Resumo: | In the cassava production the conventional tillage, characterized by soil preparation with intensive mobilization, is commonly used. However, when this practice results in the maintenance of small quantities of straw on the soil surface, the erosion becomes imminent, and it is exacerbated by the spacing and slow initial development of this culture, especially until four months after planting. An alternative is the no-tillage system, a type of conservation tillage, in which only the owing/planting furrow is prepared for the deployment of culture, and is widely used in soybean, corn, wheat, beans, and others crops. For cassava, the adoption of this system has raised many questions on the basis of the soil physical properties recommended, according to which the crop requires well-drained and loose soils to allow the proper root development, where the carbohydrates produced by the plant are stored. It is believed that the deployment of a larger soil area in furrow may facilitate the proper development of cassava in no-tillage system and promote the soil protection due the maintenance of straw on the surface. In this context, the objective is improve the furrow opener device of cassava planters using the precepts of the agricultural machinery development process, with the intent of provide the cultivation of cassava in no-tillage system. For the furrow opener development it were implemented the informational, preliminary and detailed design phases of the product development process.

Quando esta prática resulta na manutenção de pequenas quantidades de palha sobre o solo, o problema da erosão se torna eminente e é agravado pelo espaçamento entre linhas e o lento desenvolvimento inicial desta cultura, principalmente até os quatro meses após o plantio. Uma alternativa é o sistema plantio direto, em que apenas o sulco de semeadura/plantio é preparado durante a implantação da cultura, e é largamente utilizado nas culturas de soja, milho, trigo, feijão, entre outras. Para a mandioca, a adoção deste sistema tem gerado muitas dúvidas em função das condições físicas do solo recomendadas, segundo as quais a cultura requer solos bem drenados e soltos para possibilitar o adequado desenvolvimento das raízes. Acredita-se que a mobilização de uma maior área de solo no sulco de plantio possa viabilizar o adequado desenvolvimento da mandioca em sistema plantio direto e favorecer a proteção do solo pela manutenção da palha sobre superfície. Nesse contexto, objetivou-se aperfeiçoar o mecanismo sulcador de plantadoras de mandioca utilizando os preceitos do processo de desenvolvimento de máquinas agrícolas, com o intento de viabilizar o cultivo de mandioca em sistema plantio direto. Para o desenvolvimento do mecanismo foram executadas as fases de projeto informacional, preliminar e detalhado. Formularam-se, para a função de preparar o sulco de plantio, 31 necessidades de clientes que foram desdobradas em 30 requisitos de clientes e posteriormente em 27 requisitos de projeto. A partir destes requisitos e das soluções disponíveis em outras máquinas e implementos, selecionou-se a haste sulcadora alada como potencial solução. Desta forma, realizou-se um estudo de leiautes que culminou na construção de protótipos com diferentes geometrias para testes, experimentação com a cultura da mandioca e ensaio de esforços. A utilização do modelo de referência para o processo de desenvolvimento de máquinas agrícolas permitiu o desenvolvimento de uma haste sulcadora alada de baixo custo, pequeno número de componentes, processo de fabricação simples e bom funcionamento. A produtividade obtida com a cultura da mandioca em preparo convencional e sistema plantio direto foi semelhante, evidenciando que esta técnica pode ser utilizada para o cultivo sem comprometer a produtividade e ainda melhorar a sustentabilidade do sistema.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaHastePreparo do soloProjeto de máquinasWinged tinesStrip tillageMachinery project processCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLAAperfeiçoamento de um mecanismo sulcador para plantio direto de mandiocaImprovement of the furrow opener device of cassava planters to no-tillageinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisHeldwein, Arno Bernardohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4788078U3Romano, Leonardo Nabaeshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4728860D9Reichert, José Miguelhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4787840U9Batista, Vilson Joãohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4788482Z8Boller, WalterBOLLER, W.http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4706231A6Fey, Emerson5003000000084005003003005003003002075a668-626c-446c-8b01-37ca432bd67f84d62de8-07c8-44cc-ad32-b302f4d961dc5d68eac2-00c3-4bee-a734-47b48eeae41cce667b2e-016e-44f9-b53f-e28d71d4359d6d965451-f120-4310-9a3d-0aa7fd9f140fb6fada00-f1fa-4143-bbb5-34c4c3ea45b7info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALFEY, EMERSON.pdfTese de Doutoradoapplication/pdf1580137http://repositorio.ufsm.br/bitstream/1/3579/1/FEY%2c%20EMERSON.pdf7dac4378e2c17836c83d69580c349fc2MD51TEXTFEY, EMERSON.pdf.txtFEY, EMERSON.pdf.txtExtracted texttext/plain113286http://repositorio.ufsm.br/bitstream/1/3579/2/FEY%2c%20EMERSON.pdf.txta3271fa4177e470ab71822f6e74bc7b2MD52THUMBNAILFEY, EMERSON.pdf.jpgFEY, EMERSON.pdf.jpgIM Thumbnailimage/jpeg4887http://repositorio.ufsm.br/bitstream/1/3579/3/FEY%2c%20EMERSON.pdf.jpg95dc5e606b1377db620be8290c7d6c9eMD531/35792017-08-28 15:40:22.957oai:repositorio.ufsm.br:1/3579Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2017-08-28T18:40:22Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
