SUMMARY

A Research on the Domestie Threshers for Improvement Possibilities of Drum Construction

Domestk thresher is öne of the
moSt important machine of agriculturaı
mechanization in Turkey. The improvement
possibilities of thei[ drum construction
·is the main aiın of this research'
work. For thispurpose, drums
with one orginal type and three new
design types teeth were chosen as the
mate"ıia!. Broken damage, drum loss,
average torque, average power requirement;
and spesific energy consiırnption
of these toothed drums have beel1
deterınined ıııid m~iisurcd, and com pared
\vith cach· other. Yayla 305 whcat
and Lancer wheat varielies have bccn
thres.hed in the experiments..
Resull ohtained can be summarized
as foll.ows:
f, Htoken grain occurred i ,80 ~~,~ for
. origina! toothed drum, J ,74~·~) for
A type toothed drum, 0,93 ~~~ for
B type toothed drum, and 0.06 ~'~
for C type tonthed drum at the all
experiments with three drum periphcral
speeds, three rates of fecd
and two varieties· of wheat.
2., Drum loos occurred 3.79 ~/;. for
original toolhed drum, 3.33 ~~:~ for
.A type toothed drum, 3. 13 '/.; fol'
B type toothed drum; and LOI ~o
for C type' toothed drum at the an
experiments with three drum peripheral
speeds, threerates of feed and
two varieties of wheat.
3: The average torque results of C type
toothed drum was obtained less lhanorigina! typl':' toothcd d,rum and A
type toothed drum.
4. Average power rcquirer)ıent çletermined
2.3'1 'kW for. origin:ıl toothod
drum. 2.16 kW for A typo ·toothcd
drum, 1,98 kW for B type toothed
drum, and L. 76 kW fal'. C typc .toothecl
dru III at the all experimcn ts
with three drum peripheral spcods,
three rate:' of feed and t\YO varieties
of wheaL
5. Specific energy consumption OCCUTred
1.50 kWh/Mg for original toothed
drum, 1.43 kWh/Mg for A ıype
toothed drum, 1.29 kWh/Mg for B
type toothed drum, and 1.18 kWh/
. Mg for C type toothed drum at the
all experimcnts with three drum
per!phera! speeds, three rates of feeri
and two varieties of wheat:
Ac.cording to the results of this
reseaıch the savings of C type toothed
drum 96. 67 ~~, 73,75 % and 21.33 ~,{,
for hro.ken damage, drum loss and specific
cnergy comıııııptian rt'spectively.
