Bicycle Sprayer


To find out the way, Mansukhbhai Jagani, a farmer cum artisan with a passion for mechanical innovation developed a bicycle operated sprayer, which is very efficient and affordable by the farmers. It is an attachment, which essentially uses the circular motions of the cycle sprocket to move the piston of the spray pump which generates pressure to spray the pesticides. The front and rear sprockets of a thrown away bicycle are interchanged and the small sprocket is connected to the piston pump, so as the circular motion is converted to reciprocating motion of the piston and thus the pressure is generated and thus the pesticides are sprayed on the field.
