| dc.description | The mechanical harvesting has been experimenting great technological evolution, in search of minimizing the losses that they can be avoided partially, being taken some tuning attentions. The objective of this work was to determine the losses of grain in the moment of the harvest in function of velocities, the reel of the harvester. An experiment was performed in the Abadiânia - Goiás, following a completely randomized design, factorial scheme 4x4, four-speed operation Vo1 = 2.6 km h-1, Vo2 = 3.3 km h-1, Vo3 = 5.0 km h-1 and Vo4 = 6.4 km h-1 and four speeds of the reel, 9%, 16%, 23% and 29% higher than the speed of the machine, with three replications. Were determined to cut losses of the platform, internal mechanisms and total harvest. Seeds were harvested with moisture of 18% w.b. The results were submitted to analysis of variance at 5% probability and operated using the correspondence analysis (CA). The results concluded: i) the analyzed losses are close of the acceptable limit, ii) the interaction between the operation speed and of the reel interferes on the losses provoked by the court platform, and iii) the analysis for correspondence allowed to analyze the relation between the operation speed and of the reel of the harvesters, in the determination of the losses of grains. | en-US |
| dc.description | A colheita mecanizada tem experimentado grande evolução tecnológica, em busca de minimizar as perdas que podem ser parcialmente evitadas, tomando-se alguns cuidados de regulagem. O objetivo deste trabalho foi determinar as perdas de grãos no momento da colheita em função das velocidades de deslocamento e do molinete. Foi instalado um experimento em Abadiânia, Goiás, seguindo o delineamento inteiramente casualizado, em esquema fatorial 4x4, com três repetições. Os tratamentos consistiram de quatro velocidades de operação (Vo1= 2,6 km h-1, Vo2= 3,3 km h-1, Vo3= 5,0 km h-1 e Vo4= 6,4 km h-1) e quatro velocidades do molinete, relativamente à velocidade da máquina (9%, 16%, 23% e 29% superior à velocidade da máquina). Foram determinadas as perdas da plataforma de corte, mecanismos internos e o total da colheita. Os grãos foram colhidos com umidade de 18% b.u. Os dados foram submetidos à análise de variância e explorados utilizando-se a análise de correspondência (AC). Os resultados permitiram concluir: i) as perdas analisadas estiveram próximas do limite aceitável; ii) a interação entre as velocidades de operação e do molinete interfere nas perdas provocadas pela plataforma de corte; e iii) a análise de correspondência possibilita uma análise da relação entre as velocidades de operação e do molinete da colhedora sobre as perdas de grãos na colheita.Grain losses in the mechanized harvest of upland rice asa function of speed displacement and reelAbstractThe mechanical harvesting has been experimenting great technological evolution, in search ofminimizing the losses that they can be avoided partially, being taken some tuning attentions.
