(57) Abstract:Usage: in the agricultural industry, in particular in devices for irrigation. The inventive sprinkler apparatus has a rotary shaft 1, which rotates under the action of the reactive force of the water jet emitted from the nozzle 3, the axis of which does not intersect with the axis of rotation of the barrel 1 and is stabilized by the lever 4. The end of the last made in the form of curved vanes 5, located at a distance from the shaft 1 on the side which is opposite to the direction of rotation. 1 C.p. f-crystals, 2 Il. The invention relates to agricultural machinery, mainly to the design of the sprinkler apparatus with a rotating barrel, designed for uniform distribution of water in the form of artificial rain over the irrigated area.Known sprinkling apparatus, the construction of which is used to bend the axis of the primary or secondary shaft, through which the axle is connected to a nozzle does not intersect with the axis of rotation of the barrel and creates a torque from the reactive force of the jet. As an example of this design can serve as a vehicle (SV, author's certificate N 1047442, class A 01 G 25/02, 1983, and also 
On the tx2">The disadvantages of devices of this type include high structural and technological complexity of braking devices that provide the desired rotational speed of the shaft.As a prototype of the invention mentioned selected sprinkler apparatus R-33. For braking the shaft in the apparatus used gear pump, Sipper special fluid through an adjustable choke.The disadvantages of this design are the following: structural and technological complexity and, as a consequence, the high cost, the dependence of the frequency of rotation of the barrel temperature uses a special fluid, which, in turn, due to the throttling undergoes a change in its temperature.The aim of the invention is to improve the reliability and durability by simplifying the structure.The objective is achieved by the fact that in the sprinkler apparatus containing the rotary barrel with a nozzle that is mounted at an angle to the axis of the rotary shaft, in place of their connection formed by the knee, on the rotary shaft fixedly mounted lever, the free end of which is made in the form of a curved blade, and which is mounted on the inner side of the knee.the USA of the nozzle on the value and.Distinctive features of the proposed technical solutions in conjunction with the known achieve a positive effect, namely, that significantly simplifies the design and manufacturing technology, enhanced reliability and durability, as it completely eliminates the rotation mechanism and inhibition of the trunk, including the moving parts and bearings, essentially, the design of the device remains the only one bearing, namely the bearing shaft;
significantly reduced the cost of the sprinkler system, and operational costs, since it eliminates the need for annual Assembly and disassembly for maintenance and winter storage devices lifetime can be parked;
for these same reasons, requirements decrease the weight parameters of the apparatus, eliminating the need for the annual build-up / dismantling, and therefore the apparatus can be made cheaper in comparison with aluminum alloy material, for example, of steel tubes for the manufacture of shafts, of cast iron for body parts.In Fig. 1 shows the relative positions of the parts, side view; Fig. 2 is a top view.The device works as follows.Jet emitted from the nozzle 3, creates a reactive force R, this creates a torque of Mkr=Rib. Under the action of this moment, the rotary shaft 1 starts to rotate. When this stream, if you look at it from above, curves (dotted line) and gets on the blade, the result is protivotumanki hindering the barrel 1. After inhibition of the barrel 1, the bending of the jet disappears, and she passes by the blades 5 at the maximum possible for their source data (pressure, nozzle diameter, the angle of the jet) distance. Protivotumanki disappears and the rotary shaft 1 under the action of the rotating moment again begins to rotate. The process is repeated. When the contact blade 5 jet flying at a closer distance, resulting in uniform coating of artificial rain all Rosemont jet flight, the decrease in intensity and increase the uniformity of distribution of rain. Moreover, all of the above is achieved while increasing reliability and simplifying its construction.Thus, compared with the prototype of the proposed device is more reliable, more durable, easier to manufacture. 1. Sprinkling apparatus comprising a fixed housing, which is rotatably mounted a curved barrel with a nozzle and a fixed arm having at the free end of the brake blade located at a distance from the axis of the nozzle is smaller than half the diameter of the nozzle, characterized in that, with the aim of improving the quality of rain, the barrel is curved in the horizontal plane in the form of a knee, and a nozzle mounted coaxially end portion of the barrel, the lever with the blade located on the inner side of the knee of the trunk.2. The apparatus according to p. 1, characterized in that the blade is made in the form of a flat plate, the end of which plane is curved away from the nozzle and width than the diameter of the nozzle.
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.
