Description

The invention relates to the mechanization of agriculture and can be used on wide-capacity circular irrigation machines operating in motion for the application of mineral fertilizers, microelements, biological preparations, herbicides and other pesticides in spraying and dusting modes.

A device is known for introducing microelements, chemical meliorants, herbicides, pesticides and macrofertilizers with irrigation water in drip irrigation systems, mobile pivot and frontal action irrigation machines and multi-support positional action frontal movement irrigation machines, containing a non-pressure tank, a level gauge, inlet and outlet pipes, a distribution pipeline, a valve, a pressure regulator, a fine filter with pressure gauges and a Venturi tube with shut-off valves (Patent RU No. 2343681).

The disadvantage is low versatility, inability to pollinate agricultural crops, and limitations in terms of application conditions.

The closest technical solution taken as a prototype is a device for introducing chemicals into sprinkler machines (Author's Certificate SU No. 1822642) including a container for mother solutions with an electromechanical mixer, a dosing pump, an air blower, transport water pipes placed along the water pipe of a sprinkler machine with carts, a dosing pump, a container, an ejector, and solenoid valves.

The disadvantages are the complexity of the design, low versatility, and a high probability of clogging of sprinklers.

An analysis of known technical solutions has shown that the technical problem in this area is the need to expand the range of tools used for the application of mineral fertilizers, microelements, biological preparations, herbicides and other pesticides in spraying and dusting mode using wide-capacity circular irrigation machines.

The technical result of the proposed solution is to ensure the versatility of a wide-capacity irrigation machine by expanding technological capabilities, while ensuring the quality of processing.

In order to solve the said problem and to obtain the stated technical result, a multi-purpose circular irrigation machine includes a solution tank, a dosing pump, a compressor, transport water pipes, carts, a hydraulic valve, a pressure gauge, and discharge pipes with sprinklers. In addition, the solution tank is equipped with a bubbling pipeline with a compressor connected to a water supply pipeline, and the sprinkler is made in the form of a tubular body, the lower part of which is connected by means of a thread to a sleeve fixed in a sealed body with a nipple for air supply, wherein the sleeve is made in the form of two chambers, lower and upper, separated by a partition with an opening in the center, while through holes are made in the side walls of the lower chamber, and a replaceable nozzle with a calibrated opening is installed in the end.

The proposed technical solution is illustrated by drawings:

Fig. 1 - general view of the device;

Fig. 2 - sprinkler, general view.

A multi-purpose circular irrigation machine 1 includes a main support 2, a supply pipeline 3, a hydraulic valve 4, running carts 5, a water supply pipeline of the machine 6, a compressor 7, a container with chemicals 8, and discharge pipes 9 on which sprinklers 10 are attached.

The pressure gauge 11 is installed on the air duct 12 leading from the compressor 7 to the sprinklers 10 to monitor the air pressure.

The dosing pump 13 is installed on the pipeline 14 leading from the container with chemicals 8 to the water supply pipeline 6 of the machine.

The bubbling pipeline 15 leads from the compressor 7 to the container with chemicals 8 for periodic pneumatic mixing of fertilizers, ensuring uniform concentration.

The supply pipeline 16 connects the supply pipeline 3 with the container with chemicals 8.

Sprinkler 10 comprises a tubular body 17 with a thread 18 at its lower end, onto which a sleeve 19 is screwed, divided into an upper chamber 20 and a lower chamber 21 by a partition 22 with a hole 23 in the center. Through holes 24 are formed in the side walls of the lower chamber 21 of sleeve 19. Furthermore, a replaceable nozzle 25 with a calibrated hole is installed in the lower part of sleeve 19.

A sealed cylindrical housing 26 is secured over sleeve 19 with a gap around its circumference, containing a nozzle 27 for air supply. A replaceable nozzle 25 is selected with the required opening depending on the required flow rate.

The machine works as follows:

When watering with clean water.

Pressurized water is supplied to supply pipe 3 and, with valve 4 open, to water supply pipe 6 of the machine. Water then enters discharge pipes 9 and sprinklers 10. Water passes through tubular body 17, enters sleeve 19, upper chamber 20, opening 23, lower chamber 21 and is sprayed through through side openings 24 of sleeve 19 and replaceable nozzle 25 with a calibrated opening. Sealed body 26 is removed. Chemicals do not enter through dosing pump 13 into water supply pipe 6 of the machine.

When applying fertilizers or chemicals by spraying.

The tank with chemicals 8 is filled. Water enters through the supply pipe 16 from the inlet pipe 3. The dosing pump 13 is turned on and the chemicals enter the water supply pipe 6 of the machine, the drain pipes 9 and the sprinklers 10. Water passes through the tubular body 17, enters the bushing 19 of the upper chamber 20, through the opening 23 into the lower chamber 21 and is sprayed through the through holes 24 and the replaceable nozzle 25 with a calibrated opening.

When applying chemicals by spraying with fine water-air streams.

From the dosing pump 13, chemicals enter the water supply pipeline 6 of the machine, the drain pipes 9 and the sprinklers 10. Chemicals with water pass through the tubular body 17, enter the sleeve 19, the upper chamber 20, through the opening 23 into the lower chamber 21.

At the same time, air from compressor 7 enters through air duct 12 into sprinklers 10 through fittings 27. Air enters sealed housing 26 and through through holes 24 into lower chamber 21, mixing with water and chemicals, forming a water-air mixture, spraying through replaceable nozzle 25 with a calibrated hole.

The use of the proposed technical solution ensures the versatility of a wide-capacity irrigation machine by expanding its technological capabilities, while ensuring the high-quality application of mineral fertilizers, microelements, biological preparations, herbicides and other pesticides in spraying and dusting mode.
