Description

chi

The invention relates to irrigation of agricultural crops and can be used on impulse sprinkling systems.

The purpose of the invention is to increase the uniformity of irrigation.

The drawing shows schematically the proposed pulse sprinkler, a general view.

The pulse sprinkler includes a housing 1 with a barrel 2, on which nozzles 3 are placed, and a hydroaccumulator 4, consisting of a concentration of elastic-elastic shells 5 and 6 located on the outer and intermediate shells 5 and 6, which have openings 7 for air removal from located between the shells of space. The inner shell 5 20 is made with a longitudinal elastic-elastic partition 8, located along the shell. It divides the cavity of the inner shell 5 into two longitudinal, isolated one from 25 u) compartments 9 and 10. The cavity of the housing 1 is connected to the cavity of the barrel 2 by a pipe 11 with two oppositely facing openings

the shell and the partition 8. As the compartment 9 is filled with water, energy accumulates in the elastic shells of the hydroaccumulator. Next, the valve 16 closes the left communication channel 14 and opens the right communication channel 14, through which water under pressure flows from the pipeline 15 into the cavity of the housing 1 and moves the locking bodies 13 to the left, as a result of which the left locking body first moves away from the opening 12 of the nozzle 11 and water from compartment 9 under the action of the elastic forces of the shells exits through pipe 11 into the barrel 2 and is released into the atmosphere through nozzles 3, rain in the form of soil. Upon further movement of the locking bodies 13 to the left, a passage of water into the compartment 10 opens and water under pressure flows into it. At the same time, the outflow of water from compartment 9 comes to an end, and the elastic forces of the walls of this compartment weaken and the partition 8, stretched by the action of filling the compartment 10 with water, bends towards the lowest resistance, i.e. in the direction of compartment 9 and expelling from it the remnants of water, helping with

1-2. In addition, the cavity of the housing 1 of the coarsely weakened elastic forces is confined to the cavity of the compartments: 9 and 10 of the inner shell 5, In the cavity of the housing 1, the locking bodies 13 interlocked with each other in such a way can be reciprocated that when one of them approaches the hole 12 of the nozzle 11, the other departs from the hole 12 opposite to the one on the pipe 11 (the locking mechanism of the locking bodies 13 is not shown). The cavity of housing 1 is connected by channels 14 to the supply pipe40.

check. When the valve body 13 opens the passage of water to the hydroaccumulator, the opening 12 in the nozzle 11 is blocked.

With further operation of the device

the valve 16 blocks the right communication channel 14, water flows through the left communication channel 14 into the cavity of the housing 1, moving the locking member 13 to the right. From the compartment 10 of the hydroaccumulator, water is discharged through the open branch 11, the barrel 2 and through the nozzles 3 into the atmosphere, and the compartment 9 enters the knock valve 16 blocks the right communication channel 14, the water goes through the left communication channel 14 to the cavity of the housing 1, moving the valve body 13 to the right. From the compartment 10 of the hydroaccumulator, water is discharged through the open nipple 11, the barrel 2 and through the nozzles 3 to the atmosphere, and the compartment 9 is fed by a conduit 15 equipped with a shut-off valve 16, for example, an electromagnetic dewatering water charge. The partition 8, by means of a switch with a time relay (not shown), is due to filling with water, providing alternate opening of the communication channels 14.

Pulse spraying apparatus operates as follows.

At this point in time, the valve 16 blocks the right communication channel 14, and the water from the supply pipe 15 under pressure passes through the left communication channel 14 into the cavity of the housing 1.
