Constructive disposition introduced in the header to agricultural machinery and implements in general

摘要

That is, basic and mainly in the inclusion of an intermediate arm (1), which will serve as an element of the union of the side arms (2) and (2 ') of the header (3), and the said arm intermediary is liable to be articulated in relation to the side arms, and s. And it is in element for the structuring of the header.Giving you the necessary mechanical resistance to the displacement of the machine or tiller, both during the planting, minimizing the shake generated by surface irregularities of the soil, which could influence the regularity of seeding, and where the change The positioning arm drive (4) of the header,In the conditions of planting and lateral movement of the equipment is promoted, in an automatic way, by means of actuation of a hydraulic actuator (5), which is controlled by the hydraulic system of traction machine or tiller, and to promote the joint The side arm supports the traction bar, in relation to the chassis (c) of the machine or tiller.Making the opposite side arm is articulated with the said arm intermediary, so that the hook (6) for coupling and locking, which is provided on the free end of the arm side opposite the traction bar, can promote, through the trigger (7) of the pin. Lock (8), the union or the disunity between the side arms of the header.
