CMAD Larvicide Spreader

Team: Gavin Brown, Adam Seegmiller, Justin Winsor, Matt Flake

Sponsor: Cache Mosquito Abatement District

Project Description

Design a larvicide spreader that integrates with current oil spreading system that fulfills the following requirements:

Previous System

Previous System

  • Lighter Weight
    • Rack weight capacity is 187 lbs. Previous system was breaking the racks.
  • Directional Spreading
    • Must be able to spread to either side of the ATV.
  • Easier Calibration
    • System must stay calibrated

Design Description

  • Switched from steel to aluminum
  • Moved the center of gravity to be on the rack

Performance Review

  Previous System New System
Overall Weight of the System: 86 lbs 42 lbs
Directional Spreading 180 ° 45-180 °
Capacity of hte Hopper: 40 lbs 50 lbs
Capacity of the Oil Tank: 10 gallons 6 gallons

Conclusion

  • Significant Results:
    • The design is 1/2 the weight of the previous system
    • Spreads 180° with the option of 45° or 90° to either side of the ATV
    • Project was completed on time and under budget

  • Lessons Learned:
    • Tolerances are important to make parts easy to build
    • Load analysis can reveal where more structure is needed
    • Project planning should take into account shipping delays for components
  • Recommended Future Work:
    • Improve calibration box
    • Perform field testing
    • Improve storage method of the fence
