oscillating box, straw walker, and winnowing and cleaning
attachment. The rasp-bar cylinder is made of cast iron rings,
sheet metal and toothed racks and is fitted on the main shaft
running on two numbers of heavy pedal bearings. Various pulleys of
different sizes are fitted on this shaft to transmit power to
winnowing and fan attachment. Adjustments for cylinder and blower
speeds and concave clearance are provided to make the machine
suitable for various crops. |

AXIAL- FLOW PADDY THRESHER
|
|
 |
|
Features:
It consists of a spike tooth threshing
cylinder, concave, cylinder casing, cleaning system and
feeding chute. In axial flow concept, the crop is fed from
one end and the straw is thrown out from the other end after
complete threshing of crop. During threshing, the crop
rotates three and half times around the cylinder and all the
grains get detached. The threshing cylinder is of peg type.
The casing of the thresher has 7 louvers for moving the crop
axially. Two aspirator blowers and two sieves are provided
for cleaning. |

|
Features:
The thresher is an axial flow type and it
consists of feed hopper, spike-tooth cylinder, concave,
oscillating sieves and blower. The pegs are arranged in 10 rows on
the cylinder. The cylinder is enclosed with the concave made of
wire mesh with sieve opening of 80 x 25 mm size. Below this
cylinder and concave assembly two oscillating sieves are fitted to
separate the pods from leaves, soil and dust particles. The blower
fitted between the two sieves helps to blowout the leaves. The
thresher is also suitable for freshly harvested crop with green
vines.
