SU1501980A1 - Pulsed sprinkler - Google Patents

Abstract

The invention relates to agriculture and can be used on stationary irrigation systems. The aim of the invention is to reduce unproductive water discharges and waterlogging. The pulse sprinkler is equipped with a hydraulic distributor 4 and a hydraulic actuator 5 kinematically connected with it. The hydraulic distributor 4 is hydraulically connected to the pressure pipe 11, the cavity B of the locking member 3, channel 12 and channel 13 with the atmosphere. The hydraulic actuator 5 is made with two cavities, which are connected to the air and water cavities of the hydro-pneumatic accumulator. When moving water from the cavity B into the atmosphere, a pressure flow is created, which, after forming an artificial rain, is distributed over the nearby area. 2 Il.

Image 1) is related to the farm. It is intended for use on stationary irrigation systems for irrigation of various agricultural crops.

The aim of the invention is to reduce unproductive water discharges and non-humidification of the night.

FIG. 1 shows a sprinkler at the time of completion of filling; in fig. 2 is the same at the time of the end of the splash.

Pulse dozhdevatel consists of a sprinkler nozzle 1, the capacity of a hydronic-accumulator 2, a hydro-controlled organ 3, a hydrodistributor 4 and 1 of the idler-drive 5.

The capacity of the hydropneumoaccumulator 2 is divided:) with the flexible diaphragm 6 into the air)) and the water cavity B. The cavity A is filled with compressed air through the injection pump 7.

The hydraulically mounted closure body 3 has a single sided cuff 8, which is located in the cylinder 9. One side of the cuff is folded towards the water line b of the hydro-actuator accumulator, and the second side together with the cylinder 9 forms a cavity B occupied by () PH () 1H) of the organ 3

The valve 4 and the hydraulic actuator 5 are connected by a common rod 10.

The valve 4 is hydraulically connected to the pressure pipe 11 of the oropening system, channel 12 - with the cavity B of the valve body 3 and the drip 13 with the atmosphere. On channel 12, adjustable choke 14 is installed.

The hydraulic actuator 5 is connected by channels 15 and Hi with cavities L and b of the hydroinvine accumulator 2. The hydropneumatic accumulator has a perforated roof 17.

Under the action of compressed air in the nose .4, the hydraulic actuator 5 in the neutral position holds the IHTOK 10 in its extreme upper position (as shown in Figs. 1 and 2).

Pmpulse sprinkler works as follows.

The water from the pumping station through the pipeline 11 passes the valve 4, then through the drip 12. The throttle 14 enters the cavity B hydraulically with

of the porous organ 3, which is unmixed in the cylinder 9 to the extreme upper position and crossed 1) 1 exits into the sprinkler nozzle 1. From the cavity B into the water, pressing the elastic ends of the one-sided cuff 8, fills the cavity B under pressure compressing air in cavity A.

In the process of filling cavity B with water, the pressure in it will be equal to the pressure in cavity A. At the time of completion of filling cavity b, the pressure in it sharply increases, since the diaphragm 6 is perforated arch 17. Due to this, hydraulic actuator 5 will move the rod 10 to the lowest position . In this case, the valve 4 will break the cavity b with the pressure pipe and communicate it with the atmosphere. Under the action of air pressure in the bottom A, water from the cavity b under pressure will move the stop valve to the irrigated area. During the splash period, the pressures in Cavities A and B will also be equal. At the end of the upper pressure of the water in cavity b, it will sharply decrease to zero. B.

The cycle time is controlled by changing the flow area of the throttles 14.
