The invention relates to agriculture and can be used in installations for soil liquid chemicals and fertilizer simultaneously with irrigation water when the sprinkler.

Known installation for spraying containing the reservoir, the pump and discharge pipe with nozzles and controls the fluid, mounted on a rotating console installed on the truck, driven by a hydraulic cylinder, communicating via the push rod with pokozachene wheels (French patent No. 2299918, MKI A01G 25/00).

The disadvantage of this design is poor spray liquid chemicals due to changes in pressure in the nozzle due to the correction performance of the pump depending on the traversed path.

Known device for making solutions of chemicals and fertilizers containing discharge pipe, mounted on a water conveyance pipeline sprinkler hydraulic anchor trolleys and synchronization system, the spray bar with nozzles made sectional, with the possibility of height adjustment between the support trucks and attached to the pressure pipe, regulators fluid supply mounted on each trolley and connected to the pressure pipe and the spray bar, and made in the form of the distribution valve, the stem of which is about cooperates with the push rod of the hydraulic anchor trolleys by means of spring-loaded rocker arm and pinned it stops (see A.S. No. 715077, MKI AM 7/00).

The disadvantage of this construction that it does not slip anchor trucks and different path, different anchor trolleys DM when making solutions of fertilizers and chemicals, i.e. on a different path reference carts poured the same amount of solution.

The invention aims to remedy these disadvantages.

The technical result is an increase in uniformity of making solutions of liquid chemicals and fertilizers by linking the amount of spray solution with the speed of individual anchor trolleys.

This is achieved by the fact that the installation is equipped with a system synchronization reference trucks sprinkling machines, which has the rod and rods, control valves, one of which is located between the pressure pipe and valve installation, the second is connected with the water conveyance pipeline, with control valves kinematically associated with the synchronization of the movement of the support trucks sprinkling machines.

The drawing shows a scheme of the setup for making chemicals and fertilizers.

Installation for making solutions of fertilizers and chemicals consists of the discharge pipe 1, is fixed on a water conveyance pipeline 2 DM, the spray bar with 3 nozzles 4. Opressive the General bar 3 are sectional between the support trucks and communicates with the pressure pipe 1 through distribution 5 and 6 regulatory valves. Distribution valves 5 are available on each truck and managed pokozachene 7 wheels 8 truck through the lugs 9 and 10, mounted on the push rod 11. The cylinder 12 through a system of levers 13 tells the rod 11 of the reciprocating movement relative to the guide 14. Curly rocker 15 distribution valve 5 is fixed in the two extreme positions adjusted by start spring 16. On the shoulder of the rocker arm 15 is attached to the roller 17. The cylinder 12 through the connecting valve 18, the valve 19 synchronizing the movement of the support trucks communicates with the water conveyance pipeline 2 sprinkler.

Control valves 6 are each anchor trolley, kinematically associated with regulating valves 19 and is controlled by the system synchronizing the movement of trucks, including thrust 20 and the rod 21.

The device operates as follows. Water from the water supply pipe 2 through the control valve 19 of the sprinkler system hydraulic machine, connecting armature 18 is supplied to the hydraulic cylinder 12. At the end of the stroke of the piston rod of the hydraulic cylinder 12 of the push rod 11 will occupy the leftmost position, the stop 10 will exert pressure on the roller 17 of the rocker arm 15, and it is under the action of kurkovas spring 16 will sharply turn around and push his shoulder at suplicio stock, will open it.

Liquid (solution of udobreniy chemicals), under pressure in the delivery pipe 1 through 6 regulatory and distribution 5 valves enters the spray arm 3 and through the nozzle 4 is sprayed on the field.

During the idle stroke of the rod of the hydraulic cylinder 12 and the rod 11 moves in the opposite direction. Emphasis 9 presses the roller 17 of the rocker arm 15, and it is under the action of kurkovas spring 16 will occupy its original position, closing the control valve 5 with their second flange. The supply of the solution of chemicals and fertilizers in the spray rod 3 and the nozzle 4 is stopped. Next, the rod 11 is engaged with the following focusarea 7 wheels 8, pushes him, and the whole cycle repeats.

Depending on soil conditions and terrain self-propelled anchor trolley pivot move at different speeds, and, therefore, are held and different way. If a cart behind, water conveyance pipeline 2 bends and pulls the pull 20 synchronization system. The result moves the rod 21. He presses on the control valve rods 19 and 6, in the initial section of these valves is increased. The cylinder 12 is quickly filled with water, the speed of the wheel 8 is increased, therefore, increases the path, and the irrigated area. Proportional to this displacement increases and open the enterprise of the valve 6, regulatory filing dose of solution through the control valve 5 to the spray bar 3. Thus, achieves a more uniform distribution of the solution of chemicals and fertilizers on the area. This process continues until, while behind the cart will not stand in one line with the other. The bending of the pipe 2 will decrease, therefore, will decrease and the flow of water into the cylinder 12, and the supply of the solution of chemicals (fertilizers) to the nozzles 4. Thus, a more uniform distribution of liquid fertilizers and chemicals on the square is the result of linking the velocity of individual trucks with the amount of opening of the regulating valve 6 is installed.

The invention in comparison with the prototype has the following advantages:

- uniform spreading of chemicals and fertilizers in area;

- reduction of losses of chemicals when you make;

- increase productivity C. agricultural crops;

- reducing the incidence of cultures;

- expansion of the functional and technological capabilities.
