The present invention relates generally to crop irrigation/planting. More specifically, the present invention relates to systems and method of crop irrigation, chemigation, fertigation and/or planting, and components of irrigation/chemigation/fertigation/planting systems. Even more specifically, the present invention relates to moving irrigation (such as pivot-style or linear/lateral move style) systems and method of crop irrigation, chemigation, fertigation and/or planting, and components of moving irrigation/chemigation/fertigation/planting systems.
Moving irrigation systems, such as center pivots (or linear/lateral move style irrigation systems) are complex machines that are commonly used for crop irrigation. A center pivot generally comprises one or more span pipes (spans) supported on wheeled towards above the crops, and connected to a central pivot point to deliver water to the field surrounding the central pivot point via spraying heads connected to goosenecks positioned along the spans. While center pivot (and linear/lateral move) technology provides many benefits over other types of surface irrigation, the elevated location of the sprayer heads, and the non-laminar flow of water can result in significant evaporation. In addition, such systems typically are not capable of use for chemigation, fertigation and/or planting. Furthermore, moving irrigation systems are not as effective and even subject to damage in high winds.
Therefore, it is desirable to provide moving irrigation (such as pivot-style or linear/lateral move style) systems and method of crop irrigation, chemigation, fertigation and/or planting, and components of moving irrigation/chemigation/fertigation/planting systems that overcome the deficiencies and/or provide additional benefits to conventional technology.
The instant invention provides moving irrigation (such as pivot-style or linear/lateral move style) systems and method of crop irrigation, chemigation, fertigation and/or planting, and components of moving irrigation/chemigation/fertigation/planting systems. Some embodiments of the invention include unique spraying heads that attach to the end of a gooseneck attached to a span. The spraying head of the present invention is generally ball-shaped with a hollow center that fills up with water during irrigation to add weight to the spraying head. The added weight allows the spraying head to be pulled through the crop canopy by the irrigation system and reduces deflection of the spraying head due to gusts of wind. In some embodiments the spraying head is an omni-directional spraying head. In some embodiments the spraying head is pre-drilled (or otherwise manufactured with orifices) to result in predetermined discharge parameters. In other embodiments, the spraying head is capable of being drilled by the end user to the specific discharge parameters desired by that end user.
In some embodiments of the present invention, the spraying head is used in combination with a unique gooseneck of the present invention. In other embodiments, the spraying head is used in combination with conventional goosenecks. In still other embodiments, the gooseneck of the present invention is used in combination with conventional spraying heads.
In some embodiments of the present invention, the gooseneck is structured to position a spraying head below the crop canopy. In some embodiments, the gooseneck of the present invention includes a connecting system to reduce stress on the threads going into the main pipe of the span. In some such embodiments the connecting system provides additional support of the gooseneck to the main pipe. In some such embodiments, the connecting system supports the drop and, in some embodiments, also allows the end user to move the drop to hit a specific row desired in the crops. In some embodiments, the gooseneck includes a coupling for tethering multiple goosenecks together along a span to create a stabilizing force along the span.
Some embodiments of the present invention include a roller pipe. The roller pipe allows the end user to place sprayer heads a desired heights within the field. In some embodiments the pipe is made of HDPE plastic to minimize weight and allow for on-sight repairs. In some embodiments, the roller pipe is supported by an inventive cradle-roller assembly.
Some embodiments of the present invention include a unique span main pipe that allows for irrigation, chemigation, fertigation, hydraulics and electrical through a single span. Some embodiments of the present invention include a shield attachment to help prevent deep rutting from ground saturation and the weight of the span wheels.
Some embodiments of the present invention include a bladder system that is fillable with water and connected to wheelbase of the span to help anchor the span during high winds or other similar events.
Some embodiments of the present invention include a counterweight device use to help prevent rollover of a moving irrigation system.
Some embodiments of present invention include a system to plant cover crops.

