Features The
thresher consists of rasp bar threshing cylinder, oscillating sieves, concave
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 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 machines suitable for threshing various crops. |

Features It
consists of a threshing cylinder, concave, cylinder casing, cleaning system and
feeding chute. In axial flow concept, the crop is fed from one end, moves
axially and the straw is thrown out from the other end after complete
threshing of the 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. |
