An agricultural machine having at least one crop processing work unit, a plurality of crop transport units operatively assembled as a straw walker step, wherein the crop transport units convey crop streams in opposite directions and are spaced apart defining a crop through-gap, and a cleaning device
An agricultural machine having at least one crop processing work unit, a plurality of crop transport units operatively assembled as a straw walker step, wherein the crop transport units convey crop streams in opposite directions and are spaced apart defining a crop through-gap, and a cleaning device having a forced-draught fan before the cleaning device, further comprising an exhaust fan located after the cleaning device, wherein the transport units are located between the forced-draught fan and the exhaust fan, wherein an air stream is produced by the forced-draught fan and the exhaust fan and is directed from the forced-draught fan to the exhaust fan, and wherein the air stream improves a cleaning process in the straw walker through-gap of the straw walker step. An agricultural machine having at least one crop processing work unit and an exhaust fan for carrying away a portion of the crop processed by working members for processing a plurality of crop streams out of an agricultural machine, comprising a crop distributing device operatively connected to the exhaust fan and having guide webs that are variable in position, wherein the crop distributing device has a first working position for receiving a first of the crop streams and a second of the crop streams and a second working position for receiving one of the crop streams, wherein in the first working position the first and the second crop streams are combined and discharged for broadcasting as a common crop stream, and wherein in the second working position the first of the crop streams is received and discharged and the second of the crop streams is conveyed and discharged from the working members in swath form separate from the first of the crop streams. The crop streams passing through the agricultural machine are conveyed with less turbulence. Long-stalked straw is deposited in a swath for later use, and short-stalked straw and chaff are discharged out of the agricultural harvester separate from and without whirling up again the crop swath.

What is claimed is: 1. A crop distributor for an agricultural machine having at least one crop processing work unit producing a first crop stream and an exhaust fan producing a second crop stream, said first and second crop streams being non-grain crop components, comprising; a crop distributing device operatively connected to the exhaust fan, having guide webs that are variable in position; a first working position for receiving said first crop stream and said second crop stream and wherein in said first working position, the first and the second crop streams are combined and discharged as a common crop stream; and a second working position wherein in said second working position, said first crop stream is discharged in swath form and said second crop stream is discharged in a separate direction from said first crop stream; wherein the guide webs have a side deposition working position, said side deposition working position discharging said second crop stream transverse to a direction of travel. 2. A crop distributor for an agricultural machine according to claim 1, wherein a central crop guide channels pivots between an engaged position and an unengaged position. 3. A crop distributor for an agricultural machine according to claim 1, wherein the guide webs are substantially straight. 4. A crop distributor for an agricultural machine according to claim 1, further including a common coupling mechanism for varying positions of the guide webs. 5. A crop distributor for an agricultural machine according to claim 1, wherein the guide webs are arcuate. 6. The crop distributor of claim 1 wherein said central path between an innermost pair of said guide webs is open in said first position and closed in said second position. 7. The crop distributor of claim 1 wherein said controlling step is executed mechanically via a series of guide pins, said guide pins being attached to said guide webs and said guide pins being disposed to move along guide slots in said distribution device. 8. The crop distributor of claim 1 wherein the second of the crop streams being discharged is substantially chaff and short straw. 9. The crop distributor of claim 1 wherein the first of the crop streams being discharged is substantially long straw. 10. The crop distributor of claim 1 wherein when the crop distributing device is operated in the second working position, the crop streams are staggered so as to not affect each other during discharge. 11. A crop distributor for an agricultural machine of claim 1 wherein said at least one crop processing work unit is a straw walker. 12. A crop distributor for an agricultural machine of claim 1 wherein said at least one crop processing work units is a rotor. 13. A crop distributor for an agricultural machine of claim 1 wherein said exhaust fan is a crop comminuter. 14. A crop distributor for an agricultural machine of claim 1 wherein said working unit is a multi cylinder threshing assembly. 15. A crop distributor for an agricultural machine of claim 1 wherein said first working unit is a rack vibrator. 16. A crop distributor for an agricultural machine of claim 4 wherein said mechanical coupling is remotely controlled. 17. A crop distributor for an agricultural machine having at least one crop processing work unit producing a first crop stream and an exhaust fan producing a second crop stream, said first and second crop streams being non-grain crop components, comprising; a crop distributing device operatively connected to the exhaust fan, having guide webs that are variable in position; a first working position for receiving said first crop stream and said second crop stream and wherein in said first working position, the first and the second crop streams are combined and discharged as a common crop stream; and a second working position wherein in said second working position, said first crop stream is discharged in swath form and said second crop stream is discharged in a separate direction from said first crop stream; wherein the guide webs are divided into a first group and a second group and when the first group and the second group are placed in said second working position said first group discharges crop laterally to a first side and said second group discharges crop laterally to an opposite side of the agricultural machine. 18. A crop distributor for an agricultural machine having at least one crop processing work unit producing a first crop stream and an exhaust fan producing a second crop stream, said first and second crop streams being non-grain crop components, comprising; a crop distributing device operatively connected to the exhaust fan, having guide webs that are variable in position; a first working position for receiving said first crop stream and said second crop stream and wherein in said first working position, the first and the second crop streams are combined and discharged as a common crop stream; and a second working position wherein in said second working position, said first crop stream is discharged in swath form and said second crop stream is discharged in a separate direction from said first crop stream; wherein a guide channels is centrally arranged in said crop distributing device, and when said guide webs are in said second position, said central channel is in a closed position. 19. A crop distributor for an agricultural machine having at least one crop processing work unit producing a first crop stream and an exhaust fan producing a second crop stream, said first and second crop streams being non-grain crop components, comprising; a crop distributing device operatively connected to the exhaust fan, having guide webs that are variable in position; a first working position for receiving said first crop stream and said second crop stream and wherein in said first working position, the first and the second crop streams are combined and discharged as a common crop stream; and a second working position wherein in said second working position, said first crop stream is discharged in swath form and said second crop stream is discharged in a separate direction from said first crop stream; wherein the crop distributing device has three crop guide channels, which are adjustable from a first crop discharge direction, pointing essentially in a direction aligned with the direction of travel, to a second crop discharge direction, pointing transverse to the direction of travel. 20.
