Discipline: Technology, Agriculture



The multi-purpose mechanized chopper was designed and fabricated using metalworking concepts. It has a housing frame 70 cm wide, 110 cm long, 80 cm high; with detachable spout and a rotating rotor which is mounted with eight (8) chopping blades, fifty (50) centimeters long. A 30 cm wide chute conveys the materials to be chopped to a chopping board with blades. It is powered by 7.5 hp diesel engine, the usual pump motor size for the “kuligligs” which is the popular service vehicle of most farmers nowadays. The machine could chop different farm wastes like stalks of corn, tobacco, banana, papaya, sugarcane, and rice whether fresh or dried. Its average speed is 100 kilograms in ten (10) minutes.

One unit of said prototype costs fifty three thousand nine hundred sixty six pesos (P 53,966.00), including its own 7.5 hp diesel engine, and only costs twenty nine thousand nine hundred sixty six pesos (P 29,966.000 ) without the motor.
