(57) Uses: chemical plant protection, paint coating. SUMMARY OF THE INVENTION: The walls of the nozzle portion forming the swirling chamber and the plugs are conical surfaces arranged in parallel. The tangential openings are made in the form of windows along the entire height of the walls of the housing, forming a twisting chamber. The sides of each of the windows, near and far from the outlet, are parallel to the forming conical surfaces of the nozzle part and the plug. The plug is made with a cone-shaped input end. The diameter of the base of the end face is chosen to be equal to the internal diameter of the annular cavity. 1 hp ff, 3 ill.

The invention relates to agricultural machinery and can be used for chemical protection of plants, for applying paint coatings, etc.

Sprayers are known to have a housing, interchangeable diaphragms with holes, a stem with a core, and a cap (BG Turbins and others. Agricultural machinery. M: Mashinostroenie, 1976. from 225-226. Fig. 152).

The disadvantage of such sprays is a significant unproductive pressure loss of the liquid, due to the high local resistance in the swirling chamber.

The aim of the invention is to increase the efficiency of the sprayer by reducing the hydrodynamic losses in the twisting chamber.

The goal is achieved by those. that the walls of the nozzle part forming the twisting chambers and the plugs are made in the form of conical surfaces arranged parallel to each other, and the tangential openings are in the form of windows along the entire height of the housing walls forming the twisting chamber, while the sides of each of the windows parallel to the forming conical surfaces nozzle parts and plugs. The plug can be made with a conical inlet end, the base diameter of which is chosen equal to the internal diameter of the annular cavity.

FIG. 1 shows the proposed sprayer; in fig. 2 is a view A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The atomizer has a housing 1, a nozzle part 2 with an outlet 3, a plug 4, a twisting chamber 5 formed by the walls 6 of the housing 1, a nozzle part 2 and a stopper 4, and the annular cavity 8 connected to the swirling chamber 5 by the tangential holes 7.

The walls 6 of the nozzle part 2 and the plugs 4 forming the twisting chamber 5 are made in the form of conical surfaces 9 and 10 parallel to each other, and the tangential openings 7 are in the form of windows along the entire height of the walls 6 of the housing forming the twisting chamber 5.

The sides 11 and 12 of each of the windows near and far from the outlet 3 are parallel to the generatrix of conical surfaces 9 and 10 of the nozzle part 2 and the plug 4.

The cap 4 can be made with a conical inlet end 13, the base diameter of which is chosen equal to the internal diameter of the annular cavity 8.

The spray works as follows,

The liquid is supplied to the annular cavity 8 of the housing 1 of the atomizer with a minimum, thanks to the conical shape of the end face 13 of the plug 4, loss of pressure and through the holes 7, the swirling chamber 5 enters, where, due to tangency of the holes 7, it receives rotational motion, and due to the parallelism of the surfaces 9 and 10 - directed movement towards the outlet 3. When exiting the latter, the liquid is sprayed,

The implementation of the twisting chamber formed by the walls of the body and two parallel conical surfaces of the nozzle part and the plug allows the liquid to move towards the outlet orifice, which reduces the energy costs of this movement and hydrodynamic losses.

head of fluid in the chamber of twisting. Performing near and far from the outlet of the sides of the tangential holes parallel to the conical surfaces of the nozzle part and the plug, and the B. HEIGHT of the tangential holes equal to the height of the wall of the swirl chamber provides an additional effect — reducing the pressure loss of the fluid entering the swirl chamber while ensuring the supersummer effect — their maximum throughput abilities.

Making the plug in the form of a double-sided cone, the diameter of the base farthest from the outlet orifice of which is equal to the smaller of the diameters of the annular cavity, allows us to obtain a new property — reducing the pressure loss of the fluid entering the annular cavity of the nebulizer.

The sprayer provides a significant reduction in the consumption of chemicals in the processing of fruit trees.
