Abstract

The invention relates to agriculture and can be used to automate the irrigation of orchards and yearlings. The purpose of the invention is to ensure the operation in automatic mode and reduce energy costs. The polyEz term indicator (CSP) works automatically from the anergy of the water that is supplied for evaporation, adjusts the irrigation time for effective precipitation, which will be released during the irrigation period. In the vessel 1, a hollow cylinder 2 is installed, on which floats 3 and 4 are placed. The floats are kinematically connected through the sector with fingers 36 and 37. On the rod 7 there is a driver 13 for setting the SCF to a predetermined command command threshold. The float device 45 gradually, returning to evaporation, supplies water from the tank 1 to the evaporator 47. After water flows through the pipe from the tank 1 to a certain level, the float 3 actuates the sector. The finger 36 presses the switch 38 of the additional organ, and the finger 37 lifts the water inlet valve 39 into the container 1 at the outlet of the pressure network. After raising the level to the preset mark, the float 4, acting on the sector, leads the fingers 36 and 37 to the initial position. I zp f-ly, 3 ill. i (L

The purpose of the invention is to ensure the operation of the irrigation time indicator in automatic mode and reduce energy costs.

FIG. 1 s.he.metrically shown irrigation time indicator, section; in fig. 2 and 3 of its details in collaboration.

The water irrigation time analyzer contains the measuring tank 1, inside which the hollow cylinder 2 is vertically mounted. It serves as guides for the 3 and 4 concentric floats 3 and 4 in the opening in the bottom of the tank 1, and 5 in the upper part of the wall cylinder 2 is placed rod 7 (Fig. 2). At its lower end, the cross member 8 is fixed with the possibility of rotation, the ends of which have longitudinal slots in the wall beyond the cylinder 2 and are rigidly connected to the float 3.

On the part of the rod 7 is threaded. The rod 7 is passed through a hole in the cover 9. A nut 10 and a coupling 11 are screwed on it, the nut is placed in the cavity of the cylinder 2, and the coupling is on the level of the cover 9. On the outer side, a rail 12 with a scale and a pointer is attached to the coupling 11. At the upper end of the rod 7 is installed the crank 13.

In the upper part of the hollow cylinder there is a clutch assembly, which includes, in addition to the nut 10, two pairs, directed 3 and rigidly connected to the cover 9 of the brackets 14 and 15. On the axles inserted into the sko.zhnie holes 14 and 1.5, Disks 16 and 17 with a removed segment are free to spacing. The disks 16 and 17 with the help of studs 18 and 19 are movably connected to the nut 10. In addition, in the cavity of qi: 1, 2, the load 20 is installed with the possibility of vertical; 1 11 about movement (Fig. 2). The load 20 has through) the first axial hole 21 for accommodating the rod 7, in the upper part two openings 22 and 23, in the middle through diametral cut-out 24, and in the lower part - hangers 2.5 and 26 extending through longitudinal slots in the steppe limits hollow qi.

A casing 27 is attached in the upper part of cylinder 2.

As a result, a new correction of the threshold is performed, if necessary, after one year.

Then water is supplied to the irrigation network. Water through valve 39, which is raised above its saddle, enters the dimensional capacitance 1, from where the float tube 44 and tube 46 enters the evaporator 47 through pipe 5. After filling the evaporator to the level of drain pipe 48, the float device 45 closes pipe 5 and the water begins to fill the tank I. First the float 3 with the rod 7 rises up to the stop, then the float 4. Having reached the shoulders 25 and 26, it will begin to lift the load 20. When the lugs 22 and 23, having overcome the lifting force of the float 3, the top edge for a moment turn the disks 16 to 17 and enter with them to the clutch, the load 20 by the lower edge of the notch 24 will lift the lever 43 and turn the latch 42, freeing the sector 29. Under the force of gravity, the sector 29 will pick up the initial position shown in FIG. 2. The fingers 36 and 37 will enter the cavity of the casing 27, releasing the switch 38 of the signal to the actuator,; 39 l valve - is in its socket. The water supply to the measuring tank 1 will stop. During the subsequent time, the float device 45 will gradually release water from the measuring tank 1 to the evaporator 47, evaporating the vapor.

Accounting for precipitation in determining the period of time, beer is as follows.

Since the water level in the evaporator 47 is maintained by the float device 45 equal to the threshold of the opening of the drain pipe 48, when precipitations and an equal amount of water flow out of the evaporator 47 and the evaporation data for the inter-irrigation period will not be distorted} 1y. The neck 51 of the pipe 50 is above the bottom of the rain gauge so that if the precipitations are insignificant and do not have a significant effect on the soil moisture of the computational layer, they will remain in the rain gauge 49, and then the evaporation will evaporate. The cross section of the neck 51 of the pipe 50 is calibrated so that the rainfall, the deposition rate of the soil absorbency, does not fit into it and will be removed from the rain gauge 49 through the drain nipple 52. During the rain, swell 1, and. Matter, reduce the throughput capacity of the inlet 51, pipe 50, thereby simulating a gradual decrease in the soil absorbency. If the precipitations are not heavy, heavy, or they have been harvested after irrigation, then moisture can penetrate deeper than the calculated soil layer, where it will remain inaccessible to the plants. To account for the dryness in the measuring tank 1

the drain pipe 6 is installed on such a b1-cell, in which the volume of water in the working part of the measuring tank I is equivalent to the volume that is able to hold the layer of the soil soil of the rated capacity, i.e. volume through pipe 6 of merged water of equivalent, 1tenten loss on deep seepage. Thus, the irrigation time indicator only takes into account the effective rainfall, and by studying the evaporation and runoff from the pipes 6.48 and 51, it is possible to evaluate the flow and waste items of the water baseline of the metering soil layer.

After evaporation and: evaporator of a predetermined volume of water, the floats 3 and 4 are empty. Under their weight and their own weight, the rod 7 adopts the lower one, the survival (Fig. 2), turning the disks 16 and 17 so that the cut-off planes of the segment stand vertically. The openings 22 and 23 will come out of the clutch with the disks 16 and 17 and the load 20 will fall. Pad, the weight of the side edge of the cutout 24 will turn the sector 29 in the direction of clockwise rotation. At the same time, the finger 36 will pop out and press on the switch. 1 38, make a rim, and the finger 37 will lift the water inlet valve into the measuring tank 1. Simultaneously, the latch 42, under the action of the weight of the lever 43, rotates about its axis and, entering the cutout 31 of the shank 30 29. Then the described cycle is repeated.
