Análise de falhas de um sistema técnico agrícola para implementação sulco-camalhão

Abstract

The advance in the agribusiness of Brazil is of great influence for the development of the country. The increase in grain yield, the control of spontaneous plants and the diversification of income are factors that promote searches for crop alternatives. For this, the incorporation of rainfed agriculture, such as soybean and corn, in rotation with the irrigated rice production system in lowland areas, becomes an opportunity for improvement. However, the lack of implements that fully meet this function creates greater difficulties for farmers. As a result, agricultural equipment was developed through empirical knowledge and "trial and error" in order to facilitate the implementation of the furrow system. This system helps soil drainage during high rainfall levels and makes it possible to flood irrigation in rainfed agriculture in periods of drought, reducing the damages that these weathers can cause. Thus, the present work aims to identify potential failures and to analyze the risks of an agricultural prototype subsystem for the furrow-ridge implementation. For this, a survey was carried out in catalogs and online platforms in order to know agricultural implements available in the market and, also, a search of antecedents in the Questel Orbit commercial software to identify the registered products. In addition, the FMEA design tool was used in the main components of the chosen subsystem, indicating the parameters of gravity, probability of occurrence and detection, in which it was possible to analyze the possible failure modes and their effects together with proposals for improvements to the subsystem. Both the research in catalogs and online platforms, as well as the search carried out by the software, made possible the knowledge of different systems for agricultural use, however, none that was effectively similar to the one proposed in the work. With the analysis of the main components of the system, the disc blades was the one that presented the greatest risk, since its failure prevents the system from operating correctly.
