Influence technical and technological factors on efficiency combine harvesters

Found that scientists were ignored research efficiency technical features inherent in design combines, including: engine load, bandwidth, energy performance and their effect on the mechanical losses grain combine. Established that indicators of physical, parametric reliability, productivity medley, agrobiological condition affecting the grain weight heavily on the capacity of the combine and, accordingly, its performance and loss of grain on the threshing-separating device. Analytical dependence speed of the combine in comfield of loading and parametric engine reliability, systems and mechanisms of the machine. Developed an integrated method for determining the capacity and the influence of non-uniformity and yield fluctuations in area fields on it. Dependence performance combine harvester on the relative values of mechanical losses in threshing-separating device. Determined significance mechanical losses of grain on efficiency.
