Essence: in sredneshirotnoi sprinkler apparatus having a multi-directional trunks 3, the rocker 5 is installed a rotary deflector 10 with swivel-rotary jet plate 12 facing the nozzles 4 of the shafts 3. Water jet from the nozzle 4, getting on the deflector 10 and the plate 12, separated from their edges in the form of a fan at right angles with great speed. At the location of the sprinkler apparatus in a suspended form the deflector 10 can raise the water jet emerging from the nozzle 4 from - 30 to +10 to the horizon, while maintaining the optimum angle of ejection of the atomized spray and the structure of the rain. 4 Il.

The invention relates to agriculture, namely, irrigation technology, and can be used in sprinkler systems.

Known srednesrocnye sprinkler apparatus circular steps, including a housing with a Central shaft inside the two side of the trunk with nozzles pointing in opposite directions, and the rotation unit of the apparatus, consisting of a rocker arm with a reactive blade on one end and protivovesa the rotation of the rocker arm, perceiving his pulse beats with the range of angle of rotation of the apparatus for 2-4aboutfor each hit, with the angles between the axes of the holes sidetracks nozzles and the horizon is approximately in the range of 30about(Reference mechanization of irrigation. Edited by B. G. Stay. Moscow, Kolos, 1979) similar.

This device has many disadvantages. First, the angle of the axial line of the nozzle horizon is constant and very large. It creates rain with a large vertical windage, which leads to large losses to entrainment by the wind from the irrigated area of the field and evaporation, which in turn leads to unsustainable consumption not only water and significant amounts of energy (the flow of water through the irrigation system from the source of supply to the sprinkler apparatus and the transformation of water in the rain), but also to reduce the installed irrigation rates, and hence the yield of the irrigated field. Secondly, the openings of the nozzles (nozzle) from all sizes of vehicles at the exit of the jet of water into the atmosphere cylindrical, with a diameter more than 5 mm, for Example, sprinkling machines "Fregat upper stage DM-454-90" diameter of the nozzles reaches 11,9 mm Such cylindrical oanoe dust) to diameters, exceeding 2-3 mm. Small drops easily carried by the wind and swell, not reaching the soil, and large are the dynamics of the fall 6, which destroys the soil structure and turns it into dust condition, reduces fertility, causes environmental harm. Thirdly, this type of apparatus cannot be applied in a suspended position, for example on the rod, the more closely, for example, not higher than 1 m from the irrigated field surface, for example, in order to reduce losses of rain on the entrainment by wind and evaporation. Jet (suspended) 't have time to break down in the air and will hit the ground at an angle 30aboutto the horizon and how the hoses to wash away the soil, damage (to lay on the ground) plants. Fourth, the disadvantage of this device include the following. The spring mechanism of rotation requires individual selection by the force of the return beam after its swirling jet shovel from the jet and the force of impact of the beam on the rack. You want every stroke of the rocker arm provided a rotating apparatus for 2-4about. This deficiency leads to the fact that the factory machines have them in the rotation mode, trouble-free operation, each individually. Because of this labor-intensive in Istria, refuse to work normally, than violate the timing of irrigation (reliability mode), reduce the yield.

Known srednesrocnye sprinkling apparatus of the circular steps that are different from the similar fact that the angles between the axial line of the nozzle and the horizon can be chosen smaller than the 30aboutto the horizon in the manufacturing process of the limit 5-30about. Thus the apparatus can be made such that it can be operated as in a normal standing position platform stands the mechanism of rotation of the top and inverted 180aboutsuspended (ed.St. N 1498434, 1989) prototype.

Significant disadvantages to this device. After manufacture, such as wheels made of special bronze, the centerline of its nozzles to form a horizon of only a single, well-defined angle of the limit 5-30about. In this case, if the apparatus is designed for a staff position, and the angle to the horizon, for example, +15abouthe being flipped "upside down", will give the angle is negative, equal to -15aboutto the horizon. And waterer will not be able during operation change this unsuitable angle and use the device in a suspended rod position. In addition, the device inherent and riometer, hence the heterogeneous structure of rain drop size, the presence of large drops, the spring mechanism of rotation and apparatus require individual selection.

The purpose of the invention, the reduction of losses of rain on the entrainment by wind and evaporation, improvement of its qualitative characteristics, increase process reliability rotation of the device in the specified mode, which is feasible by selection in the course of its operation the optimum angle of emission of jets of water into the atmosphere, with the simultaneous expansion of these jets and their partial use in the using of the mechanism of rotation.

This objective is achieved in that on one of the rotating parts of the machine, for example on the top floor stands mechanism of rotation fortified Duplessy bracket, which is located approximately in the plane of the centerline of Central and laterals with nozzles, the ends of which are outside of the rotating parts, and at each end of the reinforced swivel / tilt, for example by means of a hinge and adjustable along the length of the T-shaped pins, vent, a working surface facing the stream of water emitted by a cylindrical hole (nozzle) nozzle. While the working surface of the deflector can be installed kanee, for example 5-10 mm, and in working across a stream at any acute angle limit of 40 +30aboutto -10aboutto the horizon. Moreover, at the end of the working surface of the deflector is approximately perpendicular to it, reinforced articulated swivel jet wagotreagma plate work (lateral) surface which can form with the direction of the jet of water is different (adjustable) angles in the plane of rotation of the apparatus and to reflect part of the jet in the direction against its rotation. Through this jet plate, by changing (regulation) of the corners of her with the jet direction almost from the first spring of the rotation mechanism made according to the standard, achieved the desired rotation of the apparatus for the shock rocker about 2-4 hoursaboutor other desired angles.

