BACKGROUND OF THE INVENTION The invention relates to devices for the in-soil application of liquid fertilizers.

The purpose of the invention is to ensure uniform distribution of fertilizers over the entire surface to be treated.

Fig. 1 shows a device for the subsoil fertilization with a fertilizer, top view; FIG. 2 is a section A-A of FIG. 1j on fig.Z - equalizer, axonometric

A device for soil fertilization of liquid fertilizers contains a rack 1, on which are mounted. working body 2, pressure pipe 3 and deflector installed under it, the Deflector is made in, in the form of an equilateral trapezoid of chamber 4 with installed - partitions 5 and sub-spherical equalizers 6 of fertilizer flow inside it, forming uio UHi-ni distribution compartment 7. On. The cover 8 of the chamber 4 is mounted to the rippers 9, and on the bottom 10 parallel to the sides of the chamber 4, the flow dividers 11 of the fertilizer 1P1 communicating with the receiving-distributing compartment are connected. In this case, the ticker edge of the fertilizer flow equalizers 6 is the surface of a hyperbolic paraboloid.

The device works as follows.

 fertilizers under pressure flow through the pressure pipe 3 into chamber 4 and accumulate in the supply and distribution compartment 7. When

by increasing the pressure in the compartment 7, the spring-loaded equalizers 6 of the fertilizer flow, overcoming the force of the springs, deflect and inform the channels 5 formed by the dividers 11 of the fertilizer flow with the receiving-distribution compartment 7. At the same time, It reflects and superimposes on the adjacent part of the flow, which is directed along the channels adjacent to the lateral edges, thus creating a greater flow rate in these channels.

- Leveler 6 flow from the bottom

the edge Z in the form of a hyperbolic paraboloid allows in those places of the receiving chamber where the jets overlap and, as a result, their outflow with greater speed, reduce the amount of fluid leaving the chamber, and where the velocity of liquid fertilizers is less (where there is no overlapping jets) amount of fluid. This is achieved due to the curvilinear shape of the lower edge of the equalizer, i.e., where the fluid velocity is large, the gap between the deflector and the lower edge is small and vice versa, where

0, the fluid velocity is low, and the gap is increased, which ultimately ensures a uniform distribution of liquid fertilizers over the entire surface to be treated. Equalization of fluid flow occurs when changing

second expenses when changing the angle of deviation of the equalizers, since the lower edge is represented not by a curve, but by a curvilinear one. surface ..
