SPRINKLER DEVICE Russian patent published in 2014 - IPC B05B3/04 

FIELD: agriculture.

SUBSTANCE: sprinkling device comprises an inlet for water and a sprinkler head forming an outlet for water, mounted with the ability of rotation relative to the main housing. Rotation of the sprinkler head is carried out by means of transmission of the sprinkler device, which is actuated by the rotating turbine with blades. The driving flow of water passes through the turbine, which forms at least a part of the total flow of water passing from the water inlet to the water outlet. The turbine is made with the ability of rotation in two opposite directions of rotation. For each direction of rotation one of two feeding channels is provided, each of which is provided with at least one inlet nozzle which determines the direction of running on. Using the switching device located downstream of both feeding channels the ability is provided to connect choosingly one of both feeding channels to the inlet for water. The path of the water passage is made optimally on hydrodynamics and with small twists for the flow passage. The feeding channel has a diversion of direction between the first part of the feeding channel, at least predominantly parallel to the turbine axis, and the second part of the channel extending substantially in the plane of turbine blades radially outwardly of the turbine blades. In the area of this diversion of direction the feeding channel is limited by the first outer wall and the first inner wall. The outer wall has a continuously curved passage free from kinks. The third part of the channel ends at the inlet nozzle, extends through an arc, at least partially around the turbine and tapers steadily. The third part of the channel has in the circumferential direction a continuously curved passage free from kinks in the form of an arc. The flow passage path extends from the inlet nozzle lying radially outwardly of the blades. The blades form a ring around the inner space. The nozzle is inclined at an angle of running on less than 45° relative to the tangent to the turbine. The path also passes through the lumen having at the radially inner ends of the blades between the adjacent blades, radially to the inner space. The guiding surfaces of the blades loaded by the flow from the inlet nozzle pass concavely curved and at an angle of running on, inclined relative to the radial line and in the direction opposite to the corresponding direction of rotation, pass to the inner space.

EFFECT: improved performance of start-up at low costs.
