Guide system for breakaway cables of agricultural sprayer booms

A guide system for use with a breakaway cable of a sprayer boom of an agricultural sprayer, wherein the sprayer boom includes a first boom section and a second boom section defining a breakaway boom section of the sprayer boom with a breakaway joint having the breakaway cable extending between the first boom section and the breakaway boom section for controlling movement of the breakaway boom section with respect to the first boom section, the guide system comprising:

• a first guide supported relative to the first boom section and having an interior passage extending generally in alignment with first boom section;
• a second guide extending through the interior passage of the first guide with the second guide and having an interior passage, the second guide:
• being a guide tube with a circumferential sidewall extending about respective the interior passage of the second guide;
• and
• being configured to move with respect to the first guide and the first boom section during movement of the breakaway boom section with respect to the first boom section;
• a spring supported by the first boom section for biasing the breakaway boom section to a neutral position;
• and
• an anchor at an inner end of the guide tube, and wherein the ends of the pair of cables and the spring are attached to the anchor;
• wherein:
• the breakaway cable extends through the interior passage of the second guide;
• the cable is one of a pair of cables extending between the first boom section and the breakaway boom section and through the second guide;
• the first guide is a roller guide having a pair of spaced-apart rollers arranged on opposite sides of the second guide to limit transverse movement of the second guide;
• the guide tube is aligned with the spring, and the pair of cables connects to the spring at an outer end of the guide tube;
• the outer end of the guide tube faces toward the spring and is attached to the spring;
• and
• ends of the pair of cables and the outer end of the guide tube move contemporaneously with each other.
