Unit for moldless soil cultivation and layer-by-layer application of granulated mineral fertilizers

Abstract

The invention relates to agricultural engineering, in particular to technical means for non-moldboard soil cultivation and layer-by-layer application of granulated mineral fertilizers. The working element for layer-by-layer application of fertilizers consists of a rigid stand, a soil flow divider, a mounting hole, a chisel, a flat-cutting working element, a lower protective screen, an additional flat-cutting paw (wing), an upper protective screen, an additional fertilizer pipe, a main fertilizer pipe, a prismatic divider of the additional fertilizer pipe, and a prismatic divider of the main fertilizer pipe. The essence of the invention is that behind the rigid stand of the flat-cutting working element, additional loosening plates are installed symmetrically relative to the stand, with crumbling angles equal to half of the flat-cutting working element and a grip width equal to two-thirds of the latter, while behind the additional loosening plates, a protective screen is installed, connected to an additional fertilizer pipeline and a prismatic divider, and in the upper part, the additional fertilizer pipeline is connected to one of the pipes of the dividing head, the second pipe of the dividing head is connected to the main fertilizer pipeline, while the dividing head is equipped with an adjustable replaceable prism, which divides the flow of fertilizers into the main and additional fertilizer pipelines. The technical result is achieved due to the fact that behind the rigid stand of the flat-cutting working element, on the rear side, an additional flat-cutting paw with a half-sized crumbling angle is installed, adjustable in height, connected by a hinge to the rigid stand with the ability to change the height of the installation, in which a distribution device is installed, connected to an additional fertilizer pipeline, and the main fertilizer pipeline, connected to the branch pipe of the leveling chamber in the upper part, additionally equipped with a distribution head, where one branch pipe of the distribution head is connected to the main fertilizer pipeline, and the second branch pipe is connected to the additional fertilizer pipeline.
