Groundnut Digger

Product: 

The innovator has developed a tractor operated machine, which mechanically digs out the left over pods from the soil. It consists of elaborate system of crankshafts, flywheel, connecting linkages and rotating vanes on a shaft. A sieve is provided with a vibrating mechanism to filter the groundnut from the soil. As the tractor moves forward, the vanes rotate and dig into the ground, scoop and drop the soil-groundnut mixture into a vibrating storage unit with a sieve base. The system of linkages and drives vigorously vibrate the entire unit to shake the soil loose and the groundnuts stay trapped at the top in the central storage unit as the soil gets sifted out onto the ground. A window hatch is provided at the back that can be lifted and the groundnut taken out by a person into a basket

Technical specifications:

• Traction vehicle:- A tractor (35HP or more)
• Length – 6 feet, Height- 1 feet
• Sieve – 5 feet x 5feet
• Gear Box to rotate PTO Shaft.
• It weighs 300-400 kg 

Key   Competitive Advantage: 

• It consume 4 liter of diesel/hr and digs out groundnuts pods of about 400 kg from one hectare per day, compared to manual method which would take 75 labours to finish in day.
• The units can also be run on uneven terrain and can be used to shift out small stones, solid residue and garbage from field and country roads.
