Abstract

The invention relates to agriculture and can be used in irrigated agriculture when irrigating from closed pipelines. The purpose of the invention is to increase reliability by reducing the possibility of clogging. The outlet consists of a vertical pipe 1, through which water is supplied from the underground pipeline, outlet slots 2. At the outlet end 3, the pipe 1 is connected to the elastic irrigation sleeve 4 in the form of a conical funnel with a slot at the end 5. In the cavity of the body 6, the outlet slots 2 are placed along its perimeter in the form of longitudinal slits. The latter overlap with a locking member, made in the form of an elastic joint with elongated two rows of segments of petals overlapping each other around the perimeter of nozzle 1. The first row of petals overlaps the slits 2, and the second row of petals has longitudinal slots between the first row of petals. When the pipeline is filled with water, the nozzle 1 is filled and the water leaves through the slots 2. In this case, the segments of the petals of both rows around the perimeter are withdrawn by the free end and the connection takes the form of a flashlight. The water moistens the area closer to the housing 6, above it. The soil above the irrigation cone funnel 4 softens and the funnel 4 begins to work with its full cross section.

Description

The invention relates to agriculture and can be used in irrigated agriculture when irrigating from closed pipelines.

The purpose of the invention is to increase reliability by reducing the possibility of clogging.

Figure 1 shows the water outlet irrigation pipeline, the position of the initial stage of the work; figure 2 - the same, in the Open position; fig.Z - the same, in the closed position; on . 4 and 5 are sections A-A and BB, respectively.

The irrigation pipeline water outlet consists of a vertical pipe 1, through which water is supplied from an underground pressure pipe, and outlet slots 2. At the outlet end 3, pipe 1 is connected to an irrigation hose 4, made in the form of a conical funnel made of an elastic material with a slot at the end 5. In the cavity of the housing 6 on the side surface of the nozzle 1, the water outlet slits 2, placed along its perimeter in the form of longitudinal slots, overlap with a locking member made in the form of an elastic joint 7 with elongated two rows from cuttings of petals 8 and 9, overlapping each other along the perimeter of nozzle 1, the first row of petals 8 blocking the slots 2, and the second row of petals 9 - longitudinal slots between the first row of petals 8.

Water outlet irrigation pipeline works as follows.

In the initial position, while there is no water in the pipeline, both rows of lobes 8 and 9 overlap the slots 2 and the longitudinal slots between the first row.

petals 8 around the perimeter of the nozzle 1 in the cavity of the housing 6, and irrigation

the sleeve 4 is compressed (Figure 1), blocking the access of the soil to the nozzle 1.

In the process of filling the pipeline with water, the nozzle 1 is filled and the water leaves through the slots 2,

pieces of petals 8 and 9 along the perimeter of waste are withdrawn from the free end, and connection 7 takes the form of a flashlight. As a result, the water moistens the area closer to the housing 6, above it.

The soil above the irrigation cone funnel 4 softens, and the funnel 4 begins to work its full cross section, i.e. water flow through the outlet is calculated with small

losses to the surface in the irrigation furrow or strip. In this case, watering goes without fountains.

The water supply to the pipeline is stopped. With the loss of water hose

Compound 7 at end 5 compresses due to vacuum in the pipeline, closes the nozzle 1 from above and begins to sink into the washout funnel, but the connection does not pull into the nozzle 1. The presence of free petals 8 and 9 of smaller dimensions has a positive effect on the increase in sensitivity and on closing slots 2 in the cavity of the housing 6, since the main force pressing the sleeve 7 does not depend on the pressure of the water in the pipeline, but on the perception of the pressure of water in the washout funnel. This achieves self-sealing of elastic closures with a high degree of sealing and reliable operation.

The proposed design is reliable in operation, since it is absent for

c z foam dome space and outlet. This is due to the presence of elastic closed petals around the perimeter of the nozzle, adjacent to the water outlet slots and to the slots between the petals of smaller sizes, as well as the connection of the conical funnel of elastic material. In addition, the remaining air in the under-dome space does not allow penetration of the soil, precipitating in the washout funnel, into the inside of the nozzle, and simplifies the manufacturing technology of the structure.
