Intellectual multi-functional plowing unit

Abstract

A multi-functional plowing unit, combining the operation of the base fertilizer application in one pass, the moldboard plowing, the additional crumbling and the soil leveling is proposed and its efficiency is substantiated. A distinctive advantage of the new unit is the separate fertilizer application to a required depth in the arable layer in accordance with the requirements of a scientifically based farming system: phosphorus fertilizers are applied with a special plow attachment to the bottom of the ploughed furrow, potash and nitrogen fertilizers are distributed throughout the layer by plow moldboards. Additional crumbling and leveling of the plowed surface are carried out simultaneously with plowing by the attachment consisting of a combination of annular-spur and wedge-shaped discs. A prior-art plow body with rightand left-side plowshares was used in the design, which allows discerning the field board, reducing plowing resistance and increasing productivity of the unit. Technical and economic indicators of the multi-functional unit were calculated and analyzed. The qualitative indicators of plowing were also analyzed in comparison with conventional serial plows. Fulfilling the main objective of increasing productivity and reducing costs, the proposed multi-functional unit does not increase, but rather reduces the dust content in the arable layer compared to disc implements, thus reducing erosion processes.
