Crop / Straw discharge

The main parts of the crop and straw discharge unit include:

1. Straw walkers: These are a series of rotating frames with metal fingers that shake the straw and chaff to separate it from the grain.

2. Straw chopper: This component cuts the straw into smaller pieces, making it easier to spread on the field as mulch.

3. Auger: The auger helps to move the crop material from the threshing and separating unit to the straw walkers.

4. Tailings return system: This system returns any grain that has not been properly separated back to the threshing and separating unit for further processing.

5. Chaff spreader: This component spreads the chaff evenly over the field, reducing the risk of fire.

6. Grain tank: The grain tank is where the harvested grain is stored until it can be unloaded.

7. Unloading auger: This component allows the operator to unload the grain from the grain tank into a waiting truck or other storage container.

Overall, the crop and straw discharge unit is a complex system that is essential to the efficient and effective operation of a combine harvester. Each of these parts plays a critical role in separating and discharging the crop material, ensuring that the harvested grain is properly stored and the field is prepared for the next planting season.
