Resumo: | The growing demand for energy that causes the increased traffic of agricultural machinery, larger and more robust, acts negatively on soil compaction, directly and indirectly affecting crop productivity, as many changes in soil physical attributes. As a potential technique to solve this problem has the chiseling, which promotes the disruption of these compacted layers, without causing the inversion of the soil, keeps the plant residues deposited on the surface, improves infiltration, the structure and porosity of the soil and thus facilitates erosion control. However this operation has a high demand for traction. Seeking a more efficient operation of scarification, ie, better utilization of energy, developed and evaluated a tool to break ground in layers simultaneously. For this purpose it was necessary to construct a Structure-Port Mobile Tools capable of performing experimental procedures resulting from the planned treatments. As a mobile source of power was used a Massey Ferguson tractor model MF 275 with 53 kW. The experiment was conducted in the Municipality of Capon Beautiful South, Rio Grande do Sul, in a clayey soil. As a general objective, we sought to answer the following questions: (i) is there any significant difference between chiseling in a single layer or more than one layer, considering the average horizontal force on the drawbar, the specific resistance and the average hourly fuel consumption as criteria for each level of speed? (Ii) how the deepening affects the average horizontal force in the drawbar? And (iii) acts as the advance on the soil area mobilized? Configurations were tested with chiseling of the soil in one, two and three layers, with variations in longitudinal distances between the tips of the spikes. The chiseling treatments in two concurrent 0,15 meters layers and longitudinal distance between the tip ends of 0,30 and 0,40 meters, with one in 0,10 meter of deepening and 0,30 meters advancing presented as the most promising. It was concluded at the end of this work, considering all the tested configurations, there are combinations of deepening, advancing and speed, which proved more efficient than chiseling a single layer. |

Como técnica potencial para solucionar este problema tem-se a escarificação, que promove o rompimento dessas camadas compactadas, sem ocasionar a inversão do solo, mantém os resíduos vegetais depositados na superfície, melhora a infiltração, a estrutura e a porosidade do solo e facilita assim o controle da erosão. Contudo esta operação apresenta elevada demanda de tração. Visando uma operação de escarificação mais eficiente, ou seja, com maior aproveitamento de energia, desenvolveu-se e avaliou-se uma ferramenta para o rompimento do solo em camadas, de forma simultânea. Para tanto foi necessária a construção de uma Estrutura Porta-Ferramentas Móvel, capaz de executar os procedimentos experimentais decorrentes dos tratamentos planejados. Como fonte móvel de potência foi utilizado um trator marca Massey Ferguson, Modelo MF 275 com 72 CV (53 kW) de potência. O experimento foi conduzido no Município de Capão Bonito do Sul, Rio Grande do Sul, em um solo de textura muito argilosa. Como objetivo geral, buscou-se responder às seguintes perguntas: (i) existe alguma diferença significativa entre a escarificação em única camada ou em mais de uma camada, considerando a força horizontal média na barra de tração, a resistência específica e o consumo horário médio de combustível como critérios, para cada nível de velocidade? ; (ii) de que forma influi o aprofundamento (espessura das camadas) na força horizontal média na barra de tração? ; e (iii) como atua o avanço (distância longitudinal entre as ponteiras das hastes), sobre a área de solo mobilizada? Foram testadas configurações com escarificação do solo em uma, duas e três camadas, com variações nas distâncias longitudinais entre as pontas das ponteiras. Os tratamentos com escarificação em duas camadas simultâneas de quinze centímetros e distância longitudinal entre as pontas das ponteiras tanto de trinta quanto de quarenta centímetros, juntamente com aquele com aprofundamento de dez e avanço de trinta centímetros apresentaram-se como mais promissores. Concluiu-se ao final deste trabalho, considerando todas as configurações testadas, que existem combinações de aprofundamento, avanço e velocidade, que revelaram-se mais eficientes que a escarificação em camada única.Universidade Federal de Santa MariaBREngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia AgrícolaAlonço, Airton dos Santoshttp://lattes.cnpq.br/9734276321240323Schlosser, José Fernandohttp://lattes.cnpq.br/0575023987760421Durigon, Regeshttp://lattes.cnpq.br/4039409915626426Eltz, Flavio Luiz Folettohttp://lattes.cnpq.br/2238828304382975Gassen, José Renê Freitas2013-06-192013-06-192011-10-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfapplication/pdfGASSEN, José Renê Freitas.
