The invention relates to agriculture, in particular to sprinkler devices, and can be used in irrigated agriculture for irrigation of agricultural lands.

Known sprinkler apparatus DD-30 with turbine drive and worm gear mechanism, which can operate both on the sector and on a circle [1]

The disadvantage of this device to assuredremote;

when irrigation sector the device is slowly coming back, pouring freshly watered area, which creates at the endpoints sector adverse watering.

Closest to the invention is a sprinkler apparatus Dew-3", including housing, which is fixed to the main rotary shaft with nozzle and two auxiliary trunk with nozzles that are hydraulically communicated with the main and fixed it. The drive unit is made in the form of a complex impact plate which is positioned on the vertical axis and provided with a return spring [2]

The disadvantages of this apparatus are the design complexity, low reliability; lack of irrigation sector.

The purpose of the invention to simplify the design, improving reliability and enabling irrigation sector.

This is achieved by the sprinkling apparatus comprising a fixed housing, which is rotatably installed is equipped with a nozzle main shaft, which is fixed to an extra barrel, the latter is fixed on the main nozzle can be rotated between the limits fixed at last, and communicated with the cavity of the main nozzle through PR is key opposite its open end and which is fixed to an extra barrel, at last opposite the fixed nozzle arm with a hook, and the body is equipped with adjustable stops between which is placed the toe of the lever, and the additional shaft connected to the vertical part of the main shaft through the medium of a return spring.

In addition, one limiter is set so that provided additional fixation of the stem at an acute angle to the main nozzle, and the other opposite to the first stopper attached so that provided the location of the optional shaft at right angles to the main trunk, and in the first position of the additional barrel through the valve is in communication with the longitudinal tube, and at the second position directly with the cavity of the main trunk.

In addition, the stoppers fitted with shock absorbers shock.

Distinctive features of the proposed technical solutions in conjunction with the known achieve a positive effect, which consists in simplifying the design, increasing reliability and providing irrigation sector, because there is no need for complex percussion shoulder, one upper secondary barrel with a nozzle, provided with the intermittent rotation of the apparatus due to the presence of the tube and from one end position to the starting point i.e. no double irrigate the same area.

In Fig.1 shows a sprinkler apparatus, General view (a partial longitudinal section); Fig.2 a fragment of the sprinkler system, the interaction of the main nodes at the time of rotation of the additional shaft, when it is located along the core; Fig.3 hydraulic and kinematic diagram of the sprinkler system with irrigation from the original point of the sector, a partial cross-section, plan, and Fig. 4 is the same, when returning the rotary shaft from the end point of the sector in the initial.

Sprinkler apparatus consists of a fixed housing 1, which is rotatably mounted a rotary shaft 2 with the nozzle 3, which is fixed to the additional shaft 4 with the nozzle 5.

To provide intermittent rotation of the additional shaft 4 in the working position, i.e. when watering, communicated with the cavity of the main shaft 2 with a longitudinally located in the last tube 6, the end of which is directed to the main nozzle.

To ensure the irrigation sector additional barrel 4 is fixed with the possibility of rotation between the limiters 7 and 8, fixed on the main shaft 2 and provided with a lever 9 with hooks 10. The lever 9 is placed on the opposite SS="ptx2">

To ensure the rapid return of the rotary shaft 2 in the starting point of the sector with the aim of preventing re-irrigation freshly watered soil, additional barrel 4 is in communication with the cavity of the main shaft 2 and the tube 6 through the valve 13, which is placed at the end of the latter opposite its end face that is directed toward the nozzle 3. In the valve body 14 made two holes 15 and 16, the first of which communicates with the cavity of the main nozzle 2, and the second with the cavity of the tube 6.

On the rod 17 of the valve 13 additional fixed barrel 4, with the rod 17 made the hole 18.

For quick changes direction additional shaft 4 and to avoid stopping the device first connected to the vertical part of the main shaft 2 of the return spring 19, which is fixed an eccentric shaft 17, i.e., the eccentric rotary axis of the additional shaft 4 (Fig.1 and 2).

To achieve the goal of one limiter 7 is installed so that provided additional fixation of the stem 4 at an acute angle to the main trunk, and the other opposite the limiter 8 is fixed so that provided the location of the optional shaft at right angles to the main (Fig.3 and 4). In the first position is as 2, i.e. in the first position, the opening 18 of the stem 17 of the valve 13 coincides with the hole 16 of the housing 14 of the crane, and in the second position with the hole 15.

For damping shock limiters 7 and 8 fitted with shock absorbers 20 and 21 hits in the form of the damping elements.

Sprinkler apparatus operates as follows. In the working position when making irrigation more barrel 4, when viewed from above, is located at an acute angle to the primary and is pressed by a spring 19 to the limiter 7. Water from riser irrigation network is fed into the housing 1, and then in the fixed barrel 2, and from there through the tube 6 and the holes 16 and 18 of the housing 14 and the stem 17 of the valve 13 in additional barrel 4. Departing from it at an angle to the main shaft 2 jet creates a reactive force, due to the recent along with it is located the tube 6 starts to rotate, which causes the formation of centrifugal force, under the action of which water tends not into the tube 6, and Vice versa, and that leads to the cessation of water flow in the secondary shaft 4 and therefore to the destruction of reactive power, which leads to the stopping of the main shaft. At this point, the maximum range of the jet, i.e., poured a large circle. During the rotation of the APC is tx2">

After the machine stops, the centrifugal force disappears, and the water again enters the tube 6 and the additional shaft 4, i.e., the cycle repeats. Thus, it provides a discrete rotation of the apparatus (Fig.1, 2, 3). This movement continues until the hook end 10 of the lever 9 will not come into contact with the stop 12, in which the lever 9 will turn the extra barrel 4, and the spring 19 provides a sharp turn last. Additional barrel 4 will be installed at right angles to the main shaft 2. Thus overlaps the hole 16 and the hole 18 of the stem of the valve 13 coincides with the opening 15 in the body, resulting in water directly, bypassing the tube 6 enters additional barrel 4. Since the latter is set at a right angle to the main shaft 2 provides the fastest turn to its original position, i.e., each time the motion of the vehicle and begin watering from the source point, preventing the loss of artificial rain on freshly watered area (Fig.4).

When you return the main shaft 2 to the starting point hook 10 of the lever 9 strikes the stop 11, resulting in additional shaft 4 turns sharply and is set at an acute angle to the main shaft 2 (Fig.3 position "dead spots". Starts again described cycle of irrigation.

For a circular watering stops 11 and 12 are removed.

When irrigation sector additional trunk every time strikes the stops 7 and 9, while the force of the blow extinguished the shock absorbers 20 and 21, which eliminates breakage.

The proposed apparatus is simpler in construction, more reliable and provides both circular and irrigation sector.
