Sistema mecânico de carregamento de frutas cítricas em pomares.

Abstract in Portuguese
A determinação em se desenvolver um equipamento adequado à realidade da citricultura brasileira, para a mecanização do carregamento de frutas cítricas nos pomares das fazendas, surgiu em consequência da gradativa escassez de mão de obra para o carregamento manual. A viabilidade econômica do equipamento e as constatações da pesquisa inicial, foram fatores determinantes nas decisões técnico-construtivas adotadas durante o seu desenvolvimento. O sistema projetado, constitui-se de uma estrutura metálica horizontal articulada em dois mancais sobre uma estrutura vertical que é presa à carroceria de um caminhão ou carreta. As caixas com 600 (seiscentos) quilos de fruta posicionadas embaixo do equipamento, são elevadas por um conjunto de cabos de aço e correntes do chão ao nível inferior da estrutura basculante. A seguir este conjunto gira em torno do eixo dos mancais, derrubando as frutas através de uma calha para dentro do veículo de transporte. Ao término da queda das frutas, a caixa é devolvida ao solo, ficando o sistema disponível para outro ciclo.

Abstract in English
The need of developing an equipment in order to mecanize citrus fruits in the country farms, became from the lack of hand labor to make manual loading from crop to crop. The equipment economical viability and initial research considerations, were determinant factors in the technical and constructive decisions taken during its development. The system projected and designed is composed by a horizontal metal structure hinged in a vertical structure held on a truck or a tow truck frame and body. The fruit boxes weighting 600 (six hundred) kilograms are placed underneath the equipment. Thereafter They are lifted by a system of steel cables and chains, from ground to the bottom level of a seesawing structure. The whole piece turns around its axis dropping the fruits in a gutter to inside the transport vehicle. After this operation the box is lowered back to its original position, and the system is ready to recycle.
