The invention relates to a household specifically to the automation of irrigation of agricultural crops.

A subsoil irrigation system is known, which consists of a water supply source for the main and distribution tray system with water regulating facilities and irrigation pipelines with subsoil humidifiers l connected to them.

However, this system is difficult to operate and requires a lot of manual labor for irrigation.

Also known is an automated subsurface irrigation system, including a water supply source, supply distribution network, water supply controllers and humidifiers provided with feedback lines connecting them to the water supply regulator based on feedback from backpressure arising in the soil. as it becomes saturated with moisture {iQ

The disadvantage of this system is the high cost and complexity of operation due to the performance of a closed supply network and feedback pipelines, the length of which is not less than the length of the handles. In addition, information about the backpressure effect on one of the humidifiers extends to a sectional distributor serving a large group of humidifiers, which leads to uneven moistening of the irrigated area and reduces the quality of irrigation .:

The purpose of the invention is to simplify operation by self-regulating the duration of irrigation.

This goal is achieved by the fact that in the system the supply network is made in the form of trays with cascade compartments, and the humidifiers are equipped with siphon / tips, mounted in the inlets and on-mix inlets, which are higher than the transit level, have float drives located in symmetrically arranged pocket cameras equipped with inlet sifais / communicated with the bay of the lower compartment AND drain siphons / communicated with cherbz of charge-pipe. on the cover.

figure 4 (drain siphon with charge tube); figure 7 - section GG in figure 4 (inlet siphon).

The subsoil system includes, (FIG. 1) a water supply source 1, a trunk 2 and a distribution 3 tray network with automatic machines of 4 level, irrigation trays 5. Supply network with cascade compartments 6 formed by water supply regulators 7 and subsoil humidifiers 8, equipped with siphoinley tips 9, mounted in irrigation trays 5 (Fig. 2 and 3).

The siphon tips 9 consist of two coaxial pipes, the outer of which has a float 10, and the inner pipe has an adjustable opening 11 and is a continuation of the soil humidifier, with the adjustable opening located above the transit level of water in the irrigation chute by the value of its velocity head.

The water supply regulators 7 in each, cut off except the first one adjacent to the distribution tray, are made in the form of slamming flat rotating panels 12, hingely hanging on the horizontal axis 13 to the collecting wall 14, and have / counterweight 15 rigidly fixed by axis 16 on the rotating panel The float drives of which are 17 are hingedly mounted on a horizontal axis 18, which is falsely connected with a rotating shield, and are located in pocket cameras 19. Regu: l tori. water supply of the first compartment (Figures 4 and 5J are made in the form of segment shields 20 with a horizontal axis of rotation 21, balanced by a counterweight 22, and have floats 23 located in pocket-type float chambers 19. Automatic float chambers 19 (Fig. 6 and 7 ) communicate with the downstream bay of the inlet siphon 24 and drain the siphrinum 25, the cavities of which through the charging tube 26 communicate with the bay of the adjacent compartment, and the charging tubes are made with hydraulic locks 27.; Avts 1atiz1 The system of subsurface irrigation works as follows s at once ..,: .-- ..,. -,.

In the absence of water in the system, and, consequently, in the float chambers 19, the flat rotary shields 12 of the retor feeds of the water supply are in a horizontal position (position 1 in Fig. 3) due to the moment mass of the counterweight 15 and the floats. e. fully open; the segment shields of the first 20 compartments due to the action of the weight of the counterweight 22 and the Floats 23 from the moments are also in the open position (POLO

II) - figure 5).

When supplying the calculated flow rate to the mains network 2, water with the help of automatic machines of level 4, evenly distributed between irrigation trays 5 / passes through all their compartments b, without entering the siphon heads 9 of the subsoil humidifiers, as the adjustable holes 11., The tips are The transition of the transit water level in the irrigation tray on the value of its velocity head. After reaching the deaf end of the tray, its end compartment is filled, in which the water level 15 rises and becomes sufficient for siphon caps 9 to work, through which water enters the humidifiers 8 and is further absorbed into the soil. As the soil becomes saturated with moisture jQ, the rate decreases. In irrigation water and in the humidifier 8, residual water pressure increases.

