Abstract
The present invention provides a tire assembly for irrigation systems that prevents the formation of ruts caused by repeated travel along a path by tires of a mobile vehicle or structure. The tire assembly includes dual tires with a flexible belt member wrapped around the outer periphery of the two tires having a plurality of cleat members located on the outer surface of the flexible belt member. The cleat members direct water away from the center of the travel path. The flexible belt member further includes plural center guides to keep the belt in place. The tire assembly reduces soil compaction by providing a greater ground engaging surface area to more evenly distribute the weight of the equipment and by directing water away from the center of the travel path.
Claims12
An irrigation system having an elongate boom having a plurality of sprinklers connected to a water supply and supported above the ground to supply water to a selected ground area;
- comprising:
- plural tower structures that support the boom, each tower structure having a tire assembly for moving the tower structures repeatedly along a travel path having outer sides, the tire assembly having a width and including two tires mounted side-by-side on an axle with a flexible member mounted on the two tires about their outer periphery so that the flexible member engages the ground as the tires rotate to move the towers across the ground, the flexible member including plural around engaging elements, wherein one of the two tires has an inflation pressure less than the other of the two tires.
A tire assembly for moving a mobile irrigation system along a travel path;
- comprising:
- first and second tires each having an outer periphery and mounted side-by-side on an axle, wherein one of the first and second tires has an inflation pressure less than the other of the first and second tires, and
- a flexible member mounted about the outer periphery of the first and second tires, the flexible member having an outer ground engaging surface that engages the ground as the tires rotate to provide a surface area over which weight of the irrigation system is distributed to prevent formation of ruts.
A device for mounting onto a tire assembly for moving a mobile irrigation system along a travel path, the tire assembly including first and second tires each having an outer periphery and mounted on an axle, wherein one of the first and second tires has an inflation pressure less than the other of the first and second tires, the device comprising:
- a flexible belt member having an inner surface that engages the outer periphery of the first and second tires and an outer surface that engages the travel path to provide a surface area over which weight of the irrigation system is distributed to prevent formation of ruts.
