The Study of the Effect of the Rotational Speed and the Horizontal Distance Fingertips to Nose on the Head Losses of Wheat Stripping

摘要

Wheat is one of the major food source for the people of Iran. Wheat harvesting methods traditionally have large losses that to reduce it, use of stripping. In this study developed a head stripper was designed and built in accordance with agricultural land in Iran. Then, to test and evaluate the effect of the rotational speed and the horizontal distance fingertips to nose on the loss of seed shattering , made head stripper that was bring them into wheat lands in the city of Gonbad in Golestan Province. Analysis of variance showed that the effect of the rotational speed and the horizontal distance fingertips to nose and as well as their interaction on seed shattering losses and spikes was significant at 99% confidence level.
