Abstract

A device for rotary sector sprinkling, especially for a self-propelled mining combine, which is equipped with channels for supplying liquid under pressure, flow channels in the head frame, a rebate element introducing liquid into the flow channels, and the spraying liquid chamber, characterized by the fact that on the rotating shaft (1 ) with internal axial flow channels (1.1), a separation ring (2) is built-in and immobilized in relation to the shaft (1), the through radial holes (2.1) of which correspond to the through radial connecting holes (1.2) made between the internal axial flow channels (1.1) and the surface the outer shaft (1). In the inner chamber (3.1) of the body (3) with the inflow channel (3.2), closed with the outer surface of the separating ring (2) and sealed with rotary seals, there is an eccentrically rotating pin (6) with a built-in bearing (7). The outer surface of the separation ring (2) and the bearing (7) is banded with a flat belt (8) with a width covering the through radial openings (2.1) of the separation ring (2) and smaller than the width of the inner chamber (3.1) of the body (3).
