Bullock Operated Sprayer
Radheshyam Sharma of Ujjain (M.P) created a Bullock operated sprayer. The main components of the sprayer are self-made frame, lugged iron wheels, differential unit (of fiat car), belt and pulley drive, gear box, gear shifting lever, chain and sprocket drive, pump, spray tank (100 lit capacity), spray boom and nozzles. A pair of bullocks pull the device. The gearbox has three gears. When operator shifts the lever to higher gear, frequency of strokes of pump increases that consequently develops more pressure. As a result, the spray fluid atomizes into fine droplets with wider swath. When the gearbox is in neutral position, the drive to the pumping unit gets cut off. The suction pipe of the pump is connected to the spray tank and delivery pipe is connected to the spray boom. The height of the spray boom can be adjusted as per the requirement suiting to the height of the crop. The spray boom has 16 nozzles spaced at a distance of 35 cm. It is a low cost technology as compared to tractor operated boom sprayer. This product was introduced in the market in the year 2006.
