The invention relates to a device for guiding the flow of solid chemical fertilizers meant to be used by a spreading equipment with two discs. According to te invention, the device consists of a guiding element (1) provided with two oblong holes (A), fixed at the internal part of some lower walls of a hopper (B) of a technical equipment for fertilizer administration (C), at the bottom of a conveyor belt (D), by means of some detachable assemblies, the oblong holes (A) allowing the change of position in the longitudinal plane and the change of an angle of fertilizer fall from the belt (D) onto some distributing discs (E and F), a deflector (2) being fixed onto the guiding element (1), the angle ( &alpha ) between some wings of said deflector (2) being determined depending on a distance between the distributing discs (E and F), hence, by the distance between some active zones of the discs (E and F) and a wall (3) closing some zones (G and H) of flowing of the fertilizer onto the discs (E and F).
