Mission Objective

  • Litter Application Component:

“To improve or redesign the walls of the poultry litter implement so that litter can be more effectively distributed to the soil, mitigating the clogging that currently occurs during normal operation”

  • Dirt Recovery Component

“To improve or replace the current press-wheel system used

  • n the implement for dirt recovery so that the extricated

soil is more effectively replaced over the deposited litter band”

Conclusions

  • Redesigned Trencher Walls

– Increase thickness to ¼ inch, flare outward at 10 degrees – As proven by ANSYS, deflection will not inhibit poultry litter flow

  • Soil Recovery Component

– Maximum shear in pivots is 14 lbs – Materials chosen are sufficiently strong for intended application
