1.2 IMPORTANCE AND SPECIFICATION OF THE PERFECT
The
importance attached to this design is the facilitation and the
production of voluminous corn shelling without much time and without
encountering much breakage of the grains of the corn in shortest
possible time.
The specification was obtained considering the items
or component used and the hopper and barrel dimensions put into
consideration as well. The design parameter for corn sheller machine
are:
1.2.1 BARREL
(a) Outer barrel:- This
barrel do not rotates with the shaft rather stands on itself inside the
shelling chambers. It is a half of glindrical shaped perforated below
to enable shelled corn to rush out to the conveyor to the outlet basin.
It is weld and tight at ges at the end for the location of the bearings
for the shaft. At the lower end of one is an open segments serving as
outlet for the cobs and a hood is built covering it.
Below is a complete drawing of the outer barrel shown.
DRAWING
(B)
Inner barrel:- This cylindrical barrel rotates with the shaft support
by end to end bearings. The diameter of the shaft is and for the inner
barrel’s diameter is, having number of spikes measuring from the barrel
surface and also wounded vanes that does the shelling process.
Diameter of inner barrel is and its length is and consequently the diameter of the shaft and having a length of.
Below is the diagram of the inner barrel
1.2.2 HOPPER
This
is similar to a port but the difference is that it is bigger and not
covered like the port. It is eight rapezoid or rectangular in shape,
each shape chose have its advantage and disadvantages. It has 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
welding it with gauge 12 electrode and it’s dimension is.
The diagram is shown below.

ABSRACT - [ Total Page(s): 1 ] A machine for corn shelling is highly and greatly needed to consistency of usage of corn in local and international levels. With regards to this indispensable needs, a corn shelling machine is designed which operates to remove the corn grains and leaving the cobs intact. In attainment to this design objective and aims, a proper considerations was given to the machinability factor which includes; installation, simplification, durability, choice materi ...
