3. Project concept
A conveyor belt has been designed constituting of deflector connected to a chain.
conveyor belt is used for transporting the forage from the store to the barn.
deflector is used for distributing the forage off the conveyor belt into the feeders, in predetermined quantities to cater for the daily consumption of each cow.

4. Project concept
Both conveyor belt and chain move in the same direction with the speed of the conveyor belt twice that of the chain.
Once the deflector riches the end of the line a limit switch is used to bring the whole system to a holt.

8. Design parameters Numbers of cows = 34 cow/row. Forage type is Alfalfa
Rate of forage consumption 12.5 kg/day.
Length of feed bunk = 25 m.
Forage distribute once a day.
Feeding space = 0.7 m/row.
Forage distribution time 6 min.

9. Design calculations
Configuration of forage on belt:
= 438 kg

22. Conclusion The design arrived at seems to be:
practical and efficient in distributing the sufficient daily requirements of feed for 34 cow in just 6 minutes.
Could be cost effective.

23. Conclusion The design arrived at seems to be: Safe.
friendly to the environment.

24. Recommendations
Implementation of this work in a workable prototype to be tested in an actual housing facility.
Storage control.
