CHASSI OF AGRICULTURAL PLANT WITH PARTIAL LOAD TRANSFER AND AGRICULTURAL PLANT

摘要

Partial load transfer agricultural planter chassis and agricultural planter The present invention relates to a chassis (1) used on an agricultural planter (100), to the mechanism (8) present in the structure of this chassis (1) that allows transfer partial load on the sides of this planter (100) to the inside of this planter (100) and the planter (100) containing this chassis (1). The aim of the present invention is to promote the partial transfer of the vertical load on the sides of a planter to the center of this planter by using a spring mechanism. This is achieved by the fact that the planter chassis (1) (100) comprises two support stops (6, 7) intermediate the contact between the central axis (4) and the inner end of each wing (2, 3 ), wherein the body of each stop (6, 7) is arranged perpendicular to the reference plane of each wing (2, 3) and projects downwardly towards the central axis (4); between which is located a partial load transfer mechanism (8) comprising a side support plate (9) and at least one spring (10); the spring (10) being disposed between the adjacent faces of each stop (6, 7) and projecting in a normal trajectory with respect to the plane of each stop (6, 7); the spring (10), when associated with the stops (6, 7), being able to alter the structural configuration of the planter chassis (1) (100) from an initial position, in which the wing planes (2, 3) define each other a relative angle of inclination greater than 180 degrees to an end position in which the relative angle of inclination of the wing planes (2, 3) approaches 180 degrees.
