W'Üll işleme ve enerji geı eksilıimi yönündf!n geliştirilrnesidir. Bu amaçla birisi alışıla gelmiş tipleri yansıtan, diğer üçü de yeniden tasarlanem parmak profillerine sahip dört tip batöı ile denemeler yürütülmüştiir. Hann([l/lama etkinliğini yükseltmek amacıyla parmaklaı'ın batör miline lu,lisel biçimde dizi/me.>i sağlanmıştır. Bütün denemelerde baför ile kontrbatar arasındaki uzaklık aynı tutulmuş, parmak sayısı ve parmaklarm batöl' miline diziliş sıra sayısı değiştirilmemişıir.

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.Keywords :
