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.

Uses:
It is suitable for harvesting rice, wheat, soybean and other cereals
and oilseeds. The main advantage of this reaper is that there are no
shattering losses as it does not have reel. It drops the crop in
windrow and hence, it can be collected easily.

8.2 TRACTOR MOUNTED
VERTICAL CONVEYOR
REAPER
|
|
Features:
The machine consists of a 76 mm pitch reciprocating cutter bar
assembly, seven crop row dividers, two vertical conveyor belts fitted
with lugs, pressure springs, pulleys and gearbox for the power
transmission system. The crop row dividers are fitted in front of the
cutter bar assembly and the star wheels are mounted over the crop row
dividers. The machine is mounted in front of the tractor and the power
to the machine is given from tractor PTO with the help of intermediate
shaft running beneath the chassis of the tractor and a coupling shaft.
Height of the machine above ground is controlled by tractor hydraulics
with the help of pulleys and steel ropes. After the crop is cut by
the cutter bar, it is held in a vertical position and crop is
delivered to one side of the machine by lugged belt conveyors and fall
on the ground in the form of a windrow perpendicular to the direction
of movement of the machine. |

8.7 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. |

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.