As a result, in the inner tube, the cap 9, the elongator 8, the humidifier 8, will start to turn itself up neo1: a1) and the python consumption will fall, i.e. In the head of each humidifier, water supply is self-regulated depending on the moisture saturation.

: The intensity of the reduction in supply to the dog; ay (humidifier is determined by the rate of saturation of the soil, which is in the zone of influence of the humidifier. This eliminates the possibility of: 35 uneven moistening of the irrigated area.

Thus, siphon tips 9, installed in irrigation trays and connected to the subsoil humidifiers 40., are self-regulating flow rates that allow autolinkers to reduce the flow to the humidifiers.

as the soil is saturated with moisture. - The use of siphon as a self. 45 of the regulator became possible due to the dependence of the siphon flow rate on the change in pressure in its internal pipe, which is a continuation of the humidifier.

As the water level of the humidifier compartment decreases, the water level in the end compartment of the irrigation tray begins to wave, as a result of which the inlet siphons 24, which float 5 kgmers 19 of the water supply regulator installed — at the beginning of the end compartment — are activated, the floats will float and the action of buoyancy force flat, rotary shields 12 are rotated against the 60-hour hand around the axis 13 and, seizing, overloading the water supply to the end compartment, thereby creating conditions for filling the penultimate compartment with water conjugated with kontsevm.5

The volume of water remaining in the end compartment is gradually absorbed by the siphon caps of the humidifiers and absorbed into the ground.

Watering from the penultimate compartment occurs similarly to that considered. At the same time, with an increase in the level of water in it, the water will begin to flow both through the inlet valve into the float chamber of the automatic shutter located in the head of the compartment and through the charging tube 26 into the drain siphon 25 of the automatic shutter located at its end. As a result, the drain siphon 25 will charge and empty the float valve, and the automatic shutter at the end of the penultimate compartment will be in the closed position only due to the effect of hydrostatic water pressure on the flat rotating shield 12 from its upper reach.

Making a charging tube with a hydraulic lock 27 (Fig. 6) prevents air from entering the cavity of the siphon 25 when the charging tube is operated with an incomplete section. This ensures that the siphon is turned on reliably and the float chamber is completely emptied.

After stopping the supply of water to the penultimate compartment caused by the operation of its head vatvor and lowering the water level due to suction of humidifiers with siphon tips of humidifiers, the flat rotating shield 12 at the end of the penultimate compartment under the action of moments from the counterweight mass 15 and floats again takes a horizontal position (position D figure 3), i.e. fully open with.

Thus, as the compartments empty (except for the first compartment adjacent to the distribution tray), the davors installed at their ends automatically open, thereby preparing the irrigation tray for the next irrigation cycle.

Watering from the first compartment occurs similarly to that considered, with an increase in it, at smooth water will begin to flow through the charging tube 26 into the drain siphon 25 of the automatic shutter with a balanced segment shield located at the end of the first compartment (Figures 4 and 5).

As a result, the drain siphon air will empty the float chamber, while under the action of the masses from the cash register float 23 and the vertical hydrostatic pressure and the segment UUIT from the jero side will open (rise up), the water level in the compartment will decrease, watering from the first compartment stop and the water transits

it will again start to flow into the end compartment of the irrigation tray, i.e. The irrigation cycle will automatically start.

Thus, the execution of automatic aatvrr of the first compartments in the form of segmented balanced shields and automatic shutters of all. After a number of interceptions - in the form of slamming flat rotary shields

ensures continuity of irrigation cycles of the system.

The proposed subsoil irrigation system makes it easier to exempt the plague by automatically regulating the irrigation and to increase the effectiveness of the subsoil irrigation by eliminating uneven moistening of the irrigated area.
