Manually Operated Multi-Nozzle Pesticide Sprayer Pump

Farmers are the heart of Indian culture. Over 70% of the rural household depends on agriculture as their
principle mean of livelihood. The farmers comes under different levels according to their economic condition like
small, marginal, medium and rich farmers. Small scale farmers always prefer manually operated instrument instead of
developed instruments. In agriculture there are different filed work like weeding, reaping, sowing etc. Along these
operations spraying pesticide is an preliminary operation performed by farmers. To protect them from insects, dieses,
fungi and pests. Now a days number of technologies are used to spraying pesticide by using solar energy, electric
energy and chemical energy. We can simply use mechanical energy instead of these energies and these saved energies
can be utilised at appropriate place. Although using these developed instruments farmer suffer from different problems
like less capacity of sprayer tank, less working area, more cost as compare to manual, more time consuming etc. To
overcome these limitations number of product are launched in market, but they are not able to come over all the
limitations at a time. We find a solution over all these limitation by developing Mechanically operated multi-nozzle
sprayer pump for which any type of energy or fuel is not required except mechanical energy.
Motive of this paper is to generate a low cost sprayer pump for India’s poor range farmers and
reduce the required efforts. An accurate working model has been fabricated. It gives similar nozzle pressure and cover
maximum area. We used crank mechanism along with piston pump, which is derived by rotation of wheel.
