The conventional knapsack sprayers has certain limitation like poor work rate, problem of blockage of the nozzle, pressure drop after short duration of use and poor pressure resulting less effect of pesticides on the pests/insects, etc. The idea of making such device came from working on the limitation of conventional knapsack sprayer thereby providing higher productivity, higher pressure, less use of pesticides and effective operation.
This is an improved knapsack sprayer which contains pressure chamber, which stores the pressure for longer time after pumping. This sprayer also contains dual nozzle boom, which covers more spraying area. The present sprayer has also provision of changing stoke length for varying the pressure and feed rate.
