8.1 SELF-
PROPELLED VERTICAL CONVEYOR REAPER |
|
|
|
Features:
It is an engine operated, walk behind type harvester suitable
for harvesting and windrowing cereals and oilseed crops. The
reaper consists of engine, power transmission box, pneumatic
wheels, cutter bar, crop row dividers, conveyor belts with lugs,
star wheels, operating controls and a sturdy frame. The engine
power is transmitted to cutter bar and conveyor belts through
belt pulleys. During forward motion of the reaper, crop row
dividers divide the crop, which come in contact with cutter bar,
where shearing of crop stems takes place. The cut crop is
conveyed to one side of the machine by the conveyor belt fitted
with lugs and is windrowed in the field. The crop is bundled
manually and transported to threshing yard. There are no
shattering losses due to vertical conveying of the crop. |

train and is cut by the chopper drums into small cane pieces of
24.5 to 30 cm. It is then cleaned in the primary extractor
before being conveyed on the elevator. The can is then cleaned
again with the secondary extractor and loaded onto a vehicle for
transportation. In ideal conditions, the harvester can cut
nearly 400 tonnes of sugarcane per day. |

8.9 STRAW
REAPER/STRAW COMBINE
|
|
 |
|
Features:
Straw combine operated by tractor PTO has cutter bar reel,
feeding auger and bruising cylinder like a traditional thresher.
Straw thrown and stubble left by the grain combine is collected
by straw combine and delivered to the cylinder concave section,
where it is cut into pieces and passed through the concave. A
reciprocating cutter bar is used for reaping the standing
stubbles and the portion of the straw left uncut by the combine
harvester. Straw, which passes through the concave, is aspirated
by a blower and fed into a trolley on rear side covered by a
wire net. For recovering the left grains from the straw, a sieve
system is provided below the concave. |

|
  
|
|
Features
The tractor pto operated potato digger shaker consists of a
crescent/convex triangular shape-cutting blade, elevator rollers
chain generally made of iron bars, power transmission device,

helps in digging of the potatoes, which are carried to the shaking
conveyor belt and finally delivered at the rear of the machine in
windrows form. These are collected manually. The shaking belt helps
in removal of the soil from the tubers. These machines can also be
used for harvesting onions. In some models, discs are mounted in the
front to cut haulm or for guiding the blade along the rows.
