology in its informational phase was applied to obtain and study these needs. As a result, 19 design specifications were established with their associated target values, allowing defining the physical and economic parameters that will be the basis for the development of the autonomous electric vehicle in its conceptual phase.

Given the real need for advances in studies such as the relationship of soil-machine dynamics, it is clear that there are almost no innovative systems developed to attend this demand. The design of agricultural machinery and equipment can be facilitated by having information and mechanisms that allow the prediction of the mechanized-set behavior in real work situation, especially regarding the traction effort demanded by the tractor, due to the energy demand of the equipment that interact directly with the soil. Obtaining this information usually requires high-cost imported laboratory equipment. Thus, the objective of this work was to obtain the design specifications for the development of a direct shear and soil pre-compaction analysis equipment with low manufacturing cost. The Phases Methodology was used to obtain the necessary parameters, in the informational phase of the desirable aspects for each design requirement. Through a step-by-step analysis, it was possible to obtain customers’ needs, together with the establishment of the desired criteria, and the design requirements for the new product development was generated. The use of the Phases Model allowed the transformation of customers’ requirements into the design requirements, enabling hierarchization by degree of importance and thus enabling the execution of future steps.
