Abstract

The invention relates to the technical means for irrigating agricultural crops and can be used for drip irrigation and sprinkling. The purpose of the invention is to enhance the functionality by allowing both drip irrigation and sprinkling. The water outlet includes a housing 1 with exit irrigation holes 3, spray openings 9 and 10, a hydraulic accumulator 5, a movable cover 4 with an inlet 2. There is a movable locking member 6 inside the housing 1, alternately blocking the inlet 2 and the outlet 3, which communicate with hydroaccumulator 5. Radial spraying holes 9 are made in the lid 4. A spring-loaded cuff 7 is mounted in the annular recess of the lid 4 with the possibility of blocking the holes 9 in the lid 4 and the holes 10 in the housing 1. 4 Il.

The invention relates to the technical means for irrigating agricultural crops and can be used for irrigation by drip irrigation and sprinkling.

The purpose of the invention is to enhance the functionality by conducting both drip irrigation and sprinkling.

Figure 1 shows the outlet, the General view; figure 2 - the body of the outlets, the section aa in figure 1; on fig.Z - a water outlet in a mode of a drop irrigation, a section; Fig. 4 - the same, on the mode of fine sprinkling, section.

The outlet (Fig. 1) includes a housing 1 with an inlet 2 and 3 outlet openings and a cover 4 and a hydroaccumulator 5 connected to it. Inside the housing 1 and the cover 4 there is a movable locking member 6 and a drain valve of the form of an elastic annular cuff 7, which tucked by a spring 8 The cuff 7 is installed in the recess of the cover 4 of the housing 1. The spraying holes 9 and 10 are located in the housing 1 and the housing cover and are hydraulically connected. The adjustment of the flow rate ii3 of the holes 9 and 10 (degrees of spraying) is carried out by moving the cover 4 relative to the housing 1. Irrigation perforated tubes 11 are inserted into the outlet openings 3 of the housing 1 with pressure suppressors 12 that are planted on the holes. The diameter is chosen based on the agrotechnical requirements of the cultivated crops.

In section A-A (Fig. 2) of the outlet 1, openings 13 are shown, through which water is supplied to the hydroaccumulator during the accumulation phase.

The outlet can operate in three modes: pulsed drip irrigation, fine sprinkling and combined irrigation (fine sprinkling and drip irrigation).

Switching the water outlet operation modes is centralized by varying the pressure of water in the supply piping network connected to inlet 2.

The operation of the outlet is as follows.

When the pressure in the pipeline network and, accordingly, in the inlet 2, is less than the pressure required to move the sleeve 7, the last spring 9 blocks water from entering the sawing holes 10 (Fig. 3). Water through the inlet 2, moving the valve body 6 into

the upper position enters through the openings 13 (Fig. 2) of the housing 1 into the hydroaccumulator 5 by pressing out the elastic edges of the locking member 6. The access of water to the outlet openings 3 is blocked. Hydroaccumulator filling with water occurs.

When a decrease pressure pulse is applied, the latter decreases in the inlet 2.

0 the hydroaccumulator the shut-off element 6 is moved downwards, and water through the apertures 13 enters the outlet apertures 3. Drip irrigation occurs through the distribution pipes 11 connected to the apertures

5 3. Further, when the pressure changes, the outlets will be operated at a predetermined interval in equal time.

Work spill when sprinkling

0 (FIG. 4) occurs in the following sequence. Water entering through the inlet 2 into the housing 1 moves the locking member b upwards and further through the openings 13 (FIG. 2) of the housing fills the reservoir of the camshaft hydroac5 5. Outputs of the housing 3 at the same time, they are separated by a locking organ with a hydroaccumulator cavity. The annular cuff 7, as the accumulator accumulator accumulates and the pressure rises, overcoming the resistance of the supper 9, moves down, opening access of water through the spray openings 10 to the atmosphere. There is a reduction of plants and air by sprinkling. The duration of each 5-cycle of sprinkling is regulated by the magnitude of the inlet pressure. When a low-pressure impulse is fed into the pipeline network, the latter decreases in the inlet 2 of the water outlet. Spring 8

0 cuff 7 is moved upwards, i.e. to the starting position. The supply of water from the water outlet housing to the atmosphere through the spray openings 10 is stopped.

With a fully filled accumulator, sprinkling is carried out. After applying a pressure drop pulse to the pipeline network in connection with

At its inlet 2, the pressure also decreases. The cuff 7 then returns to its original position (rises). Sprinkling stops. Under the action of pressure in the hydroaccumulator

5, the organ b moves downwards and the water from the reservoir of the hydroaccumulator through the openings 13 enters the outlet openings 3 and further along the perforated tube 11 to the plants. Drip irrigation is carried out. The process then repeats cyclically.
