摘要：
Seeder with a seed tank (46), a frame that carries it, a beam of bars (51) and a number of planting bars (2, 3) corresponding to the number of planting rows, said planting bars being joined to the beam of bars (51) by means of paths of four joints (4), where the base (5) of the chain of four joints (4) is fixed to the beam of bars (51) and presents at its ends paths joints (9, 10) for the connecting rods (6, 7) that run against the direction of translation (43) of the seeder, said connecting rods being connected by means of two joints (11, 12) to the connecting rod (8) which closes the chain of four joints (4) and guides the sowing fence (2, 3), where the chain of four joints (4) is subjected to elastic action that produces the grid pressure, characterized by the The fact that each joint (9 to 12) has a semi-rider (16) differently from the circular shape with at least two niches symmetrically arranged to accommodate two elastic elements such as rubber (22) and running parallel to the shaft and a profile (17) that is arranged in the semi-rider (16) and that with its outer surfaces cooperates with two elastic elements like rubber (22).Sembradora con un depósito de semilla (46), un bastidor que lo lleva, una viga de rejas (51) y una cantidad de rejas de sembrar (2, 3) que corresponde al número de filas de siembra, estando dichas rejas de sembrar unidas a la viga de rejas (51) mediante sendas cadenas de cuatro articulaciones (4), en donde la base (5) de la cadena de cuatro articulaciones (4) está fijada a la viga de rejas (51) y presenta en sus extremos sendas articulaciones (9, 10) para las bielas (6, 7) que discurren en contra de la dirección de traslación (43) de la sembradora, estando dichas bielas a su vez unidas mediante sendas articulaciones (11, 12) a la biela de acoplamiento (8) que cierra la cadena de cuatro articulaciones (4) y guía la reja de sembrar (2, 3), en donde la cadena de cuatro articulaciones (4) está sometida a acción elástica que produce la presió
