precision two-row seeder and single feeder driven by tractor or two-wheel tractor for use in conventional or no-till

摘要

The present invention relates to a machine for sowing large grains such as corn, beans, soybeans, among others. The machine consists of a seeder using a single perforated horizontal disk seed feeder (5) for two planting rows. The seeds are conducted by means of two flexible hoses (7) arranged internally to the other (telescopic system). each line consists of a center groove depth control wheel (10), a smooth cutting disc (11), a groove rod (12) with an appropriate rake angle for easy ground penetration and a compactor wheel with central relief (13). The chassis (6) supports the seed container, the drawbar (9) and the drive wheel (8) of the spring-loaded articulated torque feeder (19). for use with animal traction heights (1) must be fitted with height adjustment and the animal traction coupling system (2) and also with height adjustment. For use in mechanical traction, remove the rabbits and the animal traction coupling system and assemble the mechanical traction coupling (3) and a pair of stirrups (4). The seeder can be pulled by animals or by two-wheel tractors, featuring two traction systems. The seeder can also be used for both no-tillage and conventional tillage characterizing the possibility of use in two tillage systems.
