DIAGRAM OF OUTER BARREL
INNER BARREL: This is a Cylindercial barrel
which rotates with the shaft supported by end to end to bearing. The
diameter of the shaft is 20mm and for the inner barrel diameter is 190mm
having 20 numbers of spikes measuring 30mm from the barrel surface and
also wounded vanes that does the operation. Diameter of inner barrel is
120mm and its length is 740 and consequently the diameter of the shaft
is 20mm. Below is the diagram of the inner barrel.
DIAGRAM OF INNER BARREL.
TRAY:
This is just similar to a pot but the different is that it is bigger
and not covered and have a rectangular shape. There is a provision of
an entry through which the corn enters the shelling chamber and the
inner engulfing the shaft. It is obtained after cutting a mild steel and
welded with guage 12 Electrode and it has its dimension as 740mm x
100mm.
The diagram of the tray is as shown below in the fig.
DIAGRAM OF THE TRAY
RECEPTACLE:
This is the outer funnel that collects the shelled corn from the
conveyor to the outside. It is welded to the below of the outer barrel
SPIKES
: This is the rod attached to the surface of the inner barrel which
does the shelling action with the Ina barrel and the spring vanes. It
is up to 20 in number and measures 20mm vertically up from the inner
barrel surface each.
COB OUTLET: This is an exit through which cobs goes out of the barrel after shelling process to the external environment.
CONVEYOR:
This is a carrier that carries the cobs out of the barrel after selling
process. It is run on the body of the inner barrel and is about 20mm in
height but runs in a snake like movement from end to end of the inner
barrel.
Fig.
DISCHARGED CHAMBER:
The are holes perforatedf below the outer barrel through the shelled grain falls out to the conveyor.
COLLECTOR/OUTLET BASIN:
This is curved mild steel welded below the perforated outer barrel
inclined to an angle to enable the falling out of the shelled corn to
the receptacle.
INLET:
This is the particular place in the tray
through which the corn enters the shelling unit chamber for shelling
process. It is about 180mm in length and 80mm in width.
SPRING VANES:
This
is made up of flat tiny metals welded round the barrel together with
the spikes. It is the part of the machine where corn are shelled. It
is always capable of withstanding impact from the corn and posses good
chemical resistance, high working temperature (100%) and tensile
strength. Dimensionally. It is measured from the surface of the inner
wounded horizontally.
Finally, after much analysis and
synthesis, the design is of minimum cost, simple to operate easy to
construct, durable and easy to maintain.
We hop our work will
certainly provoke great interest in the reader as it house a lot of
useful information for furtherance of engineering education and
productivity.
