摘要
Head (200) for dispensing a volume of beans contained in a Cuba an air seeder comprising means for distributing the said volume of beads in a plurality of rows to be sown of a plot, allowing the head (200) distribution at least one first operating mode in which at least one row of the land is not sown, and at least one second operating mode in which a plurality of rows to be sown, is seeded a subset only substantially corresponding to a half-width of the seeder adjacent rows, said head (200) by a distribution duct (63) blowing air of the grains contained in said Cuba being fed. characterized in that said distribution means comprise at least one cap default sharing a flow of homogeneous grain density within a set of dividers (10) of grains in number at least equal to said rows to be sown each comprising one of said dividers (10) of grains: - means (100) passing a portion of said flow (100) grains which come at least one hole (64) formed between said lid (201) supply and the flange (62) of said conduit (63) blowing grains; - means (102) selective diversion of a portion of said flow (101) grain at the outlet of said means (100) for passage either to an outlet (103) for feeding grains to at least one of rows to be sown, or to an outlet (104) return said grains to Cuba, according to said first or said second modes of operation is selected; - means (105, 106, 107) control transfer movement of said means (102) selective deflection displaced at least in part to the top and bottom of the structure (108) divider cited (10 ) of grains, being actuated said control means by means (202) for actuating said means (105, 106, 107) control, for setting in rotation at least one first ring (203) movable activation said first operating mode and / or the setting in rotation of at least one second ring (300) movable activation of said second operation mode.
