摘要：
A centrifugal machine for broadcasting mineral fertilizers relates to the field of agricultural machine-building. The centrifugal machine comprises a tank, in the bottom of which at least one discharge opening with a dosing shutter is made, under said opening a centrifugal broadcasting unit, made as at least one disk with blades and equipped with a rotary drive, is arranged, and said machine also comprises an agitator, which is hingedly fixed above the bottom of the tank near the discharge opening and connected with the rotary drive. The agitator is made as a holder, to which fingers, the free ends of which are directed towards to the discharge opening, are fixed. The holder of the agitator is shaped as a plane, and the fingers &ndash； as cylinders, the axes of which are in parallel to the rotational axis of the agitator and are mounted with a space equal to the sum of the double diameter of a finger and the size of a fertilizer particle (granule), and a difference between the distances from axes of two fingers, with the same numbers, arranged on different sides of the rotational axle of the agitator, to this axis equals to a half of a space of arrangement. In doing so the space between the lower ends of the fingers of the agitator and the bottom of the tank equals to a half of the maximum size of a fertilizer particle allowable by the standard. The new design brings to reducing in squeezing of foreign bodies and fertilizer granules between the bottom of the tank and the agitator that provides increasing in the reliability of the design of the machine and reducing in damaging fertilizer granules.Відцентрова машина для розсівання мінеральних добрив належить до галузі сільськогосподарського машинобудування. Відцентрова машина містить бункер, в днищі котрого виконаний принаймні один випускний отвір з дозувальною заслінкою, під яким розміщений відцентровий розсівальний апарат, виконаний у вигляді принаймні одного диска з лопатками і обладнаний приводом в обертальний рух
