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.

8.6 SUGARCANE
HARVESTER |
|
Features:
It is a chopper harvester with a cleaning system and whole
cane harvesters are also available. It can cut one/two rows of
cane at a time. The cane is fed between the crop dividers and
is cut at the root zone by base cutter blades and
simultaneously de-topped from top. The cane is then fed
through the roller 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
cane 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. |

8.8 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. |

8.10 POTATO
DIGGER ELEVATOR
|
|
Features
The tractor PTO operated potato digger elevator consists of a
crescent/convex triangular shape-cutting blade, elevator rollers
generally made of iron bars, power transmission device and a tractor
hitching system. The crescent shape blade helps in digging of
potatoes, which are carried to the shaking conveyor belt and are
finally dropped at the rear of the machine in windrow form. These are
then collected manually. The shaking of belt helps in removal of the
soil from the potatoes. These machines can also be used for harvesting
onions. In some models, discs are provide in the front to cut haulm or
for guiding the blade along the rows.
