Chaff-distributing appliance for combine harvesters

摘要

A chaff-distributing appliance for combine harvesters has rotating blades. In order, along with a simple and rapid adaptation to the straw flow, to allow simple and rapid access to the screen boxes, two oppositely driven rotors with at least two shovel-like blades are mounted next to one another rotatably about mutually parallel axes in a supporting frame provided with a rear cover plate. The frame is guided displaceably on two lateral bearers (7) and can be locked. The lower ends of the bearers (7) are mounted pivotably in side walls of the housing or lateral bearers of the combine harvester (1) below the lower screen box (4). The upper ends of the bearers (7) can be fixed at the height of the upper screen box (3) on the side walls or bearers of the combine harvester in different pivoting positions (Figure 1). <IMAGE>
