SEEDING MACHINE WITH REGULATED LOAD DEVICES ON THE SIDE WINGS TO COMPLAIN WITH UNEVEN LAND LEVELS

Claims

Agricultural seeders and fertilizer spreaders, regardless of type, must follow the contours of the land to ensure that all seeding units penetrate the soil evenly, thus guaranteeing that all deposited material is placed at the same depth for the efficiency of the sowing or fertilization process. The invention is based on the use of lateral wings that are articulated to the machine's frame and can pivot vertically. Each wing is connected to a hydraulic cylinder whose load is predetermined based on soil characteristics and is automatically regulated using electronic controls, regulating valves, and hydraulic pressure sensors.Since the cylinders always push the toolbars downwards, it ensures that all the seeding units penetrate the soil evenly, regardless of whether the machine encounters a dip or rise in the ground, guaranteeing that the seed is always deposited at the same depth. Additionally, each toolbar belonging to the side wings pivots within supports that limit its vertical and horizontal movement, preventing stress that could damage its structure.
