(57) Abstract:

Use: irrigation technique, namely in sprinkler systems. The inventive srednesrocnye sprinkler apparatus includes a housing 1, a Central shaft 2, two side shaft 3, with the angles between the axial lines of their holes and the horizon of the 30o, site rotation, two racks 7, rigidly connected with trunks 3 below and between the upper landing, two plate profile deflator 11 mounted narrow sides directly on the bodies of the nozzles 4. Working surfaces of the baffles 11 are constant angle10 - 20obending away from the centerline of the nozzle holes and alternating bending angle of inclination20 - 20ojust vent, and the sum of angles1and2sets the working surface of the end of each deflector is approximately horizontal position, with a deviation in the range of 0 to 10oand additionally end edges of the vent width of about 0 to 5 mm have angles3bend, depth and width edges, decreasing as the distance from the middle of struisbaai part of the deflector 11. 6 Il.

The invention relates to agriculture, namely, irrigation technique, and may be used which includes a housing with a Central shaft inside two sidetracks long and short, ending sprinkler nozzles facing in diametrically opposite directions, to the buildings which is welded to the bracket with dividers water jets and a host of rotation of the apparatus, consisting of a rocker arm with a reactive blade on one end and a counterweight at the other, recoil, and two pillars fixed on the lateral trunks, limiting 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 and also the openings of the nozzles nozzles and horizons about within the 30about.

This device has a number of disadvantages. First, the angle between the centerlines of its sidetracks, too nozzles with the horizon, is very large. This creates a rain overly long range, large vertical sail, which leads to large losses its efficiency to entrainment by the wind from the irrigated area of the field, stretching sails in the horizontal plane and its evaporation, and in General to the waste of not only water, but also a considerable amount of energy resources for pumping water for the irrigation system to the apparatus and p. irrigated fields. Secondly, all sizes of devices, openings (nozzles) nozzle at the exit of the jets in the atmosphere cylindrical, with diameters of, for example, the DM-454-90 "Frigate", up to 11.9 mm Such cylindrical holes, despite the use of plates with dividers jets form in the air narrowband, with a large instant low intensity rain, rosemary on the structure of the droplet size, Amorosi (spray) to diameters greater than 4-5 mm Small drops easily takes the wind, they do not reach the irrigated surface of the field and give in sediment rain with larger drops, with greater concentration of salts in comparison with the source water intake. While large drops destroy the soil structure, exceed its soil lumps in the powdered sterile condition than put irrigated environmental harm. Third, these devices cannot be used in an inverted position, for example hanging on the rod, especially at altitudes of no more than 1 m from surface irrigation, which requires the technology of subsurface irrigation in wind irrigation zones. In this position the sprinkler nozzle at an angle 30aboutto the horizon working under the pressure of 4-6 atmospheres will beat in irrigated surface fields as brandstater. The spring mechanism of rotation of the apparatus is not always and not even any target, provides the necessary force of impact of the beam on the rack and turn the machine is not in the desired angle for the shot, equal to 2-4about. And depends on the intensity of the rain layer of sediment per minute, i.e., again the environmental quality of irrigation. Sometimes, and often, when the machine actually stops spinning and then there is erosion of the soil. Need to stop sprinkler replacement of the spring.

The purpose of the invention to simplify the design, reduce metal consumption, the complexity of the manufacturing process and improving the quality of the rain.

This objective is achieved in that the baffles, allowing you to get the rain under the angle of emission of jets of limit 010aboutthe horizon is fixed by extremity and the l-shaped brackets directly on buildings (nerezinovym parts) sprinkler nozzles. Thus reduced and the size of the baffles, and instead of reactive plates, reducing the quality of the rain, to generate reactive power, which helps to rotate the apparatus and to adjust the angle of the pulse rotation within 2-4aboutfor every stroke of the rocker arm on the rack mechanism of rotation contribute to the work surface the most delr> to the plane passing through the centerlines of the shafts and heads, on the corner of limit 0-15aboutcounterclockwise when viewed from the outlet end edge of the baffle to the axis of rotation of the apparatus, and this is done by rotating sprinkler nozzles fixed on the baffle. Improving the quality of rain additionally achieved due to the fact that the final working parts of the deflectors are about at their intersection with the centerline of the nozzle orifice permanent bend, aimed in the direction of the water ejected under pressure from the cylindrical holes of the nozzles. And even as the rain improved due to the fact that the end edges of the deflectors, width approximately in the limit of 0 5 mm have the bend directed in the same direction, as mentioned, but with the depth and width of edges decreasing as the distance from the middle of the width struisbaai of each deflector in each direction, which is explained by the fact that the greatest force of the collision jet cylindrical baffle is required for the cross-section of the jet with the highest vertical chord diameter of the jet.

