TURBINE TYPE SPRINKLING UNIT Russian patent published in 2021 - IPC A01G25/00 B05B3/04 

FIELD: sprinkling devices.

SUBSTANCE: invention relates to the field of sprinkling devices. The sprinkler contains a hollow cylindrical body (1) with a guide rod coaxially installed in it, a fluoroplastic gasket with the ability to rotate along the rod, a deflector (8) and grooves (5) on the working surface, limiting a lock nut on the threaded part of the deflector. The deflector (8) is made of two parts, rigidly fixed to each other. The upper part is made in the form of a jet impeller made of a stainless bundle of petals in the form of curved plates (9) and arranged in a circle and overlapping each other towards adjustable irrigation pipes (6) with grooves (5) and with an inclined-convex surface in the horizontal and vertical planes. The lower part is made of high strength plastic with a movable bearing along the cylindrical rod and a fixed shoulder at the bottom and an annular groove for a restraining rubber ring in the form of a sleeve in front of the bearing. The cylindrical body (1) is rigidly connected from above by a guiding vertical rod in the form of a fixed axis and is also made as a whole from high strength plastic with at least three grooves (5), evenly spaced to the inner axis of the cylindrical body. The inner cavity of the grooves is made with an internal thread for screwing into them hollow adjustable irrigation pipes (6), the outer end of which is equipped with a rigid nut (7) for a key. The adjustable irrigation tube is made with the ability to change its position in height relative to the jet impeller. Hydraulically ascending jets in their upper part of the body interact with the lower plane of the jet impeller, with the possibility of axial rotation of the jet impeller with a fixed deflector around the vertical guide rod. The jet impeller in plan and in diameter is made larger than the outer diameter of the cylindrical body with elements for supplying a stream of water.

EFFECT: increasing the reliability of the apparatus and expanding its working pressure and obtaining high-quality fine-dispersed rain.
