Abstract:
1. A self-propelled agricultural machine for crop interseeding comprising: a unit with a drawing drive unit and a draw unit, wherein the drawing drive unit and the draw unit are operatively linked to each other by a mechanical coupling with a hydraulic drive of elevation; wherein the drawing drive unit comprises a land vehicle, which adheres to the soil, including an elevated chassis disposed at a substantial height, such that it can pass over the crops without causing any damage; wherein the drawn unit comprises a structure mounted on a metal frame bearing a single hopper housing at least one of seeds and fertilizers and including corresponding mechanically-actuated dispensers and drop chutes which are controlled using a gear train and an independent control wheel which is in contact with the soil, thereby defining the operating position; wherein the frame has a top end, and a bottom end; wherein a transversal longitudinal member is positioned at the top of the frame and multiple cavities having anchoring guides are positioned at the bottom end of the frame; wherein the multiple cavities house and position a number of modules belonging to planting/fertilizing independent bodies to the anchoring guides by subjection means for easy assembly and disassembly, varying the distance between furrows in discreet and selective form according to the crop; wherein the distance between the bodies is changed depending on the distance between the furrows of the crop, and wherein the independent bodies are kinematically associated with a hexagonal gimbal bar disposed along the length of a gauge of the unit and to a mechanism comprising an individual flexible transmission control for actuating a mechanical horizontal plate distributor, which is disposed inside the hopper housing at least one of seeds and fertilizer; wherein the individual flexible transmission control has a direction of displacement in the free spaces between furrows of the crops, wherein a distance between the bodies is allowed to be regulated according to the distance between the furrows of the crop to intercalate a second crop between the rows of the crop.
