Description

This invention relates to agricultural melnoricin and can be used for irrigating agricultural crops.

A subsoil irrigation system is known, including a water supply source, an alternate water supply device, a supply w, a pipeline, field distributors, head and end distributors and humidifiers. The system allows you to automate the process of pulsed water supply to humidifiers with various expenses 1.

However, in the known system, the reduction of water consumption to a constant value during the irrigation period is not achieved.

Closest to the present invention is a subsurface irrigation system comprising a water supply source, field distributors, sectional distributors, humidifiers, a multi-way valve for supplying water, a pipe connected kinematically to a multi-chamber hydrorelay, and a device for supplying air to the system 2.

The disadvantage of this system is low efficiency, due to the inability to supply water and air in accordance with a given need.

The purpose of the invention is to increase the efficiency of irrigation water use by uniformly changing the flow rate according to a given program.

The goal is achieved by the fact that in the subsurface irrigation system, containing a source of water supply, field and sectional distributors, humidifiers, a multiway valve on the supply pipe, kinematically connected with a multi-chamber hydrorelay, and a device for supplying air to the system, the holes in the multiway valve have different diameters, with the holes with the maximum diameter alternating in series with the holes of the minimum and average diameters, and the hydrorelay is kinematically connected with the device for ear system.

The inlet and outlet of the crane are located at an angle of 144 °, and the holes with minimum and average diameters are located relative to the inlet and outlet of, respectively, an angle of 72 °.

FIG. 1 shows the subsoil irrigation system, a general view; in fig. 2- kinematic connection of a four-way crane with a hydrorelay, cam and ratchet mechanisms; in fig. 3 - Hydro relay, cut.

The subsurface irrigation system includes a water supply source 1, a field distributor 2 with a four-way valve 3 installed on it to supply and shut off the water flow to the sectional distributor 4 and humidifiers 5. For a uniform change in water flow, the four-way valve 3 has three different diameters and angled at 72 ° holes (d |, 62, ds). The frequency of operation of the holes of the crane 3 is carried out using a pycamera valve 6, consisting of a feed tube 7, a working chamber 8 with an inlet 9 and a drain 10 calibrated holes mounted on the shaft 11. The gear ratio 2: 1 is produced by a gearbox 12, which drives the additional shaft 13 with the cams 14 and 15 mounted on it, the groove 16, the ratchet 17, the tooth 18, the latch 19, the dog 20.

 The air cylinder 21 and the air supply device are turned on and off by a rod 22, and a pulse tube 7 by a rod 23. A drain tank 24 is installed to collect water under the hydro relay 6.

The subsurface irrigation system operates as follows.

From the water supply source 1, water flows through the field distributor 2 to the four-way valve 3, opened in position di, sectional distributor 4, humidifiers 5, and through the inlet pipe 7 to the working chamber 8 (No. 1) of the five-chamber hydro relay 6. After a programmed period of time, water entering the working chamber 8 (no. 1) through the calibrated orifice 9 will reach such a level that the five-chamber hydro relay 6 will be out of balance and under the influence of the weight of water in the working chamber 8 will turn 144 °, turning at the same time Coy same angle four-way valve 3,

mounted on one shaft 11 with a hydrotrol 6. Through a gearbox 12 with a gear ratio of 2; 1, an additional shaft 13 is rotatably driven with a cam 14 mounted on it and ratchet mechanisms 17, turning them through 72 °. Having rotated 72 °, the four-way valve 3, the hydrorelay 6, the cams 15 and 16 are fixed by the tooth 18 and the lock 19 in a predetermined position, while the four-way valve 3, opened in the d2 position, provides

5 skip reduced water flow. The supply tube 7, according to a predetermined program, fills the working chamber (no. 2) with the hydrorelay 6, and the previous chamber (no. 1) is freed from water. After filling the working chamber (no. 2), the whole system is turned according to the above scheme to the da position, ensuring the flow of steady (constant) flow. After filling the working chamber (No. 3), the cam mechanism is in the position

J at which the rod 22 enters the groove 16, opening the access of air from the air cylinder 21 to the field distributor 2, and the four-way valve 3 at this time

blocks the flow of water from the water supply source 1.

After filling the working chamber (No. 4), the four-way valve 3 blocks the access of water to the field distributor 2, and the cam mechanism 14, pressing the rod 22, stops feeding the system with air.

During the fifth operating cycle, the field distributor 2 is briefly supplied with air from the air cylinder 21. At the end of this cycle, the ratchet mechanism 17 performs a full turn (from the beginning of the operation of the system) and is blocked by a lock 19, while the cam 15 pushes the rod 23, ensuring the water supply is shut off through the supply pipe 7 to the hydrorelay 6.

To carry out the next watering, it is necessary to release the latch knob 19 and the system will start working according to the above scheme (three times the flow rate change - continuous air supply - short-term air supply and blockage).

The proposed subsoil irrigation system automates the process of pulsed flow rate (time-varying) air according to a given program, eliminates water loss through filtration, expands the humidification circuit, reduces the saturation of humidifiers, and improves the water-air regime of the soil.
