Title
(EN) GEOMETRY FOR CONTROLLING AIR VELOCITY IN A COMBINE HARVESTER
(FR) GÉOMÉTRIE POUR LA RÉGULATION DE LA VITESSE DE L'AIR DANS UNE MOISSONNEUSE BATTEUSE
Abstract
(EN)
A combine harvester has a threshing mechanism for threshing grain and cleaning apparatus for removing chaff from the threshed grain. The threshing mechanism includes a plurality of concaves and the cleaning apparatus includes and upper chaffer and a lower sieve. The combine harvester also has a blower having a rotating impeller and a blower housing. The blower housing has a first duct that directs a first airstream onto the upper chaffer and lower sieve, and a second duct that directs a second airstream along the underside of the concaves. An inlet to the second duct has a cross-sectional area that is larger than the cross-sectional area of an outlet of the second duct. The blower has a divider plate that separates high-velocity air from the impeller and directs the high-velocity air to either the first duct or the second duct.
(FR)
Une moissonneuse batteuse comprend un mécanisme de battage pour battre les grains et nettoyer l’appareil afin d’éliminer la balle de céréale des grains battus. Le mécanisme de battage comprend une pluralité de contre-batteurs et l’appareil de nettoyage comprend une grille supérieure et un tamis inférieur. La moissonneuse batteuse comprend aussi un ventilateur pourvu d’une turbine et d’un logement. Le logement du ventilateur présente un premier conduit qui dirige un premier flux d’air sur la grille supérieure et le tamis inférieur, et un second conduit qui dirige un second flux d’air le long du côté inférieur des contre-batteurs. Une entrée menant au second conduit présente une zone transversale qui est plus large que la zone transversale d’un orifice de sortie du second conduit. Le ventilateur a une plaque de séparation qui sépare l’air de vitesse élevée provenant de la turbine et le dirige vers le premier ou le second conduit.
