Avaliação de perdas na colheita mecanizada de trigo

Abstract

The wheat crop has emerged as an important winter cereal and occupy large tracts of land, mainly in the south of Brazil the winter crop. During harvest many factors mean that there is grain losses, reflecting the productivity of crops. Some factors have minimized through your settings in harvester own effects. On the other hand, there are situations, such as tilt of the machine, which accentuate the losses, especially in cleaning and separation systems without automatic leveling. Thus, the present study aimed to evaluate the losses of grain in three different speeds and in three conditions inclination of the combine without automatic leveling sieves. It was concluded that increasing the speed of displacement and the inclination of the harvester losses increased. However, in places most likely to speed 4 km h -1 had values similar to areas with less loss slope.
