Sprinkling apparatus

 

(57) Abstract:

Usage: in the mechanization of agricultural production, namely, in the technique for irrigation of agricultural crops by irrigation. The inventive sprinkler apparatus consists of a fixed housing 1, tribes 2, barrel 3 and the nozzle 4. On the shaft 3 are the outlets 5 and 6, the axis of which is perpendicular to the axis of the barrel. The outlets are directed in opposite directions. 2 Il.

The invention relates to the mechanization of agricultural production, and in particular to techniques for irrigation of agricultural crops by irrigation.

Known ink-jet sprinkler system watering in a circle or sector that contains one main trunk or provided with an additional bore and having a mechanism of rotation of the trunk (Lebedev, B. M. Sprinkler, M., "engineering", 19770 C. 30-59).

Lack of data sprinkler devices is the design complexity of the mechanism of rotation of the barrel sprinkler system.

Known sprinkling apparatus, which is the closest to the proposed, comprising a fixed housing, a barrel with a nozzle, rotating under the action of the reaction stream, and add what are uneven rotation, the complexity of the design of the braking mechanism of the barrel, reducing the flight distance of the jet due to bending of the trunk (rotating flow).

To resolve these shortcomings allows the proposed sprinkler apparatus, comprising a fixed housing, a knee with a fixed barrel and a nozzle, which is characterized by the fact that the barrel is provided with an additional trueorigin outlets located perpendicular to the axis of the barrel and pointing in opposite directions.

The essence of the proposed technical solution is that additional truepromise the floodgates create a torque directed in opposite directions, one of which provides the rotation shaft, and the other, smaller in absolute value, is inhibitory.

In Fig. 1 shows a sprinkler apparatus, side view; Fig. 2 is a top view along arrow A.

Sprinkler apparatus consists of a fixed housing 1, tribes 2, barrel 3 and the nozzle 4. On the shaft 3 are the outlets 5 and 6, the axis of which is perpendicular to the axis of the barrel. The outlets are directed in opposite directions.

Sprinkler apparatus operates as follows.

The jet of water exiting the m streams. The reactive force R' does not create a torque about the axis of rotation 7 of the apparatus. Reactive forces R and r generate torques Min=RL and MB1=rl acting in opposite directions. L and l respectively, the shoulders of the application of reactive forces. By varying the diameters of the outlets D and D, as well as the shoulders L and l, reaches a constant speed of rotation of the shaft 3 about the axis 7 of the apparatus. When L= l braking force creates a stream flowing from the outlet of smaller diameter.

Thus, the proposed technical solution, being structurally simpler ensures smooth rotation of the shaft of the sprinkler system and thereby the uniformity of irrigation.

Sprinkling apparatus comprising a fixed housing, knee and turning the barrel with a nozzle, characterized in that the shaft is arranged perpendicularly to its axis truepromise the outlets directed in opposite directions, are made of different diameters and spaced from the axis of rotation of the shaft at different distances.

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.
