Automated Multifunctional Tillage Machine

High-quality soil tilling using a tillage machine depends on the well-run, coordinated operation of all its operating elements and units [1–3]. The considered structure of an automated multifunctional tillage machine allows, per run, carrying out vertical soil paraplowing to a depth twice exceeding the cultivation depth, subsurface loosening of the soil with cutting of the weeds, and additional grinding and harrowing of the soil to the depth equal to the cultivator width. The aim of this work is to improve the quality of the soil tillage due to automatic regulation of the specified depth of its tillage and increase the yield of the cultivated crop achieved by the fact that the first and third sections of the automated multifunctional tillage machine [4, 5] are equipped with a control unit of the actuating mechanism of their drive located in the cabin and with protective housings of the hydraulic cylinder rods, on the internal part of which are located local magnetic field sources (permanent magnet of electromagnet) closing the control circuit of the actuating mechanism. Each housing of the hydraulic cylinders is equipped with protective reed switches (sensors) installed at a predetermined adjustable distance from each other. The automated system of regulation of the soil tillage depth has a simple design and is reliable in operation, and the quality parameters of the machine increase up to 10% due to this.
