AGRICULTURAL MACHINE AND METHOD FOR OPERATING AN AGRICULTURAL MACHINE, DISTRIBUTOR TOWER OF AN AGRICULTURAL MACHINE

摘要

It is a distributor tower (10) for an agricultural machine (12) for dispensing Verteilgut disclosed. The distributor tower (10) comprises a riser pipe (22) for feeding a distributor air volume flow into a distributor head (24) adjoining the riser pipe (22), a multiplicity of outlets (26) on the distributor head (24) for dividing the distributor air volume flow at least one shut-off means (32), by means of which either the seed line (28) or the return device, is branched into a plurality of distributor air volume flows, which outlets (26) each branch into at least one seed line (28) and at least one return device (30) (30) is shut off, so that the Verteilgut-air flow is passed according to a position of the at least one shut-off (32) either in the seed line (28) or in the return device (30) and at least one bypass channel (46) which the seed line ( 28) and the return device (30) connects pneumatically to each other, wherein the bypass channel (46) at least at an opening in the at least Seed line (28) and / or in the at least recirculation device (30) is associated with a flow-conducting element (48) via which an air volume flow rate of Verteilgut-Luftvolumenstromanteil is branched off.;Further disclosed are an agricultural machine (12) and a method of operating an agricultural machine (12) for spreading dispensing.
