DISTRIBUTION MACHINE AND METHOD FOR SOWING OF GRANULAR MATERIAL

摘要

Distributor (10) and method for granular distribution material, in particular for seed, fertilizer or the like. The distributor (10) comprises a reservoir (14) and a downstream metering device (32) for metering the Verteilguts in one by means of an air conveyor unit (36) Air volume flow, a distribution tower (38) with a riser (40) and a subsequent distribution head (42), in which a distribution of a Verteilgutluftvolumenstroms in a plurality of Verteilgutluftvolumenströmen corresponding to a number of distributed over its circumference outlets (44). A plurality of coulters (20) for depositing the Verteilguts each having a separating device (48) is assigned, by means of which the by a seed line (46) conveyed Verteilgut even or isolated and then on a coulter (20) associated seed tube (24) in Floor is deposited. Between the outlet (44) of the distributor head (42) and the separating device (48) a shut-off device (50) with a switch (52) is arranged, by means of which the Verteilgutluftvolumenstrom in the direction of the seed line (46) or in the direction of a return region (54) is directed.
