SELF-PROPELLED RIDING TYPE 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.

TRACTOR
MOUNTED VERTICAL CONVEYOR REAPER
|
|
Features:
The machine consists
of a 76 mm pitch reciprocating cutter bar assembly, seven crop
row dividers, and 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. |

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.