In Fig. 1 shows srednesrocnye sprinkler device in normal position; Fig. 2 then W is com rocker mechanism of rotation, on the long barrel of the apparatus of Fig. 4 General view of the deflector, mounted on the sprinkler nozzle is placed above the jet blade and bending the rocker arm mechanism for rotation on a short shaft of the apparatus; Fig. 5 diagram of the emission of jets of water out of the holes (nozzles) sprinkler nozzles without deflectors and baffles, when the normal position of the apparatus is installed, for example, on the delivery pipe sprinkler of Fig. 6 is the same, top view.

Srednesrocnye sprinkler apparatus includes a housing 1, a Central shaft 2, two diametrically spaced side trunk 3 (short and long) with sprinkler nozzles 4, with the angle between the axial lines of the nozzles ('olonne) and the horizon about 30aboutthe node of rotation of the rocker with the jet vane 5 at one end and a counterweight 6 on the other, two front 7 that restricts the rotation of the rocker arm, rigidly connected with trunks 3 and ground (P), and return spring 8. Directly with housing (nareshbhai part) sprinkler nozzles 4 a long side of the trunk, placed under the counterweight 6 of the rocker arm, rigidly connected strap 9, and also, but additionally by means of the l-shaped bracket 10 is fixed on the nozzle 4 to the a rule into two equal halves by a vertical plane, passing through the centerline of all trunks apparatus is rigidly attached to the narrow ends of the vane deflectors 11, diverging away from the center of rotation of the device sidewalls at an angle . Approximately 10 mm from the outer struisbaai edge of each baffle has a constant angle of bend1with limit 0-20aboutdirected away from crossing it, around the bend centerline'olonne to the horizontal position (G). The entire baffle 11, counting from the mounting plate 9, has a variable, adjustable, for example by a screw 12, the angle2equal to the limit 0-20aboutby means of which the angle 1reaches their sum angle puts bent end portion of the deflector is approximately horizontal position G, with a standard deviation 010about. Thus in the normal position of the apparatus when P mechanism of rotation of the top end, the working portion of the deflector has a horizon angle 0+10aboutand when the device is upside-down P down too 0+10aboutto the horizon. The quality of the rain it's better when the stream coming down under high speed the pressure of the atmosphere, slightly elevated. To further improve the quality of rain the best of the fragmentation of jets in small drops, the final RA is different and width edges, for example, decreasing as the distance from the middle of the width struisbaai of each baffle. The latter is explained by the fact that the greatest force of the collision jets cylindrical departing from the cylindrical nozzle orifice, deflector required for the maximum chord of the jet since the diameter.

In Fig. 5 and 6 shows the scheme of work unit without vent with rain D1with the jets emitted by the nozzles at angles of about 30aboutto the horizon, the height h1with a radius of R1in the form of narrow strips, falling on irrigated field, with a large instantaneous intensity1with a large windage in the vertical plane, and therefore with great loss of efficiency of the rain on the entrainment by wind and evaporation and greater environmental harm irrigated earth. Same, but with the best record shows the device with baffles giving rain D2with a smaller height h2the smaller the radius R2and constituting on the field a large area of precipitation less dynamic power, low intensity2and rain, with less loss of efficiency on the entrainment by wind and evaporation and less environmental harm irrigated soil erosion and salinization.

The estimated technical solution simplifies the design, reduces the consumption of materials and the complexity of manufacturing and significantly improves the quality of the rain. It can be used as in the manufacture of new sredneshirotnykh sprinkler apparatus on the basis of analogues, and the modernization of hundreds of thousands of machines in operation.
