UNIT FOR SURFACE APPLICATION OF SOLID MINERAL FERTILIZERS

摘要

A unit for the surface application of solid mineral fertilizers includes an energy means, and a broadcaster, as a bunker with a rod conveyer, disk broadcaster working elements and a dosing device. The bunker is made with three sections with a drive of rod conveyers with the aid of hydromotors with couplings and throttles of regulating the speed of rotation controlling them through a control unit connected with sensors of the presence of nitrogen, phosphorus and potassium. Hydrocylinders of double-side action are arranged and tree-position working liquid dividers controlled by electromagnets are mounted to control them.
