Irrigation system tower support wheel

In combination,

• an irrigation system having at least one tower support, irrigation means and drive means;
• at least one irrigation system tower support wheel, each of said wheels comprising;
• a generally cylindrical wheel rim having outer and inner surfaces, first and second edges and a center longitudinal axis;
• said wheel rim having a generally flat cross-section;
• said wheel rim free of openings extending between said outer and inner surfaces whereby mud and dirt may be prevented from passing therethrough;
• said wheel rim further comprising first and second inwardly extending peripheral side flanges connected to said first and second edges respectively, such that additional rigidity may be imparted to said cylindrical wheel rim;
• support means extending inward towards said center longitudinal axis, said support means mounted on said inner surface of said wheel rim;
• support means extending inward towards said center longitudinal axis, said support means mounted on said inner surface of said wheel rim;
• said support means adapted to be rotatably mounted on one of said tower supports such that said tower support may roll thereon;
• a plurality of lugs mounted on said outer surface of said wheel rim;
• each of said lugs comprising a longitudinally extended channel having an upper edge comprising the base of the V-shaped channel and two lower edges comprising the open edges of the V-shaped channel;
• each of said lugs mounted on said outer surface of said wheel rim such that each of said lower edges is adjacent and connected to said outer surface;
• each of said lugs extending substantially across the entire width of said outer surface of said wheel rim;
• and
• each of said lugs extending substantially parallel with said center longitudinal axis of said wheel rim.

An irrigation system tower support wheel for use in combination with an irrigation system having at least one tower supports, irrigation means and drive means, said support wheel comprising;

• a generally cylindrical wheel rim having outer and inner surfaces, first and second edges and a center longitudinal axis;
• said wheel rim having a generally flat cross-section;
• said wheel rim further comprising first and second inwardly extending peripheral side flanges connected to said first and second edges respectively, such that additional rigidity may be imported to said cylindrical wheel rim;
• said cylindrical wheel rim having a rim width, as measured parallel to said center longitudinal axis along said outer surface of said wheel rim, greater than one-fifth (1/5) of a diameter of said cylindrical wheel rim;
• said cylindrical wheel rim further comprising two cylindrical sections connected to one another in concentric relation such that a cylindrical wheel rim is formed;
• support means extending inward towards said center longitudinal axis, said support means mounted on said inner surface of said wheel rim;
• a plurality of lugs mounted on said outer surface of said wheel rim;
• each of said lugs comprising a longitudinally extended channel having a V-shaped cross-section, said channel further having an upper edge comprising the base of the V-shaped channel and two lower edges comprising the open edges of the V-shaped channel;
• each of said lugs mounted on said outer surface of said wheel rim such that each of said lower edges is adjacent and connected to said outer surface;
• and
• each of said lugs having a length greater than said width of said wheel rim such that at least one end of each of said lugs may overhang at least one of said first and second edges of said wheel rim.

A wheel for use with agricultural and construction implements, said wheel comprising;

• a generally cylindrical wheel rim having outer and inner surfaces, first and second edges and a center longitudinal axis;
• said wheel rim having a generally flat cross-section;
• said wheel rim further comprising first and second inwardly extending peripheral side flanges connected to said first and second edges respectively, such that additional rigidity may be imparted to said cylindrical wheel rim;
• support means extending inward towards said center longitudinal axis, said support means mounted on said inner surface of said wheel rim;
• a plurality of lugs mounted on said outer surface of said wheel rim;
• each of said lugs comprising a longitudinally extended channel having a V-shaped cross-section, said channel further having an upper edge comprising the base of the V-shaped channel and two lower edges comprising the open edges of the V-shaped channel;
• each of said lugs mounted on said outer surface of said wheel rim such that each of said lower edges is adjacent and connected to said outer surface;
• each of said lugs extending substantially continuously across the entire width of said outer surface of said wheel rim;
• each of said lugs extending substantially parallel with said center longitudinal axis of said wheel rim;
• and
• said wheel rim, said support means and said lugs comprising a metal material.
