It consists of a digging blade of 1200 mm length, an elevator shaker, idlers, driving sprockets, two disc coulters two gauge wheels, fenders and gearbox. The front end of the picker elevator reel is adjusted in accordance with the depth of working of the blade. The angle of the shaker conveyor is 30 degrees with horizontal and has a length of 1270 mm. The digger is operated by a tractor of 35 hp or higher. The PTO through a telescoping shaft supplies power to the gearbox of the machine. It digs the groundnut vines below the pod zone and elevates them by an elevator-picker reel (conveyor) for dropping on the ground. The soil attached to the vines is shaken off in the process and a windrow is formed with the help of deflector rods. The vines are dropped in such a manner that the pods get exposed to the sun for speedy drying.

8.8 BANANA HARVESTER (CHOPPER)

 

Features:

 

Chopper is a simple harvesting hand tool, which consists of a blade, tang and a handle. The cutting edge is slightly curved (convex) along the cutting edge to facilitate the cutting. The blade is joined to the handle by inserting its tang. The blade is forged to knife section and cutting edge sharpened. The blade is important part of the tool and is made from medium carbon steel, high carbon steel, manganese steel or alloy steel including tool steel. The cutting edge is hardened and tempered to suitable hardness to resist wear and abrasion. The tool made from tool steel and alloy steel has more service life as compared to the plain carbon steel blade. The blade should have property of toughness to resist the impact stresses. The handle is made of wood and shaped to suitable handgrip. For operation, the blade is struck hard against the stem with one hand and the cutting is accomplished by the impact action and sliding of the blade along the stem. The shape and size of the chopper varies from place to place and its use.

8.10 TURMERIC HARVESTER

 

 

Features:

 

The unit consists of a blade with three bar points for easy penetration into the soil. To the rear end of the blade six slats spaced at 50mm apart are hinged at both ends. The oscillating motion for the slats is obtained through eccentric provided on either side of the unit. The eccentrics are connected to a shaft provided at the top portion of the unit. The power is transmitted from the clutch pulley of the power tiller to a reduction gearbox mounted near the hitch bracket assembly of the power tiller. From the gear box, the power is transmitted to the shaft of the turmeric digger unit through V - belt transmission. The pneumatic wheels are replaced with a pair of special type cage wheels to accommodate the height of ridges.
