Description

 The invention relates to agriculture, in particular to irrigation equipment, and can be used in surface irrigation systems.

 Known tray irrigation networks in the form of irrigation installations, tray irrigators, irrigation trays, irrigation systems, and, in particular, an irrigation tray consisting of a number (network) of tray compartments having openings in the bottom part, equipped with fittings and external flexible irrigation pipes, with a mechanism for driving these tubes into operation for irrigation and shutting down - stopping irrigation (AS N 497376, Bull. N 48 from 12.30.75. Analog).

 A significant drawback of this technical solution is the complexity of the design of the drive mechanism of irrigation nozzles, grouped by a perforated pipe, filled with water through a special valve for lowering and turning them on, and released from water through perforations, for raising and turning them off.

 Known tray irrigation network under the name "device for irrigation", which also includes a tray sprinkler with external water outlets and coupled kinematically with them, the mechanism of their rise (shutdown) and lowering (inclusion in the work). This device was the development of an analogue (A.S. N 1194963. Bull. N 44 from 11/30/85 Prototype).

 A significant drawback and prototype excessive design complexity and, of course, the high cost of manufacture and operation.

 The purpose of the invention is to simplify the design and cost reduction of production and operation.

 This goal is achieved by using water as a means of taking water from the tray, transferring it to one or both sides of the tray, to single or group water outlets-dispensers, as well as to another, sequentially or parallelly placed tray, bellows (corrugated) tubes installed inside the tray their base (lower part) into the fittings of its bottom part, and the water intake head (upper part), equipped with a tilt lever, if necessary, in a certain order are interconnected in groups by a flexible thread (stainless steel breech, etc.), while the top of each lever of the bellows head is attached to the thread with the possibility of regulating the position or release from it, the inclusion of the bellows (group of bellows) in the work of certain norms and the watering time is set by a measured capacity such as a water clock, with calibrated a consumable nozzle (dropper nozzle) in the bottom part, the container is suspended at the front end of the thread passed through the block in the head of the tray, and the bellows, group of bellows are switched off from work by automatically counterbalancing the capacitance and, suspended at the rear end of the thread, passed through the block at the end of the tray, outweighing the container after it is freed from a predetermined quantity-norm of ballast water, while the mass of the tare of the measured capacity is less than the mass of the counterweight by an amount sufficient to remove all the bellows from working position, set to initial.

 To turn the first tray of the irrigation network into a means for transporting water from the water supply system to the next tray, installed in series or in parallel, and automatically turn on the next tray, the previous one has an overflow bellows, the head lever and the head of which when turning off the irrigation bellows are tilted in the opposite direction under the action of a collapsible washer mounted on the thread, the head is insulated while the water through the connecting pipe, with the shut-off mouth open on it oystve flows into the subsequent tray that irrigation bellows pre-set to act, since it is, like the first, is charged simultaneously with measuring cup, but with the amount of ballast water in it twice that charges the first. In this case, the third, fourth, etc. trays will be included in the work similar to the second, provided that the amount of ballast water in each subsequent measuring tank is greater than the previous one by the value of the first multiple of the tray number, and all irrigation bellows are included in advance the working position and locking devices on the pipes connecting the trays are open.

 In FIG. 1 schematically depicts the tray of the Lotos trough irrigation network in the initial position in the transverse section along the irrigation bellows; in FIG. 2 is the same, in longitudinal section along AA, FIG. 1; in FIG. 3 irrigation network "Lotus" in the context of the working position of the first tray.

 The chute irrigation network consists of one or a group of chute irrigators, including chute 1, having a set of water outlets, each of which includes a nozzle 2, mounted in the hole in the bottom of the chute, a square (for pouring water on one side of the chute) or tee 3 (for pouring water on both sides of the tray) with a plug 4, an extension pipe 5, a water distribution pipe 6 with fittings 7, a thin-walled (elastic) pipe that extends toward the end, a water flow velocity damper 8, an elastic bellows (corrugated) pipe 9 with a water intake cap 10, equipped with a lever 11 rigidly connected to it, the apex of thin elastic thread 12 connected into the necessary groups, thrown by the ends through blocks 13 and 14, respectively loaded by hanging in the initial part-measured capacity 15 (in the form of a water clock) with a nozzle calibrated by the water flow rate - a dropper 16, and in the end part a counterbalance 17. To supply water to tray 1 of the first sprinkler from the water supply system (pump, well, earthen, concrete economic or inter-farm canal, located above, in terms of level, lot 1, etc.) has a pipe 18 with shutoff valves 19. For water bypass from the first tray and any previous to the next, each previous one has a bypass bellows 20, included in the work (by water bypass) with a washer 21. For transporting water pipe 22 with stop valves 23.

 The tray irrigation network operates as follows (Fig. 3).

 In the calibrated capacity 15 of the first tray, a certain amount of filtered water is poured, as well as the second, third, etc. trays, but in quantity, respectively, in two, three, etc. times bigger. Capacity 15, becoming heavier than the counterweight 17, drops to a certain limit. The thread 12, acting on the levers 11, tilts the water intake heads 10, bending the bellows 9. The water from the pipe 18 at a certain (normal flow rate of all outlets included in the operation) opening of the valve 19 from the filled tray 1 passes through the head 10, pipe 9, tee 3 , pipe 5 (in two pipes 5, if plug 4 is removed), a distribution pipe 6, from which flows through the fittings 7 and dampers of flow rate 8, for example, to the bottom of the furrow D. B, without filling the ridges of the furrows GB. As soon as the mass of the measuring container 15 due to the outflow of water through the calibrated device 16 becomes less than the mass of the counterweight 17, the latter begins to lower, the thread 12 by the levers 11 will raise the heads 10 of the irrigation bellows from the water 9. At the same time, the bellows will be free of water, float and water under the first tray of the irrigation network will automatically pause. Together with the irrigation bellows and water outlets being turned off, the thread 12 with the washer 21 will turn the bypass bellows head 20 for the lever and the water from the first line tray that becomes transporting it will flow through pipe 22, open shutoff valves 23 into the second tray sprinkler (second line tray), which will start working the same way as the first chute irrigator the first line chute worked.

 It is quite obvious that the proposed Lotos irrigation network will find the widest application in the near future, as it solves the urgent problem of a shortage of material, technical, energy and monetary resources, which is especially felt by CIS farms irrigating cotton fields, orchards, vegetable gardens and especially on the terraces of rolling hills.
