Abstract

The invention relates to the field of agriculture, in particular, to sprinkling and irrigating machines of positional action for supplying solutions of fertilizers or other chemicals to irrigation water. The purpose of the invention is to improve the quality of work and reduce the energy intensity of the process. The hydraulic chopper for irrigation machines contains a tank 1, a feed 2 and a discharge 3 piping, a pressure irrigation piping 4. The feed piping 2 has an expanding nozzle 14 around which the output end 13 of the discharge pipe 3 is bent in a spiral. Perforated surface of the output end 13 made concave. Irrigation water enters the tank 1 and displaces the fertilizer solution, which enters the pressure irrigation pipe through the openings of the output end 13. 4 sludge.

Description

The device relates to the field of agriculture, in particular, to sprinkling and irrigating machines of positional action for feeding solutions of fertilizers or other chemicals into irrigation water,

The purpose of the invention is to improve the quality of work and reduce the energy intensity of the process.

FIG. 1 depicts a hydraulic sub-operator for irrigation machines, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2

The hydraulic chopper contains a tank 1 with an inlet 2 and an outlet 3 piping, which are connected to the irrigation pressure pipe 4. To the upper lid of the tank 1 are attached nozzles 5, 6, on which are installed the taps 7, 8 and supply pipe 2 with tap

9. A branch pipe 10 with a crane 11 and a discharge pipe 3 with a crane 12 are attached to the lower part of the container t. The output end 13 of the discharge pipe 3 is perforated and bent in a spiral around the expanding nozzle 14 of the supply pipe 2. The perforated surface of the output end 13 of the discharge pipeline 3 is made concave.

The hydraulic trimmer for irrigation machines works as follows.

Before starting work, the taps 7 and 8 are opened and the tank is filled with 1 fertilizer solution. Then the taps 7, 8 close and open the taps 9 and 11. Irrigation water from the irrigation pressure pipe 4 flows through the supply pipe 2 into the tank 1 and displaces the fertilizer solution through the discharge pipe 3 and the holes in the spiral bent out

ABOUT

end of 13 in irrigation water. After the fertilizer solution is dispensed, the taps 9 and 11 close and drain the water from the tank 1 through the nozzle with the tap, with the taps 7, 8 open, which is used to irrigate the crops.

Such a design allows creating the necessary backwater to the flow of water in the pressure irrigation pipeline and for supplying it through the supply pipe 2 to the tank 1 of the hydraulic bed feeder, and the cochlear shape of the discharge pipe 3 with its concave perforated side located in the direction of water flow reduces the pressure loss significantly and increases the flow rate of a solution of fertilizers when applying them to irrigation water.

Claims (1)

Claims of the invention A hydraulic sub-grinder for irrigation machines comprising a container with supply and discharge lines, inlet and the output ends of which are located in the pressure irrigation pipeline are directed in opposite directions and are made respectively in the form of an expanding nozzle and a perforated pipeline that is located in a plane perpendicular to the axis of the pressure irrigation pipeline, in order to improve the quality of work and reduce the energy intensity of the process , the perforated pipeline is bent in a spiral around the end of the expanding nozzle of the inlet pipeline, and its perforated surface is made concave Oh.
