Abstract

Planter tuber improved, the seeders discs planters rotating (5), upright and parallel to progress which have their active face drive dose of seed potatoes (30) and an opposite face mechanisms in which are radially mounted a pairs of lever cogedora-lever nailer (6-7) plurality operating through the disc (5), swiveling on respective support points (13, 17) intermediate between respective springs antagonists (12, 16) and sendos terminals drive (11, 15) are applied to relative and static cam profiles (8, 9) development circular to own paths cota-valley and cota-summit determining positions not active and operational counter spring and that, in rotation of this disc (5) these cams (8, 9) produce combinedly cycles operating said levers (6, 7) intended to take said doses (30) a collection hopper (2), and pour them over furrows recien opened in own progress seed drill, characterized in that in relation to the action tilt determined by said cams (8, 9), said levers (6, 7) are arranged with their means each other invested, taking the cogedora lever (6) a montage pinching of the seed (30) driven spring, whereby, its terminal drive (11) adjoins the head pinzadora (10), at the end of the lever (6) closest to the edge of the disc ( 5) and spring antagonist (12) is applied in the near to the center of disco (5) end by side lever (6) opposed this disc (5) while said lever nailer (7) has your terminal drive (15) closer to the center of the disc (5) and its return spring (16) between your support tilting (17) and head nailer (14) while end between such spring antagonist (16) and head nailer (14), this lever nailer (7) incorporates means practicable inhibitors his action; and said cam (8) actuator lever pinzadora (6) aro (8) comprises two half rings different angle width, are, a semi-ring lower (19), shorter, that under spinning for disco (5) sembrador, just stepped the digressive ramp (21) transition between the relative coordinate summit and valley and starts to angle sector nipping dose of seed (30), and an upper semi-ring (20) longest, beginning stepped according increasing ramp (22) return of the cota-valley to cota-summit, giving final to that sector angle nipping dose of seed (30), in which is understood driving position angle of the seed (30) determined by the summit between sudden jump and valley cotas said cam (9) actuator lever nailer (7); and wherein said two half rings (19, 20) at their other ends assembled in continuity cota-summit through a common plane oblique coupling, determining the semianillo lower (19) a ramp-up (24) transition between these coordinates valley and summit, which corresponds to the angular position planting dose of seed (30), where it meets also an initial ramp increasing (26) of the cam (9) actuator said lever nailer (7), transition between their respective cotas valley and summit.
