Sprinkler installation

 

(57) Abstract:

The invention can be used in the field of irrigated agriculture, mainly in individual and farmlands for automatic irrigation. Sprinkler installation, connected to the mains or to be filled with water in another way, it consists of a tank with the outlet and a float valve, a supply tank connected to the irrigation system, the capacity of the evaporator with the float and metering device. The latter is located between the tank and feed tank. The dispenser is connected to the capacity of the evaporator by means of a flexible hose. When this float tank-evaporator with a lever, rocker with the load and the suspension is connected to the outlet of the tank. The invention provides a simplified design watering facilities, and thus reducing its cost. 2 Il.

The invention relates to irrigated agriculture and can be used for automatic irrigation garden, home sites, as well as for use on an industrial scale.

A device for automatic water supply in the irrigation network A. C. the USSR 657791, 24.07.77, consisting of recharge is recharge tank, and mechanically - with shut-off body of water, the device is equipped with an intermediate tank, hydraulically connected with the recharge reservoir and through the nozzle with the Executive tank.

This device is difficult, therefore has a high cost.

The closest to the technical nature of the claimed solution is A. C. the USSR 1558343 "Automated irrigation device, 08.06.88, including irrigation water, mounted on it a stop valve with hydraulic actuator and a valve associated with the sensor-evaporator, balanced by a counterweight, wherein to improve performance through control during growth and development of plants, the device has a storage capacity of the evaporator with the float and sensor-evaporator equipped with a regulator of evaporation, made in the form of a tape with a cut of alternating current, installed over the sensor-evaporator can travel and have the drive, made in the form trossoblochnoy system, which with one end of the tape is connected to the float tank-evaporator, and the other equipped with controlroom.

The disadvantage of this device is a great dual economy.

When designing the installation, the task was to simplify the design, and therefore reducing the cost.

The problem is solved due to the fact that the installation, consisting of a tank with a shut-off body in the form of a float valve, and a supply tank located below the reservoir, the dispenser is installed, connected by a flexible hose with storage capacity of the evaporator, while the dispenser is located between the outlet of the reservoir and a metering tank, and the float tank-evaporator with a lever, rocker with the load and the suspension is connected to the outlet of the tank. The positive effect is achieved due to the low cost of installation, rational use of water through drip irrigation, saving transport costs by automating the irrigation process.

The invention is illustrated by drawings, where Fig. 1 shows a General view of the installation: 1 - water supply 2 - float valve attached to the tank wall 3, 4-pendant with tube, 5 - arm, 6 - cargo, 7 - pull, 8 - float, 9 - dispenser, 10 - flexible hose 11 - capacity evaporator 12 - tank, 13-irrigation system, 14 - protective rod.

In Fig. 2 section I-I in Fig. 1.

In a specific example, the tank capacity 150 l made of steel with a thickness of 1 mm, a supply tank of the same material with a capacity of 120 liters of Irrigation is drip way through the main pipe made of polyethylene with a diameter of 42 mm, a length of 25 m and is attached to a fifty tubes of polyethylene length of 10 m, diameter 8 x 1 mm Diameter holes in the tubes of 0.5 mm Weight without irrigation pipes - 32 kg

Sprinkler installation, including irrigation water, the tank shut-off body in the form of a float valve, tank, tank-evaporator with float, irrigation system, characterized in that between the outlet of the reservoir and a metering tank is a pump, connected with a flexible hose with storage capacity of the evaporator, and the float tank-evaporator using a beam with the load, traction, and suspension, with a tube connected to the outlet of the tank.

FIELD: agricultural engineering, in particular, equipment for drop irrigation of farm crops.

SUBSTANCE: apparatus has cylindrical casing with inlet and outlet openings. Cylindrical casing has threaded covers and body. Valve and elastic cuff are movably positioned inside cavity of cylindrical casing. Apparatus is further equipped with additional cuff. Main and additional cuffs are provided with orifices. Valve is made in the form of concavo-concave lens arranged in spherical belt. Valve is manufactured from material having density smaller than density of water, in particular, valve may be made from cork of 0.2-0.3 t/m3 density. Valve is arranged in casing between cuffs and is adapted for alternating contacting through cuffs with projections oppositely arranged inside casing cavity. Projections are made in the form of spherical segments, with radius of spheres of segments being smaller than radius of spheres of concavo-concave valve lens. Difference between radii of projection sphere and that of spheres of concavo-concave valve lens is equal to thickness of elastic cuffs. Channels on apexes of cover and casing projections are extending in radial direction toward inlet and outlet openings.

EFFECT: increased efficiency and enhanced reliability in operation.
