Description

The invention relates to agricultural reclamation, in particular to drip irrigation.

Known drip outlet, comprising a housing with two communicating hole chambers, inlet and outlet openings and a float valve located in the upper chamber, in which, in order to improve reliability, the water outlet is equipped with a second float valve installed in the lower chamber, both valves are made bilateral action; in order to expand the range of operating pressures at a given flow rate, adjustable inserts (SU, copyright certificate No. 858670. M. class ³ A 01 G 25/02. Mounted drip outlet / AS Knyazev, GN Malyshkin were mounted in the openings of the chambers , I.N. Andoksin et al. (USSR) .- Application No. 2441080 / 30-15; Stated 01/05/1977; Publ. 30.08.1981, Bull. No. 32).

The disadvantages of the described drip outlet, despite the presence of two chambers for reducing water pressure, include a low degree of distribution of water over time, high requirements for water purification, a strictly vertical position for normal operation, and the need for additional devices for fixing in the working position.

Known dropper containing a conical shape with an inlet and outlet, and a float installed in it, in which, in order to increase reliability and efficiency, it is equipped with a strainer that is installed in the lower part of the housing, while the float is made in the form of a ball with slots - water conduits located on its surface in mutually perpendicular planes (SU, copyright certificate No. 1618345. A1. M. class. ⁵ A 01 G 25/02. Dropper / G. G. Galifanov and V. V. Vavilov (USSR ) - Application No. 4601803/15; Stated 02.11.1988; Opub . 07.01. 1991 Bulletin. №1).

In this dropper, a ball-shaped float deserves attention. The dropper body does not require a clear fixation to the vertical. However, the water supplied by it is distributed on the surface of the irrigated area and does not provide moisture demand for the roots of plants. The essence of the claimed invention.

The problem to which the claimed invention is directed is to increase the accuracy of the distribution of artificial precipitation in the habitable horizon.

The technical result - improving the quality of irrigation, reducing the consumption of irrigation water, increasing the yield of agricultural cultures.

The specified technical result is achieved by the fact that in the known drip outlet comprising a housing with two interconnected chambers, an inlet and outlet, and a float valve located in the upper chamber according to the invention, a rod with grooves is made in the lower chamber associated with the injector on its surface along generators, in the grooves are placed wicks of either round or rectangular section; in the housing cover under the inlet, slots are made - drainage; the outlets of the upper chamber are oriented at an angle to the base of the lower chamber.

The invention is illustrated by drawings.

Figure 1 shows a drip outlet, a diametrical section.

Figure 2 - section aa in figure 1, the placement of wicks of circular cross section in the grooves of the rod.

Figure 3 - section aa in figure 1, the placement of wicks of rectangular cross section in the grooves of the rod.

Information confirming the possibility of implementing the claimed invention are as follows.

The drip outlet includes a housing 1 with two communicating openings 2 chambers 3 and 4, an inlet 5, an outlet 6 and a float valve 7 located in the upper chamber 3. In the lower chamber 4, conjugated with the injector 8, a rod 9 with grooves 10 on outer surface. The grooves 10 on the surface of the rod 9 are made parallel to its surface. In the grooves 10 are placed either wicks 11 of circular cross section or wicks 12 of rectangular cross section.

Outlets 2 of the upper chamber 3 are oriented at an angle to the base of the lower chamber 4. The injector 8 is hollow, has a pointed end 13 at the lower end. The upper part of the injector 8 is provided with an outlet 6 and a cavity. The diameter of the outlet 6 is equal to the diameter of the rod 9.

The housing 1 with the upper cover 14 is connected by a threaded portion 15. In the cover 14 of the housing 1, under the inlet 5, slots are made - drains 16. The upper chamber 3 is formed by the cavity from the cover 14 and the upper cavity of the housing 1. The lower chamber 4 is formed by the cavity of the injector 8 and the cavity under the jumper 17 of the housing 1. The housing 1 with the injector 8 is connected by a threaded portion 18. When properly assembled, the rod 9 abuts against the jumper 17 of the housing 1 with one end and the tip 13 of the injector 8. The tip 13 has a cavity 19 as a reserve tank. The injector 8 between the tip 13 and the threaded section 18 has a permeable sleeve 20.

Drip outlet works as follows.

A flexible sleeve inlet 5 on the cover 14 of the drip outlet is connected to the network of the drip irrigation system. Water under working pressure enters the upper chamber 3. Since the living section of the holes 2 is smaller than the cross-sectional area of the inlet 5, the cavity of the upper chamber is filled faster than it is emptied. The float valve 7 pops up and overlaps the main section of the hole 5. Through the slots - drainage system 16 there is a constant water supply to the upper chamber 3. From the upper chamber 3, water flows due to gravitational forces along inclined holes 2 to the bottom of the lower chamber 4. Placed around the perimeter of the rod 9 in grooves 10, the wicks 11 (12) absorb moisture and through the inter-fiber cavities, water flows smoothly with equal speed into the cavity of the injector 8. Most of the water through the porous sleeve 20 goes into the soil layer, moistening the root horizon and the roots of the agricultural plants. Unused moisture from the wicks 11 (12) accumulates in the cavity 19. During intensive evaporation from the soil surface and transpiration of the leafy stem mass, the wicks 11 (12) draw moisture to the permeable sleeve 20 and are consumed by plants.

The described set of essential features ensures the achievement of the specified technical result.