Such sprinkler apparatus can be used in a suspended position on the rod down platform stands mechanism of rotation. In this case, the deflector bracket can raise the water jet emerging from the nozzle tips from -30aboutto +10 to the horizon. Thus, the apparatus is suitable for use in standard and inverted 180aboutthe provisions and waterer gets the opportunity to pick up during exploraton (40about), at the same time to regulate and reliability of rotation of the apparatus and to receive a jet of water emerging from the apparatus into the atmosphere is not cylindrical in shape and thick, and flat thin film, giving smaller raindrops with his best structure.

In Fig.1 schematically srednesrocnye sprinkler apparatus, a General view in normal position; Fig.2 is a top view of Fig.3 diagram of the emission of a jet of water from a cylindrical nozzle orifice, its collision with the working surface of the deflector and the jet plate Assembly of the jet with the edges of the baffle, collisions with air and the formation of rain, side view; Fig.4 is the same, top view.

Srednesrocnye sprinkler apparatus includes a housing 1, the Central (vertical) tube (2), two side diametrically-located shaft 3 with the nozzle 4, with the angles between the axes of their openings and the horizon within the 30aboutnode of rotation of the arm 5 with one two jet vanes 6 on one or two ends, two front 7 that restricts the rotation of the rocker arm 5, rigidly connected with the side holes 3, a return spring 8 and to perform the intended purposes the device has on one of the rotating parts, for example on the top floor of the "P" stands mechanincal and sidetracks nozzles, ends of which are outside of the rotating parts, and at each end, for example, by a hinge "Sch" and adjustable along the length of the T-shaped pins 11 secured to the deflector 10, the working surface of which is located on the bottom and facing toward the cylindrical (form) of the water jet, emitted a cylindrical bore of the nozzle 4. While the working surface of the deflector 10 may be installed in the off position parallel to the nearest generatrix line of the jet and at a short distance from it, such as 5-10 mm, and in working across a stream at any acute angle of limit 40about+30aboutto -10aboutto the horizon. Moreover, at the end of the working surface of each deflector 10, approximately perpendicular to it, reinforced articulated swivel jet plate 12, is pivoted to work against the direction of rotation of the device "NCA" (top view counterclockwise) to the desired acute angle from the projection on the working surface of the baffle centerline of the nozzle orifice 4. The position of the deflector 10 sh-01 outside; W-02 turn the water jet and rain in the horizontal plane; sh-03 angle -10aboutfrom horizon (when the wind speed is greater than 10 m/c).

If APPA baffle 10 and inclination them the cylindrical jet, emerging from the nozzle orifice 7 is changed from -30aboutto +10aboutto the horizon.

Srednesrocnye sprinkler apparatus operates as follows. Water under pressure passes through the Central shaft 2, laterals 3, the nozzle 4 and in the form of a cylindrical jet "With" emitted into the atmosphere. If the device has an arm 5 with a single jet blade 6, which is inherent in analogue, Fig.1 (prototype, ed.St. N 1498434, yoke with two blades), then part of the jet hits the core part of the scapula, and from it is discarded in the direction of rotation of the apparatus, i.e., clockwise. From the reactive force of this part of the jet vane 6 is discarded at an angle of 15-30aboutagainst the spacecraft rotation (counterclockwise), the rocker 5 vvodit (twists) the spring 8. Jet, force of pressure, bypassing the blade 6, hits (simultaneously from both nozzles 4) in the operating surfaces of the deflectors 10, spreading them in a thin layer and separated from their edges and the edges of the jet plates 12 respectively at angles and with great speed in the atmosphere. Colliding with air, thin jet of atomized form rain in the form of a fan with a width several times greater than the diameter of the cylindrical jet. This CPE is sdwa reactive power, aimed at turning apparatus in the direction of rotation is clockwise. At the same time cocked (twisted optional) spring 8 returns with the acceleration of the rocker arm 5 to its original position, produces a shot with two uprights 7 of the mechanism of rotation with different parties and together with the force of reaction of the water dropped from the plate 12, the pulse 2-4about, rotate the device clockwise. After that, the processes are repeated continuously and at 90-180 beats rocker apparatus makes a complete revolution around the axis of rotation and deflector 10 and the plate 12 as many times pulses reflect flat thin stream into the atmosphere, in which the collision she turns into rain low intensity, uniform structure of droplets, whose diameter is less than the thinner the layer streams running down from the working surface of the deflector 10. While rain can be obtained with reduced vertical sail, with higher and more resistant to wind efficiency through the optimal angle for the devices used in their normal position, and, especially, in inverted 180aboutposition by moving it up and down and not higher than 1 m from the irrigated surface of the field to get them "ivydale test apparatus at the factory and conditions.

The present technical solution in comparison with analogue and prototype will not require the high cost of its implementation, but will yield significant economic benefits. In particular, will reduce wasteful consumption of water and energy resources, stabilizes and raises irrigation rates and yields of irrigated fields. And, no less important, this solution will provide ecological usefulness atomized with the best structure the rain will be less likely to destroy the soil structure, fertility of the earth.

Moreover, this solution can be used not only in the manufacture of new devices, but without great difficulties when upgrading devices purchased by the consumer, i.e., in operation.

It is obvious that we cannot ignore and environmental usefulness of the rational use of soil fertility the main wealth of any nation.
