The invention relates to agriculture, in particular to the irrigation technique, and is an improvement of the known manurer to sprinkling and irrigation machines.

The purpose of the invention is to improve the work of the fertilizer operator when applying pesticides or liquid fertilizers to irrigation water.

The drawing shows a diagram of the fertilizer,

Feed 1k contains a diaphragm pump consisting of bodies 1 and 2, separated by membrane 3 into pressure chamber 4 and submembrane chamber 5, and rod 6.

The hydraulic pump is made in the form of power and return cylinders: 7 and 8, the rods of which are fixed pivotally on the machine.

The piston cavity of the power cylinder 7 communicates with the submembrane cavity 5 through the distributor 9 with the pressure pipe 10 of the machine. The piston cavity of the return cylinder 8 is in communication with the pressure pipe 10 via the throttle 11 and the check valve I2. The double-arm lever 13 is kinematically associated with the housings of the hydraulic cylinders 7, 8 and the pump rod 6. The gas ha 14 is kinematically connected to the distributor 9, the drain cavity of which is connected to the perforated pipeline 15 and the tank 16, in which the float switch 17 is installed.

The chamber 4 of the injection of the membrane pump is connected to the suction side

pump housing 1, thereby changing the stroke of the piston 20 and the cycle feed. During the course of the injection: neither the membrane pump first pumps the volume of liquid from cavity 27 into QD 1 O, and in the upper position of the piston 20 a passage opens to the solution in the annular cavity 28, channel 29. Through the valve 22 and the three-way valve 30, the solution enters either into the NT 10 or into the supply tank 18. 1 Il.

valve with feed tank 13 for liquid fertilizers or pesticide solutions.

On the cylindrical protrusion of the housing 1, a block 19 of additional cylinders is installed, in which the differential piston 20 and valves 21 and 22 are placed. In the housing 1, a nut 23 is installed on the stud in the slot of the block 19. Between the block 19 and the cylindrical protrusion of the housing 1 there is an elastic ring 24 The position of the block 19 of the cylinders 19 relative to the housing 1 is controlled by the pointer 25. In the piston 20 there is a valve 26 which communicates the pumping cavity 4 with the supra-piston cavity 27, the piston cavity of the small additional cylinder is permanently communicated with pressure pipe 10 of the machine. The cavity 27 of the large additional cylinder through the valve 21 also communicates with the pressure pipe 10 of the machine. The annular cavity 28 through the channel 29, the valve 22 and the three-way valve 30 communicates either with the pressure pipe of the machine 10 or with the tank 18.

On t 14 of the distributor 9, the limit stops 31 are installed.

A pressure regulating valve 32 is installed in the pipeline, which connects the injection chamber 4 of the membrane pump with the supply tank 18, one of the cavities of which is connected to the pressure pipe 10.

During the discharge stroke, water from the pressure pipe 10 through the distributor 9 enters the piston

the cavity of the power cylinder 7 and the submembrane chamber 5. By the force of the power cylinder 7, the double-arm lever 13 is set in motion and through the rod 6 moves the membrane 3 to the upper position. At the end of the pumping stroke, the lever 13, interacting with the stops 31 ti 14, switches the distributor 9, as a result of which water is blocked from the machine’s discharge pipe 10 into the cylinder 7, and the piston cavity of the power cylinder 7 and the submembrane chamber 5 are connected to the perforated the pipe 15 and the tank 16. Under the action of the forces of the return cylinder 8, the two shoulders lever 13 moves in the opposite direction, as a result of which a suction takes place in the diaphragm pump. During pump suction, the return cylinder 8 communicates with pipe 10 only through a throttle, and during pumping through a choke 11 and check valve 12. During suction, dissolved fertilizers or pesticides from the supply tank 18 through the intake valve 11 enter the injection chamber 4. At the same time, under the action of the pressure of the liquid of the pressure pipe 10 to the small diameter of the differential piston 20, the latter is displaced downwards and the cavity 26 is filled through the valve 26. When the membrane pump is pressurized by the pressure of the solutions in the chamber 4, the piston 20 moves up and displaces the solution from the cavity 27 through the valve 21 and the pressure pipe 10 of the machine. In the upper position, the piston 20 with its lower edge opens the passage to the solution from the chamber into the annular cavity 28, channel 29 and through the valve 22 and the three-way valve 30 to the pressure pipe 10 of the machine or into the container 18 to ensure mixing of the solution. In order to unload the diaphragm 3 of the pump, when the solution is drained into the supply tank 18, a regulator 32 is installed on the drain pipe

laziness, which ensures the passage of the solution only when the pressure in front of the valve 32, which is close to

value to the pressure in the discharge pipe 10.

When pesticides or fertilizers are applied with irrigation water, the adjusting nut 23, depending on the required pesticide application rate, establishes the rounded position of the cylinder block 19 relative to the housing 1. When the cylinder block 19 is moved, the piston 20 and hydraulic flow of the pesticides in the discharge pipe 10 changes. Pointer 25 indicates the value of the set feed cycle.

When the unit is operating, water is constantly fed into the container 16 and the float switch 17 is in the upper position. In this case, the contacts of the electrical switch 17 are closed. When stopping the fertilizer. The water supply to the tank 16 is stopped, the water level in the tank is lowered, the float switch 17 is lowered and the contacts of the electric system of the 1-stage sprinkler are open.
