Variable straw and chaff distribution arrangement

A variable straw and chaff distribution arrangement in an agricultural harvesting machine having means for separating straw, an air sieve device for separating chaff, and a straw chopping device having an outlet, the arrangement including:

• a wall element arranged vertically between the straw chopping device and the air sieve device;
• an articulated lever combination;
• means associated with the articulated lever combination for selectively moving the same;
• first and second distribution blowers, each blower having a material inlet opening and being connected to the articulated lever combination, said distribution blowers being adjustable between at least two different positions by operation of the articulated lever combination, wherein the outlet of the straw chopping device lies in a plane of the material inlet opening of the distribution blowers;
• guide means for supplying chaff radially to the rotary blower;
• a collecting spiral conveyor located generally below the wall element;
• a paddle conveyor operatively connected with the collecting spiral conveyor;
• a wedge-shaped guide element operatively connected with the paddle conveyor by the guide means and arranged centrally between the distribution blowers;
• and
• wherein the wall element catches chaff and directs it to the collecting spiral conveyor, said collecting spiral conveyor then directs the chaff to the paddle conveyor which then directs it to the guide element via the guide means and wherein the guide element divides the chaff between the distribution blowers.

A variable straw and chaff distribution arrangement in an agricultural harvesting machine having means for separating straw, an air sieve device for separating chaff, and a straw chopping device having an outlet, the arrangement including:

• a rotary blower having a material inlet opening;
• an articulated lever combination for adjusting the rotary blower between first and second working positions operatively connected to the rotary blower;
• means associated with the articulated lever combination for selectively moving the same;
• variable guide means for supplying chaff radially to the rotary blower;
• and
• a pivotable flap which is movable between a feeding position for feeding straw to the straw chopping device when the rotary blower is in the first working position and a blocking position for blocking flow of straw to the straw chopping device when the rotary blower is in the second working position.
