摘要:
An agricultural harvester (10) includes a chassis (12), with a separating system (24) and a residue handling system (70) each carried by the chassis (12). The separating system receives a flow of crop material producing a chaff flow (78) and a residue flow (80). The residue handling system (70) receives the chaff flow (78) and the residue flow (80) from the separating system (24), and the residue handling system (70) includes a residue chopper (72) operationally positioned immediately above a residue spreader (74). The residue spreader (74) is oriented to receive the chaff flow (78) and the residue flow (80) chopped by the residue chopper (72).
摘要:
A spreader arrangement (12) for an agricultural harvester (10) includes a pair of spreader discs (16), at least one cover plate (24) and a windrow chute (26). The spreader discs (16) are generally horizontally arranged and rotatable in a counter rotating manner. Each cover plate (24) is positioned at a location above a respective spreader disc (16), and is operable to inhibit a flow of crop material to the respective spreader disc (16) when positioned above the respective spreader disc (16). The spreader arrangement (12) is characterized in that the windrow chute (26) has an entrance end (30) positioned below the pair of cover plates (24) and above the pair of spreader discs (16), whereby crop material is discharged from the top of the cover plates (24) into the windrow chute (26).

摘要:
An agricultural harvester (10) includes a chassis (12), a threshing and separating system (24) for separating grain from MOG, and a grain cleaning system (26) for further separating grain from residual MOG. The grain cleaning system (26) has a main grain pan (44), an intermediate grain pan (102) located beneath and rearward of the main grain pan (44), and at least one sieve (46, 48, 50) located beneath and rearward of the intermediate grain pan (102). The main grain pan (44), the intermediate grain pan (102), and the at least one sieve (46, 48, 50) are so arranged that the mixture of grain and residual MOG undergoes a first fall step (100) from the main grain pan (44) to the intermediate grain pan (102), and a second fall step (104) from the intermediate grain pan (102) to the at least one sieve (46, 48, 50).
