Toprak işleme aletlerinin analizinde ve tasarımında
üzerinde durulan parametrelerden biri çeki kuvvetinin azaltılmasıdır. Çizel
gibi büyük çeki kuvveti gerektiren toprak işleme aletlerinde bu daha önemlidir. Bu çalışma ile kanatlı çizelin kanat ağız
yapısındaki değişik formların (K1, K2, K3 ve K4) özgül çeki kuvvetine olan
etkileri incelenmiştir. K1 kanat yapısı düz bir ağza sahip olup geleneksel
kullanılan kanat yapısına benzemektedir. K2, K3 ve K4 kanat ağızları ise
farklı açılara sahip diş formundadır. Çalışmalar toprak kanalında
yürütülmüştür. Bu kanatlar üç farklı ilerleme hızında (0.12
m s^-1, 0.20 m s^-1 ve 0.28 m s^-1)
ve üç farklı iş derinliğinde (10 cm, 15 cm ve 20 cm)
denenmiştir. Kanat formunun özgül çeki kuvveti üzerine etkileri istatistiksel
olarak önemli bulunmuştur. En yüksek özgül çeki kuvvetinin düz ağızlı kanatta
(K1) meydana geldiği (1.25 N cm^-2) ve en düşük özgül çeki
kuvvetinin (1.03 N cm^-2) dar açılı dişlere sahip kanatta (K4)
meydana geldiği görülmüştür. İlerleme hızının ve iş derinliğinin artması özgül
çeki kuvvetini önemli derecede artırmıştır.

Determination of effect of different wing mouth forms, different travelling speeds and different working depths on draft force in wings used in winged chisel plough

One of the parameters contemplated in analysis and design of soil tillage tools is the reduction of draft force. This is more important for soil tillage tools as chisel shank which needs large draft force. In this research, effect of various wing mouth forms (K1, K2, K3 ve K4) on specific draft of winged chisel was examined. K1 wing mouth form which has a smooth mouth is similar to the form used conventional wings. K2, K3 and K4 wing mouth forms are the form of teeth with different angles. The study was conducted in soil bin. These wings were tested at three different travelling speeds (0.12 m s^-1, 0.20 m s^-1 and 0.28 m s^-1) and three different working depths (10 cm, 15 cm and 20 cm). Specific draft force was significantly affected from the wing forms. The highest specific draft force (1.25 N cm^-2) obtained from the smooth mouth wing (K1), and the lowest specific draft force (1.03 N cm^-2) occurred with the narrow angle teeth wing. An increase in travelling speed and working depth significantly increased the specific draft force.
