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, pressures 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 hydraulic
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 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
machine.

SELF-PROPELLED REAPER BINDER
|
Features:
It consists of a frame, cutter bar, handles fitted with clutch and
brakes, seat for the driver, two drive wheels, one wheel below the
seat for steering, crop gathering unit and twine. The cutting unit of
this type of reapers may be disc type or cutter bar type. After
cutting, the crop is conveyed vertically to the binding mechanism
where it is tied by the twine and released to the ground in the form
of bundles. Self-propelled walking type models are available but these
are not popular due to high cost of twine. Reaper binders are suitable
for rice and wheat.

SELF-PROPELLED COMBINE HARVESTER
|
Features:
Various designs of combine harvester having 2 to 6 m long cutter bar
are commercially available. The function of a combine harvester is to
cut, thresh, winnow and clean grain/seed. It consists of header unit,
threshing unit, separation unit, cleaning unit and grain collection
unit. The function of the header is to cut and gather the crop and
deliver it to the threshing cylinder. The reel pushes the straw back
on to the platform while the cutter bar cuts it. The crops are
threshed between cylinder and concave due to impact and rubbing
action. The threshed material is shaken and tossed back by the straw
rack so that the grain moves and falls through the openings in the
rack onto the cleaning shoe while the straw is discharged at the rear.
The cleaning mechanism consists of two sieves and a fan. The grain is
conveyed with a conveyor and collected in a grain tank.

SHRUB MASTER
|
Features:
It consists of cutting blades (swinging flails) fixed to the rotating
bar, gear box for transmission of power at right angle, universal
joints with telescopic shaft to connect the tractor PTO and gearbox,
adjustable side skids for controlling cutting height of shrubs or
grass, safety guard and hitching frame. It is a operated by tractor
PTO. The bar having cutting blades fixed at the ends is mounted on the
gearbox shaft. Thus, the vertical shaft of the gearbox provides rotary
motion to the bar. The cutting blades mounted on the bar swing open to
the cutting position due to centrifugal force as the bar rotates in
the horizontal plane. The cutting takes place purely through impact
and flails need not be sharp-edged. The blades are made of medium
carbon steel or alloy steel and hardened.
