The invention relates to agriculture and can be used in machines for the chemical protection of plants against diseases and pests.

 The aim of the invention is to reduce the flow and loss of fluid, as well as to reduce environmental pollution and improve dispersion quality.

FIG. 1 shows a schematic of the layout of the liquid; in fig. 2 shows section A-A in FIG. one.

The directional sprayer contains a return rotary screen 1, made in the form of a cylinder with an annular flanging 2 in the upper part, inside which a spreader body 4 is mounted on the drive shaft 3, to which the branch pipe 5 is connected to supply the working fluid.

The returnable pivoting screen 1 contains on the inner side of the screening 6, made around the perimeter of the window 7, and a cutter 8 with the window 9, made around the perimeter of the flanging 10, repeating the configuration of the window 7, but with a smaller size.

The cutter 8 is attached to the inner surface of the returnable pivoting screen 1 with movable fastening elements 11 with locking elements 12.

The returnable screen 1 on the ring element of the fastener 13 is mounted on the liquid collector 14, which was not dispersed from the sprayer, which is attached to the agricultural machine (not shown) by means of the fastener element 15 by the fixing element 16.

a part is deposited on the inner surface of the screen 1 and on the working surface of the shut-off device and flows into the collector 14. This liquid is then withdrawn for re-spraying. The presence of the cutter helps to prevent leakage of liquid droplets from the screen 1 and reduce the consumption of chemical. 1 hp f-ly, 2 ill.

- The collector 14 of liquid of the lower part is equipped with a branch pipe 17 of the liquid outlet The direction of exit of the dispersible liquid in the direction of the surface to be treated is fixed by the fixing element 18. To control the rotation of the return rotary screen 1 around the ring element of the fastening 13, the lever 19 serves.

The spray liquid directional operates as follows.

With the help of the return-pog lever 19, the collar screen 1 around the ring element of the fastening 13 is adjusted to the side of the surface to be machined.

A drive (not shown) of the spouting organ 4 is turned on and then the working fluid is supplied to the nozzle 5. During the rotation of the spouting organ 4, a circular torch of the dispersed liquid is formed, with some of the liquid escaping through the window 9 of the cutter 8 into the window 7 towards the treated surface, and the rest is deposited on the inner surface of the return rotary screen 1 and on the working surface of the shutter 8.

With a change in the frequency of rotation of the spouting organ 4, the trajectory of movement of the dispersible liquid drops changes. At the same time, in order to prevent coagulation of the dispersible liquid on the edges of the window 7, the cutter 8 is moved relative to the contraction

the rotary screen 1 on the movable fastening elements 11 so that the torch of the liquid dispersed by the spray body does not have contact with the flanges of the bis-edges of the window 7. The required adjustment of the shutter 8 relative to the return rotary screen 1 is fixed by fixing elements 12.

The air flow generated by the rotation of the atomizing body 4 moves part of the settled working fluid to the flange 2, where it collects, under the influence of gravitational forces, flows along the inner surface of the returnable pivoting screen 1, together with the fluid not set in motion airflow, and with liquid,. coming off the shutter 8 and its sampling fine 10, flare bypass 6 about 20, 7, B. collector 14. Then this liquid is discharged to the second spray through the nozzle 17.
