Abstract

The invention relates to agricultural machinery and can be used to release water from underground irrigation pipelines when irrigating crops. The goal is to increase reliability in work. The outflow of the underground irrigation pipeline consists of a vertical nozzle 2 mounted in the pipeline 1 with a check valve 3 and a stepped body 4 narrowing upwards. The check valve 3 is made in the form of a cylindrical cup and installed in the upper part of the body 4, also made in the form of a cylinder. The outlet is equipped with a lock of the upper position of the valve 3, made in the form of a magnet-ferromagnet pair. On the lower side of the housing 4 on the nozzle 2, using a yoke 7, a cup-shaped diverting deflector 8 is installed. When the water rises, the valve 3 moves upwards, opening the outlet to the water, while its position at the top is fixed by rings 5 and 6 of the magnet-ferromagnet pair. 2 Il.

The invention relates to agricultural machinery and can be used to release water from underground irrigation pipelines when irrigating crops.

The purpose of the invention is to increase reliability in operation.

FIG. 1 given water outlet, closed state; in fig. 2 - the same operating condition.

The outflow of the underground irrigation pipeline includes a vertical pipe 2 installed in the pipeline 1 with a check valve 3 and a stepped body 4 tapering upwards. The check valve 3 is designed as a cylindrical cup, which is set bottom-up. The body in the upper part is also made in the form of a cylinder with the possibility of telescopic movement and is equipped with a lock of the upper position, made in the form of a pair of rings: a magnetic ring 5 on the lower part of the valve 3 and a ferromagnetic ring 6 at the bottom of the cylindrical part of the body 4. On the lower side of the body 4 on the nozzle 2, a clamping deflector 8 of a cup-shaped form is installed with a clamp 7.

The outlet works as follows.

In the non-operating state, the check valve 3 is in the lower position and closes the inlet to the vertical nozzle 2.

When water is supplied to the pipeline 1, it enters the pipe 2 and, lifting the valve 3, which, under the pressure of water and the mutual interference of the magnetic ring 5 with the ferromagnetic ring 6, is fixed in the upper position, pours down between the housing 4 and pipe 2 and further, the shock

The reflector 8 is turned 180 ° and, penetrating through the thickness of the soil, enters the surface of the soil in a furrow or strip. Upon termination of the water supply, the valve 3 under its own weight drops down onto the nozzle 2 and closes the entrance to it. The mass of the sink from the funnel erosion, in the presence of air under the hood-housing 4 does not go under it, and in the absence of air does not penetrate into the vertical nozzle 2, as it is securely closed.

Adjusting the flow of water is usually carried out when changing crops of continuous sowing to tilled crops and vice versa, since in this case the value of the flow of water decreases or increases. In order to change the water flow through the outlet, it is previously excavated and, loosening the clamp 7, move the reflector 8 up or down, set the required clearance between the reflector 8 and the lower part of the housing 4.
