(54) WHEELED RAIN PIPELINE

(57) The invention relates to agriculture. The purpose of the invention is to reduce the loss of time and simplify the process of leveling the pipeline, improving reliability. Wheeled

The sprinkler pipeline includes a connection unit 1 to the hydrant, running wheels 2, drive 3, sectional conduit 4, on which sprinkling nozzles 5 and drain valves 6 are mounted. Between the sections of the conduit 4 there are installed clutches (MO) 7, which allow transit flow of water. Moving to a new position is carried out with MS 7 turned on. In case of violation of the pipeline straightness, MS 7, located at the boundaries of the curved sections of conduit 4, is turned off by pulling the spring-loaded finger out of the hole. Then, using the drive 3, to remove the pipeline until the linearity of the entire conduit 4 is restored. After the alignment of the conduit 4, MS 7 is switched off again. 1 hp f-ly, 2 ill.

FiV.1

The invention relates to agriculture and can be used in irrigation of crops with multi-support sprinkler machines.

i The aim of the invention is to reduce time loss and simplify the process of aligning the pipeline, improving reliability.

I FIG. schematically shows the I-wheel sprinkler pipe, jvid in plan; figure 2 - coupling coupling, General view.

The wheel sprinkler pipeline includes a node I connected to a hydrant, running wheels 2, a drive 3, a sectional conduit 4 on which the sprinkler nozzles 5 and drain valves 6 are mounted, and between the sections of the conduit there are clutches 7 that allow transit flow.

The clutch 7 consists of internal 8 and external 9 nozzles, I, the internal diameter of the nozzle 8 being equal to the internal diameter of the conduit i the nozzles 8 with the housing 10 attached to | the flange of the segmented conduit 4. The connecting nozzle 9 of the flange 12 is attached to the flange | The conduit section 4, and flange 14 is installed in the housing 10 of the internal nozzle 8 with the help of the locking ring 15. This allows rotation of the nozzle 9 relative to the nozzle 8 and limiting their mutual axial movement. To prevent water from leaking in the gaps between nozzles 8 and 9, a lip seal 16 is installed. In the end surface of the flange 14 and the stop ring 15, open holes 17 to enter the spring-loaded pin 18 mounted on the flange AND controlled either manually or with by means of a hydraulic or electric drive 19. Moreover, in the flange 14, the holes 17 are placed along the diameter of a circle of radius with a pitch that makes it possible to easily adjust the necessary mutual arrangement of the adjacent sections of the conduit 4.

The pipeline works as follows.

A wheeled sprinkler pipe installed on the leveled off position is connected to a closed irrigation network using the connection unit 1 of the hydraulic unit and, opening a hydrant, it releases water. After the irrigation rate is over, the hydrant is closed, disconnected

the pipeline from the closed irrigation network, drain water from it and with the help of drive 3 rolls onto the position.

In this case, all clutches 7 of the clutch should be included, i.e. their spring-loaded fingers 18 are inserted into the holes 17. As a result, the free rotation of the external pipe 9 relative to the internal pipe 8 is prevented and the torque from the drive 3 is transmitted between all sections of the conduit 4. Thus, when the clutch couplings 7 are turned on, similar to the sprinkler wheeled pipe DKSCH-64 Volzhanka.

If a new pipeline is found to be at a new position, the pipeline will proceed as follows.

Specify the location and magnitude of the curvature of the conduit, disconnect the clutch 7 clutch, located on one or both sides of the drive 3, at the boundaries of the curved sections of the conduit 4

For this, either by

I.

hydro or electric drive, output

the spring-loaded pin 18 from the hole 17. As a result, the external nozzle 9 is able to rotate relative to the internal nozzle 8. Then turning on the drive 3, roll back. the pipeline is moved forward or backward until the straightness of the entire conduit 4 is restored. In this case, only the pipeline section which includes the driving carriage 3 and sections of the conduit 4 rigidly interconnected by the clutch couplings 7 is rolled, and the other three are only unfolded.

If conduit 4 is not evened out at one time, it is necessary to repeat all the operations outlined above, turning on and off the corresponding clutch 7.

After aligning the conduit 4, all of the disengaged clutches 7 are turned on again and the actuator 3 is finally used to install the pipeline in a new position, then it is connected to the irrigation network and the irrigation process is repeated.
