Description

one

The invention relates to a technique for irrigating agricultural crops and is intended for subsurface irrigation of orchards and vineyards.

The purpose of the invention is to increase the reliability of work.

FIG. 1 shows a diagram of the connection of subsurface sprinklers to the water transport network; in fig. 2 - soil irrigation spreader, general view.

Sprinkler 1 is connected to the network through a distribution pipe with a float level 2 regulator. Sprinkler 1 contains a water outlet 3 and in the form of two concentric tubes 4 and 5 plugged from the bottom, perforated in length and covered with a nylon mesh 6, the space between the tubes is filled with porous material 7, the specific moisture capacity of which exceeds the soil moisture capacity. The inlet 8 of the pipe 4 of small diameter is equipped with an elastic funnel 9, fixed in the groove 10 on the inner surface of the pipe 5 of large diameter.

The sawdust wood mixture was used as the porous material 7. During the irrigation process, this mixture is well impregnated with water and as the water is sucked out by the roots from the soil, moisture from the wood mixture is transferred to the soil even when the irrigation is completed. Large specific: the capacity of the mixture compared to the specific moisture capacity of the soil provides one-way transfer of water from the wood mixture to the soil.

Nylon grids 6, stretched on both pipes 4, 5, do not allow wood-10

The mixture gets into the inside of the pipe 4 and falls out through the perforations in the pipe 5. In addition, the external nylon mesh 6 on the pipe 5 prevents the sprinkler from clogging it with soil during installation in the area of the root system of the plant. Intra soil sprinkler operates as follows.

After water is supplied to irrigate, the internal cavity of the irrigator is filled with water, which through the funnel 9 into the pipe 4 of small diameter, through the holes in its walls, the nylon mesh 6, the porous material 7, the holes in the tube 5 and the nylon mesh 6 pulled over it the soil. The sprinkler is replenished with water to a predetermined level with the help of a level 2 float regulator.

Claims (2)

1.In-soil sprinkler containing a water outlet and two water-permeable concentrically arranged plugged tubes, characterized in that, in order to increase reliability, the tubes are fastened in the upper part with an elastic funnel communicating the inner tube with a water outlet, and the space between the tubes is filled with porous material moisture content of which is higher than the specific capacity of the soil. 2. The irrigator according to claim 1, about tl and h ai y and with the fact that sawdust-wood mixture is used as a porous material.
