A machine for applying loose mineral fertilizers includes a tank mounted on a frame, a distributing unit as a screw feeder, connected to a sectional case. The sections of the latter are mounted with a gap, connected by partitions and equipped with circular disks arranged in the area of gaps and with holders as continuous tapes mounted on the side of the outer edges of the circular disks. In the area of gaps shields of a roof-like shape are mounted. Said shields are directed inside the case and fixed to the partitions with a deflection in the direction opposite to the rotational direction of a working element for an angle larger than an angle of fertilizer friction along surface thereof. The shields are arranged stepwise in the rotational direction of a distributor, and a projection thereof onto the internal surface of the case exceeds the area of gaps. |
