FIELD: agriculture.
SUBSTANCE: straw spreading device for a grain combine harvester comprises a pitched board installed behind a straw rack and a divider-dissector with a pipe located below it. The pipe has nozzles and is communicated with a source of excess air pressure. The pipe is equipped with a container in the form of a hemisphere, along the perimeter of which there are nozzles with sprayers. The sprayers have atomizers communicated by means of branch pipes with a dosing device. The sprayers are located under the nozzles. The divider-dissector is made in the form of a cut cone with an elliptical base with radial ribs, and is located above the container with nozzles.
EFFECT: uniform application of the solution to the straw surface, which improves soil fertility.