In some embodiments of the present invention, the roller pipe 110 is portioned to have a plurality of internal sections. One embodiment of the present invention includes four internal circular cross-sections adjacent to each other. This creates nine total separate internal lines of the roller pipe 110—the four circular cross-sections themselves, a central curved-diamond-shaped space in-between all four of the circular cross-sections, and four curved-triangle-shaped spaces between the adjacent circular cross-sections. Some embodiments of the present invention include a differing number of internal circular cross-sections. In some embodiments, the internal cross-sections may be other shapes. In some embodiments, the internal circular cross-sections are HDPE lines. In some embodiments, these are 1¼′ HDPE lines.
In some embodiments the roller pipe 110 is linear. In some embodiments, the roller pipe 110 is curved. In some embodiments of the present invention the roller pipe 110 has a substantially circular cross-section. It will be appreciated that other cross-sections may be used for the roller pipe 110. In some embodiments, the roller pipe 110 is reinforced with various support structures. In some embodiments this includes, various frames, braces, struts, support rods, and other commonly known support structures.
In some embodiments, the cradle-roller assembly 120 is used to attach the roller pipe 110 to the main pipe 100. The cradle-roller assembly 120 includes a plurality of cradles 122. Each cradle 122 is attached to the main pipe 100. In some embodiments, the cradles 122 are hung from the main pipe 100 via rope, chains, string, or by similar means. Each cradle 122 is capable of holding the roller pipe 110 inside the hollow center. In some embodiments, each cradle 122 includes three pairs of rollers 124 spaced out from each other. The rollers 124 engage the roller pipe 110 held inside the cradle 122 so that there are three separate points of contacts between each cradle and the roller pipe. In some embodiments, additional rollers are used. In some other embodiments, no rollers are used and the roller pipe 110 is contained within the walls of the cradle 122 only.
The roller pipe 110 allows the end user to place sprayer heads a desired heights within the field because the cradles 122 of the cradle-roller assembly 120 may be easily adjusted in reference to the main pipe 100. This is done by adjusting the length of the rope, chain, string, or other device used to attach the cradles 122 to the main pipe 100 thereby lowering or raising the height of the roller pipe 110.
In some embodiments, the roller pipe 110 has a plurality of nozzles 210 spaced on top and along the span of the pipe. Each nozzle 210 on the roller pipe 110 functions similar to those on the main pipe 100. In some embodiments, the nozzles 210 may be on the bottom or side of the roller pipe 110. In other embodiments, they may be placed in any combination thereof. In some embodiments, the gooseneck 200 attachments may be welded to the roller pipe 110.
The main pipe 100 is attached to one or more wheel assemblies 130. In some pivot-style embodiments, one end of the main pipe 100 is attached to a central pivot. In those embodiments, the other end of the main pipe 100 is attached to a wheel assembly. Depending on the length of the main pipe 100, additional wheel assemblies 130 may be attached to the main pipe 100 along its span. In some lateral movement style embodiments, wheel assemblies 130 may be attached to both ends of the main pipe 100.

In some embodiments, the wheel assembly 130 comprises a triangular shaped structure attached to the main pipe 100 on one point and wheels on the other two points. Therefore, the two points attached to the wheels are coplanar and closer to the ground while the third point is elevated above approximately in between the two points attached to wheels. In some embodiments, this triangular shape is created by attaching three linear rods into a triangle. Therefore, the bottom rod is approximately parallel to the ground.
In some embodiments, the wheel assembly 130 includes an anchor 140 designed to negate irrigation drop during storms. In some embodiments, the anchor 140 is attached to the bottom rod, or the bottom portion, of the wheel assembly 130. In some embodiments, this anchor 140 is a bladder adapted to be filled with water delivered by the main pipe 100. The bladders may be filled when needed and then released and emptied by the operator. The weight of the bladder provides a breaking effect on the wheels and weighs down the assembly. Some embodiments of the present invention include a counterweight device use to help prevent rollover of a moving irrigation system.
In some embodiments a motor is attached to one or more of the wheel assemblies 130 in order to power the wheels and move the main pipe 100 across the field.
