(57) Abstract:Usage: in sprinkler technology. The inventive sprinkler apparatus consists of a cap nut 1, the jet vanes 3 and the housing 2 with streamresult channel 5 and emphasis with an oblique cut 8. Case 2 above streammessage channel 5 made in the form of a vertically arranged shaft 6, at the end of which is rigidly fixed cantilever shoulder 7 with the stop 8. The rod 6 is pivotally planted reactive blade 3, which is the bottom of the blade 11, and the top stop with an oblique cut 10. When hitting the stop 10 stop 8 case 2 rotates and the blade 3 will be released and the coverage of rain. 1 C.p. f-crystals, 5 Il. The invention relates to the field of mechanization, irrigation of agricultural crops and can be used in sprinkler technology. In particular, when you want to use low-flow sprinkler apparatus, forming a low-intensity artificial rain in small drops.Known srednesrocnye sprinkler apparatus, including the cap nut, the case with sprinkler trunks and spring-loaded arm with a movable wedge deflector  the Disadvantage of this sprinkler system is the complexity of the design due to applied the second apparatus, selected as a prototype containing the cap nut, the case with sprinkler trunks and stop arm on my shoulder which has hydraulic valve with the rod interacting with a focus on the body 
The disadvantage of this sprinkler system is lack of reliability and the design complexity, obuslavlivaya using membrane or other hydraulic actuator to move the rod. In addition, the principle of operation is caused by the necessity of dividing the input flow of water at least two components, which reduces the reliability of operation of the rotation mechanism at low costs.The aim of the present invention is to simplify the design and improve reliability.This objective is achieved in that in the sprinkler apparatus containing installed on the inlet line of the rotary body with streamresult channel and stop having a slanting cut to interact with the same emphasis jet drive housing above streammessage channel is made in the form of a vertical rod and provided with a rigidly fixed on his console cone together, and jet drive made in the form of blades, hinged with two degrees of freedom fitted orsolina shoulder, the focus of the jet drive on the opposite side of the blade relative to streammessage channel. In addition, the mounting of the cantilever shoulder on the rod is arranged to change its position relative to streammessage channel.In Fig. 1 shows a sprinkler apparatus (General view), Fig. 2 - jet vane (bottom view) with blades of Fig. 3 is a view along arrow a of Fig. 4 and 5 are working on a sprinkler system.Sprinkler apparatus consists of a cap nut 1, the rotary body 2 and the jet vane 3. In the pivot housing 2 has power 4 and Streamray 5 channels. Above streammessage channel 5 case is made in the form of a rod 6, on the end of which is rigidly fixed cantilever shoulder 7 with the stop 8. Union nut 1 hinged planted on the housing 2, against axial movement she held the top ledge on the housing 2 and the lower sleeve 9, is rigidly connected with the rotary body 2.On the rod 6 with the possibility of rotational movement and axial movement planted jet vane 3, from above it has the focus 10 with an oblique cut, and the bottom of the blade 11.The mutual position of the cantilever shoulder 7 about the axis streammessage channel 5 (see Fig. 3) characterizes the melt as follows.Water under pressure from supply line enters the channel 4 and then through streamresult channel 5 is emitted in the form of rain on the irrigated area. When this sprinkler jet, impinging jet blade 3 and the blade 11, cranks and moves it along the rod 6 up (see oripa. 4). Emphasis 10 with an oblique cut of the blade strikes the stop 8, also with an oblique cut on the cantilever arm 7. Due to this, the body 6 rotates through some angle. While jet vane 3 will be in position outside the coverage area of the sprinkler jet (see Fig. 5).Then the blade under the action of its gravity, will move again down, and the jet will again turn to her and pick up the case again rotated relative to the nut 1. Thereby automatically rotating body, i.e., running irrigation sprinkler apparatus in a circle. The change of angle a is regulated by the speed of rotation of the housing. With a smaller angle speed increases, with larger decreases.Thus, thanks to the distinctive features of the proposed technical solutions sprinkling apparatus has received the possibility to exclude hydraulic valve hydraulic rod and thereby have the config on the inlet line of the rotary body with streamresult channel and focus, having a slanting cut to interact with the same emphasis jet actuator, characterized in that the housing above streammessage channel is made in the form of a vertical rod and is provided with rigidly attached to the end of the cantilever arm, and a jet drive is made in the form of blades, hinged with two degrees freely mounted on the shaft and provided with side streammessage channel blades, while the rest of the body is placed on the cantilever arm, the emphasis jet actuator on the back of relatively streammessage channel side of the scapula.2. The apparatus according to p. 1, characterized in that the attachment of the cantilever shoulder on the rod is arranged to change its position in the plan with respect to an axis streammessage channel.
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.
