Title A name given to the resource Desempenho de colhedoras semimontadas para a colheita direta de milho Performance of semi-mounted harvesters for corn harvesting Creator An entity primarily responsible for making the resource Carlos M. de Lima, José P. Molin, João C. de Araújo, Miguel A. I. T. del Pino Description An account of the resource O objetivo do trabalho foi adaptar procedimentos de ensaio existentes para colhedoras autopropelidas e avaliar o desempenho de colhedoras semimontadas, de uma e duas fileiras, operando com três velocidades de deslocamento em dois graus de umidade. Para tanto, foi desenvolvido um dispositivo de coleta do material efluente das máquinas, foram analisadas as perdas de plataforma, de separação e limpeza, de trilha e os parâmetros de qualidade: impureza, danos mecânicos dos grãos e falhas na germinação. O delineamento experimental foi em blocos casualizados, dispostos em esquema fatorial 2 x 3, com seis repetições. Não houve efeito dos tratamentos em relação às perdas na colhedora de uma fileira. Na colhedora de duas fileiras, houve efeito significativo nos fatores, em relação a todas as perdas, exceto as perdas de plataforma, apresentando melhores resultados com o menor grau de umidade (16%) e a maior velocidade de deslocamento (1,52 m s-1). Quanto aos indicadores de qualidade, ambas as colhedoras apresentaram melhores resultados com o menor grau de umidade, na menor velocidade de deslocamento. Concluiu-se que o procedimento adotado foi efetivo para a avaliação do desempenho de colhedoras semimontadas de milho, e o sistema desenvolvido para a coleta de material é eficiente, porém é exigente em mão de obra.The objective of this work was to adapt existent testing procedures for self propelled harvesters and to evaluate semi-mounted commercial harvesters of one and two rows, operating at three forward speeds and two grain moistures. A device was designed and adapted to the machines to collect the material other than grain (MOG) and the indicators analyzed were header loss, separation and cleaning loss, and threshing loss and the quality indicators were: impurity, damage and germination failures. The experiment was conducted as a randomized blocks design disposed in factorial outline 2 x 3, with six replications. There was no effect of treatments related to the losses for the one row harvester. For the two rows harvester there was significant effect in the grain moisture and speed, in relation to all the losses, except to header losses, presenting better results with the lowest grain moisture (16%) and higher forward speed (1.52 m s-1). Related to quality indicators, both harvesters presented better results with the lowest grain moisture in the lowest speed. It was noticed that the procedure for evaluating semi-mounted corn harvesters and the device designed to collect the MOG are efficient but exigent on labor demand.
