    1506204 Irregation system VALMONT INDUSTRIES INC 27 March 1975 [29 March 1974] 13116/75 Heading AID Irrigation of a non-circular area using a centrally pivoted irrigation system is achieved by using a rotatable overhead main conduit 20 supplied at a central point 12, and provided with sprinklers 34, to which conduit is pivoted a boom 30 which includes a terminal auxiliary conduit 32 mounted on a steerable support tower 31. The tower 31 is steerable along a path defined by an electrical conductor 13, which may be buried or comprise a fence surrounding the area to be irrigated. The steering mechanism (not shown) of the tower 31 is coupled to a motor (not shown) controlled by a sensing device (not shown) mounted on the tower 31 and electromagnetically coupled to the energised conductor 13. Motor-driven towers 21 support the conduit 20, which comprises rigid sections flexibly connected at the towers 21. An end gun 33 provides for watering beyond the end of conduit 32.

    During the operation of the system, the main pipeline 3 makes a rotational movement with the help of self-moving supports 4. The position of the additional pipeline 7 relative to the main one is controlled by turning the wheels 9, caused by a signal from the sensing element when it deviates from the conductor 13, which ensures
    This invention relates to rural
    can be used in irrigation systems with a central swivel hub.
    The aim of the invention is to reduce crop damage.
    FIG. 1 shows a diagram of an irrigation system with a central swivel unit; in fig. 2 is a floor plan with an irrigation system, top view; in fig. 3 - additional piping with a beam, carrying wheel, top view; in fig. 4 - the same, front view; in fig. 5 is a diagram of the movement of the irrigation system when irrigating a square plot; in fig. 6 - the same, with irrigation of the area with an obstacle.
    The irrigation system contains a central swivel unit, combined with a water supply point connected to the water source 2. The main piping 3 mounted on self-moving supports 4 is rotatably fixed to the central pivot assembly 1. The main piping 3 consists of 4 rigid segments 5 arranged between the supports, interconnected with the possibility of rotation in a vertical plane to ensure follow-up on uneven terrain. Segments 5 of the main conduit 3 are reinforced with frame 6 to give them greater rigidity. To the last segment of the main pipeline 3 is pivotally attached additional pipeline 7, having one or. several supports 8. The length of the additional pipeline 7 connects 1/5 of the length of the main pipeline 3. Supports 4 and 8 contain wheels 9 driven by engines 10.

    9 wheels of an additional pipeline along a single trajectory. At the same time, the holding of additional and main piping equal to 1/5, as well as the location of the beam, carrier wheel 9, at an angle of 70 to the axis of the additional pipeline contribute to obtaining the minimum track width of the wheels 9. 6 Il.
    The main 3 and additional 7 pipelines contain a plurality of sprinkler nozzles 11 for spraying water. An additional nozzle 12 is also installed on the additional pipeline 7 for spraying water outside the area washed by the main 3 and additional 7 pipelines.
    To control the position of the additional pipeline 7 relative to the main pipeline 3, the system comprises an electrical conductor 13 buried in the ground, located along the perimeter of the irrigated field and connected to the current source 14 4 and a sensing element 15 responsive to the field produced by the conductor 13.
    Wheels 9 with engines 10, mounted on beam 16, supports 8 of additional pipeline 7 are installed by means of axles 17 on vertical supports 18. Racks 18 have the possibility of axial rotation and are interconnected by means of hinged rod 19. Sensitive element 15 is fixed on stand 18 . T ha 19 pivotally connected with the lever
    20 mounted on the sprocket 21 controls. The control sprocket 21 is associated with the driving sprocket 22 of the chain 23. The asterisk 22 is driven by the engine 24, which is controlled
    a relay 25 connected to the sensing element 15. The beam 16 carrying the wheels 9 is mounted to the axis of the additional pipeline at an angle of 70 °. In the irrigated area 26 there are obstacles 27.
    Irrigation system works as follows.
    The main pipeline 3 with the help of the driving wheels 9 installed on the supports 4, makes a rotational movement relative to the central rotary unit 1. The end of the main pipeline 3 describes the trajectory 28 on the irrigated section 26, which represents the circumference of the additional pipeline 7 relative to the main pipeline in process the movement is controlled by turning the wheels 9 on the support 8. The wheels 9 on the support 8 are turning due to the action of the engine 24 through the sprocket 22, the chain 23, the sprocket 21 and the lever 20 on a tug 19, if there is a control signal from a relay 25 switched on from a signal coming from the sensing element 15, when it is deviated away from the conductor 13. The end of the additional pipeline 7 describes the trajectory 29 on the irrigated section 26. 26 under the action of the end sprayer 12 is limited by the trajectory 30, which is close in shape to the shape of the section 26, taking into account the names of cis obstacles 27.
    The maximum irrigation radius required when the system passes corners of the square section 26 corresponds to the position of the additional pipeline 7 relative to the main 3 at an angle close to 180.
    However, when using an angle of less than 180, the irrigation area is reduced slightly, and managing the position of the additional pipeline 7 simplifies and reduces the required energy consumption. In addition, following the additional pipeline 7 in the corner zones of section 26 with a constant angle relative to the main pipeline 3 minimal crop damage from exposure
    O wheels 9 supports 8 corresponds to the orientation of the wheels 9 along a single trajectory. The location of the beam 16 at an angle of 70 to the axis of the additional pipeline 7 with the ratio of the lengths of the additional 7
    5 and the main 3 pipelines, equal to 1/5, provides minimal damage with almost maximum irrigation area.
