<h4>9.1 MULTI -CROP THRESHER
</h4>
<img src="image2/9.1.png" alt="" srcset="">
<h5> Features</h5>
<p>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. It has a safe feeding chute attached to it as per BIS standard.
I hilly tracts small power threshers need to be introduced.

<h4>9.2 AXIAL- FLOW PADDY THRESHER
</h4>
<img src="image2/9.2.png" alt="" srcset="">
<h5> Features</h5>
<p>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, it 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.</p>

<h4>9.3 PEDAL OPERATED PADDY THRESHER
</h4>
<img src="image2/9.3.png" alt="" srcset="">
<h5> Features</h5>
<p> It consists of wire-loop type threshing cylinder, power transmission system, mild steel sheet body
and foot pedal. The threshing cylinder consists of wire-loops of ‘U’ shape embedded in wooden or
metallic strips joined to two discs. A shaft carries the threshing cylinder and is connected to the
transmission system. The transmission system consists of meshed gears or sprocket-chain mechanism.
The larger gear or sprocket is connected to foot pedal/bar with links. The foot pedal/bar is always
in raised position. On pressing the pedal the threshing cylinder starts rotating. For continuous
rotation of the cylinder, the pedal is lowered and raised repeatedly. For operation, paddy bundle is held in hands and earhead portion of the crop is placed on the rotating cylinder.
The wire-loops hit the earheads and grain get detached from the rest of the crop.</p>

<h4>9.4 MAIZE DE-HUSKER/SHELLER
</h4>
<img src="image2/9.4.png" alt="" srcset="">
<h5> Features</h5>
<p>Maize de-husker cum sheller are of two types namely, spike tooth type and axial flow type.
In the spike tooth type sheller, pegs are staggered at varying heights for better shelling efficiency.
The spikes are placed in 6 rows with 6 spikes in each row. The sieves have 1.25 cm diameter opening to separate the shelled maize from husk.
In axial flow type threshers, pegs are provided on the cylinder
and louvers were provided on the upper periphery of the drum to convey the crop to the outlet.</p>
