Asella Teff Thresher

Description of the machine
The developed teff thresher consists of main frame, feeding hopper, threshing drum, separating and cleaning mechanism.
The main frame is the skeletal structure of the machine on which all other components are mounted on it.
A trapezoidal feeding hopper was designed and made from mild steel sheet metal and bolted with top drum cover and the frame.
It will be removed during transport. The threshing and separation unit consists of threshing drum, lower perforated concave, upper concave and straw auger.
The drum was made from a cylinder of 500 mm in diameter and 850 mm long. The concave is the lower half of the drum perforated with 2 mm in diameter to
serve as discharge holes for the teff and other fine materials. The cleaning unit consists of blower, sucker mechanism and cleaning sieve. The cleaning activity
is accomplished by suction pressure created by blower and sieve.
