Abstract
A drive system for a net cleaner to produce efficient propulsion without damage to the cage net. The drive system includes flexible engagement stumps protruding from a base of a driving belt with tips or studs mounted on an end of the stumps. The tips or studs engage the net and propel the net cleaner. The stumps flex to insure that. if excessive pressure is applied to a stud, the stump will bend and the net will release without damage. A guard prevents the stump from directly engaging a cage net. A track belt produces efficient propulsion without damage to the cage net. The track belt includes flexible engagement stumps protruding from a base of a driving belt with tips or studs mounted on an end of the stumps.
Claims21
A track belt drive system used to advance a net cleaner on a fish cage net, said track belt comprising:
- a plurality of belt segments coupled together forming a continuous track belt;
- a drive wheel spaced apart from an opposite wheel, said drive wheel coupled to a motor used to rotate said continuous track belt around said opposite wheel;
- at least one flexible stump protruding from said driving track belt with net engagement features attached to each said stump for engaging and advancing said net cleaner;
- and a guard to prevent engaging said fish cage net with said flexible stump.
A track belt for use with a fish cage net cleaner, said track belt comprising:
- a plurality of belt segments, each belt segment having a first end with connectors for receipt of a first connecting pin, and a second end with offset connectors for receipt of a second connecting pin;
- a plurality of flexible stumps formed integral with each said belt segment;
- a stud releasably securable to each said stump;
- a guard member having a height above the surface of said belt segment equal to or greater than the height of said flexible stumps;
- and
- a belt formed integral with said belt segment extending around each said first end connector and said second end connector, said belt ends centrally located from said end connectors;
- wherein each said stud includes a shape constructed and arranged to engage a net and advance said belt segment, and stress on a belt distributing connecting pin is lowered by spacing said first connector pin a sufficient distance from said second connector pin.
